TRANSLATORS'  PREFACE. 


The  very  high  reputation  acquired  throughout  Europe  hy  the  Patho- 
logical Histology  of  MM.  Comil  and  Ranvier  as  a  clear  and  excellent 
presentation  of  this  important  department  of  Medical  Science  would  seem 
to  be  a  sufficient  juatificatipn  of  the  present  effort  to  make  it  accessible 
to  the  American  student. 

In  France,  the  work  appeared  in  several  portions,  at  intervals  extend- 
ing from  1869  to  1876.  The  earlier  parts  are  therefore  somewhat 
behind  the  existing  state  of  knowledge  and  opinion.  Moreover,  the 
book  is  very  large,  and  in  some  portjona  difiusoly  written.  It  has  been 
the  endeavor  of  the  Translators,  by  omitting  such  passages  as  are  com- 
paratively unimportant  or  have  become  obsolete,  by  condensing  others, 
and  by  inserting  additions  where  the  progress  of  science  has  seemed  to 
call  for  them,  to  render  the  American  version  a  more  faithful  exponent  of 
the  subject  in  ita  present  state,  and  at  the  same  time  to  bring  it  within 
the  compass  of  a  convenient  text-book  for  the  student.  The  additions 
are  scattered  throughout  the  volume,  and  are  generally  inclosed  within 
brackets  [J.  The  most  extensive  changes  will  be  found  in  the  sections 
on  Sarcoma,  Carcinoma,  Tuberculosis,  The  Bloodvessels,  The  Mamma, 
and  The  Classification  of  Tumors. 

Corresponding  alterations  have  been  made  in  the  series  of  wood-cuts. 
In  this  connection,  thanks  are  due  to  the  Surgeon-General  of  the  Army, 
and  to  Dr.  J.  J.  Woodward,  U.S.A.,  for  their  kind  permission  to  use 
some  of  the  important  illustrations  in  the  second  part  of  the  medical 
volume  of  the  Medical  and  Surgical  History  of  the  War. 

The  foothold  which  the  metrical  system  of  weights  and  measures  is 
gradually  gaining  in  this  country,  the  wide-spread  adoption  of  that  sys- 


ÎY  TRANSLATOBS'   FBBFAOE. 

tem  by  the  scientists  of  Europe,  and  the  desirability  of  the  employment 
of  Bciendfic  terms  having  a  veil  recognized  significance  the  world  over, 
have  led  the  Transistors  to  retain  the  metrical  values  whenever  dimen- 
sions have  been  expressed,

AUTHORS'  PRKFACE. 


Tue  absoDco  of  a  French  work  upon  p&tbological  bistolog;  luu  deter- 
mined us  to  publi»h  tbîs  book. 

Tbe  title  wlikli  yre  bave  chosen,  MamuU  of  Paihdogictâ  Biutotog^^ 
indicate»  tlie  object  of  its  publîcattoD,  viz.  :  that  of  proeenting  a  brief, 
eleineotarj,  and  succinct  explanation  of  the  deticnptions,  definitions,  and 
clusifioaliona  of  morbid  pro>IucU  as  aeon  under  the  microscope.  Our 
book  lins  itot  been  named  J'uihiflogicai  Anutomif  lfecau»c  it  U  l>a»ed 
entirety  upon  normal  histolog;\' — a  department  of  medical  acienco  from 
which  «e  hAvc  borrowed  both  clasetfiCfttioi»  and  methods. 

This  title  implies  the  neceuity  of  paying  little  attention  to  naked-eye 
desoriiitioiis,  which,  indeed,  are  «o  complete  ami  satUfaclury  in  tlic 
classical  works  of  Cruveilhier,  Andral,  Ilouillaud,  and  others,  thu  it  ta 
impossible  to  rival  them  or  to  succcsitrully  abridge  tbem. 

The  material  which  lia«  been  utilised  for  the  composition  of  this 
manual  is  derived  from  autopsies  and  operations  in  the  hospîtaU  of 
Pari»,  80  rich  in  this  respect  that  a  tenth  part  of  the  material  daily 
wasted  there  would  amply  suSico  for  tbo  supply  of  the  most  actire 
laboratory.  And  her«  we  desire  to  exprcM  our  acknowledgments  to  our 
colleagues,  to  our  friends,  and  to  our  chiefs,  physicians  and  surgeons  of 
the  hospitals,  by  whose  camest  cooperation  most  interesting  spcctmcnB 
have  been  placc-d  at  our  disposal.  The  examination  of  this  material  was 
made  by  our  pupils  and  by  ourselves  in  our  own  êpccial  hiffirator^ — 
our  manual  being  the  pathological  complement  to  the  histological  counc 
irhich  we  have  given  for  four  years. 

A  knowledge  of  normtû  hiitoioffff  U  indispensable  for  a  comprchensioQ 
of  pathological  histology.  Although  upon  that  subject  the  French  trans- 
la^ou  of  the  treatise  of  KoiUker  and  that  of  t'reys'  ilistologj',  in  course 
of  publication,  giro  full  instruction,  we  have,  nevertheless,  concluded  U) 
offer  a  brief  réunnii  of  normal  hislologj'  before  entering  upon  the  study 
of  patliological  histology.  Hence  the  first  chaptor  comprises  a  general 
examination  of  tlie  conatimtion  of  cells  and  of  normal  tissues.  Further- 
more, the  normal  histology  of  each  organ  is  rapidly  reviewed  before

AUTHORS'    PREFACE. 


commeDcîng  the  study  of  its  patbology.  The  arraDgcmcnt  of  this 
manunl  is,  cooB«q[Uent1y,  the  sauu  as  that  of  a  troatisc  upon  oornial 
liUwlogj. 

General  pathology  corresponds  to  ffeneral  hittoloifi/,  and  comprises  the 
lesions  of  cells  aud  of  tisaueiii  as  well  a»  th^  nature  of  iaflanimatioD  and 
of  tumors.     Tht«  occupies  the  first  part. 

To  tpccial  hi»U'}<igy  corresponds  »)'enal  pitlhoîoijy,  which  is  divided 
into  two  parti!  :  the  one.  devoted  to  the  lesion»  of  each  of  the  ti*su<-*  and 
systems;  tlie  other,  to  the  alterations  of  each  apparatiia  and  particular 
organ.  In  this  Last  part  our  pupil  and  friend,  M.  Terrillon,  lias  added 
his  labor  to  ours. 

We  disclaim  allegiance  to  any  school,  belonging  neither  to  the  Oer- 
man  nor  to  the  so-called  Freneh  »ehool.  The  latter  appellation  Ja  incon- 
gruous, since  it«  real  chief,  Professor  llenle,  is  a  German.  We  are 
opposed  lo  such  divisions,  for  tliey  woold  compromise  science  itself  in 
the  dissensions  of  savants — science,  a  unity  indivisible  *g  truth.  In 
making  oar  contributions,  it  behooves  us  to  justly  ai>preciatc  the  labor» 
of  others,  and  to  observe  our  facta  with  exactness. 

Uut  little  space  has  been  accortled  to  Aisfory,  because  in  writing  for 
beginners,  we  deemed  it  necessary  above  all  to  state  simple  facts  and 
ioterprotatioiia  wliicb  wc  believed  to  bo  tnic.  The  office  of  a  muiual  ia 
neitlier  to  relate  nor  to  cricicixo  every  opinion  which  has  been  advanced. 
Tlie  omission  of  the  discussion  of  theories  and  doctrines  has  not  been 
})ecause  we  have  coni^dered  them  useless  or  barren,  but  rather  becauM 
tills  was  not  the  proper  place  to  examine  them. 

It  had  been  our  desire  to  bead  each  part  of  human  pathology  by 
introducing  a  chapter  upon  rjrptrimentaî  pathohnjg.  But  the  former 
-will  be  well  understood  only  when  the  lalt«r  shall  have  no  more  mas- 
teries to  solve.  Notwithstanding  the  fnot  that  experimental  patholo^^, 
under  the  powerful  impulse  of  CI.  Bernard  and  of  Yirehow,  has  alrejidy 
had  a  vigorous  beginning,  and  that  both  experimental  physiology  and 
histology  have  tended  to  stimulate  its  development,  how  much  remains 
to  be  discovered  !

PATHOLOGICAL  HISTOLOGY. 


PART  I. 

GENERAL  PATHOLOGICAL  ANATOMY. 


CHAPTER  I. 

NORMAL  HISTOLOGY— CELLS  AND  NORMAL  TISSUES. 

Beet.  I.—Cell  Theory  and  Strnctnre  of  CelU. 

Before  entering  upon  the  studj  of  pathological  hiatotogj,  a  summary 
of  our  knowledge  of  normal  histology  ia  given,  in  order  that  the  principles 
which  underlie  pathological  changes  may  be  understood. 

Histology  was  founded  by  Biehat.  It  received  its  further  development 
by  Schwann,  who  applied  to  it  the  discoveries  made  by  Schleiden  in  the 
vegetable  tissues.  It  came  to  be  recognized  that  the  cell,  whether  aniinal 
or  vegetable,  is  the  organic  unit,  pur  excellence — the  simplest  body  wherein 
life  ia  individualized.  It  was  then  well  known  that  some  living  heinga, 
possessing  the  functions  of  nutrition,  movement,  reproduction,  birth,  and 
death,  consist  simply  of  a  single  cell. 

In  beings  more  complex,  the  cells  are  surrounded  by  an  intercellular 
substance  to  form  tissues  and  organs  of  which  the  cells  are  the  essential 
part,  still  playing  the  principal  role  ;  but  the  cells  may  be  so  modified,  that 
they  can  scarcely  be  reco;5iiized,  if  their  metamorphoses  are  not  regarded. 

According  to  Schwann  the  cell  ia  composed  of  an  enveloping  mem- 
brane ;  of  contents  more  or  less  fluid;  of  a  nucleus;  of  one  or  more 
nucleoli  within  the  nucleus. 

In  regard  to  the  formation  of  cells  Schwann  admitted  &  free  format  ion 
(spontaneous  generation)  in  a  primordial  generative  fluid,  whetlier  the 
latter  be  found  alone  or  be  placed  between  pre-existing  cells  (blastema  or 
cystoblastema).  According  to  him,  granules  appear  in  the  liiiuid,  rudi- 
mentary nucleoli;  around  these  new  granules  become  visible,  and  sur-

arise  from  pre-eiiatinj:  cells,  in  one  of  three  ways  :  by  teqmnntation  or 
diviuftH,  by  gemmation  or  hudiiing,  and  by  eiidogenoua  formation.  Ac- 
cordin;;  to  die  present  conception  of  the  cell,  these  three  modes  are  not 
essentially  distinct,  ,

the  definition  of  the  cell  given  by  :^chk-iden  and  tichwami,  recogni;iud  a 
memlirone,  contents,  nucleus,  and  nucleolus. 

f^iilise<]uently  through  the  lahors  of  Max  Schnltse,  von  Recklingliauson, 
Kiihiie,  Iteale,  etc..  the  definition  of  the  cell  has  been  much  moililied. 

Dujnrilin  had  previously  remarked,  that  inferior  beings  consisting  of 
a  Bingle  cell  were  not  always  enveloped  by  a  membrane,  hut  that  they 
often  consisted  of  a  mas»  susceptible  of  change  of  shape,  to  such  a  degree, 
that  very  long  prolongations  might  bo  advanced.  To  these  masses 
Duiardin  gave  t]ic  name  of  MfiWr,  and  their  movements  he  termed  mr-

cells  found  in  the  same  substance  ;  4th.  The  white  corpuscles  of  the 
blood;  5th.  Lyraph  ceils. 

Emhryonic  cell»  consist  of  an  irregular  mass  of  granular  protoplasm, 
which  may  be  spherical,  measuring  from  .01  mm.  to  .01.5  mm,  in  diameter, 
are  swollen  by  water  and  acetic  acid,  colored  brown  by  a  solution  of 
iodine,  and  faintly  by  carmine  which  increases  the  granular  appearance. 
Tliia  protoplasmic  mass  incloses  an  oval  or  spherical  nucleus  frequently 
seen  only  aft«r  the  action  of  acetio  acid,  possessing  a  double  contour  aud 
a  nucleolus  often  very  small  and  which  is  deeply  colored  by  carmine. 
Instead  of  one  nucleus,  if  the  cell  tends  to  a  retrograde  change,  there  are 
frequently  several  small  and  angular  nuclei  ;  if  the  cells  tend  to  growth, 
the  nuclei  are  spherical  and  well  developed. 

In  the  developing  layer  of  bone  from  cartilage,  cells  are  met  which  ao 
closely  resemble  embryonic  cells  that  there  is  no  characteristic  sufficient 
to  distinguish  one  from  the  other.  In  consequence  of  the  changes  which 
these  cells  undergo  they  become  slightly  separated  from  the  primitive 
type. 

The  large  multinucleated  cells,  which  are  found  alongside  of  the  fore- 
going, apart  from  the  multiplicity  of  their  nuclei,  from  their  great  irregu- 
larity of  contour,  and  from  the  buds  which  they  present,  possess  the  same 
general  properties  as  the  embryonic  cell  ;  the  protoplasmic  substance 
which  forms  them  gives  the  same  reactions.  Later  these  elements  be- 
come flattened,  more  consistent,  and  separated  from  their  original  type. 

Among  the  white  corpuscles  of  the  blood  two  kinds  are  recognized:  the 
one  incloses  a  single  round  or  oval  nucleus  with  a  distinct  nucleolus  which 
re.-iists  the  action  of  acetic  acid  and  is  colored  by  carmine  ;  the  other  con- 
tains several  small  angular  nuclei  or  a  single  nucleus  which  breaks  into 
fragments  on  the  addition  of  acetic  acid.  We  believe  the  latter  to  be  in 
a  state  of  retrograde  metamorphosis.

Embryonic  cells  are  destroyed  or  they  undergo  a  series  of  modifica- 
tious  which  characterize  their  appearance  as  seen  in  the  diBerent  tissues. 
Thtf  simplest  example  of  modincaâon  of  embryonic  viemcnis  is  that  in 
vhich  there  is  an  elaboration  of  a  now  substance  in  the  protoplasm.  This 
is  seen  in  the  early  dcvclotiment  of  adipose  cells,  where  tlie  protojilniun

Still  undneideil  whether  the  membrane  is  a  condensation  of  the  superficial 
layers  of  the  protoplasm  or  is  an  excretion  of  the  cell.  Whatever  it  may 
be,  it  is  entirely  distinct  from  the  protoplasm.  As  soon  as  a  celt  is

its  nucleolus  is  well  develoj*d. 

The  cartilage  ecU  does  not  present  any  char, 
acterisiic  sufficient  to  diaiinguish  it  when  iso- 
lated, and  it  is  only  because  it  occupies  a  place  in  cartilaginous  tisane, 
that  the  name  cArtilagc  cell  is  given  to  it.  This  cell  cannot  therefore  b« 
defined  by  its  physical  characters,  but  only  by  the  pruperty  it  possesses 
of  forming  around  it  a  secondary  membrane  of  cartilaginous  substance 
tunned  a  cap«ule  (fig.  12). 

When,  in  tJie  deveiopnicnt  of  embryonic  tiiwue,  cartilaginous  tiMue

has  all  the  cbaraetei-â  of  oartilnginous  subiilance.  The  formation  of  this 
substance  is  at  tiriit  slow,  it  soon  increases  and  condenses  as  a  capsnle 
around  llie  cells.  The  capeule  may  al*>  be  the  result  of  a  new  produc- 
tion of  the  cell  itself.  This  is  (he  rinf-r^ottic  variety  of  cartilage  in  which 
cells  and  capsules  are  small  an<l  spherical.  Soon  the  cellular  elements 
multiply  ;  at  this  stage  there  are  freciuently  i^ven  two  ntwlct  in  a  cell. 
While  dividing,  the  nucleus  at  finrt  enlarges,  elongate*,  contracts  at  tl»e 
middle,  and  finally  separates  into  two.  The  division  of  the  protoplasm 
occurs  after  that  of  the  nucleus  ;  consequently  we  often  have  cell»  with 
two  nuclei.  Pitch  of  the  new  cellular  masses  posaes^es  the  property  of

The  meiltiUnry  cavilieii  contain  the  marrow  and  Moodresaels.  Id 
nearly  all  long  boneii  these  cavities  are  cylindrical,  and  parallel  to  the 
long  axis  of  the  bone.  Titer  are  known  &«  tiaventian  canals,  and  are

from  compact  bones  except  in  the  sise  aii<l  irregularity  of  their  canals. 

The  marroiv  of  hmt  is  always  traversed  by  bloodreesels.  Between

to  the  state  of  derolopaient  of  the  osseous  tissue.  In  the  bones  of  the 
extremities  adipose  cells  predniniitate  ;  in  the  bodic«  of  the  vertehrvc  and

The  fonnation  of  a  pathological  tissue  from  a  healthy  tissue  wbicb 
differs  from  it  has  been  called  by  Virehon  heteroptatia.  The  development 
of  osseous  tissue  from  cartilaginous  and  fibrous  tissues  is  the  physiological 
type  of  lieteroplftsta.  Virchow  has  not  so  considered  it,  because  he 
declares  that  o*m-oim  and  cartilnjiinoiis  tissues  are  the  same  histohigioaily, 
and  Iiecausi?  he  l»elii;ves  that  osseous  tissue  arises  bv  nutritive  changes  of

The  flrment»  ■>/  ori/iiHlc  mutilti  are  fik^iform 
cells  greatly  varying  in  length:  no  enveloping

to  consist  of  an  albuminoid  substance  (muscular 
fibrin),  transparent,  refracting,  and  amorphous, 
e.\cept  in  the  uterus  during  ^station,  when 
may  be  observed  a  very  fine  strintion  which  is 
perhafis  related  to  the  new  function  which  tho 
uterus  presents,  the  ijuicl:  movement  ucecaniry

do  not  contain  nucleoli.  The  cells  are  so  united  as  to  form  fasciculi,  or 
membranes. 

According  to  moat  histologista  these  muscular  cells  are  derived  directly 
from  finbryonic  cells,  the  protoplasm  of  which  experiences  successive 
changes  and  is  transformed  into  muscular  substance,  the  nucleus  becoming 
elongated  or  rod-«liupcd.

80  intimately  united  tJiat  their  limiw  cannot  bo  distinguished.  But  by 
irritatiun  they  become  swollen  aiul  separntcd  from  one  another. 

By  injections  of  gelatine  aud  nitrate  of  stiver,  the  eiiduthelial  layer  in 
place»  along  the  course  of  the  cnpillane»  ts  elevated,  without  the  injection 
passing  out  of  the  vessels.  The  cnpillurics  are  therefore  limited  at  their 
periphery.  But  a  double  contour  of  the  limiting  membrane  cannot  be 
seen,  ta  ttiat  the  démonstration  of  a  true  memhraue  U[K>u  which  the  epi-

This  view  is  founded  u)>oii  the  imposa ibility  of  i.iolatînn  the  capillaries 
when  they  are  not  surrounded  by  a  lymphatic  sheath.  This  endothelium 
is  continuous  with  that  of  the  aricriea  and  veins  without  any  Itue  of 
demarcation.

Ben  lictneeii  the  cells  spacea  or  atomata,  which  esUiblL^h  a  dirocc  com- 
'^unication  between  tbe  serous  cavities  and  lymphatic  canals.  The  serous 
cavities,  the  lymphatic  vessels,  and  lymrh  spaces  of  tbe  connective  tissue, 
therefore,  belong;  to  the  same  system.  The  lai^r  lymphatic  vessels  bave 
a  much  more  complex  structure,  resembling  that  of  veins  of  the  same 
calibre. 

GlnttdtiUir  rfithfUum,  the  cell*  of  which  may  be  pavement. cylindrical, 
in  the  form  of  pyramiiU,  etc.,  also  uiidiTgOM  a  constiuit evolution.  Thus 
in  tlie  glands  of  the  stomach,  the  cells,  primarily  cylindrical,  become  spheri- 
cal, filled  with  juices,  fall  into  the  lumen  of  the  glands,  and  are  destroyed 
while  discharging  their  contents.  Colostrum  cells  are  nothiti;;  more  than 
desipiamated  cells  of  tlie  mammary  acini,  and  when  they  are  not  found 
in  milk  it  is  because  they  have  been  destroyed  and  their  fat  sot  free  in 
the  fluid.  Some  cells  are  not  destroyed,  but  simply  empty  into  the  gland 
their  product  of  secretion.  Thia  takes  place  in  the  dands  of  làeberkUhn. 
The  cells  in  plands  are  planted  upon  a  limitin;;,  homogeneous,  byaline 
layer,  which  does  not  appuar  to  l>e  formed  of  cells,  but  scorns  to  be  a 
condensed  layer  of  the  (turroiinding  connective  tissue.  The  slnicture  of 
this  layer  is  not  well  detenmm^d,  but  almast  always  Hat  nuclei  are  found 
in  it. 

The  different  varieties  of  glands  are:^ 

Ist.  Tubular;  that  is,  consisting  of  a  simple  tube,  so  that  the  secreting 
portion  of  ûie  gland  is  directly  continuous  with  ttie  excretory  duct;  tbey 
arc  rectilinear,  and  lined  by  cylindrical  epilbelium  (glands  of  Licbcr- 
kuhn,  of  tbe  stonuicb,  of  the  body  of  t!ie  uterus,  elc),  or  are  rolled  into 
the  shape  of  a  ball  uu<l  lined  by  puvi^oK-nt  epithelium  (sudori&c  glands, 
kidney). 

2d.  Acinous;  that  is,  conm^ng  of  culs-de.«ac,  varying;  in  numWr, 
which  0|K'n  into  nn  excretory  duet.  The  culs^le-Hac  and  excretory  duet 
are  lined  by  a  pavement  epithelium,  as  in  tbe  sebaceous  and  mammary 
glands:  or  the  culs-de<sac  are  lined  1iy  epithelial  cells  in  the  form  of  a 
pyramid,  while  the  duels  are  paved  by  a  non-laminated  cylindrical  cpi- 
tlieiiiim,  as  in  tlie  salivary  glands,  Itninner's  glands,  tracheal  and  laryn- 
geal glands,  and  tbe  pancreas.

by  Virchow  and  named  biemnloidin  crystals,  may  be  seen  in  the  nocmeed 
pnrtd.  Whenever  extnivasated  blood  escajicB  into  a  natural  or  artificial 
cavity,  it  undergoes  similar  a1terutioii«.  The  white  cor|>uwles  oflor  a

contain  u  few  fatty  granules,  and  the  nucleus  is  undistin^rnisliablcfrom  the

long  time.

escaped  from  the  adijKWC  cells  ;  tlicy  are  deprived  of  the  oxvfjen  and  water 
necessary  for  putrefaction.  The  inliltraloii  fat  gives  the  dry  gun ;j;n) nous 
parts  the  translucence  which  is  seen  upon  section,  while  the  exposed  stir- 
face  i»  brown. 

Humid  or  tnoiM  tfangrenf  superveneB  when  fluids  are  constantly  con- 
veyed to  the  nan,  as  in  gangrene  after  inflammation  or  obliteration  of 
tiie  veins.  \\  hen  the  parts  are  deep  and  cannot  dry,  the  gangrene  i:», 
perforce,  humid.  The  fat  is  reduced  to  granules,  but  it  cannot  infiltrate 
the  tissues  which  arc  filled  with  water.  :^o  long  ns  oxygen  is  not  sup- 
plied— OS  in  cerebral  softening  or  in  splenic  infarction — putrefaction  is 
not  possible.  It  takes  pince  very  quickly,  however,  on  the  surface  of  the 
body  or  in  the  lungs.  Two  phases  of  gangrene  slmuld  then  be  distin- 
gnislieil,  jtiorliHmli-H  and  putrtfa<ii-m.  Kxamplen  of  tlie  first  phase 
are  seen  in  deai)  emhryoK  which  have  remained  a  longer  or  shorter  lime 
in  the  uterus.  Some  of  these  are  almo^il  dry,  and,  alter  exposure  to  air, 
resist  putn- faction  much  better  than  any  other  tissue.  In  these  fuetnses 
it  is  often  still  i>osaible  to  recogniiso  some  of  the  elements  of  the  tissues. 
The  red  bloo<l  disks  arc  usually  destroyed.  While  corpuscles  may  still 
be  seen  in  the  vessels,  but  tiiey  have  undergone  the  caseous  change. 
Fatty  granules  and  black  melanie  granules  are  also  visible.  The  brain

preserved;  the  myvHn,  in  small  i}UHniity  at  lliis  age,  has  merely  become 
preci))iuiled  as  fine  fatty  granules.  Tlie  muscular  fasciculi  of  the  trunk

to  be  choked  by  colloid  masses,  etc.  7he  liver  «nd  the  spleen  also  are 
smaller,  and  at  the  same  time  their  capsule  is  thickened.  The  miLscIcs 
of  old  people  uonstautly  present  a  certain  number  of  fasciculi  which  are 
atrophied  and  fatty  di-geucnilcd.

in  œdema  of  the  subcutaneous  eel  lulo-adi pose  tissue  coincident  with

Irritation  of  ccllulo-aili|>oi^e  tix^ue  idso  ends  in  the  disappearance  of  tlie

Accidental  atrophies  may  he  the  conseijueiico  of  compre.ision  of  the 
different  organs  and  tissues.  Thus  in  the  kidtiey.4,  when  the  {>elvis  is 
distended  into  a  cyst  bv  a  pyelitis,  a  hydro. nephrosis,  or  a  tumor,  the  i-enal

caused,  and  it  can  even  happen  that  there  may  result,  in  oon.'^eiinenee  of

The  raucous  or  colloid  matter  may  be  diffused  throughout  tbe  whole  cell,

Tbe  exaggerated  formation  of  colloii)  matter  reaches  its  greatest  in-

wîiich  ends  in  the  production  of  cysts  more  or  less  voluminous,  and  [loa-

may  be  seen  in  tlie  lymph  glandsof  old  people,  and  numbers  of  cysta  may 
arise,  comparable  to  the  follicles  of  the  thyroid  gland  in  the  adult.  In

tlie  fat  apparent  in  certain  elements  is  to  insnre  the  death  of  the  cell. 
Fatty  granules  arc  spherical  bodies  of  variable  eizo,  highly  rcfractivo,

The  more  important  crystalis  of  cholealerino  present  the  form  of  extremely 
thin  rhomhoidal  plates  (see  lig.  -26  ).  The  latter  crystals  color  red  under 
the  action  of  concentrated  sulphuric  acid,  awl  blue  if  they  have  been

surcharged  with  fat,  to  such  a  degree  tiiat  the  liver 
appears  to  be  the  magazine  of  fat  intended  for  the

The  physiological  pigmcntatiou  of  cells  hy  the  coloring  matter  of  tlio 
blood  id  easily  seen  in  the  spleou.  Kkuients  containing  red.  yellow,  or 
black  pigment  occur  nonnnUy  in  tlio  splenic  pulp.  'Ilie  coloring  matter

«mall  mianlity  phy!*i(ilftgicJilly  in  the  liwpatic  ri-lU,  aWo  prubiibly  c"nie* 
from  the  coloring  matter  of  the  red  blood  disks  which  are  destroyed  in 
the  liver  hy  the  biliary  acids.  The  formation  of  the  corpus  lutoiim  in  tiie 
ofary  after  the  discbarge  of  the  ovule  and  the  hemorrhajje  into  the 
(iraatian  follicle,  is  an  example  of  the  production  of  red  pigment  which 
mav  later  change  lo  black,  when  the  body  usually  appears  as  a  small 
alatc-colorcd  cicatrix.  Whenever  blood  i»  cxtrarasated  the  connective 
tissue  cells,  the  epithelium,  and  usually  all  the  surrounding  cell  élé- 
ments arc  impregnated  hy  a  fluid  which  contains  hseinatin  in  solution — a

Pathologically,  ])igmeniation  was  firiit  carefully  studied  by  Virchow, 
à  pr'fji'i*  of  pulmonary  hemorrhage-i.  This  author  saw  that  thv  epithe- 
lial cell»  which  at  lirst  had  become  spherical  and  pigmented  by  a  colored 
Suid,  soon  showed  in  their  interior  yellow  or  red  granules,  which  after- 
wards became  more  and  more  dark  colored,  like  crystals  of  hrematoidin. 
From  this  observation  he  was  led  to  the  hypothesis  that  the  coloring 
matter  of  tlie  blood,  when  given  up  by  the  corpuscles,  first  infiltrates 
the  cells  as  a  colored  Suid.  lie  admitted,  however,  the  possibility  that 
colored  granules  formed  without  the  cells  may  subsequently  penetrate 
into  their  interior,  Hgrneiit  granule»  are  well  chanieterized  by  their 
color.  Crystal»  of  hjcmatoidin  are  rhomhohcdr»;,  of  a  dark  orange-red. 
In  certain  case»  their  dimensions  are  »o  great  that  their  presence  may  he 
appreciated  even  by  tlit!  naked  eye  :  at  other  times  it  reiguires  the  highest 
powers  of  the  oiicroiscopo  for  their  recognition.    (^Fig.  4U.)

H.  Caia'ABBOU»  IsFn-TiiATlox. — The  «ilt»  which  form  these  infiltra- 
tions are  tbe  carbonates  and  the  tribasio  phosphates  of  linte.  These 
mita  are  combined  in  calcircoits  deposits  everywhere,  except  in  the  oto- 
liths, which  ara  solely  compo«ed  of  carbonate  of  Unie,  Truc  osseona 
tissue  should  not  he  confounded  with  liwuea  infiltrati'd  with  Uino  salts. 
In  the  latter  there  i*  no  real  or  pontianent  union  wiih  any  princiftal,  for 
when  the  salt^  have  been  ramoved  by  acid  the  ori;^iita]  structure  of  the 
tiiwie  may  lie  perfectly  seen,  an<l  there  may  be  no  approitch  Ut  a  regular 
bony  tittsue.  The  processes  of  true  ossi6cation,  therefore,  essentially 
differ  from  those  of  cilcareous  infiltration.  In  the  latter,  tlie  calcareous 
salts  deposited  in  the  tissues  are  seen  as  isolated  granules,  as  sphenitos 
witli  concentric  layers,  or  in  the  form  of  a  genuine  pctrifaclion.  'Ilio 
granules  are  round  or  angntar  iind  highly  refractive.  When  they  are 
minute  and  in  large  uinnbors,  they  cause  a  considerable  opacity  ;  on  tbe 
contniry,  when  a  eomplcio  petrifaction  has  occiirrad,  tlio  tissue  appears 
semi-transparent,  like  araj^oiiite.  In  the  lattercasc,  when  a  thin  lamella 
u  polislied  and  placed  under  the  microscope,  the  tiM^tic  is  seen  to  be  trans* 
parant  and  yellowish,  and  lacunar  openings  and  gr.-inules  may  be  dunion- 
strated  therein.  'Ilie  oiienin;^  are  the  sf^incos  whieh  existed  in  the  primi- 
tive structure.  All  acids  mora  or  less  completely  di»tolve  tbe  calcareous 
«alts  while  setting  free  bubbles  of  carbonic  acid. 

Pbyaiologically,  in  tbe  first  phase  of  ossification  calcareous  granulc-s 

are  seen  in  the  ground  substance  of  cartilage  ;  concretions  or  calcarcoiu 

iberes  with  concentric  layers  are  found  in  tbe  choroid  plexus  of  the  adult, 

often  in  the  thymus  gland  during  its  retrogressive  state,  and  In  tbe 


méninge  of  the  brain  aivl  »|nnal  iDArrow  of  th«  aged  ;  petrifactions  Home- 
times  occur  in  llic  prnfound  layer  of  mliilt  cnrtîlage  in  rela^oii  witU  lh« 
<HKeo(ifl  tissue,  aiitl  in  tlie  coiital  and  lar^vnj^al  cartilagea  nf  the  a^çed. 
Never  doea  the  deposit  commence  in  the  cell.  Imt  alwavs  around  tlie  l.iHer 
in  the  intercellular  or  ground  subatance.  .Sub-ie-iuontly,  tlie  cclln  lliera- 
selves  may  become  invaded,  but  they  usuall.y  escape  for  a  rery  long 
time. 

['atholo^^cally, calcareous  granules  maybe  met  with  when  a  dead  part 
remains  for  a  lon;^  time  in  tb(>  midst  of  living  tissue.  An  vxtra  uti^rine 
abdominal  prtjinaiicy  of  twenty  yt-are'  standing,  old  iiifii rctions.  caseous 
massos.  especially  of  tlie  lymph  f;1iii>ds.  are  familiar  t- xnmplca.  Calcareous 
concretions  are  seen  aUn  in  the  «ecretion»  of  the  -^aliiTiry  glands,  the 
acinoui*  glaniU  of  tlic  pharynx, of  the  pancr«a8,thc  follicnlar  crypts  of  tli« 
ÎDtc«tinei«,  in  the  synovial  mombranvs,  as  well  a^  in  the  interior  of  all  cyets, 
particiitnrly  the  colloid  cysW  of  the  thyroid  gland  and  of  the  kidney».  In 
advanced  atageit  of  cbromc  iullammaùon,  eapecialty  in  endarteriti»,  ofViii 
calcareouH  gramiln»  or  petrilied  plnipics  are  to  be  aecn.  Tliin  melaaior- 
pbo»iii  supervenes  only  when  the  inflammatory  prooesa  has  spent  iW  force, 
or  when  the  circulation  of  the  Quids  is  much  impeded.  The  products  of 
chronic  inHammationB  of  the  seroiif  membranes  haro  a  pecidiar  tendency 
to  calcareous  incrustation*,  which  were  formerly  regarded  as  true  bone. 
In  chronic  myocarditis  the  muscular  walls  of  the  heart  sometimes  present 
concretions  of  the  same  nature.  Illood-elots.  wlierevcr  they  may  be.  may 
undergo  calcareous  iulîllnition.  i'hK-liolillw.  the  concretions  oiTcasionally 
found  iu  varice*,  have  siicli  an  origin.  In  old  age,  around  old  fractures, 
and  ill  the  neighborhood  of  chronic  arthritis,  the  tendons  and  even  the 
muâulea  are  sometimes  the  seat  of  a  calcareous  deposit  of  greater  or 
lesser  extent.  In  nearly  all  the  tumors  are  freiiuently  to  be  seen  caica- 
reous  intiltralions,  rehicli  should  always  bo  distinguished  from  true  03ei> 
(ications,  which  latter  are  rare  under  the  same  circumstanc«B. 

I,  Infiltrât II IN  of  the  Thatrs. — Tlic  presence  of  the  urates  in  the 
solid  stall.',  undcT  the  form  of  jtranule*  and  crystal»,  is  met  with  phyeio- 
logically  only  in  the  urine.  In  now-born  childn^n,  however,  very  often 
we  find  in  the  slrai;^ht  tubes  of  the  kidnvy*  amnrphou*  urates  colored 
brick-red  by  the  urinary  pigment,  and  vtMblc  to  the  naked  eye  iinder  th« 
form  of  minute  red  lines.  Here  tlie  .U>i>OBit  occurs  in  the  epithelial 
cells  of  the  kidney.  Under  the  microscope  the  urates  may  appear  as 
very  fine  granules  massed  together  as  a  cloud,  as  refracting  spherical 
grains,  or  under  the  form  of  needle-shaped  crystals.  The  base  may  be 
magneâia  or  lime,  but  it  is  usually  soda.  The  urates  arc  decomposed 
even  by  the  weakest  acids,  when  the  free  uric  acid  may  precipitate  and 
form  crystals  which  are  «t  first  rhombohedric,  but  which  often  soon 
assume  the  varied  form»  which  uric  acid  shows  by  reason  of  its  molecular 
dyssymmetry.  Uric  ucid  and  the  urates  may  concrete  and  form  calculi 
in  the  urinary  passage». 

lu  gout  the  urates,  under  the  form  of  granules  or  cryatals,  are  de- 
pociled  ID  the  cartilages,  the  bone»,  the  synovial  memhrannt,  the  tendons, 
the  skin,  and  the  kidneys,  [n  all  cases  the  dcpi)sit  first  fonns  in  the 
cells,  which  serve  as  centres  whence  radiate  the  free  cryataU.    The  latter

plaaia,  whicli  Virchow  regardeii  only  as  patliolojfical  conditions,  may 
exist  in  the  phrsiological  state,  aa  is  seen  for  example  in  ossiËcation. 

In  nbDormal  hj|)erj>l»sia  the  multiplication  of  the  colls  is  effected 
always  in  the  name  way:  the  nucleus  eireiis  ;  the  niiclcoluâ  becomes

instead  of  a  single  cell  two  or  more  cellular  elements.  Never  doe»  the

most  fremienlly,  on  the  contrary,  these  may  sionen  or  di&solve.  At  firet 
the  C4^11  elementâ  thus  formed  do  not  notably  ditler  in  appearance  from

Before  leaving  this  subject  perhaps  it  may  be  well  bo  reiterate  again  the 
ftenerai  law,  thai  the  method  of  formation  of  elements  of  pathological  new 
growths  is  identically  the  snmo  m  that  for  physiological  formations.

mass.  Ench  ciAl  then  excretes  around  it  cartilaginous  substance  in  order 
to  form  •  new  Cftpsiile.  Up  to  this  point,  the  irritation  has  chan^^cd  neither

latter,  capsules  may  be  seen,  still  closed,  tilled  with  embryonal  elements 
which  have  lost  the  property  of  forming  around  them  cartilsKiuouH  sub-

a  single  faaciculus  of  connective  tissue.  All  these  trabeculaj  are  covered 
with  a  single  layer  of  large  endothelial  cells  whose  form  and  constitution 
may  be  appreciated  after  the  employment  of  impregnation  )iy  nitrate  of

tSect.  III.— Artificial  Irritation  of  Vascular  Titsnw. 
O*»rou»  ti»me  ie  very  eaxily  studied  in  inflammation.     The  oaaeoaa 
fe^-culm  limit  space»  in  which  the  vascular  tissue,  tlic  marrow,  ts  the 
Hilt  rif  almost  every  nutritive  or  formn^ve  lesion. 
IiCt  us  suppose  an  artificial  irritation  of  a  short  bone,  or  the  extrcnuty 
of  A  long  one.  , 

There  is  al  lirat  a  formation  of  embryonal  tissue  at  tlie  ospemte  of  the 
subperiosteal  ineilullary  celU  and  "f  the  cells  contained  in  the  inodullary 
spaces.  Normally,  the  medullary  celU  are  free,  are  not  inclo^d  in  a 
fundamental  or  ground  substance.     Some  are  small  (medulla  cell»); 

E  others  are  lar;^,  with  one  or  many  ovoid  nuclei  (myéloplaxea  or  giant 
cells).  Jlesides  iheae,  tiiere  exist  large  adipnse  cells  and  fiuiform  or 
stellate  elements.  It  is  from  all  these  different  elements  that  the  «»• 
bryonal  cells  arc  derived. 
In  tlie  adipoi>«  vesicles  of  th?  irritated  bono  marrow,  the  nucleus  lîrat 
hypertrophies,  theu  divide:  the  swollen  proloplai>ni  surroumU  i^ach 
unclcuii;  at  tlie  same  time  the  fat  dlsappi^ars  and  is  replaced  by  an 
albumiuoiil  fluid.  These  new  elements  multiply  and  finally  completely 
fill  the  vesicle;  the»  ib*  membrane  ts  destroyed  or  ruptured  and  (he 
eoDtained  embryonal  cells  become  free. 

I'he  medulla  cells  a»nime  the  character  of  embryonal  cells,  to  which 
they  are  so  nearly  related,  anil  multiply.  If  the  irritation  continues, 
the  osseous  lamella-  adjacent  to  the  medullary  tissue  are  absorbed,  and 
each  bone  cell  falls  into  the  medullary  cavity.  Thus  the  medullary 
cavity  enlarges  and  is  filled  willi  embryonal  cells,  an<l  the  osseous  tra- 
bocala>  melt  awuy  under  the  process  of  absorption.  (Sec  fig.  48.) 

During  this  time  the  capillary  vessels  undergo  very  important  modifi- 
catioita.  The  cclU  which  form  their  walla  swell,  their  nuclei  become 
more  apparent,  so  tliat  on  transverso  aect'ion  one  caight  believe  Uio  walla 
to  be  maile  of  fusifonn  bodies  analogous  to  the  fibra-plastic  cells  of

and  very  apparent  (fig,  4i',  e}.     After  a  few  houra,  the  nucleus  and  the 

firotoplasm  divide,  whence  two  or  more  embryonal  colls  appear  in  the 
yniph  spaccg  of  the  tiseue,  arranged  into  clongtiled  islands  or  chiuns  of 
ccIIh,  pressed  a^aiuat  each  other,  and  limited  by  the  parallel  fibres.  la 
the  adipose  vesicles  the  )>ratoplasta  becomes  visible,  the  nucleus  divides  aa 
in  meilullnry  tissue,  and  the  fut  disappears.  By  the  continuance  of  tho 
proliferation  each  fat  vesicle  is  replaced  by  ft  little  nest  of  embryonal  cells 
(fig.  40,  e).  Proliferalion  of  adijiosc  cell»  is  not  effected  as  rapidly  as 
thai  of  ibe  coniMJCtivc-tissuc  corijuscles.  The  former  may  con*c<iuently 
often  be  seen  in  the  midst  of  embryonal  tissue  for  tiome  time  after  tlie 
commencement  of  inflammation. 

While  tbc  cellular  elements  are  tlic  ttieatro  of  the  preceding  changea,

tion of  the  iliH|x-desi>ç  of  the  element»  of  the  blood.     His  i^tatements  were 

overlooked.     ï^nVo^ueiilIy  Cohnhcim,  apparently  without  any  knowle<(go 

of  the  opinions  of  Waller,  inittitnted  a  sencs  of  experiment»,  mainly  upon 

the  come»  ami  mesentery  of  frog»,  which  tended   to  iMtahli»h  in  an 

indiihiliihle  manner  the  emigmtion  of  white  btood-vorpiL-^le^  from  the 

luuion  of  tlie  Wood  vessels,  and  to  explain  mippiimtion  by  their  eimai*  in 

immense  numbers  into  the  ti^ue  involved.     Oohnheim  commenced  at 

Erst  hy  curariztog  the  frog,  claiming  thai  enrara  had  no  action  upon  the 
1       fiirealation.     This  claim  must  be  denied,  for  the  poUon  determines  at 

Brat  a  contraction,  then  a  dilatation  of  the  small  arteries.  'I*his  jiro- 
I  cedure,  then,  is  not  entirely  free  from  a  first  cause  of  error.  The  abdo- 
I        minal  wall  was  incised,  a  loop  of  inlcHiine  withdrawn  very  gently  and 

spread  upon  a  gla»s  slide,  to  that  the  mesentery,  when  plac«d  under  the

an  hour  tn  an  hour  after  tlic  coiiiroeiicemenl  of  the  experitnent  the  vaina

rieH,  when  the  red  globulea  can  be  dUtitiKiiishod  tmà  even  counted  in 
their  passage  along  the  larger  vessels.     We  know  that  the  inner  sur- 
face of  the  small  veins  is  covered  bv  an  adhesive  layer  containin;:;  white 
globules  which  remain  more  or  loss  motionless.     In  întlainniatinn  these 
while  cells  become  more  numerous  utid  prewnt  ania-hdid  nuivements. 
While  repenting  these  expcrinicnts,  wo  have  been  struck  by  seeing  tbc 
aiuielioid  ]>rolonKftlioni<  producoii  only  on  one  «idc  of  the  globule.    The 
mcehAui^in  of  this  («cnliur  doforaiity  can  be  readily  olnerved  :  when  iho 
white  cor]niHcleit  remain  in  the  adhesive  layer,  tliev  fix  tbemselveii  u[)oaj 
the  wall  of  ihe  vessel,  while  the  flowing  blood  bends  them  and  lengtbenH 
them  out:  if  now,  under  the  action  of  ilic  circuialory  ntovoment,  thejl 
become  detached,  we  see  the  portion  which  waa  adherent  present  thd 
form  of  a  nipple  covered  wiih  spines.     These  conmselos  accumidato  in 
the  dilated  veins.     Up  to  this  point  we  have  ourselves  been  able  to  oo»-" 
firm  alt  tliese  phenomena.     Acconliiig  to  (,'ohnboim,  and  many  other 
acctimle  observers,  many  of  the  cells  finally  pass  through  the  walls  and 
escape  intii  the  snrroiniding  tissue. 

The  manlier  of  cscaçc  of  tlie  eorpuMclea  of  tlio  blood  is  still  doubtful, 
Cohnbeiui  believes  that  they  go  out  through  Rtomats  between  lli«  ondo- 
thelia.  lie  a.<-iimt1ates  the  remaining  tunics  of  the  vessel  to  conneotJvtJ 
tissue  in  which  there  are  networks  of  lymph  uhannels  and  spaces,  anj" 
lie  conceives  that  the  escaping  celU  work  their  way  along  these  until 
ttiey  pniïâ  bcjond  the  wall.  The  Siime  plienoniciia  aftpear  alao  in  the 
eajiiHorics. 

Tlie  red  ;;totiii]<-s  al^o  inny  i-i<ca]ie  from  the  vessels.    We  have  oh8erve<l| 
(he  passHgi-  iif  the  rod  disk»  thi-ou^h  the  wall*  of  UiK  capîllnries  in  the  web* 
of  the  frog's  foot.    Some  authors  consider  tiie  pbenonienun  to  ht;  physiolo- 
gical.   U  isafact  that  almost  all  Diamntifern^  have  roihli.sks  in  their  lyin|ihj 
Tesacls  connecting  the  lymphatic  mdiclea  and  the  lymph  glaiid!>.     Tbesal 
globules  have  very  prohaoly  escaped  from  the  blond  vessels.     The  red 
globules  which  have  escaped  from  the  bloodvessels  are  often  consirieted, 
mummillalod,  or  fra;.a"iented.    Their  color,  their  refraetion.  and  their  setisi* 
bility  to  reagents,  contribute  to  the  determination  of  their  nature.    Such 
altcrei)  globules  arc  found  in  most  intlanimatory  exudatjons. 

'nic  facts  advanced  by  Cohnheim  lio  not  conflict  in  any  manner  with 
those  which  we  have  desoribeti  à  fir^t/M»  uf  inflanmiation  of  cartilage, 
hone,  and  conneetive  tissue.     The  iht-ory  of  Cohnheim  does  not  appear  j 
to  us  to  apply  to  alterations  of  intlnmed  cartilage,  because,  among  othcr^ 
reasons,  the  phenomena  of  prolifi-raiion  theretii  take  place  within  the 
interior  of  each  capsule,  which,  so  far  as  we  know,  is  a  closed  cavity, 
Nevertheless,  Cohnheim  would  explain  the  suppuration  even  of  non-vas- 
cular tissues  by  a  migration  of  the  while  corpuscles,  taking  as  an  ex- 
ample the  cornea.     In  examining  the  inflamed  eomea  of  frogs  in  the 
moist  chamber  of  the  microscope,  Recklinghausen  saw  the  cells  of  the 
lymph  «[taces  increase  in  mnnher,  and  slonlv  move  along  the  canals 
from  one  apace  to  anotiier,  in  order  to  accumulate  as  embryonal  celts  orj 
pus  corpuscles  at  the  surface  of  the  cornea.  * 

ColiDheim  refieated  these  experiments,  and  fonncd  tlie  bypotbcais  that

irritation,  the  conif»  mny  Ipcc'une  inlillratcil  by  a  laff-e  iiiiniitity  of  fluid 
from  the  blooil.  TWi»  fluid,  li{ildin<|  in  ^uripennioii  the  coliiied  jariicVs 
of  aniline,  comes  in  contact  with  the  various  cells  of  tho  comea;  the 
granules  may  then  penetraic  them  directly.  Thus,  it  t»  ]>owil>le  to  set 
np,  in  ptac«  of  the  theory  of  Tohnheim,  the  hypothesis  of  the  direct  pene- 
tration of  tho  particles  of  aniline  into  pus  corpuscles  which  may  be  gencr- 
a«'d  in  the  cornea.  Witlioiu  wishing  to  deny  the  theory  «f  Colinhfim, 
we  hold  merely  that  his  exf>cnments  may  be  interpreted  by  another 
hypotlH-sis,  and  that  npon  a  «jueslion  so  important  it  is  well  to  wilhhoM 
a  positive  conclusion.  Moreover,  it  has  been  detnotistrated  that  in  irri-

had  been  obsen'ed  by  l>i:iUinj;er.  This  observation  waa  auKi«<|Ucntly 
made  by  at  least  seven  other  invest iga tors  before  Colmheim's  socslled 
discovery  in  18<[7  of  the  passage  through  the  walls  of  ihe  blood- 
vessels  of  the  white  corpuscles  of  the  bloo<l,  and  the  construction  of  his 
theory  of  inflammation  and  of  the  formation  of  pua.  Among  those  who 
have  confirmed  Çohnhoim's  investigations  by  observations  of  their  own, 
perhaps  Axel  Key  and  Wallis  have  made  the  most  important  studies. 
On  Ihe  uthvr  band,  the  most  competent  and  reUiiblc  observers  testify  in

TliiB  opinion  is  most  generally  adopted  to-day,  It  is  probable,  liowcvor, 
that  tliure  should  be  added  to  this  cau«c  the  fnvt  demonstrated  by  VaXov 
and  fft.  I'ierre,  that  tliu  eoiigeslcd  vowk-Is  contain  a  larger  proportion  of 
aru-rinl  binod,  t*  well  aa  ibc  fact  that  there  is  often  some  diffusion  into 
tlie  tisMucH  of  tlie  coloring  matlor  of  the  blood.  The  epitlieliiim  and 
eotmcctive-Usaue  celt»  of  the  hyjierivmio  part**  often  preMnt  a  color  at 
limt  yellowish  or  reddish,  and  occwioiuilly  contain  pilent  granules 
w'hioh  become  more  and  more  black.  The  latter  state  of  the  cells  is  one 
of  the  causes  of  the  slaty  color  of  cicatrices  of  serous  membranes. 

2.  Inflaiimatokv  Exf!'ATliiS3. — A.  Sefi'tiM  erudationa. — Tlie  exist- 
ence of  fluid  exudations  containing  only  dissolved  albumen  has  bee» 
assumed  rather  than  chemlcJiily  demonstrated.  In  reality,  these  fluubt 
almost  always  contain  variable  <iuantitice  of  fibrinogonous  matter,  of 
fibrin,  or  of  iDucus,  according  to  tlie  part  afiectcd.

case  of  white'  tivrellingii. 

C.  FiltriHous  exujittions  de  not  escape  from  the  rcssols  in  the  shape 
of  coagnlatod  fibrin.  Oenys  de  Commcrcy  believes  that  the  fibrinous 
eul>»t»iicc  exists  in  the  blood  at  fir^t  in  solution,  and  in  exudations  in  the 
state  of  dissolved  plasiuiii,  and  that  this  plasmtn  eougulatcs  into  librin 
under  tlie  influence  of  a  substance  acting  as  a  ferment.  Under  diRerenl 
terms,  .\lexander  Schmidt  hits  advanced  a  similar  idea,  lie  considers 
that  there  exists  a  substance  whteli  he  caW»  Jihrin";/cn  held  in  solution, 
but  which  jio^^eiise^  the  |>ro|ierty  of  coagulatiii;;  wlii>n  it  comes  into  con- 
tact and  combines  witli  another  albuminoid  subatauce  which  he  calls 

The  globulin  contained  in  the  red  blood  disks  is  a  6brino-plaatic  sub- 
stance, but  all  the  ti^isuea,  the  cells  in  particular,  contain  it  and  may 
conseouently  effect  the  coagulation  of  the  fibrinogeoous  substance. 

Ciider  the  influence  of  an  intense  inflammatory  congesdon,  the  fibrin- 
ogciious  matter  escapes  from  the  vessels  and  coagulates  by  uniting  with 
the  librino-plastic  substance  derived  from  the  cells,  'llie  coagulation 
takes  [iluce  suddenly  and  in  miccessive  hiycr»,  the  «xudat  in  contact 
with  the  tissues  alone  coagulating.  Kxiidatîons  in  closed  cavities,  for 
example  tlie  pleural,  may  almost  entirely  consist  of  coagulated  fibrin.  If 
the»e  exudations  are  drawn  olf,  however  serous  they  may  be,  they  soon 
coapilate,  from  contact  with  Hbrinoplastic  subntanoea.  Very  thick  layers 
of  6brtD  covering  the  thoracic  walls  are  thus  often  formed.  Schmidt 
assigns  to  the  fibrinogenous  substance  a  very  considerable  office  in  In- 
Sammation.

multiply.  These  phenomena  arc  the  same  aa  those  already  described

D.  CimtritotioK  or  ffealtnff  of  nVunds.— A  wounKl  may  Ueal  by  first 
or  second  or  even  by  the  thinl  intention.  Cicatrixatiou  consUts  essen- 
tially in  nil  caxes.  in  tbo  formation  between  the  lipa  of  the  wound  of  an 
embryonal  ùmmc  nhich  suliBct|iienlly  becomes  converted  into  adult  t4iMue. 
A  lolution  of  continuity  gives  rise  to  hcmorrbaj^c  from  the  divided  vessels, 
«rhieti  is  soon  arrested.  The  cxtravaeatcd  blood  coagulates  as  does  also 
the  blood  in  the  «aiùllaries  opening  upon  the  solution  of  continuity.  The 
coagulation  in  tlie  tatter  extend»  an  far  as  the  finit  collateral  captllanes. 
The  blood  conlinueti  to  circulât);  in  that  part  of  tlic  raitcular  net  which 
remains  permeable.  The  bonier^*  of  the  wonml  undergo  a  formative 
irritation  which  ends  in  the  filliiij;  up  of  the  lo«.i  of  subtitance  with  em- 
bryonal tissue.  The  permeable  capillaries  in  ^e  neighborhood  of  the 
cat  surface  present  the  changes  which  we  have  alreaily  indicated  for 
these  inHammationa,  proliferation  of  their  cells  and  sonening  of  their 
walls.  New  capillary  loops  coming  from  the  old  modified  veeaols  advance 
their  cmirexities  towapi  similar  loops  from  the  opposite  side.  If  tlioaur- 
faces  of  the  wound  are  maintained  in  contnct  a  vascular  communication  ts 
establiâliet)  by  the  union  of  loop»  from  op[>oi»itc  sides.  Then  the  solution 
of  continuity  is  filled  up  by  a  smalt  i[<iaiititr  of  embryonal  ti»(ue,  the 
cells  become  stellate,  anaatomnse  and  form  a  iieiworic;  the  cement  or 
intercellular  substance  aofl  at  first  soon  becomes  fibrillar  and  a»  résistant 
as  the  old  tissues.  Such  is  union  by  first  intention.  However  rapid  the 
union  may  bo,  it  is  not  so  simple  as  some  authors  have  thought. 

In  union  by  second  intention,  granulations  begin  to  vegetate  upon  the 
surfaces  which  cannot  be  kept  united.  Fi-om  the  sixth  to  the  eighth  day 
they  constitute  a  membrane  eomposcd  of  granulation  tissue,  the  vesseb 
of  one  granulation  anattomosing  with  those  of  the  ticighboring  bud.  As 
cicatrixation  progresses  the  embryonal  tissue  becomes  tninsformed  into 
connective  tissue,  as  in  tlie  previous  case.  Ilie  mode  of  healing  is  really 
the  same  in  the  two  cases,  only,  in  the  second,  cicatrization  is  slower,  and 
tlie  tifaue  may  experience  the  divers  accidents  incident  to  suppurating 
wounils. 

Union  by  third  intention  differs  from  the  preceding  only  in  the  depth  to 
which  tlie  tissues  are  divided,  in  the  greater  di.licuUv  and  xlowneM  of 
union.  Cicatrices  of  inHammatory  tissues  have  very  diverse  iasues.  In 
tlie  skin  the  cicatrix  is  composed  of  fibrous  tissue  ut  which  fat  vesicles 
600n  appear  in  the  deep  layers,  but  never  in  such  numbers  as  in  tlie 
nonnal  state,  moreover  the  fibrouit  tissue  is  always  very  dense.  The 
fibrous  and  elastic  tissucH  of  the  skin  arc  reformed  and  the  papillie  may 
be  more  or  les*  perfectly  rccongtnicted,  but  never  so  the  glands.  In

in  irritation  of  osseous  tiaaue,  when  very  frequently  hyperostoses  and 
exostoses  result.  Another  elill  more  important  law  has  relation  to  the

There  is  not  a  simple  absorptiou,  tor,  as  we  shall  ace  when  we  come  to

Iniitead  of  absorption  by  uecrosis  there  has  been,  on  tho  contrary,  a 
superabundant  formation  of  elements  which  first  dt-terniiiM;  the  mctamor-

irritation  whenever  these  elements  are  more  numerous  than  necessary  for 
the  reformation  of  the  primitive  tissue,  and  when  they  are  in  too  large 
numbers  relative  to  tho  nutritive  supply. 

In  irritations  atfectinK  the  parenchymatous  cells  in  the  so-called  paron>

Ilio  word  ttiiwr,  swelling,  from  the  moat  remote  anli'iuity  hiks  boon 
applied  in  medicinu  to  tlio  Dion  divorce  produutioi».  TUi»  dcËniliou 
undorwcnt  a  inodincation  at  the  hnnd:»  of  iht!  pthological  analocii»l«, 
who  applied  the  t«rra  only  to  every  abtiorninl  itiraefaclinn  which  could 
bo  demoitatrateil  at  the  autop^iy.  In  proportion  as  the  liUtoIogical  atmo* 
ture  of  tumors  iiaa  become  better  known,  the  group  of  tumora  has  been 
circuiQiwribed. 

The  following  is  tlie  definition  and  cltiasificatioD  which  ve  have 
adoptcil: — 

Wo  would  dcsi^ate  a  a  tumor  ei'ery  maim  miwtituteii  hy  a  new/nrma- 
tiim  (^nftphuMf  Ajikin'/  «  t^tuieni^tf  Vt  pi-mUl  or  tu  iniyreatr..  Tlii*  defini- 
^on  comprehends  two  term«  which  we  ought  to  analyie;  the  neoplasm, 
its  neruHtcnce  and  increa^te. 

Neopla^mii  are  subject  to  two  ireuer.il  lavrri.  The  first  was  announced 
by  J.  Mliller:  Tht  tiatua  whifh  J'oria*  a  lumar  hat  it»  tj/ite  in  a  tistue 
tf  tie  organism,  eliier  wA^n  tht  tatter  in  I'lt  an  emhri/oiutl  ef>»Jitlttn  or 
in  a  ttate  of  eompUte  dtvfhpnunt.  'ITie  second  ia  from  Vircliow  :  The 
celtular  elernent»  of  ii  tumor  are  derived  fr^in  thu  pre-exi»tirt;/  ceU»  of  tht 
m-t/amem.  Vtrchow  ailds  that  theif  are  derived  from  (Ac  cellt  of  tke  eon- 
Jieetive  tifsue. 

[Ii#tolo<;ist8  to-dav  arc  inclined  to  admit  the  law  of  Militer.  The  Inw 
of  Virchow  i»  true  in  lt«  first  proposition,  hut  the  second  pro[iosilion  i* 
not  tenable,  for  the  ccIU  may  be  developed  irom  epithelial  or  other  eeltii- 
lar  elements. 

Tiie  word  nejiphnn,  which  we  have  made  use  of  in  the  definition  of 
lumors,  should  neither  include  effusions  such  a«  escape  into  cavities,  nor 
the  retained  products  of  secretion,  etc.,  which  Vircliow  wroiij^y,  a«  we 
think,  looks  upon  as  tumors. 

The  tefond  term  of  our  definition,  the  pergtatenee  and  inereate  of 
tumors,  oompletoly  separates  those  neoplasms  from  inllammaiious.  In 
the  latter,  wiien  the  neoplasm  forms  it  organtxes  and  reproducer  tiasue 
similar  to  that  whence  it  sprung,  or  it  disappears  little  by  Vutlo.  by  EOppU- 
ratioii  or  caseous  metamorphosis,  otc.  This  ia  a  fact  so  important  that 
.  W«  insist  upon  it.

It  is  not  known  that  tutDora  pOMteMi  nerves,  unleaa  they  may  be  consti-

cliflerent  parta  of  the  same  living  organism  with  a  common  centre.  This 
abeenoe  of  nencs  impressed  Schrceder  van  dcr  Kolk  and  prompted  him  to

Beet  II.— Clauificatton  and  Description  of  Tumora. 

The  lavr  of  Muller  suggcsta  to  us  a  classification  of  lumon.  Our  clusi- 
fication  will  he  bused  solely  upon  the  analogy  of  tumors  with  the  normal 
tisauea.  either  in  thoir  adult  or  embryonal  state.  Thus  we  will  admit 
thoao  which  are  Roalogous  to  cmbryoiul  tissue,  to  fibrous  tissue,  to  carti- 
la^nau.<i  tÎMue,  to  oss<^otu  Usstte.  etc.  \V«  will  employ,  as  often  iM  poaai-

following  group»  ;— 

FittiiT  tiBui-f. — It  comprehenda  ttimor»  whose  constitution  ia  analogous 
to  embryonal  tissue.     To  them  we  will  apply  the  «ord  Mritotta. 

Skcosi»  Gnori'. — It  includes  tumors  eon*lit«ted  by  a  tiMue.  the  type 
of  which  is  found  in  connective  tissue.  This  tissue  may  be  mucous,  the 
tumor  is  then  called  a  myxoma  ;  it  may  be  fibrous,  it  is  then  cilled  a 
fehroHUi  or  an  innoma:  it  may  be  adipose,  it  is  then  ejillod  a  liiioma.  In 
certain  eaikis  the  tissue  undergoes  a  liy|>ertrophic  al^erration,  which  mainly 
affecU  tliG  volume  and  number  of  its  cells,  this  is  mitmnoHM,  which  should

We  will  at  first  study  the  generic  characteristics  of  tumors  analogous  to 
embrvona!  tissue,  then  we  will  discuss  tlio  characters  wbicli  appertain 
particularly  to  i-iicU  itjiccies  and  variety. 

Syxoxvmr. — There  are  no  tumor!  which  have  rwcivcd  more  different 
denominations  than  the  sarcomata.  J.  Millier  ti-nned  ihcra  jil'ni-ul/rnmi- 
v'/id,  lichert  called  tli<>m  f!Ar"-/>/t«ft<T.  Ohas.  Kobin  thought  that  fibro- 
pla-<lic  tinnor^  tnhould  be  .teparativl  from  certain  ones  which  had,  with 
the  former,  numerous  atialogiesi,  hut  which  differed  hy  the  round  form  of 
their  celU  ;  ho  nam<-d  them  einf-rynylniitie  Imni'V».  Paget  gave  to  the 
fibro-iiiastic  tumors  the  name  of  reeurrin'/  fikrifid,  and  classed  with  ihem 
certain  tumors  having  a  structure  simitar  to  the  marrow  of  hones,  which 
he  named  mi/eliict  titimrs.  The  latter  were  called  by  Chaa.  Uobio 
tumor»  with  medulla  relit  and  tumor»  with  mi/éloplturt.  Finally,  Vtr- 
chow  separated  from  sarcoma  somi?  tumors  which,  till  then,  were  clasM. 
fied  with  them,  and  to  which  he  gave  the  name  of  glioma  and  pgammmna. 

DKFisrrtox. — We  define  earcomata  aw,  tutmr»  e«ttjitilut*d  fr_y  emftrt/-

tiMue  i»  transformed  into  fibrous  tissue,  the  spherical  cells  lengthen  and 
become  fusiform,  and  an  intercellular  amorphous  substance  is  formed. 
Tumors  presenting  an  analogous  constitution  are  »<trc'nn'ita.  If  sarco- 
matous tissue  has  its  tyjie  in  a  physiolo^iical  state  wc  should  find  it»  ana- 
logue also  in  a  pathological  condition  durin;^  inflammation.  In  cicatrizing 
granulation  tisane,  we  meet  with  all  the  phases  of  connective  tissue. 
Certain  sarcomata  have  a  similar  structure.  In  inflammatory  tissue 
arising  in  the  bony  marrow,  cells  like  those  of  the  bony  marrow  show

saTComa,  is  not  very  rigidly  dependent 
opon  its  seat;  thus,  sarcoma  aprin^ng  from

I  Okxkrai.  I>EScRipnox  OF  Sarcoma. — 
Vbc  eelh  orsareooia  include  iho  most  varied 
p)mtt.  Some  are  «pberical,  others  are  ir- 
regular, witli  nmltipte  proeeBMS,  which 
■omelimefi  anastomose.  They  possess  one 
or  more  larf^e  round  nuclei  ;  many  of  the 
latter  are  fitsifonn  (the  fibroplastic  dé- 
nient of  Leber!  ).     In  cranial  tumors  the 

cells  arc  often  flat  and  oxtrenifly  thin;  they  rrvi|uent1y  are  lar;;e  in 
n»  attd  pOMC'»  a  central  lenticular  nucleus  ;  aeen  in  profile  they  appear 
as  a  fibre,  showing  al  it«  «entre  a  lengthened  nucleus  (see  Psam- 
moma). 

We  «ee  tJien  that  iJie  minr|>liology  of  the  eelU  of  sarcoma  \»  very  com- 
plex ;  the  «ixe  of  the  elements  may  vary  from  .00-5  or  .0U4>  ram.  np  to  .00 
mm.  The  iiLnicture  of  these  cetU  is  very  simple.  They  po^t^em  one  or 
several  nuclei,  eitlier  spherical  or  oval,  varvin;;  in  aiie  from  ,00.'i  to  .0(13 
mm.,  and  in  number  u|i  to  fifiy.  The  nucleoli  arc  usually  shinin^  and 
small,  but  they  may  exceptionally  aci^uire  a  diameter  of  .OU.^  mm.  Nuclei 
are  particularly  numerous  in  the  large  giant  cells  or  royâoplaxes.  Around 
tlu'  Tiucleiis  exi-its  a  granular  substance.  Examined  m  a  neutral  medium 
llie  nuclei  are  always  disiinct.  but  when  examined  simply  tn  wau^r,  or  in 
wnit-r  »li);htly  acidulated  witli  iicetic  acid,  they  become  much  more  sharply 
defined.  These  celts  have  no  membrane.  In  certain  eases  the  albumi, 
noid  grannies  of  the  colls  so  arrange  tliemsclves  as  to  produce  an  appear- 
ance of  Biriation.  As  in  embryonal  li.<4ue,  the  cells  of  sareoma  are  very 
sensible  to  the  action  of  reagents.  Ilccaudc  of  tlieir  friability,  when  the 
surface  of  fresh  tumor*  is  «craped,  the  elements  are  often  ruptured  and 
thfi  nuclei  set  free.     It  is  tliin  presence  of  free  nuclei  in  the  scrapings

and  w  the  vessels,  which  furnish  distinctive  characlera.  TTie  cells  are 
placed  close  together,  they  are  in  contact  or  are  scparatctl  only  by  an 
extremely  small  amoimt  of  int«Kellular  or  comcm  substance,  «rbich  is 
amorphous  and  very  soft  or,  perhaps,  indistinctly  fibrillar.  BloodrcsseU 
always  exist  in  ;;rcat  numbers  in  sarcoma  ;  they  are  in  direct  relation 
vich  the  cells,  or  thi.-y  ar«>  surroundt-d  by  fasciculated  connective  tiitstie, 
as  is  occasionally  tbc  case  with  some  of  Ùie  lar^  vcwvls.  (Seefij^.  r»7.) 
The  bloodvncMls  are  not  rcj^darly  di4]>o«ed.  Their  arranf^meni,  and 
tlio  Mrucluro  of  their  wall»  are  very  similar  to  thoite  of  iiiSamnwtory 
tlisuo.  They  arc,  therefore,  <lifficult  to  separate  from  the  mass  of  the 
tumor.  When,  after  Imving  hardened  one  of  thctie  tumors,  tliin  sections 
are  made,  tlie  lumen  of  the  veHselii  h  seen  to  be  limited  hy  round  or 
fusiform  celU.  but  rarely  does  one  discover  proper  walU  appertaining  to 
these  blood  channels.  This  is  an  esscnlial  point,  for  joined  to  the  ccnenil 
disposition  of  the  elements  it  distinguishes  sarcoma,  and  explains  the 
rupture  of  the  blood vt-asflls,  the  extravasations,  and  the  blood  cysts  ob- 
served in  these  tumors.

famish  a  basis  for  subdivisions.  Moreover,  in  accordance  with  the  dimen- 
sioi»  of  the  cells,  the  sarcomata  should  he  separated  into  small-colled  and 
large-celled,  a  distinction  which  is  most  useful,  not  only  bocaux  the  sixo

it  has  a  special  bearing  upon  the  prognosis,]

iniLHt  not  only  demonstrate  the  presence  of  certain  cell  forms,  but  we 
should  also  take  account  of  the  relative  proportion  in  which  they  are 
found.  The  intercellular  substance  is  sometimes  semi-Buid,  in  this  case 
the  cells  are  generally  round,  at  other  limes  it  is  solid,  the  cells  may 
then,  from  mutual  pressure,  assume  varied  forms.  If  the  cells  are  com- 
preaaed  laterally  in  every  direction,  tliey  become  fuwform  :  if  they  arc 
compressed  in  a  single  direction  they  are  fattened.  Upon  the  fonigoing

^^^ttKFixiTioK. — Myxoma  is  a  tamor  formed  of  mucous  tissue.  Iw  defi- 
nition is  involveil  in  that  of  mucous  tissue.  This  tissue  forms  the  umbilical 
conl  ;  it  persists  aficr  birth  in  the  vitruoiis  humor  of  tlie  eye,  but  in  the 
embryo  it  is  met  «itli  in  varioui»  parts  of  tbe  body,  Mucous  tissue  in 
the  embryo  u  observed  as  ono  of  the  first  pliascs  of  development  of  the 
eniliryonal  into  fibrous  and  ndipoge  tissue.  The  tumors  constituied  l>y 
it  «ttjrfit,  therefore,  to  hy  described  between  lliose  foriiK'd  of  embryonal 
tissue  and  those  coiwtitiiteil  hy  fihrouA  timtue. 

I'liywologically,  miicoui»  liniwe  presents  two  forms:  l«t.  Round  «ells 
isolated  in  the  midatof  a  mucous  intercelhilar  suhftanoo;  '2d.  Stellate 
and  auastomodiiig  cells,  suajicnded  in  a  similar  intercelliilar  aubstaiKe. 
It  b  rare  that  myxoma  prcseota  one  of  these  two  forms  alone. 

Dfi^cRiPTiux  OK  My^uua. — Myxomata  are  trambling,  gelatiniform 
tumors  permeated  by  vsssels  which  are  readily  seen  and  isolated;  when 
one  scrapes  them,  no  milky  juice  is  obtained,  but,  on  the  contrary,  a  fluid 
ùrailar  in  appearance  to  a  solution  of  ;(um  arabic.  In  this  fluid,  rod 
Mood  disks  which  have  been  forced  from  the  torn  vessels  are  seen,  to- 
gether with  cells  of  various  forms,  round,  angnlar,  fusiform,  sometimes 
possessing;  proceases.  The  cells  may  contain  one  or  more  nuclei;  they 
are  pale,  and  their  contours  are  not  dis-

'foetus  and  of  the  Dcw.bom  child. 

MyxotuHta  occur  by  préférence  în  locationg  vrhcro  cellulo-iidipoec  tiiMno 
exista;  they  are  frcijuent  in  the  subcutaneous  tissue  nnd  in  the  miiscl«8. 
Ill  nerves,  they  are  olWii  multiple,  developing  from  point  to  point  along 
llic  Muntc  of  A  poripbeml  nerve.  Ascending  along  bucU  a  nerve,  tliey 
mav  even  reach  tlie  crauial  cavity. 

ft  I»  reraarlcnblo  to  note  the  power  of  resistance  which  the  peripheral 
nerv«9  offer  tn  the  compression  and  invit-tion  of  these  tumora.  The  nerve 
tubes  usually  uwlerg^o  no  appreciable  nucrilivc  alteration.  In  tlie  brain 
myxomiita  often  form  greenish  ttiniom.  The  various  glands  may  also  be 
their  seat.  They  are  occasionallv  fotiud  under  the  [«eriosteum,  and  are 
met  with  also  in  the  bones,  UBoslly  in  the  short  bones,  where  Uiey  are 
generally  conneuted  witli  the  periosteum.  In  the  skin  tlioy  may  often 
assnme  the  papillary  form. 

Anatomical  Diahxosis  ok  >1v.\(]JIA. — The  differential  diagnosis  ia 
very  difficult  only  when  we  attempt  to  determine  whether  a  tumor  is  a 
«arcoma  with  mucous motamorphosis,  or  a  myxoma  with  islands  of  embry- 
onal tissue.  We  may  ho  guided  by  tho  fact  that  in  parts  of  a  sarcotna 
which  have  suffered  colloid  metamorphosis,  the  cells  are  destroyetl  :  in 
the  remainder  of  tbe  sarcomatous  tumor  the  proper  «tnictiirc  can  l>u 
recognizcil.  The  presence  of  elastic  fibres  or  of  genuine  adipose  colls 
immediately  suggests  a  myxoma. 

pRO«  XÛ8I3  OF  Myxoma  . — Myxomaia  are  generally  non-malignant.  En. 
tirely  removed,  they  very  rarely  return,  Thoy  almost  never  cause  second- 
ary  formations,  except  in  the  case  of  multiple  myxoma  of  nerves.  When 
inwmplotcly  removed,  they  redevelop  with  a  new  vigor,  like  every  tumor 
irritiiied  by  surgical  interference  which  is  not  effectual.  Mysoma  may 
increase  in  sixo  at  tbe  expense  of  the  neighboring  connective  ti)^ue  which 
has  first  become  embryonal,  or  it  may  enlarge  by  the  proliferation  of  iU 
own  proper  nin.ts.  Virchow  has  several  tim«s  seen  these  tumors  form 
mvtaxtatic  formation. 

It  i*  probable  that  their  gravity  or  Ijoiiignaiicy  t*  pmportional  respect- 
ively to  tlie  amount  of  embryonal  ti.'Mue  and  of  elastic  or  adipose  tissue 
which  they  contain.

DiacuiITlox  OF  FliiROUA. — Fibromata  are  tumors  which  are  dry,  hard, 
firm,  and  pearly,  pink,  or  white.  When  they  are  scra]>ed  with  a  razor,  the 
edge  of  tho  instrument  detaches  small  distinct  fragments.  In  a  thin  sec- 
tion of  a  fibroma,  one  will  see  bundles  of  fibres  which  intercross  in  every 
dirvction,  as  in  the  skin;  some  of  the  fasciculi  will  ho  seen  lenfTlhwise, 
others  in  cru«s-»ociiuu,  still  others  obliijucly.  It  will  be  impos«iMf  to 
mi4cou:<true  ihi»  disposition,  cspucintly  if  the  sections  are  colored  «lith 
ciirmine  and  treated  with  kcetic  acid.  One  will  then  sec  very  distioclly 
ft  network  of  plusinslic  cells  itmon<;  the  bands  of  fibrous  tissue.  ThcsQ 
buudft  are  t»  bo  di:<tiuguiMlicd  from  bundles  of  spindlc-cells  or  smontit 
inii:«cular  tiiMue  by  the  fadt  that  the  nuclei  of  the  fibres  «re  not  in  their 
interior,  but  are  up<jn  them. 

(«enerally  there  are  no  el».«tic  fibres  in  this  tissue,  and  this  is  one  im.

in  those  parts  of  Uie  tumor  whicli  po^ess  a  loose  connective  tissue,  and

SY:tONV)itt. — Cruveilhier  ha»  projiosed  the  vonl  atiipoma.  When  the 
ponwiilciico  of  tliG  tumor  was  lirnt  ami  h»nl,  it  wu  formerly  cullcil  a 
itatmna.     Cruveilhier  named  lUe  Utter  adifo-jitirmna. 

I)KnsiTl"N", — 'Hie  definition  of  lipoma  ia  based  upon  the  cellulo-adipose 
sue  which  constitutes  it. 

We  «lo  not  rcco^ixe  as  a  lipoma  the  masses  of  «dïpoM  tissue  whicb 
tplacc  an  atrophied  or^n,  nor  do  wc  tldnk  of  lipoout  when  conjùdcring 
lio  proMnco  of  a  large  ijuatitity  of  fat  lu  the  omentum  or  other  parts  in 
IpcrsotM  with  an  cxotigenited  corpulency.  The  name  should  be  limited  to 
ttbnormal  ui  reunite  riU-d  ma««cs  of  udipOMc  ttMue  baring,  to  a  curtain  ex- 
rti'nt,  a  vitality  imtcji^rn'U'nt  of  the  mst  of  thf  or;:ttni*in.  Tlii*  iitilcpHtid- 
lent  viliiUty  î*  dcuioiwtrnk-d  by  tbc  fact  that  a  piTMon  curryhig  one  of  ilieu 
amors  may  become  emaciAted  without  seeing  hin  tumor  dimiuisb  in  volume. 

DR6rRiprio:i  OP  Lipoma. — In  the  phyMolo^cal  «tate,  tlio  adipose  ves- 
uU  are  collected  together  in  limited  masses  or  lobulea.  These  lobules 
are  also  met  with  in  lipoma.  They  contain  very  large  adipose  celU, 
«hicb  are  aarrounded  by  an  enveloping  membrane  ;  the  nucleus  of  these 
transformed  conocctive-tissue  colls  is  very  distinct.  Both  the  lobules  and 
the  cells  arc  much  larger  than  in  the  norma!  suito. 

The  naked-eye  aspect  of  lipoma  perfectly  resembles  that  of  tbc  aub- 
eutaneous  adipose  ti««ue.     lin  pceuiiar  struc- 
tttro  gives  it  n  soflnrss  and  false  fluctuation 
which  is  characteristic. 

The  tiie  of  li{>omat«  is  variable  ;  Mmelimes 
the  tninors  ar«  of  olo^aal  <lim«n«ion:«. 

]n  yV.nit,  these  growlha  are  lobulntcii  and 
have  eitJier  diffuse  or  very  sharply  liraite'i 
boriera.  'llicy  often  form  poîyjioifi  elevaitonit, 
and  may  aometimea  hare  a  pedicle.  They 
nay  be  single  or  multiple. 

Concerning  their  location,  lipomata  are  fre- 
quently obaeri'cd  in  the  ar«olar  tissue  of  the 
elcin.  They  bare  bucn  seen  in  the  mucous 
membrane.  Tpon  serous  rocmbmnes,  adipose 
|)olypi  may  exist  in  tlie  nonnal  stole;  such  are  the  epiploic  appendages 
of  the  large  int^stinv  and  the  fringes  of  articular  synovial  niembrsnes. 
Tkeao  may  be  the  starting  point  of  lipoma. 

Lipomata  may  be  found  in  niu^ruhr  tissue.  Here  the  miiMular  fasci- 
culi remain  normal,  wbteh  i»  not  m  of  any  Mher  new  formations  Heated 
in  muscular  tissue.     Lipomata  of  bones  are  rare.

ti.  Oaityr*nf  is  possible  in  lipoma,  and  is  most  trc<iiient1y  seen  in  morbid 
masses  arising  from  the  pcritonoum  or  synovial  memhrane.  e.  Calmr^au» 
inHltratifti  may  occur.  </.  The  lipoma  may  inflame,  in  which  cusc  emhry- 
onnl  tissue  is  fonned.  the  fat  of  the  adipose  vesicles  is  partially  abftorbed, 
whilst  the  tumor  hecomea  harder. 

Dkvki,i)p«kst  of  Lipoma. — Since  it  is  in  the  plasmatic  cells  (connective- 
tissue  corpuscles),  whether  Ihcy  are  new  I  y -formed  or  pre-existent,  that  the 
fat  first  appears,  they  may  be  considered  to  be  the  starting-point  of  the 
morbid  growth. 

PUOONOSI*  OF  LiPuiiA — These  tumors  are  grave  only  on  account  of 
the  volume  which  thev  rnny  altuin,  tho  iiitiammatory  accidents  which  they 
may  determine,  and  by  reason  of  their  location.

DErisiTl'JX, — The  word  carcinoma,  employed  at  first  in  Germanv  in 
the  same  vague  sense  as  cancer,  has  of  late  received  a  more  precise  defi- 
nition, ba«od  upon  histological  structure.  Nevertheless,  it  has  not  yet 
been  sufliciently  defined,  for  to.day  many  of  the  German  pathological 
anatomists  do  not  consider  carcinoma  and  epithelioma  as  absolutely

pressure,  exerted  regulnrly  in  nil  ilîrections  from  the  centre  of  the  nlvc- 
c]\ti,  is  tho  cause  of  the  sphcricitl  or  rounded  form  of  the  alveuli.  (^Fij;.

Ill  carcinoma  of  the  mamma  the  adipose  tisAUois  preserved:  the  tumor 
((TOtTS  at  the  expense  of  the  connective- 1  issue  tnthccul»;  ivhich  separate 
the  lobules  of  adipoito  vesicles,  while  tho  latter  for  n  long  time  rctuaio 
intact  in  the  midst  of  the  nxjrhid  mass.  These  islaniU  of  fat,  an>;ular 
and  dis.4«iiiinatcd  irregularly  over  the  section  of  n  tumor,  have  euaM«d 
lu  miiiiy  a  time  to  form,  hy  the  naked  eye  vxamiiiiuion,  an  opinion 
which  lias  always  heen  verified  hy  the  microscope. 

At  the  itame  time  that  these  plieiiomenn  arc  transpiring  in  the  fibroux 
trahecidie,  the  epitiicliiim  of  uniue  of  the  canals  and  acini  proliferates, 
on  account  of  an  adjacent  irritatioiV.  Tho  acini  become  dtntended  with 
cells,  and  hypertropliied  to  such  an  extent  that  one  mi;^ht  be  ioclined 
to  believe  in  a  direct  relation  between  the  proliferation  of  the  cells  of 
the  epithelium  and  the  development  of  carcinoma. 

It  has  even  been  claimed  that  a  carcinoma  is  a  new  gland  destined  to 
«liminalc  noxious  clémente  from  the  organism,  just  m  the  kidney  elimin- 
ates uri-a.  The  faUily  of  tlii*  conception  is  demonstrated  by  the  fact 
that,  instead  of  a  thorough  ablation  of  the  morbid  ma»s  producing  an 
intoxication,  it  is  the  only  remedy  which  offers  even  a  small  degree  of 
safety  to  the  patieni. 

It  is  upon  the  existence  of  this  now  epithelial  tissue  in  the  acini  and 
j^tactuphorous  canals  of  mammie  which  are  the  seat  of  carcinoma,  that 
is  founded  «hat  analog*  may  exist  between  the  tatter  and  tho  glandular 
syttem.  The  force  of  this  analogy  is  dostroyvd  by  the  proocas  of  de- 
velopment which  wv  liave  related.  In  epithelioma,  on  the  contrary,  we 
never  see  epithelial  tij«uc  developed  in  the  inu^rior  of  lymph  simce:',  but 
un  embryoual  tixsue  in  the  neighborhood  of  pre-cxiittent  epithelial  ti>^«ue. 
pWhat  oharaoterines  carcinoma  is  it»  development  in  the  iyuiph  space»  of 
the  connective  tissue,  and  the  mammary  gland  does  not  escajie  this  rule. 

[.\l  the  present  time  most  patJialogiats,  and  es|)ecially  ibe  (ienuau,  are 
inclined  to  consider  carcinoma  as  of  glandular  or  epithelial  origin  rather 
tlian  as  developing  from  the  celUof  the  connective  tissue.  In  support  of 
the  fonncr  view,  {(indtteisch  says,  '*  the  majority  of  carcinomata  proceed 
primarilv  either  from  the  epithelial  clad  surface  of  the  body,  from  the 
skill  nuit  mucous  membrune,  or  from  secreting  glands.  They  depend 
upon  an  abnormal  growth  of  the  epithelial  tis.'tne."  liillroth,  in  his  work 
on  "  .Surgical  I'athology,"  "  maintains  a  strict  boundary  between  epitlio- 
liat  and  oonnective-ti».*He  cells,"  and  says,  "  true  cai-cimuna  have  a  forma- 
tion similar  to  that  of  true  epithelial  glanils  (not  tbc  lymphatic  glands), 
and  whose  cells  are  mostly  actual  derivatives  from  true  epithelium." 
This  writer  even  goej  so  far  as  U»  say  that  "  it  is  impossible  for  an  cpithe. 
liai  cancer  to  occur  primarily  in  a  hone  or  lymphatic  gland."  Waldcyer 
defines  carcinoma  aa  an  "atypical  epi^ettal  neoplasm."     Uirch-llirsch*

The  cells  of  carcinoma  have  of  themselves  nothing  cliai-acterislic.  It 
is  necessary  to  discover  the  presence  of  an  alveolar  stroma,  and  of 
clum[<s  of  cells  contained  therein.  It  is  not  from  the  study  of  scrapinfcs, 
or  of  the  Juice  of  carcinoma,  but  only  by  the  microscopic  oxunii nation  of

In  an  anatomical  point  of  view,  the  mosl  charactoristic  le«ioiM  of 
Sjpltilis  are  gummata.  Kvery  syphilitic  prodiict  is  not  a  gntnina  ;  most 
of  the  lesions  of  syphilis  present  no  analoniic^tl  iliâeronce  from  tlio^e 
cau?c<I  t>y  jiimple  inflammation.  The  lissions  deiermineil  in  connective  ii^nt 
by  hard  chancre,  do  not  esdeniially  differ  anatomically  from  those  wbic)) 
inflammation  produces  in  the  same  tissue.  The  celU  resomble  those  of 
iïrantdation  tissue:  they  are  embryonal,  round,  or  fusifom)  ;  some  corre- 
spond to  pun  corpuscles.  Thev  are  situated  in  the  midst  of  a  fundamental 
tubstancc,  nmorphou»  or  fibrillar  and  rm^itiint,  to  which  the  chancre  owes 
ibs  induration.  If  there  l>e  unytbin<;  which  may  ilisiin^nish  the  tissue  of

Whcu  imlumted  clmucre  heaU,  the  enibrvonal  tissue  which  form*  iu

period  of  consiiiulional  syphilis,  and  all  the  malformations  ol  the  second 
period,  consist  of  inflammatory  tissue  which  poaaosses  the  property  of 
refonnin;;  the  old  Itaeue,  and  which  may  leave  no  trace  behind.  This  ia 
00  more  true  of  lesions  in  the  skin  than  it  is  of  lesions  of  the  same  sta;;e 
in  the  deep  parts,  for  example,  in  the  parenchymatous  or>{iius,  the  peri-

df  embryonal  ttiiflue  takes  ]>lace  cither  throughout  the  or;;an  or  in  liiiiiicl 
pointa  which  are  to  Itecome  the  seal  of  the  tumor.  The  new  liiisue, 
which  accuraubiles  in  masse»,  become»  riitdled  with  numerous  vessels. 

Then  commences  the  •fdH-/  jihnrf  of  development  of  gummnla.  The 
cells  multiply,  ■limini'^h  in  siz^'.  are  compressed  against  each  other,  and 
then-  are  thus  prmloeed.  in  places,  little  nodules  or  irre;;uliir  islands,  in

In  Itone,  m  ivroliferation  of  the  cell»  of  the  marrow  occurs,  and  there 
Kflulta  an  embryonal  tissue  which  fills  the  o&ieoiu  canaU.  The  o&seoua 
trabecule  become  thinned  and  absorbed,  thus  giving  rise  to  latije  medul- 
lary spaces  in  which  the  gummatous  nodules  form,  by  the  same  manner 
of  growth  M  in  the  liver.

which  arc  always  hard,even  when  caseous,  from  infarctions  and  tubercles, 
which  frequently  soften  when  tbey  have  reached  the  caseous  condition. 

Gummatn  of  the  liver  which  have  exbted  for  ten  or  fifteen  years, 
often  exhibit  siut^ulsr  characters.  In  the  midst  of  the  liver  which  may 
have  preserved,  around  ihc  gumma,  ita  physiological  condition,  we  find 
angular  miU!H.vi  of  a  whidsli  or  yellonish-whitc  tissue,  which  are  very

important  link — jniliDonary  nhthisia — wait  alu>;;ether  taken  away. 

NieiDcycr  was  thu  first  clinical  t«acher  who  boldly  adopted  the  neir 
dootriiM}. 

The  exprrinwnlal  patholo-^iM  now  took  up  the  question.  Villemin  re- 
virH  tbc  old  opinion  of  tin:  inf^-.-tire  character  of  lubtTcuWi». 

\.oug  Iti'fore,  Itnhl  had  pronml^atod  t)i«  idea  that  miliary  ttiberculosU 
waa  a  "  rytsorjuion  iii*i!a«iî," 

Virvbow  ba^l  fiecn  ttiatinalmojl  all  casesof  acute  dinteminated  miliary 
tubi-rcutofiiii,  chee.iy  masMs  could  be  found  somewhere  in  the  body,  it^u- 
ally  a  cheesy  lymph  ^land. 

In  the  cxporiiuenial  inoculations,  therefore,  it  «as  interesting  to  note 
that  in  aome  cases  the  miliary  tubercles  wore  found  in  greatest  number 
around  a  choeay  focus,  as  if  ihv  latter  wore  the  point  of  inoculation  and 
resorption. 

In  this  way,  the  miliary  tubercle  tost  snmewbal  xtn  character  lu  a  pri- 
mary Icdon,  aind  iieemitd  r.ither  to  be  n  result  of  resorption  and  depend- 
ent upon  certain  anterior  condiliiins. 

Waldciiberg  demonHtrati^d  that  "  in  certain  animals"  tlie  manner  and 
matter  of  the  inoculation  are  of  no  conges  pie  nee.  Xexi.  Cohnheira  am! 
Fiaokcl  proved  that  "in  certain  animal*"  it  was  not  necessary  lo  inocu- 
late at  all,  and  that  the  formation  of  a  focus  of  suppurative  inflammation 
in  I  rabbit  or  <;uinca-pig  was  aufScicnt  to  render  the  animal  tuberculous. 

It  ))ecan>v  evident  that  the  species  of  animals  cmpkiycd  for  cxperi- 
taent  \»  a  mattvr  of  importance.  In  rabbits  and  gutnea-pi^,  any  focus 
of  irtinilent  iTiHiimmiition  is  vcrv  apt  to  puss  into  the  cheesy  condition. 

ft  seems  very  natunl.  therefore,  to  siippoçe  that  the  predisposition  of 
these  animal»  for  tuberculudis  is  a  conscipicncc  of  their  disposition  to 
cheesy  intlamniatio4i,  and  that  Ruch  aiiiuiaU  become  inoculaleit  from  their 
own  inflammatory  producli'. 

Thus  far  reached  the  experimentm  on  animals.  Their  principal  ohjeot 
was  to  demonstrate  the  infectioiut  nature  ol  liiherculoflis.  and  the  exisit-nc^J 
of  a  tuberculous  virus,  which,  like  -typhilis,  could  bo  transmiit«il  from  one 
person  to  another. 

A  TciT  remarkable  and  significant  fact  is  the  great  similnrity  between 
the  predisposition  of  "certain  animals"  for  tuberculosis,  and  the  almost 
exclusive  occurrence  of  tuberculosis  in  a  special  K<^uip  of  persons,  the 
«crofulous.  It  is  a  characteristic  of  the  constitutiounl  disease  called 
"scrofula,"'  that  all  the  iiiBammatory  processes  run  n  peculiar  courue.

The  consci  I  nonces  of  this  peculiar  anomalv  of  ve|ï«tsUoD  are  felt  in

undergo  a  granulo-falty  degeneration.  Their  detritua  is  {lartly  min;;led 
with  the  lymph  which  Hows  from  the  inHamed  tract  inlo  the  neighboring 
lyniphittic  glands,  and  [mrtly  t'ornis  an  element  in  the  secretion,  in  which

A  scrofuloui  cliild  ha:*  n  protracted  arthritis,  from  which  the  joint 
becomes  the  seat  of  a  .toftening  caseous  mass.  The  <letritus  in  contact 
with  the  deceased  synovial  membrane  is  absorbed.  There  results  from 
this  absorption  first  a  local  then  a  genera!  lulierculoiia. 

In  another  scrofnloos  child,  a  catarrhal  intlammation  of  the  small  inte^ 
tino  is  excited,  the  adenoid  tissue  of  the  mucous  membrane  becomes  infil 
tnit«d  with  cells,  which  subsec|ncntly  brcnk  down  and  are  absorbed  by 
the  lymphatics.  Then  there  are  produced  miliary  tubercles  atong  the

tuberculous. 

The  lymph  glands  in  luberoulosts,  as  in  tlie  case  of  malignant  ttimom, 
are  the  situations  in  which  the  new  growth  is  developed  in  tlie  clearest 
and  best  defined  manner. 

In  tubcrcnkais,  as  with  nuilignant  tumors,  the  snolling  and  ohstntclion 
of  the  lymphatics  may  cause  the  disease  to  remain  for  a  time  localized  in 
tlic  -{lands.  We  know  that  for  many  years  a  scrofulous  gland  niay 
remain  as  the  only  trace  of  youthful  scrofula.  It  ts  eminently  proper  in 
such  cases  to  extir]»te  such  a  ^Innd  in  order  to  prevent  the  gradual 
ial'cetion  of  the  whole  bo<ly  with  tubercles.]

are  surroiindcil  by  atn--xtremt'Iy  ^raall  amountof  pro. 
toplasm.  Tho  latter  are  embryonal  cells  undergoing 
atrophy.  The  reciprocal  arrangement  of  those  cells 
is  very  important  to  study.  In  euvh  submilinry 
granule  cnn  be  distinginshed  a  peripheral  proliferat- 
in;;  XQiic,  in  nhicli  cxlit  multinuclear  cells  (^unl 
cells)  and  fibro-plajttie  or  spindle-form  elements — a 
sone  sometimes  roncb  more  extensive  than  one  would 
suppose  at  first  view;  and  a  central  portjon  (fig.  ill) 
whcro  the  elements  become  closely  crowded,  and 
atrophied  in  proportion  as  the  centre  is  approached, 
anil  finish  by  failing  into  a  granular  detritus.  All 
these  clenicnl*i  acerete  around  them  a  granular  or 
lihrilliir  funditinental  jubslanee,  which  afc^^lutinatcs 
and  holds  them  very  firmly  united  together.  By  reu.^on  of  atrophy  and 
molecular  destruction  of  tlie  elements,  the  centre  of  the  small  nodule 
beoomcs  opaque  and  friable. 

The  vessels  of  the  centre  of  the  nodule  are  never  permeable.  This 
bloodK-asni'ss  is  the  cause  of  the  trau^lucency  of  the  tubetvle.  A»  ex- 
aniiriiiticiii  of  tht'se  vessels  shows  that  their  ohltieralion  is  effected  slowly. 
The  obliterated  vessels  betray  themselves  by  their  contour:  their 
lumen  i*  filled  by  a  coaguUim  of  granular  fibrin.  In  the  midst,  and 
«»j)ecially  at  the  border,  of  the  granular  contents  of  the  vessels  are  found 
white  bloi»d  corpuHclos  (A,  fig.  94),  elements  which  are  distinguisticd

Dkvklopmkst  of  TitMRRCLB. — Tubcrclo  i«  nlwaya  developed  in  the 
miiMt  of  an  emltryotial  tissuff  in  such  a  nmnnc^r  that  the  tuhcrcic  ^franule 
is  constantly  sarrouinled  by  a  »one  of  proliferation.  It  arises  from  the  con- 
nective tissue.  Thus,  in  the  Ucor,  the  granules  developed  iu  the  inter- 
lobular tissue  are  always  procoded  by  an  interstitial  hepatitis.  The 
development  of  tubercle  i^ranulcs  in  tlie  bonus  is  jireueiled  by  an  oslvitid. 
that  is  to  say,  by  tbo  formation  of  embryonal  tissue  in  the  nivdulUry 
cavities. 

Ontinol  tubcrwle  originate  from  epilhelial  cell-i  nx  well  »«  fwm  the  cou- 
neciive-tis$ue  element»  ?  We  nurselve»  have  obnerved  the  epitbvlial  colls 
contained  in  the  alveoli  of  the  thyroid  body  proliforatt-  ami  take  part  in 
th(.'  coMstiliiùoii  of  a  tubeanilou»  noiluli-. 

In  the  Umg,  the  tiibert-le  ;;ranule  eommonly  spring  from  the  inter- 
lobular, peribroncliial,  iLud  ini^r-alveolar  lïbrous  lis^ue.  Hut  ne  also 
m«ot  with  tubercles  wiiich  oucupy  the  interior  of  several  alveoli,  the 
clastic  septfl  of  which  arc  still  preserved,  In  such  a  case  the  embryonal 
tiiHuc  projects  from  the  alveolar  walls  into  the  interior  of  the  alveoli,  and 
it  is  possible  that  the  lining  V|iitholium  takes  part  in  the  formation  of  the 
new  «mhryonal  tiwue. 

[Accordin;;  to  Hiudfleisch  ami  nearly  ev«ry  other  writer,  it  is  froai  tlie 
fixed  eelU  of  the  vascular  connective  tissue  sy^ttem  that  the  miliary 
Mihercle  oriiiçinate^ — the  enilotheliura  of  the  hloodveitM-U  and  of  the 
lymphatics,  the  endothelium  of  the  serous  membranes,  and  the  fixed  con- 
nective-tissue corpuscles.  Many  of  the  more  recent  authors  rcKard  the 
formation  of  a  giant  cell  as  always  the  first  step.  On  the  other  liaml.as 
wc  have  already  seen,  numerous  mvestigators  not  only  fail  to  rccognixe  a 
dpccinl  si;;nificance  in  this  cell,  but  some  even  go  so  far  as  w  deny  the  pre- 
sence of  true  i^iaiit  ecll».  Kimltleisch  thinks  that  a  ;;iant  cell  is  DOthing 
more  than  an  cnlar;;»'!  endothelial  or  connective- tissue  cell,  with  an 
increased  number  of  nuclei;  and  he  has  found  them  constantly  and 
lias  oft",'»  useil  them  as  "jiijtn.postJt."  In  the  smaller  tubercles  he  has 
luualty  found  them  at  the  cenlre,  in  the  liir;;er  at  the  periphery  of  the 
crannies.  He  .states  that  uo  special  reliance  can  bo  placod  oo  them, 
for  they  occur  in  non-tube  renin  r  new  formations.  He  reganU  the 
greater  omentum  as  the  most  favorable  tissue  for  investigatimi.  Here  he 
roco'jniites  the  smallest  tubercle  as  a  nodular  swelling;  of  a  sin<^le  non- 
,  Yucular  connective- tissue  trabecula,  and  says  that  tliis  swelling  is  due

In  inlanders,  as  in  syphilis  and  tuberculosis,  «r«  observe  two  orders  of 
lesions:  the  one  purely  iiitlamtnatory,  the  other  constituting speoitic  ood- 
utea.  The  inllaramatory  lesions  in  this  affection  are  essentially  suppu- 
rative. 

The  now  formations  in  glanders  liavc  a  great  similarity  to  those  of 
tHhcrciilofti»,  t)f  spontaneous  orij;iii  in  the  horec,  glandciï  is  observed 
in  iiinn  only  after  contagion  from  the  former.

irautinjç  in  the  histolo)iicAl  details  which  would  enable  ua  to  give  a  coin- 
pietc  histological  account  of  it. 

Ilk  man,  as  in  the  horse,  the  disease  may  commence  by  a  primary 
tumor  and  ulcer,  which  are  soon  followed  by  Ivmphanpiis,  accompanied 
by  abscess  and  acute  or  chronic  suppuration,  ana  the  discbarge  of  a  serous 
pus. 

The  nodules  of  glanders,  in  the  horse,  arc  formt-d  of  itmall  cells  in  the 
midst  of  a  substance  vaguely  fibrillar;  the  cellulur  clcmciilK  atrophy  at

I  bone  trabecule  are  Bh^orl)ed  and  neighboring  medullary  cavities  are  opened 
into  each  olber,  so  that  a  large  cavity  is  formed  at  the  centre  of  which  a 
cartila>;inoiu  nodule  is  found.  The  latter  Increase»  in  sïsc  by  the  gni'luul 
inclusion  of  the  embryonal  cells  which  mirround  it.  Lnter,  th«  ndjoinin;* 
cmbrvonal  tissue  is  transformed  into  libruus  tissue,  and  thiw  U  ooiistitutcd 
a  veritable  perichondrium. 

Analogous  phenointna  arc  produced  when  the  enchondroma  spriug» 

from  connective  tissue.     Islands  of  embryonal  cclU  are  found;  at  the 

r  CxpCDsc  of  these  the  growth  of  eartîla;;;e  tolionA  its  Anlinary  ty(>e  of 

F  development.     In  certain  cases,  «ben  the  fnmiattve  movement  in  very 

slow,  the  fundamental  librouii  anbiitauce  of  the  coniiectivo  tissue  persi^Li  ; 

thns  libro-carlilage  is  formed. 

After  cartilagiiiou.t  islands  become  surrounded  by  a  perichondrium, 
their  increase  is  effected  by  a  multiplication  of  cartilage  cells  in  their 
interior.  The  elements  of  tbeac  islands  being  habitually  very  large, 
every  phase  of  this  multiplication  eau  lie  very  ejisily  followeil  in  ihern. 

From  their  very  beginning,  enc  hoi  id  ro  ma  ta  may  exhibit  nutritive  modi- 
6caltons.  Thus,  when  their  increase  is  rajiid,  ibeir  cells  may  become 
infiltrated  by  a  hyaline  sub.'ttance  not  well  determined,  yet  named  amyl* 
oid  by  Virchow,  becaniteihey  take  an  orange-yellow  color  in  a  very  feeble 
Bolntion  of  iodine. 

The  cells  of  enchondroma  contain  fat  when  the  tumor  îa  stationary. 
It  freijuently  happens  in  points  where  interstitial  growth  ia  very  marked 
that  the  celU  may  be  simply  infiltrated  with  amyloid  matter,  while  in 
olber  places  this  substance  is  replaced  by  fat  drops.  Fatty  «legeneratinn 
is  i^ometimes  observed  in  the  curtilage  cells  of  enchondroma,  when  com- 
plete destnietion  of  these  elements  is  the  result.  It  dctenniucs  an  arrest 
of  development  in  the  jmiiUs  alfeeted. 

When  ciilcari-ous  infiltration  takes  place,  it  almoijt  never  ocoura  at  the 
periphery  of  the  nodulos,  but  always  at  tlii^ir  centre.  U  may  present 
tvo  different  conditions,  according  as  it  accompanies  a  formative  move- 
ment analogous  to  ossification,  or  as  it  is  distinguished,  ou  the  contrary, 
by  a  calcification  which  invades,  at  the  Same  time,  all  the  secondary  cap- 
sules. The  latter  does  not  differ  from  the  calcareous  infiltration  to  which 
wc  have  previously  alluded. 

In  the  Qrst  case,  there  occurs  an  evolution  comparable  to  that  which 
take»  place  in  ossi6cation.  Tbo  chief  dilfercncc  is  that  in  enchondroma 
the  embryonal  marrow  may:  (a)  remain  in  the  embryonal  state;  (b) 
give  origin  to  fibrous  tissue;  (c^)  become  transformed  into  adipose  tissue,

tte  h«ro  some  of  the  history  of  rachitis,  whicb  we  will  describe  biter  in

lieculie  arc  situated  in  the  mid^t  of  a  fibrous  rïssiw  which  U  permeated 
ly  vessels,  and  iho  lymph  spaces  and  cauaU  of  this  tissue  freely  com- 
liiuiiiciktc  wilh  the  an;;ular  corpuscles  of  tbc  osteoid  trabeeulai. 
Fn>ra  l)ie  jirei:ediii;r,  an  osteoid  tumor  seems  to  be  coustitiited  by  trft- 
Veculie  of  variable  iliriicnsious  ami  form,  composed  of  a  rvfnictiii;^  homo- 
geneous or  vaguely  fibrillar  substance,  ofw-u  infiltrateil  with  «aîcarenii» 
,  Kranules,  and  containin<;  snpdar  corpuscles  ;  these  trabecule  are  nepuratcd 
iDy  fibrous  tissue,  in  which  course  the  vesKcls. 

This  osteoid  ti««ne,  however,  doc«  not  solely  compose  the  mass  of 

liamors  of  thin  name.    They  arc  almost  ulway!<  dotted  with  islands  of  car- 

jlttf!c,  aiid  infiltrated  in  places  with  calcareous  salt^.     The  cartila;;inous 

»reas  develop  in  the  inter  trabecular  fibrous  tissue,  and  in  this  case  alone 

ihouhl  the  name  otteoid  eHe/umdrfiina  be  applied  to  them. 

Calcareous  infiltration  in  some  part  of  ùiese  tumors  is  almost  the  rule, 
olated  calcareous  {granules  are  deposited  in  tb(>  fundamcntnl  substance 
jf  the  traljeculw;  ;  nevertheless,  the  corpusdes  surrounded  by  this  deposit 
lo  not  bceome  bone  corpuscles;  whether  there  be  only  cnlctireou*  infillru- 
ftion  or  complete  petrifaction,  these  eor|.usclcs  show  only  few  and  imper-

from  the  diaphjrses  of  long  bones  in  this,  that  the  Havei-sian  canals  in- 
stead of  bcin;;  parallel  bave  a  more  irregular  course. 

3</.  Sfonyif  '^(eoma. — These  osieomata  may  consist  of  spon^  or 
areolar  tissue.  The  medulln  fonnn  the  greater  part  of  the  tumor,  and 
bas  various  ch«mclers;  it  may  ho  i-inbryonal,  geluùnifurm,  fibrout,  or 
Jipose. 

SnAT  .\XD  DrvbTvOI'mkst. — Aoconlîn;;  to  their  place  of  development, 
we  dblinguish  two  large  ):ntu]i.'«  of  osteoninta.  The  first  comprises  lb 
irhich  are  atlached  to  boties;  tlie  second  those  which  arise  at  ft  distance 
from  them. 

The  Grst  loay  form  at  the  periphery  of  the  bone — exoattma;  or  io  its 
m  ed  id  lory  canity — tnoatogi». 

Ex(ï?T03ES. — At  the  surface  of  bones,  tbc  exostoses  prc«cnt  IlarcreiRQ 
Canuis  whicli  have  a  direction  <;enenitly  perpcmliculur  to  that  of  tb« 
Haversian  canals  of  tlic  old  bonc«.  The  periosteum  is  lifted  up  br  the 
tumor,  so  that  there  Is  a  perfect  continuity  between  tlio  bone  and  the 
cxoAto)(i#. 

It  is  ea*y  to  explain  the  perpendieularcourse  of  the  llavemian  canals. 
In  exostoses,  when  the  subpiTio:'t<-iil  tiiMue  ii«  trausfonuediulo  hone,  it  is 
the  periodical  vessels  nhicb  determine  the  direciion  of  the  Ilaversiao 
canals  and  the  dia{io»ition  of  tlie  lamella.  These  vesseU  are, as  we  know, 
perpendicular  to  the  surface  of  the  bone. 

Lxosloses  may  be  divided  into  tpîiJi^neaî  and  pareneh^tatou». 

The  fpiphi/iial  exostoses  may  be  met  with  in  all  the  bones.  On  the 
vault  of  the  cranium,  they  arc  generally  due  to  syphilis.  Upon  section, 
the  new  and  the  old  bone  are  ^en  to  bo  perfectly  distinct,  a  fact  which 
hcrctororv  has  escaped  pathological  anatotnista.

ve  did  not  subordinate  the  commonest  tissue  to  that  which  (fives  the 
tumor  its  special  characters.     The  muscular  tissue  is  of  new  formation 
in  these  tumors. 

In  oltl  men  the  prr^tate  is  often  the  seat  of  a  new  formation  of  smooth 
mui^ular  fibre»,  either  diffuse  or  circumscribed  in  the  form  of  tiunora. 
There  also  exi^t  myomaia  of  the  scrotum. 

'Jlie  digestive  tract  présenta  lormationa  of  the  same  nature,  in  the  shapOl 
of  [Kilypi.     The  latter  myomata,  like  those  of  the  uterus,  are  at  first 
interstitial,  but  after  a  variable  time  they  become  pedunculated,  and 
project  at  one  time  into  the  visceral  cavity,  at  another  time  into  the  peri< 
toneal  cavity. 

The  anatomical  diagnosis  of  these  tumors  is  impossible  without  the  aid 
of  the  microscope.     With  ihi»  instmnu-nt  their  recognition  is  generally 
easy.     In  doubtfid  cnses,  reconnic  should  he  liad  to  dissociation  of  tbo  i

volume  they  iletcrmine  lesions  of  the  neighboring  tissues,  or  offer  obstaclea 
to  the  proper  function  of  important  organs.  Thus  a  niyoma  of  the  uterus, 
may  compress  the  blailder  or  the  rectum,  and  occasion  congestions  aodj 
hemorrhages  of  the  mucous  membrane,  and  other  uecidonts.  The  pcdun-

S  toyed  to-day  by  patholo^sts,  this  word  should  be  exclusively  used  to 
eeii^ate  tumors  constituted  by  nerve  elements. 

Tho  foBcicuIat^rd  neuromata  are  then  simply  tumon  constituted  by

alxnvlaut  iiro-luction  of  fibrous  tissue  between  the  tubes  of  one  or  more 
ne  ne- bund  les,  so  that  the  ncnos  have  aur;mente<l  considerably  in  size 
while  preserving  tlicir  cylindrical  form.  This  afFeclion  is  not  aceornpa- 
nted  by  a  new  fonuation  of  nervous  elements,  and  it  should  tu>t  be  called

firstt  sight  as  a  new  formation  of  tihrous 
tissue.  Valentin  and  l.ehert  have  fonnd 
iu  them  a  Inrjjo  qnantity  of  nerve  lubes 
with  double  eontonr.  In  dissecting  these 
luiuora,  a  bundle  of  nerve  tubes  is  seen  to 
penetrate  »  little  snellins.  Within  the 
latter  the  norw  tube»  intc-rlnee  and  form  ' 
siniitwitir»  and  loops;  it  is  difficult  u>  de- 
termine if  these  tubes  are  oontitmonit  with 
those  of  the  cut  nerve.  The  rery  <lcntie 
fibrouH  ti^tue  uhicli  separate!)  them  makes 
dissociation  and  isolation  of  the  tubes  trou- 
blesome, and  the  winding  course  of  the  lat- 
ter makes  it  difficult  to  follow  them  in  the 
seetioTi  for  «ny  considérable  distance.  Wo 
shall  soon  see.  while  stnilyinj!  the  plieno- 
mena  of  cicatrisation  of  nerves,  that  llie  embryonal  tissue  of  the  cicatrix 
lias  the  tendency  m  produce  nerve  tubes. 

Intitead  of  being  single,  there  may  be  numerous  neuromata  alon^  the 
whole  course  of  a  nerve  ami  it«  divisions,  along  a  plexu,*.  or  along  allj 
the  nerves  of  a  considerable  nart  of  the  body,     'I'umors  of  the  optiu  i 
nerve,  which  have   been  callea  neuromata,  are,  according  to  Virchow, 
mostly  myxomata. 

The  .w'AT^iMiCAL  DiAONOrils  of  ncuToma,  difficult  in  the  amyelinic  ra< 
riety.  is  simple  when  they  possess  double  contoured  fibres. 

In  order  that  a  tunmr  should  merit  the  name  of  neuroma,  it  i«  not  suf>

Di:siiLii-rit)X. — Lymphadenoroata arc  tu- 
mors of  extremely  variable  sise,  from  that 
of  a  millet  seed  up  to  that  of  the  head  of  a 
ficlns.  They  almost  always  have  ill-de- 
fined limit*.  In  the  lymphatic  glands  they 
resemble  a  simple  hy|)crlrophy  of  these 
orgaiii),  hut  when  Hcvenil  adjoining  glands 
arc  involved,  they  are  confounded  in  a  eom-J 
mon  mass.  Tlicy  have  a  decidedly  enceph-l 
aloid  aspect:  they  are  soft,  gray,  with  r 
points  which  correspond  to  dilatations 
vessels  and  ecchymoses  :  tlicy  «omclimc 
present  opaque,  cheesy  portions.  Tliese 
tumors  yield  a  very  abundant  milky  juice, 
exactly  like  that  of  carcinoma. 

This  juice  consists  of  a  fluid  in  which 
flonts  small  round  cells,  having  a  mean  dia>

For  tlicir  recoRoition,  it  is  nrcossary  to  study  thin  sectioiks  which  have 
been  jicncillcd.  'l*lio  reticulated  stroma  which  forms  the  reiil  basis  of 
these  tumors  is  Uien  very  cvidonl,  ftml  is  seen  to  be  tn  conueetion  with

increase  in  the  sise  of  the  follicle.^,  which  nre  compi'ciiscd  and  modified  in 
fonn.  The  connective  tissue  of  llio  medullary  part  seems  to  have  dis- 
ap[fenrcd,  in  onlpr  to  make  room  for  the  hyperirophicd  cortex.  Upon  tlio

The  thymus  gland,  even  at  the  h)^  nhen  it  has  undergone  almost  com* 

Eilete  atrophy,  may  in  leiicoeythiemia  or  adaenia  réassume  iu  orignal 
imn,  and  become  the  seat  of  adenoid  tissue. 

The  spleen  may  suffer  an  attcradon  simitar  to  that  of  the  lymph  glanda. 
The  le«iou  is  in  the  Malpigbian  bodies,  which  corre»|iuud  to  tiie  folli- 
cles of  tlie  lymph  glands. 

'Jlift  liver  preitcnts  many  distinct  alterations.  Tlie  one  which  is  jiecu- 
liar  to  hiueocylhwraia  consist!»  in  a  diltmte  njwplexy  of  white  blood  cor- 
puscles. The  whiti.^h  i.«lands,  which  in  the  liver  have  been  reganled  as 
caused  by  a  hyperplasia  of  the  connective  tiitsue,  result  in  this  cane  from 
an  accumulation  of  white  blood  corpuscles  ;  the  hepatic  capillaries  allow 
the  escape  of  a  larj^e  ciuantity  of  white  corpuscles,  which  spread  them- 
selves belwccn  the  liopatic  cells  in  a  limited  or  ditl'usc  manner.  The 
liver  cells  undergo  fatty  degeneration,  and  may  be  thus  destroyed.  We 
bare,  then,  not  a  formation  of  adenoid  tissue,  but  a  real  ttpoplexy  of  the 
white  corpuscles  of  the  blood.  Besides  these  «mull  products,  there  are 
in  the  liver  (genuine  new  formations  of  reticulated  mletioid  tissue.  I'cr- 
baps  the  extnivasAted  white  corpuscles  above  mentioned  may  bo  the

is  itol  ao,  and  that  there  tlie  origin  of  Mie  lymphadenomata  of  the  liver 
must  be  altribuud  to  a  hyperplasia  of  the  coiniective  tissue.

In  a  second  phase,  some  of  the  embrvonal  cells  put  forth  niimeroua 
prolongations  which  come  in  contuft  wiiii  each  other,  unite,  ami  form  a

IX.— TUMORS  nAVIIfG  THEIR  TYPE  IN  EPITUEtlAt,  TISSUE, 

In  the  skin  wo  hare  a  structure  showing  the  variations  which  the 
epithelial  cells  can  experience  under  varying  physical  conditions.  Wo 
do  not  think  that  the  di«linction  created  by  [lis  between  endothelium 
and  epithelium  can  be  accepted  ah  absolute  ;  iiud  the  opinion  «f  'HiieiXih 
that  all  epithetia  «print;  tn^  «n  epithelium  seems  to  us  contradicted  by 
what  takes  place  in  the  formation  of  the  epithelial  celLi  which  cover 

Sranulalions  and  fislulae.     It  is  very  probable  in  this  ca.se  that  the  epi- 
lelia  aie  derive<l  from  embryonal  tissue. 

The  hiatorv  of  cancroids  demonairates  very  positively  the  formation  of 
epithelial  cells  in  parts  which  are  void  of  tlieni  in  ttie  normal  state;  for 
example,  in  the  medullary  tissue  of  bone,  in  the  lymphatic  glands  and  in 
muscles. 

in  tumoTf,  cpitliclial  tissue  niny  astume  different  characters  which  give

stmilnr  to  tlinl  of  the  »kii),  ia  oKierved;  that  ia  to  s&y,  we  find  first  a 
lajer  of  cylimlrical  cells,  Inyers  of  dentate  cells,  then  flat  comeoTia  cell», 
which  heconiing  dry  form  an  epidermic  globe  at  the  centre  of  the  lohnlo. 
The  mode  nf  forrantion  of  these  cell-nesta  is  th««  easily  undcretood. 

The  lohulea  are  separated  from  one  another  by  a  Htroma,  Benertlly 
oonsiatîng  of  connective  tiasuc,  which  scn'cs  to  sustain  the  urt«ric«,  ca)>il-

Lobulated  pavement  epitheliomiita  )ire«enl  varielio*  according  to  the 
faistoIo;^eal  alterations  of  the  stroma.     The  strum»  may  be  composed  of — 

a.  Kmbryonnl  liwue  with  DumerouM  vessels; 

b.  Mucous  connective  li»»ue  ; 
e.  A<lult  or  fasciculated  connective  tissue  ; 
d.  All  those  varietiea  of  tissae  combined. 

Aliemlionii  in  nutridon  of  (he  cells  of  epithelioma  permit  of  the  recog* 
nition  of  two  varieties  :  rotl"il^  and  corntnu». 

They  are  annlngona  to  what  we  observe  in  the  epidorm,  where  the  cpi- 
ilenuiil  cella,  instead  of  drTin<;,  become  colloid  when  there  is  an  irritation 

of  the  skin.  At  the  commencement  of  the 
alteration  the  ilenUit*.^  cells,  from  an  iii- 
creimcd  nutritive  supply,  show  a  vc«icnlar 
state  of  their  nucleoli.  The  nucleus  itself 
becomes  distended  by  the  transformed  n^^ 
cleolus.  Thia  nnwJihcaiion  is  observed  in 
the  cella  of  lohulated  epithelioma.  Soon 
the  cells  themselves  become  vesicular  and 
tilled  with  colloid  matter  ;  they  may  then 
open  into  each  other  and  forin  iin  areolar 
system,  of  which  the  trahecul»;  arc  formed 
by  flat  ei>idermic  ceils.  These  elenicntury 
lesionx.  which  are  seen  in  ve.iidcs  and  pus- 
tules of  the  skill,  also  sometimes  appear  in 
epithelioma.  In  the  latter,  the  most  com- 
mon modilicationa  consist  in  a  colloid 
drop  which  replaces  the  nucleus,  or  the  colloid  matter  may  be  formed 
around  the  nucleus  in  the  protoplasm  of  the  cell,  and  crowd  the  nucleus 
to  the  periphery.     (Hr.  110.) 

Both  the  colloid  and  corneous  transformation  of  the  cells  of  epitheli- 
oma  may  be  present  in  the  same  tumor,  which  is  rare,  or  one  may  exist 
singly,  when  we  have  colloid  or  corneous  epithelioma. 

liobulated  eplthelt'>mata  arc  subject  to  «/•vnifi'in.  This  idceration  is 
caused  by  disiiite;{ralion  of  the  epithelial  cells,  or  by  gangrene  following 
obliteration  of  the  vessels. 

In  the  first  case,  the  cells  constituting  the  lobules  easily  liecome  de- 
tached from  each  other  by  softening  of  tbeir  cement  substance,  and  fonn 
a  grumous  mas*  which  can  bo  s(|ueezcd  from  the  tumor  by  lateral  pres- 
sure upon  it.  The  proliferation  of  the  connective  tissue  at  tlie  surface 
of  epitiicliom.ita  may  be  intense  enough  to  give  rise  to  granulations.  We 
have  then  a  papillary  surface  covered  with  epithelium,  as  in  the  adjoin- 
ing figure.  (Kig.  HI.)  A  partial  or  a  total  gangrene  of  the  tumor

of  the  skin  and  mucous  membranes,  or  in  neighboring  embrj'oual  tissue 
of  new  formation. 

Rindflcisch  entertains  tlie  opinion  that  the  ne»  epithelial  tinuc  ma; 
also  be  ileTclopcd  bj-  tlie  appsition  and  metamorphosts  of  young  and 
small  coll»  in  the  connective  tissue  at  the  border  of  the  epithelium.  We 
admit  (he  orrcctness  of  this  opinion  in  many  case^,  and  think  tJiat  tbe 
fact  i#  to  be  oxplaineil  by  a  sort  of  iftion  Je  prttMnrt,  or  epithelial 
infection.  We  reco^^nixe  iu  this  an  occurrence  analogous  (o  that  which 
is  seen  in  embrjona!  tissue  when,  irrespective  of  iti4  origin,  it  is  trans- 
formed into  bone  in  die  neighborhood  of  bone,  into  mii«cle  and  nerve 
when  it  is  in  oontinuity  with  those  tissues. 

Lobulated  epithelioma  is  u:jually  developed  by  an  extension  of  tbe 
rclc  mucoeum  at  the  bottom  of  the  inlcrpapillary  projections.  The  epi- 
thelium pcnt'tniteB  the  dorm  by  u  growtli  of  new  celts,  formed  very  prx>b-

tissue.  These  epitlielial  offithoots  bury  tlienij^elves  in  the  derm  while 
presenting  constrictions  from  jioint  to  point  in  such  a  manner  as  to  afford 
a  lobulated  aspect.  Hpillielial  shoota  may  also  often  arise  from  the  lateral 
portions  of  old  pegs.  The  epithelial  massea  may  originate  in  the  hair  fob

more  intci'esting.  In  the  develop- 
ment of  epithelioma  from  tliem,  we 
observe  at  first  an  accumulation  of 
cpitheliam  in  their  interior;  their

They  consist  of  small  pavement  epithelium,  and,  bv  ulterior  modifications

Ukkisition. — 'l\ibulated  epitheliomata  may  be  defined  as  tumors  com-

no  epidermic  evolution,  anastomosing  witli  one  another  and  imbedded  ia 
a  stroma,  which  con^itt»  of  emhryonul.  mucouM,  or  fibrous  tissue. 

The  first  «tage  of  dwelopment  of  lolmlutt'd  cpithelioinau  from  sudori- 
paroiLS  glands  gives  exactly  the  sami;  pictnn'  which  tubulated  epithelio- 
mala  present  iu  their  tilate  of  complet»  development.  Hut  it  should  not 
be  inferred  from  this  that  tubulated  epitliciiomata  are  cancroids  which 
have  conuQcnced  in  the  sweat-glands  and  have  been  arrested  in  the  first 
stage  of  development.  They  may  appear  in  organs  which  have  no  sudo- 
rimrous  glands,  as  in  the  uterus,  even  in  paru;  which  have  no  glands  at 
all.  as  in  the  lymphatic  glands. 

J  Desciiiitiôx. — These  tumors  are  regularly  gphericul.  or  oroid.  f  pon

structure,  pvegments  of  cyliiiders  compcsKd  of  piiveuimtepitheliuin  are 
thus  oht.iined.  These  cylinders  unmeliriies  are  branubed;  tlieir  bodies 
are  regular  and  generally  |iarnllel;  tlieir  extremities  are  limited  by 
irregular  sinuous  edges,  the  result  of  breaking.  The  ceils  wbieb  consti- 
tute them  are  small,  of  equal  siae,  and  limited  not  by  a  sharp,  but  by  a 
dentate  border  in  such  manner  that  with  a  slight  enlargement  and  a  poor 
cbjecuvc,  their  boundaries  cannot  bo  easily  dis  tin  }>ui  shed.  (Fig.  IV-i,

free  nuclei,  and  the  cells  or  perhaps  tbc  fasciculi  of  conneetivv  tissue. 

But  the  various  eleuient«  funiîsbed  by  scraping  are  not  characteristic

coiitViiinded  \tilh  epitlirluid  and  colloid  c  it  re  î  noma. 

They  are  characteriied  by  irregular  or  tubular  cavities  juived  with 
one  or  more  layers  of  cylindrical  cells,  and  separated  by  a  stroma  whidi 
may  be  fibrous,  embryonal,  or  mucous.  Their  cylindrical  cells  arc  similar 
to  those  which  cover  certain  mucous  or  glandular  cavities,  and  are  always 
implanted  perpendicularly  to  the  wall,     (Fi;',  WA.) 

Tb«  aspect  these  tumors  present  to  the  naked  eye  is  variable.  They

They  jiotwcM  on«  or  more  ovoiil  nn-

cylindrical  cclU  are  found  united  at

contAured  free  border,  an  ohject  in 
itself  sufficiently  characteristic  to  jus- 
tify one  in  af5nmn;j;  the  presence  of  a 
cylindrical  enilhetium. 

Tlic  histological  nature  of  the  tit- 
mor  must  be  lcanic<l  by  examination 
of  tbin  flections.  In  the  latter  one

Tiiese  tubes  sih)  npace^,  wiiich  some- 
tiuKS  are  sinuous  and  present  papillie 
at  their  surface, appear  to  have  no  con- 
nection with  the  neij^liboring  inlands. 
The  latter  may,  however,  become  hy- 
iwrtrophicd,  and  form  a  very  distinct 

layer  upon  the  eurfaco  of  the  tumor.  The  celU  are  directJy  planted 
upon  the  struma,  without  the  interposition  of  any  basement  membrane. 
The  free  surface  of  the  tumor  is  often  Uie  seat  of  papillic,  which  are  also 
covered  by  cylindrical  c|)ithc1ium. 

If  the  tumor  lia^  completed  ibs  development,  the  stroma  i«  f;ener.illy 
fibrous.  Hut  it  \*  vClen  embryonal,  and  in  certain  eases  it  is  entiiely 
mucous,  aa  in  myxoma.  The  stroma  ntwnys  carries  vessels,  which  are 
abundant  and,  if  the  stroma  is  vmbryonal,  nnnlovitiiK  to  those  of  sarcoma. 
L'aually  small  in  amount,  the  Mroma  may,  on  the  contrary,  predominate 
and  constitute  the  hulk  of  the  tumor.  The  vessels  may  aometimea  under- 
go dilatations  which  are  fretpient  in  the  mucous  form. 

A  very  important  and  very  common  variety  iscliaractemedbyacoll<Hd

In  the  ovaries  we  haro  seen  non-cystic  tuinors  resembling  carcinoma 
to  the  naked  eye,  which  were  in  reality  epitholiomats  with  cyliodrical 
cclla.

located  iu  the  iut«mal  organs,  ii  is  generally  impossible  to  diflerentiaie 
them,  during  life,  from  the  variotis  forma  of  carcinoma  whose  fatal  pfO' 
grcsB  and  mulignnucy  they,  moraover,  simulate. 

UiMisosis-— Their  anatomical  diagnosis  is  usually  very  easy.  They 
should  be  carefully  tliâcrentiatcd  from  medullary  carcinoma  when  they  arv 
aofV,  nuit  from  colloid  carcinoma  when  they  have  undergone  the  same  dcgeit- 
«rutit>n.  In  lliosi*  secondary  fonnatious  in  the  liver  which  have  rapidly 
progressed,  the  centre  of  the  tumor  is  softened,  the  epitbeliai  cells  are 
dissociated  and  loaded  with  fatty  granules  ;  they  have  lost  their  charac- 
teristic  form,  and  they  entirely  fill  the  alveoli.  The  forceps  breaks  them 
easily,  and  reveals  au  alveolar  stroma  similar  to  that  of  carcinoma.  This 
similarity  is  such  that,  if  one  is  not  guided  hy  the  younger  peripheral 
portions,  it  will  be  impossible  lo  make  a  diagnosis.  In  order  to  dis- 
tinguish n  colloid  epithelioma  with  cylindrical  cell»  from  a  colloid  carci- 
noma, it  is  necessary  to  study  with  the  greatest  care  the  recent  poi-tions 
which  have  not  yet  usisumed  the  colloid  aspect.  \Vc  will  speak  of  the

secondary  hyaline  metainorpho^kig,  which  the  cell  trahecultc  of  a  cancroid 
of  ^le  lymph  vessels  undergo.  According  to  tlic  latter  author,  we  have 
in  all  these  cases  to  deal  with  a  cancor-like  proliferation  of  the  cellB 
in  the  lymphatic  network  of  the  part  afTocled.  The  endolhelia  of  the 
Irmph  vessels  multiply  by  division  and  plu;;  up  these  vesaela.  Uyatiue

vegnels  may  end  in  a  total  ilestmction  of  tbc  endothelial  covering  (the 
peripheral  layers  of  celtrt),  when  a  relatively  large  hyaline  cylinder 
Afwears  imhedded  in  the  connective-tissue  stroma. 

Tlie  eoiidiiion  of  the  bloodvessels  in  the  axes  of  the  hyaline  cylinders

and  should  therefore  be  classed  near  the  cancers.]

IThtie  ttimors  arc  not  coneidered  by  all  pathologists  a»  worthy  of  con- 
ttitntiiig  a  sojiarate  group.  For  ns,  the  definition  of  papilloma  .■ilioidd 
correspond  with  that  of  the  papilliv  themselves.  Tt  is  known  that  the 
papillK  are  constituted  by  connective  ti.isue  serving  as  a  support  to 
vessels  which  terminate  there  in  a  network  of  capillaries  or  in  a  single 
tapillary  loop,  and  that  tiiey  are  paved  by  an  epithelial  covering.  These

I  by  adenoma  and  {Mj^ilUry  cyata. 

Ttiff  papilliD  nrewnt  for  sludr  two  parts — tho  papillary  body  ami  tho 
epithelial  covonng.  The  papillary  body  has  tho  form  of  bnde,  more  or 
less  voluminous,  pviujs;  origin  to  a  j^rcater  or  lessor  number  of  secondary 
and  tertiary  papillie.  Its  variable  form  is  dependent  upon  n  new  fonni- 
I  tion  of  vascular  loops.  It  consists  of  connective  ûsauv  in  «bîch  run  the 
vesselit  which  terminale  in  loops  at  the  extremity  of  (he  pnpilhe.  'I'lio 
([unniity  of  coniMCtive  tissue  is  sometimes  so  sli»lit  that  the  epithelial 
covcriti^  sooms  in  some  eoiie.'*  to  rent  directly  uf>on  the  vesHela.  In 
pa|iilloma(a  of  recent  and  rapid  development,  for  example,  in  certain 
cauliHowcr  fun^^i  of  the  j^enital  organs,  tlie  body  of  the  papillte  is  formed 
of  embryonal  connective  tissue. 

I'be  vessels  of  papilloma  are  arteries.  capiUai'ies.  and  veins,  which 
possess  their  usual  structure.  The  capillaries  are  often  dilated  rv;;u- 
larly  or  into  ampulW,  aii<l  their  ruplure  fionirtiuii-s  give»  place  to  hemor- 
rhages which  escape  outward,  or  rcDMiin  iinprinoncd  in  the  papillary  )iody 
am)  become  transfonncd  itito  pigment.  The  vefl!>eld  of  tb«  pa[>ill)t;  may 
present  bud»  and  undergo  calcareons  degeneration. 

The  villous  pupitliv  are  j;enerally  nimple.  and  ibey  may  attain  a  con. 
Hideriible  length,  eapecially  when  they  are  laterally  compressed  against 
each  oUier. 

The  epithelial  covering  of  the  papillte  is  different  according  as  it  is 
formed  of  pavement  or  cylindrical  celU.  In  the  first  case,  a  great 
number  of  layers  of  cells  undergo  an  evolution  identical  with  tluit  of  the 
Malpighian  layer  of  the  skin  or  of  the  buccal  mueous  tncmbrane.  These 
cells  arc  dovi-tuiled  into  each  other,  and  the  superlicial  lavera  arc  flat- 
tened, l'apillomata  often  possess  a  covering  of  pavement  ccll«,  while 
the  mucous  membrane  wheiMe  they  spring  is  covered  witli  cyliiulricul 
epithelium.  These  pavement  celts  are  frei|ucnlly  ve^cular  and  in  a 
state  of  colloiil  degeneration.  When  the  )mpilla  is  invested  with  cylin- 
drical epithelium,  there  is  only  a  itingle  layer. 

Dkvku'Piik.st. — Mucous  papillomala  generally  spring  from  the  villi 
or  papilla*  of  the  mucous  membrane,  but  they  may  form  where  there  are 
no  papiKie — for  example,  in  the  ventricle»  of  the  laryns.  The  minute 
phenomena  of  Uiese  hypertrophies  and  new  formations  have  not  yet  been 
followed  very  closely,  but  the  analogy  of  their  structure  with  that  of 
inSammatory  granulations  support»  the  suppoùtion  that  their  mode  of 
formation  is  simitar.

For  the  recognition  of  a  papillomit  we  must  find  at  the  base  of  the 
papillie  noitiier  alveoli,  nor  gland  ducts,  nor  tslanda  of  epithelium. 
The  cells  situated  between  the  papillie  must  not  be  taken  for  lobules  of 
cfqthelioma;  this  distinction  is  easy  to  mahe,  for  the  latter  penetrate 
deeply  into  the  dermis  or  submucous  tissue,  whilst  the  most  profound  of 
tht'  intorpapillary  colls  of  papiiloratt  are  upon  the  name  levul  as  in  the

tions. 

PROflsOHts. — Tlie  prognosis,  generally  very  benign,  can  heoome  grave 
only  by  reason  of  the  location  of  the  tumor  in  parts  where  it  may  inter- 
fere with  vital  functions. 

Can  papilloma  become  transformed  into  e])ithelioma ?  We  do  not  con- 
sider it  impossible,  but,  up  to  the  present,  we  know  of  do  oliservatioo 
which  proves  it.

tumors,  under  the  niime»  MdciioiiUpolyiidcnoid.hctt'radenoid  tumore,  etc. 
For  as,  adenomata  arc  tiunors  which  offer  th«  same  structure  as  glands. 

Normal  glands  are  divided  into  racemose  and  tubular.  We  also  have 
two  species  of  adenoma:  Isf.  Aeinout  aiifitonut  ;  2d.  Tubuhir  adenoma,

between  »nch  tumors  and  tlie  normal  parts  ii  that  the  glandti  here  «re 
hypertrophied. 

In  the  i)tA(i.\oi;iâ  of  aotnoiui  adenoma,  they  ahoulil  be  aoparated  from 
all  new  products  which,  by  develo|iinK  in  the  ueishborhood  of  glainla, 
determine  a  proliferation  of  the  epithelium  of  tlieir  acini. 

In  the  tumors  which  wo  have  described  up  to  the  present,  we  bare 
«en  that  every  new  formation  atlecling  the  stroma  of  a  «land  is,  at  a 
certain  moment,  nc-companied  by  a  multiplication  of  the  epithelium  of 
the  culs-de-suc  find  of  the  excretory  ducts,  followed  by  a  dilatation  of 
these  cavities  and  by  various  nltorior  modifications  of  their  contents. 
For  example,  every  cnchoiidroma  of  the  parotid  delemiinc»  H  orolifcr»- ■ 
tion  of  the  glandular  epitlielium,  and  yet  no  one  thinks  of  ranging  tlie^fi^ 
tumors  with  adenoma. 

If  the  elands  hypertrophy  at  the  commencement  and  during  the  period 
of  formation  of  tumors,  they  also  underf;o  varied  modiRcation^,  such  as 
fatty  or  colloid  degeneration  of  the  epithelium,  alteradons  which  end 
sotne^mes  in  cysts  or  in  hypcrtropliy  of  the  acini. 

Moreover, when  »  srowtb  containing  very  many  hypertrophied  ;;Ui)du(ar 
acini,  a  sarcoma  of  the  breast  for  in<stnni.-c,  returns  after  removnl,  tho 
new  tumor  no  loii_i;er  contains  -rlands— an  evident  proof  that  there  has 
been  no  adenoma, and  that  the  hypertrophy  of  thi-  glands  in  the  primary 
tumor  was  accessory.  If  the  pritnury  tumor  bad  been  an  adenoma,  it 
would  have  returned  with  it^  primitive  stnicture. 

It  is  by  a  full  knowledge  of  the  iftructnre  of  other  growths  with  which 
they  may  be  confounded,  and  by  an  attentive  examination  of  each  piece 
that  we  iihsll  succeed  in  recogni/jng  true  adenomata.  The  latter  are  to  be 
diagnosed  by  the  condition  of  the  int^racinott^  ti.4^ue  and  the  tmture  and 
diflpoution  of  the  new  acini  which  arc  entirely  like  those  of  the  aR'ected 
gland.  "We  should  add,  moreover,  that  no  tumor  is  more  rare  titan  this 
species  of  true  adenoma.

protrudes  from  the  anus,  the  investing  cylindrical  cells  become  trans- 
formed into  sqiiamoua  epitbelia,  which  may  oven  becone  corneous  at  the

depressions  are  filled  by  stratified  pavement  cells;  the  interglandular

tn  the  dépressions,  analogous  to  the  crypts  and  folda  of  the  arbor  vine, 
which  these  polyps  sometimes  show. 

Among  nasal  polypi  there  are  those  which  arc  so  like  the  cystic  ade- 
nocna  of  the  uterus,  that  it  is  impossible  to  distin^^msh  diflereiiecs  in 
structure.  Cases  arc  also  occasionally  encountered  in  which  the  glands, 
lined  with  cylindricul  epithelium  and  dilated  intv  cjsM,  estnblUh  A  per- 
fect j>iiiiililude  with  the  ju-evioinly  described  uterine  lumora. 

.\asal  polyjii.  however,  arc  most  commonly  constituted  by  raucous 
tinoue,  when  they  belong  anion^  the  myxomata. 

Diagnosis. — -The  only  tumors  with  which  these  adenomata  with  cylin- 
drical cells  may  be  confounded  are  cylindrical-celled  cpitheliomala.  In 
the  great  majority  of  cases  the  dia<;noBis  is  ven  easy:  the  regularity  of 
the  glands,  their  opening  upon  the  mucous  surface,  the  presence  of  cysts 
regularly  limited,  establish  the  diagnosis  with  certainty.  Rpitholiomata 
with  cylindrical  cell*  never  piVKcnt  small  regular  cysts;  besides,  tliey 
show  uherruliiin»  in  the  form  of  the  tubes  «ml  their  «ells,  which  »ep»rato 
them  from  the  normal  type-  Moreover,  they  invade  the  profound  tissues, 
while  adenomata,  always  superficial,  have  the  tetidoncy  to  a»j>ume  the 
form  of  polypi. 

While  the  nttiii.soi-is  of  epithelioma  with  cylindrical  cells  is  very  grave, 
that  of  adenoma  is  very  benign.  Adenomata  are  never  generalised,  but 
they  return  after  they  have  been  incompletely  removed.  [According  to 
some  authors  adenotuatu  arc  occaeionally  subject  to  metastases.]

caused  by  the  pressure  e.\ertcd  upon 
the  walls  by  the  incessant  accumulation 
of  vlemenis  contained  in  the  cyst.  In  i

and  they  never  present  orifices. 

2d.  tn  a  second  variety,  the  cystic  membrane,  together  with  papill» 
analogous  to  tliose  of  the  derm,  [fos»esses  sebaceous  glands  and  hair  fol- 
licles. Thasc  hair  follicles  give  origin  to  real  liair.  In  the  interior  of

It*!.  The  third  variety  of  dermoid  cyal  of  Lehcrt  is  more  complicated. 
Many  iliflerent  tissues — and  even  organs,  for  example,  lecth — appear  in 
Uw  wall  of  the  cyst,  whose  ontctits  arc  tlic  sami;  aa  in  thp  otht-r  variulies, 
vii.,  Mbum,  etc.  The  teeth  are  found  id  a  dutitul  follicle  surrounded  by 
fibroud  tissue,  or  tliey  are  implanted  upon  bone  of  varied  «trttcture. 
Their  disposition  is  very  im-^Inr;  tlicir  d«velopment,  aconrding  to 
Kohlrausch,  does  not  <liflcr  from  phy«io1a;;ical  growth.  TUc«c  t«elli — 
caninff,  molars,  and  incifors — have  tlic  «haractera  of  the  firMt  nnd  second 
dËtilition.  There  may  tic  one  or  more  teetli  ;  in  certain  ca»ca,  llieir 
(iiimtitir  ia  sucii  tliat  K«il  and  Auleiirieth  once  counted  a»  many  aa  -iOO. 
Thiit  olMen'ation  is  niinous  to  the  hyiioCheAiH  of  mapy  aulliord,  that  one 
of  these  cyat^  indicate»  a  fuitat  incliij>ion  at  this  spot.  For,  if  there  had 
been  a  fwtal  inclusion,  it  is  incoioprelionsiMe  why  the  teeth  vould  be  so 
Dunwrous.  Instead  of  a  bony  plate  aervin;;  as  an  insertion  for  the  teeth, 
aometimes  only  an  osseous  border  rpprcscntin;;  an  alveolus  is  encountered. 

Teetl»  and  osseous  tissue  in  the  form  of  plates  are  the  commonest 
occurrcnoe*  in  Ac  wall  of  these  cysts  ;  but  there  may  be  al*o  long  bones, 
cartilaj>e  trre;^lnrty  disposed,  maascs  of  striated  muscle,  and  even  nio- 
dnllary  ncrvv^.  Wu  have  seen  cysts  of  this  kind  where  this  iRTve  tissue, 
uhuraclvrizi'd  by  sronll  ilQiibh'-coutmm'd  nerves  and  nerve  celts,  was  con- 
tained in  a  fibrous  pouch  adjoining  <)A>it>ou')  portions.  Nothing  is  more 
irregular  than  the  <lijfiO!>itioii  and  relative  t|iiantity  of  these  diverse  tis- 
sues. In  places,  the  wall  of  these  cysts  presents  plaques  which  have  tJie 
same  structure  as  the  skin,  po^tsessing  papiuie.  sebaceoum  and  sudoriparous 
glands,  hair  fotlictes,  and  hair  ;  at  other  points  the  «all  is  thin,  smoodi, 
âbrous — analo^^us  to  that  of  cysts  of  the  first  variety.  The  volume  of 
these  tumors  is  rariable  betnceii  that  of  an  c;y;  and  that  of  an  adult 
heart.  Their  mode  of  dcvelopmait  is  not  understood.  It  is  only  known 
that  they  arc  conf;i'iiitnl.  Tlie  most  freipK"«t  seat  of  dermoid  eysts  is 
tJie  ovary  and  the  testicle,  but  they  may  bo  met  witli  also  in  all  th« 
other  organs. 

2d.  Sbkofs,  ^lucovs,  axd  Colloid  Crarfi.— The  second  group  of 
cyald  is  characteri/.ed  by  their  conteiiLi,  which  are  serous,  mucus,  and 
colloid. 

Tla-y  may  develop:  a,  in  natural  serous  cavities — for  example,  tendinous 
or  periarticular  bursie  :  b,  in  glandular  cavities  ;  o,  they  may  arise  any- 
where. 

a.  Serous  cavities  may  be  considered  as  spaces  in  the  midst  of  the 
connective  tissue  which  surrounds  or;;ans  ;  they  are  lined  witii  eodotlie- 
Hum,  which  may  desquamate,  be  destroyed,  and  reformed  again.  We 
should  not  be  surprised,  therefore,  to  sec  regular  or  Irabeciilated  aoci- 
dental  cavities,  lined  throughout  by  eiidotbeliuni,  develop  at  any  point 
in  loose  connective  tissue.

1'he  GraaHan  /"llickg  of  the  ovarif  are  often  lilied,  even  iti  new-born 
children,  and  before  mcustmution,  by  a  large  (luantiiy  of  fluid  ;  this 
constitutes  hydropsy  of  the  follicles.  It  is  probable  that  a  large  number 
of  ovarian  cysts  nave  such  an  origin  (  b'oerster).

3d.  In  titeovariea.  where  they  are  very  frequent,  these  cysts  constitute 
a  variety  designated  under  tlie  name  of  proliferous  cysts.  It  is  not  cer- 
tain, however,  that  at  tlieir  origin  these  cysts  arise  from  »  Graafian  fol- 
licle. What  has  lead  Koerster  and  some  other  authors  to  consider  tliem 
as  foriDcd  of  many  cyets,  is  thiit  their  wnll  at  a  given  moment  it^Of 
forutiB  now  Dy»t«.  No  ouv  that  we  know  of  has  ever  studird  the  initial 
formation  of  tliCM  cy«t».  It  is  po«t>ilile  that  they  mny  be  dovdoped 
from  the  connective  tisane  of  the  stroma  of  the  ovary,  ju-*l  a«  secondary 
cy«të  BCCTO  to  «rise  from  the  cmmective  ti.t.tiie  of  the  tvalU  of  prttnai'y 
cynt». 

Tbene  proliferous  cysts  are  mnst  frequently  encountered  in  the  ovary, 
but  sotuetimes  also  in  the  great  omentum.  Tliey  are  all  muUUocular  and 
bave  characters  which  dUttnguish  them  from  all  of  the  preceding  varie- 
ties. ITicy  poasess  tliick  walU.  which  are  îndcpenrlçnt  or  common  to 
several  cystic  cavities;  their  inner  membrane  resembles  a  mucous  mem- 
brane and  presents  «t  its  surface  papilla:  or  villoaitics  disposed  in  tufts 
or  budding  masses  ;  finally,  in  the  walls  of  those  cysts  wc  bnd  secondary 
cystt. 

'  The  tissue  which  sepurAtes  and  unites  the  difTen-iit  cyst«  \«  mo»!  frv- 
quentiy  a  young  and  very  vascular  connective  tissue,  entirely  embryonal 
in  0ome  places.  In  some  cues,  we  have  found  nmco\u  tissue  therein. 
The  papillic  or  villi  vegetating  upon  the  inner  surface  of  the  cytU  are 
«mple  or  compound;  tlieir  arrangement  U  often  extremely  complicated, 
their  body  consi^iU  of  embryonal  comieclive  liiuue;  tlieir  vesela  are 
numerous  and  often  dilated  mco  ampuUie,  somsiim^^  they  rupture  and 
give  rise  to  ecchymoses.  The  latter  peculiarity  explains  whv  the  fluid 
contents  of  llic  cysts  are  often  luorc  or  less  colored  by  the  coloring  mat- 
ter of  the  blood  or  even  by  vxtravosau-d  blood  ilaolf.  The  papillie  and 
the  inner  surface  of  cysts  are  cov<-rcd  by  epithelial  cells,  sometimes  small 
and  cubical,   but  most  frequently  cylindrical,   and  the  latter   may  bo

ciliatcl.  In  the  dîHercnt  layers  of  llie  walls  of  the  cvsts,  particoUrl^ , 
in  llie  papillary  layer,  little  cysts  are  often  seen  from  llie  suce  of  &  pin- 
head  up  to  that  of  a  bucl-nut,  exactly  similar  to  the  preceding. 

The  contunls  of  these  cysts  is  a  serous  or  colloid  fiiiid,  wboeo  color  ù 
extronii'ly  variable  ;  somedmos  colorless,  it  is  often  rvi  or  dark  brown, 
It  contains  oAU  regular  or  deformed,  in  a  state  of  colloid  or  fatty  dege 
«ration  :  free  fatty  ;;raiiulea;  sometimes  crystals  of  chotvstcri»,  in  siich 
considerable  tjuuntity  that  they  nay  be  seen  iu  the  Buid  by  the  naked 
eye. 

In  the  colored  fluid  aro  encountered  red  blood  di^ks,  variously  altered, 
granule:*,  and  crystals  of  liwmntoiilin. 

The  iir:vKi.iH'MEXT  of  »ecoi)dary  cyaU  has  been  studied  by  Foerster 
and  WiUon  Kox,  who  have  reached  different  conclusions.  Koersier 
olwerved  in  tlie  wall  of  primary  cysts  islands  of  embryonal  cells,  tiie 
oost  liitcrnnl  of  which  underji^o  colloid  degeneration  and  are  destroyed, 
rwhilo  the  perijiberat  remain  and  constitute  iho  epithelial  covering  of  the 
cystic  cavity.  For  Wilson  Kox,  the  secondary  cysla  always  form  bo- 
tween  the  papilUe,  the  villi  joining  together  by  their  free  extremities 
form  at  their  base  cys^c  cavities  lined  by  the  same  epithelium.  8nch  ia 
tiie  mode  of  development  that  can  hti  eiisily  observed.  We  do  not  wish 
to  deny  the  mode  of  dovelopnicnt  indicated  by  b'<x'r«tcr,  but  wo  Iiairc  not 
been  able  to  follow  it  conipleWly,  We  liave  neen  round  islawls  of  em- 
bryonal ti«^ue  in  the  wall  of  ey*w.  but  we  have  not  l>eeu  able  to  recognix» 
the  tramforniation  of  the^e  i-^lands  into  veritable  cysts. 

Thcae  lumora  are  very  analo;;oua  in  structure  and  nature  to  ademmatai^ 
and  papiUomata.  In  fact,  if  one  examines  a  [;ooil  preparation  of  the  waP' 
of  oueof  tbeseeyats,  not  knowing  when?  it  came  from,  one  could  hesitate 
between  a  proliferous  cyst,  an  adenoma — such  as  those  of  the  cervix 
uteri  or  of  the  nasal  foseic — a  papilloma,  and  even  an  «pilhcUoma  with 
cylindrical  cells.  They  also  pn-sent  j;reat  similarity  in  structure  to  »ar- 
comata  devploped  in  ;;Sand».  But  when  one  examine»  the  whole  tun»or, 
doubt  is  no  lon;;er  posslbli^  ;  it  U  readily  seen  to  be  a  ttimor  de-icriWd  by 
all  authors  under  the  iinmo  of  proliferoai  cyst,  a  tumor  which  may  attain 
each  an  enormous  developmeni  as  to  induce  death,  but  which  is  itérer 
generalized  as  are  aarcomnLi  and  carcinomata.  We  aliaîl  aUo  find  genu- 
ine cysts  in  die  following  group  of  tumors. 


X.— mXED  TUMORS. 


In  the  fœtus  or  at  birth,  sometimes  voluminous  tumora  are  found,  con 
stitutetl  by  an  embryonal  tissue  which  has  undergono  euch  an  evolution 
tliat  nearly  all  the  tissues  find  their  representation. 

We  have  observed  two  tumors  of  tins  kind  located  in  the  peritoneum.

tilage, the  two  covered  respectively  by  a  periosteum  and  a  perichondrium;

of  pavement  epithelium  or  of  cylindrical  ciUated  cells;  ôth.  l^ong  chan<

nelB  fiUed  with  cyliadrical  epithelium  or  with  lobules  of  pavement  epi- 
thelium. These  tumors  could  not  be  regarded  as  fœtal  inclusions,  since 
there  was  no  form  recalling  a  fcetua.  The  name  teratoma,  as  proposed 
by  Virchow,  does  not  appear  to  us  to  suit  them,  for  they  have  no  deter- 
mined form  recalling  &  superadded  being.  They  have,  on  the  contrary, 
the  form  of  an  enormous  embryonal  bud,  which  enjoys  the  property 
possessed  by  embryonal  tissue  of  this  age  of  forming  all  the  organic 
tisHues. 

These  diverse  tissues,  muscular,  bony,  etc.,  present  a  degree  of  devel- 
opment much  less  advanced  than  that  of  the  normal  tissues  of  the  sub- 
ject bearing  the  tumor. 

As  the  new-bom  children  soon  die,  it  is  not  known  what  might  be  the 
niterior  course  of  these  productions.  These  complex  emhryohal  tumors 
might  rigorously  be  considered  as  sarcomata  developed  in  the  embryo  ; 
bat  the  multiplicity  of  the  normal  tissues  which  are  met  with  in  them, 
especially  the  presence  of  epithelial,  cartilaginous,  and  muscular  masses, 
separates  them  from  sarcomata  such  as  we  have  previously  described.

AFFKNDI.X  TO  TUMORS. 

Af^er  tlie  definition  which  wc  have  jiiren  of  tumors,  we  dioald  XKDgfi 
among  tliero  neither  accumulations  of  pigment  under  the  form  of  oirvun»- 
Mribed  masses,  nor  hydatid  cy&ts.  Vie  will  hrietly  describe  them  in  tiiia 
appendix  to  tumors. 

SlUPUK  MeLANIC  Ma!!HKS  CIRCVMSrRIBKD  I»  THE  FORM  OF  TtMOHl!. 

SvxoxvMS. — These  «»a\>\c  melanic  mames  have  been  very  frequently 
eonfounded  with  utelaitotic  sarcoma  and  carcinnina  under  the  name  of 
melanosis  or  melanoma.  We  do  ifot  nie  the  term  ttinijile  melanosis  to 
characterise  thejc  masses,  became  the  radical  of  the  word  does  not  rep- 
resent a  tissue. 

Defi.xitio.n. — The  melanic  masses  vbich  we  here  have  in  view  are 
distinct  from  melanatic  sarcoma  and  carcinoma  in  this  that  the  niclanto 
granules  do  not  aecumulaie  in  the  cells  of  new  formation  as  in  the  latter 
tumors,  but  they  infiltrate  the  prc-oxiating  normal  clement*.  Melanic 
pigment  ;^nules  auoumulutc  in  the  cetla  of  nonual  tlsHUc  and  destroy 
tbcni,  and  if  tlie  ucciunulittion  continues,  the  tissue  itself  is  destroyed 
tnd  replaced  by  a  nodule  or  a  tumor  softened  at  its  centre. 

We  i^ve  the  namp  of  melanic  niiissos  to  those  accumulations  of  pig- 
ment ooourring  at  the  sum«  time  in  great  number  at  different  points  of 
the  organism.  Tliey  are  distiri^uUlied  from  pigmentary  inBUrations  of 
the  skin,  tuci-i  mnUnii,  and  frotu  the  pi^^neiiliitioii  ivhtch  is  sometimes 
met  with  around  vessel.*  in  the  nerve  centres,  hy  the  fact  that  they 
destroy  iJie  ti&iues  and  are  generalized  in  all  the  organs  like  tlie  most 
isalij^ant  tumors. 

Dlslrii'TIu.v. — CoRtrary  to  the  habitually  slow  progress  of  simple 
mcUnosts  so  common  in  the  horse,  productions  of  this  nature  in  man 
become  genertiliEed  with  very  great  rapidity,  and  cause  the  death  of  the 
patient.     The  progress  of  the  malady  is  suoh  that  one  is  often  cmbarras.tcd

organîaiD,  or  if  tlie  nmnerous  masses  wliicti  are  observed  proceed  fh)m 
tlic  influence  of  the  same  general  caune. 

Ttiese  melanic  masâca  bave  variable  dimensions.  Tticj  are  «liarply 
bonlc-red,  and  tlieir  periphery  présenta  no  intermediate  tones  ol  lessening; 
color, 

WIh-ii  tlicy  rcuch  the  the  ofttn  almond  their  consistt'iice  isttsuallj  soft  at 
the  ct-nlru,  whilst  at  the  puriphcrjr  tliev  still  preserve  Uto  firameaM  of  the 
tissue  u'horeiti  tlivj  »ru  ilcvtOopud.  The  lar^^ost  contain  at  their  centre 
a  gnimous  fluid,  in  which  the  microscope  reveals  nothing  tUc  titan 
metntiic  granules.  K»r  the  microscopic  examination  of  tliv  i>eri]>hcral 
parlii  which  are  ^-ct  firm,  sections  mnat  he  made  after  hanlenin^.  We 
Rnd  the  elements  of  the  original  tissue  infiltrated  with  melanic  granules, 
vithout  any  indication  of  a  cellular  new  formation. 

In  the  subciitancAii3  cellular  tissue  the  plasmatic  (connective  tissue) 
cells  are  infiltrated  with  pi^imcnt. 

lu  the  peritoneum  the  melanic  granules  are  deposited  in  the  plasmatic 
corpuscles  exactly  a»  in  the  skin.  In  those  trabccuhe  of  the  ereat 
omentuni  which  contain  no  vessels,  eïnùlar  piginontatioD  of  tlic  ««lis  la 
seen. 

In  the  kidney  the  depont  of  pigment  takei  plaoe  ni>w  in  pntcht-s.a^ain 
in  littl'^  black  granules.  Sections  of  tlita  orj^an  examined  nmler  the 
microscope  show  the  location  of  pi^eni  in  the  cellulo-rnsoular  tis:*uo 
and  in  the  j;lomeruli;  the  epithelium  of  the  tubuli  remains  intact  for  a 
lon)t  time. 

We  have  also  seen  the  mamma  present  patches  visible  to  the  naked 
eye.  The  pisment  was  fonued  not  in  the  connccliro  tissae,  but  in  tlic 
duels  and  i»  the  acini  of  the  gland,  in  the  protoplasm  of  th«  epithelial 
cells  around  the  nucleus. 

'i'liis  ]ngment  has  been  found  deposited  «tod  id  the  muscles  of  the 
heart. 

From  these  fact«  it  is  certain  that  the  formation  of  pî^nnent  takes  place 
at  the  same  time  in  the  cells  uf  the  connective  tissue,  in  the  cell;*  of  tlie 
epithelium,  and  even  in  musctilar  fasciculi,  and  that  the  pigraeni  does 
not  come  directly  from  the  cfiloriii';  matter  of  the  hlood.  It  i»  not  a 
^rople  penetration  of  the  pijfmvut,  but  h  the  reault  of  on  action  of  llie 
cell. 

This  morbid  product  can  only  be  confounded  with  melanotic  sarcoma 
and  carcinoma.  From  the  naked-eye  examination  one  may  sn^jACct  a 
simple  melanosis,  if  wo  do  not  find  between  tlie  black  and  the  healthy 
parti  a  xonc  presenting  tints  of  intermediate  coloration,  t^uch  a  ;p^a- 
tion  of  pigiueutation  is  almost  never  absent  in  melanotic  sarcoma  am) 
carcinoma. 

Hut,  to  arrive  at  a  precise  lii^tological  dia;piosis,  it  does  not  suffice  to 
Mvrapo  thv  tumor  or  to  examine  the  elements  obtained  by  dissociation;  as 
we  have  already  said,  it  is  necessary  to  make  thin  sections. 

Oencralination  of  the  melanic  masses  is  very  rapid,  and  death  follows 
in  a  few  montiis.

of  tlie  v&rious  liidUfls  of  tlio  orga»i»iii. 

A  etadjr  of  the  development  of  oascoua  tjsauo  is  necessary  for  the 
uti'lc  rata  Doling  of  most  of  the  pathological  c)ian;^oâ  which  occur  in  bone.

the  embryonic  marrow  of  bone  ;  some  of  tlie  embryonic  cells  thus  formed 
8ub»e>iueutly  hwome  bone  eclls. 

AoMDg  the  embryonic  cells  of  the  medttllnry  suhttauoo  of  bone,  those 
which  »re  iioi  converted  into  bone  cell»  undergo  changes  which  :(e]mrat« 
them  from  iheir  primitive  type.  Some  apjiear  to  have  a  limiting  mem- 
brane developed  around  them,  other»  become  adipose  celU,  a  number

rounding teasels  of  considerable  calibre  and  between  the  adi[H»e  cells  of 
the  mcdulUrT  spaces  or  canala  of  the  long;  hones  ;  finally,  some  of  the»e 
cells  do  not  divide,  while  their  nuclei  multiply,  thus  forming  the  so-oailed 
giant  colls  (myéloplaxcs). 

Almost  til  of  the  pathological  changes  which  take  place  in  bones  have 
tbetr  starting-point  from  the  celU  of  tliu  embryonic  marrow,  or  from  the 
eelb  which  have  undergone  the  raoilifiuutions  above  mentioned.  The

LESIONS   OF   BO^-ES. 


Sect.  I.^Congestioa  and  Hemorrhage  of  Boae. 

Congestion  of  hone  h  inauifeitt^'il  to  the  naked  eye  hy  a  red  coloration 
of  the  innrrow.  In  order  to  diatinguiâU  it,  it  i»  necessary  to  know  tlie 
normal  col<ir  of  ttie  marrow  in  different  bones  and  at  different  periodu  of 
life.  In  the  oteniiiin  and  bodies  of  the  spinal  vertebrw.  the  marrow  is 
rod:  where  we  have  bone  in  process  of  formation.»  similar  color  is  seen. 
In  young  persons  the  oniphysia  in  the  proximity  of  the  ossifyinîî  carlitage 
presents  a  tnie  phy8iolo;j;ical  conf^-stion,  while  in  the  older  portions  of 
the  bone  the  marrow  is  fatty  and  resembles,  in  color,  and  transhicency, 
adipose  tissue.  As  age  ailvance«,  tho  marrow  in  the  bodies  of  tl)o  spinal 
vertebra;  atuI  in  the  sternum  loses  its  red  eolor  ami  becomes  lî^ht«r.  The 
rod  coloroftlic  marrow  i»  not  always  due  to  a  congestion,  and  to  <Ii'tcnuine 
the  cause  a  liint^dagical  examination  \a  nccC'txiLry.  It  is  wecit  that  the 
bone  containing  fre*h  red  marrow  shows  not  only  the  capillaries  dilated 
by  th<^  ncoumulation  of  red  ooq>nscle3,  but  more  frei^iiently  the  conges- 
tion in  accompanied  with  an  abundant  increase  of  the  medullary  cells, 
and  a  variable  absorption  of  the  fat;  there  is  even  at  times  ditfuse 
hemorrhage,  when  the  red  eoqtuscles  are  found  mingled  with  the  medul- 
lary cells.  The  red  corpuscles  which  have  escaped  from  the  vessels 
slowly  iindor;{o  changes,  which  cause  them  to  have  their  coloring  matter 
set  free,  and  tu  iuiîltrate  the  non-culorcd  clcmenls.  It  is  in  tlieso  cases 
that  the  young  cells  of  the  marrow  contun  granules  of  luemaloidin. 

The  red  color  of  the  marrow  in  bone  may  bo  due  to  congvstîont  to 
hemorrhage,  and  to  the  alaliiiii;;  of  the  medullary  elements  by  the  color- 
ing material  of  the  blood.  I'lie  red  color  of  the  marrow  may  be  due  to 
a  new  formation  of  veiiseU,  hut  in  this  case  it  is  not  a  «irajtle  congestion. 
Simple  or  complicated  congestion  of  the  medullary  substance  is  met  with 
under  numerous  conditions — osteitis,  caries,  various  tumors,  rachitic, 
ostco-malacia,  etc.  It  occurs  with  great  readiness,  owing  to  the  vessels 
of  the  marrow  not  being  supported  by  a  resisting  tissue.  It  is  seen 
even  in  simple  physiological  changes,  as  above  stown;  it  ia  present 
during  ossification,  and  it  acconipunles  the  formation  of  new  vessels 
which  oflcn  permit  tbo  red  corpuscles  to  cscajtc  into  the  medullary  parcn- 
chvma. 

Ilemorrhage»  are  froi|uent  in  the  p|iongy  tissue  of  bone  and  under  the 
pcriost^'um,  on  account  of  the  vessels  in  those  hicalities  not  being  well 
supported.  With  traumatic  injuries,  such  as  contusions,  wounds,  aii<l  frac- 
tures, should  he  placed  those  lesions  «here  there  is  a  charigi.>  in  the  walls 
of  the  capillaries,  as  tieen  in  inflammations,  and  in  other  active  new  for- 
mations. The  wall  of  the  capillaries,  formed  at  this  lime  of  embryonic 
cells,  baa  become  so  soft  that  the  red  corpuscles  easily  escape  and  are 
found  in  the  medullary  parenchyma.  In  a  third  category  of  cases,  osseoua 
apoplexy  is  connected  with  one  of  those  general  diseases  in  which  hemor- 
rtiagea  are  easily  occasioned:  cachexia,  purpura,  Icucocythiemia,  etc. 
Almost  always,  when  hemorrhagic  foci  have  been  foand  In  the  different 
viscera,  there  arc  similar  foci  to  be  seen  in  the  epiphyses  and  under  tho 
periosteum.

If  a  hone  of  ai)  animal  i.i  ileim<loil  ami  the  wound  kept  open,  in  a  fev 
days  there  is  seen  upon  the  deniidod  surface  an  ciilar^emcnl  of  the 
Ilavoraian  canals  through  ahsorplion  of  the  osseous  subatancc,  while  at  the 
periphery  of  the  denuded  portion,  beneath  the  perioateum.  ihorc  is  found 
a  layer  of  nowly-rormcd  bone,  a  démonstration  that  an  irritation  causes 
ftt  tm  same  time  both  absorption  and  };ro«'th  of  osaeoos  tissue.  In  order  to 
aiwlentand  why  tiie  ^Jitne  cause  produces  simultaneously  a  diflcrcnt  effect, 
it  beooDMs  necessary  to  study  the  histolo^cal  phenomena  of  oHtcilis. 

The  Gnt  cbftn{;e  ohtMin-cd  in  a  bone  upon  which  artificial  irritation  has 
been  employed,  is  the  formation  of  embryonic  c«lls  in  tlie  medullary 
npaoM,  in  tlie  llavcntiAU  canal»,  and  under  the  perioateum.  The»  cells 
rasemble  tlioso  which  fill  tho  primary  medullary  apac&s  during  the  devid- 
opinent  of  bone  from  cartilage,  or  those  which  are  found  under  the  peri- 
osteum widle  the  bone  incrcasea  in  thickness.  Irritation  of  a  bone  re«iilia, 
tlicn,in  ita  return  to  an  cmbrj-onal  condition,  and  herein  we  find  an  appli- 
Oktion  of  the  general  law  which  governs  irritation  of  any  tissue. 

There  are  two  changes  which  follow  the  formation  of  embryonic  tissue 
in  the  medullary  spaces  and  under  the  periosteum:  A.  Tlie  rnlarije- 
mrnt  of  t/tf  raiuiU  or  medullary  splices  hy  absorption  of  the  osseous  tissue 
wbicb  limits  them }  B.  TUt  j'ormatitn  a/  new  ^rn^mt  Cra/teeul<f. 


A. — The  enlargement  of  the  Haversian  canals  may  be  easily  seen. 
Tlie  osseous  lami-dtte  nre  found  eroded  in  such  a  manner  as  to  form  notches 
{ llowship's  lacunar)  filled  with  embryonic  cells.  (Fl^.  124.)  The  bone

cells  to  escape  and  join  the  cells  already  oceupying  the  medullary  «paces. 
Gradually  the  osseous  lamella;  disappear,  and  adjoining  Haversian  canals 
unite  to  form  irresw''»''  spaces  in  which  the  eiid.ryoiiic  marrow  proliferates. 
Several  Iiypothe*c»  have  been  adv«nc«;d  to  explain  the  cause  of  the  ab- 
Mtrption  of  0«s4roiM  ti.sAue,  but  as  yet  it  remains  in  great  obscurity. 

Killrutli  havin<;  noticed  that  the  -terons  pus  coming  from  an  oaseous 
abitceits  eoolained  lactic  and  phosphoric  acid,  was  led  to  think  that  th« 
solution  of  bone  was  effected  by  these  agents.  The  fact,  however,  that 
the  «ction  of  pus  upon  fragmenta  of  dead  bone  which  form  seiiuestnc  in 
cades  of  necrosis,  is  very  slight,  Is  sufficient  to  overthrow  this  conjecture.

know  that  boue  corpuscles  do  not  proceed  direct);  from  cftrlilaginous 
capsules. 

().  ^Veher  and  Volkmann  consider  the  abgorpdon  of  osseous  tissue  to 
depend  upon  a  fatty  defeneration  of  the  bone  corpnacles.  Tliej  have 
confounded  caricB  with  rarefying  oatcitis.  Later  it  will  be  shown,  that 
true  caries  is  the  only  disease  in  which  there  i»  a  fatt^'  degeneration  of 
ibe  bone  corpuscles,  and  in  which  the  diseased  part  dies  without  being 
again  absorbed. 

The  bone  corpuscles  which  nrc  fnmid  at  the  boundary  of  the  inflamed 
part,  are  frctjuenlly  observed  unbrokcTi  ;  ttie  cell  within  beinj;  slightly 
increased  in  «ikc.  Itnrely  do  we  observe  any  signs  of  proliferation; 
never  in  these  cases  <lo  tiie  corpuscles  contain  granular  fat.  From  these 
stntenietila  it  is  very  dithcult  to  understand  exactly  in  what  manner 
«1)isorption  of  bone  takes  place  during  osteitis.  It  is.  however,  prol^ble 
that,  in  accordance  with  the  opinion  of  Virchow,  the  bone  cells  play  an 
important  roll  in  the  process,  since  in  those  conditions  where  this  cell  has 
lost  its  active  vitality  (caries  and  necrosis),  Uic  solution  of  bone  does  not 
occur,  notwithstanding  the  bone  may  be  in  contact  wiih  elements  similar 
to  those  which,  in  ordinary  osteitis,  fill  the  enlarged  medullary  spac«a.

we  have  a  new  formation  of  osseous  tissue  during  inflammnlion.  When 
tJia  inflammation  has  been  alleviated,  the  atifractuouA  cavities  which  have 
been  exoavated  in  the  Imtir  are  very  won  filled  bj  layers  of  new  oiweoua

face  of  the  bone.  Kven  the  metlullary  canal,  if  the  irritation  attaclcs  the 
central  medulla,  may  also  become  the  seat  of  new  osseous  formations. 

The  relation  between  rarefaction  of  osseoiu  tissue  and  its  formation, 
or  between  rarefvinj*  osteitis  and  formative  osteitis  has  been  clearly  iiidi. 
cated  by  the  foregoinjj.  In  infiammatory  rarefuclion  of  bone,  the  male- 
rials  for  rebuilding  are  already  prepared,  and  tJiey  arc  employed  by  the 
organism  at  the  moment  the  irritation  lower»  itt  intciwity.  Wbilir,  on  the 
contrary,  if  Uie  intensity  of  the  irritation  continues,  the  surface  of  the 
bone  ie  covered  with  f;ranulation  tissue  and  pus. 

These  granulntiims  are  formed  directly  from  the  marrow  contained  in 
the  enlarged  mcilutlary  canals,  and  (hey  ^hnw,  aa  has  been  ol)«erve<I  hj

the  deniidett  surface  is  covered  by  a  granular  and  very  vascular  sofi  layer. 

A  general  description  of  osteitis  having  been  given,  we  may  proceed  to

X.  FoHMATiVK  OsTKiTiM. — E^ry  oslei^s  vhioh  terminates  in  recovery 
deterininea  a  new  formation  of  oa^eoua  tissue.  This  nev  formation  la 
Bomotimea  effected  before  the  cessation  of  tlie  osteitis.  In  a  number  of 
cases  the  ossification  ends  before  exceeding  the  limits  of  the  old  bone; 
Yf  hiMt  it  should  not  be  considered  a  formative  Oîtcitis.  In  other  case»,  tb*  ■ 
new  formation  is  oxuberani,  eiceeda  tlio  limits  of  the  old  bone  or  causes  I 
it  to  become  more  dense;  the  disease  is  now  designated  as  hypenMto«is, 
exostosis,  enostosis,  and  condensing  osteitis,  all  being  includi.il  in  formik- 
tive  osteitis.  Every  osseous  formation  mu«t  not  be  coniiidered  ft.t  tlto 
result  of  an  osteitis  <,see  Oslvoma,  p.  18'.i).  The  Ion;; duration  and  slijçht 
intensity  of  tlie  inflammation  of  the  born-  are  the  usual  caiisea  of  fonua* 
tive  osteitis.  Therefore,  it  occurs  especially  in  deep  and  chronic  abscesses 
of  bone,  in  necrosis,  in  syphilitic  osteitis,  etc.,  these  diseases,  as  wo  know, 
being  characterised  by  their  alowneas. 

Now  osseous  formations  may  be  developed  upon  the  surface  of  the 
bone  under  tlie  periotteum,  in  the  bodif  «f  the  bone,  or  in  tlic  vK^nHnry 
Cficify. 

It.  Upon  the  surface  of  the  hone  we  meet  with  that  variety  of  fonna- 
tive  oMeilis,  in  which  the  inflammation  has  been  of  long  duration  and  of 
slight  intensity.     The  irregular  osseous  majtses  are  named  uMr^fliytr». 
The  trHbccuIiK  and  veeseUof  these  Kujicradded  parts  always  have  a  direc- 
tion different  from  those  of  the  old  bone,  so  that  they  are  readily  distin. 
guished  one  from  the  other.     In  making  a  transverse  section  of  a  long 
bone  covered  with  osteophytes,  the  Haversian  'canals  in  the  old  portion» , 
of  the  bone  are  cut  transversely,  while  those  in  the  new  arc  mostly  cut  ' 
longitudinally.     The  direction  of  the  Haversian  cauais  follows  that  of 
the  vessels  ;  for  the  oateo- peri  osteal  or  granulation  vessels  coniv  from 
the  Ilnvrrsiun  canals  at  the  surface  of  the  bone,  and  it  is  around  thescj 
vessels  that  the  new  osseous  lamella:  are  formed,  as  in  tJie  physiological 
08.*ilicution  from  elements  of  the  embryonal  tissue.     The  new  bone  with 
its  Hnvorsiiin  canals  thus  formeil  is  ingrafted  with  it«  vesseU  perpen- 
dicular to  the  BurtWo  of  the  old  bone. 

In  the  formation  of  oateophytea  which  are  occasioned  by  inflammation, 
cartilage  is  never  found. 

b.  Formative  osteitis  occurring  in  the  body  of  bone  causes  it  to  become 
dense  (condensing  osteitis,  sclerosis  of  bone,  ebuniation).  This  change 
Ï8  habitually  [ireceded  by  an  infiammatory  rarefaction,  traces  of  which 
«re  readily  found  with  the  microacofie. 

If  the  embryonal  elements  contained  in  the  cavities  enlarged  by  the 
iiiRamination  do  not  undergo  extreme  irritation,  they  assist  in  the  fona».'l 
tion  of  new  osseous  layers,  which  cover  the  old  eroded  trabcculic  ;  w

essentially  in  a  «iffusea  suppurative  inHammation,  which  may  be  located 
in  any  part  of  the  bone,  under  the  périoste  uni.  in  the  stiperficial  layer»,

LBSI058   OF   BONES. 


The  primary  and  ]>rc(loniin.iut  symptom  of  the  disease  eonsists  in  the 
ra{ii<l  fonnatioii  of  [iui>.     If  an  incision  i^  nimle  under  tfae  iMriosteutn, 
about  twenty-four  or  forty-ei^lit  houra  after  tbe  beginning  of  tbe  malaily,  • 
a  punilcnt  centre  is  usually  opened  (Louvel).     It  is  in  thetie  casee  of 
rapiil  and  cxtcn^ve  auppuraiion  that  we  find  tliobone  necrosed  in  itawhol» 
extent,  detached  from  its  epipliyaoa  and  perioateuin,  and  floating  in  a  vastj 
abscosH.  A  purulent  inliUration  of  the  spongj'  tissue  of  the  extreiultieB  B»i* 
of  the  medullary  tUsue  is  uow  found;  from  such  n  (juantity  of  pus  accuumlat- 
in^  between  the  (mwous  walls  of  the  llnvoreian  cnnals  and  the  vvihmiIs,  tho

etaiiee  it  never  obi^cncd  iu  lh«sc  ciuies.  The  uveromtd  h»nc  has  the  appear- j 
niic«  a«  if  it  had  hovn  macerated  in  witu-r.    S>  intense  or  ext«nsive  a  sup-  ' 
jmrativc  inflammation  of  heme  seldom  occurs.     It  may  be  limited  to  the 
neighborhood  of  an  epiphysis;  an  abscess  forms  ti])0n  tlie  surface  of  tlte 
bono,  which,  when  o|ieno<l,  ooca;Mon3  a  series  of  anatomical  changes  in 
the  diseased  hone,  varying  according  to  the  case.     In  the  less  seiionai 
the  inSammation  being  superficial  is  followed  by  the  same  lesiona  which  ' 
occur  in  simple  denudation  of  the  l)one,uamely,  rarefaction  of  the  osseous 
tissue  succeeded  by  formative  osteitis. 

In  another  class  of  cases,  Uic  suppurative  inHammation  having  invaded 
tlie  medullary  canal,  openings  by  wliich  the  deep  abscess  empties  itself  ' 
arc  produced  very  slowly  and  by  a  process  yet  unknown,  openings  eitlior 
ill  the  middle  of  the  diaphysta,  or  in  the  proximity  of  the  epipliy^ii^.     In 
the^e  cases  the  irritation  is  intense  at  the  centre  of  the  bone,  widle  at  the 
[icriphory  it  is  very  slight,  but  it  continues  upon  the  surface  as  long  as  ; 
the   inflammatory  action  at  the  centre  lasts.     As  a  consequence,  tbera 
are  formed  under  tine  periosteum  new  osseous  layers,  vhich,  being  placed 
one  over  the  other,  cause  a  considerable  increase  in  the  diameter  of  lbs 
bono.     This  peripheral  formative  osteitis  is  produced  according  to  tbs  ' 
process  preriously  describod.    A  partial  necrosis  is  a  very  frecjuent  result 
of  suppurative  osteitis,  when  the  latter  is  limited.

enlarged  hy  the  prolifération  of  the  marrow  and  the  absorption  of  Ui«

uliv  and  aW  those  in  wliich  the  vessels  arc  obliterated,  until  the  canala 
communicate  one  with  the  other.  The  disappearance  of  the  tmlwculw 
entirely  isolates  the  seipicstnim  in  the  midst  of  a  ^ntnulatin^;  marrow. 
The  re-iult  of  chU  process  is  tliat  the  !ii><|uestruni  is  bounded  by  a  tiinuous 
surface,  the  prominencea  of  which  corre^jiond  to  tlic  vascular  distribution 
where  the  circulation  has  coaw'i. 

The  procesa  of  elimination  diRcrs  acconling  to  the  situation  of  the 
Bequostmm.  If  at  the  periphery  of  the  bone  under  tlie  pcrioateum  or  at 
the  end  of  a  cut  bone,  it  is  very  soon  aepantted  and  surrounded  by 
pus  ;  upon  the  surface  of  a  large  wound,  as  an  amputation  or  denudation 
of  the  bone,  the  mortified  part  is  eliminated  ivithout  difficulty.  If  there 
is  no  wound  comniunicatiug  cxt«mally,  s  deep  abscess  is  formed,  which, 
when  ojiened,  cither  spontaneously  or  with  the  knife,  the  se(|t)eslnim 
ciami>lelely  detached,  i»  dlscharj^d  with  the  pus.  But,  when  th<t  entire 
bone  or  tJie  diaphysis  is  tmisformvd  into  a  se<(uestruni,  the  subperiosteal 
marrow  proliferates,  becomes  embryonic,  nurl  occasions  the  formation  of 
new  osseous  tistiue  under  the  periosteum.  The  new  osseous  layers  {çradu- 
ally  grow  thicker  until  the  old  necri>*ed  bone  is  inclosed  in  a  new  bone, 
from  which  it  is  separated  by  a  layer  of  granulations,  llie  sefjuestrum 
is  now  said  to  bo  invaginated. 

The  invaginate-l  sequestrum  is  never  in  contact  with  the  «nvelofMng 
bone.  The  latter  is  covered  with  a  layer  of  granulations  which  con- 
stantly forms  pus.  AVhen  the  pus  is  not  readily  discharged  by  fistular 
openings,  it  accumulates,  desiccates,  and  undergoes  caseous  trunsfonna-

auiemio  (atonic,  torpid,  and  caeoouâ  caries),  also  a  necrotic  cnriM.

gentrnti-m  of  th<  reUi  CHtmnfd  in  the  hmc  furpuii'-lr». 

Personal  investigations  haw  led  us  to  recognise  two  distinct  stages  io 
caries:— 

In  the  first,  tkt  hone  nlU  undcrgo  fatti/  Jegmeratvm  «ith<mt  any 
prfrimit  injtammatori/  aet!'>n. 

In  the  second,  the  cellular  elements  of  the  osseous  trabcculm  haring 
died,  tliey  constitute  so  many  hhoÎI  foreign  hodiea,  whifh  niri-man 
arountl  them  a  mppuratht  innammatmn. 

Thiii  xeoond  stage — in  which  the  osteitis  présenta  special  charactenii  in 
conaci[uenc«  of  the  cause  which  has  produced  it — i»  the  only  one  which 
has  been  described  by  vrriter». 

Cariefl  generally  occurs  in  the  proximity  of  the  articulations  ;  it  is 
alirays  aocompanied  or  preceded  by  a  chronic  affection  of  the  joint — 
iphitf  neeftinff.  The  epiphyses  of  an  artlculutloii  altjteki^d  with  a  recent 
white  swelling  are  formed  of  very  thin  trulwciilio  surrounded  by  an  adi- 
pose marrow.  By  a  stream  of  water  wv  are  nlile  to  wasli  away  the  fat 
tissue  sn<l  isolate  the  delicate  osseou.t  relicuUim,  which,  by  microscopical 
examination,  is  »e<^n  not  to  liave  undergone  any  lo-Htt  of  aub^tanco,  sucb 
as  the  eroding  or  notching  occurring;  in  osteitis.  Their  tliiuncsa  at  this 
time  can  only  be  explained  by  a  regular  absoqxion  of  their  surface,  or 
hy  an  arrest  of  development — a  satisfactory  hypothesis,  if  it  occurs  in  a 
subject  whose  bones  are  growing.  It  is  in  these  trabecnlw  that  arc 
found  the  bone  corpuscles  metamorphosed  into  granular  fat  with  atrophy 
of  their  nuclei.  This  fatty  degeneration  of  bone  cells  is  found  only  in 
caries. 

The  characteristic  alteration  of  the  first  stage  is  continued  into  the 
second.  New  lesions  now  occur,  which  are  appréciable  to  the  naked 
eye,  and  correspond  to  th«  aiuitumiciil  description  of  curie*  a.*  given  by

A. — Frarttir^»  mnipliMtfâ  tvith  wcunil»  (compoun<l  fractures)  are  the 
noHt  simple  in  a  liistolu<;icHl  jioiiil  of  view,  those  in  which  bone  is  most 
rapidly  producod.  Tliu  chaii^us  occnrrîii;^  are  idcniionlljr  thv  same  aa 
in  osteitis;  at  all  the  irritAt«d  points  of  the  i^urfaoo  of  tlic  solution  of  con- 
tinnity,  the  marrow  becomes  embryonic  and  undergoes  changes  «imitar 
to  tliose  of  «  simple  osteiti».  Under  the  peristeum  the  new  embryonic 
marrow  tioon  forma  os^eoiui  tralicoiilic;  five  or  nix  days  after  the  accident 
tfiey  mav  be  found.  The  llavemian  canals  opened  hy  the  fniclure  are 
enlarged  through  the  absor|>ltDn  of  tlie  oaseous  substance  limiting  tlien  ; 
the  ve^els  and  marrow  which  they  contain  contribute  to  the  formation  of 
the  j^ranulativc  tisane.  The  marrow  in  tlio  central  modulUry  cavity 
undergoes  the  same  mod  ï  fient  ions,  a  1th  on;;!)  more  slowly.  Thus,  over  the 
whole  surface  of  solution  of  continuity  there  are  formed  ;;ranulalion3 
which  enlarge  and  hy  uniting  together  constitute  an  embryonic  or  inflam< 
matory  tissue,  in  the  midst  of  which  osseous  trahcculsc  are  developed, 
as  in  the  physiological  method  of  ossification.  The  neodle-likc  pointjt  of 
the  old  hone  seem  always  to  net  a*  a  biife  for  the  now  owteous  formation, 
(irowingin  every  direction,  nniting  one  wiili  the  other  and  with  the  opfioMte 
fragmente,  liicy  limit  the  spaces  filled  with  the  embryonic  m&rrow.  These 
spaces  are  gradually  narrowed  by  the  addition  of  new  osseons  layers, 
and  consolidation  ia  brought  about  by  a  6rm  adhesion  between  the  two 
fragmenta  of  hone. 

In  cxperimcDtx  made  upon  small  mammifcra;.  tt  frecinentlT  occurs 
that  the  suppurative  indanunation  is  limited  to  the  part  which  is  in  con- 
nection with  the  external  wound,  while  the  deeper  part  of  the  fracture, 
not  in  contact  with  the  itir,  Mimrtime?  presents  cartilaginous  masses.  It 
will  be  seen  that  this  formation  of  cartilage  occurs  in  fntctures  not  oom- 
plicatiîdhy  wounds.  Suppuration  nvt  confined  to  the  surface  of  the  ossi- 
fying parts,  is  similar  to  that  which  is  seen  in  suppuration  caused  by  a 
sei)ucstrum.  Tlie  formation  of  callus  in  this  case  does  not  essentially 
ditfer  from  the  formation  of  bone  aa  observed  in  uecroMs. 

S. — Frai'turft  not  nmpUrated  trilh  wintntla  (simple  fractures),  both  in 
man  and  animals,  give  n»e  to  a  cartilaginous  callus,  which  later  be- 
comes ossified.  Until  the  time  of  tho  excellent  work  by  Cruveilhîer,  the 
formation  of  callus  was  interpreted  dificrcntty  hy  different  writera. 
Their  theories  may  he  classified  into  three  groups  :  1st,  that  of  Duhantel, 
who  derived  the  callus  fi-om  the  penosteum  ;  2(1,  that  of  Ucllor,  in  which 
an  osseous  fluid  was  exuded  lietweon  the  fragments;  3d,  that  of  Troja, 
according  to  whom  the  ends  oF  the  fractured  bone  put  forth  granulation 
tissue,  which  is  afterwards  ossified.  According  to  the  last  theory,  cica- 
trization of  the  bone  is  eR'ected  through  the  graimlation  tissue.

of  tl»e  cnlIiiH,  whether  it  be  îti  the  mtisclo  or  periosteum. 

The  only  objection  to  this  doctrine  is  that  it  is  not  general  enough,  for 
the  marrow  contained  in  the  medullary  cavity  and  in  the  Haversian 
canals  may  furnish  the  éléments  of  couaoHdatton.

Soon  cUHnj^eidw  to  irritjition  are  [iro'lHced  in  the  ^uhpcriosteal  marrow 
and  in  that  coniained  in  the  llavemnn  canals.  This  irritation  reaching 
the  perioileum  ami  neij^hboring  connective  tiitaue,  occasions  the  forma- 
lion  uf  numerous  cellular  elements,  ho  that  in  live  or  six  days  after  the 
fracture  all  these  tissues,  snolh^n  and  rich  in  cells,  assist  in  the  formation 
of  a  peculiar  mass,  of  firm  consistence,  hut  not  yet  cart i la gi nous.  Under 
the  periosteum  and  between  the  two  fragments,  ap])c!ir»  a  thin  pulpy 
layer  which,  when  examined  with  the  microscope,  is  found  to  consist  of 
cells,  varying  in  shape,  like  ttioso  of  the  embryonic  marrow  ;  in  the  midst 
of  lliCM' cells  red  blood  corpuscles  and  blood  pigment  are  seen.  The  mass 
of  peripheral  embryonic  callus  is  entirely  sepnrnicl  from  tlic  hone  by 
thi*  l»ulpy  layer.  The  peripheral  mas*  is  bounded  intemnlly  by  llie 
smooth  pcxrly  aurfftco  of  the  p<>rio)tt«um.  Whon  the  eurt'sco  of  the 
bone  b  completely  stripped  of  tlie  preceding  pulpy  layer,  tlie  Ilaveràian 
canals  appear  in  the  form  of  red  jraints  or  lines,  like  those  seen  io  the 
beginning  of  osteitis. 

At  a  later  period,  about  the  eighth  day,  the  cellular  elements  of  the

that  occurring  in  the  physiological  ossification  of  a  short  bone.  There

Sect.  TI.— Tumors  of  the  Bonet. 

All  the  varieties  of  tumors  previously  described  are  met  with  in  the 
bones  ;  but  tho.'*e  occurring  most  freijuently  are  the  sarcomata.  In  study- 
ing the  seat  of  tumors  of  the  bones,  an  important  distinction  should  be 
made  according  to  whether  the  tumor  is  primary  or  secondary.  In  the 
first  case,  it  is  gi^neraily  the  hones  exposed  to  external  injuries  which 
are  most  frequently  affected,  as  the  tibia,  frontal,  maxillary  ;  while  the 
bones  most  frequently  att.'kcked  by  secondary  formations  are  tlie  Sjiinal 
vcrtebne.  sternum,  and  riha.  that  ia,  tho.*e  in  which  red  marrow  iini

in  a  booe,  invade  it  gradually  by  <lcalroying   tlie  osaeous  tissues  as

Fatf-icular  or  »pindle—^lkd  iaftmata  of  the  bones  arc  more  com- 
mon than  the  preceding  variety.  The  fascicular  character  of  the  tumor 
is  more  or  le**  complete,  and  gives  them  u  variable  consistence.  It  is. 
at  times  difficult  to  disiinguip^h  between  encepluiloid  sarcoma  and  fasci- 
cular can'Oina,  esin'oijilly  in  cascs,  not  uncommon,  wherti  both  varieties 
of  tissue  are  found  in  the  same  tumor.  The  soft  fascicular  sarcomata 
are  found  roost  often  in  the  body  of  the  bones,  while  the  bard  have  a 
preference  for  the  [leriodteum.  We  constantly  see,  in  the  fascicular 
sarcomata  of  bones,  large  multinuclear  cells  (giant  cells),  which  here 
actjuire  tlicir  largest  dimenaions  :  but  the  presence  of  these  cells  alone, 
does  not  aullîce  for  the  recognition  of  a  variety  of  tumor,  oeithcr  does  it 
indicate  the  benignity  of  the  growth.  These  cells  are  mat  with  in  every 
variety  of  bone  sarcomata. 

Eucephaloid  and  fascicular  sarcomata  arc  very  often  invadeil  by  cal- 
careous infiltration,  which  does  not  change  the  gravity  of  tlie  tumor. 
The  infiltration  is  generally  in  the  form  of  nodules  or  friable  Irabeculie,

Myrnmatom  tumùr$  of  bonea  are  met  with  in  the  form  of  rouod  masses^ 
diatinclly  limited.  They  are  genorally  developed  under  the  perioâteam^ 
and  cause  an  absorption  of  the  hone  upon  which  thoy  lie.  We  have 
never  seen  them  infiltmle  the  osseous  tissue.  They  should  not  be  con- 
founded with  a  nutritive  lesion  of  the  marrow  of  bones,  which  is  seen  in 
CAchcxics  of  long  duration,  and  is  chnructerixcd  by  a  gelatinous  appear- 
ance, due  to  the  absorption  of  the  fat  from  the  adipote  cells,  which  is 
replaced  by  iteruin.  This  lesion  i«  analogous  to  that  which  occur»  in  the 
$ul>cutaDeeu.t  cellular  tissue  in  the  name  cases. 

We  have  seen  an  example  of  a  li^'/ma  of  bone.     The  tumor  was  devel- 
oped in   the  substance  of  the  tibia,  and  riuJte  large,     llie  Inbides  oCj 
adipose  tissue,  instead  of  being  limited  by  tihrous  bauds,  were  separatedl 
by  trabeculœ  of  osseous  tissue. 

Kvery  variety  of  carcinoma  has  been  mot  with  in  bones.  Well- 
authenticated  primary  carcÎDuma  of  bone  bns  been  seen,  but  secondary 
or  meln^iatic  is  much  more  fn'i[uent.  Hunl  carciiiom»  of  the  breast  of 
lon^  duration,  is  almost  alwnys  accompanied  by  secondary  growth  in 
the  vertebral  column.  The  carcinoma  is  seldom  larj^  ;  mo«t  fre- 
<]auntly,  the  os-teous  tissue  is  «ubstituteil  by  the  morbid  tissue,  for 
example,  the  body  of  a  vertebra  may  ho  almost  entirely  formed  of  carct-J 
nomatoiis  tissue,  without  its  shape  being  nokihly  changed.  There  may' 
even  he  considerable  atrophy  of  the  hones  without  either  nlceration  or 
wearing  away.  When  carcinoma  develops  in  one  or  more  vertebral 
bodici,  a  loss  of  sub>itânce  occurring,  there  is  caused  a  convexity  of  the 
column,  as  seen  in  I'ott's  disease.  The  development  of  the  morbid 
product  in  the  body  of  long  bones  or  in  their  extremities,  gives  rise  to

The  osseous   irabecnlic  included  in  the  caseous  mass  have  seldom] 
undergone  either  condensation  or  rarefaction,     Kslemal  to  the  tuber»! 
culoiia  formation,  it  is  not  customary  to  meet  with  any  considerable 
alteration  of  the  osseous  tissue,  except  rarefaction. 

The  bone  corpuscles  do  not  participate  in  the  caseous  change  of  the 
Duirrow,  (heir  nuclei  become  irregular,  but  around  the  latter  there  arc 
no  fatty  ;:niTiules.  This  may  bo  learned  by  colorinj:  with  nnilino  red, 
I  which  distinguishes  the  caseous  tran>ffurnmtion  con scijueut  upon  confluent^ 
I  tubercles,  from  that  which  accompanies  curies.  In  oriea  the  bon 
corpnsdiM  brcaV  down  by  a  fatty  degeneration,  while  the  portions  of 
bone  invaded  by  tubi-rcu1osis  not  reoeiviu)^  blood  are  necrosed,  and  <dimi- 
nation  lakes  place  at  the  time  the  crup^on  ia  completed  in  a  part.  'Hie 
élimination  very  probahly  is  produced,  as  in  a  simple  necrosis,  by 
means  of  a  rarefying  osteitis,  which  occasions  the  absorption  of  llio 
oaseotia  trabeculœ,  and  even  tlic  dc'velopmcnt  of  a  granulation  tissue. 
In  this  manner  is  formed  a  cavity  in  which  is  found  a  B0<)uestrum  sur- 
rounded by  pus. 

At  the  pr«-s«nt  time,  when  there  is  found  in  a  bone  a  canty  lined  with 
granulation  tissue  or  u  smootii  membrane  filled  wîtti  pus  or  cheesy  mate-

OuiHMoia  of  &.)i>e>  are  found  in  the  luinie  localities  as  tubercles.  It 
shouM,  bowflver,  be  remembered  Uiat  tlie  bonea  of  the  cranium  oerer 
contain  tuberculoua  gmnulationa,  while  tliey  are  a  favorite  scat  for  );am> 
nmca.  Anatomical  observations  of  ;.'un]iiiala  of  hones  are  rare  :  atlhou;;h 
clinicatlr  vrrjr  frc<i«cut.  patients  sohiom  die  of  sjrphilts.  Two  f'lnns 
occur:  in  one  ihi-y  uro  limited, resembling  in  appearance  and  Consistence 
a  hard  Burtoma  ;  in  ibc  other  they  iu6ltrate,  aa  it  were,  the  omoouh  lis. 
sue,  and  it  i«  to  tliia  latter  variety  the  name  of  gummatous  osteomyelitis 
is  fàven. 

('irntmn^ihfd  pimmata  of  the  hones  of  the  cranium  develop  flr«t 
un<ier  tfie  )(erierantum  or  beneath  the  dun  mater,  and  sometimes  even 
sîmultnneouily  at  both  of  Iheite  points;  growing  in  the  form  of  n  oooe 
into  the  oaseous  tissue,  in  wtiiub  they  occasion  a  proi;rc«sive  rarefao- 
tion.  l*liey  underj^o  albuminoid  degeneration,  and.  if  we  accept  the 
description  of  Virchow,  are  slowly  absorbed  [probably  under  the  influ- 
ence of  appropriate  treatment).  In  their  place  there  is  fonned  a  stellate 
cicatrix  of  osseous  tiiisue  derived  from  the  fibrous  tissue.  Allbough  it  is 
•c«n  from  the  di'^cription  ereu  of  Virchow  thai  theae  cicatrices  corre- 
ffpond  to  old  gunimata,  yet  this  author  dcsi;^aies  them  by  the  name  of 
dry  »}fj-fiililir  eariea.  It  is  rery  evident,  fiom  the  description  j'iven  of 
caries,  liiat  there  is  notbin;;  in  common  between  this  lesion  and  that  due 
to  syphilis.  Tliis  ^inciiiar  loss  of  substance,  truly  characteristic  of 
syphilis,  is  limited  by  a  sclero«ed  osseous  tissue,  and  at  times  by  flat 
osteophytes  which  surround  tie  eentral  depre«iioii. 

i>i^^'tiNedguraiiiata  of  bones  are  particularly  common  in  the  subcutaneous 
partA  of  the  osoeoas  system  and  palatine  arches.  Their  formation  takes 
place  under  the  periosteum  and  in  the  corrosjioudiiig  o^ueouA  tissue  at  t]ie 
same  time  ;  at  first  in  the  form  of  a  soft,  slijçfatly  getattnous,  red  tissue, 
mon  becoming  firmer  and  opuipie.  Upon  section  of  the  bone  at  tbia 
«tajre  u  whitish  surface  is  seen,  of  cheeay  appearance,  similar  to  eon- 
fluent  tiiburcles  of  bone.  But  a  very  evident  difference  may  already  he 
recogniiM-d  :  under  the  periosteum  there  exists  a  pulpy  layer,  also  whitish, 
over  a  *pace  corresponding  to  the  bone  lesion, 

A  mioroMOpic  exaniinnlton  shows  the  osseous  trabecu^as,  as  in  rarefy- 
ing oateitts  and  the  enlarged  medullary  spaces,  to  contain  gtnnmatoiia 
nodules  (see  p.  iiOO).  In  these  nodntes  the  bloodvessel*  have  remained 
permeable,  differing  in  this  re.'pect  from  tubercles.  At  the  margin  of 
the  Kurama  are  seen  all  the  characteri.flios  of  simple  osti-itis. 

What  ultimately  becomes  of  these  dîfl'used  gummata  of  lionnit?  .\n 
answer  to  this  (jiiesiion  hy  a  complete  series  of  anatomical  data  wouid 
be  desirable  :  but,  in  their  absence,  the  clinical  and  anatomical  observa,

(f/inNilrtmatit  arc  developed  more  frei|uently  in  the  osmioiis  iiamae  tliaa

substance  of  the  hone.  I'hey  may  be  diffused  or  lobulated  ;  tlie  latter 
form  is  the  most  common. 

ICvery  variety  described  at  page  128  may  be  met  with  in  bone,  for 
example  hyaline  chondromata,  lobulated  chondromata  containing  fibroiu 
trabecule  or  libro-cartiln(;'inoiis,  ossifying  clioudronata,  muoous  «hoodro- 
mnta,  with  raroifyin;;  celU,  etc. 

These  different  tumors  are  developed  u  dcsctibcd  at  page  129.  In 
regard  to  their  pro^nosiii,  see  page  131. 

Ontumata  or  tunion*  of  oiweoiis  tissue,  are  named  c](0stose«,  hy[ter- 
oflta-tes,  or  osteo|>h,vt«s,  according  to  the  shape  of  the  new  formation  upon 
tli«  surface  of  the  bone  (sec  p.  1^2).  The  name  enoatosea  has  been 
given  to  the  osseous  formations  developed  in  the  medtdlary  canal. 

In  leiicocythromia,  ti/mphatir  tumor»,  or  lymphadonoraata,  have  been 
found  iu  bone.  In  a  case  published  by  ua  in  18tî7,  the  tumor  was  quite 
larj;!!,  consistinj;  of  a  whitish  tisani-  which,  when  scraped,  exuded  a  lact*-*- 
ceiit  (liiid.  containing  cell»  analogous  to  the  whit4.i  blood  corpuscles.  In 
some  localities  the  tnmor  hod  undi'i^one  caseous  imnsformation.  A  micro- 
scopic examination  of  thin  sections  showed  the  reticulated  stroma  of 
adenoid  tiiwne.     To  the  unaided  eye,  the  tumor  resembles  a  carcinoma, 

JCj'it/ifllrjiiiaUi  'if  hiint».^ll  is  uncertain  if  there  is  ever  a  primary 
epithelioma  in  bone,  but  iia  extension  from  neighborins  tissuus  is  not 
uncommon.  An  epithelioma  of  the  lipa  may  extend  to  the  bones  of  the 
jaw,  of  the  palate  to  the  palatine  epiph  vais  ;  an  epithelioma  of  the  extrcmi- 
tiea  may  also  extend  in  depth  and  reach  the  underlying  bonca.  The  de- 
velopment of  the  morbid  mass  Is  by  epithelial  pegs,  which  penetrate  and 
develop  iu  an  embryoino  tissue  fonncd  at  the  expense  of  the  osseous  tissue, 
a»  in  osteitis.  (See  p.  It'T-')  Tubular  epithi-lîojuHta  arc  met  with  in  bones, 
being  not  nnconimoii  in  the  niiperior  maxillary, and  they  are  then  consecu- 
tive trt  tumor»  of  the  soft  ]ialaie  or  maxillary  sinuses.  A  case  of  cylindrical 
epithelioma  has  been  re|>orted  by  Oawrilofi';  this  ia  not  surprising  when 
it  is  remembered  that  these  epitheliomata  behave  as  carcinomata  in  their 
generalization.

is  often  impossible  to  indicate  exactly  where  it  ceases. 

At  the  periosteal  surface,  the  spongoid  layer,  especially  at  tlio 
of  the  diitphyfis.  is  mingled  with  a  tissue  forinen  of  oeseouit  Unwli

I     A  microscopic  examination  of  fn»>h  sections  of  the  traboculie  of  tl

[  uiar  non-laminated  substance.     These  corpuscles,  larger  than  boue  cof 
[nasclcs,  do  not  preaent  any  anaatomoeing  canalicuU  at  their  mari^n*. 
To  understand  the  importance  of  the  tissue  which  form  the-sc  trabec»la^, 
their  fonnntion  from  hyiilino  curtilage  must  be  traccit.     There  is  ()ien 
seen  starting  from  tiiis  eurtilnge  a  calcareous  infiltration  of  tlie  segmented 
fundamental  eubstancc  which  separates  the  Urge  eorpHMles;  (liis  cal- 
careous infiltratiou  extend»  to  the  secondary  capsule  (which  never  ia  the 
ease  in  physiological  os»ilication);  it  results  in  the  whole  cartilaginous 
tiitsue   being  invaded  by   catcaruous   granules,  which  remain   distinct, 
,  that  is,  separated  by  cartilaginous  tissue  whioh  preservea  its  fiexibiliiy. 
[The  secondary  capsules  are  not  dissolved — an  essential  dilterenco  from 
I  physiological  os.4ttication.     At  the  same  time  that  this  calcareous  incrust- 
tatîon  occurs,  tlie  vascular  canals  of  the  cartilage  arc  vnlarged  by  the 
^dissolving  the  calcified  tissue  which  surrounds  them,  untdng  with  each 
other  and  opening  into  the  medullary  spaces  of  the  old  bone.    By  tbeii^ 
union  they  form  a  cavernous  system  to  tte  later  studied.  ^Ê 

The  spongoid  tissue  is,  therefore,  formeil  of  trabecule  representing 
portions  of  cartilaginous  ussue  infiltrateil  with  calcareous  salt'*.  These

These  trabeculie  arc  the  analogues  of  Shnrpey's  fibres,  which  arc  seen 

in  tilt?  osstficalion  of  ihc  sopondary  bone»  of  tho  cranium  ;  thoy  differ  from

not  difl'er  from  jtraumatic  arthritis  artifteially  provoked  in  the  higher 
animals. 

^VlIen  an  inflamed  articulation  is  opened,  there  Sows  from  it  a  viscid 
ropy  fluid,  the  amount  and  appearance  of  which  vary  according  to  the 
decree  and  duration  of  the  inHammntion.  In  eomc  eases,  this  fluid  re- 
sembles the  normal  synovial  fluid,  hut  is  more  abundant  ;  like  synovia,  it 
coagulates  by  tlie  addition  of  acetic  acid  ;  it  contains  a  laigc  number  of 
cellular  elements,  some  of  which  resemble  pus  cells,  other*  much  laT^cr, 
are  round,  and  contain  one  or  more  vesicular  nuclvi.  In  llio  protoptasn 
of  these  cells  fatty  granules  are  generally  seen,  which  aometimes  are  very 
abundant,  and  the  cell  then  has  the  ajipearance  of  a  granular  body  (cor« 
puscle  of  GluRc).  The  synovia  is  more  or  less  cloudy,  depending 
upon  t)ic  number  of  cellular  elements  and  the  degree  of  ibeir  fatty 
change. 

There  are  usually  seen  in  the  liquid  mucous  flukes  similar  to  sputa.

In  t)ic  i>liyAi(ilo^ctil  ittntc,  hencath  the  proHfcrtttinfç  cartilage,  in  foind 
ft  tliiii  layor,  forined  of  areolar  tissue,  tlie  trabeuul»  of  whtcli  are  wtn- 
posed  of  the  fundamental  ïiuliHtftiice  of  cartilage  intlltrated  with  calcareooaJ 
saltii  ;  the  alveoli  containing  erobryooal  marrow  and  vesaelii.     Iteneathl 
this  the  tnie  osseous  tissue  is  formed.     To  this  layer  is  given  the  name 
of  ossiform,  bone- forming. 

In  rachitis  vre  do  not  think  with  Broca,  that  it  is  a  simple  incrvaso  of 
tthin  layers  of  bone,  but  thorv  is  formed  upon  its  surface  a  peculiar  titwio,j 
fio  which  Gatfrin  gave  tiio  name  of  »fntH,f»<l.    Tiiis  tissue,  which  oftelt^ 
extends  from  tlie  niar;^n  of  the  citrlila^  to  the  diuphysis,  frci|UOnUy 
invading  both,  \«  rvd,  formed  of  alveoli  of  very  irregular  itinK-iuioiis  i 
it  appears  to  eontain  much  hloml,  iw  ooiksistvnve  is  that  of  a  tin«  spong6|'| 
or  botter,  tliat  of  the  osseouH  tissue  of  the  e]>iphysiH,  which  ha«  boeiH 
ÏDComplotely  «oftcncd  1>y  an  acid.     The  lonndary  Wtween  tliis  «itongoiiU 
tissue  and  the  cartilage  \»,  very  diiltnct.     At  times  small  inlands  of  hya- 
line carlilaipe  are  found  in  its  interior.     On  the  side  of  the  old  Itone,  it 
is  oflvn  impossible  to  indicate  exactly  where  it  ceases. 

At  the  periosteal  surface,  the  spongoid  layer,  especially  at  the  margin 
of  the  diaphyais,  is  mingled  with  a  tissue  farmea  of  osseous  ]am«)MBji 
separated  ^m  each  oUicr  by  a  soft  tissue,  of  which  we  will  presontlj^ 
speak. 

A  microscoiHC  examination  of  frueli  soctione  of  tho  trahccuttc  of  the 
spongoid  tissue  shows  angular  corpuscles  arranged  irregularly  in  a  gran, 
ular  non-laminated  sulutanoe.     Tliese  eorpuscle.<,  larger  than  Imne  cor- 
puscles,  do  not  present  any  anastomosing  canaliculi  at  their  margins. 
To  understand  tho  importance  of  the   tissue  which  form  these  trabeculie, 
their  formation  from  hyaline  cartilage  must  be  traced.     I'liere  is  then 
seen  starting  from  tliis  cartilage  a  calcareous  intiltration  of  tho  segmented 
Lfundamental  substance  which  separates  tho  large  corpascles:  this  caU 
EjCarcous  infiUruliou  extends  to  the  secondarjy  capsule  (which  never  is  the 
BBOse  in  physiological  ossification);  it  results  in  the  whole  cartilaginous 
>iissu«   being  invaded  by   calcareous   granules,  which  remain   distinct, 
that  is,  separated  by  cartilaginous  tissue  which  proscrvcv  îtx  flexibility. 
The  secondary  capsules  are  not  dissolved — an  essential  diflcrcnce  from 
physiological  ossification.     At  the  same  time  that  this  calcnreons  incrust- 
ation occurs,  the  vascular  canals  of  the  cartilage  are  enlarged  by  the 
disAolviug  the  oaluiticd  tLssne  which  iiurrnuiids  them,  uniting  with  each 
oitier  and  opening  into  the  medullary  space»  of  the  old  bone.     Ky  llieir 
union  they  form  a  cavernous  system  to  be  later  studied. 

The  a|K}ngoid  tissue  is,  therefore,  formed  of  Irabeeulie  repreaenting 
Lportions  of  cartilaginous  tissue  intiltrated  with  calcareous  salts.  These 
^rabeculie,  when  young,  permit  the  cartilage  with  its  capsules  to  be  dis-J 
tinguisbed — the  margins  of  the  latier,  however,  ai-e  difficult  to  recognise^ 
owuig  to  the  calcareous  incrusmtion.  In  older  trabeculte,  the  capsulea 
are  entirely  hidden,  but  in  order  to  make  them  visible,  it  suffices  to  dis> 
solve  the  calcareous  sall«  wiih  hydroehloric  or  chromic  acid.  It  may 
happen  that  these  reagents  do  not  reveal  the  presence  of  cartilaginot

more  consistent,  the  crlU  become  «tellate,  and  separated  by  a  slightly 
Sbiillaled  fuixlninontil  suhittitiico. 

Tbia  attempt  at  fibrous  or^anixaUon  of  the  marrow,  takes  place  not 
only  in  tlie  medullary  cavities  formed  duriiij;  the  evolution  of  rachitis, 
in  tlie  old  marrow  contained  in  the  Hj)on^  tissue,  in  the  llavenuan 
ànaU.  in  the  central  canal  and  in  the  fiiiKperiosteal  marrow. 

In  liie  me^lollary  canal,  the  peripheral  layers  of  the  marrow  are  those 
which  arc  th«  moet  modified.  While  tlie  central  portiune  of  the  marrow 
arc  red  and  fluid,  composed  of  embryonic  marrow,  the  peripheral  portioits 
arc  orgiinixed  into  a  kind  of  younj;  connective  timue,  nhicb  has  the 
nppenrnnce  of  a  tnednllary  membrane.  It  a  posriblc  tliat  it  W114  this 
condition  which  leil  the  old  anatumisttt  to  admit  the  existenco  of  a  me- 
dullary memhraue.

a  eofi  connective  tissue  ;  later  it  becomes  more  solid,  adheres  to  the  under 
surface  of  th«  poriostoum  and  to  the  bone,  so  that  its  separation  from  the 
bone  is  much  more  difficult  than  is  customary  in  youn^  persons.  UTiia

of  Tihich  is  not  determined,  consisting  in  the  appeanincc  of  waving  refract-

Thi»  fatty  degeneraiion  cause.*  tlie  deatti  of  the  cellular  elements  of 
the  csrlila;;e,  »o  that  in  a  cartilage  vrlicre  it  in  jire^ciit,  there  is  seen, 
indiead  of  die  capaule  and  cell,  iKmal)  collections  of  fatty  grannie».  The 
interoieiliale  famlafoental  substance  is  softened,  often  cracked.  Tbia 
alteration  is  primary  ;  it  does  not  belong  to  inflammation ,  wbich  in  car 
tila^G  is  characterbted  by  an  opposite  pbenomenon,  the  disappearance  of 
the  fat  contained  In  the  cells. 

A.  Infiltration  of  urate»,  which  begins  in  tlic  cells  of  tlic  cartilage,  has 
been  already  inentiimed,  page  .V2,  and  will  be  fully  explained  under  gout. 

Lesion»  of  nutrition  which  affect  the  fundamental  aubittanco  are  :^ 

c.  Mucoi<l  degeneration  occur»  physiologically  in  the  coalal  cartilagea 
(see  p.  44),  and  may  occasionally  occur  in  other  cartilages  ;  it  ia  usually 
accompanied  by  a  segmentation  of  the  fumUmental  auhsLincc, 

d.  Calcareous  infiltration,  wIiil-Ii  is  the  reverse  of  iniiltnition  of  urates, 
begins  always  in  tlic  capsules  of  the  cartilage,  and  extends  into  the  funda- 
mental substance,  never  invading  the  cells. 

t.  Infiltration  of  urates  into  tbc  fundnmuuttd  substance;  it  consista 
in  the  formation  of  crystalline  needles  of  urate  of  soda. 

Lttiotif  front  irritatviH  of  the  cartilage  are  e3(plaine<I  by  the  modifi- 
cations which  occur  at  the  »ame  time  in  thu  cells,  in  the  capsules,  and  in 
the  cartitannous  substance.  lu  mo*l  i!a.<«e.'<,  as  the  cells  within  the  cap- 
sules are  divided,  they  generate  arouwl  them  new  cartilaginous  cansules  ; 
but  it  also  hanpens  at  times  tliat  the  celU  which  result  from  the  division 
of  the  old  cells  have  lost  the  properly  of  forming  new  cajisules,  and  then 
they  remain  in  tbc  state  of  embryonic  cella.  This  last  phenomenon  is 
sceu  in  casus  where  the  irritation  is  very  intense,  or  when  it  is  associated 
with  calcareous  inRltration.  The  embryonic  cells  which  result  from  this 
proliferation  remain  as  such,  or  they  become  tlie  point  of  origin  of  an 
osseous  or  fihnms  new  formation. 

These  lesions  arc  essentially  similar  to  (hose  occurring  in  cartilage  in 
the  jiroximity  of  pointa  of  ossification. 

The  ])henomena  resulting  from  this  process  vary  a  little,  according  to 


226 


the  cartilaKC3  affected.  In  the  diarthrodial  articalatîons  tb«  cartîlazes 
arc  frcf  at  tht-  articular  eiirfacc,  and  an;  not  there  covorwl  by  a  peri- 
chondrium :  thcro  is  then  Mt'n  upon  this  eurlaco  a  scries  of  altérations, 
which  will  he  il«scribcd  under  auuttf  and  chronic  artliritia. 

'VVIion  the  cartitngcs  nru  covered  hy  a  filirous  membrane,  a«  llie  carti- 
lage«  of  the  larynx,  the  coital  cartilages,  and  tlie  intervertebral  disk», 
the  cells  of  ttie  cartilage  mullijily,  and  «re  surrounded  alwaya  by  »eci>i»- 
dary  capaaica,  giving  rise  to  the  formntion  of  neir  inasnoa  of  cartila;^. 
It  then  almoat  constantly  h&pneua  that  the  irritation  terminates  in  a  true 
Oif^iBcatton.  This  i§  noticed  particularly  in  the  thvroid  cartilage  of 
voun^  persons  eufleriug  for  several  year»  with  phtliisis  ;  tlie  ossiHcation 
IS  hero  caused  hy  a  process  nmilar  to  that  of  physiolor^ical  ossification. 

A  slight  CO DÙnuous  irritation  of  cartilage  ainays  terminates  in  OSWOHB 
new  fonnations.  The  facility  with  wliich  the  os«iticiition  of  pndifvratiii; 
C-nrtila;^  oceura  explains  why,  in  fractures  of  the  ooetal  cartilages,  the 
ealhia  is  frei|ucntly  entirely  osseous.  It  has  been  previously  stnttxl  tliat, 
in  fractures  of  the  costal  cartilage*,  the  irrilution  supervening  at  the  end» 
of  the  fragments  occa.iion»  iutlamniatory  changeit.  The  fundamental  sul>- 
slance  ia  inhltrated  by  calcareous  aalta  ;  the  {irlnmry  capHulcn  are  greatly 
enlarged  and  conimuuicate  witli  one  another;  the  celU  become  free  in 
the  intonor  of  these  cavities;  the  formation  of  marrow  and  of  hone 
takes  place  in  a  pbyeiological  manner.  Ttic  formation  of  osaeona  tissue 
in  fraeturcs  of  cartilage  is  tndy  a  singular  occurrence,  for,  subneri- 
chondrial  resections,  made  hy  >l.  I'eyraud,  always  gave  bim  cnrti1agi> 
nous  regenerations,  iiuppuration  of  the  wound  which  extends  into  the 
resection  does  not  ])revent  the  regeneration  of  the  cartilage  which  takes 
place  from  the  pi-eserved  perichondriutn,  the  regeneration  contribnting  to 
lom)  the  wall  of  the  abscess.  Tlierefore  suppuration  does  not  prevent 
the  new  formation  of  cartilaginous  tissue  any  more  than  it  does  the  for- 
mation of  osseous  callus  in  a  compound  fracture. 

There  arc  tumors  developed  from  pre-existing  cartilage  which  are 
composed  of  cartila^noas  tissue.  By  their  slow  develojiment  and  llioir 
unimportance  they  are  entirely  separated  from  cbondroniuta  projicr. 
These  cartilaginous  funiiations  arc  named  eccliondro«CB,  iiml  arc  found 
must  fre<iucntly  in  arthritis,  under  nliicb  they  will  he  described.

Prrtioo»  to  beginning  tlic  imtttotnical  study  a{  articular  nfToctïoQS  H 
is  cxiicilicnt  to  prt^,  in  •  coiiuisc  maniwr,  tlic  «tnicttiro  of  th«  most 
imjiortanl  ]iart«i  which  enter  into  the  composition  of  joint*  in  n  normal 
slat*.  'Hii-  cavitie?  of  the  fliarthroiiiat  articulations  are  limite<l  by  the 
surfaces  of  the  cartilagca  and  the  synovial  membrane.  The  elements  of 
the  (liarthrodial  cartilages  have  an  unvaried  arrangement.  When  a 
transverse  «ection  of  these  cxrlilnjie.'i  is  made,  there  is  seen  a  ntimîier  of 
superimposed  lavers  in  regular  order.  At  the  free  surface  tiie  capsules 
are  flut  and  lenticalar  :  beneath  these  the  capsules  are  round,  containing 
only  one  cell  like  the  proccdin)*  ;  deeper  the  capsulea  are  lcn;;thened  per^ 
pcndicularly  to  the  surface,  and  contain  two,  three,  or  a  greater  number 
of  seooDdary  cap^uli-x  placed  one  behind  the  other.  The  enlarged  pri* 
mary  capeulcs  form  linear  série»  nhioi)  arc  contintted  into  tlio  deepest 
layers,  where  there  ia  an  infiltration  of  calcareous  salts,  uniting  tlte 
hyaline  cartilage  with  the  osaeoos  tioâue.  .\ll  the  celU  contained  in  the 
capsules  at  the  surface  and  in  the  middle  laver  inclose  granules  and  even 
drops  of  fat.  The  calcified  layer  is  bDun<te(l  on  the  cartilage  side  by  a 
sinuous  line  :  on  the  bone  side  are  hollows  and  prominences,  in  which  6t 
papillary  prolongations  from  the  extremity  of  the  bone.  In  the  centre  of 
each  of  these  omvous  papillic  there  exists  a  medullary  and  vascularcarity 
in  communication  with  the  medullary  And  vMcnIar  ^Mue  of  tho  spongy 
siiWlJtncv  of  the  bone.  If,  therefore,  the  plasma  of  the  vcwels  jçoes  to 
the  hyaline  cartilage,  it  must  ])aM  throu-;!]  the  osseous  layer  ami  the  layer 
of  calcified  cartilage.  Yet  these  la.«  layer*  do  not  contain  canals,  and'  do 
not  appear  permeable  ;  so  that  the  nutritive  material  reaches  the  cartilaj^' 
to  some  otlier  way.  Very  probably  the  nutriment  comes  fi-om  the  tiuîd 
which  bathed  the  articular  surfaces,  and  which  is  exuded  from  the  res^els 
of  the  synovial  membrane. 

TI»o  synovial  mcmliranc  presents  for  consideration  a  plane  soiface  and 
a  villous  surface.  The  plane  surface  is  composed  of  layons  of  fibrous 
tissue  intemtinglcd  with  numerous  claetlu  fibres,  id  continidty  with  the 
periarticular  connective  tissue,  and  lined  with  a  single  layer  of  flat  epi- 
thelial celts,  rcKembling  those  on  the  large  «crou»  membranes,  'llie  villous 
surfaces  named  synovial  fringes,  are  especially  seen  at  tlic  points  where 
tlie  memkrnno  fonns  folds  in  order  to  pass  from  one  surface  to  another. 
Their  base  is  constituted  hy  two  supporting  layers  of  the  synon&l 
membntne,  resembling  the  peritoneum  where  it  form»  the  meisontery. 
Between  the*;  two  byem  there  are  found  loose  connective  tissue,  groupa 
of  adii>03e  cells,  and  numerous  bloodvessels.     Alt  of  these,  on  account

«red  by  two,  tlirec,  or  more  layers  of  epithelial  celln.  The  latter  are  pro- 
vided with  prolongations  which  join  them  toother,  and  contain  nuclei, 
tlie  membrane  of  which  presents  a  double  contour.  This  epitlieliuro 
Kftemblea  very  closely  that  seen  upon  the  choroid  plexus.  At  tiiMS  tli« 
prolongations  have  the  shape  of  a  elub,  covered  with  a  similar  layer  of 
epithelium  :  their  axis  formed  of  connective  tissue  frequently  contains 
CBrlila;;c  capsules.  VtsseU  arc  never  found  in  the  prolongations.  At

fringe,  there  are  seen  one  <ir  more  vnsculiir  hriuiches, 

The  pbysiohigical  function  of  the  synovial  fringes  i»  very  important, 
'ilie  cellrt  which  cover  the  prolon^rations  are  the  true  organs  for  secretin;; 
the  synovial  tluid,  and  (he  large  and  niuuorous  vessels  found  in  the 
frinj!;es  carry  the  material  for  this  secretion. 

'Ilie  synovial  membrane  does  not  cover  the  surface  of  the  diarthrodial 
cartilages  at  the  (mints  where  the  cnrtilu^cea  slide  uiion  one  (mother.

scope, appcant  ns  granules  and  small  drops.  Kpithelial  cclU  and  cells

^Yhcn  an  inflamed  articulation  is  opened,  there  Hoirs  from  it  a  viscid 
ropy  fluid,  the  amount  and  appearance  of  which  vary  according  to  the 
degree  and  duration  of  the  itiflnmmation.  In  some  cases,  this  fluid  re- 
sembles the  normal  synovial  fluid,  but  ia  more  abundant  ;  like  synovia,  it 
coagulates  by  the  addition  of  acetic  acid  :  it  contains  a  targe  number  of 
cellular  clcmeuts.  some  of  which  resemble  pus  cells,  others  much  larger, 
are  round,  and  contain  one  or  more  vesicular  nuclei.  In  the  protoplasm 
of  these  cells  fatty  granules  are  generally  seen,  which  sometimes  are  very 
abundant,  and  the  cell  then  has  the  upjioarance  of  a  granular  body  (cor- 
puscle of  Uluge).  The  synovia  is  more  or  lew  cloudy,  depending 
upon  the  «umber  of  cellular  elements  and  the  degree  of  their  fatty 
change.

of  the  diarthrodial  cartila;;e  is  coiisi&ntt/  seen.  For  this  rcawn,  vre 
object  to  the  names  of  svnovitis  and  st1^raiDeniD|riti8,  given  by  Volkmann.

As  seen  in  tranaverse  sections,  the  superficial  lenticular  canali 
which  Inclose  the  cellular  elements,  nat  very  diiitinct  in  the  normal  state' 
(eee  p.  2-T),  are  the  first  to  bo  intluenced  by  the  inl1amroa[<ory  irritation. 
The  protoplasm  of  tliese  cells  Hwelli',  the  nuclei  increase  in  sise  and 
become  vesicular.  A  very  diittinct  nucleolus  apneare;  tlie  capsules, 
which  were  flat,  bccomo  spnerical.  (Fi;;.  1:12.)  By  the  application  of 
picnc  acid  upon  fresh  pieces,  all  these  changes  are  rendered  v^ry  mani- 
fest, as  i»  e.\m  the  division  of  the  nucleus  which  involves  the  scj^ncnta- 
lion  of  the  jiroloiilasni.  The  capitule  may  at  one  time  contain  si-veral 
«ells,  but  soon  each  cell  is  inclosed  in  a  secondary  capsule,  so  that  the 
lenticular  capsulée  of  the  surface  which,  in  the  phyaiolofçwal  statefj 
never  contain  more  than  a  single  cellular  lams,  enveloj)  now  two  or  a. 
greater  number  of  secondary  capsules.  Most  writers  who  have  remarked 
this  phenomenon  (Kedfem,  V.  Weber,  etc.)  in  chronic  arthritis  only, 
have  taken  the  secondary  capsules  for  the  cells.  This  mistake  may  be 
avoided  if  »  flolnlinn  tjf  iodine  19  addivl,  which  colors  thu  jiroMploani  of

This  increase  of  the  superficial  cellular  elementt  generally  does  not 
incKnle  the  whole  extent  of  the  inve^tln;^  cnrtila;;»,  hut  i^  seen  in  dis»em>

deep  U^^erj  and  even  the  calcified  layers  of  the  cartilage.     The  ncir- 

formed  oelU  an<l  the  formation  of  secondary  capi)uleii  do  not  differ  froni 

those  described  in  the  superficial  layers.     Since  the  primary  camules  of 

tbo  midtlle  layers  are  arran^^cd  in  a  linear  maitocr  and  preasea  a^inst 

.one  another,  they  are  elongated  and  form  rows  perpendicular  to  the 

[surface  of  ihc  cartila);«,  while  ihe  lenticular  capantcs  of   the  surface 

tro  filled  with  sccondury  capsules,  forming  lines  wfaicb  have  a  i^roctioa 

[parallel  to  the  surface. 

The  proliferation  of  the  cclU  is  always  accompanied  by  a  segmonta- 

ktioD  of  tJio  fundamental  8uh«lAnce  between  the  primary  capsules,  caii^ng 

fatriio  jMirallcl  to  tbo  long  axi«  of  the  jn-iraary  «apaulvx  (nee  fig.  ]'.V2).

surface,  while  in  the  superficial  layent  it  iit  jiarallcl. 

In  an  advanced  s[a)!;e  of  the  disease  the  striie  give  rise  to  cleHa,  which 
dinde  the  cartila^'e.  as  if  an  incision  had  been  made  with  a  knife.  These 
[incisions  are  parallel  to  the  surface  in  the  superlicial  layers,  and  perpen- 
dicular in  the  deep  layers.  This  change  in  the  cartilage  may  be  con- 
founded  with  the  villous  state  of  chronic  rheumatism,  frocn  which  it 
notably  diffeiy,  as  will  be  later  seen. 

These  clefts  which  end  t)io  «cgmentalion  of  the  cartilage  may  ecpa- 

Irate  it  in  shred.'<  parallel  or  ohli<iue  to  the  surface,  and  may  therefore  he 

'  larger  than  the  thickness  of  the  cartilage.     Very  freipiently  these  shreds 

Unclose  proliferating  cellular  elements.     When  a  true  ulceration  of  the 

cartila;i:e  supervenes,  the  fundainc  iit.il  substance  sofiena,  untlergoes  a  kind 

of  liipie faction,  and  the  proiiteralcd  cells  become  free. 

From  this  description  it  is  seen  that  in  aculo  arthritis  the  diarthrodial 
cartilftgcs  are  affected  as  well  as  the  synovial  membrane;  lesions. aro 
I  produced  in  the  cartilage  at  the  same  time  as  in  the  synovial  membrane. 
I  Vet  the  hyperniniia  and  exudation,  which  have  their  origin  in  the  vessels 
'  of  the  synovial  mcmbnuie,  pluy  an  important  role  in  the  inflammatory 
I  lesions  of  Uie  cartilage.  It  hn»  been  shuwn  that  the  superficial  cell*  of 
I  tliQ  cartilage  are  the  fir^t  alfected.  This  may  ho  attrihuiod  .to  the  cir- 
Icumstance  that  they  are  in  direct  connection  with  the  exuded  liijiiicU, 
tfrom  which  thev  draw  their  nutritive  material.  It  has  been  seen  liiat 
[tlie  nutritive  material  of  cartilage  is  not  derived  from  the  vessels  of  the 
[hone,  since  tbo  calcified  layer  of  the  carUlage  prevenia  it.  The  cellular 
I  elements  of  cartilage  have  in  arthritis  an  individual  aclirity;  fop,  al- 
rthongh  all  may  beiijU.illy  surrounilod  by  tholiijuid,  yet  all  do  not  eigually 
par^cipate  in  the  proliferation.  This  is  very  important,  because  at  the 
prci^ent  time  there  arc  some  pathological  anatomists,  who  are  inclinuil  to 
■^aeny  anv  creaiivv  adivity  to  the  cellular  elements  in  inflammation.

In  a  few  ca^e.t  of  purulent  arthritis,  lesion»  more  or  le»8  advnncoil  of

Bmsli  part  of  the  surface  of  one  of  the  condyles  of  the  femur  was  coveredl 
by  cartilage.     The  rest  of  the  nriicnlating  surface  belonging  to  llio  bone

A  caicroscopical  oxaminntiou  of  a  vertical  section  of  the  remaining

The  mo.st  superficial  rows  opened  upon  the  jturfnce  into  a  purulent

This  forra  of  arthritis  is  very  oommon.  The  articular  cartilaginous 
covering  U  very  notably  aifected,  while  the  synovial  membrane  does  not 
present  any  appreciable  lesion.  The  diacnse  supervenes  in  llie  articula- 
tions corresponding  to  the  two  extremitiea  of  a  bone  attacked  with  inliam- 
mation,  or  a  rapidly  growing  tumor  (sarcoma,  carcinoma,  etc.).  When 
an  articulation  is  invaded  by  a  suppurative  inQsmmation.  as  seen  in  the 
««■cond  pcriwi  of  white  swellings,  and  when  the  corresponding  bones  are 
affected,  then  the  neighboring  articulations  present  Uic  lesions  to  bo 
described. 

The  articulating  cnvily  does  not  contain  more  than  tlie  normal  amount 
of  fluii).  The  synovial  membrane  is  generally  slightly  hyj>enemic;  iW 
Triaitfi»,  however,  may  present  a  very  marked  congestion. 

llie  cartilages,  and  es|>eeial1y  those  which  corresf>ond  to  the  diseased 
bone,  are  more  or  less  deeply  eroded,  the  surface  ia  bare  or  covered  by 
»  connective  tissue  of  new  formation.  The  shape  of  those  erosions  u 
tisnally  very  irreKtilar,  their  size  varies,  they  arc  located  chiefly  at  tho 
periphery  of  the  cartilage,  thus  reaching  the  margin  of  the  synovial 
mcmbmne;  but  solitary  or  confluent  erosions  arc  frci{uently  seen  i»  tho 
centre  of  the  cartilaginous  surface.  The  loss  of  cartilnge  at  tlio  periph-

capsule,  the  cells  of  which  have  become  f^e,  and  have  floated  on  in  the

cells  may  give  origin  to  an  embryonic  connective  tiwne,  especially  trhon 
the  erosions  are  in  connection  with  the  conncctire  tissue  of  the  Byno\ial 
membrane  ;  the  veaaels  of  the  aynovial  membrane  enter  into  tlie  luiildlo

tmitli»  arc  ^tven  to  distinct  clinical  affections  ;  yet  the  anatomical  lesions 
and  evolutions  are  the  same  in  those  different  maladies.  They  are 
easenlially  characterised  by  a  villous  state  of  the  cartilages,  by  a  hypo^ 
tr-Jpliy  of  the  synovia!  fringes  ami  by  ecchoiidroaea  or  oâteophytea  in 
the  circumference  of  the  carlila'^inoiis  covering;  these  serious  legions 
arc  not  accompanied  by  any  notable  effusions  into  the  articular  cavities. 

The  lesions  of  clironic  rtieuroatiam  differ  acconiing  to  the  articulations 
affected,  and  according  to  the  sta;;t>  of  the  disease. 

In  the  phalangeal  articulations,  for  example,  the  changes  consist  in  the 
pnigressivc  disappearance  of  the  centre  of  the  cartilage  by  the  villouA 
traiHfnmmtion,  which  will  be  described  later;  afterwards  small  cartila- 
ginous ncjiluU'»  (ecchou'lro«e-*)  arc  develojicd  at  thy  margin  of  the  car- 
tilaginous covering.  These  give  to  the  digital  articulations  a  peculiar 
appearance,  which  has  cause'l  the  disease  to  be  named  nodular  rfaen* 
matism.  At  a  more  advanced  stage  of  the  disease,  the  central  parts  of 
the  cartilage  bare  di»ap[>eared,  and  the  eccbondrowes  have  become  ossified. 
In  these  caaos  the  articulating  surfaces  formed  by  an  eburnated  osseous 
layer,  hare  lost  their  original  form,  and  present  furrows  or  grooves,  which 
may  be  determined  by  articular  movements. 

Ill  the  large  articalatioiis,  as  the  knee,  there  is  seen  the  samo  disap-

'llie  liistoloi^ical  lesions  in  chronic  rheumatism  have  been  studied  by 
Redfem.  i.i.  Weher.  \'olkfnanii,  etc.  These  authors  have  distinctly  seen 
what  takea  place  at  the  centre  of  the  cartilage  in  pnasing  into  the  viHon» 
state  :  t>iit  they  have  not  understood  the  change  in  the  cartilage  at  its 
periphery  rcsultinj;  in  tho  formation  of  eccbomlrosos.  Throughout  tho 
whole  extent  of  the  cartilsgc  there  is  seen  in  perpendicular  sections  s 
multiplication  of  the  cells  of  the  cartilage,  with  the  formation  of  cansnles 
around  each.  Tlic  enlarged  primary  capsules  contain  a  large  number  of 
secondary  capsules.  Very  olten  these  secondary  capsules  form  groups 
enveloped  in  a  conmion  capsule.  In  Other  cases,  the  primary  capsule  is 
filW  with  small  round  capfule»,  which  arc  not  held  together.  Former 
writers  have  taken  these  round  capsiile*  for  true  e«-ll8.  Tliis  error  niny 
be  avoided  by  the  employment  of  a  Aoliilion  of  iodine,  which  coIori  tho

En  the  majority  of  caMH  it  is  difficult  t«

layers  of  the  bone  occurs.  Yet  we  have  ob«

process.  While  the  superficial  csiwnle*  of

calcified  layer.  Tin-  omcous  trabeculic,  which 
separate  lliera  from  the  medullary  cavities, 
are  in  their  turn  absorbed  by  a  process  similar 
to  that  seen  in  osteitis,  and  finally  the  enlarged  capsules  open  into  the 
medullary  spaces  of  the  bone.  The  cells  contained  in  capsules  are  emptied 
into  these  spaces,  as  the  superficial  capsules  are  emptied  into  the  articular 
cavity.  As  a  consctjucuce.  the  medullary  spaces  which  bonier  on  the  in- 
vesting cartilage  are  filled  with  ncwlyformcd  cells  developed  in  the  cartil-

from  the  circumstance  that  the  mar- 
gin of  the  articular  cartilai^c  id

of  one  of  the  ecebiindro5e«  shows  suc- 
«esuvely,  first  a  fibroos  tiwne  membrane,  then  fibro-cartilft;;ioous  tissue, 
and  finally  pnjlifcmtin;;  hyaline  cardlage.  The  fibrous  membrane,  which 
is  in  some  cat^vs  di*tiiiL'l1y  vucculnr,  varies  in  thickness,  and  is  diri-ctly 
continuous  with  the  synovial  membrane  and  periosteum.  Beneath  is 
seen  a  (ibro^;artitaginous  layer  which  uiiit«s  it  to  the  hyaline  cartilage. 
This  hitter  incloses  large  capsules  with  secondary  capsules,  forming  by 
their  union  a  complicated  System. 

Thi?  ti-taue  has  a  very  close  analogy  to  the  carlilnginoua  layers  which 
precede  ossification  in  the  short  bones.  The  ecehoudroses,  however,  become 
omified  in  time,  the  ossification  always  beginning  at  their  baae.  and  from 
the  old  bone.  The  process  is  similar  to  physiological  ossification  (see  p. 
28).  TTic  osseous  tissue  invades  the  ecchomlrosis,  which  finally  disap- 
pears, in  order  to  give  place  to  a  spongy  or  eburnatcd  osteophyte.  In 
chronic  rheumatism,  the  OBt«opliytc  is  usually  fburiiated  only  upon  the

ftUFji^ons  have  described  white  swelling  without  defining  it  either  clinic- 
ally or  anatomicnlly.  Their  descriptions  indiiilc  several  forms  of  artic- 
ular ilisertse.  Clinically  they  designate  under  the  iiamc  of  white  swelling 
all  chronic  articular  atTcctioiis  having  a  tewleuoy  Ut  suppurate,  or  wliieh 
are  suppurating. 

The  i^wellin^  ami  the  pallor  of  the  integumenti  aUo  enter  into  tbe  elio- 
ical  detiniliou  tliat  ha.4  been  given  hy  them,  altliougU  they  reoogniie, 
that  in  certain  stages  of  while  swelling,  the  skin  and  subcutaueoos  tissue 
may  be  the  seat  of  an  inllnmmalion  accompanied  by  redness. 

In  this  disease  ihey  have  pointed  out  all  the  possible  alterations  of  tlie 
synovial  membrane,  of  the  cartilages,  and  of  the  bones.  Bonnet  is  the 
only  author  who  has  endeavored  to  find  in  white  swelling  a  constant  ana- 
I  tomic!il  chanicter  in  the  existence  of  fungous  granulations  of  the  synovial 
Inacnibrani;  and  bones.  liut  these  granulations  do  not  exist  in  all  the 
iMagtfs  of  white  swelling,  mid  they  do  not  diflbr  from  large  gianulatioita 
rdevelopcd  elsewhere. 

In  the  clinical  course  of  this  affcotion  there  are  generally  two  periods  ; 
the  first  long,  characleriised  by  uneasiness  or  slight  pain  ;  the  smoikI  iu- 
dicated  by  the  cousopiences  of  suppurative  intlammation. 

The  anatomical  lesions  of  white  swelling  differ  in  the  two  atngesof  tii« 
disease.     In  the  firet  stage,  tliey  consist  in  a  fatty  degeneration  of  the 
cells  of  the  cartilage,  and  very  often  of  the  bone  cells  of  the  epiphysis.!

the  cartilage,  a  concrete  mucotu  exudation,  graj'iMi  and  gelatinous, 
which  upon  section  showed  a  very  Iiandsome  network,  in  the  meshes  of 
which  was  found  a  liquid  subétance  destittite  of  cellular  elements.  The 
exudation  was  adherent  to  the  surface  of  the  cartilage. 

Tlie  cartila^fs  had  preaerved  their  polished  surfaces  :  they  were 
slightly  oi>!v.iiie,  and  baa  lost  a  little  of  their  elasticity.  V«nical  s<tc- 
tiona  examined  under  the  microscope  show  all  thi-  layera  succvsaivoly 
described  on  page  '2'27.  The  cells  contain  fine  fatty  granules,  and  some 
an  completely  destroy«d  by  fattv  dc  gene  rati  on.  'lliis  change  begins  in 
lite  auperficial  lnycn>  and  gnulually  extends  to  the  deeper  ))nrt«,  at  times 
aflecting  the  whole  thiekncM  of  the  investing  cartilage.  Oonerally  the 
changes  are  nol  ciiually  iltstribiiicd  over  the  whole 
of  the  cartilage,  not  difl'ering  in  ibis  from  other  car- 
tila^noUB  lesions  :  one  part  of  the  investing  carlilago 
may  Iw  completely  transforroed,  while  another  is 
modi6cd  only  upon  the  surface,  or  oven  does  not 
present  any  alteration. 

Tin-  fatty  degeneration  terminates  by  the  complete 
destruction  of  tlie  celU  contained  in  the  cap«ulcss, 
wherein  are  found  only  fatty  granules,  the  nucleus 
of  the  cell  having  disappeared.  At  the  same  time, 
the  fundamental  Hubstaneo  of  the  cartilage  is  soft- 
ened, and  does  not  resist  the  movements  and  prea- 
anre  of  Uie  articulation.  After  dii»  process,  the 
eapaules  containing  only  faily  granules,  are  deformed 
and  irregular  in  shape,  aa  ^own  in  fig.  VM'i. 

Frequently  these  louons  extend  into  the  second 
stage,  and  even  ^vhcn  the  cartilage  has  undergone  fatty  degeneration 
throughout  ibi  entire  thickness,  it  may  persist  without  experiencing  any 
other  modification. 

The  epiphysis  present*  the  lesions  of  the  first  stage  of  caries.  There

ing  to  the  dejjree  of  iheir  evolution  (,«cc  Caries,  p.  207.) 

The  changes  which  supervene  in  the  cartilajte  arc  not  always  the  same  ;^ 
where  the  investing  carlitage  liaa  undergone  fatty  degeneration  of  its 
cells  throughout  its  entire  thickness,  it  acts  as  a  foreign  body.     It  is 

sot^ned,  so  that,  by  the  articular  movemenia 
which  still  continue,  it  is  detached  in  large  or 
small  layers,  which  either  attached  at  the  border 
or  perfectly  free,  tloat  In  the  arliculnr  cavit^^ 
The  granulations  develojied  in  the  cpipbyseil 
may  uplift  and  also  rletiich  the  cartilage. 

Wlii-n  the  investing  oarlilugv  luis  been  onl^ 
partially  involved,  the  deeper  layen,  which 
generally  escape,  present  in  their  eleraenb*  le- 
sions which  produce  localized  thickenings,  ul- 
cerations of  Its  rilloua  surface,  new  formation"  ' 
of  fibrous  tissue,  and  oven  ccchondroses.  Al 
these  lesions  arc  due  to  proliferation  of  the 
cells  of  the  cartilage,  which  during  this  evolu- 
tion of  an  irritative  nature,  do  not  present  fatty 
granule». 

The  superficial  layer  of  cartilage  hani^

cells,  the  cajisules  of  the  deep  layer  filled 
with  secondary  capsules,  and  arranged  iu 
long  row*,  cannnt  open  upon  the  surface  of  the  joint.  At  the  »aaie 
time  that  ihi^  proliferation  is  inking  place,  the  fundamenial  sulKttance 
becomes  transparent,  and  is  segmentated  parallel  to  the  axis  of  the 
rows.  It  ia  this  process  that  causes  the  increase  in  thickness  of 
the  «iTesting  cartilage,  which  in  filuces  may  reach  seven  millimelred. 
These  hypertrophies  are  gcneruliy  limited,  and,  besides  exuberant  carti-

To  till-  nnaiilisl  eye,  upon  tlic  counoctît 
tiatuo  of  the  synovial  memhranc.  are  seen  small  whito  opaque  itjiota, 
Cfttued  by  a  depor^it  of  urate  of  soda  in  the  interior  of  the  membrane; 
although  very  superficial  in  appearance,  these  deposit»  are  very  inti- 
mately connected  to  the  Ëbroua  tissue,  and  CAnnot  be  reiooved  by

The  synovial  fringes,  li<^anicnts,  periosteum,  sheaths  of  the  tendona,

DAtnre. 

TtiU  irritation  of  t)ie  cftrtilagea  is  reco^^ited,  with  tlie  unaided  eye, 
by  a  |>cciiliar  aprwrarance  of  t)i«  deep  carlila^ioous  layer,  nol  intiltratcii 
with  urates,  ami  by  ecchondroses.  Beneath  tlie  superficial  layer,  in- 
cnistrd  with  urates.  tli«  cartilaj^  is  mure  tnit^sparent  tban  customary, 
and  presents  a  bluiiih  color,  nhcu  studied  liy  a  pcrpcndictdar  section, 
"niili  layer  rarie*  in  Hei>lli,  at  times  being;  thicker  than  the  nortiuil 
inventing  cartiliise.  a;;uin  il  may  W  scarcely  fcen.  Sometimes  the  entire 
iuvcMing  cartilage  may  be  infiltrate<l  with  unites  or  have  completely  <li*- 
apnearetl. 

By  a  nii«rowo|He  examinatioti  there  is  seen  in  the  bluiflh  layer  a 
proliferation  of  celU  with  enlargement  of  tbe  |>riiaary  caiisniea,  which 
form  tuw.t  botaeen  which  the  fundamental  ^utixtance  haa  tiecome  trans- 
narcnt  and  segmented.  The^  phenomena  of  irritation,  which  are  much 
kaa  marked  than  in  chronic  rheumadsm  or  in  scrofulous  arthritis, 
never  lead  to  villous  degcno ration,  because  the  superficial  infiltrated 
layer  becomes  inert,  and  does  not  permit  the  enlarged  capsules  to  open 
into  tlio  articular  cavity.  Therefore  there  is  at  times  a  true  accumulation 
of  new  cartila^^iitous  elements,  and  consequently  a  hypertrophy  of  the 
cartilage. 

Tb«  dimppearanoc  of  the  cartilage  is  cnuseil  by  t)ic  prof;re«<ii<rc  wear- 
ing away  of  the  surface  of  the  cartilage  inliltmtetl  with  urate.*;  there 
is  a  l'>ss  of  elai^ticily;  it  doc*  not  rv*m  tlte  action  of  friction.  'I'he 
opposed  surfaces  are  worn  away  by  the  articular  murementa.  This  may 
be  dcmonetralcd  in  preparationa  after  the  action  of  a  solution  of  potassa, 
when  wc  sec  at  the  surface  of  the  cartilage  the  round  or  elongated 
capsules  perpendicular  lo  the  surface — a  very  clear  indication  that  tho 
superficial  layer  foniied  of  flattened  capsules  has  completely  disHpp<'an.-d. 
This  wearing  away  of  the  cartilage,  however,  only  occurs  in  the  very 
movable  articulations,  while  in  those  less  movable  it  is  not  seen  even  in 
chronic  caaes  of  gout. 

When  the  cartilages  hare  disappeared  there  remnins  in  their  place 
chalky  matter,  which  *4-|ianites  the  end  of  the  Vme#,  or,  aâ  we  have 
seen  in  one  case,  there  \*  a  true  omncouh  iinkylnsis.  In  place  of  the 
articular  cavity,  the  areolie  of  !«|>i>iigy  ti.i.im-,  which  contained  urate  of 
soda,  were  seen  to  have  enlarged,  so  that  the  iiiterarlicular  line  was 
only  represented  by  a  white  mark.  .\  longitudinal  cut  of  the  bouea 
ahowed  this  singular  arrangement  very  distinctly.  The  ankrlosis  evi- 
dently resulted  from  an  osteitis  limited  to  the  extremities  of  tïie  bone«. 

These  are  not  the  only  conditions  in  which  the  medullary  ti:<»ue  of 
bones  may  be  infiltnited  with  deposits  of  urates,  They  have  been  found 
in  the  ejctremttics  of  bones,  the  investing  cartilage  of  whicii  hm  been 
presened. 

Formative  trriuiion  of  carriage  may.  in  gouty  nrtltriti»,  as  in  other 
font»  of  arthritis,  c*u»e  the  formation  of  ecelioiulrose».  generally  these 
ecchondroM-a  are  .'^mailer  than  those  in  chronic  rh(nimati.im,  and  the  peri- 
articular nodule»  in  gout  are  chielly  due  lo  chalkntoncs,  yet  they  may 
he  considered  partly  a»  ecchondm«e». 

Uouty   arthritis  is  never  «uppumtive,  but  aonielimea   very   chronic

seem  to  be  connected  witli  inSammation  :  their  cause  is  not  known. 
They  are  fnund  at  the  autopsies  of  subjects  generally  advancivl  in  age, 
and  usually  several  «re  present.  The  mtcnertcbral  disk  is  a'lherenl  to 
the  body  of  the  vertebra  in  the  same  manner  as  the  rliiirthmdial  carti- 
lages. l.'i>oii  each  o.s«cou8  siirfaw  there  is  seen  successively  a  layer  of 
calcified  cartilage,  tlicn  a  layer  of  homogeneous  or  segmcnled  hyaline 
cartilage,  which  limit:*  a  cavity  filled  with  a  mucous  utits».  The  verte- 
bral  «cchondro.iea  are  developed  from  thij  hyaline  cartilage.  Ther  ap- 
pear in  the  form  of  two  ma^we»  held  together  and  separated  by  a  layers 
of  fibro- cartilage,  which  indicates  the  inter-articular  line.  In  subjecls' 
advanced  in  age  these  eechondrose;»  are  frei|uenlly  ossified,  ai»d  the 
osteophytes  ofWn  are  separatod  into  two  parts  by  a  longitudinal  plane 
in  which  fihroniartilaginoua  tissue  atill  exists.  It  may  aUo  happen  tliat 
the  fihro-cartitaginous  layer  has  undergone  ossification,  and  then  the  two 
vertehrul  bodies  are  consolidated. 

J.  MHIler  has  pointed  oat  in  the  articulntions  ii  form  of  lipoma  whiohi

J'hysiolojfically,  the  ^ynoviid  fringes  contain  adipose  tissue  ;  the  den-

absorb  MB  does  the  bone  when  irritated  by  a  neoplasm  :  sometimes,  how. 
ever,  this  layer  yields,  and  then  the  morbid  mass  sjrows  into  the  articular

have  been  previously  described  uivlcr  chronic  arthritis  by  continuity. 

In  some  person».  and  purtîcularly  in  children,  there  is  seen  a  liw*  of

XHAXCES  OF  THE  CONXECTIVE  TISSUE  AND  SEROUS  CAVITIES. 


Sect.  I.— Ifonnal  Htttology  of  the  ConnecliTe  TUsoe  and  Seroos  Cavitieo. 

Bv  injecting  with  a  hyjxylcrmtc  Ayrinii;c  ii«ruin  of  the  blood  into  th« 
i»ibciitaiieoiid  cellular  ItitAue  of  an  adult  maainiifera,  a  portion  of  th« 
iImiic  will  t>e  diHtcndet]  m  the  form  of  a  spherical  ball  ;  the  site  of  thi.t 
mas*  .lejwiKU  upon  ihi'  .|iiaiitily  of  llie  1i>]ui<l  injected  :  onco  produc<fd,  by 
furtber  injection  it  may  be  enlarged  to  a  considerable  ai»«,  Thia  fact 
alone  domonstnites  that  there  are  not  in  the  connective  Umuo  spaiies  ana- 
logous to  those  wliich  Kichat  «IcsiRiiaWil  by  the  name  of  celle.  The  con. 
nective  tissue  consists  of  innumerable  filamvnta  of  great  flflxibilîtj.  When 
fluid  is  injected  with  »oinc  pressure  it  cnnaes  them  to  be  compraMcd,  they 
are  then  closely  applied  one  to  the  other  at  the  border  of  the  ball,  whore 
tbcy  finally  aurrouod  a  sort  of  cy«t.  Thi#  kiud  of  liinitin);  membrane  of 
the  Kpherinil  ball  ÎH  formed  of  fibres  which  «lidc  one  upon  the  other,  so 
tbat  If  we  inject  more  lliiiil  the  ey^it  U  enlarged,  but  always  has  a  spheric 
cat  form.  A  few  filament»  traverse  ihe  injected  substance  in  diHerenl 
directtoDs,  so  that  it  is  inclosed  in  meshes,  and  upon  section  tira  ma» 
presents  a  gelatinous  apfrcanince. 

A  microscopic  examination  of  the  infiltrated  portion  of  the  œdomatous 
hall,  removed  with  scissors,  shows  the  presence  of  filamentit  which  are 
fasciculi  of  councctivo  tissue  nml  elastic  fibres.  The  fttscicuH  of  eonuec* 
tive  tissue  are  lon;;itu>linally  striulerL  ;  they  seem  to  hv  formed  by  A  col- 
lection of  fibriU,  and  arc  therefore  named  raiciciili.  Thi'y  appear  w«vy 
orsiigjta»;  their  diameter  varie»  greatly,  and  caraiine  colors  them  red. 
After  the  act40n  of  carminé,  if  examined  in  water  or  glycerine  to  which 
aeetie  or  formic  acid  hits  been  added,  they  swell,  lose  their  color  and 
fibrillar  appearance.  The  swelling  is  not  eijual  at  all  points,  and  there 
are  seen  constrictions  in  the  form  of  rings  or  spirals,  which  seem  to  be 
caused  by  a  kind  of  fibre,  stained  red.  lleulo  has  named  these  fibres 
annular  or  spiral  fibres,  and  eonsiders  them  to  bo  elastic  in  nature. 

Klastic  fibres  are  found  alon:;  with  the  fasciculi,  and  are  character* 
iïed  by  their  refraction,  tbeir  perfect  cylindrical  shape,  their  anastomoses, 
and  their  rci>iHtHiice  to  the  action  of  acetic  ncid. 

Between  the  fasciculi  there  are  foutxl  two  kind.*  of  cell*  :  one,  placed 
along  the  fasciculi  of  Ihe  connective  tiMue,  are  lar;^,  Hat  like  Ihe  endo- 
thelial celU  of  the  serous  membranes,  and  contain  a  nucleus,  also  very 
flat,  in  which  one  or  more  nucleoli  are  seen.  The  other  cells  are  found 
free,  anil  have  all  the  cbaracteni  of  white  blood  corpuscles  or  lymph  celU. 
In  normal  connective  Ussue  all  the  fasciculi  touch  and  slide  ea^ly  one 
ui)un  tlie  other.

A  physiological  or  accidentai  liiibculaneous  mucous  bursa  results  from 
the  fasciculi  of  the  conneclive  ttsaue  heiiig  separated  and  pualied  aside 
at  a  certain  point,  where  tliey  are  closely  pressed  together  and  form  a  re. 
sisting  membrane.  Generally  mucous  bursK  are  traver3c<l  by  connective 
tissue  fasciculi  arranged  as  a  membrane.  The  internal  surface  of  the 
cavity  is  lined  by  an  endothelium  nhich  forms  a  complete  or  incomplete i 
covering,  the  cells  of  which  do  not  difler  from  those  found  upon  the 
fasciculi  of  the  connective  tissue;.  The  sheaths  of  the  tendons  are  analo- 
gous to  serous  cavities,  they  are  lined  hy  a  single  layer  of  flat  endotlielial 
oelis.  The  external  layer  of  connective  tisane  fibre»  hleixls  with  the  sur- 
rounding connective  tissue. 

The  large  serous  cavities  (the  pleura,  pericanliura,  peritoneum,  and 
arachnoid),  although  very  complicated  in  their  anatomiOal  stnicturo,  are 
all  of  the  same  histological  type,  and  very  simple;  a  laver  of  dense 
connective  tissue  lined  by  a  single  layer  of  flat  endothelial  celU.  The 
aixe  and  shape  of  these  cells  arc  very  variable.  The  connective  tissue 
which  constitutes  the  wall  of  serous  cavities  contains  vcrT  numerous 
lymphatic  vessels,  the  most  superficial  hi.'in;;  immediately  beneath  the 
eudolbelium  (Recklinghausen,  Ludwlg  and  Suhwciggcr  Seidel.)

Sect.  III.-(Edema. 

nistolojpeally  (cdcma  is  cssooiially  cbaractcriwd  by  an  elTusion  of  al> 
biiininous  fluid,  which  take»  place  between  the  fibrea  of  the  conocciire 
ti:(HiK'  iind  Ki-panitc't  them  from  one  another. 

When  >i;deiuatou.t  loose  eonnoctive  tisKwc  ifi  iiicisied,  instead  of  a  denw 
felt-like  li^xue,  there  is  !teen  »  gelalinou.i,  transjiarent,  trembling  maiKf,  m 
the  midst  of  which  are  found  small  collections  of  adipose  tissue,  thin  white 
marking  and  red  traheculte  which ,  correspond  to  the  vessels,  litis 
appearance  results  from  the  retention  of  fluid  between  the  Bbres  of 
the  connective  tisane,  as  water  is  retained  when  imbibed  by  a  piece  of 
cotton.  If  a  fra^nont  of  ojdomatous  connective  tissue  is  exaniined  with- 
out stretching,  the  fasciculi  of  the  connective  tissue  and  olastie  fibrca 
COntriKt,  and  uxpul  the  fluid,  and  the  tisstie  returns  to  the  normal  state. 
That  this  is  due  to  the  contrnotion  of  the  fibres,  may  bo  proven  by  placing 
the  fragment  in  fluid,  ivlicn  it  i.^  found  that  the  tissue  does  not  again  be- 
come filled  with  the  lii)nid.  Thii  property  of  the  connective  tissue  fibre» 
is  retained  for  a  long  time  notwithstanding  their  dl^ti-iislon,  and  explains 
the  easy  and  continual  discharge  of  fluid  from  |)Unoturcs  uiiule  through 
the  skin  of  dropsical  patients.  The  fluid  which  flows  from  the  ptnicturcs 
is  transparent  and  albuminous  ;  it  neither  coagulates  sjKiutaneousty,  nor 
after  the  addition  of  red  blood  corpuscles,  which  indicates  that  it  docs 
not  contain  fibrinogenic  substance,  and  therefore  it  may  be  separated 
from  intlarumatory  fluid.  There  are  always  found  in  an  edematous  fluid 
a  few  white  hloix!  cells. 

A  hislologtcul  examination  of  this  infiltrated  tissue  shows  the  fasciculi 
of  the  connective  tissue  separated  from  one  another.  In  the  spaces 
fonued  by  this  separiition,  there  is  found  a  fluid  which  contains  white 
blood  corpuscles  or  lymph  cells,  more  numerous  than  in  the  physiological

Ifonnod  of  «  single  refracting  maiis, 
rhaa  surrounding  tho  central  drop  of 
[fata  cirok-  of  ^rnnnlcs. 

In  the  caclivctic  uudi'inas  the  fat  contuinvd  in  the  cells  has  undergone 
I  partial  absorption.  This  uccurs,  for  uxunipk\iu  phthisis.  Tliere  is  also 
«onïctimes  seen  a  breaking  up  of  the  fut  of  tlic  adipose  tissue  into  deli- 
cate little  dropii.  This  change  of  the  fat  is  due  U>  the  presence  nf  an 
albuminous  fiuid  within  the  a^poite  cell,  and  is  analogous  to  an  artificial 
einuIsioD  of  fat  with  albumen.  The  nuclei  of  the  adipose  celU  are  nlnays 
very  distinct. 

Formerly  it  was  believed  that  u'deina  was  ibe  residt  of  a  stasis  of  the

Is.  lie  said  that  when  the  veins  are  obliterated,  the  blood  cannot 
pass  from  the  arteries  into  the  veins,  its  serous  ))ortion  passes  through 
the  walls  of  the  vessels,  as  through  a  Biter.  However,  Hodgson  did  not 
see  œdema  result  in  man  if  a  vein  was  ligatod.  IHic  tlicory  of  Iiower  was 
abandoned  «hen  Bouillaud  showed  that  iu  most  local  dropsies  there  is

The  obliteration  of  the  velna  ma?  ba  regarded  as  one  of  the  cauiies  of 
dmpây,  ttince  it  increases  the  blood  nreaeure  in  tbe  corredponding  capil- 
laries ;  this  obliteration  produces  oedema  in  cases  where  there  is  at  the 
same  time  an  atomic  state  of  the  vascular  system.

instrument, an  intlauiiiiiitiûii  i!t  proiliiced  which  terminates  in  recovery,  ana 
eon.ititutea  tlie  proce.i.s  neces-iary  for  the  recovery. 

An  open  wound  of  the  connective  tïs.^ue,  after  a  few  hours,  has  its  sur- 
face covered  with  a  thin  t-ravish  o|Wilescent  layer,  plastic  lymph  of  J. 
Hunter.  J.  Hunter,  his  followers,  and  the  French  surgeons,  up  to  the 
present  time,  have  mainlnined  that  this  plastic  Ivniph  is  derived  trum  the 
vessels  by  exudation,  is  susceptible  of  organisation,  and  of  the  formation 
of  the  different  tiwucs  met  with  in  cicatrices.  There  arc  found  in  this 
{jray  layer  GUincntK  of  fibrin,  white  corpuscles  or  pus  cells,  niwl  red  blood 
corpuscle».  Iteiieath  tliifi  «njmrficial  layer  the  fasciculi  of  the  connective 
ti.*i*ue  and  the  blood  ciipiiiarie»  are  separated  from  each  other  by  th« 
same  opaleMcnl  sub»>tauce,  so  a*  to  constitute  n  kind  of  membrane,  con- 
tiniiou.4  and  e.tlremely  thin.  Krom  thi*  description  it  is  seen  that  at  Ihe 
moment  when  this  so-called  lymph  becom>a  ï>olid,  it  contains  cellular 
etementa.  At  the  present  time  these  facts  might  be  explained  by  the 
white  blood  corpuscles  passing  out  of  the  vessels,  and  the  coagulation  of 
the  Ëbrinogenie  substance  (Cohnheim).  Yet  this  explanation  is  not  suf- 
ficient, for  it  is  very  p'ssihio  that  the  lymph  contained  in  the  lymphatic 
vessel*,  and  in  the  meahcs  of  the  connective  tissue,  plays  some  part  id 
these  piicnouicna.  It  bas  been  mentioned,  that  the  white  or  lymph  cor- 
puscles are  found  free  between  the  fasciculi  of  the  coiuiective  tissue. 
Again,  the  conditions  for  the  funnation  of  fibrin  are  far  from  being  per- 
fectly understood.  It  is  only  known  that  the  plasma  of  the  blood  ab- 
stracted from  the  vesseU.  coming  in  contact  with  the  panigiobnliii(KUhne). 
and  other  substances  contained  in  the  hi^ttulogical  eleincntii,  takes  the

PblegmoQ. 


CThe  name  [urulent  inflamna^on,  or  acute  phlegmon,  ts  chosen,  since 
in  rare  cases  where  the  disease  terminates  by  resolution,  there  is  never- 
ttieless  a  great  number  of  pus  cells  in  the  meshes  of  the  connective  tissue. 
The  evolution  of  acute  phlegmon  is  very  rapid  ;  redness,  increase  of  tem- 
perature, swelling,  tedema.  and  the  sharp  pain,  are  all  simullam'ously 
manifested.  The  histological  changes  occurring  in  the  connective  tissue 
during  the  first  stage,  can  seldom  he  studied  in  nmn.  Phlegmon  artifi-

Ill»  tint  «t»gia  of  [itilejcmon  is  chanci^riuid  hy  tb«  fomuttoii  of  biime- 
rous  i>uR  cells  and  a  fibrinous  extiibitlon.  'i1ic  pusoelU  increase  in  uum- 
tier  ami  tlie  (ibriu  bccomca  more  abundant  ;  titi»  material  cxtnmU  between 
tiic  tibrea  and  consolidates  Ihein;  the  infla minatory  tumor  becomes  firm, 
fpviiijj;  a  sensation  of  resistance  to  the  fingers.  There  is  no  fluid  nreseut 
which  may  be  displaced  aa  in  œdeina,  and  it  is  to  the  presence  of  fibrin 
filling  the  iMfthe«  of  the  oonnoctive  tissue  that  the  limiting  of  the  phleg> 
mon  should  be  attributo<l.  in  cuta  where  the  course  bas  been  slow. 

In  man,  this  first  stage  is  f'lUowcd  cither  by  rr»olution,  tntiuratt'on,  or 
tufipuniiiuM.  When  resolution  is  produced,  it  is  probable  that  the  cs- 
caprd  white  corpisclea  are  take»  up  by  the  lymphalica,  citlivr  in  their 
nonnal  state  or  afWr  havinj;  tuidcr^rouc  »  molecular  séparation,  and  that 
the  fibrin  and  exlrarnsated  rod  blood  cells  experience  the  saoie  change. 

ln<luration  without  suppuration  has  a  v«ry  cIo»e  analogy-  to  tlie  indur- 
ation which  succeeds  the  opening  of  an  almccs*  ;  the  histological  clutnges 
are  |>n>l>ably  the  same  in  both  case:».  There  U  a  proiluotion  l>etw(-cn  the 
fasciculi  of  the  connective  (in^ue  of  new  cellular  elements,  while  around 
lli«m  there  exists  a  new  fundamental  substance,  transparent  and  of  »ott 
consistence.  Later,  the  cellular  elements  present  a  fatty  degeneration, 
and  the  new  tissue  is  absorbed. 

Id  eirery  phlegmon  pus  ccIU  arc  formed  in  the  meshes  of  the  con* 
nectivo  tisstK.  When  their  production  19  very  olnindant,  the  conncclire 
tissue  fasciculi  urv  wparated  or  undergo  inflammatory  softening  and  nb- 
aorption,  tiius  forming  a  pnruletit  collection  or  »u  aW«s«.  The  phleg- 
mon is  now  said  to  have  Kuppiirat«d. 

The  pus  of  a  circumscribed  ])lilegmon  is  creamy,  homogeneous,  and 
does  not  contain  fasciculi  of  connective  tissue.  Examined  with  the  micro- 
acope,  the  purulent  Quid  presents:  1st.  round  cells  exactly  resembling 
whit«  blood  corpuscles  containing  only  one  nucleus  ;  2d,  colls  of  the  same 
diameter  possessing  several  small  nuclei  :  :îd.  similar  cells  with  fally  gran- 
nies varying  in  amount;  4th,  large  cells  inclosing  fat  granules,  the  granu- 
lar corpuscles  of  Glugo  :  5th,  red  blood  corpuscles  perfect  or  broken. 

The  sac  which  incloses  tliv  pu«  is  anfractuous  and  lined  by  a  layer 
similar  to  that  which  is  formed  the  Mcond  day  upon  the  surface  of  a 
wound-  Hero  the  fasciculi  of  the  »oftcnitd  connective  tissue  are  united 
together  hy  a  layer  of  coagulated  fibrin,  in  which  are  seen  pus  cells. 

When  the  abscess  is  ojieiiod  by  the  surgeon,  the  pus  escapes,  the  wall» 
of  tlic  empty  sac  coming  together  are  united,  and  there  resulL^  an  indu- 
ration which  persists  for  a  fen  days,  (ieuerally,  the  bottom  and  mlvi 
of  tiie  absces*  granulate  and  form  pus,  when  the  phenomena  are  those  of 
a  simple  wouikI. 

In  diflused  phlegmon,  the  inflammatory  changea  are  so  intense  that  the 
layers  of  connective  tissue  have  not  lime  to  undergo  inflammatory  absorp- 
tion. They  die  and  act  upon  the  neighboring  parts  as  foreign  bodies. 
Properly  speaking,  a  diffused  phlegmon  is  a  true  necrosis  of  the  con- 
nective tissue,  and  is  very  similar  to  a  suppurative  ostco- myelitis. 

When  the  purulent  centres  are  opened,  there  are  found  mingled  with  the

for  study  a  fibrillar  idilss.  in  which  it  is  difficult  to  distinctly  recognise

Sect.  TI.— Chronic  Phlegmon.

The  name  chronic  phlegmon  is  git'en  to  intlammalions  of  the  con- 
nective ti^due  of  long  duration,  charafiterized  by  a  lardaoemia  induration 
iU'>ual1y  accompanied  by  suppuration.  It  is  not  a  primary  disease  of  ihe 
connective  tissue  ;  it  accompanies  chronic  affections  of  tlic  bone  or  of  the 
vascular  system. 

Soinelimes  the  thîcltcnîng  of  (he  connective  timuc  i*  Considerable  jiimI 
8imulHt«-s  a  tumor  ;  but  the  tnuiefaction  i.*  never  clearly  circumscribt-d, 
it  blends  with  the  nei^Iibonng  healthy  parM,  so  that  it  is  difficult  to 
■s«ign  any  definite  limits  lo  the  lesion.  t"[ion  die  iturface  of  the  ^kiii 
th>Te  may  be  seen  either  ulcers,  tistular  openings,  or  pa]>illary  hypcr- 
tropliifS. 

Upon  making  an  incision  into  the  morbid  mass,  the  tissue  presents  a 
tardaceotis  appearance,  and  a  serous  or  opaque  fluid  flows  from  it.  Care, 
fully  examining  the  surface  of  the  section,  distinct  fibrous  portions  are 
recognized,  which  correspond  to  the  tendons  or  apoucuroses;  parts  trans- 
lucent and  inliltrutcd  nith  fluid,  as  iniclcni»:  irregular,  opa<|ue,  aud 
purulent  spot»)  ;  dilated  congested  vessels,  and  lieinorrhagic  poinbi. 

In  order  lo  study  with  the  micrOKcope  thi*  complex  lissuo,  it  is  neces- 
sary to  employ  sevurui  inetlioila.  The  elements  obtained  by  leasing  • 
tresh  jncce  are  pus  cells,  gruntilnr  corpuscles,  and  cvlU  larger  tlian 
those  of  pu«,  of  varied  .«hape,  rovitul,  ftiâîfnrm,  flat,  irreicular,  similar  lo 
those  seen  in  a  sarcoma.  IWiden  tliese  cellular  elements,  there  arc  weft' 
fat  granules,  drops  of  fat,  and  fibres  of  connective  tissue. 

In  thin  sections  after  hardening;  the  tissues,  tliere  are  found  fas- 
ciculi «f  connective  tissue  running  in  difl'erent  directions  and  separated 
by  collections  of  cells.  Some  resembling  white  blood  corpuscles,  others 
larger  aud  fusiform,  representing  the  fixed  cells  of  the  cmncctive  tissue. 
In  theae  sections  the  bloodvessels  present  embryonic  walls,  and  are  sur. 
rounfled  by  an  irregidiir  moss  of  pus  cells.  At  times  small  spots  of  atro- 
phied adipose  cells,  with  a  multiplication  of  their  nuclei,  arc  found  ;  tbey

Sect.  Vn.— Tumon  of  the  Connective  TiMue. 

All  tumors  without  any  exception  may  be  developed  in  the  connective 
tissue,  but  it  does  not  follow  thai  the  cells  of  ibe  connective  tissue  are 
the  only  source  of  these  neoplasms,  as  Virchow  has  maintained.  It 
lias  been  previously  shown  that  almost  all  the  ncoplasma  constituting 
tumori,  at  their  beginning  comisi  of  an  embryonic  masa,  which  is  the 
origin  of  the  new  tissue.  The  method  of  formnlion  of  cmbryonk  tiiwue 
from  connective  tissue  is  the  same  in  a  simple  intlnminatton  am)  in  the 
V'^inniiig  of  a  tumor.  The  cells  which  form  it  are  probably  the  while 
blood  corpuscle»  escaped  from  the  vessels,  and  the  cells  of  the  connective 
tiMue  multiplied  by  divi«ion. 

The  most  fréquent  tiimon  of  the  loose  connective  tissue  are  those  which 
have  their  analognes  in  the  varieties  of  this  ti^tue. 

The  epitheliomala  which  are  developed  in  the  connective  tissue  always 
have  their  oi-ij;in  in  the  inter-pajiillary  epithelium,  or  in  ibc  embryonic 
tissue  in  contact  with  pre-exiitting  epithelial  masses.  All  other  tumors, 
the  osieomata,  chondromaia,  etc.,  may  also  bave  tbeir  origin  in  the  loose 
connective  tissue. 

ycrous  cysts  of  the  connective  tissue  are  always  lined  with  endothelial 
cells  similar  to  thosv  of  the  serous  membranes,  and  of  the  eouneocivc 
tissue.  Their  waill  is  formed  by  the  fibres  of  the  connective  tissue  placed

seen  succesaivo  layers  of  cells  previously  described,  and  fibrin  arranged 
differently  according  to  the  case.  Usually  the  fibrin  forms  a  network, 
the  flattened  meshes  of  which  limit  elongated  alveoli  containing  the  cells. 

The  limit  of  the  serons  membrane  is  always  very  distinct,  the  exuda-

cells  ;  they  become  caseous,  shred»  arc  detached  from  their  surfaces  and 
float  in  the  serous  cavity.     The  shred»  and  exudations,  yet  adherent,  are  . 
composed  of  a  granular  substance  produced  by  the  molecular  se}>aralioD^

A  thickening  of  the  pleura  is  especially  seen  around  oiasses  of  caseous

tlie  feeaela  Gorres)K>nding  to  the  tubercles  present  the  modifications  which 
hare  been  explained  at  pa^  116, 

The  ilcrelopmcnt  of  tubcrcidous  gmnutatioiia  upon  th«  surface  of 
serous  membranes,  at  the  bej^inninj;  of  their  evolution,  is  not  always

tho  granulation  come  from  tho  endolholium  of  the  serous  membrane,  from 
the  while  blood  corpuscles,  or  from  both  of  these  sources?  At  present 
it  IS  impossible  to  decide.  Yet  IlindHcisc-h  maintaiiK^d,  nt  a  tîtue  when 
the  emigration  of  t^e  white  blood  eorpui^les  was  unknown,  and  also  very 
recently,  that  the  proliferateil  endothelial  cells  wore  the  |wint  of  origin 
of  tubercle.  It  is  very  probable  that  these  cell*  take  part  in  tiie  forma- 
tion of  superficial  granulations,  but  it  ha*  not  been  demon:strated  tliat 
they  «loite  arc  the  origin  of  them.  ^Vheu  tlic  tuberculous  i^anula^ons 
are  developed  in  the  ileptli  of  the  connective  tissue  of  serous  membranes, 
or  in  the  granulall>)ii  tissue,  they  spring  fi-om  embryonic  tissue,  which 
may  be  derived  either  from  the  jiroliferated  flat  cells  of  the  connective 
tiisue  or  from  whit**  blooil  corpusctea. 

Primary  ritreinoma  of  serous  membranos  is  very  rare,  but  secondary 
carcinoma,  by  extension  or  generalixaiion,  is  very  ircnucnt.  Of  all  the 
primary  caremomata  which  bave  been  obwn-ed,  the  most  common  is  col- 
loid carcinonia  of  the  periton*'um.  either  u|)on  tlie  peritoneal  surface  of

''Wrous  connective  tissue.  In  the  great  omentum  tlie  reticulum  is  trans- 
formed into  a  flat  ma^,  having  none  of  the  structure  of  the  omentum,  but 
only  that  of  collotil  carcinoma. 

The  other  varieties  of  caivinomata  have  their  origin  in  tbc  organs  cov- 
ered  by  serous  membranes;  whileincreasin;;  they  form  round  mn.^O»  which 
cause  inilammation  in  the  serous  membranes,  tbc  exudation  of  which  is 
almost  always  hemorrhagic.

Between  the  secondary  faticicuii  arc  placed  tlie  arteries  and  veins. 
The  iiipilliirics  pooelraw  ilic  aci-ondary  fasciculi  and  arc  dtaipilm«d  be-

envelop  in  ihcir  network  the  primary  fasciculi.  These  capillaries  are  ab 
way»«ituateil  extenial  to  the  «nrcolenimu.  The  entire  muscle  is  cnaheathed 
by  an  «poncurojibt  formed  of  cWc  connectJve-tiiMue  laniellic,  which  can  be 
separated,  as  iihown  by  inji-cliuf^  a  lluid  into  th<-  muiiclc  beneath  the 
a[ioneuro.^is ;  the  fluid  will  pass  through  the  aponeuroiti;»  to  the  cxtvnial 
surface  of  the  muscle.  A  fluid  may,  therefore,  penetrate  tliroiigliout  the 
whole  ext4.>nt  of  a  muscle  between  the  primary  fasciculi,  tiic  conneottvc- 
tissue  fibres  and  vessels.  Consequently,  a  rauscle  possesMS  a  vast  inter- 
stitial laciumr  system  belonging  to  the  connective  tissue,  and  which  i^  in 
counminieution  witli  the  lymphatic  system.  All  muscles  have  tendons  of 
insertion,  h  was  believed  for  a  long  time  that  the  primary  fasciculi  of 
the  muscle  wore  directly  continuous  with  the  fibre*  of  the  tendon. 
Kulliker,  howcTur,  hai  «ecu  that  when  the  muscular  fasciculi  came 
obliijuely  upon  a  tendinous  surface  they  were  not  continuous  with  the 
tendinous  fibres:  but  he  per8i!il«d  in  believing  that  in  vases  where  the 
tendinous  fibres  have  the  same  direction  as  the  muscular  fasciculi  they 
were  continuous.  Weiîmann,  in  studying  the  muscular  insertions  by 
chemical  melhoda,  found  that  a  solution  of  pota!<h  demon^traled  the  union 
of  the  muscular  fasciculi  with  tiie  tendon  by  means  of  an  organic  cement 
or  uniting  substance,  wiiicb  under  the  actinn  of  this  reagent  is  softened

fantile paralysU,  or  only  a  fen- are  attacked  hy  tlic  atrophy,  as  occurs  toi 
low  fehrilc  diaoases.  It  is  not  certain  that  in  the  phyaiolo^cal  8tat«  th« 
mmicular  fascicalî  of  man  are  not  renewed,  since  in  the  adult  very  con- 
siderable difTercnccii  in  the  diameter  of  the  fasciculi  of  a  muscle  exist. 
Some  are  scarcely  the  ouc-hundrcdlh  of  a  millimetre,  while  others nieasnro 
tlirep,  seven  huiiilredths  nf  a  milliini'tre,  and  even  more.  In  lliu  aged, 
this  rliffi-rence  is  mori;  marked,  and  there  are  constantly  found  in  their 
mu^^clcs  fasciculi  containing  fatty  granules,  and  other*  also  undergoing 
•trophy. 

The  atrophy  is  simple,  or  is  caused  by  some  of  the  nutritive  changes 
irhich  will  be  later  studied.  Usually  these  changes  at  the  hoL^innhig 
occasion  an  increase  in  the  stie  of  the  fasciculi,  the  atrophy  occurring 
Bub3e<|uemly.  The  airopliied  muscular  fasciculi  are  very  variable  in 
Bixe  and  shape.  Any  fasciculus  in  the  aduit  not  exceeding  the  four- 
hundredth  of  a  millimetre  may  be  considered  atrophied.  When  the  fa»i- 
ciculi  have  an  average  diameter  of  one-hundredth  of  a  niillimetre,  th6j 
atrophy  is  consiiierable.  Finally,  the  sarcous  substance  may  have  «ob 
plctely  diïnppi-arpd,  at  least  in  some  of  the  fasciculi  ;  the  latter  are  rep. 
resented  only  hy  recliHnenr  filaments  fonnwl  by  the  sarcolemma,  empiy 
and  shrunken.  In  an  extensive  and  uniform  atrophy  of  muscles  the 
Rtriatiun  of  the  muscular  suh:^tance  may  be  manifestly  preserved  in  fas- 
oicidi  measuring  only  the  three-thousandth  of  a  millimetre.  These  fas- 
ciculi possess  nuclei,  and  opposite  each  of  the  latter  the  fibre  prcseuts  a 
slight  swelling.  This  variety  maybe  seen  in  progressive  muscular  atrophy^  1 
in  infantile  muscular  paralysis  during  its  second  stage,  and  in  all  atrophies 
which  depend  upon  the  nervous  system. 

In  some  case»  of  ulnb-foot  and  infantile  paralysis,  the  connective  tissne 
at  times  has  so  increased  that  it  more  than  compensates  for  the  atroptij. 
of  the  muscular  fasciculi,  so  tliat  the  muscle  truly  atrophied,  in  it«  esse»' 
liai  elements,  is  considerably  larger  than   in  the  normal  «tUe.     Tliis^

In  eaav«  where  the  hyporlrnphy  of  a  inuaale  is  owing  to  tlie  formation 
of  new  muscular  elemem,-».  llie  phenomena  of  new  formation  can  he  very 
well  Men.  It  wni^  in  such  canes  tii.at  Hardeleben  studied  the  origin  of 
new  mm«ular  fasciculi  from  cells  of  the  connective  tissue,  in  a  hyper- 
trophy of  the  inicrcoslal  muscica  occasioned  by  a  prolonged  dyspooca. 
A  new  fonnation  of  muscular  fn^ciculi  constantly  occur»  in  adults  suffer- 
ing with  an  acute  tiisoasc  ;  boidc  of  the  fasciculi  arc  destroyed  by  nu- 
tritive chiinj;c5.  The  physiolopcal  restoration  of  inusclf:».  «iVr  febrilfi 
emaciation,  is  due,  not  only  to  an  inerea«e  in  aixe  of  tlie  shrunken,  yet 
unaltered  fascicult,  but  also  to  a  fonnation  of  new  muscular  fasciculi 
which  are  develo(ied  between  the  old.  The.se  phenomena  have  been 
Studied  by  Zenker  in  several  febrile  dbeaaes  (typhoid  fever,  scarlatina, 
etc.).     (See  U.  fig.  l.'il.) 

The  same  vear  Colhcrs  demonstrated  an  analogous  regeneration  of 
muscle  followmg  trichinosis.  It  is  always  from  the  cells  situnldl  outi-îde 
of  tlio  fasciculi,  that  nre  ilcvclopcd  the  no». formed  muscular  fibres.  The 
nuclei  of  these  cells  are  multiplied,  their  protaplasm  is  increase<l,  forming 
blunt  or  tapering  prolongations;  this  nucleated  mass  is  vert'  similar  to 
the  large  giant  cells  of  bone  marrow.  Neighboring  cells  unite  at  their 
extremities:  thv  substance  which  forms  them  is  transversely  striated, 
ftnd  takes  all  the  charact>;rs  of  striated  muscular  ■«uiisiance. 

Increase  in  the  size  of  a  mtisciv  is  not  always  due*  to  an  increase  in 
aiise  of  the  fa.sciculî.  or  to  their  new  formatiiMi  ;  it  may  result  from  tli« 
production  of  connective  liasue,  of  adipomo  tiitsue,or  even  to  an  abnornui] 
developinent  of  blood  or  lymphatic  capillaries.  Hypertrophic  paralysis 
of  muscles  has  been  previously  mentioned  ;  congenital  hypertrophy  of 
the  tongue  is  princijally  due  to  a  considerable  thickening  of  tl>c  wn- 
nectivv  tissue  of  the  organ  anti  a  dilation  of  the  lymphatics.

coinbinatiou  ;  it,  therefore,  interferes  with  the  function  of  this  tissue. 

Muscular  fasciculi,  which  have  undergone  a  fatty  degeneration,  are 
mo^^  friable  than  normal,  and  retjuiro  more  care  in  preparing  them  for 
microscopic  examination.  Tho  fatly  sraimlcs  of  the  degenerated  muscular

de;:cncralii>u  be;;ins  in  the  protoplasm  immediati'lv  around  the  nncbi. 
It  is  very  probable  that  tho  fascicnii  which  have  undergone  fatty  de;;e«. 
eratiou  may  again  pctuni  to  thi-ir  physiological  slato,  if  our  conclu> 
aions  are  based  upon  vhat  occurs  in  frogs,  in  whom  during  winter  a  great 
manv  of  tlic  fasciculi  are  fntty,  which  in  summer  return  to  their  normal 
eoDoitioD.  In  man,  honcver,  freipiently  the  fasciculi  which  have  expe- 
rienced thi»  change  are  destmyed  by  a  process  the  different  phases  of 
which  cannot  be  well  folhiwcd.  The  fatty  ^rniinle:»  become  more  and  more 
abundant,  the  fasciculus  bt-comeR  opa<[ue,  the  slrialiuu  cannot  be  distin* 

»gnished,  an*!  al  the  ctkI  of  the  process  the  sarcolcmma  sheath  is  filled  by  a 
fatty  ;^ramilar  ma.->s  which  gr.iilually  disappears,  leaving  only  the  shrunken 
aareolorama.  It  is  chiefly  in  tumors  of  miiacles,  am!  in  callus  when  it 
invadea  the  muscular  substance,  that  these  madiËcalions  may  be  inicsti- 
gated  in  detail  in  the  human  being. 

In  infantile  paralysis  and  progressive  muscular  atrophy,  tho  mnscutar 
fasciculi  may  nt  part  or  comjilctely  disappear  from  the  effect  of  fatty 
lie  gene  ratioti.  Fatly  degeneration  is  also  met  with  in  fevers,  in  puru-

bave  undergone  any  cbanj^e.  The  nuclei  of  tiic  fibres  and  the  proto- 
plasm which  siirrniiiids  them  entirely  escape  the  vitreous  change;  they 
appear  upon  the  hoino(;eneous  fasciculus  as  a  ili^tinet  granular  mass. 
Carmine  color»  the  vitreous  substance  quit»;  inumsely.  Acetic  acid

the  vitreous  muscular  substance  retains  its  cylindrical  form. 

The  number  of  fasciculi  afTcctcd  by  the  defeneration  is  always  limited. 
All  the  muscular  fasciculi  of  a  mu»ele  are  never  found  metamorphosed  : 
therefore  an  examination  should  include  a  «^oup  of  fasciculi,  rather  than 
an  isolated  primary  fasciculus.  There  are  seen  bnmo^eneous  and  tran- 
sparent fasciculi  presenting;  at  tbeir  cd^-s  n  charucteristic  npjicarancc

generated. By  the  side  of  the  vitreous  mu.teular  fibres,  which  have  lost 
their  physii>loj;i«al  properties,  there  are  found  others  intact  and  able  to 
contract. 

The  changes  which  we  shall  now  discuss  are  moat  marked  in  chronic

eonfle<jucnco  of  rapture  will  be  better  iitmlt«d  under  lieinorrhagea  of 
ntuiiole. 

The  aiu»e  of  this  degeneration  is  local  or  general.    In  the  former  ease 

it  is  localised  at  the  scat  of  the  aflectioi)  which  occasions  it,  ah  a  tumor 

[of  a  muacle,  an  abscess,  or  a  chronic   phlegmon.     When   the  disease

'muscles  of  the  thi[;)i  and  abilomen  :  yet  it  may  oceur  in  any  locality. 

To  the  unaided  eyo.  it  i»  vcrr  difficult  or  even  impossible  to  rccoj^M 

this  lesion.    Zenker  ha»  pointed  out  a  special  color  analogous  to  fish  flesh  : 

but  this  color  may  be  seen  in  muscles  which  do  not  prcsonl  the  tlc;^-ncnii- 

tioD,  no  ihut  a  bistolo^ical  examination  is  necessary  to  detenuine  it. 

ItRM>muiiA<iK^  iir  MfSi7LKK. — Simple  oonjçeîition  of  a  miiwle  is  mani- 
fciteil  by  ili!>tinct  .li^nii  upon  tl)e  cadaver  only  in  the  nci^iborhood  of 
inliammatory  foei,  of  hemorrhages  and  of  infarcti. 

By  the  old  I-'ronch  and  (îcrmans  authors,  hemorrhages  of  nmscle^  were 
designated  hemorrhagic  infarct!.  This  term  by  no  means  implies  the 
idea  of  a  primary  arterial  obliteration. 

Hemorrliages  in  tliu  muscles  rimy  be  eaused  by  contusions,  wounds,  rup. 
turu  of  muscles,  or  they  nmy  depiiid  iipon  a  grneral  hrmorrhagic  affec- 
tion, jiiicli  as  purpura,  «curvy,  liomorrha};ic  fever»,  Icuencythicinin,  etc. 

If  till'  heinorrba;;e  is  recent,  it  foi-m»  in  the  mnsele  a  dark-red  mass, 
very  difTeront  from  the  light-red  color  of  the  miwelc.  This  mass,  the 
extent  and  «liape  of  wliich  is  very  variable,  may  lie  limited  or  diR'ui^ed. 
Ak  the  blood  coagulates,  the  muHcle  at  thi.4  poîiu  become»  more  con.^iiitent 
and  lo«es  its  elasticity.  Tlie  naiLicular  fasciculi  contained  in  the  part 
liave  not  undergone  any  alterations,  or  [lerliaps  they  iiave  become  granular. 

In  order  to  study  the  relative  relations  of  the  bloo>l  and  the  muscle 
fibres  and  vessels,  thin  transverse  sections  are  to  be  made  anil  colored 
with  carmine.  It  is  then  seen  that  the  muscular  fasciculi  are  separated 
by  coHections  of  red  blood  disks.  In  these  collections  and  between  the 
fasciculi  the  blood  ciipillHries  and  vessels  of  larger  calibre  arc  dilated 
anil  filled  with  red  blood  disks.  Thv  bli>ud  coagulatvs  in  the  vessels,  as 
well  as  in  the  interfascicular  spaces,  in  eonscijnencc  of  arrest  of  the  cir- 
culation. 

When  hemorrhage  follows  a  rupture  of  a  miincle,  the  blood  ooagidates: 
the  torn  fiMciculI  of  tlie  mnscbt  project  into  ihi.-t  coagulum,  aiitl  the

Xh«  blood  thus  efl'uacd  into  the  muscle  seems  Co  be  absorbed  with  great 
facility.  The  muscular  morouifints  certain!;  have  considerabl«  influence 
u|>on  the  inlra-muscular  lymphatic  circulation,  and,  con!M)i|uently,  upon 
Uie  transporuiiou  of  tnau-rinls  whioh  arc  derived  from  the  changes  oc<

however,  that  the  elTeet  of  severe  contiiuonA,  irhich  are  alwaya  aocom- 
paniod  witli  coiniclcrahte  intra-mnscular  hemorrhage»,  may  disappear  in 
a  few  days  witJioul  leaviu);  any  trace.  The  changea  ocourrinï  in  the  blood 
do  «ot  differ  from  tho«e  deHcribed  tinder  hemorrhages  of  the  connective

changes,  it  becomes  soluble,  or  broken  up  into  very  tine  granules  which 
are  taken  up  by  the  circulation. 

The  production  of  muscular  hemorrbagea  raries  according  to  their 
eauoe.  When  they  are  the  resutt  of  direct  injury,  such  as  muscular 
rupture,  fracture  of  bones,  contusions,  the  torn  vessels  permit  the  blood 
t<)  esca)K:  until  by  its  coajpilation  it  occludes  the  ruptured  vessels. 
Hcmorrha^fli  rnny  also  be  due  to  oblitcratidn  and  thromboaia  of  the 
veins,  when  the  arti.iml  pressure  tranituiitted  to  t)io  oapillaric»  i»  suf- 
ficient to  cause  their  rupture.  But  the  «hliteratiou  of  arteries,  either 
l)y  thrrmibftTtis  orcmbolium,  cantint  cause  intra-muscular  hemorrhage,  any 
more  tlian  cau  lij^tion  of  iin  artery. 

The  phcnomeiui  of  nancular  hemorrhageii  in  general  dtseaaea,  such  ai 
purpura  and  the  hemorrhagic  fevera,  are  not  yet  known. 

Embolic  Iscirctiox  dp  Mr«cLES. — Tme  embolic  infarcli  of  muscles 
thave  been  seldom  aeen.     We  understand  fay  this  term  the  alteradon  con- 
I  lecuiivc  to  the  obliteration  of  a  muscular  arteriole  and  its  branches. 
■  Thia  lesion  differs  from  hemorrhagic  infarctt  by  the  absence  of  offiised 
blood.     Metastatic  abscesses,  such  as  have  been  described  under  inllam- 
inationa.  shoulil  not  be  conlo\iiidcd  with  embolic  infarcti  of  muscles.     We 
have  only  met  with  two  examples  of  this  legion,  occurring  in  consequence 
of  emboli  from  endocarditis  and  endarteritis.    In  these  ca^^,  in  the  mus- 
cular substance,  were  found  whitish,  slightly  opaiitic,  eonc-sliapcl  massos, 
which  were  in  very  distinct  contrast  to  the  red  and  translucent  muscle, 
Micmscopic  cxuminiition  of  these  parts  showed  that  th(^  muscular  fa», 
cicnii  had  very  plainly  preserved  their  str'iation  ;  they  cout-iined  no  fatty 
|f:ranult's,  but  tnclotted  only  n  few  pi<;iDent  )^ranule-«  derived  frnin  the 
f  muscular  haemoglobin.    This  pigmentary  chantée  is  similar  to  tliat  occur-

Sect.  I.  -  Koimal  Histology  of  the  Blood. 

Th«  morphological  ekmenta  of  the  liloni)  in  the  normal  atate  are  red 
and  «hile  corpusclca:  there  are  abo  found  eleineiitarT  ^ranulea  which 
Boat  in  the  senim,  and  «hen  the  blood  coagulates,  a  reticulum  of  fibrin. 
Crvstalfl  arc  formed  either  sponuneougly  or  arti6cially. 

Il'he  red  corpuaclcs  of  man  arc  disks  slightly  depressed  in  Ibetr  centre 
upon  both  surfaces:  whvn  seen  in  profile,  thoy  have  the  form  of  a  bi* 
concave  lens  ;  mccn  upon  the  surface,  their  centre  is  dark  and  the  honler 
bright,  atJO'irdin;;  to  the  pnsilioii  of  the  objective.  \Vh«n  the  ohjwtîvo 
is  nearer  tlinn  llit:  point  of  distinct  virion,  the  centre  i:<  dark;  when  it  i« 
beyond  the  jK)iiit  of  ilinlinct  viMon,  it  h  bright.  The^  detaiU  arc  {pvca 
that  the  depressed  centre  may  not  be  taken  for  a  nucleus. 

The  higher  the  inHgiiifying  power  employed  in  examining  red  cor- 
puscles, the  less  they  ajtpear  to  W  colored.  Vhua.  with  a  power  of  800 
diameters,  they  have  only  a  very  sHj^ht  yellow  tint  ;  in  profile,  they  aroi 
more  colored  th:in  when  seen  u|ion  the  xtirfucc.  The  red  corpuscles  ar« 
not  of  uniform  diameter,  yet  they  rary  very  little;  their  avcra;;c  diam> 
vter  is  .OUT  mm.  Besides  the'  dÎ!çk-«hape<l  corpuscles,  there  are  often 
found  sphvricnl  red  eorpusck-s  hurin;^  only  .00;>  mm.  ;  thcîr  tînt  is  tlarkcr, 
which  is  due  simply  to  their  shape.

very  minnif  spherical  ;;ranule.-t,  vthnnte  eonaiitution  ap]>ears  to  K>  idenlioul 
with  that  of  the  Ittrj^er  red  eorpuAcles.  The  aise  of  these  small  spherical 
bodies  varies  between  a  minute  dot  scarcely  visible  under  a  magnifying 
power  of  :{Ml)  diameters,  and  .(R'.'i  ram.  Some  authors  believe  lliai  they 
come  from  the  broakin;;  up  and  division  of  the  red  blood  disks  in  the. 
spleen  :  that  diirin;;  the  passage  i>f  the  splenic  blood  through  the  liver  k  ' 
]"nrt  of  the  proper  tunclion  of  thi-  hitler  is  to  complete  their  destruction  ; 
and  that  their  presence  in  considerable  numbers  in  the  genera]  circulstioD 
is  an  iriilicHtion  either  of  a  dÎMease  of  the  spleen  or  of  the  Urcr,  or  por>

The  cohriii;;  maicrial  of  the  blood  dissolved  in  the  serum  is  named 
hiemo;;lobin ;  it  is  soluble  in  larjjc  (luantitic*  of  water  without  being

iK'Hiorrha^^-»,  notably  thotte  of  the  brain,  that  tlie  noM  beautiful  i«pcci> 
nivM  of  these  crystals  are  met  vitb. 

The  whiu  eûrputrlft  are  seen  as  «pberical  hodies  or  have  an  irregular 
contour;  tbi^y  are  simniilar,  aiul  nnder  the  microwope  have  a  ^ray  tint. 

Prolongations  of  vnriixi»  KhapCH  are  somelimeit  seen  at  tboir  borders. 
Ill  the  froj^  and  other  cold  hloodod  amniaU,  these  prolonjaiions  are  ri-ry 
dintinclal  the  moment  the  blondis  drawn  from  the  vessels  and  suliiiiitted 
to  examination,  but  become  more  and  more  prominent  aa  the  obsvn'alion 
is  continued  ;  they  change  their  ahape,  form  secondary  prolonKaliona,  and 
again  return  to  their  ori;^nal  form,  thus  presenting  the  anxuboid  move- 
nenta.  The  white  corpuscles  possess  the  projierty  of  scinin;;  the  bodies 
which  arc  near  them  and  causing  ihcni  to  penetrate  into  tlieir  inlerinr 
{Itcclilingliausen).  This  phenomenon  can  be  directly  ohservcd  under  the 
iniomscope  by  mixing  with  a  drop  of  froa's  blood  a  «mail  amount  of  gran- 
ular cuniiinc  or  vermilion.  The  absorption  of  solid  particles  may  aliw  he 
studied  in  the  organi«m  by  injecting  into  the  vancular  system  of  a  frog 
or  a  wnnnbliindcd  animal  fine  (mrticlcs  sunpendedin  a  fluid,  and  examin- 
ing the  blood  of  the  anituaU  a  few  minuter  nfter  the  injection.  The  white 
corpiusclea  are  then  âeen  to  have  in  their  interior  grains  of  the  injected  snlj- 
suncc.  The  rc<l  corpuscles  never  contain  any  of  the  injected  particles. 
The  power  that  the  white  corpuscles  have  of  absorbing  solid  particles 
when  removed  from  the  organism,  shows  that  they  still  live,  altliough  the 
conditions  of  their  existence  seem  changed.  These  vital  manifesta tionn 
may  be  prolongcil  for  a  lung  time  if  the  blood  is  protected  in  a  suitable 
incliuni. 

[IVxidcs  the  ahove-mentinnod  while  corpuscles  found  in  the  blood,  tbere 
are  occasionally  seen  other  oolorivsa  olemenl.-'.  There  arc  a  certain 
numlierof  larger,  more  granular,  and  Ics»  mobile  colorless!  cells,  met  with. 
In  the  frog,  especially  during  the  spring,  a  few  lari^  ellipsoid,  slightly 
granular  uni-  or  bi-nuc1oated  colorie?»  cells  are  found.  Klements  very 
similar  to  the  latter  are  found  in  the  Hood  of  the  splenic  veins  of  mam- 
mats  in  health,  and  in  the  general  circulation  in  some  pathological  states.] 

The  whiu^'  corpuscles  arc  much  loss  numerous  than  the  red.  In  a 
healthy  man  there  is  one  white  to  three  or  four  hundred  red.  'ITie 
numeration  is  <liflieult  :  therefore,  to  cstimnlc  the  physiological  aa  well 
as  the  pathological  proportion,  it  is  well  to  have  some  rajwd  method. 
By  the  action  of  water  the  white  eorpusoloa  become  spherical,  trans- 
parent, and  in  their  interior  apjwar  one  or  more  nuclei.  If  the  action 
of  water  is  prolonged  the  cell  i*  ili**olvei|,  the  nuclei  only  remaining.

The  alterations  of  the  blood  in  disease  arc  numermu;  they  are  almost 
all  recognixed  by  chcniiail  analysis,  but  a  few  arc  distinguished  by  the 
microscope:  the  latter  only  will  be  here  coufttilered.  They  consist  in 
variations  in  the  number  of  the  e<>r|>nsclË»,  in  the  jireseiioe  of  bodies 
which  do  not  exist  in  the  blood  in  the  normal  state,  aiul  finally  iu  ihe

He  rccognixes  a  loucocytlucmia  connected  with  hypertrophy  of  the  spleenj 

and  another  with  the  lymphatic  glands.     This  distinction  cannot  ho  nuunJ 

tftined.forif  till'  blood  of  :i  leuonoythicmic  patient  is  examined  sereral  dajM 

in  succession,  it  i«  found  tliAt  smiietiniex  the  corpuscle»  containing  several 

nuclei  predoniiimte,  and  ngain  those  with  a  single  nucleus  are  in  excess. 

Hc^ide^i,  this  distinction  of  Virchow  which  i»  founded  upon  tlie  analog^ 

of  the  white  oorpusclei  with  tlie  cvlU  of  the  spleen  in  one  case,  and  witli  lh«' 

cells  of  tlie  lymphatic  ginnds  in  the  other,  is  not  admissible  at  the  |)re#ent 

lime  on  other  ;;round.4.    It  is  known  that  the  glands  or  new  Irniphoid  orgao^ 

contain,  in  leucoeytlionna,  elements  larger  thuii  those  of  the  splenic  pareiM 

chynin.     Again,  in  Icucoeythiemic  patients,  the  changes  of  the  spleeilJ 

of  the  lymphatic  glands,  and  of  other  lymphoid  orgatis  tnost  frv<[ueDt]7^ 

occur  at  the  same  time.     There  are  often  formed,  iu  patients  siitTv^riag 

with  this  diseuse,  new  lymphoid  organs  (see  l.y m ]ili adenomata,  p.  141). 

A  few  writers  have  described  in  leuooeythtemia,  beetles  the  ordinary 

vhitG  cor|)ii:tclc,  red  corpuscles  contiiining  a  nucleu»,  and  which    Uiej'J 

'consider  as  iutermediale  éléments  hetween  the  white  and  red  corpuscles.^ 

Ve  have  searched  for  these  iniermediaio  corpuscle»  in  several  leiicocy- 

thiemic  patient/*  without  ever  finding  them.     Many  of  the  white  corixi». 

cles,  «specially  the  largest,  contain  very  small,  araher-colored,  spherical 

granules,  grouped  arouml  the  nuclei.     This   can  be   explained   by  the 

destruction  of  tlie  rod  corpusclos,  particles  of  which  have  been  absorbed 

by  tho  white  corpuscles. 

Mffanœinia. — This  name  signifies  the  presi^nco  of  particles  of  pigment 
in  the  blood  ;  this  change  is  swu  when  the  spleen  hns  experience*!  frc- 
4{ucnt  attacks  of  congestion,  especially  in  malarial  poisoning.  In  the 
cases  that  we  have  observed,  tlie  pigmentary  particles  existing  in  tliu 
blood,  were  round  or  angular,  deep  black,  varying  in  diameter  from  ex- 
treme smallnesit  to  ,008  mm.  or  .OH!)  mm.;  they  were  all  coniained  in  tin 
white  corpiwcle]*,  or  enveloped  in  a  colorless  granular  zone,  which  very  ' 
probably  represents  tlie  protoplasm  of  a  white  corpuscle. 

At  the  auto|Miy  of  persona  dying  during  the  presence  of  this  lesion, 
most  of  the  organs,  especially  the  spleen  and  liver,  are  foundof  «grayish- 
slate  color.     Éxaminin;;  thin  s.-ctioni  ffom  these   organ;,  pigmentary

granules  sre  found  in  the  white  corpuscles  containeil  in  the  vessels,  in 
the  cells  of  the  vessels,  in  the  cells  of  the  peri-vascular  connective  tissue, 
and  ID  the  celle  of  the  parenchyma.  The  splenic  lymphatâc  glands  are 
also  pigmented. 

Pathological  pigments  act  in  a  manner  similar  to  inert  granular  matter 
contained  in  the  blood,  vermilion  for  e.tainpte.  If  vermilion,  in  minute 
particles  suspended  in  water,  is  injected  into  the  blood  of  an  animal,  the 
granules  are  taken  up  by  the  white  corpuscles  and  carried  by  them  into 
the  different  organs;  they  pass  through  the  vascular  walls,  and  are 
finally  fixed  in  the  elements  which  are  the  seat  of  pathological  pigmenta- 
tion. It  is  probably  correct  to  consider  that  melanœmia  consiste  of  a 
pigmentary  change  of  the  blood  in  the  spleen,  and  a  carrying  off  of  the 
pigment  in  the  blood  by  the  white  corpuscles. 

The  pigmented  corpuscles  are  generally  larger  than  the  non-pigmented, 
and  are  liable  to  accumulate  in  gome  of  the  btoodvedsels,  and  obstruct 
the  circulation.  This  does  not  cause  true  embolism,  as  maintained  by 
Frerichs  and  Virchow,  but  a  phenomenon  analogous  to  that  of  stasis  of 
the  white  corpuscles  in  leucocythsemia  (see  p.  148). 

[^Parasitei. — According  to  the  investigations  of  many  hlstologists  there 
exist  in  the  blood  of  persons  affected  with  some  diseases  (the  infectious 
in  particular)  various  forms  of  minute  organisms  which  are  thought  by 
some  to  be  the  germs  of  contagion,  or  in  some  way  to  bo  more  or  leas 
directly  the  cause  of  disease.    These  are  micrococci,  bacteria,  filaria,  etc.]

HTPEBTHOpuy. — Hypertrophy  is  connected  with  exagiiertttod  work  oi 
the  lieart  lu  diseases  of  the  orifices  or  vessels  ;  the  ohjcct  of  tho  work  is

cliause»  of  the  aonic  orifice.  Hy()crtmpliy  of  the  left  venlriclc  in  atntphy 
of  the  ktilney  has  ticen  referred  hy  Traulie  to  an  anali)iou«  cauM.  This 
coincidence  of  hypertrophy  of  Ihe  loft  heart,  and  of  atrophy  of  tho  kid- 
ney is  an  incoiilê«tahle  fact,  hut  in  the  «xplnnation  t;ireu  hy  Trautw,  it 
i*  >)illiciilt  to  undenttntid  how  the  inconvenience  to  the  circulation  in  mi 
few  vcmcIm  can  cause  such  an  enormous  iucrcaso  of  work  in  the  licarl. 

Myi>ortrophy  i*  general  or  parlai.  The  i)ha[ic  of  the  heart  t.4  not 
notably  chanfîod  in  ;;eiii>pal  hypei^rophy.  In  hypertrophy  of  the  right 
ventricle,  the  apex  of  the  heart  is  not  so  pointcfl  as  normal,  it  is  en> 
lar^d  ;  it  is  formed  by  Che  extremity  of  botn  ventricles  which  are  upon 
tlie  same  level.  In  hypertrophy  of  the  left  ventricle,  the  apex  is  formed 
by  tlie  loft  only.  In  hypertrophies  of  the  heart  tlicrc  i*  always  seen  a 
t)iict;onin<;  of  the  enil'Kardiinn.  The  miwouUr  fibres  of  the  hyperlrophied  ' 
parl.1  either  do  ni>t  present  le»ion]i  of  nutrition,  or  they  have  undergone 
fatty  {ligmenCary  dejçencratîon. 

It  ii  not  yet  known  if  the  hypertrophy  is  due  entirely  to  an  inorease 
in  the  nzo  of  the  miwular  libres  of  the  heart,  or  to  a  new  formation  of 
tlieso  fibres.  In  hv[iertro|)liy  of  the  heart  the  plienomena  of  develop, 
ment  of  new  muscular  libr«3  have  never  been  obsor\-cd,  so  that  ilie  first 
hypothesis  is  the  more  probable. 

Fatty  DKiiENKUATios. — The  heart  is  more  frequently  the  wat  of  fatty 

degcnenttion  than  any  other  muscle  of  the  or;;tnism.     When  all  tho

noiog  fatty  de;^nenitioii,  tite  heart  alone  may  be  nttac):e<l.     In  a  fœtus

Iiarge  hcmorrtiAgcs  of  tlie  heart  occur  in  niptarcs  of  the  mj-oc&rtlium

■Iwnys  more  decided  in  the  proximity  of  tlie  heoiorrhajcie  foeu:». 

Anruriiitnii  <il'  thi;  Âtitrt  an  found  especially  in  the  interventricular 
iteptum  and  at  the  apex  of  the  left  ventricle.  The  aneuriiiinii  of  the 
xcptiini  and  baiie  of  the  heart  are  generally  tbe  result  of  the  exlennion 

5 of  a  valvular  aneurism,  the  origin  and  structure  of  which  will  be  later 
studied.  Those  of  the  apex  of  tbe  heart,  which  occur  most  fri'-iucnily, 
are  probably  consecutive  to  a  fatty  de;;cncnitionoran  inltammaiion  com- 
bined with  endocarditis  and  myocarditis;  but  all  the  changea  of  an  aneu- 
rism occurring  in  this  locality  cannot  be  follonod,  as  in  the  aorta,  and  it 
is  only  ttirou;;h  rcasoniug  by  aualoj^  that  the  method  of  their  fonnation 
can  be  understood. 
At  tlie  apex  of  the  heart,  tlie  nncurism  is  isoen  as  a  ano  varyinj;  very 
much  in  nhé.  from  a  haxel-nut  to  that  of  the  heart  itself.  When  the  si^e 
of  the  iiac  ÎH  very  itmall,  it  h  included,  aa  it  were,  in  the  walU  of  the 
organ,  and  can  only  be  recognised  liy  opening  the  heart  and  examining 
^B  it»  internal  surface. 

^P  The  communication  between  the  ventricle  and  the  cavity  of  the  aneu- 
^^  ri^m  is  by  a  funnel-shaped  apcrtun',  or  by  an  orifice  in  the  form  of  a  rin;;. 
The  wall  of  tbe  aneurism  is  firm  nnd  ri^d,  so  that  the  aneurisnial  sac  i» 
not  emptied  at  the  time  of  the  ventricular  systole.  Yet  the  stasis  of  the 
blood  is  not  sufficient  to  form  laminated  clolo,  as  takc^  place  in  aneurisms 
[of  the  aorta.  At  the  autop*y,  there  arc  very  often  found  in  the  «ac, 
recent  Ghrinoua  ciot«.  Where  the  aneurismal  »ac  i»  Anfractuous,  there 
are  suen  •hn»<'  fibrinou.t  clot*  adherent  to  the  w»ll. 

The  internal  .surface  of  tlie  sic  iâ  usually  âmooth;  sometime.*  it  is 
irrc;;uhr  and  anfractutius. 

A  histological  examination  of  the  wall  of  the  Aneurism  shows  layers 
of  flat  cells,  which  seen  in  prolile  appear  tliin  and  fusiform,  owing  to 
their  centre  being  awollcn  by  the  nuclons.  These  cells  arc  separated 
from  one  another  by  connective -tissue  fasciculi  and  bloodvessels.  The 
entire  wall  of  die  aneurism  may  consist  of  this  tissue,  but  frequently 
only  the  întcniul  Hurface  of  the  ^c  is  of  this  structure,  and  there  arc 
found  in  the  exl'Tnuil  jmri  ma«culnr  fibres  of  the  In-nrt  group<;d  in  small 
fasciculi  or  isolaleil  among  the  layers  of  Itat  cells.  By  examinin;;  n  fre»h 
piece  of  the  aueuri«m:il  «ac,  it  is  possible  by  dis^^ection  to  obtain  tbe  flat 
cells.  They  accurately  resemble  the  cells  of  perfectly  formed  connective 
tia^ue.  Isolated  anil  floating;  in  a  fluid,  they  pn-sent  surfaces  and  borders 
ftud  folds  which  imlicate   that  tliey  are  flat  cells  of  extreme  thinness.

NoKMAL  HisTOLOov. — ^Thc  endocardium  lining  the  wliole  internal  sur- 
face of  lliR  heart  presents  for  con^idenition  three  layers  :  tsl,  tiie  cndo- 
tbcliuni  forinin;;  a  sinj^lc  layer  of  flat  cell»  ;  2d,  a  layer  formed  by 
flntU'ned  cells  separated  hy  ii  laminated  fundamental  substance;  Ai,ik 
layer  fonned  by  elastic  tissue  and  fasciculi  Df  connective  tissue. 

l.-<t.  The  first  of  these  layers  disHii|«;iir»  twuuly.four  hour»  after  death. 

"id.  The  layer  of  flnlteued  cells  i.-i  very  thin  ii]tnu  the  ventricle*  and , 
both  -iiirlace-*  of  the  arterial  and  aurlrulo-veniricular  valves  ;  it  ii*  thicker 
upon  the  auricles,  and  more  so  upon  the  left  tlian  the  rij^Vii.  The  flattened  , 
celU  are  thin,  and  generally  pMWM  prrdonga lions  which  vary  in  number; 
they  contain  a  lenticular  mieleua,  a  little  swollen  at  the  centre  ;  they  are 
arranged  parallel  one  to  the  other,  and  are  flattened  in  a  direcdon  parallel 
to  the  internal  surface  of  the  en<locar>liuin. 

The  lauiinaled  fundamental  substance  which  separates  the  celU  is  not 
reduced  to  fibrils  by  macerntin;i  in  bnryta-watcr,  as  i*  the  ca»«  with 
ordinary  c'lnuRctivo  tissue  ;  it  seems  but  sH^^htly  fibrillate'l  atnl  almost 
hyaline.  This  layer,  like  the  endotliclial  lnyer,  is  continued  without 
interruplion  upiiu  the  sujicrior  and  iuferiur  surfaces  of  tlie  valves. 

Hd.  The  connective  and  clastic  tissue  layer  of  the  endoearvliuin  raries

fiiderably  that,  for  example  in  the  apex  of  tlie  left  auricle,  where  it  is 
most  developed,  it  is  about  ten  times  thicker  than  upon  the  ventricles. 
This  layer  is  directly  continuous  with  the  layer  of  flattened  cells  on

upon  tlie  eiXge  of  the  valves,  but  a  little  distance  from  the  border.  It  is 
chiefly  in  an  endocarditis  of  rapid  course,  as  in  puerperal  fever,  or  very 
severe  acute  artieiibr  rheumatism,  ibat  this  arrangement  ts  ohïcn'ed.  1'he 
lnr|;c«t  vegetations  are  seated  only  upon  tbe  valves  or  upon  the  fibrous 
«one  of  the  cardiac  oriHcea. 

If  tlie  course  of  the  endocarditis  is  irregular  and  slow,  tlie  vegetations 
are  very  uncoual  id  siee.  In  chronic  form*,  the  vegetation»  are  not  so 
pmmincnl — toey  rcat  upon  an  indiiratAd  base,  arc  harder,  cartilaginous, 
and  ofti;n  opa^f ue  ;  while,  in  the  acute  fomiR,  the  recently  formed  vege- 
Utioii^  are  soft,  friahte,  and  semi-transparent.  The  irari»liicency  anil 
friability  of  recent  vegetations  cau^teil  iliem  for  a  long  time  to  tw  con- 
sidereii  as  consixtin;;  only  of  fibrin  ;  yet  their  attachment  to  the  wall 
should  have  bani.itied  Ibis  hyiiothe^s.  When  they  are  removed  witJi  the 
fingers,  the  surface  of  the  membrane  ta  not  «en,  but  there  is  a  tear,  which 
very  distinctly  demonstrates  that  the  vegetation  is  part  of  the  niembmnc. 
A  microscopic  examination  shows  this  relation  most  satisfactorily, 
Si-clion*  from  acute  endocarditis  exhibit  vegetations  formed  entirely  of 
embryonic  c^'lls  separated  by  a  very  scanty  amount  of  aiiior]>hoiw  «ib- 
alance  ;  this  tissue  is  continued  into  the  en<locanliiim  henentb,  and  forms 
a  Koiie  varying  in  extent  around  tiie  vegi-ialion.  This  «one  of  prolifera- 
tion should  he  carcfnlly  studied,  in  onler  lo  understand  the  formation  of 
vegetations  on  the  endocaniium.  tt  U  seen  that  it  is  not  distiikclly

or  ihcir  siie  is  such  that  they  arc  arrested  in  the  arterioles,  producing 
septicipmia  and  embolism.     This  entire  morbid  process  has  received  the 
name  of  ulcerous  endocarditis,  but  it  docs  not  constitute  a  distinct  variety 
from  other  acute  forms  of  endocarditis. 

WiU'uiar  Aneuritnië. — The  lesion  described  as  valrular  tncuriam 
{Tbiimam,  Foerster,  Pelvet),  is  a  eonnciiiicnce  of  acute  eudocanlitis 
aflectin;;  the  valves.  Tbe  nmltipliuatiun  of  the  cell»,  their  embryonic 
HtnK*,  the  softening  of  the  int<rrcclluliir  ïubvUmce,  and  the  disa[qiearancc 
of  the  ela.-'tic  fibre»,  phenomena  connected  with  endocanliti»,  caune  the 
valve  to  lose  ittt  power  of  re»iHtnnce,  and  it  is  not  able  to  snp{)ort  tlie 
blood  pressure.  Wlien,  from  the  action  of  acute  endocarditis,  tlie  soften- 
ing rapidly  extends  to  all  the  layers  of  tbe  vaU-e,  the  latter  is  at  first 
distended,  but  is  soon  ruplurod.  When,  however,  thi  action  of  the  in- 
flamniation  is  slower,  the  valve  having  losi  part  of  its  resisting  power, 
slowly  dilates  without  being  ruptured. 

Vah-ular  aneurism  has  so  far  been  observed  only  in  the  left  heart, 
upon  the  aortic  and  mitral  valves.  In  the  aortic  valves,  the  orifice  of 
the  nnuurism  is  always  upon  the  superior  or  arterial  surfaces;  in  tbe

Acute  endocarditis,  by  the  vegetations  and  ihickenlnj;  of  llit*  endo.

A  series  of  lesions  of  the  heart,  occurring  espwially  at  llie  orifices,

Chronic  cndocaniitjs  is  essentially  charactoriited  by  cartilagc-liltc, 
translucent,  or  ojni'iue  thiekeiiiiig».  In  many  iniitancea  the  indunttions

aiHl  valves  ;  they  are  very  analogous  to  the  alterations  occurring  in  ewl. 
arteritiii  defomtans,  and  it  is  probable  that  ii|>on  the  endocardium  a.t  in 
the  arteries,  primary  atlieroma  exerts  some  influence. 

'llip  le.'iions  of  the  valvea,  in  chronic  endocarditis,  have  the  form  of 
globular  or  warl-likc  ve;;ctations,  seated  fjenprally  upon  the  ventricular 
unrfnce  of  the  aortic  i-alvcs  and  upon  the  auricular  surface  of  the  auriculo- 
T«»tHcular  valves.  The  chordae  tendincte  of  the  an riculo- ventricular 
valves  are  increased  in  size,  indurated,  and  shortened  ;  the  fibrous  zoni; 
limiting  the  orifices  is  hyijertrof'hicd  and  indurated.  When  the  heart  is

TUK  FoRMATiox  OF  HijooD  Clots  is  tub  IIbahi.— Fro(|«ently  at  the 

Mutopsy  the  left  ventricle  is  found  contracted  and  empty  of  blood,  except 

pH  be  u  lew  filamentous  clots  between  the  columnK  cameie  of  the  uiitnJ 

valve;  it  is  only  in  cases  wlicre  tht*  person  diw  of  syiicjpe.  that  the 

ventricle  »rreste<l  in  diastole  at  the  moment  of  death  contains  blood  and 

t  clots. 

The  right  ventricle  ia  fre<[uenlly  distendeil,  and  tilled  with  coagulated 
blood,  chiefly  owing  to  the  agony  geaerally  being  accom]>aiiicd  by 
asphyxia  and  hinderance  to  the  pulmonary  circnUtion,  which  jirevcnts 
the  right  ventricle  from  emptying  itwlf.  Iho  anriclea,  on  account  of  the 
feebleness  of  the  contractions,  are  always  filled  with  blood  during  life 
and  occasionally  after  death. 

When  the  heart  ceases  to  beat  tho  blood  contained  in  ita  cavities  is 
slowly  coagulated — much  more  slowly  than  if  it  ts  exposed  in  a  vessel. 
Tliis  has  been  established  by  the  experiments  of  Brlicke,  who  remarked 
that  blood  from  the  cavities  i<f  u  heart  removed  from  the  body  of  an  anima 
coagulated  only  after  several  hours,  a  phenomenon  which  he  attribute* 
lii«  influence  of  the  endothelium  of  the  endocardium.  It  is  now  known 
that  when  blood  coagulates  slowly  ilie  red  corpu.->cle.t,  which  are  the

cnlorloM  upon  their  superior  portion,  while  tliey  nrc  cruorio  upon  their

These  clots  are  considered  by  lamt  physicians  to  be  formed  during  tlie 
a^^ny  ;  on  account  of  their  decoloration,  they  have  accorded  to  them  a 
vital  ori^fin,  and  have  named  tliciu  acdve  clots.  What  we  have  said  in 
reference  to  the  modo  of  formation  of  these  clots  is  snfficient  to  demon- 
strate that  this  interpretation  is  erroneous,  and  it  ia  useleaa  longer  to 
insist  upon  it. 

Some  ctots  nkcrit  the  name  of  aclivo  clots,  if  by  this  word  it  is  under- 
stood Ihotc  which  arc  formvd  duriiij;  life;  they  arc  the  fibrinous  coagu- 
lationit  developed  in  thin  layers  upon  the  surfaco  of  the  denuded  endo- 
cardium in  endocanliti»,  or  upon  ve^tatinns  of  the  orifices,  or  upon  tlio 
torn  valves,  'Hiese  clots  are  white  or  yellow  :  ihey  contain  wo  red  blood 
corptiftclea,  only  layers  of  granular  fibrin  and  white  corpuscles.  Aceonl- 
ing  to  the  tlieory  of  A.  Schmidt,  which  ia  generally  accepted,  their 
formation  results  from  the  condensation  of  the  tibrinogenic  substance  of 
the  blood  in  contact  onlv  with  the  inflamed  wall.  The  slow  coagulation 
for  this  reason  does  not  include  the  red  clémente. 

Other  tarifer  clot»  are  fonned  by  «  sloiviiig  of  the  circulation  of  th« 
biwxl,  a«  occurs  in  «;tystole,  ei^pecially  that  produced  hy  an  impediment 
to  the  pdmonary  circulation,  and  in  hypertrophies  of  the  heart  with 
diUt  talion. 

'lliese  clota  vary  in  size  and  form  ;  they  generally  cover  the  eolumoie 
cameœ,  are  adherent  to  the  wall,  and  are  uniformly  yellow.  If  they  are 
not  very  old.  they  may  ho  separated  into  lamellfe  by  tearing,  and  their 
central  part  does  not  didcr  in  consistence  from  the  superlirial  layers.  If 
they  are  older,  their  superficial  part  is  more  consistent,  while  their  centre 
is  soft,  and  forma  a  granular  mass.  When  the  chan;;cs  of  the  blood  have 
been  great,  as  in  hemorrhagic  smallpox,  puerperal  fever,  poisoning  by 
phodphorns,  etc.,  heart  clots  fornted  after  death  arc  soft,  friable,  and  do

'Flio  midilU  r^itt  of  tbe  large  and  médium  size  arteries  consists  of  elastic 
latnintu  and  fibres  forming  by  their  anastomoses  a  continuous  system  in 
which  are  found  smooth  muscular  libres  passine  in  a  transverse  direction. 

Next  to  tbe  internal  coat,  the  middle  coat  le  umiced  by  a  thicker  elastic 
lamina  and  also  more  refivcting  than  the  others  ;  in  transverse  sections  it 
has  a  festoooed  appearance.  The  rcco;^ition  of  this  lamina  is  rery  im< 
portent  in  pathological  investigations:  we  have  named  it  tbe  inlcrHot 
elaatie  lamnia  of  the  middle  cjiU.  [Most  authors  regard  tbis  clastic 
lamina  as  the  external  layer  of  tbe  tunica  intima,  reoogniting  three  layers 
of  this  coat.]  In  the  external  coat  elastic  fibres  mingle  with  the  fn«ciculi 
of  ttio  connecUTc  tissue  in  every  direction,  to  form  the  framework  of  the

The  external  coat  is  traversed  by  arteries,  cajnllaries,  and  reins  {ra»

transversely.  Small  nerve  trunks  and  isolated  nerve  fibres  are  also  seen 
in  tbis  coat.  The  small  arteries  possess  a  middle  coat  fanned  by  smooth

^91ie  tunica  adventiiia  of  these  arteries  consists  of  very  fine  fasciculi  of

AttTKRlTli*. — The  inflammation  of  arteries  presents  for  consideration 
many  vnricti«tt  when  oxaimnod  from  a  p.itiiolo^ical  [loint  of  view.  The 
inflammation  may  be  considered  in  reference  to  its  location  in  lai^c,  me- 
dium, or  «mall  arterie.s,  and  in  the  external,  middle,  or  internal  coals; 
atlieromatous  and  calcareous  tumefaclion  also  enters  into  the  history  of 
arteritis;  finally,  spontaneous  aneurisms  and  the  obliteration  of  arteries 
by  a  clot  followed  by  organisation  belong  to  arteritis. 

itt.  Acvte  AUTitRlTls. — ,\cute  endarteritis  or  acute  inflammation  of 
the  internal  coat  of  the  aorta,  has  been  seen  by  in  several  times  as  an  iso> 
latcd  lesion.  To  the  unaided  eye,  it  is  characterized  by  a  swelling  of  tbe 
internal  coat  in  tbe  form  of  prominent  jiatches  more  or  ivis  extended,  with 
a  contour  somewhat  n-gular  and  generally  circular.  The  i*inaller  oiiesarv 
rcgulariy  round,  and  present  a  sharply  raised  surface  ;  others,  larger,  more 
irrcgidar  in  their  contour,  are  evidendy  formed  by  the  confluence  of  seven! 
small  round  patches,  and  exhibit  prominences  and  depressions  ufmn  their

ence  is  elastic  and  soft  aa  jelly  ;  they  have  been  named  gelatinous  patches 
of  the  aorta  ;  llieir  surface  is  very  seMom  ulcerated.  These  patches  are 
fre<[uently  accompanied  by  a  somewhat  analogous  change  in  the  neighbor, 
ing  internal  cont,  so  that  tbis  membrane  appears  saturated  with  fluid

tilU  vna  very  iDtense,  we  have  been  impressed  with  tlie  jialeness  of  Uie 
internal  oat,  and,  a^mo,  we  bave  frequently  met  with  an  intense  nMlnMS 
of  the  vessels  and  endocardium,  dnv  solely  to  imbibition,  without  any 
histological  tnwe  of  ondarU^ritis  or  endocarditis  :  it  is  suffieiont,  how- 
ever,  to  allow  an  urtcry  to  macorato  in  water  olort-d  bv  blood,  in  order 
that  its  primarily  pale  surface  may  become  red  by  imbibition. 

There  is  freiiit^ntly  «eeii  in  endarteritis  a  rou|;hcncd  appearance  of  tli« 
internal  surface  of  the  artery,  due  to  an  irregular  tumefaction  of  tlie 
■nternni  coat,  and  not  to  a  falling  off  of  the  cmlotiieliuRi,  aa  has  bcea 
Buppoted.  Alt  we  hare  already  mentioned,  lhii«  endotJicliiim  is  normally 
deslroycd  within  twenty-four  hours  after  death.  This  is  no  leas  true 
also  of  jiathiilo^cal  conditions,  both  upon  the  smooth  surfaoca  aa  well  aa 
upon  thoiie  which  are  roughened. 

A  vertical  section  of  these  patches  is  seen  to  have  a  color  and  semi- 
transluccncy  similar  to  tliat  of  the  surface,  and  to  the  noatded  eye 
their  separation  from  tlic  middle  coat  is  distinctly  reco^ixcd. 

The  elements  constituting^  these  patches  can  be  separated  wttbout  dlA*: 
eulty,  by  dissection  with  needles.  Large  shreds  of  the  internal  coat  mar] 
also  he  stripped  off:  this  coat  i«  transjureul  or  slif:htly  striated,  and  is^' 
caaily  separated  into  thin  laminn,  a  d«m»ustmtion  that  tlie  cells  of  th«  ' 
eoat  arc  arranged  in  layeni  parallel  to  the  surface  of  the  vosel. 

'riie  elementii  forming  tlie  patches  are  round  or  irregularly  spherical 
cells  having  an  average  diameter  of  .01  mm.,  and  in  which  a  nucleus  is 
|teen  upon  the  addition  of  acetic  acid.  These  eleini-tita  have  all  the  cliamc* 
Pters  of  embryonic  celU.  Larj^i-  fliitloned  cells  with  several  prolongations 
containing  at  times  two  nuclei,  are  also  observed  ;  they  exist  normally  in 
the  internal  coat.  Examination  of  the  tissue  by  dissociation  showa 
round  cells,  which  are  wot  free  nuclei,  as  has  been  believed. 

On  microscopic  examination  of  thin  aectionn,  the  patches  appear  u  t\ 
thiclieuing  of  the  internal  coat.  With  low  magnifying  power,  the  gres 
thickne.xa  of  these  patches  can  be  appreciated  hy  comparison  with  the 
normal  poiiion  of  the  internal  coat  and  with  the  middle  coat;  for  tln-y 
raiay  be  a  hundred  times  thicker  than  the  internal  normal  coat,  and 
f*two  or  three  times  thicker  than  the  middle  coat.  Witli  a  power  of  one 
hundred  diameters,  which  permits  the  whole  of  the  preparation  to  be 
seen,  the  cellular  elements  arc  found  to  be  verv  numerous,  arranged 
in  lines  pariillel  to  the  surface  of  the  patch,  and  atminishîng  in  numbera^ 
as  the  middle  coat  is  approached,  offering  a  verv  striking  analogy  to  the 
phenomenon  which  take*  place  in  inllamcd  diurthroilial  cartilages,  where 
the  cells  at  the  surface  are  also  the  first  to  proliferate.

into  nbrin  by  the  action  of  the  fibrinoplastic  substance  of  the  infljunod

Tlio  middle  -yiiit  does  not  j;encrally  present  any  alterations  in  acute

all  the  phases  of  the  lesion  may  be  seen  in  the  same  section  of  au 
art«ry. 

Aeutc  periaTteriti»  ehnraoterixed  by  a  purulent  infiltration  of  tho  ex-

limited  to  this  membrane,  or  it  nccsstons  only  a  slight  lesion  of  the  in- 
ternal coat.  In  ttiis  case  the  middle  coal,  which  is  not  modified,  is  suffi, 
ciently  reaislins  so  that  there  does  not  result  any  serious  interference 
with  the  local  circulation,  and  the  artery  performs  its  functions. 

In  arteries  of  medium  size  and  smaller,  sponinneous  acute  endarteritis 
seldom  occurs;  but  in  granulation  tissue  of  wounds,  arteritis  is  common, 
for  example,  in  the  fun^^id  tissue  of  paronycliia,  and  in  chronic  ulcers.

ceding,  except  that  they  arc  complicated  by  fatty  de<:eneradon,  atlieroma, 
and  calcareotia  transformation.  Atheroma  and  calcareouA  infiltration 
are  always  accompanied  by  arteritis;  but  this  is  not  the  case  witii  fatty 
degeneration  which  may  occur  separately,  and  which  we  believe  to  be  one 
of  the  causes  of  arteritis.

of  the  flat  ramifying  cells  of  the  internal  coat.     (Fig-  167.) 

In  transverse  sections  it  is  found  that  the  fatty  dcgcn«nition  is  i>ot

from  the  lirai  or  follow  an  acute  rlieiiniatiaro,  pacrperal  fever,  alcoholic 
endarlericis,  etc.  The  lesions  of  chronic  endarteritis,  whatever  may  be 
iw  origin,  are  always  complicated  bv  a  fatty  denencrnlion  of  the  artorial 
coata;  they  lenninate  in  the  formation  of  athcromatoua  foci  and  calcareous 
plates.  It  is  important  to  make  as  complete  analysis  as  possible  of  all 
these  phenomena  in  order  to  demuDstratv  that  they  follow  a  f«tty  dcgcno- 
ration  which  occasions  arteritis  or  succeeds  it. 

In  acute  arteritis  which  is  not  very  ÎTitcnw,  the  gelatinous  patches 
ihemteive*  inclose  rainitied  cclU  coatnining  fatty  granules,  'nds  fatty

lich  at  first  had  the  form  of  the  cells  are  fused  together,  and  there 
results  a  small  patch,  visible  only  with  the  microscope  :  later  it  enlarges, 
and  hccomcs  evident  to  the  unaided  eye  as  a  characteristic  atheromatous 
tocos. 

This  athermnat'/uê  foeuê  is  situated  in  the  tldckcned  internal  coat  ;  it 
is  largo,  «uperGcial,  and  Jl»  honlers  are  irrejçular.  When  it  remains 
intact  it  is  separated  from  the  current  of  blood  by  a  thin,  carlilagedikc 
jjellicle  which  is  formed  hy  the  most  superficial  layers  of  the  intenml

Such  ruptures  of  foci  niay  be  the  beginning  of  aneurismal  dilatatiora^j 
which  will  oe  considered  later.  In  aeetions  paxsing  vertically  through  the^

Bubatance;  further  from  the  ailieromatoua  focus  there  are  found  nuclei  j 
colored  red  by  carmine,  and  surrounded  by  fatty  Rrnnulcs.     The  funda* 
mental  substance  is  made  up  of  a  fibrillation  rery  much  like  that  seen  io 
illic  centre  of  tho  costal  cartilage;  and  again,  the  fihrilliir  mass  limits 
pmall  cavities  which  contain  cellular  elt-menls  recalling  tlie  cells  of  carti- 
lage, except  that  they  potites-i  n'k  capsule.     It  is  a  kind  of  chondroid,  but 
not  carlila;cinoiu,  transformation  of  i!)e  internal  coat.     If  the  utliero- 
Diatoua  evolution  occurs  slowly,  while  the  cella  experience   liie  fatly  i 
,  metamorphosia,  the  fibrillar  fundamental  substance  ia  infiltrated  with 
kalcareous  granules.     Those  granules  at  first  discrete,  are  later  united 
together,  so  that  tboy  form  tmbriated,  semi-transparent,  friable,  slightly 
elastic  plates. 

Tftf  rtUcarffUi  fhfeê  are  seldom  completely  exposed  at  tho  surface  of  ■

Since  the  calcareous  plates  are  transparent,  friable,  and  but  little 
elastic,  by  the  unaided  eye  they  am  easily  distinguished  from  osseous 
tissue,  which  is  resistant,  opa<iue,  and  i)uile  clastic.  Under  the  micro-

or  iinhricnted  one  upon  tho  other,  sonietiincs  limited  at  iheir  periphery

extend  to  the  coronary  artcrie*,  10  the  innominate,  to  the  carotids,  and 
to  the  sahclavian,  invading  them  to  a  greater  or  lea»  extent.  The  origin 
of  llicae  arteries  fioni  the  sorta  almost  always  preaent^  a  nearly  perfect 
bone-like  ring.  The  arch  of  the  aorta  is  the  portion  the  moat  dilated  ; 
it  fre<|uenlly  has  the  form  of  an  elongated  funnel.  In  the  thoracic 
aorta  tliei-e  are  found  eatcarcous  plates,  open  alhcramatouB  foci,  alhoro- 
matoua  pustules,  trunsliicid  orsomewhatopa'juecartilagcdikc plates.  Tho

usual  pigmcntarv  metamorphoses,  and  occasions  black  or  melanotic 
patches  varying  in  size,  giving  the  diseased  part  a  peculiar  appearance, 

The  preceding  dcMription  is  particularly  appropriate  to  the  aorta,  but 
tbu  same  lesions  are  seen  in  tlie  medium  and  smalt-sized  arteries,  where

a  slightly  fibrillar,  resi^liii;;,  intercellular  substance,  which  ROO»  gives  to 
the  membrane  a  cartilaginous  consistence.  'Hits  cliondroid  tiiiiiue  may 
develop  regularly  in  the  internat  liftsue  in  such  a  manner  as  to  diminish 
the  calibre  of  the  vessel,  or  its  development  is  greater  at  some  point» 
than  others,  constituting  prominent  plates  or  projections  into  the  lumen

SpoiiUiicous  aneimnms  «re  alwBys  developed  in  arteries  which  have 
been  for  a  long  time  the  seat  of  iiiflatnmatory  lesionn 

It  has  heen  »een  that  in  the  formation  of  the  most  simple  aneurism — dila- 
tation of  the  aorta  in  arteritis  deforroans — the  internai  and  external  coata 
arc  greatly  chani^d  and  hvpertrophied,  irhile  the  middle  coat  has  par 
tially  disappeared.  Therefore  this  aoeuriatn  cannot  be  considereil  as  a 
trae  ancunsni.  since  the  midille  coat  is  at  places  absent  ;  and  it  is  not  a 
nixed  extvnial  or  mixed  inleroul  aneurism,  since  botli  the  external  aiul 
internal  coats  are  at  the  same  time  moilifii'd  in  thi-ir  structure  aiu)  are  dis- 
tended. It  is  the  same  with  every  other  fonn  of  spontaneous  aneuri-tm, 
i.lliat  the  anatomieal  elassificatien  of  autlior^  should  he  rejected. 

All  Rpofitaneoas  aneurisms  are  believed  by  us  to  he  the  mme  hiittoloj^- 
cally,  that  ts,  their  sao  is  formed  by  the  intentai  and  external  coata, 
modified  by  inflammation  and  dilated  by  the  blood  pressure,  tlie  miildle 
coat  having  disappeared  completely  or  in  part. 

Fnrif'>rm  aneurisms  are  produced  hjr  a  circuiMcrilied  dilatation  of  an 
artery,  in  which  a  limited  portion  ts  distended  in  a  uniform  manner. 
Tlic  arteritis  has  extended  ru^ukrly  over  the  entire  surface  of  a  portion 
of  the  rcssel. 

If  tlie  arteritis  is  located  only  upon  one  «de  of  the  artery,  or  there 
Mtain»  it»  greatest  intensity,  it  destmys  the  middle  coat,  and  the  dilata- 
tion oecurs  solely  at  thi.«  point,  forming  a  mn-rit'orm  aneurism. 

finally,  small  aneumtii.<)  commnnicaliii''  with  the  artery  by  a  sharp 
edge — the  sac  of  which  is  rcgulnrty  hemispherical  in  «hape,  mont  fre- 
quently sitaated  at  the  origin  of  the  aorta,  and  which  appear  to  be  formed 
by  an  opened  and  distended  atheromatous  focua— are  named  cgttogetùo 
or  «aHliaped. 

DtêMf^tng  anfHritmt^  described  first  by  I.aennec,  owe  their  formation 
to  H  rapid  dilatation  duriiiz  an  ciiduri«ritis.  Laennec  supposed  that, 
after  the  nipture  of  the  intenial  and  miildle  coats,  the  bloo-l  escaped 
between  tliem,  disi«ectiu^  the  cxtenial  coat.  But  l'eacouk  has  demon- 
strated thai  tiie  hlooil  is  diffused  cither  between  the  hyperlrophied 
internal  coat  and  uiid<lle  coat,  or  between  the  laminie  of  the  middle  coat, 
l* hy ai ologi cally,  the  extenval  coat  if  formed  of  fnscieuli  of  eoniiecUre 
tissue  which  slide  one  u^nn  the  other,  and  i»  incapable  of  retuitiint;  the 
blood  under  the  arterial  pressure.  Several  hive»tigaton*,  liiill  and 
Duguct  among  others,  have  verified  the  views  of  this  Kn^lish  author. 
Every  circumscribed,  sacciform,  fusiform,  or  cup-shaped  aneurism  pro- 
ccnts  for  consideration  Uie  membrane  or  wall  which  surrounds  the  sac, 
and  the  Ktratijifd  flntt  which  line  the  internal  surface.

In  the  large  aneurisms,  the  onler  of  the  stratified  clots  is  not  so  sim-

In  these  clota,  a  true  organization  in  the  sense  of  a  tisane  is  not  seen: 
neither  living  cells  nor  vessels  are  observed  ;  but  after  the  action  of  cu^

From  what  Iia«  bf«ii  previoiuly  mid  of  chronic  vixlartvntiif,  iind  of 

[Uic   Mtructurv  of  the  «neuri.trmil  »%e»,  it  is  very  fii*y  to  understand  the 

Jdevelo|Muent  and  growth  of  aneurii«n)it.     Of  the  different  eoaw  of  the 

^arterie:*  the  middle  one  only,  by  ita  elastic  and  contraoulv  elements,  is 

able  eSbclually  to  reaiiit  the  blood  pressure.     When,  from  tlie  combined 

^«Bects  of  endart«ritis  and  periarteritis,  the  middle  coat  has  diimi'itvarcd 

coRsequonce  of  the  fatly  degeneration  of  its  mu^cuJar  fibres,  and  from 

[the  granular  breaking  down  of  its  clastic  6brea,  the  resistance  of  ttie 

1  vessel  becomes  insufKcicnt  and  it  is  distcndnl.     This  dilatation  does  not 

Isrrcst  the  formation  of  morbid  tisane  ;  neither  is  the  thickness  of  the 

liralls  of  the  eac  in  inverse  relation  to  ît«  extent.     Sometimes  the  wall 

of  the  »ae,  at  Ica^l  in  point»,  is  much  thicker  than  all  the  united  coats  of 

►  the  primary  vessel. 

The  wall  of  the  aneurismal  »ao  may,  honevvr,  become  thin  and  break. 
This  rupture  is  followed  by  an  escape  of  blood  into  the  Deifrhboriog  tis- 
sues.    The  leaion  has  been  named  a  false  consecutive  aneurism. 

One  of  the  most  iut«resting  points  in  the  anatomical  history  of  aneu. 

risma  consista  in  the  changes  occurring  in  the  surrounding  parta  by  the 

1  extension  of  the  sac.     In  aneurisms,  especially  of  the  arch  of  the  aorta, 

where  the  bones  cannot  be  pushed  Midc  or  separated,  thp  latter  undergo 

&  very  singular  l'>ss  of  xuh^tanre,  which  the  older  anatomists  explained 

by  roeclianical  irearin^r  away.     When  the  aneuriitmal   sac  extendi  and 

comes  in  contact  with  the  «temum,  ribs,  clavicle,  or  bodies  of  tlie  ver- 

I'tebrw,  excavations  or  a  loss  of  substance   limited  by  a  red  va-wular 

1  surface  result.     Sections  of  these  bones,  to  the  unaided  eye,  show  the 

'  characteristic  lesions  of  osteitis:  enlargement  of  the  vascular  or  nic<lul- 

lapy  spaces,  and  the  formation  of  embryonic  marrow,  are  recognised  by 

microscopic  examination.     The  osseous  liimellic  are  irregularly  eroded; 

^^ftnd  the  marrow  formed  of  youn;:  cells  does  not  contain  adipose  vvsi- 

[cles.     It  is,  therefore,  not   a   mechanical  wasting   nway,  but  a  vitnl 

-process,  through  which  the  bone   ilisappears.     The    mecbanical  action 

oecftffiOM  an  irritation,  and  it  li  this  that  causes  the  absorption  of  the 

bona. 

The  irritation  excited  by  the  pressure  of  the  aneurisraal  sac  causes 
the  neighboring  organs  to  unite  to  it,  giving  rise  to  infiammalory  com- 
plications. Inflammation  of  the  organ  at  the  point  of  adhesion  is  added 
to  that  of  the  wall  of  the  .sac;  softening  of  the  tissue,  and  a  perfora- 
tion are  produced.  In  this  manner  aneurisms  of  the  ascending  aorta 
nay  open  into  the  pleura,  pericardium,  trachea,  oesophagus,  superior 
vena  cava,  pulmonary  artery,  right  auricle,  or  ventricles.  Adhesive  in- 
Sammations  of  the  tieij^hboring  organs  at  limes  may  extend  to  more 
distant  partK  ;  thus,  a  phlegmon  of  the  mediastiinim,  catarrhal  and  ca- 
«eoHs  pneumonia  may  occur  in  aneurism  of  the  thoracic  aorta,  and  phleg- 
mon of  tlio  subcutaneous  connective  tissue  arise  in  aneurisms  of  the  ex- 
tremities.

four  hour*  after  lyitij^  the  earoiiil  or  femoral  artery  of  a  dog,  there  i» 
formed  a  clot  in  the  central  end  as  far  as  the  firnt  cullateral  branch.  At 
this  time  the  endothelium  of  the  internal  memliraue  pre.tents  importaiil 
nioi  lili  cation  H  :  the  cells  are  swollen  and  granular,  containiuj;;  a  spherical 
inicleu4  and  frctiuontly  several  nuclei.  The  lolloivin;;  days  a  thickening 
of  tlie  internal  coat  is  seen,  especially  in  the  proximity  of  the  ligature, 
dial  is,  all  that  portion  of  the  artery  compriseil  between  the  clot  and  ibo

verse cuts  is  seen  as  a  clear,  refracting,  and  festooned  band,  \»  a  very 
important  point,  indicating  the  internal  boundary  of  the  middle  coat. 
The  thickening  of  the  iiiiornal  coat  i»  formed  almost  entirely  of  cclU

883  LBStOtïS   07  THE   ARTERtES.  V 

When  a  Bin;ile  ligature  in  the  continuitv  of  an  artery  of  a  dog  i»  ap- 
plied in  the  ordinary  way,  tlie  following  phenomena  arwe. 

Soon  nflcr  the  blood  inchitled  between  the  ligature  and  the  firet  col- 
lateral hrHiich  above  is  pUcod  aeido  froin  the  circulation,  a  fibrinous 
coa^iiluin  bc^^ii»  to  fonn  at  the  bottom  of  the  nrterial  cup.  Thii»  coaguliim 
t»  not  homogeneous,  u«  Kimllh-inch,  Itiltroth,  ami  others  huro  tleclnn-il  ; 
neither  <loe»  it  at  once  fill  the  calibre  of  the  occluded  vessel  np  to  the 
flriit  collateral  brunch.  The  fibrinous  clot  i«  built  up  little  bjr  little  fron 
llie  bollom  to  the  lop  by  the  luperponitioii  of  «uccesriive  portious  (</,  fig. 
170).  It  mav  ret|tiirc  hours  and  even  d»;s  for  the  formation  of  the 
entire  fibrinous  dot,  and  its  apex  mav  never  reach  aa  high  as  the  level  of 
the  first  collateral  branch.  The  general  outline  of  liiia  blood  elot  ia  that 
of  a  cone  or  a  spindle  blunted  at  the  end  near  the  ligature.  The  cotiati> 
tutioD  of  the  separate  portions  of  the  hiooil  clot,  which  liave  been  de- 
posited at  int«rvals,  is  not  booiogeneous,  but  it  presents  unnùstakable 
evidences  of  lainiuution  of  a  peculiar  kiml.  'the  separate  portions  appear 
to  be  com])Oscd  b;  coils  of  a  cylinder  consisting  of  coagulated  blood — tha 
coils  arranged  very  much  like  those  of  a  ropo  or  distilling  pipe.  Thi« 
curious  opler  of  deposition  of  the  successive  portions  of  a  blood  clot  wn« 
Vfttohed,  during  life,  in  a  small  arieriote  of  the  ton^^ue  of  a  frog.  B; 
thia  observation  it  was  learned  that  the  serpentine  slratification  of  the  ol«t 
above  alluded  to  was  not  an  optical  iUn-iion,  but  a  genuine  fact.  Soiae, 
not  all,  of  the  completed  blood  clots  were  capj>ed  by  a  stratum  of  homo- 
geneous clot.  In  llils  stratum  of  homogeneous  blood  clot  are  to  be  seen, 
Bcattered  nmong  the  ivd  and  white  blood  corpu^^cle,  a  rariable  number  of 
swollen  granular  uni-  ami  poly  nucleated  endothelial  cells  (see  fig.  1Ï2). 
Here  we  may  r«-niark  that  by  a  homogeneous  clot  is  meant  one  in  which 
the  hbrinous  reticulum  incloses  red  and  wbitc  blood  corpuaclca  scattered 
evenly  throughout  the  entire  extent. 

Uitulflei.'ieb  stjiteit  that  the  moiit  convenient  method  of  pre|iknii|g  a 
1ijçate<l  artery  for  microacopic  study,  is  by  making  thin  sectlona  tnuw* 
verse  to  the  axi;»  of  the  vessel.  Oar  experience  leads  us  to  prefer,  in 
the  main,  sections  longitudinal  to  the  a\is  of  the  artery,  alùiough  in 
every  case  transverse  sections  should  also  be  examined.  It  is  perhaps 
from  exclusive  examinations  of  one  or  two  cross  sections  which  passed 
through  the  upper  part  of  the  blood  clot,  that  KindHeisch  bas  formed  his 
erroneous  conclusions  concerning  the  structure  and  tbo  formation  of  the 
arterial  thrombus  after  HgutuR-.  Otherwise  it  is  difficult  to  understand 
how  such  an  experienced  microscopist  could  so  conipU-tely  fail  to  recognixe 
the  varied  constitution  of  the  arterial  plug,  which  in  fifty  or  «xty  ob. 
eervatioiis  wo  found  to  be  nearly  constant.  (Only  in  one  or  two  instances 
was  the  clot  homogeneous,  and  in  these  cases,  even  after  the  lapse  of 
some  <tays,  there  was  not  the  slightest  indication  of  a  reparatory  process 
at  work.)  leaving  for  a  moment  this  curiously  constructed  blood  coagu- 
lum,  which  for  the  sake  of  distinction  we  term  the  fibritwua  dot,  let  us 
turn  our  attention  to  other  objects. 

So  soon  as  the  ligature  is  tied  and  the  liquor  sanguinis  in  the  Ugated 
Teasel  is  nearly  in  a  stale  of  stasis,  the  element»  of  tbo  tunica  intima 
begin  to  increase  in  number.  The  lining  endothelium  and  th«  subjacent 
cellular  elements  very  soon  present  the  appearances  of  an  acute  cnilsr-

nu»  of  colorless  elements  fortnin»  the  swollen  and  inSamed  tunica 
intima,  by  meat»  of  filament*  of  fibrin.  Similar  fibrinous  filaments  also

(«ee  fijt.  17<>t;  itomviime*  the  fibrinou»  dot  is  firmly  attached  on  all  sides. 

The  swollen  and  iiillnniod  tuiiiat  intimn  mifjht  be  conwdcrtnl  as  a  cu]>, 
within  which  the  blood  clot  is  (ilnccil,  and  to  which  the  latter  \»  attached

the  pl'Utir  efot  (  p,  fi;^.  1TU>.  Dissociation  with  needles  and  flul*ei|uent 
staining  with  .carmine  show  that  the  mass  of  the  plastic  clot  is  composed 
almost  entirely  of  large,  grantitar,  uni-  or  multinucleated  memhranele^s 
cells  of  various  forms,  mainly  due  to  reciprocal  pressure.  Tbey  arc 
nsnally  flattened  and  more  or  less  endothelial  in  appearance  (see  fig. 
17^).  Among  these  larf^e  firanulnr  endothelioid  elements  are  a  con- 
Kderable  number  of  lymphoid  c<>ltfl  and  a  few  red  blood  corpuscles. 
Tbew  clemenu  are  hchi  l<>s»'tlicr  more  or  lews  firmly  by  an  intercclltilar 
»u)HtUi)c«,  which  \a  sometimes  stmctureleM,  sometimes  grunular,  and  ocoa- 
Monally  sii^hiiy  filirillar  (li;;  171). 

Jn  a  few  days  the  walls  of  this  mass  forming  the  plastic  clot  hepn  to 
bud  and  put  fortli  granulaûons,  which  soon  till  the  spaces  orijtînally 
kft  between  the  blood  clot  and  the  walls  of  the  cup  in  which  it  is  lodged. 
A  little  later  still,  these  granulations  have  increased  to  such  an  extent 
that  tbcy  must  bave  room.  The  space  required  for  their  growth  is  fin-, 
nislieii  at  (he  expense  of  the  blood  clot.  If  the  latter  is  cmly  feebly 
UUdied  at  the  tiides,  die  lalvrni  filament»  of  fibrin  which  form  the 
Éttschmenta  are  torn  loose,  ami  the  blood  congulnm  is  uplifu-d  bodily  and 
ptuhed  before  the  growing  plastic  formation. 

In  this  case,  but  little  alteration  is  seen  in  the  fibrinous  clot  for  a  long 
time.  Kren  at  the  end  of  twenty-five  days  there  is  no  sign  of  organi- 
tation.  (See  fig.  17.Î.)  If,  on  the  other  hand,  the  fibrinous  clot  he  fimdy 
bound  to  the  walls  of  the  vessel,  the  granulations  from  the  tunica  intima 
invade  the  cracks  and  crevices  of  the  blood  clot.  The  latter  gradually 
softens  and  wears  away  through  the  pressure  and  absorbent  power  of  the 
enlarging  gramilations,  and  after  twenty  or  twenty-five  days  there  ia 
often  ■>»  trace  of  its  presence  except  sonic  accumulations  of  pigmentwid 
hUy  granules  between  and  u])on  the  granulations.  These  granulations 
have  much  the  same  structure  us  those  upon  the  surface  of  orilinarj 
granulation  tiftiK.  They  are  o<ivt!red  by  a  layer  of  endothelial  cells, 
8ucb  as  line<i  the  surface  of  arteries.  Their  base  is  up>n  the  elastic 
lamina  of  the  tunica  intima  which,  up  to  the  twentieth  or  twenty-fifth 
day,  ia  still  ]jerfectly  distinct,  forming  a  sliarp  boundary  between  the  mid. 
die  coal  of  the  artery  and  the  prolil'erstiou  of  the  inner  tunic,  {e.  Fig.

that,  in  these  caDcs,  the  coagulation  of  the  blood  has  folloned  the  oburuc- 
tion  of  the  artery. 

In  wonnds,  ulcers,  and  chronic  nhlepnons  it  is  frequently  «en,  in 
sections  made  for  microscopic  examination,  that  the  internal  coat  of  the 
arteries  ha*  swollen  so  as  to  eoniplctely.obstruct  the  calibre  of  (he  vessel. 
There  may  form  in  these  elevations  vascular  networks,  so  that,  at  soma 
point»,  the  Kame  apji'tarances  arc  presented  which  have  been  de«cribed 
in  connection  with  the  lij;ation  of  arteries. 

In  the  .*raaU  arterie.*  there  is  another  cause  for  the  coagulation  of  the 
blowl  which  is  very  important  ;  it  ia  the  arrest  "f  the  circulation  in  the 
'Cnpillary  vessels.  When  in  conïte<{uence  of  an  interstitial  suppuration, 
of  a  catarrhal  inHammattan  of  the  lunj:;,  or  of  an  intt^i^titial  hemorrhage, 
the  blood  is  arrested  in  the  capillaries  by  the  pressure  of  the  morbid 
product  and  is  coagulated,  the  coa^uhmi  extends  backward  into  tlie 
arteriole  to  a  point  corresponding  to  where  the  circulation  is  effected 
by  a  collateral  vessel.  An  arteritis  occurs  at  the  point  of  coagulation, 
and  may  be  th«  origin  of  a  rupture  of  the  vessel  and  a  hemorrhage,

b«com«8  an  emfi^JuM,  and  cauaea  arterial  obatruction  hj  embolism.  In 
this  example  it  is  easy  to  follovf  tlie  most  important  phases  of  cmboUsm,

and  ;;rout  hindrance  to  the  |iitln>onary  circulnlion  caiisinj;  ntpid  death. 
At  the  mitopey,  there  is  found  in  a  branch  of  the  pulmonary  artery  a 
clot  which  hait  cortaiidy  not  been  fonned  at  thi«  point,  for  it  prcoent»  an 
outline  entirely  different  in  shape  and  diameter  from  that  of  the  obstructed 
artery.  The  olwtruoting  clot  is  whiuitli  or  yellowish  in  color,  it  may  be 
foliled  upon  iMelf,  an<l  have  branches  which  do  not  correiipond  to  the 
nimificatioim  of  the  pidinonary  artery.  Fre<|»ently  it  ia  surrounded  by 
a  recently  formed  cruoric  maaa  ;  but  aa  t>iis  recent  clot  liaa  much  lean 
eonsbUmce  than  the  embolua,  and  as  there  is  not  a  firm  adhciion,  it 
may  be  easily  separated  from  the  old  cloi,  when  it  will  bo  seen  that  the 
embolus  had  the  form  and  calibre  of  the  vein  in  which  it  waa  nrimnrily 
contained.  Such  is  the  simplest  and  mo«t  easily  veriGcd  caae;  out  when 
tfav  (oigratini;  ctot  ie  very  email,  or  when  it  is  reduced  to  very  amiill 
pieces,  and  tnmspnrted  by  the  ciroulalion,  it  it  ofl*n  impossibUt  to  find 
tlie  embolua,  the  exi!«tcncc  of  which  is  supposed  only  from  the  lesions  and 

*tfae  symptoms. 
Thia  theory  of  embolism  has  been  employed  without  sufficient  evidence 
to  explain  a  series  of  analouiical  changes,  such  as  the  alwcessea  of  puru. 
lent  infection  and  puerperal  fever,  in  which  the  existence  of  migrating 
dote  hare  not  been  dcmonatrated.  It  is  not  enough  that  the  blood 
may  coa};ulate  and  the  circulation  stop  in  the  arteries  of  the  focus,  in 
onler  to  bo  able  to  aRirm  thstt  then-  has  been  an  embotuSi     Indeed,  as 

•  before  mentioned,  evory  interstitial  hemorrhage,  and  some  inflammations, 
eause  an  arrest  of  circulitiion  in  the  capîlhiries  and  consequcntW  arterial 
thrombosis.  Virehow,  by  employing  the  word  mfarrtun  in  order  to  dc- 
Bignale  certain  le^iona  following  einbdiitni,  ha.-«  helped  to  throw  great 
obscurity  upon  tliia  cjuestion.  Itefore  Viivhow,  tlii.i  word  wn#  applied  to 
a  aeries  of  indefinite  changes,  in  particular  to  ]iai-enchyniaii>n!<  hemor- 
rhages. Laennec  called  the  foci  of  pulmonary  aitoplexy,  hemorrhagic 
infarcti.  îïince  then  the  doctrine  of  embolism  has  been  generalised,  and 
thor»  has  been  a  tendency  in  science  to  connect  with  embolism  everything 
the  older  writers  called  infarctus.  It  ia  incontestable  that  a  certain  nnm- 
ber  of  infarcti  have  an  embolus  for  their  origin,  aa  in  the  kidney,  spleen, 
liver,  etc.,  when  there  are  Been  white,  yellowish,  anicmic  foci,  having  the 
shape  of  a  comi  with  the  hnse  turned  towards  the  surface  of  the  organ,  and 
which  represent  the  di^tribiilion  of  an  arteriolt;.  At  fir^t  it  would  seem 
that  this  ti^^ue  diit'ered  very  much  from  that  of  the  organ  affected,  but  by

The  tieipielnei  of  embolism  in  the  artoriea  of  the  extremitjefl  and  a!!  the

coloring  subst&itce  in  the  form  of  pigment.  The  pfuvnchymatous  «ellukr 
elements  undergo  fatty  degeneration:  the  infarctus  now  becomes  yeb 
lowish-white;  it  still  retains  a  firm  consistence,  and  contnicting  a  little  is 
somewhat  smaller  than  the  red  infarctus.  This  yellow  infarctus  consista 
of  a  iiuwii  within  the  organs  tso  distinct,  that  it  couM  be  mislakeii  for  a 
tumor  if  it  were  not  cotie-shapfrd,  with  the  base  tumeil  tnwanU  the  [le-

reveaU  the  texture  of  the  organ:  the  vcRseU  are  found  injected  with  a 
granular  mass  due  to  a  transformation  of  tlie  blood,  and  the  parcnchy- 
Eoatoua  celts  of  the  organ  are  infîltraied  with  falty  granules. 

At  the  margin  of  the  white  infarctus  the  vessels  of  the  living  part  are 
dilated  and  filled  with  blood;  the  connective  tissue  is  infiltra^d  with 
white  corpuscles;  frcrjuently  in  this  portion  there  are  found  interstitial 
hemorrhages  ^'arying  in  extent.  The  parenchymatous  elements,  the 
epithelial  cell»  of  the  uriniferons  tubules,  or  the  hepatic  cells  for  example, 
present  mulli|>le  nuclei  ami  at  times  fatty  ileg<'nerJition.  In  the  kidney  the 
tubules  contain  fibrinous  oa«ts,  blood,  and  sometiincs  white  corpuscles. 

In  tlie  thti\l  stage  the  white  infarctuA  is  softened  ;  the  Aoftening  hegina 
at  diecentre,  as  a  result  of  molecular  destruction  of  all  the  necrosed  parta. 
This  molecular  detritus  is  then  t.iken  up  by  the  lymphatics  of  the  con- 
nective tissue  whicii  acta  as  a  cyst  wall  around  the  dead  part.  This 
occurrence  is  very  much  like  that  described  as  taking  place  in  caseous 
gummata.    (Sec  pp.  Ill,  Hi.) 

Sometimes  the  soft<-ned  infaivtus  is  infiltrated  with  calcareous  granules

feR'd  with,  and  upon  the  nature  of  the  emhohiA  which  oaosed  tlie  infan;- 
tion.  If  tht-  infarct  is  xmall  awl  tho  embolus  pottemes  no  infeclit'e 
properties,  the  ooagulaled  blood  may  gradually  become  decoloriited,  and 
tlic  mass  undei^o  a  gradual  process  of  absorption.  The  infarct  tlien 
changes  from  a  dark  red  to  a  brown  or  yellow  lint,  its  more  external 
portions  becoming  organized  into  connective  dasuc.  and  the  whole  gnul- 
ually  contracts,  until  ultimately  a  cicatrix  may  be  all  that  remains  to  indi- 
cate the  change.  If.  however,  the  infarction  is  considerable,  the  moloc» 
alar  disintegration  jiuit  Koft<:iiing  may  be  so  extensive  e.s  to  convert  ths' 
mass  into  a  pulpy  grunuliir  material.  This  may  «ubsoquently  dry  up  and 
become  encapsuled.  In  ull  these  secondary  changes  which  take  plocc  in 
the  infarct,  it«  most  external  ])ortions  arc  «urrouudcd  by  a  red  lone  of 
hyiwriemiu  tiwuu.     This  is  exceedingly  characteristic. 

If  an  emt)o!u^  poi<sesses  irritating  or  infective  properlie«,  as  when  it  is 
derived  from  a  part  where  putrefactive  inflammatory  changes  are  going 
on,  it  sets  up  inflammatory  processes  botii  in  the  vessel  within  which  it 
becomes  impacted,  and  also  in  the  surrounding  tissues.  These  inflam- 
matory changes  fre<|Uently  lead  to  the  formation  of  absoessca,  whieh  are 
known  as  emb-iUc  abscegae».  The  formation  of  such  abacoues  nuy 
oaaociated  with  more  or  less  infarction  of  the  embolic  area.

In  a  very  advanced  Ata^e  of  thi.t  nietamnrphoaia  the  muscular  cells  are 
fused  into  a  single  ma-ss,  and  the  wall  of  tlio  arterjr  seems  to  bo  consti*

is  lessened,  and  this  may  be  to  such  an  extent  as  to  arrest  the  circulatioa* 
of  the  blood. 

The   organs   most   froquently   the   scat  of  amyloid  degeneration  of 
arteries  are  the  spleen,  Hvor,  kidney,  mucous  membrane  of  the  intestines, 
and  the  lyinplialiu  glandn.    This  arterial  1e-«iou  which  is  associated  iritfa^ 
a  similar  tranciformation  of  the  parenchymatous  cell»  of  these  organs,  is  aj 
consef|uence  of  prolonged  suppuration,  of  phthisis,  of  syphilis,  etc.  I 

Tt!M0K3  OP  Tlis  Aktkkies. — Primary  tumors  of  the  arterial  system 
consist  of  a  new  formation  of  arterial  tissue  as  seen  in  dilatations  aud 
elongations  of  arteries  in  situple  angiomatn  (see  p.  llti)),  and  in  u  pecu- 
liar essentially  arterial  form  of  angioma — the  arterial  varice.»  or  varieosO  J 
anciirisiTi.  In  these  tumom  the  arteries  are  dilated,  elongated,  Uirl(ioti*,1 
and  thickened;  they  present  mimerou»  anastomoses  and  partial  ililatA- 
tion*.  They  are  most  frequently  located  on  the  temporal  and  occi[HUl 
arteries. 

The  arteries  which  are  connected  with  iiome  tumors,  for  example  in  the  J 
breast,  thyroid  body,  etc..  are  extremely  hypertrophied,  and  there  ofteo^ 
occurs  a  true  new  formation  of  arteries  at  the  same  time  that  the  tUDMr 
grows.  This  new  formation  appears  to  take  place  by  a  transformation 
of  the  capillaries  into  arterioles  and  larger  arteries  by  the  formabon  of 
smooth  muscular  elements  developed  from  the  embryonic  cells  surround- 
ing the  vessel.  Iloirewr.  this  evolution  is  very  difficult  to  follow,  and

tions,  or  by  bemorrhagee  which  occur  on  account  of  the  weakness  of  the 
walls  of  the  vessel. 

These  lesions  are  obseired  especially  in  sarcomata  and  carcinotnata 
of  rapid  development  ;  the  tissue  of  the  tumor  is  seen  to  grow  into  the 
vessel  after  the  middle  coat  bas  disappeared.  When  the  circulation  is 
impeded  or  iatemipted  hy  these  lesions  of  the  arteries,  the  parts  sup- 
plied by  them  mortify  ;  if  the  mortified  portion  is  superficial,  as  ia  the 
case  in  tumors  of  the  neck  of  the  uterus,  there  is  softening  and  ulceration. 
If  the  necrosed  mass  is  deeply  situated  in  an  organ,  it  gives  rise  to  a 
caseous  focus. 

Tuberculous  granulations  are  very  often  developed  in  the  tunica  ad- 
ventitia  of  arterioles.  The  result  ia  the  obstruction  of  the  small  artery 
and  a  coagulation  of  the  blood  in  its  interior.

contained  in  tliia  tisaue  is  separated  from  the  blood 
by  two  layers,  the  cellular  membrane  of  the  capil-

In  the  (glands  the  capillaries  which  arc  found  iu

Tlie  inllummatory  phenomena  present  in 
the  capillaries  i-oii.>ti.ti  in  a  modification  of 
their  whIIk,  and  in  the  formation  of  new 
capillary  vessels,  which  always  take  their 
origin  from  the  old. 

There  ia  first  observed  in  the  capillaries 
a  swelling  of  the  cells  and  their  nuclei  ;  the 
cells  which  were  flat,  homogeneous,  and 
could  not  be  distinguished,  now  appear 
granular,  and  when  viewed  in  profile  are 
fusiform  and  distinct  one  from  the  other. 
This  arrangement  is  capi-cially  appreciable  (,_.

It  may  occnr  in  all  organs,  but  U  especially  common  Id  the  kidney  and

eally  the  capillaries  of  the  brain  of  aduluj 
freijuently  contain  a  few  scattered  refract-

capillaries  are  loaded  with  fatty  granules, 
which  at  some  pointa  give  to  the  caiiiliary 
the  fonn  i>f  a  dark  grnnidar  cylinder. 
The  lymph  shciith  at  this  time  contains 
blood  and  granules  uf  ha'inatoidin  (Gg.

In  injuries  of  the  veins,  the  coa;;ulation  of  the  blood  and  the  phlebitis 
occur  at  the  same  time,  so  that  in  these  ease*  the  phlebitis  is  at  least  in 
part  dependent  upon  the  thrombosis. 

AVIten  a  lîf;ature  is  applied  to  a  vein,  an  operation  almost  entirely 
«bkiidonod  in  surreal  ])ractice,  the  blood  coa;;iilat«)i  in  the  peripherat  end 
a«  far  as  the  ftntl  collateral  bmnch  ;  there  i#  also  a  clot  formed  in  tlie  cen- 
tral fnd.  During  the  liwt  few  day»  there  a  ob«ervod  only  Kwelling  «ml

well  marked  at  tlic  place  of  the  lî^taturc.  Later  the  elevaliouii  liecoiae 
vascular,  unite  together  and  obliteration  of  the  vein  takes  place  aa  in  arte- 
ries. The  clot  does  not  appear  to  bo  organized  in  the  veins  any  raoro 
than  in  the  arteries;  it  undergoes  a  granular  change  and  gradually  dis- 
appears. 

rill."  simplest  wound  of  a  vein  is  that  occurring  from  the  operation  of 
lilecdiii^  at  the  bci»l  of  the  arm,  includin<;  the  vein  and  i>ikin  ;  it  hcnls 
by  tlie  fintt  intention.  As  previously  describcl,  this  mode  of  heiilin^  is 
not  ai'compliiiheil  without  inflammation  playing  au  tmpctrtant  role.  A 
tliiii  clot  remains  between  the  lip^  of  the  wound  ;  the  following  day  tliere 
LI  «een  a  redness  ami  slij;hl  œdeiiiali^u-t  swelling  of  the  skin;  ahtinl  the 
fourth  day  the  scab  which  hatt  formed  upon  the  incision  fatU  off,  and  the 
cicatrix  ia  completed.  The  bistolotry  of  these  simple  phenomena  has 
not  yet  been  studied,  but  it  is  probable  that  the  union  of  the  rein  takes 

fJaco  as  in  connective  tissue  of  the  skin,  by  the  interposition,  between  the 
ipe  of  tlie  wound,  of  an  embryonic  coancctlre  ^ssuo  and  its  orgauimion 
into  ordinary  connective  tissue.     (See  p[).  71,  2i2.) 

ttHicn  in  consenucTice  of  a  sup|>urutiiig  wound  or  of  a  phlegmon  located 
near  u  rein,  the  connective  tissue  of  tbo  external  coat  of  the  vein  juariiei- 
pate»  in  the  inflammation,  there  arc  seen  embryonic  celU  or  pu*  corpus- 
cles between  the  fawiculi  of  the  connective  tissue  of  this  coat.  The 
external,  mid'lle,  and  internal  ooatd  of  the  vein  may  ulcerate  and  ba  de- 
stroyed, by  means  of  the  same  process  which  causes  the  formation  of 
an  alirjcess  (softoning  and  necrosis').  This  is  observed  parûcularly  in 
a  phlegmon  of  the  a:icilla,  of  the  groin,  and  of  the  posterior  mediastinum  ; 
fre^iueiitly  the  ulceration  of  the  veins  i^  accompanied  with  a  coa;;ulaiion 
of  the  blood  in  the  interior  of  the  v-^sscl.  The  danger  of  a  diroct  intro- 
ilnetion  of  pus  into  the  circulatory  system  is  prevented  by  this  coagula- 
tion of  the  blood.  At  times,  however,  the  clot  does  not  completely  plug 
the  vessel,  and  then  septicn;mia  and  pyicniia  supervene;  agaîit  the  clot 
already  fonned  may  undergo  further  niodlfi cations,  it  may  soften  in  th« 
centre,  and  form  on  the  cardiac  sîdt.-  an  anfractuous  canal  which  connecta 
tlic  suppurative  inllauimatory  focus  with  the  vascular  system.     The  loss

process  in  tlieso  cases  bcin^  rapid,  organized  vegetations  upon  tUo  internal 
coikt  of  the  veins  are  not  found. 

In  woiinik  of  the  veins  such  as  occur  in  amputations,  all  the  hlood  be-

etidophlcbitiH  Hk«  that  wliioh  follows  a  ligature,  and  obliteration  of  liie 
vessel  is  tlie  result. 

From  the  preceding  description  it  iti  seen  that  coagulation  of  Uie  Mood 
accompauicR  pldebiti^;  until  a  few  yoara  past  it  was  believed  that  every 
coagulation  of  tlie  blood  in  tlio  veins  was  caused  by  tlio  pblelntifl.  V'ir- 
chow  endeavored  to  show  tliat  primary  phlebitis  is  extremely  rare,  and 
that  when  a  coagulation  is  seen  in  a  vein  witli  phlebitis,  tlic  coagulation 
bas  moi<t  frci|uently  preceded  the  tnllammutio».  This  Uieory.  which 
eeciat  to  119  too  poiMtivu,'  haa  however  been  accepted  hy  most  Oenn&o 
paihblogtstit. 

The  causes  of  venmiii  ffiromlifniit  are  of  two  kinds  :  a  slowing  or  arrest 
of  the  circulation,  or  changes  of  tlie  internal  coat  of  the  veins. 

After  death,  the  bloodwhieb  has  collected  in  the  vonouR  system  coagn- 
lates.  It  is  important  that  the  pathologist  should  be  able  to  recognize 
these  post-mortem  clots  in  onlcr  not  to  confound  them  with  those  of 
,  thrombosis.  They  are  met  with  eiçpccîally  in  the  large  veins,  in  the 
v«na  cava,  ilîue  and  fcnioml.  These  po^t-niortvm  clots  occupy  onlv  a 
small  part  of  the  calibre  of  the  vewel,  never  filling  them  eomplelely; 
they  do  not  adhere  to  the  wall,  and  after  opening  the  vein  and  removing 
thv  coagnlum,  it  is  found  that  prolongations  have  entered  the  «ollalenil 
branches.  These  clots  are  red-hrowu  streaked  with  yellowish-white,  or 
an?  in  part  fibrinous  and  eruoric;  the  whitish  or  pink  portion  is  seen 
always  in  the  superior  layer,  the  rod  in  the  inferior  dependent  («rt 
according  to  the  position  of  the  cadaver.  In  the  same  vem  these  clots 
present  great  inciiuality  of  thickness,  duo  to  the  presence  of  ibe  valves 
and  tortuosities  of  the  vein.  They  have  the  consistence  of  fibrin  and 
may  be  toni  into  laminn;,  or  they  are  curdled.  The  latter  variety  are 
seen  especially  id  poisoning  by  phosphorus,  arsenic,  aod  in  infectious 
diseases. 

The  arrest  or  impediment  of  the  circulation  which  causes  thrombosis 
during  life  is  due  to  a  weakness  of  the  heart,  or  to  a  local  interference 
of  the  capillary  circulation  belonging  to  tlie  vein  which  becx>mes  tlie  seat 
of  the  thrombosis. 

Such,  for  example,  are  all  asystolic  cardiac  lesions  causing  the  forma-

same  in  leucocylbicmin  ;  the  capillary  circulation  bein^  interfered  with 
on  Kcconnt  of  the  ;;rcat  number  of  white  corpuscles,  clots  are  rca<tily

When  ni]  artery  \»  obstructed  by  an  embolus,  the  blood  is  arrested  in 
tlie  cnpiliaries;  it  docs  not  circulate  in  the  veins,  but  there  coa;;ulatcs. 
tiuoh  are  the  phenomena  alway»  tieen  in  embolic  tnfnrcti  of  tbc  liver, 
spleen,  kidneys,  nnd  embolic  gangrene  of  the  exiremiciiM. 

The  venouii  thronibtia  fitU  completely  the  calibre  of  the  resweU:  it  it 
adherent  to  the  wall  and  terminates  at  the  cardiac  end  in  a  j>oi»t  or 
groove.  It  is  formeil  by  a  series  of  layers  joined  together,  the  mast 
superficial  of  vrhich  arc  the  most  recent,  and  may  bo  still  cruonc,  wliile 
the  central  and  middle  layers  arc  gray  or  yellow.  When  the  dot  h  old, 
there  is  freiiucnlly  found  in  its  centre  an  anfractuous  cavity  filled  with  a 
pariform,  vrnit*  or  opai^ue  detritus. 

A  microMopc  examination  of  this  detritus  shows  numerous  white  cor- 
puscles which  hnve  cxperieiiccil  cationtion;  they  iirc  irregular,  present  in 
tlieir  interior  fatty  granules,  anil  do  nut  contain  any  apparent  nuclei. 
IJetiideii  tlie:je  corpiu-^cleii  are  found  granules,  which  diiiappear  by  the 
addition  of  acetic  acid,  and  free  fatty  granules.  A  section  of  the  clot 
shows  red  blood  corpuscles  at  the  peripheral  portion  of  the  thrombus, 
vbicb  can  be  siill  recogniaed,  senaratcd  by  rcticiduted  layers  of  fibrin, 
in  which  arc  seen  white  corpuscles.  In  the  interior  of  the  layers,  the 
fibrin  fonns  closer  laminie,  between  which  an.'  seen  granular  collections 
varying  in  siïo  and  shape,  containing  pigniciitAry  musseii. 

'fhcrc  arc  alwavs  in  the  thrombi  of  veini  numuroii»  white  corpuscles, 
n  phenomenon  which  cannot  b<i  attribntiil either  to  a  new  formation  or  to 
a  migration.  It  bus  been  seen  that  alway»  when  there  is  a  retardation 
of  the  circulation  of  the  blood  nt  any  p.irt  of  th«  vascular  system,  the 
white  corpuscles  arc  there  uccumulated.  i^ince  thrombosis  t-i  preceded 
by  a  retardation  of  the  blood  circulating  in  tlie  vein  which  is  the  seat  of 
the  lesion,  it  U  iialuml  thiU  the  blood  coagulating  under  this  condition 
should  contain  a  greater  number  of  white  corpuscles.  These  are  free 
in  the  centre  of  the  clot,  which  ia  the  oldest  part,  because  tlie  fibrin  there 
nndergoes  a  granular  change. 

Tb«  disposition  of  ibe  thrombus  into  concentric  layers  is  due  to  the 
primary  clot  being  formed  h\  the  blood  coagulating  in  a  body  in  the  vein 
and  undergoing  a  shrinking  by  the  contraction  of  the  fibrin.  There  thus 
is  formeii  a  space  between  the  clot  and  tlie  wall  of  the  rein,  which  is 
soon  filled  with  blood  which  circulates,  ulthough  slowly.  The  oMigula- 
uon  of  this  last  blood  is  followed  by  a  new  .shrinking,  and  these  phe- 
nomena are  continued  until  the  rein,  completely  distended,  is  ajiplied  so 
accurately  upon  the  clot  that  the  circulation  is  arrested.     Until  the  clot

word  vftricea  'n  not  absolutely  «ynonymous  with  phl«becla«cj,  for  simple 

[dilatation  or  nhlebectasiD  may  be  seen,  for  example,  around  tumors,  wi(b> 

[out  there  bein^  any  varices.     When  the  tumor  is  removed,  the  simply 

dilated  veins  retnni  «gain  to  their  primary  condition. 

Varices  are  observed  «specially  in  the  superficial  veins  of  the  inferior 
extremities.  In  order  to  see  the  arrangement  of  varicose  veins,  they 
«bonld  be  dissected  for  their  entire  extent,  when  it  is  found  that  they 
are  not  only  dilated,  hut  elongated,  and  fonn  numerous  curves.  The 
calibre  of  the  vein  is  very  irregular  ;  fusiform  or  «mpulla-Kke  dilatations 
are  seen.  Their  walls  are  not  uniform  in  thickness,  wldch  can  only  lie 
demonstrated  by  oj>cning  the  vein.  The  valves  are  found  to  be  insuSi- 
cient,  or  reduced  to  loops,  or  flattened  against  the  wall,  or  pArtiy  de- 
stroyed. There  is  frequently  noticed  at  the  position  of  the  valve*  a 
con»derable  thickening,  in  the  form  of  nodules.  The  internal  surface  of 
.  the  vein  presents  longitudinal  nrommencea  and  depressions,  which  aj)[K>ar 
'  as  iorgitudinal  foM*.  The  wall  of  the  vein  is  in  plaoe«  extremely  iJiiok, 
so  that,  in  transverse  suctions,  tig  calibre  remains  gaping  like  that  of  an

muAcular  fawiouli  of  this  coat  which  are  theot*elve!i  hypertrophied. 

The  internal  coat  is  not  evidently  hypertrojihted,  and  usuallv  does  not 
present  végétations  upon  itA  fiurface,  unles-i  it  in  at  the  position  of  the 
valves,  or  when  there  is  a  thrombiti.  In  section  this  coat  appears  as  a 
bond,  which  colors  slightly  by  carmine,  and  possesses  two  or  three  rows 
of  lenticular  nuclei. 

Beneatii  this  layer  there  osists  an  elastic  network,  tlio  meshes  of 

lioh  are  formed  by  largo  fascicidi  of  connective  tissue,  generally 
a  lonptudinal  direction.  It  is  these  which  cause  the  longitudinal 
upon  the  internal  surface  of  the  vi-in,  visible  to  the  nnaiiled  eye. 
!?e  ra^etciilî  are  eovert'd  with  large  connective-tisaue  eella. 

Nc.\t  to  this  internal  layer  of  the  middle  coat,  the  thickness  of  which 
is  always  considerable,  come  faMicuU  of  muscular  fibres,  which,  when 
cut  transvet^ly,  appear  under  the  microscope  as  a  series  of  clear 
circles  presenting  in  their  centre  the  section  of  a  cylindrical  nuclotis. 
The  Iur<;e><t  of  the  muscular  fasciculi  are  elliptical.  Those  at  the  uK>ist 
exteniui  part  of  the  middle  cent  almost  always  are  circular  in  direc- 
tion, and  nm  at  right  antics  with  the  longitudinal  fawciciiti.  These 
fasciculi  are  ^parated  one  from  the  other  by  connective  tissue,  »o  that 
there  is  a  continuity  of  connective  tissue  from  the  internal  »  the  ex- 
ternal coat,  from  such  an  arrangement  of  structure,  it  follows  that 
the  muscular  elements  may  he  easily  separated  one  from  the  other,  and 
that  Huids  can  penetrate  into  or  exude  from  the  vessel,  which  explains 
the  frc>|uency  of  «deraa  and  chronic  iiitlammadon  in  these  cases. 

Between  ttio  fasciculi  of  connective  tissue  there  are  frequently  found 
granules,  or  collections  of  granules,  of  a  beautiful  yellow  color.  They 
are  composed  of  blood  pigment,  and  demonstrate  that  the  red  corpuscles 
of  the  blomi  have  infiltrated  this  tissue.  The  thickness  of  the  middle 
coal,  changed  in  this  manner,  is  two  or  three  times  greater  than  normal. 

TIte  dilatation  is  not  confined  to  the  principal  vein,  but  exieu'U  to  all 
its  branches,  and  especially  to  the  vam  V'im"ritiii  of  the  venous  walls. 
The  latter  are  much  dilated,  sinuous,  and  their  walU  are  ihicVened.  In 
Bone  cases  «here  the  dilatation  is  more  decideil,  a  vci-nel  of  considerable 
diameter  is  seen  in  the  midst  of  the  middle  coat,  and  may  often  extend

iH'Condarv  tumors  of  veins  occur  frequently.  Often  when  a  vein  Is 
surrounded  hy  a  malignant  tumor,  carcinoma  or  sarcoma  for  example,  iu 
walls  arc  coiiverled  into  morbid  tissue  which  sends  vascular  elevations 
into  the  calibre  of  the  vessel.  These  elevations  occasion  an  impedîmeot 
to  the  circulation  anda  coagulation  of  the  blood,  when  they  are  found  en- 
veloped within  a  clot.  Portion»  of  the  elevation»  may  be  deUiched  and  fonu 
emboli.  It  is  very  probable  that  the  geiiëralixation  of  certain  Narcomala, 
especially  encephaloid  sarcoma,  occurt*  hy  the  tr)ini«[ioi'talion  of  fragments 
of  this  nature.  Tho  fragments  of  morbid  ti.-wiie,  carried  away  by  the 
circulatin;^  current,  are  engrafted  in  the  diiferent  or):ans,  particularly  in 
the  lun^s.  and  become  the  origin  of  secondary  formations.

One  of  the  most  intere*tin»  anH  most  disputed  <iue3tionfl  is  the  origin 

tiie  lymphatic  ve.'<^el.4  in  the  tiiinne».     When  they  were  fltitdieil  hy 

HH  of  mercury  injeetions,  it  wa«i  believed  that  tho  reticulum  thuit 

"^hjecteit  naH  the  only  origin  of  the  lyin|)hatic  system.     Uut  since  tluidu 

which  are  much  more  penetrating!;  have  been  employed  for  iujecliug,  it 

h&B  been  found  that  ft  sroat  number  of  vpsjcIb,  not  injected   by  the 

»  mercury,  arc  rendered  viiible  by  these  fluid*.  It  is  only  necessary  to 
iBso  a  hypodemiic  syringe,  introduced  into  the  connective  tissue,  to 
demonstrate  that  the  lymphatic  vessels  communicate  directly  with  the 
iTrnjih  splices  of  the  connective-lisstie  system  «f  the  body,  (tiec  fig.  10.) 
L  it  has  been  *een  how  the  serous  cavities  arc  apfiendage^  of  the  lymjdiatio 
F  tyslem,  inasmuch  as  there  exista  a  direct  communicadon  between  these 
cavities.  The  lymphatic  ve-ssels  of  the  «erous  cavities  are  situated  very 
SuperBctalty  under  the  endothelium,  so  that  any  pathological  change  of  the 
serous  memhrsiieà  cannot  occur  without  tho  corresponding  lymphalicd 
experioncin;;  at  the  same  time  an  alteration. 

Lymphatic  vessels  forming  a  reiicuhim  are  always  foimd  around 
arteries;  in  many  organs  this  reticuhim  is  very  extensive.  The  spaces 
of  this  network  arc  in  conmi  uni  cation  with  a  lymphatic  sac,  which  partly 
surrotinds  the  artery  as  an  imperfect  fthenth.  The  lymphatic  sacs  are 
then  C(piivalent  to  a  peri-arterial  retieutiim.  This  arrangement  of  peri- 
'  vascular  lymph  sheaths  was  fintt  observed  by  Oh.  Itobin,  iu  the  arteries 
of  the  brain.

it  is  thus  seen  that  the  kI&ikIs  corre  spoiling  to  the  lymphatic  vessels 
communicating  with  the  pigmented  region,  are  twice  the  sise  of  the  same 
glands  on  the  opposite  side  of  the  body. 

A  few  of  tho  pigmcntated  glands  arc  hanl,  and  present  a  dry,  glisten-

The  reticulated  fibres  of  the  cavernous  system  are  hypertrophied  ; 
their  endothelial  cells  contain  Kramiles  of  pigment  ;  the  lymph  cells  also

be  BiirrouLided  by  a  layer  of  pus. 

In  the  ginnd  iteelf  are  found  altorationa  which  vary  according  to  the 
Stage  of  the  inflanimalian.  In  the  first  ppriod.  there  w  congestive  and 
influniniatory  ccdetna.  particularly  well  marked  in  the  cavernous  lynipliatic 
system,  so  that  the  follicles  and  fotlicnlar  cords  are  much  more  distinct 
tban  usual,  on  account  of  their  forming  whitish,  Ofia<|u«  apots  or  lûtes 
upon  a  slightly  translucent  ground. 

In  a  few  cases,  the  hygiertemia  and  extr.^t'asatinns  which  accompany 
the  tnDammaiion  occasion  an  increase  in  sixe,  and  a  red  or  red-brown 
coloration  of  the  whole  parenchyma  of  the  gland,  resemblinjç  tlie  tissue  of 
the  spleen.  Such  is  the  lesion  generally  seen  in  the  bronchial  glands  in 
pneumonia,  or  intense  capillary  bronchitis. 

At  a  more  advanced  period,  the  distinction  between  the  two  systems 
of  the  gland  is  not  apparent,  and,  by  scraping  the  cut  surface,  a  very 
abundant  juice  is  obtained,  as  in  soft  carcinoma.  In  a  normal  gland, 
twenty-four  hours  after  death,  it  contains  a  slightly  milky  juice,  analo- 
^us  to  that  obtained  from  an  cnccphaloid  sarouin.  Hut,  in  the  ca»  of 
inflammation,  the  juice  is  much  mure  abundant  and  more  milky. 

Under  the  microscope,  this  juice  in  inllaminatinn  presents  numerous 
lymph  cell*  and  large  endothelial  cells,  containing  one  or  more  nuclei- 
The  latter  cells  are  swollon,  and  resemble  the  mitltinucleateil  cells  of 
the  bono  marrow  (giant  cells)  ;  yet  they  are  not  so  numerous,  and  they 
contain  fewer  nuclei  than  those  found  in  certain  forms  of  a  chronic  nature, 
which  will  be  studied  later. 

InHammatioD  of  a  lymph  gland  may  continue  until  small  purulent 
points  are  formed  in  its  iiiteritjr,  or  a  single  purulent  focus  is  prodnced.

geneouii  snhAtance,  they  are  seen  to  be  constituted  by  a  fibrillar  and 
granular  material.  The  fibres  hare  reached  five  or  six  timed  their 
normal  diameter. 

In  th«  follicular  substance  the  fibres  are  less  swollen  and  doBot  exhibit 
a  fibrillar  structure  ;  they  are  simply  strewn  with  granules. 

When  the  inflamed  lymph  ;;lrtnd  rcscmblos  tho  spleen  in  color,  the 
capillaries  of  ihefollicularHyMU'mare  very  much  dilated  and  filled  with  red 
Mood  corpuscles,  and  helwiN'u  the  lymph  elements  which  fill  the  meshes 
of  the  MrMoa  there  are  seen  small  collections  of  red  corpuscles,  or  red 
conkiisoles  arc  disseminated  between  the  lymph  etemenU. 

If  the  adenitis  has  fipne  ou  Ut  suppuration,  there  are  «e«n  snail  col-

vhoso  lymphatic  radicles  have  their  ori-^in  in  an  inflammatory  focus, 
or  arc  in  eommumcation  with  an  ulceration.  It  is  very  probable  that 
the  inflammation  of  the  gland  is  then  <:oiincct«d  ttith  a  transportation  of 
irritating  sulwlances,  elaborated  in  the  infiammatory  foens  or  coming 
from  the  cxt^riiir.  I'neumonia,  bronchitis,  soft  chancre,  ulcerations, 
«specially  «f  the  inleittines  in  typhoid  fever,  etc.,  may  be  ciu-d  as  ex- 
amples of  iiil^amraations  which  cause  adcniliii.  Adenitis  is  also  seen  in 
infectiou-i  diseaseâ  (scarlatina,  âinalljKix,  etc.),  diseasei*  in  which  there 
are  verjr  probably  virulent  substances  carried  by  the  lymphatic  pa«-

FihmK  induration  of  lymph  glands  occurs  frequently  în  the  bron- 
chial and  inguinal  glands  of  persons  advanced  in  age.  uenerallv  it  ui 
accompanied  with  a  slight  hypertrophy  and  ingmentation  ;  it  consists  in

fibrouit  filaments  which  penetrate  into  its  interior.  The  calculus  is  fri-

waxy  jwrtions  are  oolored  by  piçnx'arniinatc  of  ammonia. 

When  fatcvii»  degeneration  supervene*,  there  frequently  remain  parts

or  leaa  perfect  ;  the  Bbrila  are  thinner  and  less  flexible  than  in  ihi'  norma!

TtlMOlt?. — Sarcoma  of  the  lymph  glands,  except  one  variety  which  has 
been  named  by  Billroth  adeno-iarcoma,  is  always  a  secondary  paihologi- 
cal  product.  It«  occurrence  is  not  so  frequent  as  carcinoma  and  opitho> 
lioma.  It  has  been  seen  that  carcinoma  and  epithelioma  are  propagated 
especially  by  the  lymphatic  paMsgcs,  while  sarcoma  is  gencraliBed  by 
the  bloodvessel  system.  This  is  due  to  the  circumstance  tnat  the  alvcoU 
of  the  earcinonia  are  connected  with  the  lymphatic  system,  while  on  tlie 
otlier  liandf  the  developniont  of  sarcoma  occasions  an  embryonic  trans-

of  the  primary  tumor.  u[>on  section.  F'ihrous  induration  of  lyinpli 
glands  always  precedes  the  formation  of  the  charactcrbtic  canceroiu  tis- 
ane, as  licsL-ribed  at  page  102.  The  histological  process  of  fibrous  in- 
duration is  very  simple.  All  the  fibrils  of  the  ri^'ticulum,  both  in  the 
cavernous  and  follicular  systems  of  the  gland,  are  hypertrophicd  in  such  a 
Dannor  that  the  nlvoolar  spaces  gradually  become  smuller  ;  a  few  ontir*'ly 
^disappear,  and  the  lymphatic  passages  of  the  gland  are  alnioitt  completely 
obliterated.  A  gland  so  altered  is,  for  a  certain  time,  a  barrier  to  th« 
propaf^tion  of  cancer,  .\  gland  which  ha»  experienced  thi»  primary 
fibrous  change,  later  presents  all  the  characlcnt  of  carcinoma,  and  be. 
comes  itself  a  new  centre  fi>r  the  infection.  When  secondary  carcinoma 
of  lymphatic  gland.i  is  rapidly  developed,  the  lymph  elements  included 
between  the  fibrils  of  tlie  reticulum  take  the  form  of  the  so-called  cancer 
celts,  while  the  fibrils  grailually  increase  in  thickness  in  order  to  form  the 
stroma  of  the  alveolar  tisiiue,  which  characterises  carcinoma.  (See

From  a  pencilled  section  of  a  lymph 
gland  aflfectfld  with  tubercle,  it  is  im- 
|)<>Milile  to  (UBen;;a;;e  the  stroma  from

iu  the  peripheral  layers  of  tlie  tubercle, 
ami  Aoinetinwi*  at  iliittnnt  [Kiints,  lar^ 
flat  celts,  containintt  numerous  nuclei. 
These  cells,  (Kiitited  out  by  t'oerster, 
and  afberwarda  by  many  other  writer», 
bave  been  considered  as  giant-celU. 
They  are  evidently  irrilaied  and 
swollen  endothelial  cells.  In  the  most 
central  portion  of  the  tuberculous  nodule  the  reticulated  stroma  bu  du- 
appeared,  the  lymph  cells  have  become  i;radunlly  smaller;  they  an 
muted  together  by  ft  now  intorccIlulAr  sulKttanccr,  »nd  fonn  nilh  it  ft 
eaaeona  mats  in  which  the  elements  cannot  be  di^liucily  reoj^uixed.  In 
the  centre  of  the  grautilalioii,  at  the  point  where  the  caaeou»  degenera- 
tion has  occurre<l,  the  celhdar  elements  become  free.  A  central  loss  of 
snbeiance  is  thua  occasioned,  'ilierefore,  we  cannot  understand  hoir 
Rindfleisch  has  been  able  to  maintain  that  the  tuberculous  granulation  is 
formed  of  raciculaled  connective  dasuc,  since  the  granulation  developed 
in  diis  tissue  begins  by  tranâforming  it.  In  the  tuberculous  granulation 
of  these  glands,  vessels  arc  found  varying  in  site,  according;  as  they  are 
located  in  the  cavernous  system  or  follicular  tissue  ;  Lhe^o  vessels  are  ob- 
structed by  a  fibrinous  congulum  or  by  white  blood  corpuscles. 

When  the  granulations  are  confiuenl,  all  portions  of  the  intertuedtary 
parenchyma  of  the  gland  undergo  citscous  i ran sfomia lion,  and  the  entire 
organ  may  be  alTeoted  and  assume  the  character  of  a  ^crofulou.*  gland. 
Id  many  ca$ea  tlie  differential  iliagnosis  between  a  tuberculous  gland  and 
a  »cmfulou8  gland  h  imfioijiible,  either  to  the  unaided  eye  or  with  the 
mîcro»co|ie.  But,  when  the  tuberculous  cvotutiou  is  rapi<t,  other  granu* 
lations  may  he  developed  alongside  of  the  caseous  mass,  so  that  the 
tuberculous  matter  can  be  distinguished  from  a  simple  caseous  dégénéra- 
don.

If  the  nervt's  involvt-d  in  a  wound  are  disuceu-d  witli  c»ro,  they  are 
found  .-«lijihlly  Hwollen,  and  upon  thuir  i^urfiwe  are  wen  red  liiM»  running 
longiluiliiinlly  which  indicate  the  congestion  existing  dnring  life.  'ïht 
nervt'S  in  wounds,  in  cases  of  tetanus,  have  been  principtly  exacniiied, 
and,  by  some,  it  bas  been  thought  that  their  congestion  was  the  cause  of 
the  convulsion.  Hut  this  Is  certainly  an  error,  since  congestion  may  bo 
observed  in  nerves  in  almost  all  wounds  where  tlierc  is  a  slightly  intente 
in  H  animation. 

In  coiigettion  of  nerves,  the  hyperiomia  can  l>c  rccognixed  with  great 
fadiity  in  the  peri-fasciuntar  vessels,  as  the  nerves  are  dii>tinct  from  the 
itnrnnindingparld.  llypcnemiaof  the  intra-fascicular  Te«éels  also  exists, 
but  it  is  not  always  easy  to  recognize  with  the  unaided  eye,  for  it  ii 
necessary  to  tear  tlie  laminated  sheath  in  order  to  aee  the  vesseU  filW 
with  blood.  To  judge  of  the  dilatation  of  the  capillaries,  transverse  cuta 
of  the  nerve  should  be  made, 

In  inflnramations  of  the  fingers,  the  nerves  present  a  congested  appear- 
ance, and  It  is  very  probable  that  intra -fascicular  hypenemia  of  the 
nerves  ia  an  important  cause  of  the  acute  pain  accompunyitig  these 
lesions. 

Congestion  of  nerves  occasions  an  increase  of  the  blood  pressure  and 
a  scrou.f  exiidatioii  into  lh«  peri-fiMcicular  oonnociive  tissue  ;  frvqiicntly 
niilinry  heninrrhages  are  also  produced.

C0Dae<(uenee  of  the  <)iviM»n  of  a  nerve.    The  opportunities  to  study  iheni 

I  in  man  are  rare,  although,  in  war,  wounds  of  the  nerves  are  common  ; 
bat  the  vroiinded  soon  die,  or  recover  and  experience  ft  aeries  of  symp-

txpcrimcnt. 

Some  uritPis,  Foeistor  aniong  othpre,  spenic  of  the  immédiate  imioD  of 
nerves.  Vury  probably  their  opinion  is  based  upon  men-  clinical  facts, 
«och  as  the  rnpiil  ro-e»tj>bli«hment  of  the  fii  net  ion  of  a  neire  after  divUion. 
Recently,  Arloin^  and  Tripier  have  explained  thi*  by  a  complementary 
Dervoits  action  exerted  by  the  recurrent  peripheral  hrancliea;  t^ey  have 
supported  their  interjiretation  by  direct  exjierimenl.t. 

In  animaU,  divinton  or  re.*ection  of  a  nerve  ii  never  followed  by  îmme- 
diate  union.  Therefore,  it  may  1»;  doubted  if  it  ever  takes  place  in  man. 
When  a  nerve  in  a»  animal  ha:*  been  divided,  the  peripheral  end 
undergoes  a  special  degeneration,  and  after  a  variable  time,  not  less 
tlian  three  months,  there  is  a  restoration  of  the  nerve  and  its  function. 
Tliere  i»  by  this  time  a  union  of  the  two  enfls  of  the  nerve,  by  a  pi-ocess 
which  ii«  not  included  in  any  of  the  methods  admitted  by  siir^-ons.  It 
lit  neither  immediate  nor  secondary  union,  but  A  special  hîsLolo^cal  evo- 
lution which  has  not  yet  been  definitely  dpteniiined. 

■  Four  day»  after  division,  in  a  mammifera,  the  [icripheral  end  of  the 
serve  has  loat  its  neurility,  and  from  thii*  time  ihe  de jçene ration  liefpns. 
When  a  nerve  is  destroyed  by  certain  processes,  its  |ihysîolojçical  pro- 
perties may  disappear  immediately,  and  the  defeneration  aUo  soon  fol- 
lows. Thus,  by  the  action  of  water  upon  a  portion  of  the  sciatic  nerve 
of  a  rabbit,  causing  its  destruction,  de;ieneracion  and  loss  of  neurility 
may  be  occa*ioned  in  about  foriy-eisht  hours. 

fhc  dejrenentiion  of  nerves  consists  essentially  in  a  se^cntation  of  the 

owdullary  stibrtance,  which  continues  until  re<;cncni^on  be^ns.     'Xliis 

H  legmentation  terminates  in  the  formation  of  fine  };ramdes,  which  lose  the 

Hdtaractera  of  medullary  substance  and  take  those  of  neutral  fat,  «ucb  as

found  in  the  or;^^ism.  Reduced  to  fine  fatty  graonlcs,  tUc  medullary

of  which  »n  not  yet  kDOwo.  From  eighteen  to  twenty-five  «lays  after 
die  division,  there  Btitl  remain,  in  tlio  nerve  fibres,  at  ci-rtaïn  points  along  j 
tlicir  course,  oblen;;  masses,  formed  of  vyVinderB  of  the  nH-dullary  suV^ 
stance,  n  few  myelin  drops  and  fatty  granules,  while  in  otlier  \»ni  of  the 
fibre  there  are  only  scattered  fatty  gronules.

traversin;;  llic  sheath  of  Schwann.  The  fatly  granules  become  free' 
among  tlic  nerve  fihrei*,  and  form  granular  corpiucle^  similar  to  those  met 
with  in  the  pcri^vawrular  lymjihatic  aheathii  of  tJie  brain  (corpuaclee  o£j 
Gluge),  in  simple  softening  or  liemorrha^^e  of  thiii  organ,  and  which  ara^ 
very  probably  lymph  corpTiscIe§  loaded  with  Catty  granules,  and  are 
again  taken  up  by  the  lymphatic  circulation. 

The  cells  forming  the  walls  of  the  intra-fascicular  vesaels  «bo  ooiltaia 
nnmerous  fatty  granules. 

In  about  twelve  to  eighteen  days,  when  the  wound  of  the  cellular  tis- 
sue and  intfgnment  is  united  by  the  first  intention,  the  two  ends  of  tliO  J 
divided  n«rve  are  joined  by  u  slightly  opnline  line  of  cicalrioial  liasooi^ 
which  proceeds  from  tlie  i>eri-fasoioular  ttsMie  of  the  superior  end,  to 
hk-ml  with  tlie  iwri-fascicwlnr  tissue  of  the  inferior  end.     The  easential 
pnrti  nf  the  nerve  an.i  not  yet  connected,  their  path  is  only  marked  out. 

A  microtwopic  examination  of  a  tran^ver^ne  section  of  the  peripheral  j 
end  of  a  nerve,  twenty-one  to  thirty  day»  after  the  operation,  présentai 
most  of  the  uervc  fibres  without  axis  cylimleri);  it  ]s  only  in  n  few  fibrca,  1 
the  diameters  of  which  are  considerable,  thnt  swollen  and  mispliiet-<l  a^ia  ; 
cylinders  arc  found.  Twenty-five  days  after  division,  the  nerve  fibres 
bave  therefore  lost  their  essential  element,  the  axis  cylinder. 

The  proximate  cause  for  the  degeneration  of  nerve  fibres  in  conse- 
quence  of  division,  i*  yet  unknown.     Wnller  taught  that  the  nutrition  j 
of  nerve»  depends  upon  ganglionic  celU,  which  tJirough  their  connection  | 
with  the  nerves  net  as  trophic  centres  ;   thus  the  nen,'os  degenerate  I 
when  they  are  separated  from  their  centres.     The  motor  roots  of  the  ' 
spinal  marrow  have  their  ti-ophic  centres  in  the  spinal  marrow  itself,  while 
the  posterior  roots  have  their  trophic  centre.i  in  the  spinal  ganglions. 
Thus  if  both  roots  of  a  nerve  are  divided  in  the  vertebral  canal,  tiie  peri- 
pheral end  of  the  anterior  root  and  the  spinal  end  of  the  posterior  root  j 
alone  experience  granular  dcgenemiion.     If  a  mixed  ncr\'o  is  divided  all 
it  passes  out  of  the  vcricbrnl  canal,  degeneration  occurs  in  all  parta^J 
which  have  been  separated  from  the  centre.     When  regeneration  lui*  00- ' 
curred.that  is,  from  the  third  to  the  fifth  month  iifterdivision,  the  peripheral 
end  exhibits  under  the  microscope  slender  nerve  fibre»  containing  normal 
medullary  substance,  alongside  of  degenerated  nerve  fibres  which  are 
not  coinplct^Oy  destroyed.     Waller  thinks  that  perfect  new   fibres  are 
formed  in  the  intrafascicular  connective  tissue  spaces,     SchitT,  Vulpian, 
Keiiiak,  etc.,  believe  that  it  is  the  previously  degenerated  fibres  which 
Oj^in  become  regenerated  and  assume  their  former  structure  and  function.

tlie  conseation  U  more  intense,  and  ma^  even  go  so  far  as  the  eflusion 
of  blood.  The  spots  are  rermilionred  m  color,  an  if  the  blood  contained 
in  ihfiir  vessela  was  highly  oxidized.  The  laminse  of  the  arachnoid  and 
the  pia  mater  so  changed  show  uniform  or  fusiform  dilations  of  the  blood- 
vessel», around  which  are  fret|uently  extruvasated  red  blood  corpuscles. 
The  choroid  plexus  is  found  to  be  congested,  as  is  also  the  vrfum  in^- 

The  tlitid  contained  in  tho  large  cavity  of  the  arachnoid,  in  the  ventri- 
cles, and  in  the  suharnchnoid  «pace.4,  i»  increased  in  ijuantily.  In  this 
fluid  numerous  cellular  element''  are  found,  large  granular  epitlielial  cells,

Whencei-ebral  rheumalism  baa  existed  for  twemy-four  hours  or  longer, 
tho  Huid  contained  in  the  arachnoid,  ventricles,  and  sub-arachnoid  spaced,

due  to  the  great  number  of  epithetia]  cells  aou  vhit«  blood  corpuacles 
which  it  now  contains. 

Tin;  conilition  is  not  peculiar  to  rheumatism,  it  may  be  met  wttb  in  all 
cerebral  congestions  acennipanicd  with  delirium,  vA  those  eauscd  by  pneu- 
monia,  variola,  typhnid  fever,  et«. 

Primary  r,-r>hrfil  mt-iiinyitif  is  extn^mely  rare;  it  may  be  caused  by 
insolation.  Inflammntion  extenditig  over  the  whole  surface  of  the  ner- 
vous centres,  or  curfhra-xpinnl  meningiti.t  \«  generally  endemic  and 
usually  occurs  in  armies  or  hospitals. 

The  inoHt  freiiuent  form  of  meningitis  is  that  which  followa  tubercuhMÎs 
of  the  meninges,  or  tumors  of  the  meninges  and  of  the  brain.  It  ifl

tticipTiinj;  and  opacity  of  the  connective  ti-tHuc  of  this  metnbnino.  an<l 
by  the  accumulation  of  paa  oorpusclea  aroumJ  anJ  along  the  vessels, 
where  the  connective  tissue  is  most  ahuititanl. 

nio  ve^seU  appear  to  the  unnided  eye  surrounded  by  an  opaaue  «me. 
Whi-n  Httidicd  with  the  microscope,  lymph  oorpusclea  arc  founa  located 
in  the  Inose  connective  tissue  siirroumling  thcin,  these  elements  besi<Ies 
aceiiTnnlale  in  tlie  lymphatic  sheath  of  the  vessels,  and  envelop  them  as 
n  cajBule. 

The  iU'ro-puruI<-nt  fluid  found  npon  the  surface  of  the  membnine  is 
someiinteit  very  thin,  aud  accumuhiU's  in  the  anterior  and  posterior  sub- 
arachnoitl  spaces,  or  it  may  he  tliick  and  mixed  willi  fibrin. 

When  the  meniugiti^  is  intense,  and  has  Instted  several  days,  the  pus 
mixed  with  fihrin  forma  under  tlie  visceral  arachnoid  a  continuous,  opa<|ue, 
yellow  layer,  thicker  in  the  sulci.  The  vessels  are  partly  imheddeil  in 
this  false  membrane,  an<l  are  seen  as  red  lines  covered  with  a  film.  From 
a  section  it  Is  found  that  tliia  fibrinous  layer  may  even  reach  five  mitlime- 
trcsinthickneesover  theaulci.  The  false  membrane  can  be  removed,  and 
the  firny  substance  beneath  is  seen  marked  with  red  points.  From  each 
red  point  one  of  the  vessels  which  penetrate  into  the  nerve  substance  has 
been  detached,  and  it  is  found  to  bo  surrounded  by  a  purulent  layer  and 
at  times  with  escaped  blood. 

In  cerebro-sjnnal  meningitis,  a  similar  exudation  is  found  around  t)ic 
^nal  marrow  and  poiiD.  The  pus  occupies  the  nracliuoid  cavity  of  the 
npinal  marrow  and  the  meshes  of  tlic  spinal  pia  mater;  but  it  docs  not 
peiwtrate  beneath  the  fibrous  part  t>f  tins  mcnibraac.  The  gray  sub- 
stance of  the  sjiinal  cord  presents  a  pink  color  to  the  naked  eye.  Slicro- 
Bcopic  examination  of  thin  sections  does  not  show  any  modifications  of 
the  nerve  elements,  only  a  simple  hypenemia  of  the  vessels  of  the  pi» 
mater,  and  a  few  pus  corptisclea  between  tlic  connective  tissue  fasciculi 
of  this  membrane,  f^ometimes  suppuration  is  so  rapid  that  the  amount  of 
pus  is  considerable,  even  when  the  symptoms  of  the  disease  have  existed 
oaly  a  few  houn. 

TuBKRCiii.nrs  StKXfxniTlP. — This  is  analogous  to  that  (iescribcd  muler 
purulent  exudation,  but  differs  from  it  by  the  presence  of  luherculou* 
granulations,  which  arc  generally  located  along  the  courae  of  the  vessel 
in  the  pia  mater. 

Frequently,  at  an  autopsy  of  meningitis,  it  is  thought  that  ^e  men- 
ingitis is  acute  and  primary,  because  evidence  of  granulations  are  not 
at  first  found.  It  is  not  rare,  in  these  cases  by  careful  investigation,  to 
recognise  abundant,  hut  small  granulations,  which  have  escaped  a  care- 
Iflw  examination.  In  order  to  find  them,  the  pia  mater  is  removed  at  the 
points  where  the  tubercles  arc  usually  developed,  which  arc  the  fi»iurcs 
of  Sylvius  and  the  anterior  peduncles  of  the  cerebellum.  A  shred  of  tlio 
membrane  should  be  washed  in  water  to  scpamtc  the  adherent  fni^nenfc»  of 
the  cerebral  pulp,  when  they  are  seen  as  small  whitish  granule».  This 
examination  is  not  suthcient,  the  pia  niater  should  be  spread  out  with  care 
npoii  a  glass  slide,  when  with  low  magnifying  power  the  granulations, 
which  could  not  be  recognized  by  the  unaided  eye,  are  now  perceptible. 

The  study  of  a  single  granulation  «hows  it  to  be  formed  of  a  collecùon

their  proxiaiatc  cause,  consists  in  anourijinal  dilatations  of  the  soiall 
arteries  and  capillanct^  of  the  enct^'pbalon. 

Two  distini^t  forms  of  liemorrliji;^  are  met  with  iw  the  brain  :  capillary 
hemorrhage,  and  that  where  tlie  oxtravasatod  blood  is  collectetL  into  a 
mass,  or  so  called  focus. 

OapiUarjf  heinorrhitf/e.  or  capillary  ftpoj)loxy  of  Cniveilhier,  is  either 
locate^!  in  tho  convolutions  or  in  the  central  portions  of  the  brain.  The 
part  of  the  brain  where  the  lesion  occurs  is  soCtenod  and  strewn  with  rc<I 
points,  which  at  tin^t  si(;lit  rvtcmble  small  drops  of  dark  ami  con 'filiated 
blood.  When  tlie  cerebral  tissue  around  these  red  points  is  torn  with 
needles,  it  i*  found  that  they  correspond  to  vessels,  which  may  be  fol- 
lowed and  isolated  for  some  distance.  Around  tlie  very  tlark  red  points 
the  slightly  softened  cerebrnl  ti^tiie  if  colnred  red  or  pink. 

One  of  thcjie  heraorrhapc  points»  examined  with  the  microscope  «howfl 
at  first  only  a  collection  of  blood,  Imt  by  careful  washing,  it  it*  found  to 
have  ill  its  centre  a  capillary  ve«el,  the  lymph  sheath  of  which  is  dis- 
tended and  filled  with  bloo-d.  nie  red  corpuscles  have  also  eiwaped  be* 
yond  the  lymph  sheath,  among  the  nerve  libres  which  have  been  separated 
and  broken.  Ksch  of  these  small  hemorrhagic  spots  is  therefore  com*

A  fatty  detjeneration  of  the  wall  of  the  central  capillary  is  frequently 
ohserved  ;  the  lymph  sheath  is  cimiiderably  cnlnrge<l;  but  the  rupture 
or  fissure  through  which  the  blood  passed  out  of  the  vessel  1»  not  usually

a  large  artery,  or  be  the  rpiiuU  of  the  coniluencc  of  numerous  points  of 
capillary  hemorrhage.  The  lymph  sheath  diKteiided  by  blood  may 
I  rupt\ire  ;  small  loci  thus  t'oroicd  func  togiMhor.  and  intimately  mini^lQ 
with  the  cerebral  substance.  "Capillary  hcmorrbagc  may  then  precede 
a  true  hemorrhage  ;  it  is  the  first  stage  of  a  hemorrhage  which  later 
aecimiitlates  to  form  n  focus"  (Bouchard).  Frccpiently  there  arc  fomui 
around  heniorrhitgic  foci,  even  the  largest,  a  number  «f  small  point*  oi 
foci  of  cttpillury  hemorrhages. 

If  the  heiiKirrhn^i-  necur  at.  the  corpus  striatum  or  tlialamu.i  optiouii, 
the  lilooil  may  break  into  one  of  the  lateral  vi-ii  trie  lea. 

A  Jiemorrhage  in  the  conical  layer  of  the  hi-ain  near  its  surface, 
gradually  siircading  as  the  blood  eacajtes,  may  force  a  passAge  titrovgh 
the  cerebral  substance  and  uplilï  the  pia  mater,  or  even  break  through 
this  membrane  and  escape  into  the  large  cavity  of  the  araclinoiJ. 

The  most  common  location  of  hemorrhages  is  the  corpus  striatum, 
thalamus  opticus,  and  more  lurcly  the  white  aubatiiDiM.  They  are  also 
met  with  in  the  cerebellum  and  pons.  Hemorrhages  sometimes  occur  in 
Several  foci  at  diflerent  times,  but  are  generally  unilateral.  When  the 
quantity  of  blood  is  considerable,  it  breaks  through  into  one  or  more  of 
the  veniricle». 

Large  extravasation»  occasion  a  tumefaction  and  softening  of  the

When  the  accident  occurs  only  two  or  three  days  previous  to  death» 
the  blood  and  clot  are  red,  as  aUo  the  «alls  of  the  focus.  This  is  the  most 
favorable  time  to  Study  the  condition  of  the  vessels  which  surround  the

an  arteriole,  whicli  ctplatna  the  )ar;^e  sinount  of  blood  and  aixe  of  tlie 
fociiH.  Finally,  there  may  be  rccos"'^'^'!-  ""  Charcot  and  Bouchard 
have  pointed  out,  a  dilated,  ruptured  arteriole  within  a  lymph  sheath, 
■too  raptured,  and,  to  the  interior  of  the  arteriole,  a  fibrinous  clot  coii' 
tinnous  with  that  of  tbe  focus — a  most  palpable  proof  of  the  cause  of 
the  hemorrhage. 

Tbe  places  of  election  for  those  aiicuriains  are,  in  tlic  order  of  their 
fmiuvncy,  the  thalamus  opticus,  the  corpus  Htriatuin,  thv  cvrebral  convo- 
luttona,  and  the  pia  mater. 

These  Binall  aneurisms,  described  as  tnitiar^  OHeurimH»  by  Charcot 
&D<1  Bouchard,  are,  according  to  these  authors,  due  to  arterial  soleroisis, 
particularly  to  periarteritis.  They  iiuist  ii|>on  the  point  that  hemor- 
rhage* arc  generally  caused  by  miliary  aneurisu»  and  periarteritis,  while, 
on  the  other  hand,  Hofteninji  ia  mo.it  usually  connected  with  endarteritis 
attd  atheroma.  But  it  Is  to  be  remembered  tliat  the  leaions  of  periartcritia 
and  atheromatous  cndarioritia  are  very  often  united. 

In  every  case  of  cerebral  hemorrhage  occurring  in  old  poreons,  there 
are  found,  disseminated  in  the  substance  of  the  brain,  miliary  ancurismt, 
which  in  developing  have  excavated  spaces  in  the  white  or  gray  sub- 
stance. 

A  hemorrhagic  focus,  formed  by  the  rupture  of  a  large  vessel,  or  by 
the  union  of  iteveral  small  foci,  distibcos  the  lacerated  cerebral  substance, 
tlie  nerve  fibres  of  which  are  broken.  The  wall  of  the  focus  is  formed 
directly  from  the  cerebral  pulp  ;  it  is  ragged  and  stained  red  by  tlie 
Mood. 

If  the  patient  doea  not  die  immediately  after  the  accident,  certain 
tnwiifi  cation  s  take  place  in  the  hemorrhagic  focus.  The  escaped  blood 
undergoes  the  transformation  that  has  previously  been  described:  the 
fibrin  coagulates,  the  âuid  is  {^dually  absorbed,  and  the  coloring  mate- 
rial of  the  blood  passes  into  the  state  of  rod  or  yellow  granules,  which 
finally* become  bronn,  or  form  crystals  of  ba>matoidin.  During  this  time, 
the  wall  of  the  focus  becomes  smooth;  an  abundant  formation  of  new 
connective  tissue  springs  from  the  elements  of  the  neuroglia,  and  forma 
a  true  fibrous  membrane,  which  is  visible  a  month  after  the  oocurrence 
of  the  hemorrhage. 

The  isolated  nervous  elements  undergo  fatly  degeneration,  and  the 
medullary  substance  is  reduced  to  granules. 

Secondarily  there  is  produced  an  inflammation,  which  terminates  in 
the  formation  of  fibrous  tissue  in  which  are  foun'l  fatly  granules  an<l 
grannies  of  hœmatoidin.  Thus  the  wall  of  a  focus  may  have  a  consider- 
able tliickness,  a  structtire  which  consists  of  connective  tissue  in  the  process 
of  fibrotte  organtialioii,  and  may  inclose  crystals  of  hiematoidin,  pigment,

is  to  be  found  in  the  diseaitdl  heart  or  large  veiueU. 

The  left  middle  cerebral  artery  is  more  freijuently  obtttrncted  than  any 
other  cerebral  ves.iel. 

T'he  first  phenomenon  manifest  in  the  parts  which  the  vessel  su|)plios 
is  a  stasis  of  the  blood,  followed  by  a  more  or  less  rapid  falty  degene- 
ration of  the  Civils  and  nerve  fibres.  Notwithstanding  the  constancy 
of  the  histological  lesions  which  characterize  theae  auocessire  changes, 
the  altered  part  may  present  to  the  unaided  eye  very  varied  appearances. 

In  one  variety,  the  elements  simply  undergo  a  slow  fatty  degeneration.

ami  which  are  formed  from  the  >lâbna  of  the  veaaela  tliat  hav«  reaist«d 
dcj;;eTieralion,  If  the  wall  of  the  softened  focus  is  examined,  th«r«  are 
found  the  deiritiis  of  tiic  ncrvoua  elomonta  and  some  granular  corpusclei). 
The  vessels  themselves  are  covered  with  the  same  fatty  granules  :  hy 
ahakin;^  in  water,  their  surface  is  freed  from  this  granular  d<Shri«,  and  the 
following  peculiarities  are  observed.  Tliey  arc  empty  or  filled  with  blood 
or  ft  yellow  grnDiilftrmH»».  The  lymph  islu-nth  surrounding  them  is  dilated, 
generally  in  n  very  irregular  manner.  In  the  iiiu-tior  of  Iho  sheath  are 
econ  ooll«  loaded  with  pigment  aiul  fnlly  gninnW  (granular  coqiuselex), 
and  the  detached  or  partly  adherent  endothelial  cell.4  also  contain  a  few 
fat  granules. 

The  softened  foci  may  cicatrixe  hy  a  proceai  similar  to  that  described 
for  the  apoplectic  foci. 

A  portion  of  the  fluid  is  absorbed,  the  elements  of  the  neuroglia  which 
surround  the  focus  untlcrgo  proliferation,  and  there  is  formed  a  limiting 
membmne  varying  in  thickness,  in  which  are  seen  many  reescls.  Finally, 
after  one  or  two  yean  there  is  found  a  true  cyst,  flllcd  with  ft  transparent 
seroug  fluid  ;  the  walU  of  which  dilTer  from  tho^e  u  hich  are  cauited  by 
n)inplectic  foci  in  not  containing  a  notable  amount  of  Mood  pigment. 

'liie  infarcli  which  involve  only  the  surface  of  the  convolutions,  pre- 
sent analogous  modifications,  but  les*  marked.  Sometimes  they  become 
softened  and  are  transformed  into  a  soft,  diffluent  patch,  nresenling  a 
peculiar  yellow  color,  suggesting  the  presence  of  hiemaloiain,  although 
no  trace  of  it  can  bo  found. 

A  smsll  stream  of  water  is  sufficient  to  completely  break  down  thc«o 
yellow  paWhe».  The  si«e  of  a  patch  may  be  so  large  as  to  oxtenfl  over 
the  entire  surface  of  a  cerebral  lobe,  Sunictînivs  they  are  dried  and 
sunken,  Jiml  uppi-ar  hanl.  But  the  résistance  is  only  apparent,  for  tbey

S'lftfiihi'ifniiit  Athnroma  and  Arterial  T/irtn»l«ttig. ~~lt  is  generally 
the  result  of  atheromatous  disease  of  vesjtels,  beginning  usually  in  the 
arteries  at  the  base  of  the  brain.  The  endarteritis  causes  a  narrowing  of 
the  ealibi-e  of  (he  vessels,  and  the  blood  stasis  which  then  resulis,  oc- 
casions necrosis  of  the  cells  and  nerve  6bres.  Sometimes  the  irregu- 
larities of  the  intenial  surface  of  the  atheromatous  arteries,  also  deter- 
mine the  formation  of  thrombi  which  obstruct  the  vessel.  This  takes 
place,  for  example,  in  eonsenuencc  of  an  acute  or  chronic  endarteritis 
of  one  of  the  arteries  at  the  base  of  the  brain,  when  prominent  elev».

As  in  old  embolic  infarctions,  jtoft^uin^  from  atheroma  is  ofteu  manifested 
in  the  centnl  [«irtion  of  the  brain,  by  a  fnciw  fitlid  with  a  Horon*  liuid,  or

tlie  form  of  diffiised  or  Girctini<icribed  iiiflainmatory  neoplaaraa  ;  the  latter 
constitutin};  al»ceases  of  the  brain. 

The  brain  substance  is  sometimes  red,  when  the  cHange  is  described  as 
rtd  infinrnnutlorif  »i>jy«ninf^  by  some  authors;  again  it  ta  yollow,  «lue  to

autliom.  Tlic  hiHtuto;;iciil  process  of  inflammation  of  the  brain,  bait  been 
expvrimenlally  sttiiiied  by  Bouchard  and  Haycm.  They  produced  the 
diM'asc  by  dm  direct  action  of  forci<;n  hodic»  or  ohoraical  subttanccQ  upon 
ilie  cerebral  tiamie.  They  aihrro  that  in  inflammatory  softening  there 
exisUi  a  proliferation  of  the  cellular  element»  of  the  nenro;;lia.  It  is, 
however,  very  probable  that  some  of  the  new  cellular  éléments  are  white 
blood  corpuscles  from  the  bloodvessels.  The  new  elements  are  collected 
into  masses,  varying  in  size.  Accumulations  of  new  elements  also  are 
found  in  the  lymph  sheath,  bocwoon  its  limiting  membrane  and  the  wall 
of  the  bloodvGSS^-U.  ThoHC  elcmcnrs  are  nothing  more  thau  white  bloo<l 
oorpiucles  accumulated  in  the  lymph  system. 

At  Uie  same  tinH-  ihitt  the  neuroglia  participates  in  the  inflammatory 
new  forDUition«,  the  nerve  elements  undergo  fatty  degeneration. 

The  iiiflamniiïtory  process  studied  by  expertmentii,  u  similar  to  pri- 
mary  acute  iiiflannunlion.  Thi.i  may  terminate  either  in  an  abscess  or 
softening  of  the  et-rebral  sub^t-ince.  The  color  of  the  softening  may  be 
either  yellow,  whiti-ih,  or  red.  due  to  hemorrhages  in  the  lymph  sheaths, 
or  to  intense  con^eâiion  of  the  capillaries. 

Subacute  intlammatinn  of  the  brain  may  bo  idiopathic,  and  at  the  be- 
ginning occupy  the  centre  of  a  hemisphere.  It  may  also  develop  spon- 
taneously in  the  foetus  and  new-bom  obildreii,  a  form  describnl  by 
VirchoK  Kf  tlifuted  enn;fenital  rnrrphalitiê.

In  tJic  first  stajrc,  the  rapid  niulti)<licatioti  of  the  element*  of  the  neu-

«iDilar  to  that  seen  in  liHiiue.<i  compo»ed  of  embryonic  elements. 

llie  secotul  »Uigf  is  remarkable  for  tlie  airophy  of  the  new  clemeuta, 
and  the  development  around  them  of  numerous  Ghrils,  vhicb  are  ex- 
tremely fine  mid  interlace  in  every  direction.  Tims,  the  cerebral  tiivno 
ia  hard,  resisting,  and  if  cxnmined  witli  liï^h  magnify  tnj;  power  the  fibrils 
are  seen  to  form  a  true  nt-twork,  in  the  midst  of  which  nre  found  atrophied 
nervous  clemcnU  and  sniull  round  or  oval  nucleated  cells. 

In  the  same  brain  hotli  stages  of  the  disease  may  he  found. 

Idiopathic  eelerosl*  of  the  cerehrum  nnd  cereWltHm  i*  met  with  in 
idiots,  cretins,  and  sometimes  in  epileptics  ;  most  freipiently  the  leiiioii  is 
then  localized. 

Wiieu  the  disease  involves  only  one  or  two  of  the  cerebral  oonvolu- 
tion^,  ibey  are  at  first  found  turjjid,  semi-transparent,  soft  and  ^eUiinou9 
I»  the  touch  ;  later  they  are  small,  not  prominent,  and  so  bard  ^lat  the 
nail  can  barely  indent  them. 

Tliis  scle)-osis  almost  exclusivelv  invades  the  convolutions.  Tliero  is 
seen  a  lesion  of  the  nerve  cells  in  tiic  convolutions,  which  we  have  several 
tiinea  noticed  ;  it  consists  in  u  very  evident  removal  of  pi^^nont  from  them. 
Tlie  cells  arc  ab>iulntely  free  from  pi^nent,  and  tninspiireiit,  ii  little  atro- 
phied although  ibcy  preserve  their  angular  sliajw.  When  tbe  legion  is 
very  chronic,  and  the  tissue  very  hani,  the  nervous  elom<tiits,  both  cell» 
antl  libres,  are  neariy  all  atrophied  or  have  complotely  disappeared. 

There  almost  always  constantly  exist,  in  sclerusin  of  the  brain,  upon 
the  surface  of  the  alrtijihied  convolutions  and  in  llielr  substance,  nume- 
roiiA  disseminated  cor]K>ra  aoiylacea. 

Finally,  with  sclerosis  may  be  classed  the  lesions  of  the  brain,  occur- 
Ttn;ç  around  cerebral  tumors  and  particularly  lar^o  tubercles.  There 
oceura  a  new  fonnation  of  embryonic  tissue  which  atrophies  and  is  re- 
placed  by  fibrils,  exactly  as  in  the  second  stage  of  sclerosis.    Cbronie

nerves  arc  divided,  their  peripheral  [wrtion»  dcgencrale,  while  the  central 
«mU  presenilis  their  connection  with  the  mrve  ccUh  of  the  anteriof

shown  that  the  legion  of  nerves  pursuci  an  opposite  direction  when  the

tion with  the  cells  of  the  spinal  ganglia  is  normal,  while  the  M'tiaitire  root 
which  penetrates  the  spinal  cord  becomes  granular. 

Thus,  the  changes  which  arc  seen  in  the  nerve  fibres  of  the  apiual

Îublishcd  in  France  by  Charcot,  Vulpian,  anil  their  pupils,  l'révos*

spinal  parulyinis  of  the  adult  (Duchenne).  and  in  pro^t«sive  mnscuU

primary  myelitis,  limited  to  certain  groupai  of  colls  in  tite  anterior  connu 
which  opinion  ha:«  been  ado|ite()  by  Uajardin-Itoaumetz.  Labonle,  Kng»

S«t.  in.— Pathological  Hiitologj  of  th«  Spinal  C«rd. 

CoxiîEgTiox. — Congestion  of  the  spinal  cord  occurs  during  oongestioo 
And  inflammation  of  the  spinal  meninges,  in  tvphoid  fever,  in  aoae  casee 
of  rheumatism,  in  febrile  diseaaos,  and  in  cïironic  lesions  of  the  heart. 
It  is  charactcriEod  W  disu-nsion  of  tho  vcawls.  Schrtilcr  van  dcr  Kolk 
has  advanced  the  opinion  that,  in  every  ciiae  of  epilepsy,  the  m«<tulla 
ohloiigata  is  congested  ;  hut  this  has  not  been  eutEciciitly  eslablishwl  by 
ol)«ervulions. 

IIi:uoKKnAtii;. — This  lesion  is  very  rare  comparatively  to  that  of  the 
brain  ;  hnwevor,  it  it)  sometime»  m«t  with,  and  in  ebaraeterisiod  by  an 
extravAjiation  of  Mood  into  the  gray  Kubstancc.  The  hemorrhage  ta 
u»na]ly  seated  in  the  gray  centres  of  the  cord,  and  it  may  extend  some 
distance  0&i^^"timctrcs,  Liouvillc). 

According  to  Charcot  and  Ilayom,  this  lesion  is  always  consecutive 
to  myelitis. 

SoFTESlxo. — A  softening  which  follows  an  arterial  emholu»  or  an 
atheromu  of  the  vessels  of  ttie  spinal  eonl  seldom  occurs  ;  th«  lesion  is 
limited  to  a  region  of  the  organ  varying  In  extent. 

The  color,  ooii»i#tenco,  and  !*tnicture  of  Iho  Roftenc>d  portion  vary 
exactly  in  the  same  maiiner  sis  in  the  iteveral  forms  of  cerebral  sol^niug 
studied  above,  so  that  a  minute  description  is  not  necessary.  Sometimes 
tho  softened  part  is  ditllueut,  wbîiish,  ami  opai^uc,  giving  upon  section  a 
milky  fluid  ;  or  it  may  be  dry,  yellow,  shrunken,  and  atrophied  ;  Uie 
hariiness  is  only  apparent,  for  a  small  stream  of  water  causes  a  separation 
of  tb«  «lemcnta,  wbiuh,  mixing  with  tho  water,  give  to  the  latter  a  milky 
wpearance.  In  both  eases  there  are  found,  hy  utîcroscopie  cKamina- 
tiou,  as  in  the  brain,  nunieru\i»  granular  corpuscles  coming  from  the 
granular  destruction  of  the  me<Uitliiry  sulistance  of  the  nerve  fibres,  as 
well  as  altered  vessels  thu  lymph  sheath  of  which  i»  filled  with  tlie  same 
elcmenW. 

Softening  of  the  spinal  cord  is  very  freiiuently  aeen  in  casea  of  oom- 
pression  by  a  tumor  of  the  spinal  meninges  by  an  osseous  tumor  or  by 
chronic  affections  of  the  verlebrie,  a»  in  I'otl's  disease  of  the  spine.  It 
may  also  be  caused  by  a  disease  of  the  brain,  which  kaa  destroyed  a 
large  portion  of  a  cerebral  hemisphere.

in  the  lateral  columns  of  the  «pinul  eord,  that

the  spinal  conl  reiiiaiiui  intact  becaitnc  Uii'  itpinal  Rienin);<>8  are  normal. 

In  I'ott's  disease  of  tlie  njÀnc,  an<l  in  nil  tunion  I'itlicr  of  tlie  verte- 
brte  or  tlic  rocmbraoea  of  Uie  spinsl  conl,  «tiich  occuion  an  inflamma- 
lion  of  the  meninj^cs  and  a  «ofivnin;;  of  the  cord, 
the  latter  is  solWnei),  whiti^li  and  «piii|UG,  or  Tel> 
lowish,  for  a  spac«  oorre^puiKling  to  tlic  «xc  of  tlt« 
tumor. 

When  the  spinal  cord  is  thn*  dwlroyed  in  a  seg- 
ment, the  parts  of  the  spinal  cord  ^iuuttcd  above 
uiut  below  undergo  ch»n;;es  which,  acoohlin^  to  tbe 
investi^nlioDs  of  Tiirck,  Bouchard,  and  (>unelr««, 
seem  to  bft  constant.    They  are  as  follows:  — 

1'he  posterior  columns  show  a  secoudary  degcite- 
ration  almost  throu^hont  their  entire  extent  fsee 
fig.  210)  nhorc  the  point  of  softeuing,  white  below 
only  the  lateral  culmnns  experience  a  chan;>e  (see 
&g,  2m,  <-,  ■■',  and  (■");  the  altération  consists  in 
faUv  dejieneratio»  of  the  nerve  Hbrtm,  in  Iheir 
atrophj.  and  in  llie  presence  of  nnineroua  granular 
corpuscles. 

The  extent  of  the  leùon  in  the  jMMterior  colnmns 
gradually  tJipei*»,  as  one  ascends  the  conl,  no  that 
it  u-rminates  in  n  thin  filament  >n  the  middle  and 
posleiior  pari  of  thu  posterior  colmnu,  (Fig.  ÎÎIU, 
e, /,  <7",mid^".) 

'Die  le«on«  in  the  anterior  oolumns  tenninate 
hUo  in  the  same  manner  o»  one  descends  the  conl  ; 
theiKseat  U  nearly  the  same  as  that  of  degenera> 
don  consecutive  to  a  destruction  of  a  hémisphère, 
that  is,  the  posterior  part  of  tlie  lateral  columns. 

A   sarcoma  which  «e  saw  in   the  nerve*  of  a 

horse's  tail,  had  compressed  and  degenerated  the 

nerves  at  the  point  of  the  tumor  ;  in  this  case  tlie  posterior  columns  of 

the  cord  had  undergone  a  similar  degeneration  throughout  its  entire 

lenirth.  (Kig.  211.) 

What  is  the  cause  of  secondary  dejjcne rations  ascending  in  Uie  poste- 
rior columns  and  descending  in  the  Intcral  columns  Ï  It  is  certainly  coo- 
nected  to  the  circumstance  that  divided  nerve  fibres  become  granular  in 
the  part  separated  from  their  nutritive  centre.  The  cxperiroenu  of 
Waller  have  shown  tlint  if  the  motor  tten'es  or  anterior  roots  of  spinal 
nerves  are  divided,  their  peripheral  portions  degenerate,  while  the  central 
ends  prescning  their  conneciiou  with  the  hiTvi-  cells  of  the  anterior 
eoniua  of  the  spinal  cord,  remain  normal.  The  «apie  experinieiiter  has 
shown  that  the  lesion  of  nerves  pursues  au  opposite  direction  when  ilic 
posterior  roots  are  divided;  the  part  of  the  roots  remaining  in  connec- 
tion with  the  cells  of  the  spinal  ganglia  is  normal,  while  the  sensitive  root 
which  penetrates  tlie  spinal  cord  becomes  granular. 

Thiu,  the  changes  wliich  arc  seen  in  the  nerve  fibres  of  the  spinal 
cord,  in  tbcse  cases,  arc  explained  by  a  separation  from  tiieir  trophic

Tlio  rociilt«  of  phynologicnt  oxporiin«nt«  mudc  by  Vulpian  to  elucidate 
this  i|ueitt)o»  do  not  agree  witli  tUo«!  j^iven  hy  patliologidts.  He  did  uot

li^'  ttie  destniotion  of  a  segment  of  tbe  spinal  mar- 
row. 

In  the  disease  which  will  bo  described  as  tcliraae 
ru  filtiqueM,  in  irbich  the  i^ray  centres  and  white 
columns  of  the  spinal  cord  are  irregularly  destroyed, 
Mcotidary  degcnemtious  of  the  none  fibres  are 
never  seen. 

Vulptnn  concludes  that  the  secondary  dejienen- 
tion  i»  iwi  «olrly  due  to  the  séparation  of  the  nerve» 
from  ilicir  cells,  but  he  believes  that  the  cliBuge  is 
due  to  the  porwatence  of  the  irritation. 

Finally,  when  an  examination  of  the  spinal  cord 
is  made,  from  persons  «ho  have  preiriously  suffered 
amputation  of  the  tiilgh,  or  from  animals  which 
have  had  the  sciatic  nerve  divided,  the  secondary 
Iflsiofu  of  the  spinal  cord  may  occur  not  only  in 
tfa«  posterior  white  columns,  but  also  in  tlie  anterior 
eotumna  and  in  the  celts  of  the  anterior  comua.

Myklitt!:. — Under  tbi^  name  may  be  deaeribed 
a  serieti  of  very  different  pachclogieal  Mates,  in 
which  there  exist»  acute  or  chronic  inflammation  of 
tbe  several  elements  of  the  spinal  cord.  By  tbe 
term  m^etiti»  is  underttood  not  only  true  inflamma- 
tions, cbarscterûted  by  the  formation  of  new  elements,  embryonic  cella, 
white  blood  corpuscles  or  pus  corpuscles  »c»ttered  between  the  elcmenta 
of  the  cord,  bui  also  increase  of  the  cli-mciit«  nnd  lliickomn^  of  the  neu- 
roglia, known  as  fl«ro»ii.  Certain  atrophies  of  the  none  cK-incnts,  which 
conxtilute  tlie  only  lesions  found  at  tbe  autopsy,  arc  likewise  dependent 
upon  inflammation. 

Afulr  gufimrative  mi/riiti»  may  occur  in  epidemic  spinal  menin^iti», 
or  in  eon«e<|uonce  of  ulceruliun.*  of  the  saeruni  which  involve  the  spinal 
dara  mater.  The  myelitis  ii  llien  sii|>erlicial  and  coiiiiecutive  to  the 
meningitis. 

In  some  ca-ies  of  gangrenous  uleeradona  in  the  insane,  the  pnriform 
exudations,  ttie  inflamed  membranes,  and  even  the  surface  of  the  spinal 
«onl,assumc  Uie  characters  and  odor  of  gangrene.  This  lesion  may  ex- 
tend as  far  as  the  medulla  oblongata,  [ions,  and  iiiforiur  part  of  the  brain,

diaianco  fnjm  tho  central  Diaaa  of  the  spinal  cord,  and,  according  to 
Cliurcot  ond  Iluyem,  it  is  in  these  «tses  ibat  hctnorrhaf^a  of  tbe  spinal  cord 
!  occur.  It  is  evrtain  tbat  in  the  coni  as  in  the  brain,  softening  inuT  be 
the  esuso  of  hcmorrhajrus.but  it  is  difficult  to  decide  which  is  the  primarjr 
lesion,  for  primttry  heiaorrha;;es  also  ocuasiun  a  softening  of  tlie  tis«iic 
and  infiltration  of  the  nei';bbonii;;  tii^^uc  with  wUili»  blood  corpufctoi,

complete  degeneration,  aepnration,  and  utropby  of  tbe  parl^  where  the 
leaion  ia  located,  in  which  case  it  exactly  re^einblea  limited  chronic 
softening. 

The  lesions  described  as  characteristic  of  myelitis,  the  impoftaoce  and 
nature  of  vfbich  have  not  yet  been  determined,  are  : — 

1st.  Hypertrophy  and  raricoso  condition  of  Ibo  »sis  cylinder  of  llie 
n«rve  fibres,  obiorvod  by  Frommonn  in  sclerosis,  aftorward»  verified  by 
Revend  anthora  ;  Charoot  has  seen  this  condition  of  the  axis  cylinderv  Id 
recent  acute  myelitic. 

2d.  A  colossal  hypertrophy  of  the  eell»  in  the  anterior  comua  of  llie 
spinal  cord,  otuen'ed  by  Charcot  in  the  «ame  conditionii,  and  appearing 
to  be  due  to  the  same  caiue. 

^d.  Foci  of  granular  degeneration,  described  bv  I^ockhart  Clarke, 
consisting  in  irregular  maeacs,  which  seem  to  come  from  a  coagulation  of 
albuminous  fluid  containing  granules.  These  maaaea  are  conuined  in 
irreguhir  cavities  excavated  in  the  spinal  cord.  As  these  caritica  are 
>  «een  especially  after  hardening  the  cord  in  chromic  acid,  and  as.  on  the 
other  hand,  the  least  traction  is  sufficient  to  tear  the  medullary  fibres,  it 
seem:*  to  n.»  probable  ttiat  they  are  produced  artificially. 

4lh.  The  nniiiorous  and  excellent  works,  whicL   have  recently  been 

Suldiahed  in  France  by  Charcot,  Vulpian,  and  their  ptiptls,  VrévoA, 
offroy,  etc.,  demonstrate  that  there  exists  an  iitropby  of  the  cells  and  of 
the  anterior  coruua  of  the  Hpinal  eoni,  in  infntitilc  paralysia,  in  gvueral 
spinal  paralysis  of  the  adult  (Duclienne),  and  in  progrea-iire  muwular 
atrophy,  Charcot  ia  inclined  to  belîpve  that  this  atrophy  ia  due  to  3 
primary  mvelitia,  limited  to  cerUin  groupa  of  cells  in  the  anterior  corima, 
which  opinion  has  been  adopted  by  Dajaniin-lteaumetz.  Laborde,  Hoger, 
and  ]>amiutchino,  regard  infantile  paralysis  as  cauaed  bv  a  myelitis  with 
proliferation  of  tho  cellular  elements  of  the  neuroglia.  'These  very  inter- 
ealJng  observations  do  not,  however,  seem  to  us  sufficient  to  establish  in 
t  positive  and  definite  manner  the  pathological  anatomy  of  the  preced- 
ing diseases.

in  the  first  stage  numerous  embryonic  elementa  poMesaing  a  round  or  an 
oral  nncleus.  These  cellular  elements  are  imbedded  in  an  amorphous 
granular  substance.  The  nerve  fibres  arc  preserved,  as  also  ai-e  the 
nerve  cells  in  the  anterior  and  posterior  comua.  The  vessels  in  tho 
diseased  re^^ion  bavc  tbeir  lymph  Hheaths  dilated,  and  filled  with  granu-

In  the  posterior  columns,  tlii^  ner«'e  libres  vary  in  diameter,  some 
are  very  small,  altliough  «till  retaining  their  axîâ  cylinder  and  sheath  of 
medullary  substance  ;  others  are  normal  in  siise,  or  larger  than  in  health, 
and  their  axis  cylinder  may  be  considerably  hypertroplitcd.  Between

The  pleani,  the  seroaa  membrane  of  the  thoracie  cavity,  prenents  two 
portions;  the  one,  the  visceral,  covering  the  surface  of  the  lung,  is  thin 
and  conaiats  of  &  layer  of  loose  connective  tissue  invested  upon  the 
external  surface  with  large  flat  pavement  cella  ;  the  other,  the  parietal, 
is  also  lined  upon  its  Free  surface  with  similar  cells,  and  on  the  other 
Bide  is  conlinuouB  with  the  connective  tissue  framework  of  the  intercostal 
muscles  and  the  ribs.  The  parietal  pleura  is  thick  and  consists  of  two 
layers  of  connective  tissue,  the  one  loose,  situated  immediately  under 
the  endothelium,  the  other  distinctly  fibrous  and  containing  a  large  number 
of  elastic  fibres.  This  membrane  possesses  blood  and  lymph  vessels,

RESPIEATOBY  APPARATUS. 


CHAPTER   I. 


NORMAL  HISTOLOGY. 


1^  respiratory  apparatus  consista  of  a  system  of  ramified  passages, 
•bicli  terminate  in  the  lungs,  an  arrangement  something  like  the  ducts 
of  acinous  glands.  The  different  parts  comprise  the  larynx,  t\\&  tranliea, 
t)ie  brimcki,  and  the  air  vende».  The  mouth  and  the  pharynx  appertain 
"wre  particularly  to  the  digestive  apparatus,  and  their  lesions  will  be  con- 
sidered under  that  head.  The  nasal  fossie,  however,  may  be  properly 
Mtoned  as  a  part  of  the  respiratory  apparatus. 

Several  portions  of  the  nasal/ossœ  present  a  difierence  in  structure. 
The  anterior  entrance  bristles  with  hairs  stiff  enough  to  arrest  small 
fwign  bodies  suspended  in  the  air,  and  is  covered  with  a  stratified  pave- 
ment epithelium.  The  nasal  fossEe,  properly  named,  are  lined  by  the 
Scheiderian  membrane. 

ITie  Sehneiderian  membrane  possesses  over  its  entire  surface  a  ciliated 

cjlindrical  epithelium,  and,  throughout  the  greater  part  of  its  extent, 

1!  thick  and  very  vascular.     Moreover  mucous  glands  are  imbedded  in 

it,  anri  empty  upon   its   surface.      The  olfactory   region  is  especially 

remarkable  for  the  termination  of  the  olfactory  nerves.     In  this  region 

the  mucous  membrane  is  tliickcst,  and  presents  a  yellowish  tint.     Its 

cells,  cylindrical  and  implanted  upon   the  connective  tissue  by  a  fili- 

Ibrm  ramifying  extremity,  do  not  always  possess  vibratile  cilia.      The 

iniicous  glanda  are  replaced  by  tubular  glands  analogous  to  those  of 

Ljeberkuim,  vrhich  contain  cells  infiltrated  with  yellow  or  brown  pigment 

granules.     The  pale  nerve  filaments  of  the  olfactory  nerve  terminate  in 

a  long,  slim  rod,  situated  among  the  cylindrical  cells.     Upon  tlie  course 

of  these  terminal  nen'ous  filaments,  which  are  a  little  varicose,  is  often 

found  an  ovoid  vesicular  nucleus. 

The  larynx,  the  tracJiea,  and  the  bronchi  are  composed  of  a  mucous

Kucli  ft  manner  that  the  part*  have  the  diameter,  the  form,  and  the  reac-

strongly  suggests  their  origin,  {f.j.  •/,  fig.  220.)  Such  cell^i  become  ■"

mucous,  cloudy,  or  puriform  appearance,  acconling  to  the  number  ofeell

An  acute  coryza,  uf  a  secondary  cbaracttT,  is  obserrcd  in  the  exau- 
thcmata,  especially  in  rubeola,  in  erysipelas  oî  the  face,  in  diphtheria 
and  (;lan<ler«.  Kacti  of  these  disea:s(-8  may  mitnifcst  itself  upon 
mucous  membrane  of  the  nasal  fossto  by  the  local  character  and  the  pro- 
gress which  cliaractcrixe  them  upon  the  cutaneous  surfaces. 

The  acute  ItiHammation  may  be  arre.ited,  or  it  may  bisiocnc  chronic. 
Chronic  coryxa  and  frequently  recurring  acute  atuictc*  determine  a  thick- 
eniog  of  the  submucous  tissue,  as  well  aa  of  the  connective  tissue  of  tlie 
nucous  membrane  itself,  which  lias  been  pointed  out  by  authors  as  a 
sible  origin  of  polypi  of  the  nasal  fossie.  It  may  aUo  be  accompanied 
by  ulcerations  ana  even  by  small  abscessed  in  the  submucooi  tissue.

Among  the  polypi  of  the  nasal  fosa;e  there  occur  genuine  papHlomata.

In  Urtiaiy  fi/jifiitit,  the  bottom  of  the  nicer  is  covered  with  granula- 
tions «nd  the  aubmucous  liasue  is  thickened,  indurated  at  times,  and  very 
rasoular.  Syphilitic  ulcers  may  extend  over  a  large  aroa  of  the  tnuooai 
membrane  of  the  larynx  and  even  of  tlio  trachea.  When  muted  wpi>n 
the  ejàglottis,  tliey  often  cause  a  loss  of  the  substance  of  ito  free  Iwrder. 
They  fn;(|uent}y  gtve  rise  to  new  formations  of  connevtivu  tisstwt  vege- 
tatiuj;  in  the  form  of  polypi.  These  ulcers  may  heat,  but  the  new  con- 
nective tissue  hft«  a  great  tendency  to  contract  like  cicatricial  tissue  and 
«aiuc  deformities. 

Pnlmonarff  phthim  is  much  tite  tno»t  common  cause  of  laryngeal 
ulcers. 

'L'he  ulc«rs  start  from  a  very  intense  laryngo-tmcheitia,  and  Qsually 
extend  into  the  trachea  and  bronchi.  The  mucous  membrane  is  nsually 
much  coDf;estcd,  and  ia  covered  with  muco-pus.  Upon  the  noD-ulcorated 
parts  tbc  layeiv  of  cîlinted  cyliudrlcal  epithelium  are  still  prescn-e<l. 
The  lesions  which  cause  the  ulcerations  nre  complex:  fir»t  there  form 
tuberonlons  granulations,  primarily  developed  under  tiie  epiUielium,  more 
or  les»  numerous,  isolated,  and  confiuont;  then  follow  follicular  uhxn- 
tions. 

In  the  place  of  the  ginnd  destroyed  by  ulceration  is  seen  a  little  cup- 
shaped  circular  depression.  Theae  ulcer*  enlarge,  and  may  reach  2  to  3 
mm.  in  diameter.  Their  floor  is  grayish  or  rosy  and  is  slightly  de- 
pressed. Thcv  may  unite  with  each  other  and  form  a  large  ulcer  with 
festooned  borders.  It  is  rare  that  tubercular  granules  cannot  be  seen 
upon  the  flour  or  ed^cs  uf  these  ulcers.  Tlic  vocal  cords  at  their  jtoint 
of  union,  the  corN  themselves,  the  arvtcnoid  cartilages,  tlie  epi<;loltis, 
and  the  interior  of  the  ventricles  of  Morgagni,  are  tiie  most  freipient 
seat  of  Itiese  ulcers.  The  ulcers  extend  in  depth  u  well  as  super- 
ficially. 

'i'he  exposed  fibrous  tissue  of  the  vocnl  corils  may  itself  bo  eroded; 
the  free  border  of  the  epiglottis,  also,  frctjucutly  presents  loss  of  sub- 
stance, involving  destruction  of  the  cartilage. 

The  submucous  connective  tissue  arouml  the  ulcerations  is  much  thick- 
ened by  a  new  formation  of  embryonic  cells,  or  it  is  infiltrated  willi 
serum  and  pus.  These  lesions  affect  the  function  of  those  portions  of  tlio 
larynx  where  they  arc  located. 

The  muscle»  arc  aho  sometimes  invaded.  The  inlcrnmscular  connect- 
ive tissue  may  be  infiltrated,  and  the  fasciculi  themselves  undergo  fatty 
degeneration.

Inie  cricoid  cartilage  is  most  frerjucntly  affected,  next  comes  in  order

Conomtiok;  IIkkorriiaor. — Congestion  of  tlie  bronclii  precedes  uid 
aocomjianies  catarrhal  and  other  inflammations  of  tticae  tubes,  and  a 
present  in  almost  all  diaeaaeii  of  the  air  paiaaj-e-i  and  of  the  heart.  It  'a 
'observed  also  in  many  fevers,  such  as  the  eruptive  fevers  aiw)  typlioid 
fever.  It  le  characteriEcd  by  redness  and  liilncss  of  the  Vf-sit-N  and 
Bwelling  of  the  mueous  membrane,  and  most  freijucnliy,  even  lu  pawivo 
congestion,  by  a  secretiOD  of  mucus.  The  inner  surlace  of  tlic  bronchi 
is  red,  often  u  dark  maroon  color.  Kccliymoses  may  appear  in  tbe 
mucous  membrani.-,  particularly  in  the  e\untlioniatn,  in  typhoid  fever, 
in  scorbutus, And  in  asphyxia.  Then  the  broiielnnl  mucus  contains  a  greater 
or  leaser  number  «f  red  blood  gtobuK-s.  Large  bicmoptyMS  arise  from 
ulcerations  of  the  bronchi,  from  puhnonary  cavities,  from  pulmonary  apo- 
plexies, or  from  rupture  of  ati  aneurism  into  the  bronobi. 

BnoNCiiiTifi. — Catarrhal  inflammation  of  the  mucoos  membrane  of  the 
bronchi,  cither  acute  or  chronic,  is  excited  by  the  same  causes  aitd  pre- 
sents, in  H  gcni>ral  nay,  the  same  histoloj^ical  •:han;;cs  as  doi'S  that  of  the 
larynx.  Limited  to  the  lar-^o  bronchi,  it  is  nut  dungerou»,  but  when  it 
invades  the  small  bronchi  it  is  ol^cn  fatal,  especially  in  children  aiul  in 
the  hff.'d.    In  these  grave  ease»,  the  bronchitis  t*  rarely  simple  ;  it  is  com- 

{>licated  with  lesions  of  the  piilnionary  ]iarencbyma,  such  a»  congestion, 
obular  or  catarrhal   pneumonia,  atl^îecla«i>l,  emphysema,  and  lobular 
I  gangrene. 

JitUtme  hrt'Hfhiti»  of  the  small  broncbt,  or  capillary  bronchitis,  may 
be  such  that  tbe  inRammatory  thickening  of  the  mucoiu  membrane, 
added  to  the  products  of  exudation,  prevent  the  air  from  reaching  the 
pulmonary  alveoli.  In  other  cases,  the  diseased  bronchi,  very  red  upon 
Uieir  internal  anrface,  which  is  covered  by  a  puriforra  mucus,  appear  to 
bo  dilated.  The  connective  tissue  of  the  mucous  membrane  is  thickened 
and  the  bronchial  tube  is  more  rigid  than  normal  :  the  natural  longi- 
tudinal rugic  of  the  mucous  membrane,  which  result  from  the  contraction 
of  the  muscular  tnnic  of  the  bronchi,  become  elfacvd,  and  the  internal 
«nrfaee  of  tbe  bronchi  is  smooth.  This  condition  of  tbu  bn)ncbial  tubes 
is  most  fre(|uent1y  seen  iu  broncho-pneumonin.  In  severe  bronehitU, 
whore  the  secretion  is  muco-punilent,  the  cylindrical  epithelial  cells  hare 
dc»i|uamated,  the  glands  are  lilled  with  emhrynnal  celU  and  pus  corpus- 
cles.and  tbe  surface  of  tlie  mucous  membrane, may  present  an  un|iolished 
aspect,  due  to  the  formation  of  microscd]iic  papil'»»  or  granulation^^. 

Dif^'hlheritic  fironehiti*  is  seen  particularly  in  children,  as  a  complica- 
tion of  croup.    It  is  then  generally  associated  with  pulmonary  congestion^

chronic  process,  such  as  branchitis,  chronic  pleurisy,  chronic  pncitmonia, 
these  laocs  remain  dilated.  Almost  ulways  thc^  tissne  which  surrounda

dilatations  alon^  the  course  of  a  bronchus  and  its  branches,  as  is  often 
oliserved  at  the  apex  of  the  !un;;8.  The  dilatations  arc  connected  with 
one  another  by  brnnchinl  tubes  of  normal  diameter — the  ninnitlform  dila- 
tation of  Cruvcilhier.  A  third  am]  most  common  furm  is  an  ampullar 
or  sacciform  dilatation,  gt-nrnilly  »injile  and  frenucntly  very  lar^v. 
Several  of  these  ampullnr  cnlarjçementa  may  conimnuicate  with  one 
«notlH'r  by  the  intervention  of  bronchi  more  or  Icm  dilated,  whence  may 
result  the  convcrs^ion  of  a  lobe  into  an  alveolar  mass,  the  cavities  being 
sep«ntt«d  by  shrivelled  and  indurated  pulmonary  tissue.  The  favorite 
location  of  thexe  dilatations  is  at  the  peripht-ry  of  the  lung,  and  there 
always  exisfc*  in  the*e  cases  a  chronic  pleurisy,  marked  by  the  fihroiw 
thickening  of  (he  pleura.  Beyond  the  dilatation,  the  bronchus  and  its 
terminal  branches  are  atrophied,  or  some  of  the  bronchi  may  be  con- 
verted into  cysts.  Wo  sometimes  find  cystic  cavities,  more  or  less  volu- 
minous, at  the  apex  of  the  lun-is;  they  arc  lined  with  a  mucous  surface, 
and  contain  a  nuieous  tluid.  They  have  been  considerc<l  as  bronchial

tie  Mood  during  an<I  after  tfie  tnoroeiit  of  death. 

Tlie  dietioctton  between  con^iestion  and  true  inflainnmtioii  cannot  he 
sltarjilr  drawn  at  the  hc^nning,  for  in  congestion,  in  the  jilacc  of  tti« 
cells  of  the  alveoli  which  have  dea<|iiiiinatcd  new  cells  rapidly  form: 
there  arc  then,  a»  in  pucutnonia,  new  formation,  of  elemontei,  ami  excape 
from  the  vesucl*  of  white  Uood  corpuscles  ns  well  as  liipior  san;riiinis. 
We  uW  fiml.  in  simple  congestion,  n  fine  mcshvrork  of  fibrin  with  red 
and  white  hlooil  coquisclon;  hut  theite  elements  are  not  numerous  in 
simple  eoii^eatioi!.  whilnt.  on  the  eontmry.  they  rapidly  form  iit  groat 
numbere  in  the  eon;[cstion  which  (irecedc»  pneumonia. 

When  a  portion  of  a  much  oongested  lung  is  at  the  same  time  deprived  of 
air  it  looks  like  ticsh,  and  the  condition  han  been  termed  camitication. 

Chrvnif  hjfperœmio  is  followed  by  more  profound  changes.  IV'e  hare 
already  wen  bow  the  epithelial  cells  may  become  pigmcnted;  similar 
aitl^ntions  may  occur  here.  The  distended  capillaries  of  the  wall;?!  of  the 
alrcxdi  exude  into  tlic  alveoli  and  their  septa  a  highly -col  end  fluid;  the 
coflnective-lis.<uc  cells  stvell  by  imbibition,  and  pigment  granules  are  de- 
posited in  and  around  them.  The  amount  of  this  pigmentation  is  the 
greater  the  more  repeated  and  iiersistent  the  cong('i>tion.  It»  greatest 
intensity  is  seen  in  diseases  of  the  heart  accompanied  by  great  impedi* 
ment  to  the  pulmonary  circulation. 

When  the  hypcriemia  of  the  alveolar  walls  is  very  intense  or  a  long 
tiioe  prolonged,  the  connectiTp.tissne  elements  have  a  tendency  to  pro. 
liferatc  and  fonn  nen-  fibrous  tissue,  principally  around  the  bronchi  and 
the  vcMtcls.  This  thickening  of  the  pulmonary  tissue  \s  really  the  first 
stage  of  interstitial  pneumonia. 

A  dark  color  of  the  lung  may  have  a  cause  other  than  that  just 
dewnbed.  It  mtiy  be  due  to  the  penetration  into  the  ultimate  ramifi- 
cations of  the  bronchi  and  into  the  parenchyma  itself,  of  line  particles  of 
diuit.

ATBLBCTAHtH. — ^Tliis  Winn,  which  consists  in  the  ahsolute  aheoncc  of

pneumonia,  and  in  comprcwiion  of  the  lun^  by  a  tiunor  or  by  a  pleurisy. 

Tlic  alveoli  no  longer  contain  air,  llicir  cavity  is  elTaccil.  and  thoir 
waIU  arc  in  contact.  Tlic  iDO!>t  extensive  ut<-1(M.-tasis  of  the  lini^  is  titat 
which  is  caused  by  the  coinpr(^»fi"Ti  rt^Hidlinf;  fi^m  a  iitiilalcrul  pU-iirisy 
witli  great  effusion.  The  compressed  lung,  in  the  latter  case,  is  sur- 
roundeil  by  a  much  ihickeiicd  pleura,  which  prevents  it  from  fully  ex- 
pan<ling  again,  oven  after  inflalion.  If,  however,  wo  remove  the  lihrous 
em'cl'>)>e,  we  can  rcadilv  a.i.4ure  ourselves  that  the  pulmonary  parenthyina 
is  intact,  for  the  alveoli  resume  their  form  when  the  pleura  which  bridles 
them  has  been  removed. 

In  atelectasis,  the  alvcolî  may  be  altogether  empty,  or  they  may  con- 
tain in  thrir  interior  n  Biiî'l  holding  in  siispciisiun  large,  spherical,  gniiiular 
cells,  like  tlnwe  fourni  in  congestion. 

The  nffeeted  tissue  is  flesh-likc,  and  sinks  to  the  bottom  when  plunged 
into  water;  u|iiin  Kcction,  it  presoiit**  a  violet-iyrd  color;  it  is  dry,  l')ii>;h, 
fimooth,  unilVtnn.  and  it  iii  not  indented  by  digital  pressure.  Tlii.*  coik- 
dition  very  «ell  corresponds  w  that  of  the  lung  of  a  child  which  has  not 

('et  respired.  It  is  most  fre-iueiiilv  eiicnuutered  at  the  periphery  of  the 
ung,  at  its  sharp  borders,  diasominated  in  jioinls  which  are  freijuentlv 
small,  as  in  hroncho-pneumonia.  In  this  case,  the  anatomical  lesion  is 
the  rcstilt  of  the  obstruction  of  a  small  bronchus  or  hroncluolc  by  a  plug 
of  unicus. 

Inspiration  is  too  feeble  to  cause  the  air  to  penetrate  ;  but  the  expira- 
tory force,  which  is  dm»  only  to  the  elasticity  of  the  lung,  remaining 
unabated,  the  air  is  gnuhially  cx])cllcd  fnim  the  alveoli  supplicij  by  the 
obstructed  broiicbni»,  and  atelectasis  follows.  The  !«arae  result  cim  be 
protliiced  in  much  the  same  manner  by  compression  of  the  lun^;. 

FaUe  pleuritic  membranes,  or  indiii-alion  of  llie  intiame<1  pleura,  render

foci  in  one  or  both  tunjrs. 

These  gangrened  or  softened  spots  arc  always  found  to  be  surrounded

When  one  of  these  indurated  foci  is  cut  open,  three  distinct  zones  are

In  the  interior  of  the  contracted  alveoli  there  are  nmnd  cell*  of  tl»e

Artificers  in  iron  and  stoci  are  subject  to  a  similar  form  of  pneumonia

Eray,  and  yellow  hejiatixation.  We  believe  that  this  difTerence  in  color 
IS  due,  in  the  one  case,  to  the  effusion  of  blood  into  the  alveoli, and  in  the 
otiiers.  (o  the  abundance  of  fatty  granules  which  are  contained  in  them. 

In  these  cases  of  chi-onie  pneumonia  the  inieralveolar  s«pta  are  thick-

Jinch'Kiilr-nnata  have  been  seen  in  the  lung  only  as  secondary  fonoa 
tjons  after  the  development  of  an  enchondroma  in  another  organ. 

Primary  Carcinoma  of  the  limg  is  very  rare.  It  is  most  frw)ucntlT 
onc«pluiloid,  and  is  found  mon-  often  in  tlie  right  than  in  th«  loft,  but  it 
may  invade  both  lungs,  the  ont'  aftor  Ibo  otlior.

a  care  i  noma  to  UM  trannfurinatiou. 

Upon  ciittiii);  into  the  diseased  partj*,  it  \*  common  to  observe  whitish 
island.^  or  granulations  similar  to  those  of  the  bepatir.cd  lung.  se|»ratei)

surface  with  a  scaljK-l  tlieite  granulations  arc  removed,  and  a  milky  fluid

rouiul  cells  between  their  fibres.  Their  vessels  are  gorged  witli  blood. 
There  is  therefore  no  stroma  of  new  formation  in  carcinoma  of  the  lung, 
but  the  fibrous  trabecule  are  conadtutod  by  the  altered  inter-alveolsr 
eepta. 

Carcinoma  of  the  lung  may  givo  rise  to  ulccnttJons  or  caverns,  vhidi

Colloid  carcinoma,  which  is  comparatively  common  in  the  lung  ae  a 
sequel  of  a  primary  tumor  of  the  same  nature  developed  in  the  muoom 
membrane  of  the  alimentary  or  biliary  canals,  presents  itself  under  th9

Instead  of  being  gray,  caseous  pneumonia,  which  is  older  ai>d  in  which 
tie  granules  arc  more  abundant,  ofi'crs  a  yellow  color.  Save  in  color, 
the  appearance  is  the  same  as  in  the  gray  infiltration,  and  the  constittition 
is  also  similar. 

In  certain  eases  of  this  kind  of  pneumonia  there  are  no  tubercle  gran- 
ules to  be  roco;imKert  Dither  liy  the  nuked  «yp  or  by  the  micmwnfw. 
Il  may  bo  that  they  have  been  present  norertliele««,  but  in  coufletguence

Aeconling  to  lirancher  there  is  always  in  ca!<eous  pneumonia  a  certain 
amount  of  interstitial  pneumonia  in  places. 

Considerable  masfics  of  this  tuberculous  pneumonia  may  remain  un- 
changed for  a  long  time,  when  the  lung  continues  impermeable  to  the  air 
and  to  the  blood. 

Cavities  are  farmed  in  this  variety  of  tuberculous  pneumonia  in  the 
same  manner  as  has  already  been  indicated.  ^Vbcn  the  loe»  of  substance 
has  reached  the  nonnal  pulmonary  tisfuc  the  destruction  id  arrHtcd  and 
the  furrounding  tissue  is  indurated  by  a  chronic  inflammation,  accom)«- 
nicd  by  the  formation  of  connective  ti**ue  in  the  intcralvcolar  nepta  and 
even  at  the  surface  of  the  cavity.  Upon  the  latter  we  find  sntall  vascu- 
larized  granulations  beneath  tlie  pulpy  or  puriform  covering  which  line* 
Uiem. 

ITifire  9ometimi>it  exii^t  also  in  this  layer  of  granulation,  small  anourifflus  i 
which  arise  by  ililatatton  of  the  branches  of  tiio  pulmonary  art«rv,  which 
softened  by  inllammatîon,  become  distended  by  the  blood,  Bv  their 
ru|»ture,  these  aneuriums  often  give  rise  to  fatal  hjemoptysis.  V'esscls 
and  lar^e  bronchi  often  extend  across  targe  cavities  ;  such  trabeculie  arc 
also  covered  with  a  layer  of  granulation  tissue. 

Later,  the  inner  surface  of  the  large  cavities  is  smooth,  almMt  as  if 
it  were  covered  by  a  mucous  membrane. 

The  interstitial  pneumonia,  aided  by  the  chronic  pleurisy,  the  6bniti8

no  tubercles  are  to  be  sc«n,  the  attempt  has  been  made  to  et^ilabliAb  a 
form  of  acrafuIouB  pneumonia  independent  of  tubereloa.  But.  wlicii  the 
«hole  of  the  lun^  '"  oxnmined,  we  almoat  always  6nd  very  distinct  gran- 
nies in  other  part*  of  the  orsiin  or  in  the  pleura,  citlier  viscenl  or  costal,

But  there  exitita  a  form  of  tuberculosis  in  whieh  the  granules,  however 
numerous  they  may  be,  are  everywhere  surroundetl  by  a  pigmented 
interatiljal  pneunioiiia.  The  tuberculous  proccis  is  then  more  or  les» 
rapid  in  its  maroli  :  but  there  is  no  very  great  tendency  to  tlie  det«r- 
mituition  of  a  lobular  or  lobar  pneumonia. 

ITie  general  distribution  of  tubcrcnloua  lesions  of  the  lungs  is  such

of  vegetations,  small  villous  growths  consistuif;  of  connective  tissue,  and 
often  also  in  a  hydiothorax.  The  pleura  is  whitish  and  untransjiarent. 
This  condition  is  Irefjucntly  but  slightly  marked,  and  considerable  practice

In  this  owe  the  pleuritic  exudation  contains  very  many  white  corpuHcleft,

upon  the  surface  of  the  visceral  pleura  the  vessels  are  found  congested 
anil  prominent  ;  they  may  even  project  above  the  surface  in  the  form  of 
vaticular  vcgetaliouâ.  It  is  upon  these  vascular  loops  that  the  fihrinoufl 
exudation  is  thickest.  Tlie  pleura  is  itw-'lf  thickened  and  infiltrated  witli

The  idiopathic  pUurittf  which  follows  an  impression  of  cold,  for 
example,  is  variable  in  it«  termination  and  in  the  nature  and  abundance 
of  the  effusion.  It  i»  always  characterini.'d  by  a  layer  of  fibrin  de-

effusion,  the  amount  of  which  varies  betwoeu  J  to  IJ  litres. 

Both  the  parietal  and  visceral  plcune  are  at  first  eongested,  and  very- 
soon  (during  the  first  day)  they  are  covered  by  a  thin  layer  of  fibrin  ; 
at  the  same  time  tluld  is  efliised  into  the  cavity.  The  effusion  increaaca 
during  the  SHCceedinu  days,  and  the  layer  of  fibrin  thickens.  Fre4Uontly 
Hakes  of  coagulated  fibrin  float  in  the  fluid. 

The  (iflceral  and  iJic  parietal  pleurœ  are  always  affected.  Thin  vertical 
sections  show  a  large  quantity  of  white  corpusclos  between  the  bundlos 
of  fibres,  increasing  iu  numbers  aa  the  free  surface  is  approachod.  The 
bloodressels  project  upon  the  surface  in  loops.  The  Ij'uiph  vessels  con-

In  certain  simple  pleurisies  with  simple  iieroiis  effu.iion,  lasting  for  <nie 
or  two  months  aiirf  terminating  in  death  due  to  some  other  caiwe,  we  fiml

without  the  intervention  of  a  false  fibrinous  or  cellular  meinbraitc 
uniting  tlie  two  surfaces  of  the  serous  nicmbratio.  In  such  a  case  the 
effusion  is  abundant,  the  lunjr  )j<  compressed  (sec  Atrtectati»,  p.  411), 
and  the  vinccml  pleiim,  briieath  it»  layer  of  fibrin,  is  nc^istHnt,  uu^h

iuci.-iing  the  thickened  pleura,  taking  care  not  to  wound  tli«  pulmonary 
parenchyma,  the  latter  can  again  he  inflated  and  made  to  resume  ite 
original  form.  If  a  thin  slice  of  the  lung,  tlius  conipreitsed,  i*  ])hK'4il  in

that,  in  this  coniprcwion,  the  alveolar  walls  are  flattened  against  one 
another,  but  without  alteriition  of  their  epithelial  or  other  tissues. 

Idio}>athic  fibrinoni^  phuriKy  may  be  aeconipanied  by  a  very  abundant 
serous  efi'ii;«ion  which  may  be  poured  out  so  rapidly  as  to  roach  three,

ClIKO.Nlc  PiXL'KISY. — Chronic  inflammation  is  eolablUhed  at  tlie  otit- 
BUirt,  or  it  sut'cceda  an  BCttt*  plaiirisv.  Tlio  liv|>er|)la^lic  pk'urisy  pi», 
viously  described  is.  in  reality,  a  pleurisy  which  is  chronie  from  the 
beginning,  und  which  manifests  ibself  by  the  foroiation  of  connective 
tissue,  embryonal  at  first.  The  jiroceiiu!  torminateK  in  libmus  thickening 
of  tlie  pleura,  in  filamentous  or  membniii'ius  adhefionc,  or  in  a  eioni|det« 
obi  i  te  lilt  ion  of  the  pleural  cavity.  We  jtl.*o  meet  with  pleiirioie^  chronie 
from  the  first,  which  follow  chronic  lesions  of  the  lung  or  pleura,  ao,  for 
example,  certain  cases  of  tubercular  pnciiinonia.  tumni-s,  etc. 

The  chronic  pleurisy  which  succeeds  an  acute  fibrinous  ])leuri8y  and 
which  is  marked  hy  the  fibrous  transformation  of  false  membranes,  is 
most  frequently  the  natural  method  of  healing.  It  often  hap]>ens  ibat 
these  false  fibrous  membranes  or  the  thickened  visceral  pleura  do  not 
much  interfere  with  the  expansion  of  the  lung  or  the  inoremcut  of  the 
ribs.  But,  when  tlic  effusion  has  bcrt^n  eonsidenible,  when  the  false  metn- 
branca  have  been  very  thick,  and  absorption  iiit<  not  fora  longtime  made 
much  )>rogrcsi<,  the  or;;iiiiixed  false  mcuibianes  and  the  tliiekvning  of  tli« 

fileura  seriously  imjieile  the  dilatation  of  the  lung  in  inspiration.  TlieM 
also  membranes  form  a  solid  union  between  the  walls  of  the  pleura  ;  and 
in  proportion  as  die  fluid  is  absorbi-d  and  the  apace  which  .lejiaratm  ilie 
two  leaves  of  the  pleura  narrows,  the  contraction  of  the  false  mcmltrauea 
draws  the  costal  wall  toward  the  root  of  the  lung.  The  thorax  which  had 
been  dilated  by  the  effusion  contracts,  and  the  ribs  approach  and  touch  each 
other,  especially  at  the  lower  part  of  the  chest,  so  that  tlie  diseased  side 
become»  nuich  sinuller  than  the  healthy  side.  The  slioulder  becomes 
depressed  and  the  vertebral  column  may  even  pre-sent  a  certwu  degree  «f 
scoliosis,  with  the  concavity  towards  the  affected  side.

ralterations  of  ihe  closed  follicles  and  mucooa  glands  of  tlie  pharynx. 

Cpoii  the  coiigoBtod  surface  of  the  pharynx  the  glamls  i)rojeet  R»re 
.prominently  than  in  the  normal  state.     At  the  centre  of  the  glanduiarri 
Iciaineiice,  the  excretory  duct  of  the  mucous  glands  is  oftvn  surroundwil 
by  a  whitish  rim  due  to  the  dcs>|uamatioii  and  swelling  of  ttic  cpitheliall 
cells  ;  the  enlarged  duct  sometinics  contain»  a  puriform  mucus.     TborM

mation  attacks  the  depreavions  of  the  mucou«  membrane  :^ittuilo<I  at  tba* 
centre  of  the  agrainaicd  follicles  which  exist  in  the  upper  part  of  the 
pharynx.     The  tumefaction  of  the  acinous  glands  is  due  simply  to  a  hy- 
pertrophy of  their  culs-do-sac,  caused  by  u  swelling  of  dicir  cells  and  tlic 
enlargcMH-nt  of  the  I'ollieular  glands,  a  hypertrophy  analogous  to  Chat  of 
the  t'>ni<ii».     When  tiic  IcMon  is  older,  glandular  atrophies  are  produced 
by  ulcérations  limited  to  a  certain  number  of  the  glands  nix)  follicleaij

The  bloodvesaels,  pariieularty  the  veins,  are  diitended  and  very  risihien

The  vault  of  the  pharynx,  so  rich  in  closed  follicles,  often  presents  snelu 
an  iiiHanimatory  swelling  of  these  follicles  and  of  the  muooui  tucmbraUH 
which  covert  them,  that  the  orifice  of  the  Kustachian  tube  is  obotructofl

tisaue.     It  is  necc^earv  to  resort  to  the  stmly  of  intiamiiiation  artificially 
produced  in  the  stomach  of  animaU.     We  hare  cxaiained  a  iierieii  uf 
Lltomacbs  of  dogs,  where  irritation  of  the  inner  surface  of  the  orKao 
Ibad  been  produced  by  a  venous  injection  of  diSbrent  eabetancea.    The 
Istomnch  was  found  intensely  coii;;estod  in  various  placM  and  covered  bv 
'a  mucous  or  mttco-puruleut  si-crct4on.     The  ^nslrîc  juice,  when  it  u 
cloudy,  contaiius  a  lBri;e  quantity  of  white  corpiiHcles  besides  llie  super- 
ficial epilhelia,  whicli  are  almost  intact  or  are  filled  nith  mucus. 

In  the  conge»l4-d  iirejut  thin  aeotionA  show,  under  the  mioroacope,  a  mrj 
marked  dirtteii^ion  of  the  »iiiperfiei»l  capillary  network  found  at  the  erests 
of  the  intcrglandutnrproniineneeii.     Tliene  prominences  are  more  aulienl 
thati  in  tlie  normal  state.     In  the  tiasiie  around  their  cagiillary  vc 
extravanations  of  red  and  white  blood  coq>u9cle9  are  often  recogntK^d.^ 
Whence  lesion  is  not  very  pronounced,  tlie  epithelial  covering  remains 
in  place,  but  at  other  points,  where  the  inlerglandular  fohls  are  more 
tumefied  and  the  connective  tissue  around  the  dilated  i-eesels  is  muchj 
infiltrated  witli  the  csc^d  elemouts  of  the  blood,  the  epithelium  is  «oi 
pictely  absent.     The  depressions  of  the  metiibranc  into  which  tlie  glandril 
empty  arc  narrowed  or  even  entirdy  closed  by  the  swelling  of  the  coo 
nective  tissue  which  «urrouwU  them.     They  neverthelexs  reUiin  Ihcîr' 
cellular  lining.   Neither  the  mucouM  i;lan<ls  nor  the  {«jitic  glands  present 
llterAtioDs, 

From  the  foregoing,  gastric  catarrh  artificiallv  produced  Heems  to  con- 
sist  essentially  in  congestion  of  the  surface  of  Uie  mucous  membrane,  in 
the  repletion  of  tbe  superficial  capillary  network  and  the  escape  of  liuid 
containing  red  globules  and  lynipb  corpu«elU!>,  in  the  cedematous  and  ecchy'l 
motic  tumefaction  of  the  interglaridular  prooiinenee»,  while  the  glands  of 
the  stomach  appear  to  take  no  active  part  in  (lie  morbid  process. 

In  man  it  Lk  impossible  to  demoniitrale  all  these  histological  conditional 
yet  the  redness  of  the  membrane,  the  eccliymones,  and  Uie  character  of 
tlie  fluid  secretion,  indicate  with  suthciont  certainty  a  su{)erGcia1  catarrh 
of  the  stomach. 

In  a  whole  series  of  infectious  febrile  diseases,  such  aa  pnerper 
fever,  variola,  etc.,  wo  meet  with  a  grayish  paleness  of  Ibe  glandular.] 
layer  of  the  stomach,  which  is  more  or  le$g  mammillatcd.  The  glandular 
celts  arc  swollen,  cloudy,  and  filled  witli  fine  fiitty  or  protein  granules; 
they  are  in  contact  with  each  other,  and  their  outlines  are  indistinct.  In 
(lie  sidient  folds,  the  glands  are  enlarged  :  they  are  in  a  state  of  fatty 
degenemtioTi  analogous  to  that  which  we  see  in  the  liver  ami  kidneys  of 
the  8ame  siihject8.  It  is  possible  that  post-mortem  liecomposition  plays  i

«leer  is  then  cunstituied  by  smooth  muscle  fibre*.  Tbe  latter  in  their 
turn  disapjionr  little  by  Hulc,  and  there  then  remains,  of  the  wall  of  the 
stomach,  only  the  peritonenl  tunic.  When  this  final  coat  is  eaten  away, 
there  is  a  communication  between  the  cavity  of  the  stomach  and  that  of 
tbe  peritoneum,  or  ti>e  bottom  of  the  ulctir  is  bounded  bv  the  neighboring 
organs  with  which  tbe  peritoneum,  at  this  location,  has  lormed  adbeaioDS. 

When  Uic  mucous  and  submucous  tissue,  and  suhs(.'t(uenlly  the  mus-

'I'lio  shape  of  the  ulecr  corresponds  to  tlie  area  of  tissue  nourislie<d  by

Upon  the  sbarply-ciil  stalls  of  the  ulcer  sniiill  arteries,  and  u;  the  ttottoa

Tbe  extent  of  these  ulcertt  i^  extremely  variable.  When  t)»e  Iwitom 
of  the  ulcer  ia  formed  by  adjoining  organs,  the  tiiiHue  of  tlie  latter 
inay  somelimes  be  eroded  to  some  extent.  When  the  ulcer  is  located 
upon  tlio  groat«r  cunature  of  the  stomaeh  it  may  enil  in  a  perforation 
and  a  funeral  peritonitis,  or  an  inflammation  of  the  jwritoncum  localiseil 
by  adhesions.  The  nicer  may  bo  single  or  multiple;  it  may  be  located 
upon  the  lesser  eiirvature.  at  ibc  pylorus,  at  the  enrliac  end,  or  upon 
tbe  posterior  wall  of  the  stomach;  more  rarely  upon  the  -greater  etirv^ 
ture  or  upon  tbe  anterior  wall  of  tlie  or^n  ;  it  may  even  invade  tli« 
lower  end  of  the  ifsophapis  or  originate  in  itic  duodenum. 

When  a  thin  suction  Uirougli  an  u)c«r  ia  examined,  the  wall  of  the 
latter  ia  found  to  coiiHisl  of  tlio  pre-existing  lisstie.     'llie  conncetire  tis- 
I  tue  is  only  a  little  thickened,  but  there  ia  neither  juloo,  as  in  cancer,

connective  tiissue  richer  in  polls  tlmn  in  the  nonnal  stale;  the  epithelial

lissne  is  thickened  somewhat  and  is  rieh  in  fiinifonn  or  rointd  cells  and 
fibres.     In  this  li«suc,  at  the  boiler  of  tlie  ulcer,  lesionit  of  the  vestel 
valU,  consisting  of  a  aclerotle  tliickcning  and  coutnction  of  their  calibre, 
are  constantly  found.     The  ualUof  the  capillaries  are  sometimes  eon* 
verted  into  a  thick  refracting  substance,  which  stainit  deeply  in  carmine. 
In  one  ease  we  found  some  of  the  lymph  vessels  of  the  submucous  tissue 
filled  with  lymph  corpuscles.     In  this  same  ease  the  connective  tissue 
showed  in  spots  a  colloid  metamorphosis  ;  in  these  spote  there  wore  thin 
reticulatod  fibres  of  connective  tissue,  bounding  very  small  alveoli  con- 
tainin-;  a  colloi<l  suVt^nce  an<l  some  lar^e  round  cells.     When  the  ulci

muscle  i^roject  upun  the  wall  of  the  cavity  in  tlic  form,  as  it  wer«,

Tbu  aDatomtcil  dia^piosis  of  this  Ic«ioti  is  easv  ;  the  absence  of  a  pro-

of  the  raiicoua  membrane,  in  conaei|uence  of  the  contraction  of  tho  cico-

and  presents  ncillicr  "lands  nor  epithelial  covering.  If  there  has  been 
during  life  a  layer  of  epithelial  cells  over  the  spot,  they  are  no  longer

rewUly  become  tho  seat  of  a  new  ulcerative  process  (Cruveilhior). 

Fatal  termination  of  the  lesion  inny  bo  induced  by  hemorrhage  or  by

cially  perforation,  are  incomparably  more  frË(|Uenl  in  aimple  ulcer  than 
in  canc«r  of  the  stomach. 

Wliat  is  the  cause  of  simple  ulcer  of  the  stomach  ?  It  ia  rea.ionabIe  to 
refer  it  to  a  molecular  'teath  of  the  tissue,  to  embolism  or  to  tlirombosiit  of 
one  of  the  vessels.  Such  is  the  hyjioiheais  which  has  been  advanced  by 
Virchow,  and  which  is  supported  by  a  number  of  clinical  observations 
and  experimental  researches.  On  the  other  hand,  ecchymoses  and  capil- 
lary «mboltsms.  when  they  accompany  ulcerations,  give  rite  to  a  very 
■npcrfieia]  mortification,  which  doos  not  involve  the  deep  tissues.  \Vc  may 
admit,  as  a  gen<;nil  law,  that  the  legion  is  cause*)  by  an  arrest  of  the  cir- 
eulation.  Atheroma  of  tlie  arteries  may  in  itome  cascA  be  recognised  as  a 
cauKe  of  ttic  trouble.  The  i[uality  of  fooil,  alteration  of  tlie  gastric  juice, 
Hiibstances  which  havi^  a  local  action  upon  the  stomach,  aa,  for  example, 
alcohol,  mercury,  etc.,  may  alao  enter  into  the  etiology  of  tliiit  disorder. 
An  uIc«ralion  once  establishe^î,  we  mav  suppose  that  the  continuous  action 
of  the  gastric  juice,  together  uith  sclerosis  of  the  small  arteries,  which 
diminishes  the  aMux  of  blood  and  conse>|UcntIy  the  nutrition  of  the  purt. 
is  sufBcient  to  prevent  complete  cicatrisation,  and  to  occasion  the  accident» 
observed.

record  scvcml  observations  of  ulcer»  and  of  hy|wrlropbicd  thicltcninjç  of 
iralls  of  th«  stomach  which  they  connect  with  syphilis.  Hut  most  of  the 
these  reconU  are  indeliiiitc.  Thitt  is  not  so  of  m  ca*e  reported  by 
Klebs,  where  there  were  nicer»  of  the  stomach  ami  intestine  associated 
with  gummata  of  the  liver.  We  ourselves  have  seen  a  case  of  syphilitic 
tamor  of  the  stomach  accompanied  by  very  characteristic  gummata  of 
the  liver. 

Alen;;  the  lesser  curvature,  and  in  the  nci);bborhood  of  the  pylorus, 
the  mucous  membrane  of  the  stomach  presented  prominences  of  flattened 
nmbilivatcd  tumors,  from  2  to  »  centimetres  in  diameter.  Over  them 
tbc  mucous  membrane  was  prescrvcil,  but  it  was  thin  and  adhervnt. 
Id  a  vertical  section,  tlic  thickened  ami  altered  sutiuiucous  tissue  pre- 
sented a  thickness  of  8  to  V2  millimetres.  This  elevation,  formed  of 
tliickened  submucous  tissue,  was  perfectly  distinct  from  the  muscular 
layer  sttitated  below. 

The  muscular  layers  were  normal,  or  scarcely  at  all  thickened,  while 
the  anhmucoufi  connective  tissue  was  hypcrtropbied.  Thi»  connective 
tissue  was  of  fibrous  consistence,  very  dense,  and  yielded  no  juice  by 
Benping.     Its  color  was  yellow. 

The  pylorus  was  constricted.  There  were  no  adhesions  of  the  stomach 
witJi  the  liver;  but. at  the  lesser  curvature,  the  peripheral  cellular  tissue 
was  adherent  to  ihe  indurated  lymphatic  -glands,  and  there  was  a  hard, 
white,  stellate  cicatrix  scon  upon  the  «urfaee  of  the  stomach. 

On  microscopic  examination,  tbe  };landuUr  layer  was  studded  with 
erect  and  oblique  villous  or  papillary  elevations.  These  villosities  con- 
sisted of  hypertrophic  granulations  "f  tbe  coniioctiw  tissue  which  anr- 
rounds  the  tubitlar  glands.  The  fçlands  were  sepiirated  from  each  other

leaves  iir)  doubt  of  the  syphilitic  nature  of  the  neoplasm.  It  enabk«  « 
to  understand  and  to  acknowledge  at  the  aame  time  the  existence,  in  Ifat 
stomach,  of  ulcerations  of  tlio  same  kind. 

In  this  same  case,  the  lymph  glands  of  the  lessor  curvature  were  vtty 
large,  white,  and  infiltrated  with  a  lactescent  juice.     The  juice  wt™ 
freshly  examined  contained  lymph  corpuscles  and  swollen  endntliernl 
cells,  some  in  n  state  «f  fatty  degeneration.    Tliin  sections  of  these  lviiip*i 
glands  showed  the  lymph  canals  extremely  dilated  and  everywhere  filW 
with  very  large  and  more  or  less  spherieul  endothelial  cell».    The  rociiiA' 
lary  tissue  also  presented  these  large  cells  in  its  me«hes.     The  s»n** 
alteration  also  existed,  but  in  a  less  pronounced  degree,  in  the  rcticnlnic*^ 
tissue  both  of  the  follicle  and  follicular  cords,  and  there  was  alsi»  a  rer^

The  hi'onchial  glands  bad  undergone  the  saioe  alteration,  and  the  retm*'

were  nianit'ested  by  a  chronic  lymphangitis  of  the  auperficiai  and  deep

at  the  cardiac  end.  They  have  a  ^reat  tctitcncy  to  extoiul  upon  the  ad-

Carcinomatous  growths  begin  in  the  submucoiu*  li«»uc,  and  in  the  glandular 
layer  of  the  elomnoh.  L'])»ti  a  vertical  «oction  il  t*  «evn  that  Die  glan>

scraping  tlie  surface  with  a  scalpel  ire  obtain  a  milky  Juice.  Micro- 
scopic examination  of  tliin  seclioika  through  the  morbid  growth,  prove» 
that  the  submucous  tissue  already  shows  carcinomatous  alveoli  filled 
with  cells  of  a  new  formation,  whilst  the  glandular  layer  exhibits  its 
glands  much  lengthened  and  filled  with  cylindrical  or  cubical  cells. 
Thti  connective  tisKue  which  separate»  the  glands  contains  a  large  num- 
ber of  embryonal  cell."  between  it*  fibn-s.  From  tlii»  interglundular 
embryonal  tissue  may  grow  prolongation.*  which  extend  lieyond  the  neck 
of  (he  glands  in  the  form  of  papillary  vegetations.  This  formation  of 
papillary  vegetations  is  common  to  all  new  formations  in  th«  mucous 
membrane  of  the  stomach. 

In  tho  neighborhood  of  tbe  cancer,  the  mucous  membrane  is  iisiuilly 
altered;  itiared  or  violet,  somciimea  softened  or  mammiilated,  and  it 
presents  the  indications  of  chronic  inUammadon,  frr<|ucntly  witli  intense 
liigmentation.  Small  retention  cvjts  of  the  glands  arc  also  often  met 
with.  It  is  verj'  rare  to  find  the  mucous  membrane  iu  a  bcaltliy  condi- 
tion around  the  canccrou«  nmlule. 

When  tliere  is  uU-eralion.  tbe  ulcor  is  of  variable  eÎEc.  If  it  îa  seated 
at  the  pylorus  it  may  have  the  form  of  a  ring.  l"lcemtion  mav 
momentarily  re-establish  the  coime  of  llie  f<Mid  which  bad  been  arrested 
by  the  contraction  of  the  pyloric  orifice.  The  edges  of  the  ulcer  are 
olevatmi,  and  sometimes  loosened.  lU  bottom  is  habitually  fundus, 
bloody,  and  covered  with  detritus  ;  or  if  the  whole  cancerous  growth  ia 
nearly  destroyed,  the  muscular  tissue  ie  exposed  or  partly  destroyed,  or 
tliere  may  even  be  a  peri'onition. 

Perforation  U  incomparably  more  rare  in  those  tumors  than  in  simple 
ulcer.  The  muscular  tunic  adjuining  and  in  the  neighborbood  of  the 
tumor  is  always  hypertrophied.  This  hypertrophy  may  extend  far  be- 
yond the  location  of  the  tumor,  it  nin.y  involve  the  whole  muscular  coat, 
as  frcpivnlly  happens  when  tbo  new  gn>wtb  affects  the  pylorus.

SuiLL  IsTESTiXB. — The  small  intestine  is  composoil  of  several  layers 
«r  tncmbrnncs  which  art-,  from  without  inwards  :  tiie  peritoncuto,  foniKd

«till  the  miicoiis  membrane.  It  is  the  lutter  which  wo  have  cs[>ecially  to

The  niucow»  membrane  of  Uie  ttraiil!  int««tin«,  conliniiou*  at  the  (lylorug

and  its  surface  ia  covered  wilh  villi  which  P'k-  SSf- 

give  t«  it  a  vptvely  sfipearance.  These  villi 
are  extremely  numerous  in  the  duoiienum 
MkI  jejunum  (jiU  to  !tO  to  the  square  line)  ; 
they  dimiuixh  in  numlier  in  the  ileum  (40 
to  70).  Throuj;hi>nt  the  whole  extent  of 
Uie  small  Intoiitine  the  mucous  memhmne 
contains  tuhular  glands  or  l.ioberktlhnian 
follicles,  which  have  some  resemblance  to 
those  of  the  stomach.  Moreover,  in  the 
upper  portion  of  the  duodenum,  racemose 
{glands  or  glands  of  Brunner,  somewhat  simi- 
tar to  the  salivary  glands,  are  found.  In 
addition  from  one  end  of  the  small  intestine 
to  the  other,  closed  follicles  are  met  with; 
they  may  ho  i»oliited  (solitary  follicles)  or 
agiuinated  (I'eyer's  patches). 

The  connective  tis-tue  of  the  miicou«  mem- 
brane is  a  reticulated  ti.-i.iue  (Ili^),  whether 
it  ia  located  in  the  papilln;,  hotweeu  the

which  surrounds  them.     The  portions  of  the   mucous   membrane  tba 
thickened  at  one  point  may  form  an  elevation,  which  later  may  tiecaoH^ 
pedunculated.     Thus  are  produced  those  papillary  glandular  polypi  so

tremity, filled  vith  cylindrical  cells,  ha»  divided  into  two  oc  three  cule-

We  believe  that  the  previously  describeil  glandular  foUicleH  generally 
occnpy  tbe  place  of  the  destroyed  closed  foUioleB.  They  have  the  itame 
locution,  the  same  relalions  with  the  glandalar  layers  and  the  superficial 
mnMcnUr  luyer,  and  the  same  form  as  the  closed  follicles.  Moreover,

points  and  that  there  are  larj^e  space-i  bounded  by  areas  of  the  reticulum. 
Should  these  softened  portions  of  the  follicloa  break  open  and  communi- 
cate with  the  surface,  we  would  have  the  eavities  which  have  already 
Iwcn  ilcscribud;  cavities  which  would  soon  be  fitted  by  the  intestinal

Upon  ihcflo  cicatrices,  where  the  iniicoua  membrane  h&n  never  «ntirely 
Tc-fortiiL-'l,  polypous  oicreaceiices  »rc  often  found,  coiisUtiiig  of  fibrous

The  diarrbiea  i«  not  always  constant  ilnring  the  whole  course  of  the

CnoLBRA. — Cholera,  an  infectious  disease  in  wbicli  the  most  of  the 
or<:an8  are  altered,  U%»  for  its  fîrit  mitni Testation  the  signs  of  an  inles* 
linal  catarrh  whiuli  correspond  to  a  pathological  state  of  the  smtill  inlea- 
tiiie.  Thi»  is  why  the  pathological  anatomy  of  this  disease  bas  its  place 
in  the  chapter  on  the  intestines. 

.\t  the  a\itop«y  of  paticntit  who  succumb  in  the  stage  of  cyanosis,  we 
find  the  ^mall  inte.itine  very  much  cons^itted  throughout  its  length,  but 
|iarticu1arly  in  the  ileum.  The  mucouii  membrane  prenentu  a  pink,  lilac, 
or  red  color.  On  account  of  the  fulne^  of  the  capillaries  an<l  small 
veins,  the  summits  of  the  foMa  are  especially  colored.  The  mucoiH 
membrane  is  thickened,  turgid,  and  œiiematous  ;  the  intestine  îh  dis- 
tendcd  hy  a  large  <|nantity  of  a  whitish,  cloudy,  odorless  iluid.  in  which 
are  Huspended  small  opaipie  flakes  (rice  bodies). 

The  epithelial  coverings  of  the  villi  and  of  the  mucous  membrane  des- 
quamate afWr  death,  but  an  examination  of  the  etooU  during  life  does 
not  indicate  that  there  is  an  abundant  loi«  of  the  epithelium  during  the 
choleraic  att.ick.  The  chnidine^t  of  the  fluid  i^  due  not  only  to  lymph 
cells,  but  more  particularly  t^  the  presence,  in  larj^e  numbers,  of  proto- 
organiams  like  those  met  with  in  putrefying  fluids. 

llajem  and  Raynaud,  in  the  last  epidemic  of  cholera  (1863),  verified 
the  ohMrvatioM  made  by  Pacini.  Oavaine,  etc.,  of  the  presence  of  in- 
Tuaoria  in  large  qitantity  in  the  stools  of  cholera,  but  without  finding, 
among  the  ten  rarietics  at  least  which  were  present,  any  which  are  spe- 
cial to  cholera.  There  were  varieties  of  three  kinds:  bacterium,  vibrio, 
bactcridiiim  (Daraine). 

We  find  besides  collections  of  spores  in  great  number?,  of  themselves 
alon*  fonning  the  greatest  part  of  the  wbiti:<h  flakea  ;  they  ]>robably  cor- 
respond to  the  imcrni^iiTHt  of  tiermau  nulhora,  and  do  not  apjiarcntly 
differ  from  yeast.  All  these  proto-organi-tms  exist  in  the  atooU  from  the 
first. 

The  specific  gravity  of  the  atoola,  compared  with  that  of  tlie  intestinal 
fluid  obtained  by  the  process  of  Thiry,  is  very  low;  it  runs  from  1.004, 
l.OOii,  up  to  1,013  in  certain  cases. 

Chemical  analyns  shows  that  organic  matter  is  not  very  abundant 
(Bccqncrcl).  We  find  urea  or  its  decomposition  product,  carbonate  of 
amraoTiia  ;  it  is  this  which  renders  the  fluid  alkaline.  The  proportion  of 
the  alkaline  chloride»  and  salts  is  sensibly  the  same  as  in  health.  The 
eholeraie  stools  a)iproach  very  closely,  in  chemical  analysis,  to  the  fluid 
ObUined  by  A.  Moreau  in  the  expérimenta  above  cited.

nective tisiiue  ;  it  is. not  limited  lo  the  small  intestine,  but  may  extend  the 
whole  length  of  the  intestinal  canid  from  the  pvlorus  to  the  aou3  ;  it  exists 
als'i  in  a  variable  amount  in  the  intestinal  villi.  The  ;;Iands  of  Lielwr^

(in  part  a  p(>*t-mortem  change),  aud  they  arc  oluin  distended  by  luaflus. 
The  bloodvessels  which  exist  id  the  supertioial  part  of  tlie  mucous  mcffl- 
brauc  are  <list«-iided  with  bluod,  and  their  nulls  are  in  an  embryonal  con- 

bdition.     The  siimc  is  remarked  of  the  vessels  of  the  submucous  tissm-. 

The  lymphatics  are  tilled  by  round  wiU  or  by  their  swollen  endutho-

In  a  more  advaiicttd  »tage  of  tiie  lesion,  when  the  autopsy  is  made 
during  the  period  of  revuUioii,  we  sometimes  find  follicular  ulccn 
situated  at  the  location  of  the  isol.ttt-d  follicles  or  at  the  seat  of  Pever's^ 
jialchi-s.  The  mucous  membrane  is  less  coi));ested,  except  ,t)iat  at  ccrtaii 
points  a  («rsistent  hypersemia  is  observed,  and  sometimes  u|H>n  tiie  to| 
of  the  folds  of  the  small  intestine  there  arc  even  superficial   ulocn.

Tlic  phytiical  characters  of  the  intestinal  contents  are  entirely  dilfereat 
from  those  observed  in  the  first  stage.  There  is  no  longer  a  rice-water 
fluid,  as  in  tla-  fimt  peri'^d  ;  tlie  intestinal  Huid  Is  colored  by  bile  ;  of 
it  is  strongly  ling<^d  by  blood.  The  large  intestine  contains  solid  matut 
or  a  diarriiucic  lluid. 

Altérations  of  the  blood  are  noted  in  a  very  high  degree  during  tba 
fîr<t  or  algiil  stage.  The  blood,  from  loss  of  «eruni,  has  beeome  so  thick 
that  it  does  not  circulate  freely  or  does  not  How  at  all.  Krom  (his  Iom 
of  scrum  it  results  that  the  number  of  red  blood  globules  is  rclatiwly 

iiBiuch  increased,  and  the  white  corpuscles  are  increaaed  in  the  same 
pordon.     The  red  disks  are  viscous  ;  a  large  number  of  them  pre«ent  i 
volume  much  less  than  normal.     There  do  not  appear  to  be  any  pnt»  j

TïPnoT»  Fevub. — The  intestinal  lesions  of  typhoid  fever  «re  Incatud 
in  tlie  lower  part  of  the  small  intestine  :  it  is  seldom  that  they  involve 
the  large  intestine.  Four  stages  may  be  recognized:  l«t,  the  cutarHial 
period;  2d,  the  period  of  swelling  and  ulceration  of  I'eycr's  patches; 
Sd,  the  period  of  abatement;  4th,  the  period  of  cicatrization.  These 
four  periods  correspond  more  or  less  ehiscly  to  the  four  weeks  during 
which  a  typhoid  fever  of  medium  intensity  lasts. 

1st.  In  the  fir!<t  period,  which  u^iuilly  lasts  four  or  five  days,  the 
mucou-i  membrane  is  crtug.'*ted,  and  it  weeretes  a  grenier  or  less  quantity 
of  diarrbiral  Unld  ;  the  closed  follicU's,  b"lh  the  isolated  and  the  agmi- 
nated,  especially  those  of  the  lower  part  "f  the  ileum,  are  swollen  from 
the  beginning.  The  isolated  follicles  form  small,  pinkish,  semitranspa- 
rent,  pearly  prominences  ;  the  l'eyer".s  patches  are  tuntelied,  and  form 
slight  elevations, 

2d.  In  the  second  period  the  hypertrojihy  of  the  follicle*  and  of  the 
Peyer's  patehcs  increases.  At  auto]nies  made  on  the  lifth  or  sixth  «lay 
of  the  disease,  wc  have  seen  the  isolaied  follicles  looking  like  hanl, 
prominent,  conical  nodules,  fi^om  ;i  to  4  millimetres  in  height,  while  the

We  for  microBcopic  examination. 

At  autopsies  made  twcniy-four  hours  after  deatli.  the  cylindrical  ci-lls 
of  the  surface  have  been  macerated  into  an  opa-iuc,  purifortu  fluid  which

aUo  are  to  he  found  in  tliesc  scrapings  numbers  of  large,  swollen,  spheri* 
oal  or  polygonal  or  flat  cells,  with  a  granular  protoplasm,  and  one,  twa^  J 
or  throe  ovoid  nuclei.   These  large  cells  are  nothing  else  than  the  swollen  I

modification  of  form  is  due  to  the  fact  that  the  tissue  of  the  villi  ts  infiM

Such  is  the  structure  of  the  hypertrophied  patches  in  typhoid  fovcr  ;

(rilli,  closed  follicles,  and  deep  adenoid  tissue)  and  of  the  connective

During  tlii.i  second  period  of  the  diwase,  the  ulceration  always  begins 
in  tJie  patches  and  follicles  nearest  to  the  ileo-ciecal  valve. 

In  the  hard  patches  it  is  easy  with  the  naked  eye  to  uee  the  process 
of  ulceration  by  mortification  of  a  more  or  leas  extensive  portion  of  an 
isolated  follicle  or  a  Poyer's  patch.  It  is  the  most  elevated  part  of  die 
follicle  or  I'eycr'a  patch  which  first  mortifies  and  assumes  a  yellowish 
tint,  due  to  the  imbibition  of  the  intestinal  fluid.  The  mortified  part  is 
soon  cut  off  from  llic  rest  of  the  morbid  tissue  by  a  narrow  border, 
then  by  a  furrow,  and  it  is  subsequently  eliminated  in  $n>»ll  (moments. 
Almtglide  of  one  of  thc»e  small  eschars,  slill  in  viVu,  oihcnt  are  seen 
which  are  almost  completely  expelled,  leaving  in  their  place  an  ulcer,  (ho 
bottom  of  which  is  filled  up  little  by  little. 

The  liard  patches  »ucce««ively  present  new  points  of  sloughing,  and  a 
total  ulceration  is  thus  eRbcted  in  small  islands  which  are  attacked  one 
after  anoUier. 

The  isolated  follicles  present  at  the  commencement  of  this  ulcerative 
process  a  small  slough  upon  their  most  prominent  part.  The  slough  is 
thrown  olf,  and  there  results  an  ulcer  which  occupica  solely  the  centre  of 
the  follicle  and  which  progressively  spreads  by  tno  invasion  of  the  whole

which  continues  during  the  fourth  week.  At  the  bordera  of  the  ulcer 
there  commeDceK  an  irregular  formation  of  t^uimlutivc  tisfluc,  which  little 
by  little  spreads  over  the  iilcenited  surface.  As  this  tissue  condcitMS 
the  bonlers  of  the  ulcer  appritnch,  and  the  cicatrix  form».  But  complete

cicatriïalion  the  cicatricial  tiitsue  becomes  pigmented  almost  conntanily, 

^and  this  pigmentation  remains  for  years. 

B  Microaeopic  examination  of  the  cicatrices  shows  that  all  the  tinsue  pre- 
viotuly  attacked  by  ulceration,  thai  is  to  say,  the  whole  surface  of  tlie 
inucoua  membrane  of  the  patches,  is  replaced  by  a  connective  tissue  with

round  cells  interposed  between  them,  'i'here  is  here  no  vestige  of  the 
closed  foltictcs,  of  the  glands,  or  of  the  villi.  The  vessels  remain  dilated 
with  embryonal  walls,  and  aro  often  «urrounded  with  black  pigment.  If 
in  the  cicatrices  we  aonaetimes  find  the  remains  of  a  few  villi  or  glands, 
it  is  becauM  nil  the  ti.-<.tiie  of  the  nmcou»  membrane  had  not  been  attiicked

may  not  contain  âuid.  Under  other  circumstance»,  it  contains  a  seniiu 
fluid  which  is  transparent,  pink,  or  even  dark-red  and  aaogiiinolenl, 
and  in  which  tal^e  membranes  exist.  The  serous  coat  of  the  intestine 
is  almost  normal,  or  it  is  intenselv  red,  as  in  acute  peritonitis,  when  it 

Ç resents  a  whitish  opacity  or  false  membranes  and  vascular  papil!»). 
he  study  of  the  condition  of  the  mucous  membrane  in  such  cases  has 
not  been  tboroughly  made,  but  it  is  probable  that  it  also  is  attacked  by 
a  more  or  less  intense  inflammation.  l;^malI  abscesses  have  been  found 
between  the  intestinal  tunics.  If  the  hernia  is  not  reduce<l,  this  infiaoi- 
mation  of  the  sac  niul  of  the  intestine  terminates  by  fibrous  adhesions 
between  the  two,  and  by  thickening  of  the  sac  and  of  the  coats  of  the 
intestine. 

In  atrimi/ulaUd  Iterniti,  the  color  of  the  serous  surface  of  Uic  intestii 
is  of  a  darker  red  than  in  intlammalion.     It  is  ecchymotic,  brown,  : 
preaching  violet  or  black.     The  stranjtulated  loop  is  tense,  much  lar 
than  normal  ;  later,  when  perforation  or  ^ngrene  threatens,  there  nny  ' 
be  collapse  of  the  included  gut. 

The  serous  covering  is  stretched,  and  presents  eroeiona  at  the  seat  i 
strangulation.  The  subserous  cellular  tissue  is  Ui«  scat  of  Mood  iat 
trations  and  ecchymoses.  Later,  the  serous  membrane  is  covered  by  a 
fibrinous  exudation,  and  the  sac  contains  an  inflammatory  fluid  which  is 
oolore<l  by  blood.

Totvinz  all  tlie  slructures.  Tiio  much  congested  villi  are  aKoUen,  soft- 
ened, friable,  and  shortened;  tiicv  Qiaj-  even  be  united  toother  b;  a

are  hyportrophted,  intiltmtud  wi^i  tlitid,  and  ulcerated  at  the  centre. 

The»  lesions  are  espucially  pronounced  at  tlic  ttcat  of  slraoRulatioii, 
and  particularly  at  the  junction  of  the  Htranj^lated  loop  with  the  supe- 
rior end  of  the  int«atiiie.  'i'hc  latter  it  distended  with  inlc«tinal  matter, 
especially  \>j  gas.  The  iiitiannimtiun  of  tlie  mucous  membrane  and  of 
the  serous  covering  spreads  to  the  upi^r  end  of  Ibe  gut,  ami,  in  certain 
oases,  there  results  a  general  jieritonitis.  The  lower  erul  of  tlic  interline 
Ï»  diminished  in  calibre,  contracted,  and  it  also  is  ttie  seat  of  hitlammatorjr 
levions  of  the  mucous  membrane  and  serous  coat  nhich  are  le»s  intense 
than  upon  the  superior  ond  of  the  gut. 

When  the  coDBiriction  persists,  the  impodimoot  or  the  arrest  of  the 
circulation  at  tbc  point  of  compression  dotormines  a  progressive  de. 
slniction  of  iJie  intestinal  wall,  which  is  effected  bj  a  sort  of  molecular 
elimination  at  the  [Miint:*  I'-f  constriution.  This  destruction  is  secured 
irititout  the  gangrene  exk-nding  beyond  the  «ubitions  of  continuity;  the 
tunics  appear  ns  if  they  bad  been  cut  niecbauically  ((iossehn).  The 
alteration  begins  at  tlie  superficial  layer  of  tlie  mucouii  membrane,  and 
progressively  invades  the  submucous  tissue,  the  softened  muscular  tunics, 
and  finally  the  serous  membrane  (Nicaise).  Save  in  exceptional  cases, 
section  eilends  from  within  outwards.  The  perforation  may  be  very 
small  and  diflicuU  to  see,  or,  on  the  contrary,  it  may  involve  the  greater 
part  of  the  circumference  of  the  intestine. 

Another  termination  of  intestinal  «trutigulatioii,  much  more  rare  than 
tbc  preceding,  is  t!''"i^'''^"<'>  which  may  appear  in  supcrficiai  spots,  or 
wliich  may  allect  at  once  all  the  coats  of  the  intestine.     The  gangrene 

ly  be  located  &t  any  {loint  irhalever  of  tlio  strangulated  loop. 

The  le4toiu4  'if  the  intestine  which  are  observed  in  strangulation  of  the 
ileum  by  bridles,  by  rings,  by  the  accumulation  of  fecal  matter,  by 
[invagination,  etc.,  are,  generally  speaking,  the  same  as  those  just  de- 
Hribcd  of  hernia.  A  strangulation  by  invagination  may  terminate  hy 
the  expulsion  of  the  gangrened  intestine,  and  a  union,  end  to  end,  of  the 
intestine  ;  or  it  may  end  in  perforation,  peritonitis,  pernicious  adhesions, 
and  almost  aUays  cicatricial  contractions  of  the  intestine.

TcBBnctiL09ls  OP  THE  IsTRPTlSB. — Tlie  tuherculous  leitons  of  the 
intestine,  like  those  of  typhoid  fever,  hare  their  preferred  seat  in  the 
lower  part  of  ttie  small  intestitie,  but  they  do  not  remain  confined  to  lliat 
region  ;  thej  generally  extend  over  a  wide  extent  of  the  ileum,  the  jeju- 
num and  larger  intestine,  including  the  reoluio. 

These  lesions  arc  char»cterizod  by  tiiberelo  «ranulps  and  caseous  and 
ulcerative  inflammation  of  the  isolated  and  a;;mi!iai«d  lymph  follicles  aa 
well  as  bv  inflammation  and  dostructioti  of  the  surrounding  connective 
tissue.  From  the  mucous  nieintiranc,  which  is  their  point  of  origin,  thej 
extend  to  the  deep  coats  of  the  intestine,  and  involve  the  submucous coik 
nectivc  tissue  nmi  the  lymph  vessel*  of  the  inlc«tinv.  as  well  as  those 
which  lead  from  tiic  intestine  to  the  lymph  s;lanil»  of  the  mrsentcry. 

We  deaeribe  together  the  lubi-rcle  grannies  and  tJie  tuberculous  in- 
flammations of  the  clo;i«d  f'olliclcii,  hecauiie  these  two  varieties  of  the 
same  process  are  almost  constantly  seen  associateil  with  the  luberculout 
inflammation»  of  the  follicle,  the  tatter  sometimes  even  preoodtng  tlie 
tubercles. 

Tubercle  granules  of  the  mncouH  membrane  of  the  intestine  begin  ai 
small  round  ie  mi  transparent  grains  which  project  above  the  surface,  «mt 
which  mav  be  located  in  the  connective  tissue  around  tlie  culs-de>s3M:  of 
the  glands  of  Licbcrkiiho,  or  in  tlie  connective  tissue  of  the  villi, 

Wlien  a  thin  section  passing  tlirough  such  superficial  tubercles  is 
examined,  we  see  two.  three,  or  a  greater  number  of  villi,  with  small 
round  cells  filling  their  rcticntnted  tissue.  These  villi  are  united  to- 
gether at  the  base,  while  they  are  still  separated  at  their  free  extremity. 
They  are  thickened  as  wclf  at  their  free  extremity  as  in  the  points 
vfhero  ihey  are  fused  together.  From  their  nniim  and  their  infiltration 
bv  small  cells  there  results  a  solid  excrescence  of  the  superficial  portion 
of  the  mucous  membrane,  having  to  the  naked  eye  and  under  tlie  micro-

VAK(a'LAR  Ti'MORB. — Dilatation  of  the  veins  or  phlebeclacy  is  not 
infreipient  in  Ibe  large  intestine,  especially  in  the  hiemnrrhoidal  plexus 
aroniid  the  anus.  Varices  are  often  found  in  the  smalt  intestine,  form- 
ing an  elevation  of  tlie  mucous  membrane.  The  causes  of  these  dilata- 
tions are  all  those  which  determine  a  blood  stasis  of  the  different  branches 
of  the  portal  vein  :  cirrhosis  of  the  liver,  iliseasc  of  the  heart,  abdominal 
lors,  increase  in  siie  of  the  uterus,  efî'ort^  of  parturition,  constipation, 
the  efforts  in  defecation,  etc.,  all  eausis  which  impede  tlic  course  of  the 
blo«<t  in  the  hicmorrhoidal  veins. 

Hn.-morrb«ids  consist,  at  the  commencement,  in  a  simple  dilatation  of 
the  veins  at  the  bonier  of  the  anus,  and  which  form  there  a  «li^bt  pro- 
jection, .^t  the  same  time  the  vt:in!«  .tituated  hencath  the  rectal  mucous 
membrane,  above  and  below  the  spliiiicter,  are  dilated.  Later  tlie^e 
dilatations  increase  in  ttÎKe  and  become  distended  under  the  form  of  little 
lumps  by  the  etfarla  at  defecation.  Rupture  at  some  point  of  the  dilata- 
tion, consequent  hemorrhage  and  catarrhal  irritation  of  tlie  mucous  mem- 
brane of  the  lower  part  of  the  rectum  are  the  usual  serjuctffi.  The  cellu.

are  only  a  litllo  more  rcji;utarly  di«tpoRed  than  in  the  fltomach.  Thew 
polypi  may  be  the  cause  of  an  invaj^ination  of  the  lar;;?  intostine.  When 
they  project  externally  throujjh  the  anal  ajierturc,  that  part  of  the  in-

the  intcstinu.  become  flaUciicd  and  pavement  shaped,  and  the  surface  of 
tlio  jNjIvptis  assumes  all  the  characters  of  the  skin,  except  in  remaining 
red.  This  peculiarity  is  observed  of  all  fonns  of  polypi  which  project 
extomally. 

LviiPHADiixoMATA  of  tho  stomach  and  intestine  have  be«n  studied  in

more  ntr«  tliao  tliatof  the  stomach,  but  when  itoccura  it  preMnts  entirely 
the  same  charactors  aa  when  found  in  the  aiooiaoii.  It  is  often  secomlarj 
to  carcinoma  ori;;iiiatinf;  in  neighboring  tissues,  the  peritoneum,  the  aterufl, 
the  bladder,  ete. 

Tlie  rc;;ioTi8  most  freiiiicnti;  alTected  bj  carcinoma  are  the  rectum,  the 
hepatic  (lortioii  of  the  traTi»ver»o  colon  ;  the  c»cam,  the  duodcuuiQ,  an<l 
J4'Junum  are  very  rarely  attacked. 

AWrMw»  and  tn^yhnl'i'l  are  met  with  in  the  rectum,  tlic  firet  more 
freiiuently  than  die  second.  The  tumor  may  be  developeil  in  the  ricinity 
of  the  sphincter,  or  eight  or  ten  centiiiiittroH  above  it.  Tlie  growth  MaT\» 
in  ttie  Aubinucoua  connective  liiwue.  The  .«ubmucouA  infiltration  •.-vcendit 
in  an  annular  form  completely  around  the  circumference  of  the  inteiitine, 
and  occasions  a  eonstrictton. 

The  grannlatiog  appearance  of  the  mnoous  membrane,  ita  ulceration, 
tbe  extension  to  the  deep  layer,  the  hypertrophy  of  the  muscular  coats 
of  the  rc«tiim,  tbc  infection  of  the  lymph  glands,  are  in  every  respect 
comparable  to  the  le«ions  in  carcinoma  of  the  stomach. 

Authorn  record  the  frC([uency  of  colloid  carcinoma  of  the  rectum. 
It  is  certain  that  tumors  havinj^  a  colloid  aspect,  are  not  infrci|uent 
in  -the  rectum  and  other  parts  of  the 
intestine,  but  we  chould  not  consider 
tliat  every  colloid  tumor,  with  large 
alveoli  filled  with  gelatiniform  mat- 
ter, is  carcinomatous.  As  wo  have 
already  seen,  cj/linttrirttl-i'elUd  epi- 
theliomit  may  sufter  a  colloid  dugene- 
ntion. 

The  cancerous  tumor  may  ulcerate, 
and  in  this  way  an  ohntniciionof  the 
lumen  of  the  gnt  may  be  partially  and 
momentarily  removed  as  with  similar 
tumors  of  the  pylorus,  and  the  ulcera- 
tion may  cauao  a  perforation  of  the 
intestinal  wall,  an  accident  which  hap- 
pens more  rarely  than  in  thy  stomach. 

Occasionally  carcinoma  may  show 
it^-lf  in  the  intcBtinii  under  the  form 
of  multiple  tumors.

the  prismatic  spacer  formed  between  the  lobules,  and  ponctrate  the  latter 
al  their  surface,  so  thut  each  lobule  receives  its  blood  from  four  or 
fivo  branches  of  the  portal  vein.  In  the  same  intcr-lobolar  prismatic 
«paces  which  receive  the  portal  vein,  run  branchies  of  the  hepatic  artery 
and  inter-lohulnr  biliary  canals  surrounded  by  connective  ti>uu«  in  con- 
tinuity with  the  eapiulo  of  (rlisaon.  The  capilUricH  of  tlie  hepntie

peripliory  of  the  lobulea,  where  they  anaotoroofle  with  the  caiiilUries  of

The  lobules  are  in  contact  one  with  the  other,  separated  only  by  the

granules,  nliich  may  be  colored  by  tincture  of  iodine.  During  digestion, 
tiie  cells  «t  the  periphery  of  the  lobule  contain  fat. 

The  cella  do  not  possess  a  separate  membrane,  but  thuîr  granular 
ibsiance  is  densei-  at  the  surfncv  of  the  biliary  canuts,  and  t'orms  a 

in  cuticle,  scrv-ing  as  a  wall  to  the  canals. 

OoiMidcrcd  in  their  mutual  relations  in  the  lobule,  the  liepatio  cells, 
toconlinji  to  Kberth,  ap|>t'ar  to  form  series  or  cohimns  radiating  from  the 
centre  to  the  periphery,  nnd  una«toinojting  tmntiveraely. 

Tlieic  network!*  or  trahtcuUv  ;j'  /iffiatir  rtU»  are  eompared  to  the  lubes 
containing  hepatic  celU  which  are  met  with  i»  some  animaU  (fishes  and 
reptiles).  This  apjwarance  of  trabecule  ia  due  (o  tlie  general  conlÏKura- 
tion  of  the  capillary  network,  as  demonstrated  by  Hiring  and  KùUîker. 
In  man  and  the  higher  mammiferro,  there  is  no  membrane  comparable  to 
a  glandular  sac  which  incloses  the  hepatic  cells  and  separates  then  from 
the  capillaries.  In  the  rabbit  (liiSrin):).  the  bepalic  cells  adhere  to  the 
eapillariot,  aiuL  do  not  scparat«  from  them  nht-n  a  piece  of  the  liver  is 
placed  in  alcohol  or  chromic  acid,  rcngenU  which  cause  the  elements  to 
shrink.  In  man  and  <lo^s,  the  hardening  notion  of  these  âuîds  sepa- 
rate» the  cells  from  the  wnlU  of  ibo  capillaries. 

The  hepatic  lobule  abould  liien  be  considered  simply  as  a  (wntinuotis 
of  cetU  channelled  by  a  capillary  network,  the  cells  being  arranged 
koconling  to  the  form  nf  the  vascular  meshea. 

Tlie  biliary  veaaels  have  their  origin  in  the  hepatic  lobule  by  a  net- 
work of  fine  eanalicnli.  which  form  narrow  meshes,  and  are  in  contact 
vlth  all  the  hepatic  cells.  This  network  connects  with  the  intvr-lohular 
biliary  canals  which  ui:com]mny  the  branches  of  the  portal  vein.

Therefore,  excepting*  traumatic  affectîona,  it  uay  be  aaid  that  tbe  Si*kty 
majority  of  hepatic  aSectJouB  are  secooiUrj  to  otlicr  general  or  local' 
affections. 

In  warm  countries,  where  dcranj^t'menta  in  the  functions  of  the  liver 
arc  f)0  common,  the  more  intense  follow  intermittent  fever,  yollow  fever^ I 
dysentery,  alcoholic  cxccMes,  etc.  In  our  climate  thoy  are  secondary  to  ' 
intermittent  fever  and  dysentery,  but  arc  always  lcs«  serious  than  in  trop-

and  to  purulent  infection;  or  they  are  occnsioneil  by  aflecliuns  of  the 
biliarv  oniials,  the  lobules  being  sometimes  secondarily  affected.  Finally, 
parosiU-H  may  aUo  cause  secondary  diseases  of  tlie  liver.  Affection*  of 
this  organ  ar<^  found  to  be  altnottt  always  detitoro|>athic. 

In  order  to  have  a  general  idea  of  the  lesions  of  the  liver,  it  is  neoe**  i 
»ary  l"  study  the  anatomical  aheralious  which  its  eiemiMiiary  paruj 
undergo:  that  is.  first,  those  of  the  hepatic  cells  which    make  np  tbo  ' 
greater  part  ;  nuxt,  tb«  cellulo-vascular  tissue,  and  tinolly  the  biliary 
canaU. 

1st.  C^ngtr  in  ifiv  Ififpatip  Celle. — It  bos  been  Men  tliat  the  shape 
of  the  hepatic  cells  is  polyhedric  ;  that  they  onuiu  a  nucleus,  and  ex* 
ceptionatly  two  nuclei;  that  their  j^raiiular  protoplasm  mntaiiw  alW 
minouo  Hiid  glycogenic  granule.-*:  that  nnujctimes,  in  the  nomuil  state, 
they  are  pigmented  and  fatty  ;  but  under  t)io  iiilluence  of  the  »eveTa) 
morbid  stat<-it,  tlieir  constitution  is  greatly  moditied. 

Their  shape  is  very  easily  altered  by  pressure  ;  in  the  normal  condition 
Uiey  arc  frequontly  moulded  upon  a  cajrtllary.  by  one  of  their  ekeavated 
aurfaccs.  From  the  pressure  of  tumors  developed  in  the  liver,  the  cellsj 
may  he  tiattened  in  one  direction,  so  as  to  have  a  resemblance  to  con>^ 
nective  tissue  with  tamellu)  and  Hat  eclls,  like  those  of  the  internal  coat 
of  artortes  or  the  capsule  of  the  spleen.  :>con  in  profile  each  such  cell 
resembles  a  fusiform  cell  a  little  thicker  at  the  position  of  ib#  nucleus. 
The  hepatic  cells  assume  such  uu  appearance  when  comprenscd  by  Uie 
^ssue  of  a  gumma,  by  a  tubercle,  by  ft  scirrhoo»  iiodulo,  hy  a  hydatid 
cyst,  ct«.  All  the  cells  of  a  compressed  lobule  tukv  tlu^  saute  shape; 
this  results  in  the  entire  lobule  being  flattened  and  spread  out  around^ 
the  tumor. 

Ill  conse(|nence  of  the  softness  of  the  protoplasm  of  the  hepatic  cells, 
the  entire  liter  may  be  cbangeil  in  its  fornk  by  the  comturossion  of  an 
abdominal  tumor,  ur  of  au  effusion  of  fluid  into  the  peritoneal  cavity.

Kxtcnial  pressure  from  corwts  also  changes  the  normal  shape  of  tlic 
liver.  In  ihU  case,  tlie  baac  of  the  thorax  Wing  contracted  bj  th« 
constriction,  tlie  entire  liver  is  pushed  downwards,  ita  superior  earfac« 
bcvomea  anterior:  this  surface,  smooth  in  the  normal  condition,  is  in- 
tli-ntvd,  am)  presents  depresùons  corraB))onding  to  the  rib»;  the  inferior 
bonier  of  the  liver,  which  nixv  extends  below  the  faloe  ribs,  is  at  times 
turned  up  l<encAth  the  rib«  in  foltowiti^  the  uohvcxity  of  the  abdominal 
irftll.  riiosc  deformities  become  permanent  in  conscijuenue  of  the 
alTOpliy  of  the  lohule»  coniprc««ed  in  the  fuldx  of  the  hepatic  eurfscc, 
and  from  the  thickening  of  the  CApttule  of  (ilisson  at  the  mme  points. 
Similar  defomiiticH  are  very  fre<|Uont  in  old  [lersons,  in  whom  the  back 
lit  arched,  and  in  whom  the  inferior  bonier  of  the  thoracic  csvity  com- 
presses the  anlerior  surface  of  the  liver. 

The  sliape  of  the  cells  ia  also  frequently  modified  by  blood  preasure, 
sa  in  diseases  of  the  heart  an<l  Whji^  nith  increased  blood  pressure  in  the 
rij*ht  auricle.  an<l  consci|uently  in  the  inferior  vena  cava.  The  pressure 
in  tlic  infi'ri<ir  venu  cava  is  directly  transmitted  to  the  bepaiic  vein  and 
to  tl»o  cvntral  vein  of  tbc  lobule.  The  capillitrieM  are  necessarily  dis- 
teitded,  and  conseijuently  the  bi^'patic  cells  are  compressed  and  0att«nod. 
At  tbe  same  timo,  from  the  inlltience  of  the  .Mirrounding  blood  pressure. 
tliey  arc  infiltrated  with  tlitid  coiitnining  coloring  sulMiance,  and  have 
in  their  prolopla^m  red-brown  grannW  of  bieniatin.  The  pre^^urv  con- 
tinuing, they  become  more  granular,  griidiially  thin  and  atrophied,  itnd 
may  even  comiileteiy  disain*ar,  so  that,  in  ]<oiuts  of  the  hepatic  hibule, 
tltc  distended  vessels  &r«  not  soparatod  by  colls.  Those  arc  the  esaen- 
tial  lesions  observed  in  cardio-pulmoiiury  aâecûous,  and  ptutîcularLy  in 
lesions  of  the  mitral  valve. 

In  tmuut  hepatic  eoi]i;estion8  not  accompanied  by  any  impediment  to 
the  blood  circuliitiun  of  the  liver,  the  ct-lls  arc  hyftertrophied  at  the  be- 
ginning. Thin  oecur»  es|>ccially  in  (he  licpatic  congestion  ohsened  at 
the  commencement  of  dittbelctt.  The  liver  ia  now  mitfomily  congested, 
and  the  cells  arc  lartJicr  than  in  the  normal  state;  they  also  contain  nu- 
merous granules  of  glycogenic  material.  The  entire  organ  is  hy]>crtro- 
phîed.  Later,  the  cells  are  loaded  with  fat  granules  of  medium  sise,  and 
the  liver  remains  hy|>erlrophied  or  retunis  to  its  normal  sixe. 

In  all  cases  of  increased  hlood  ]>rcsâuro,  the  cells  experience  analogous 
lesions:  increase  of  nutritive  activity,  when  the  blood  circnlatioii  is 
simply  accelerated  ;  atrophy,  on  tbe  contrary,  when  the  cells  are  com. 
prested,  when  there  is  an  obstruction  of  the  How  of  blood  through  the 
h«patio  vein,  while  the  pressure  is  the  same  in  llic  portai  vein  ;  pig- 
mentation of  the  cells  occurs  in  both  cases.  The  nuclei  of  the  hepatic 
«ells  are  usually  unchunged,  at  len«t  there  ia  no  atrophy  even  when  the 
compre^inn  exist»  in  a  high  degree. 

.\nother  «eries  of  modification*  of  the  cells  occurs  in  all  acute  and 
febrile  infectious  diseases  of  great  intensity,  as  typhoid  fever,  puerperal 
fever,  rariola,  particularly  hemorrhagic  variola,  scarlatina,  measles,  ery- 
sipelas, etc.,  as  well  as  in  acute  tuberculosis,  in  certain  poisonings,  aiid

it  \it  not  known  to  what  actua!  change  in  the  l>loo<l  \i  correspooda,  yet  it 
is  evident  that  it  k  rclateil  to  tin*  inlV-clioiiH  nature  of  the  ditteasc,  and 
lo  the  elevated  temperature  of  the  blood,  and  that  ii  ahoulii  be  oonaiii- 
ered  as  adding  to  the  gravity  of  the  diiieatie.  At  a  more  advanced 
period  of  the  disease,  there  are  found  in  the  cells  nnuieroua  fatty  graoalcs, 
and  a  true  fatty  degcticrution  of  the  li^er.  as  observed  at  the  tenmns- 
tioti  of  typhoid  f<-vvr.  In  other  diseases  of  tliia  grou)>.  csgwcially  in 
hemorrhagic  jaundice,  t)ie  cells  are  atrophied,  and  broken  down,  they  are 
infiltrated  with  yellow  granules  of  biUarjr  inattcr  in  connoclion  with  »llm- 
minoiiM  and  fatty  granules.  Inhales,  or  portion>(  of  lobuli^s  are  re])laeed 
by  the  débris  of  cells.  Post- mortem  decomposition  very  probably  jJays 
an  important  part  in  the  aofteiiing  of  the  entire  organ,  which  is  «o  very 
extensive  in  this  le^on. 

Acute  yellow  atrophy  of  the  liver  is  not  tbe  only  form  of  pnroMhyT 
matous  hepatitis  in  which  the  uu11m  are  infiltrate*!  with  biliary  pigment. 
In  the  liver  of  peraona  dying  frtim  hemorrhagic  variola,  there  ia  found  a 
simikr  k-siuu.  The  organ  in  now  large,  soft,  and  of  a  uniform  ffrayiab- 
yellow  color.  Nearly  one-half  of  the  hej<atic  cells  have  two  nuclei,  and 
are  cloud^'l  with  albuminous,  fatty,  and  pigmentary  granules. 

Tiiu  uiimerou»  general  febrile  diseases  all  cause  a  parenchymatoas

tlie  cell  is  preserved,  and  therefore  the  hepatic  cell 
is  not  destroyed.  It  ia  simply  surcharged  with  fat. 
The  protoplasm  of  the  cell  contains  either  several 
email  drops  of  oil  or  a  single  large  drnp,  which  occu- 
pies almost  the  entire  cell,  and  it  is  seen  as  a  circle 
of  pmtoplaem  surrounding  the  fat.  In  a  part  of  the 
protoplasm  the  nucleus  is  seen  well  preserved.  The

is  not  destroyed,  while,  on  the  contrary,  the  de;ieiie- 
rated  cells  filled  with  alhuniiuous  and  tatty  granules 
in  parenchymatous  hepatitis  are  broken  duwn  and  re- 
duced to  débris  followed  by  a  death  of  the  cell.  Each 
fatty  infiltrated  hepatic  cell  becomes  enlarged,  con- 
seT^ently  there  is  a  hypertrophy  of  th«  entire  liver.  A  phy  si  "logical 
intiltradon  of  fat  In  the  hepatic  cells  occurs  during  digestion,  and  at  the 
end  of  parturition. 

Avtylnid  dnjtnfrationt  which  is  found  in  analogous  pathological  con- 
ditions, aljo  affects  the  hepatic  cells,  transforming  tiiem  inio  small  blooka 
of  a  transparent,  refracting  mibsCance, 
easily  broken  into  small  cubeii.  The 
jEranulcs  aii<l  nucleus  of  the  cells  have 
disappeared.  These  small  masses  of

by  tincture  of  iodine,  and  frequently

with  sulphuric  acid,  they  are  colored

Sent  m.— Special  Pathological  Anatomy  of  the  Liver. 


PMT-mortrm  Chasob». — At  autoiwies,  the  liver  \*  generally  pnlc, 
jukI  more  or  lea*  bloodless — the  Urge  vessel:;  only  containing  blood, 

Sartieularly  tbi?  branches  of  the  hepatic  vein.  'Hie  siniill  vcji^els  and 
ranches  of  the  iiortal  vein  conktiu  very  little  blood.  If  a  large  fjuantity 
of  blood  is  founJ  in  the  vesiels,  tJie  liver  has  been  congested  during  life. 
The  absence  of  blood  in  the  small  vessels  of  the  liver  U  explained  by 
the  circutnslaDce  that  the  bile  destroy»  tin'  red  corpusclca  of  the  blood. 
This  disappearance  of  the  red  globules  explains  the  itpparcnt  nnarmia 
anil  [lulenesB  that  is  to  freijuently  met  with  at  post-mortem  vxaniinatlons. 
The  liver  may  also  be  fmind  tn/tmeif;  «ometinies  after  the  death  of  an 
animal,  the  protoplii-im  of  the  hepatic  veils  becomes  «olid,  so  that  one  or 
two  hours  after  deiith,  the  liver  lit  rigid  ;  but  thi^  cocidition  iIÎMippcars 
afteKa  few  houra,  and  nhen  an  autop>iy  is  made  twenty-four  iioim  after 
death,  the  liver  is  soft. 

The  diffusion  of  bile  occasions  another  phenomenon,  which  consista

Rllinj;  of  the  |H*rtid  vein  ;  in  the  otlicr  an  increased  blood  pre«sui«  in  tbo 
hepatic  vein. 

l*t.  After  eating,  the  jiorlal  vein  contains  more  hlood  than  at  any 
other  time  during  the  day.  After  a  lar;;o  dinner,  during  which  co«»id- 
eralile  wine  ha^  been  imbibed,  tlie  blood  of  the  intcalinal  and  rtplenic 
veins,  loaded  with  the  absorbed  fluids,  is  emptied  into  the  liver,  which  ia 
congested  and  enlarged.  Tlicre  is  now  felt  a  sensation  of  fulness  in  llie 
right  hy]>ocbondriuin,  or  at  times  sn  uneasiness,  or  actual  pain.  From 
Una  filling  of  its  vessels  the  liver  may  increase  one-thini  its  normal  use, 
I  vbich  may  be  deroi^nstrated  by  |H'rcii**îiin.  There  is  here  an  exaggera- 
tion of  a  physiologieul  function,  the  ehiborittiou  of  the  intestinal  blood 
by  the  hepatic  eland.  These  errors  in  diet,  when  repeated,  or  when 
tney  become  linbitiial,  may,  by  the  eonllcninl  congejition,  lead  to  cirrhosis 
or  g^uit.  Wrilent  u]ion  fçout  h;ivc  pointed  out  thut  in  iminy  cases  the 
disease  is  prt-i-eded  by  a  hepatic  congestion,  ('ttnge.ition  of  the  liver 
from  a  too  niln^i;;enûus  and  too  alcoholic  diet  is  an  important  faetor  in 
the  {general  alteration  of  the  blood  which  Murchison  t«nia  uriewnna

Great  heat  is  a  cause  of  hepatic  congestion,  and  sometimes  of  exag- 
^rated  secretion  of  bile.  In  warm  countries,  this  is  a  common  ooudition  : 
but  heat  alone  is  not  the  most  energetic  agent;  alcohol  has  aUo  an 
im/wrtant  intluencc,  and  so  also  has  malaria.

the  blood  flows  from  the  small  vcsaela  and  distended  large  trunks.  The 
histological  appearances  are  nearly  tlic  same  as  those  observed  by  Grie- 
singer  in  Kgypt  in  bilious  typhoid  fever:  congestion  at  the  beginning, 
followed  by  biliary  and  granulo-fatly  infiltration  of  the  hepatic  colls. 
In  tlic  latter  stage  ilic  liver  is  normal  or  diminished  in  sise,  ito  color  is 
y  el  1 0  wish-gray  and  opaque  as  in  yctlix»  fever. 

Something  of  a  similar  nature  is  met  with  in  our  climate,  altliougit  of 
less  intensity,  during  extreme  heut  and  fmm  other  cnuitcs,  suoh  as  improper 
diet,  alcoholism,  etc.  There  may  occur  wltli  jaundice,  bîlioai  gastric 
derangement,  vomiting,  bilious  stools,  coincident  wiih  an  increase  in  the 
siic  of  the  liver  and  a  febrile  state  of  short  duration.  This  is  an  in- 
creased  secretion  of  bile  with  hepatic  congestion,  and  should  be  distin- 
guished from  another  variety  of  simple  jaundice,  also  frequently  accom- 
panied with  congestion,  which  is  due  to  an  intestinal  catarrh,  with  catarrh 
of  the  biliary  passages,  and  obstruction  of  the  latter  by  plug»  of  mucus. 

Most  of  tlie  low  infectious  fevers  of  our  climate,  variola,  tjphoid

tlic  dilTerenoe  in  the  color  of  their  centre  and  periphery  is  more  dïBîcuU 
to  appreciate  by  the  unaided  eye  ;  again,  th&tv  is  now  always  a  new 
formation  of  connective  ùsit^ie  around  the  central  veins  of  tbe  lobules 
and  the  aub-hepalic  vein  ;  this  timsuc  is  also  noiformly  colored  red.  Sec- 
tion* of  these  livers,  examined  mtcrojopically,  presoui  a  zone  of  newly- 
formed  connective  ^«sue  around  the  central  dilated  rein.  In  thi*  zone 
of  Bbrillar  ti^ue  tliere  exist  cells  with  an  oval  nucleus.  The  hepatic 
cclU  arc  atrophied,  finely  granular,  and  often  r«-duced  to  a  mass  of 
albuminous  and  fatty  granules.  Tne  capillaries  are  ni)t  always  so  much 
dilated  a»  in  the  preceding  stage.  Tnis  state  const itntt-s  a  sclerosia 
around  the  hepatic  vein,  or,  bettor,  a  peri-phlebitis,  a  thickening  of  the 
external  coat  uf  the  vessel. 

In  such  cases  a  true  cirrhosis  is  said  to  exist,  coraparahlc  to  cirrhoeis 
of  alcoholie  origin  ;  the  lesion  is  not  freijuont.  Recently,  however,  at 
tlic  autoiisy  of  a  woiiian  nh"  dittl  with  stenosis  and  double  insufficiency 
of  tJie  mitral  and  tricuspid  orifices,  we  found  the  peri-lobular  vewels  also 
surrounded  hv  a  aone  ot'  silenisis.  There  was  around  some  (im!  all)  of 
the  interlobular  branches  of  the  portal  vein,  fibroid  connective  tissue  con. 
tnining  cells  of  this  tissue  and  forming,  upon  section,  small  circles  inclosing 
both  the  hcjKitic  arterioles  and  small  branches  of  the  biliary  canals  w  hicb 
aceomjmny  the  portal  vein  ;  but  the  new  connective  tissue  did  not  form 
|ierfcct  ciixic*  around  each  hepatic  lobule,  as  seen  in  well-marked  cir- 
rhooin.  This  red  atrophy  «f  the  livcr'hiif  U-en  differently  interprctt'd  hy

aiilo[>Hy  none  of  the  chamcterUlic  Ittflioii»  of  a^uie  atrophy.  In  oiir  ovrn 
otise nations,  however,  we  have  atwayx  found  the  characteristic  levions, 
when  a  fatal  idiopathic  icteniH  had  been  the  cause  of  death. 

In  patioim.  observed  during  tbe  short  duration  of  their  disease,  it  may 
fcc  demonstrated  that  the  liver,  of  normal  or  increased  size  at  the  liej-in- 
nîng  of  the  nialadr.  diminishes  in  volume  during  the  course  of  the  afteo- 
tion.  At  tlie  autopsy,  the  Hver  is  more  or  less  atrophied,  aceordinp  lo 
the  dnnition  of  the  disease  ;  it  is  Mofier  than  nonnul  :  the  greater  the 
atrophy  the  mnre  the  softeninp.  The  ca]K<nle  of  Glisson  may  he  pinched 
u)>  between  the  finger*.  When  the  liver  i»  lakcn  in  tbe  hands,  its  soft- 
netw  and  llnbhine:4K  can  be  bc»t  appreciated.  It  feelii  like  a  Hemi-fluid 
inasA.  The  color  of  its  surface  i'<  like  yellow  oebre;  upon  section  tbe 
.  oolor  and  softness  are  found,  and  it  present"  a  homogeiicoits  sur- 
virin^  to  the  liepatic  Inhulcs  heiii;;  uniformly  colored. 

The  gall-bladder  and  Hilary  canals  contain  very  little  bile,  or  bile 
which  is  slightly  colored,  or  at  time*  evon  colorless.  Microscojiic  ex- 
sminntion  of  the  fluid  obtained  by  scraping,  shows  a  small  numlier  of 
hepatic  cells  of  normal  size  and  shape,  outuining  fine  albuminous,  fatty 
mid  numerous  yellow  biliary  pigment  granules.  Most  of  the  cells  are 
very  much  smaller  than  nonniil  ;  their  edges  are  thin;  they  are  broken 
into  fragini-ntîi,  and  the  grannhir  |irotopla)tni  of  tlic  fragmeifts  contains 
felty  an<l  biliary  granules.  In  places  where  tlie  aofleninj;  i.t  very  great, 
none  of  the  hepatic  cells  have  retained  their  physiological  shape  «r  sine. 
The  fluid  scraped  from  these  places  contains  only  small  masses  of  granu- 
to-fatty  and  pigmented  substance,  in  the  centre  of  which  there  is  not 
always  a  nucleus.  The  latUT  luvs  been  set  free  through  the  softening  of 
the  protoplasm  of  tlie  cell  as  welt  as  by  the  niechnnicnl  force  employed 
in  tlic  method  of  preiwiration. 

Acconling  to  moMt  piithobigio.al  anatoniists,  the  peripbcml  connective 
tiiwue  of  the  lobules  iind  thul' accompanying  tlie  capillaries  of  the  lobules 
nndergoes  au  al bumi no- fibrinous  infiltration,  in  which  are  found  escaped 
lymph  celU.  niis  întlainination  of  the  perijiliera!  connective  tiiwue  of  the 
lobiile  is  the  initial  k'liion  of  atrophy,  aceordinii  to  Winiwarter,  who  ho» 
seen  a  patient  who  died  twonivfour  hours  alter  the  beginning  of  the  ilim 
easc.  He  also  thinks,  with  Ilolm  and  lliittenbronncr,  that  the  segraent- 
stion  of  the  hepittic  cells  loadi  lo  their  triinsformation  into  connective- 
tissue  cells.  This  we  btdicvo  to  be  an  error.  Wc  have  never  seen 
tliickeiiiug  ot  iioiublc  iiiflamiaation  of  the  pcri-lobvdur  connective  tissue  in 
this  disease. 

At,  the  autopsy  of  one  case,  we  observed  around  the  hepatic  lobules  the 
network  of  biliary  canalx  penetrating  into  the  external  third  or  half  of 
the  lobule.  In  this  ca.*e  tlie  acute  yellow  atrophy  was  chronic  and  had 
reached  to  a  very  advanced  stage  in  the  destruction  of  the  hepatic  cells- 
Thin  sections  showed  the  canals  in  the  midst  of  a  fibroid  tissue.  The 
i  hepatic  cells  had  entirely  disappenred,  and  there  remained  only  tbe  capil- 
lane4  and  fibrous  framework  of  the  lohule.  Tbe  larger  inierlobular  bi|.

In  rejçard  to  tbe  initial  legion  of  tlie  liver,  we  are  without  a  aatiflfactory

Orave  idiopathic  icterus  may  be  connected  with  acute  yellow  atrophy

Iioi*niiiii;f«  aiifl  in  grave  typhoid  fever.  Tiy  a  number  of  its  symptom* 
and  lumtiiniiciii  lii»i<m«,  phosphorus  poisoning  is  closely  relateil  to  grave 
icterus,  lint  in  this  poisoning,  falty  def»iieniti<in  of  tbe  cells  predonii-

cell»  ia  comparable  to  that  produced  by  pboHpboruH,  but  in  leas  tntenite. 

»Tbc  infectious  diaeaAe»,  the  iclertiii,  wiihbœmaturia,  of  warm countrie.i, 
the  febrile  disease»,  sueb  an  pneumonia,  tiiherculosis.  present  different 
de;;reoaof  parenchymatous  bepaiitis,  which  vary  according  totbe  diMwe 
ftikd  itd  intensity.  The  lesions  of  j)areii(!hym»tou*  hepatitis  are  comparable 
B^to  those  of  acute  yellow  atntphy,  hut  they  are  less  intense  and  less  per* 
Hmttly  marked.  Thus  in  icterus  with  Jiieniaturia,  the  liver,  after  having 
B  ]>een  congested  and  ecchyinosed,  parses  to  a  state  of  fatty  degeneration  of 
B  iU(  celU,  cbftraeterixed  to  the  unaided  eye  by  a  yellowish  tint.  Tbe  same

In  tbe  liver  of  typhoid  fever,  there  is  frenuenlly  olaerved  at  the

cides with  the  cloudy  swelling  and  lesions  of  the  cell.*  previously  de-

ftt  the  end  of  the  disease,  instead  of  the  surface  heiug  uniform,  the 
lobules  are  red  at  their  central  part  and  grny  at  the  periphery,  in  coiise-

5th.  miiary  Ahtftitf». — Almost  the  only  eausc  of  inflammation  of 
the  iniicoiis  membrane  of  the  biliary  iMssascB  is  the  presence  of  t-iliarv 
cnlciiti  in  their  interior.  Tlie  Mnull  calculi  resembling  sand  or  fine  t^rat^cl, 
calculi  which  are  irregular,  nnj^nlar.  formed  of  ptf^ent,  cholesteriu, 
and  ealcan-ouK  sall^,  and  which  exist  in  the  hepatic  canaU  and  tlieir  in.

tlieme  eaiials. 

(j'alarriial  inflammation  of  the  biliary  paa-^ages  in  the  liver  varies  m 
intensity  :  sometimes  it  is  limited  to  the  secretion  of  a  slightly  turbid 
mucus,  colored  by  the  biliary  mntcrial.  and  is  accom|^inie<l  by  a  certain 
amount  of  dilatation  of  the  canals  which  fre(|uently  iiave  aiapullar  ca- 
larfK^ments  alonj;  their  course.  The  fluid  contains  lymph  cells,  cylindrical 
cells,  biliary  pigment,  and  fine  ^niuules.  It  ii  in  inflammations  of  llii* 
kind  that  biliary  absceiwes  of  Ibe  Hver  most  freipieiitly  occur. 

Ill  other  cases,  the  intliimmatiou  of  the  biliary  ;«.'<<«£ <;e<i  in  very  intense, 
and  tho  dilated  canals  are  completely  and  uniformly  fillinl  with  a  thteic,

By  its  development  and  progreas,  an  abscess  at  the  f^riplierv  of  tli«  liver 
has  a  temioncy  to  open  spontJineously  ;  most  frerjuently  it  [wintii  upon  the 
superior  surface  of  the  Hvcr  at  the  diaphragm,  or  at  the  liorder  of  tli« 
tnic  or  false  ribs,  or  a  little  below  upon  the  aMomimil  wall.  When  the 
abscess  is  covered  only  by  the  c:a|isule  of  Ulixson,  and  Is  thus  connected 
witli  the  peritoneum,  there  occurs  a  local  peritonitis,  and  the  irrescnce  o(

Qentral  Otrrkoti». — The  cirrhoses  which  involve  the  entire  liver  are 
generally  due  to  alcoholism  or  to  syphilis.  Sometimes  they  folluvr  intor- 
iDÎttent  fevers,  or  a  residence  in  wann  cUmatvs,  in  patienta  in  whon 
alcoholism  has  had  considerable  iniluencc  in  cuiuioction  with  fever  or 
with  dyseiitc^ry.

But  these  lar^e  granulations,  which  to  the  unaided  eye  npf}ear  hoiuo-

the  lobules  is  very  resisting;  it  is  impossible  to  tear  the  hepatic  )iart>n-

tli«  hejnlic  celU  are  atrophied  and  replaced  by  fihroiu  tissue,  th«  biliary 
canals  remain,  and  become  very  distinct.  It  is  possible  then  that  the 
biliary  caiiab  seen  in  cirrhosis  aro  only  normal  inter-  and  intra-lobn. 
Inr  canals  mailo  more  distinct  in  consoiiuonco  of  th«  atrophy  of  the 
imrencbyma.  Only  the  interlobular  biliary  Vl^88l'ls  in  man  arc  well  nn-

.lH)l:i  mm.  to  .W-IH  mm.  in  diameter  (see  «nf*->.  This  system  has  not 
been  satisfactorily  studied  in  man.  The  biliary  canals  so  numerous  in 
cirrhotic  tissue  in  which  they  form  a  network,  are  very  similar  in 
diamclcr  and  constitution  to  the  inti.-rlohular  canals,  and  do  not  corre- 
spond to  the  description  of  întmlubulur  canals  of  animals.  The  meshes 
which  they  fonn  in  the  new  ((ulero»ed  connective  tissue,  are  also  Inrzer

''niDg  of  the  cirrhosis,  the  prc-exi^tiii^  canals,  situated  lu  an  intlarnnuilory 
tissue,  increase  in  length  and  luimber  by  an  extension  of  the  epithelium, 
which  nominally  exists  in  the  peri-lobular  canals  with  which  they  com- 
municate. 

When  the  thickened  connective  tissue  which  separates  several  lobules 
in  cirrhosis  with  hypertrophy  is  examined,  there  is  fre(|ucntly  seen,  in  the 
centre  of  the  area  occupied  by  the  connective  tissue,  one  or  more  large 
biliary  vesst-ls  surrounjed  by  ïoiics  of  embryonic  tissue  consisting  of

We  will  «tudy  here  some  of  the  pecidiurities  «f  carcinoma  nhich  Wloii;t

One  very  remarkable  character  of  cancer  of  the  liver  is  Uiot  llie  tntnw 
may  invade  an<l  fdl  the  ditferent  branches,  the  trunk  aiid  nei^btxma:; 
divisions  of  the  port;il  vein.  Wo  have  several  limea  seen  aMociatnd  »ilh 
a  telangiectatic  cancer  of  the  stomach,  a  carcinomatous  formation  of  the 
same  nature  in  the  portal  vein. 

In  this  variety  of  carcinoma  the  net  work  of  telangieclattc  capillariei, 
and  the  isolated  spherical  ancurisraal  dilntutions  are  very  easily  reeo;;- 
iiized  by  the  naked  eye  as  rinuoiis  lines  and  isolated  red  jmints.  In 
those  case^  which  we  have  seen,  the  ulcerated  tumor  of  the  stomacli

tortuous  conia  of  tlie  siee  of  n  crow  or  gooM  (|uill,  which  were  nothing 
else  than  the  afferent  branches  of  the  (lorfnl  vein,  which  could  be  easily 
followed  up  to  the  trunk  of  Uie  vein.    When  opened,  ihew  veins  appeared

In  other  ca»e«  a  carcinoma  of  the  lymph  ^^lunijit,  whether  primary  or 
•«couilary,  or  of  other  ti^iAue»  in  the  vicinity  of  the  jiortal  vein,  tnvailcs 
the  wall  of  the  vein  am)  thus  reachvti  the  Inmcn  of  the  ve»->el  into  which

under  the  influence  of  tlie  blood,  and  beooaie  ilt^tnched  and  form  ;;eiiuinc

beeooie  tlie  point  of  departure  of  secondary  tumors. 

The  neoplasm  occuj>yinj{  the  portal  vein  mavi  at  a  ^ven  moment, 
ulcerate,  and  there  may  thus  result  a  complete  to»  of  substance  in  the 
wall  of  the  vein. 

In  several  observations  of  melanotic  carcinoma  of  the  liver,  reported

with  the  cclltdar  clenicnU  of  the  tumor  (radiated  cHrciiioriia  of  Itind-

l.ast]y,  «e  have  met  with  an  example  of  iieunndary  melanotic  carcinoma 
of  the  liver  in  which  the  new  formation  at  first  sij^hi  appeared  to  be 
irrcijularly  infiltraled  throufîhout  the  entire  orjjati,  l'[)OU  lliin  «eelions, 
examined  under  the  microscope,  it  was  seen  that  most  of  the  vessels 
belonspng  to  the  portal  vein  had  a  much  larger  diameter  than  normal, 
and  were  of  cylindrical  form.  Their  wall  was  the  seat  of  a  largecelle-l 
infiltration  ;  their  inner  membrane  presented  coonoctivo  tissue  eravktions 
infiltrated  by  the  same  lar;;e  cells.  These  regular  elevations  filled  tho 
whole  cidibrc  of  the  vcsacl,  or  left  a  central  lumen  occupied  by  free  cells 
and  Wood.  The  cellular  elements  wurc  more  or  less  pignu^ntcd.  .\lnio«t 
all  the  ve»sel>i  were  ult^^red  in  ihi*  manner.  The  hepatic  arterie»  were 
not  the  !tcat  of  rto  intense  a  cnreinom.ttouis  endarteritis,  hut  they  alxo

cells  with  larjpj  nuclei,  largo  nucleoli, and  a  protoplasm  for  the  most  part 
pigmented.  The  thickened  connective  tissue  which  accompanied  the 
vcsmIs  formed  the  stroma  of  the  carcinomatous  alveoli.  The  intor- 
lobnlar  biliary  cnimis  were  also  to  be  rccogniiccd,  hut  their  swollen

The  egjçs  of  these  worms,  discharjied  with  the  fecal  mattar  of  the  animal

When  the  hydatid  cyste  reach  their  full  development,  and  ttill  romatn

such  cysti  of  the  sÎEc  of  a  list,  or  greater.  Tlii'ir  fibrous  membrane  is

JMted  and  contains  a  [lalo,  stringy,  imn'oiw  hile  with  piw  coq>ti*cles. 
This  ia  eflpecially  seen  in  connection  with  inflfvinmnlion  of  the  hilîarjr 
canals.  The  mucous  membrane  k  thickened,  roiij^licnod.  and  «cdematoufl, 
instead  of  bavin;;  its  ordinary  ihinnexs  and  delicate  villous  surface.  In 
a  mora  intense  de);n«  of  the  Ic^oti,  there  are  found  one  or  more  ulcers 
npoii  ihc  mncoufl  membrane,  especially  at  the  inferior  portion  of  the  gall- 
bladder. These  ulccmlion*,  when  they  are  ra|>iilly  produce<l  by  a  puru- 
lent infiltration  of  the  connective  tiisue  of  ibe  mucoua  membrane  which 
extends  u>  the  mtticnlar  layers,  may  occasion  fatal  perforations  of  tJie 
|)«riu>neum  and  an  escape  of  the  cafculi  into  its  cavity;  but  this,  how- 
ever, is  a  very  uncommon  accident.  The  ulcers,  «hen  thev  exist,  arc 
accompanied  only  with  a  local  irritation  of  the  peritoneum,  which  is  seen 
upon  the  externa!  surface  of  the  ;;nU-htAi]der  opposite  the  point  of  dis- 
ease, where  are  Tound  fihrinonit  f»l«e  membranes,  or  a  fibrous  thickening 
of  tlie  serous  mcraliranc  irith  ndhoionx.  Iiocal  péritonites  with  adhe- 
sions have  resulted  in  communication:*  "f  the  ;»ftll-bUddcr  with  the  duo- 
denum, with  the  colon,  and  even  in  biliary  fiittulic,  opening  externally 
through  the  ahilominai  wall,  calculi  having  been  discharged  by  these 
several  pcuiitagea.  '  In  all  thcBe  cases  the  intlammatinn  extends  to  the 
cystic,  hepatic,  and  common  biliary  ducts,  causing  an  icterus.  While  the 
presence  of  calcuii  seldom  occanion.  these  fata!  results,  they  frci|Hently 
cause  a  thickening  of  the  mucoun  membrane  of  the  connective  tissue  and 
muscular  fibres,  comparable  to  tJic  hypertrophy  of  the  urinary  bladder 
caused  by  cnlculi  in  that  or^an. 

Lotus,  Amiral,  Kokilaiwky,  etc.,  have  described  an  infillmtion  and 
gangnoous  ulceration  of  tJie  nincnus  menibmneof  the  gall-blnddtsr  ocuur-

Catiirrhal  inllammation  of  the  common  biliary,  cyxlic,  and  be^iutic 
ductal  frei(uentlr  occurs  either  srionlaueouitly  or  in  conseiiuciice  of  an 
inflammation  of  the  duodenum,  when  it  causes  catarrhal  or  simple  icterus, 
.\l  other  tiroea,  it  i.i  due  to  biliary  calculi  coming  from  the  gait-bladder 
or  formed  in  the  hepatic  canals.  Jtiliury  gravel  or  small  fragmenta  of 
calculi  are  the  most  active  causes  of  this  inflammation.  Kvery  stage 
has  been  observed  between  the  swelling  of  the  common  biliary  duct 
limited  to  the  ampulla  of  Vater.  or  to  the  neighboring  portions  of  the 
duodenum,  where  it  arrests  the  flow  of  bile,  in  simple  icterus,  and  acute

more  rarely  it  beloiifç»  to  scirrhus.  Its  Anatomical  form  is  very  similar 
to  that  occtirring  in  the  intestine.  Generally,  indifd  fourteen  lime»  in

ber (he  larger  the  calculi.  The  bile  is  ftometimes  coIoHch^,  or  it  it*  thick 
and  brown;  it  may  contain  small  fragmenlji  detached  from  the  tumor.

nlatin^,  for  new  formations  assume  the  villous  iorui  in  the  gall-Madder, 
just  as  in  the  urinary  bladder.  The  tumor  invades  a  part  or  the  entire 
mucous  surface,  which  is  increaaed  in  thieknesa.  and  upon  section  ahows 
colloid  tissue,  or  a  «hitish  tissue  infiltrated  with  a  milky  juice.  The

the  bands  of  udln-Kion  forni>-d  between  tlie  viitceml  and  parietal  peri-

In  other  caneii  acute  purulent  periionîti»  terminates,  after  the  absorp- 
tion of  a  |)ortton  of  the  exmlated  tluid,  by  a  kind  of  oaseation  or  iiispis-

in  iesiouii  of  the  liver,  gall-ljltiildcr,  spleen,  in  diaphrn;^uiatic  pleuritia, 
in  melritt.s,  iu  intlammaiioiis  or  tumors  of  the  appendages  of  the  utertu, 
in  cystitis,  iu  typhlitis,  etc. 

General  ehrotiin  perltoniti»  follows  acute  peritonitis,  or  it  is  chronic 
from  the  beginnin;;.  In  the  latter  case,  it  is  seldom  that  it  cannot  be 
referred  to  a  chronic  peritoncul  or  intoWinal  lesion:  tubercuWis,  carci- 
noma of  one  of  the  abdominal  organs,  cirrhosis  of  the  liver,  disease  of 
the  bean,  malarial  cachexia,  etc. 

As  carcinomatous  peritonitis  i.*  superficial  at  it»  be^innin;*,  as  well  as 
in  it»  »ubsei|ucut  developniL-nt,  there  are  found  upon  the  surface  of  the

Therefore,  sometime.4  a  cai-ctnonia  of  the  peritoneum  may  be  suspected 
after  a  nûcroscopical  examination  of  the  fluidohtaiuel  by  an  explnra- 
torv  puncture. 

The  lesions  of  chronic  iicritonitis  vary  much.  Thus,  in  chronic  peri- 
tonitis following  acute  pentooiUs,  there  are  found  adhesions  between  the 
intestinal  loops,  or  between  the  loops  and  neigh  borin;;  organs  or  abdom- 
inal wall,  consisting  of  filamentous  or  lamellar  fibrous  tissue.  Com- 
plete obliteraiion  of  the  peritoneal  cavity  may  occur,  just  as  obliteraiiou 
of  the  pleural  cavity  often  happens  in  pleuritis.  That  life  may  be  pro- 
longed even  when  tlie  intettinvt  are  coutractod  by  the  interference  and

ducts,  tlie  ibin  wall  of  which  consUtH  of  connective  msne  and  elaatuB 
fibres,  are  lined  hy  a  single  layer  of  small  cylindrical  epithelia)  cells. 

When  these  ducts  are  injectvd  with  a  eohition  of  l'niïsian  blue,  with 
«ontiniiokis  and  slight  jirewure,  the  injection  at  first  jiciielrate!"  Into  the

complete  network  around  the  ^landidar  colls.  TiiU  nelvrorkof  caiialicidi 
is  coiiiparnbie  to  that  of  the  intralobular  hUiary  canaliculi. 

The  acini  of  the  ^land  are  imbedded  in  a  nia^  of  adipose  tissue,  which 
contains  the  bloodvessels  and  nerves.  The  bloodveiaels  and  lympliatks 
liave  the  same  arrangement  as  in  the  satiiary  glanda.  The  nerves  oome 
from  ibo  great  eympathctic,  consist  moatly  of  fiiw  Gbre«,  and  accompany 
tht  vessels. 

The  pancreatic  juice  ts  ctesr,  lîmptd,  slightly  viscid,  alkaline,  conlaim

lacenus  suhslances;  llnally  it  ajuists  in  the  digestion  of  nitrogenous  sub* 
Stances.  Therefore  the  pancreas  is  one  of  the  most  tsteniial  glands  in 
intpstânai  digestion,  if  it  is  not  positively  necessary  to  life.  When  the 
pancreatic  juice  does  not  reach  the  intestines,  the  fatty  substances  are 
incompletely  digested,  and  they  are  found  in  the  feces,  which  are  geue- 
rally  lifjuid  (tatty  diarrhœa).

According  to  Hoffmann  the  pancreas  is  always  altered  in  typlioid  fever

Jnter*tili<il  Infiitnnniiliiin  may  occur  in  tlie  connective  tiasne  of  the 
pancreas.  'Hie  few  caiscs  of  ihia  lesion  which  have  been  nporteil  show 
that  the  heail  of  (he  pant^roas  joins  in  the  chronic  inflamntatory  Uiicketiing 
of  the  connective  tissue  which  surrounds  it  and  the  duodenum.  Thi*  is 
ol^en  seen  when  a  biliary  calculus  is  arrested  in  the  duetiut  communis 
choledochus  near  the  diKidcnuni  and  muses  a  chronic  inflammation  of  all 
the  surroutKlini*  coniK-ctive  tissue.  In  caiM!*  of  twmon»  of  this  rc^rion.  or 
in  simple  ulcers  of  ihe  pylorus  or  duoileninn,  etc.,  the  pwcreatic  duct  is 
cither  uonnal  or  contracted. 

Induration  «/  the  l'nntreat. — We  have  fretjuently  examined  psn. 
creanes,  bard  and  of  a  f[j*y  color,  in  which  the  ;;laiidular  acini  vere 
perfectly  marked  out.  This  condition  has  been  taken  for  scin-bus.  In 
our  examinations  we  found  no  very  appreciable  lesion  of  the  or;nin. 
Its  appearance  would  suggest  to  a  beginner  only  the  idea  of  cnttccr. 
Accorain;;  to  Kkbs,  it  is  possible  that  there  may  be  a  ptirenohyiniitoiis 
inflammation  similar  to  that  of  typhoid  fever,  or  a  new  fonniition  of 
acini  (an  adenoma),  or,  as  Vulpian  bctteves,  «  thiikeiitng  of  the  connec- 
tive tissue  of  the  organ.  In  cases  of  induction  «een  by  us,  tiic  acini 
were  large  and  well  develoiicd,  and  appi'ureti  normnl.  as  ilid  alHO  their 
cells  ami  connective  tissue,  yet  the  latwr  presented  no  adijioHe  ttsHue; 
on  the  other  hand,  when  the  pancrea»  i*  mti.  and  the  acini  are  ?<niall 
and  atrophied,  a  hoU  and  very  abundant  adiposie  tissue  takea  tlie  place 
«f  the  glandular  parenchyma. 

Faltv  Defeneration  and  InSltration. — Fatty  infiltration  of  the  epithe- 
lial cells  of  the  glandular  acini,  and  a  new  formation  of  adipojte  tinsue, 
should  not  be  confounded  with  one  another;  they  are  distinct  changes 
which  bave  nothing  in  common. 

Granular  faftit  ({((feneration  of  the  efuthelial  cells  of  the  acini  is 
seldom  seen,  and  the  conditions  under  which  it  is  found  are  not  well  de*

Atrophy  of  tlie  pancreas  may  occur  from  rarioua  eauaea:  1st,  from 
nresaure  from  without,  exercined  upon  the  glan<l  hy  ncighlMrin^  inmom  ; 
2<l,  fVofo  pressure  from  within,  bv  distension  of  cysts,  eauseit  l>y  eoncrv- 
lions  in  the  excretory  ducts  of  the  gland:  3d,  from  granular  fauy  de- 
Cencrattoii  of  the  epithelial  ccUh  of  the  acini  ;  4ih,  from  intonuitial 
inBaminatJon,  and,  aceonlin';  to  Kolb,  esiiecially  hr  ota^iB  of  blood  in  the 
gland  in  consv<iuence  of  chronic  di^caMis  of  the  heart,  liver,  und  lungs. 
>lunk  and  Sylver  have  each  «ee»  a  ease  of  atrophy  of  the  pnncrea»  in 
diabctc-s.  Sometime:*  the  atrophied  neini  are  replaueil  by  adipose  con- 
nective ti.'««ue,  which  forma  around  them;  .«omeiimai  there  i»  no  incruftM 
of  fat,  hut  the  acini  are  found  in  the  midst  of  &  loose  coniiMlivd  tiswue, 
and  the  nancroaa  is  mueh  atrophied  both  Id  appearance  and  realiiy. 
This  condition  is  frequently  associated  with  calcareous  concretions,  or 
with  a  whitish  pulp  contained  in  tlic  ducts. 

ylini/hid  Pf'jrnrmli'in. — Acc.onling  to  Rokitansky,  the  cells  of  the 
acini  may  undt-igo  amyloid  degeneration,  The«  cases  arc  very  rare, 
and  cvi!ii  iloubtfiil.  The  veaseU  of  the  paiicrcM  have  wvcral  times  l^'en 
found  in  a  ftate  of  amyloid  degeneration  in  connection  with  «imilur  con- 
ditioiu  of  the  liver  and  spleen. 

Tl'Moiui  OF  TUK  Pasceba». — Tubereulovi»  of  the  pancreaa  m  «el 
occurs  that  Cruvcilhier  was  inclined  to  doubt  ita  existence,  and  believ 
thai  the  casts  regarded  as  such  are  only  a  caseous  alteration  of  the  nei;^- 
boring  j^lands.  The  lulicrcukiHiB  of  the  pancreas  is  always  secondary  to 
that  of  the  lung»  and  peritoneum;  the  miliary  tuWrcle  granulations  are 
developed  in  the  connective  tissue  separating  the  adni.  to  a  case  re- 
ported by  Aran  there  •tofi  a  tuberculous  caseous  mass  in  the  acinus  itself.

primary  or  secondary.  From  ihe  AlatUtic»  of  Willt;tk,  of  -lli"  casi-s  of 
carcinoma.  \t  were  carciooma  of  the  paucrcas,  the  majority  being  eccoud- 
»ry.  Primary  carcinoma  is  most  frequently  devdopet]  at  tbo  bead  of 
the  pancreas,  very  seldom  at  the  left  extremity  or  middle.  As  nrimary 
carcinooia  of  the  pancréas  very  soon  extends  from  ibc  bond  of  this  or-;na 
to  the  neighboring  part^,  to  the  duodenum,  lymphatic  glands,  duct»,  etc.. 
it  U  very  difficult  to  determine  its  origin  ivheu  a  tumor  including  tht-so 
organs  iii  found  at  the  autopsy. 

I'riinnry  carcinoma  may  W  either  scîrrliou»,  cncepbitloid,  or  colloid. 
It  may  hegt»  by  one  or  more  tiimon»  which  uro  unitei),  when  a  portion 
of  the  gland  i»  hoo»  transformed  into  a  itiitform  cancerous  mast«.  When 
tlie  lumor  U  limiti-d  to  the  head  of  the  pancreas,  the  canal  of  Wirsung  is 
contracted;  it  leaiU  from  the  duodenum  into  an  indurated  tisiiue  vrbieh 
compresses  it,  and  the  disuharge  of  nancrealic  juice  is  prevented.  If  the 
loft  half  of  the  pancreas  is  not  included  in  the  lesion,  but  continues  to 
BccreU'  somvwhat  altered  juice,  the  excretory  ducts  are  dilated  in  this 
portion  of  the  gland,  and  form  cyst*.  The  subserous  connective  tissue, 
the  muscular  layers,  and  tbo  submucous  connective  tissue  of  the  duode- 
num, as  well  as  the  ampullfl  of  Vater.and  ductus  communis  choledocbiis, 
Mon  bMome  involved,  and  there  frei(nent1y  re^ultji  a  narrowing  of  the 
duodenum,  perhaps  conMderable.  followed  by  an  icteru»,  etc.  The  cxl«n- 
ÛOQ  to  the  lymphatic  glands  may  occasion  pressure  ujion  the  vena 
porta;  the  infiltration  of  the  subperitoneal  connective  tissue  terminates 
ny  compressing  and  narrowing  the  aorta.  The  stomach  is  very  seldom 
flccoadarily  invaded  by  the  tumor.  Klehs  and  T.iicke  have  reported  a 
primary  colloid  earcinoma  of  the  pancreas  innhich  a  secondary  dropsical 
and  cystic  dilution  of  the  oinentuni  was  found  projecting  prominently 
hetow  the  transverse  colon.  This  secondary  tumur  of  the  peritoucum 
bfl  been  punctured  during  life. 

Secondary  carcinoma  of  the  pancreas,  due  to  an  extension  of  the  car- 
cinoma from  surromidiii;;  jmrbt,  the  «toomch,  tlie  duoilonum,  the  liver,  the 
lymphatic  glands,  is  seldom  seen  in  the  form  of  isolated  nodules,  at  least 
when  it  is  not  a  melanotic  tumor;  generally  the  new  formation  of  the 
pancreas  ia  rlirectly  continuoiL^i  with  the  primary  cancerous  mass.  The 
nea^l  of  the  pancreas  ia  almost  always  the  Krst  region  invaded,  and  it  i^ 
unusual  for  the  entire  organ  to  be  degenerated. 

Cylindriesl-ceUed  eyitheiioma  of  the  pancreas  has  been  once  seen  by 
£.  Wngner.  It  probably  followed  a  similar  epithelioma  of  the  mucous 
membrane  of  the  duodenum.

The  splenic  artery  and  vein  enter  the  orsan  at  the  hilua,  surroiindod 

•  by  a  fibrous  shealh  provided  by  the  capsule.  This  §hoath  la  thinner 
than  the  arterial  wall,  but  thicker  than  the  venons  wall.  Each  of  tlie 
principal  branches  of  the  splenic  artery  divides  and  forms  bninchinj;  tufls,

Whvn  thufc  branches  have  a  diaroeter  of  .3  mm.  to  .4  mm.  they  are 
separated  from  the  reins,  and  have  along  tlieir  coorsu  the  Malpif^hian

Tho  Malpighian  bodies  or  eorpiisclcs  of  tho  spleen  are  sphnricnl  or 
oral  in  !iha]>e,  giiirroundin^  an  arleriolc  ;  their  diameter  varies  from  .2 
Dm.  to  .7  mm.  They  are  always  intimately  conitectoil  with  an  arlerinle,

eends  into  their  interior  small  arterioles  and  a  network  of  capillaries. 
These  corpuscles  consist  of  a  reticulated  tissiie.  similar  to  that  seen  in

«all,  and  are  limited  by  a  thickening  of  the  reticulated  tissue  ;  they  are 
lined  by  larjçe  fiat  endothelial  cells. 

Tbe  cellular  elements  contained  in  the  meshos  of  the  reticulum  of  the 
splenic  pulp  are  the  same  »s  tlios«  in  the  reticulum  of  the  Malpighii 
corpuscles.  From  tlio  above  description  the  corpuscle*  may  be  comgnr 
witn  the  follicles  of  the  Intestine  and  of  lymphatic  glands.  The  wliolll 
0ple«n  may  be  coniparei)  to  a  lymphatic  ginnd  in  which  \hf  medullary  sat 
atanoc  is  rcjilaced  by  a  cavernous  tissue  ;  the  veins  replacing  in  the  sp]c 
i.tbe  pori-foUicular  spaces  and  tho  lymphatic  caiwls  of  the  glands.  It  it 
'  evident  that  tlic  lymph  cells  are  able  to  paita  from  the  reticulate<l  tiuue 
into  the  hlood,  anil  from  the  bloo<l  into  tlie  reticulated  tissue. 

'i'be  mode  of  connection  of  tlio  arterioles  and  corpnacles  with  the  veo- 
OUH  network  of  the  pulp  is  not  yet  accurately  understood.  Ilistologista 
have  not  yet  agreed  upon  the  manner  of  communication  :  some  beliemg 
that  tlie  arteries  are  directly  continuous  with  tbe  veins  :  others  admit  tbe 
existence  of  an  int^nnfdiary  oapilUrT  network  ;  and.  finally,  othvi^  think 
the  communication  takes  ]>lacc  tnrougli  the  spaces  bounded  by  the  fibrous 
network  of  the  splenic  pulp.  Tho  blood  in  the  splenic  vein  contains  a 
greater  number  of  red  corpu«cli-s  than  the  bloocl  in  the  artery  (Mftlussex)^^ 
therefore  it  has  been  inferred  that  the  mowt  essential  function  of  the 
ajdeen  is  the  formation  of  red  corjni^clei*,  altbouj^h  the  hlood  |iigme 
found  in  the  lymph  cells,  indicale--<  llic  destruction  of  a  number  of  ihea 
elements. 

The  lymphatics  of  the  human  spleen  are  not  very  abandaitt  ;  they  ara 
found  in  the  capsule  of  the  organ,  and  also  follow  the  arteries  into  the 
substance  of  tbe  spleen.     It  is  very  probable  that  tbe  lymphatics  of  dMj 
arterial  sheaths  penetrate  as  far  as  the  Maipigbian  corj*u«Ies,  but  their 
relation  wiib  the  reticidatcd  tissue  of  tbe  spioeu  is  not  known. 

The  nerves  of  tho  splcrn,  consisting  of  large  nnvlulluted  fibres  and 
numerous  hbres  of  Kcmak,  come  fnitu  tho  sp^  ^^ic  plexus,  and  |)cnetrat 
the  organ  in  company  with  the  arteries.  Tney  may  be  followeti  upon' 
the  arterioles  as  far  as  the  corpuscles,  and,  aceonling  to  Kcker,  terminata 
in  free  extremities.

AiRopay  of  the  spleen  is  frequently  seen  in  old  persons  ;  it  generally 
is  associated  wiih  a  nbrous  thickening  of  the  splenic  capsule.  Tlie  pareo- 
chyma  of  the  organ  may  also  be  induraterl,  but  usually  it  is  of  normal 
consistence.    It  is  generally  pale,  antcinic,  at  least  when  there  has  been,

HypRn.ïMrA  of  Tnn  Splbes. — Congealloii  of  the  splcon  occurs  in  a 
nitniticr  of  very  different  Diorbid  states,  itnd  al«o  i«  tlic  first  staf^i;  of  the 
majority  of  discfiM-s  of  the  «pleen.  No  orfjan  i»  more  prone  to  c»ii)^s-

elastic  fibres  and  Hiuootli  uinsi-uUr  fn^ciciili,  is  sucii  that  it  i^nerally  r»- 
tiims  to  ita  normal  condition.  When,  however,  tlie  cause  of  the  conges- 
tion is  fre<}ucntly  repeated  or  permanent,  it  is  not  the  same,  tiiere  in 
then  a  (lennanent  increase  in  aise.  The  hyperiemia  may  be  acuta  or 
chronic. 

An  acme  t«m|)orary  congestion  occnrs  in  all  infectious  febrile  diseases, 
such  as  eniptlv«  fevers,  pyi»mia,  erysipelas,  etc..  and  in  ji  number  of  py- 
rcxiiv.  There  nociir»  in  this  congestion  not  only  a  filling  of  ll»;  ve^cls 
with  blood,  partic-nlarly  the  vein»  of  the  splenic  pulp,  but  very  prohaMy 
aldio  an  intemiption  of  the  blood-inakin;^  function  of  the  spleen,  nud  the 
I  formation  of  whlto  corptiacles  and  the  dostrticrion  of  red  ones,  beside  the 
changes  peculiar  to  each  disease.  The  precise  alteration  of  the  splenic 
blood  following  each  infections  febrile  disease  is  not  knovrn.  lu  most 
cases  of  acute  congestirc  hy|)crtrophy  Mien  in  infectious  diseases,  the 
spleen  is  soft,  and  its  pulp  is  not  of  a  iloep  red  color,  hut  is  pink,  IwcaoM 
of  the  numerous  white  corpuscle*  contnimnl  in  tlio  hlood. 

In  inlerrnittent  /ev<-rs  tJie  spleen  is  tumefied  dnring  the  fever.  At 
first,  the  hy[>enemia  passes  off  durinj;  the  apyrcxia  to  return  with  each 
access  of  the  fever.  Soon,  however,  the  tumefaction  bi'comes  permanent. 
Splenic  conxesiion  in  these  fevers  is  always  accompanied  with  destruction 
of  the  red  blood  corpuscles  in  the  spleen,  and  pigmentation  of  the  splenic 
tissue.  When  the  disease  has  continued  for  some  time,  and  a  malarial 
cachexia  snponcncs.  the  spleen  is  not  only  congested,  but  is  also  indu- 
rated, a  cirrhosis  witli  pigmentation. 

•  Tyithoiii  ffvtr  is  one  of  the  infectious  febrile  diseases  which  moat  fre- 
quently implicate  the  spleen.  This  organ  is  almost  always  hypertrophied. 
reaching  at  least  twice  its  normal  sine.  Tiie  congestive  hypertrophy 
varies:  it  may  increase  to  four  or  six  times  it»  usual  volume.  In  the 
adnlt,  the  increainc  in  size  is  less  than  it  is  in  children,  for  in  the  fonner 
the  capsule  of  the  spleen  is  denser,  thicker,  and  conseipionUy  less  ex- 
tensible. The  capsule  is  thin  and  tense.  A  section  of  tlic  organ  shows 
it  to  be  infiltrated  with  blood,  brown  in  color,  or  more  often  pink.  Hie 
ilalpighian  corpuscles  are  sometimes  very  apparent  ao<l  large,  or  ihey 
are  invisible,  a  fact  due  very  probably  to  [losi-mortem  softening.  Ttie 
coniùstencc  of  the  spleen  is  generally  less  than  normal.    AVhen  eKamined

The  number  of  lymph  cclU  coutiùnini^  red  corpuscles  is  considorahlp 
in  typhoid  fever  ;  from  a  drop  of  the  pulp  obtaiuod  by  scrapinj;,  at  loM 
one  hundred  may  be  counted. 

When  the  fever  terminât*-»  in  recovery,  the  spleen  dîminishoé  m

examination  does  nut  show  the  cells  in  a  state  of  prolifcnttiou  ;  but 
lym]>h  cells  contain  fatty  gmnules  (Fu^rKtcr^  and  red  pigment. 

The  lesion  of  the  f\Aven  m  ly|th<iiil  fever  is  therefore  not  a  simple  con- 
geflion  ;  it  scemtt  more  like  a  parenchymatous  iiiHammatiou,  a»  there  is 
a  proliferation  of  the  lymph  cell».  On  tlie  other  hand,  it  itt  not  a  simple

the  blood  is  increasei)  in  the  splenic  vein  in  the^e  di.4ea»e«,  and  there 
results  a  blood  stasia  with  congestive  hypenrophy  of  the  spleen.  Di». 
eases  of  the  heart  are  not  so  apt  to  cause  intense  hypertrophy  of  the 
spleen  as  chronic  diseases  of  the  liver,  particularly  cirrhosis.  Generally, 
chronic  congestion  is  accompanied  with  some  amount  of  interstitial  sple- 
nitis with  induration  and  thickening  uf  the  capsule,  with  or  without  [>ig- 
iDcntation  of  the  etcniunts  of  the  splenic  tissue. 

In  •■hninir  ilUfaxr  «f  the  hctrl  the  spleun  almost  always  has  its  oapsnie 
indurat<:d  and  tliickened,  and  upon  Its  iiirraee  exist  small  vegetations  with

is  normal  or  is  increased.  In  old  jientoiis  it  i«  smaller  tlian  in  middle

The  enlar^nl  arterioles,  nrterieg,  and  veina  of  the  spleen  have  their 
wall*  thickened,  indurated,  and  intiltnited  with  pipueni,  e«|M!cially  in

The  lesion  of  the  spleen  in  intermittent  fever  is  such  aa  to  essentially 
consist  in  a  destruction  of  the  red  corpuscles,  and  in  the  formation  of 

I  black  pigment  from  them.  This  change  is  not  confined  apeeially  to 
malarial  fever  ;  as  has  been  seen,  there  is  an  absorption  of  the  red 
corpuscles  by  the  white  blood  corpuscles  in  other  infectious  febrile  dis- 
eases, typhoid  fever,  for  example  ;  besides,  chronic  congestions  of  tbc^H

tnelaiueniia  or  black  ]>igmenlation  of  the  wbit«  blood  corpuscles  occurs. 

In  refieated  congestions  of  the  spleen,  and  iik  interstitial  aplenitis,  it 
bai  been  seen  that  there  occur  a  tliickening  of  the  ca|>sute,  and  a  new

mate union  of  the  spleen  with  the  neighboring  organs  by  false  membranes 
which  become  org»iii7.eil  connective  tissue.  Tiiis  Jilir'mê  pm-tplenitii

2d.  One  or  more  absoetses  of  varying  sise  have  formed  in  the  tifiaue 
of  the  spleen.  Thete  abflCCSees  are  a  result  of  traumaûi^m,  of  phlelntin 
of  the  splenic  vein,  or  they  are  metastatic  ahscossea,  or  a  conse'iuenee  of 
fevers  of  low  type  (typhoid  especially);  they  may  unite  and  form  purulent 
foci,  which  are  separated  from  the  normal  tissue  of  the  spleen  by  a 
pyogenic  membrane.  Absue^^ses  of  this  kind  may  attain  considerable 
sue  ;  tiicy  are  generally  encyatod.  and  their  pyygcnic  membrane  becomes 
fibrous.  In  some  cases  the  capsule  of  the  spleen  is  thickeneil  when 
they  are  superficial.  In  other  enxes — the  ctipctule  being  it«clf  invaded 
by  the  suppuration,  and  fibrous  arlhe«ion«  being  eittiibli^hed  with  the 
neighboring  organs — an  ab^^cesa  of  the  «pleen  may  o^n-n  into  the  stonineh, 
or  through  the  diaphragm,  Into  the  pleura  and  lung,  or  it  may  discharge 
through  the  abdominal  or  thoracic  walls.  In  some  cases  the  abscess 
communicates  with  the  splenic  vein,  and,  finally,  it  may  work  iu  way 
int«  the  sub-peritoneal  cellular  tissue  as  far  as  the  pelvis  and  open  into 
the  vagina.

D^cr  organs  ;  they  arc  met  with  in  pytemin,  in  puerperal  fever,  in  acute 

locardilis,  in  phlebitis,  etc.  They  are  I'wtited  esjiccially  at  the  ppri- 
phery  of  the  spleen,  their  hose  toward»  the  capsule.  Their  number  is 
generally  limited  ;  their  sine  varies  from  a  hemp-seed  to  a  haxel-nnt  or 
larger.  They  bejttn  by  a  small  dark-red  colored  sj)ot;  pua  is  »oon  seen

pnscles,  nhich  may  become  as  lar;;e  h»  a  haxi-l-niit  ur  walnut.  A  iiectiou 
of  the  ur<^n  shows  numerous  ;^my  or  whitifth  ikhIuIcs,  sometimes  yellow 
nt  their  centre,  and  yii-lding  a  juice  hy  «craping.  Tliu  nodules,  formed 
of  a  homogeneous  li»*uc,  are  ftt'iiaran-d  from  each  other  hy  red  xones, 
rrei[Uoiitly  s»  narrow  that  they  appear  to  touch  at  their  jieriphery.  Th« 
celliilitr  elements  oht^incd  by  scraping  the  ^i-ay  {loritons  are  lymph  cells, 
the  majority  containing  a  ^tingle  nucleus;  some.  Iir>wever.  are  larg«, 
measuring  .010  mm.  to  .020  mm., granular,  and  containing  several  round 
or  oval  nuclei. 

In  large  and  thin  sections  of  these  spleens,  examined  with  the  micro- 
«cofWftbe  whitish  nodules  are  found  to  corresiwnd  to  thcMslpighian  cor. 
puscles;  while  the  red  xotics  which  surround  them  corrcsjxtiid  to  the  tissue 
of  the  pulp.  The  hypcrti-ophied  Malpi^hiiin  corpuscles  consist  of  a  reticu* 
latc^  tissue,  with  fine  meshes  filled  with  lyinph  ctdts  and  krgc  proliferating 
cells.  The  arterioles  passiu;;  throu;;li  tiio*e  forpuscles  have  an  excessive 
infiltration  of  white  corpuscles  into  their  walli<,  s»  that  a  transverse  cut 
of  the  arterioles  shows  iheir  lumvn  »urroundi-d  hy  »  circle  of  embryonic 
tissue.  There  results  a  series  of  t<injill  t-iiihryouic  nodule»  around  the 
arteriole  which  travcnes  the  uew-f»rmed  reticutaled  ti.tsiie  of  the  cor- 
puscles. The  meshes  of  this  reticulated  tissue  are  formed  of  Bbrils, 
mostly  thickeiH-d.  In  the  central  jiortions  of  the  corpuscles,  which  are 
yellow  and  opaque  to  the  unaided  eye,  the  lymph  cells  have  undergooe 
a  granular  fatty  degeneration. 

At  the  periphery  of  the  hypertrophicd  corpuscles,  in  tlie  red  «one 
which  separates  them  from  one  another,  the  network  of  smutl  veins  ia 
seen  which  characteriEe»  the  tissue  of  the  |iu!p  of  the  spleen.  This  por-

The  elements  contained  in  these  obliterated  vessels  liave  been  taten  in 
Gcmiuny  for^innt  cellsof  a  special  nature,  and  characteristic  of  tubercle. 
Some  tJernian  writers,  howev(T,  are  reconsidering  this  wrong  inierpre- 
tatio»;  yvl,  without  any  reference  whatever  to  the  description  wo  have 
given  of  tbem,  or  notice  of  the  criticisms  upon  giant  cells  by  Thaon  and 
(irancher  iu  their  thesis  upon  tubercle. 

SYrHii.iT!c  Ti'Mons. — It  haa  previously  been  remarked  that  the  spleen 
was  hypertrophicd  in  syphilis,  at  the  period  of  sypbiltlic  Infection.  Tliis 
tumefaction  of  the  spleen  is  especially  evident  in  new-bom  children  suf- 
fering with  syphilis.  The  organ  may  also  be  indurated  and  cirrhotic, 
with  the  capsule  much  thickened,  and  covered  by  fibrous  formations:  or 
the  spleen  luay  be  in  a  stat«  of  amyloid  degeneration.  Finally,  tnie 
gummata  may  be  met  with,  which,  however,  arc  infrecjuont:  thoy  should 
not  be  coiifouiided  with  infarct!,  which  arc  also  found  in  syphilitic  persona. 

Carcinoma  op  thk  Splbks. — It  is  doubtful  if  the  spleen  is  ever  pri- 
marily affected  with  cnrciiioma.  Wc  will  not  pfisitivel/dony  it,  but  tlie 
cases  reported  as  jirinuiry  cnrriiutma  are  wonting  in  liis^lolugical  details 
Buflicieiit  to  convince  us  of  their  carcinomatous  nature.  It  cannot  be 
diagnosed  by  the  naked  eye  or  by  a  microscopic  examination  of  scrapings. 
The  stroma  of  carcinoma,  and  details  of  the  structure  of  .wcondary  fonoa- 
tioDS  in  the  glands  and  other  neighboring  organs  are  necessary  to  sup- 
port and  demonstrate  the  anatomical  diagnosis.  We  have  never  seen 
primary  carcinoma  of  the  spleen.  Secondary  carcinoma,  on  the  con- 
trary, has  Certainly  been  mot  with,  following  tumors  of  the  stomach, 


CT6TB — PARASITES    OF   TUB   BPLEES.  595 

mammary  gland,  liver,  brain,  etc.  These  formntions  are  seen  aa  nodules 
or  in6Itrations,  which  rescmhle  the  tissue  and  cellular  elements  of  the 
primary  tumor. 

Cysts. — Mucous  cysts  of  the  spleen  are  extremely  infrecjucnt.  An- 
dral  reports  a  case  where  there  existed  several  viaicle»,  which  he  com- 
pared to  cysts  of  the  neck  of  the  utema;  Leudet  saw  ii  large  cyst  divided 
into  four  or  five  compartments  by  fibrous  jartitions  lined  with  a  pave- 
ment epithelium  ;  Magilelain  reported  a  case  where  the  internal  wall  of  a 
unilocular  cyst  was  smooth  and  covered  with  hard  patches,  formed  of 
carbonate  and  phosphate  of  lime  and  magnesia.  The  fluid  was  estimated 
to  he  about  3  litres,  of  a  yellowiah-brown  color,  albuminous,  and  contained 
lymph  cells,  red  blood  corpuscles,  and  eryatala  of  cholcsterin.  Fœrster 
mentions,  in  the  collection  at  WBrtzburg,  a  serous  cyat  of  the  spleen, 
as  large  as  a  hazel-nut,  with  curtilage -like  walla.  The  mode  of  develop- 
ment of  these  tumors  is  not  known. 

Andral  reports  having  seen  a  dermoid  cytt  of  tlie  spleen,  containing 
fatty  material  and  hairs. 

Parasites. — Single  or  multiple  cysts  in  the  spleen  containing  echino- 
cocci  have  bece  very  rarely  met  with.  The  hydatid  sac  may  be  the 
seat  of  daughter  hydatids,  as  in  the  liver.  They  are  most  frequently 
developed  in  the  peritoneum,  which  covers  the  organ,  and  are  pedun- 
culated, projecting  into  the  peritoneal  cavity.  They  are  generally  seen 
in  connection  with  analogous  productions  of  the  liver  and  peritoneum. 
E.  Wagner  has  seen  an  example  of  Pentastomum  denticulatum,  surrounded 
by  a  calcified  cyst,  in  the  human  spleen.

In  many  other  cjikch,  t)ic  capitlnry  vCMelii  and  small  arteries  are

of  fnsifonn  celU. 

The  change  from  the  normal  follicles  to  those  most  altered  «us  easily 

I  followed.     The  celt!»  in  tiic  normal  follicles  were  hypt-rtniphird.  the  col-

and  liiiaily  hecame  ahsoihed.  nhen  the  epithelial  cells  had  beeoine  very 

large  and  wen.-  tletached  from  the  wall  and  set  free  in  (hf  cavity.     TIiom 

altered  follicles  formed  islands,  in  which  the  degenvralion  wm  visible  lo 

the  unaided  eye;  hut  even  in  those  islands  which  were  moM  disewwd, 

almost  normal  follicles  could  he  found  which  Mill  contained  the  eolloid 

■  substance,  and  in  wliich   the  celU  «ere   .«li^^htly  liyfiertrophied.     The 

[  eeptum  of  celluto-fihrous  tiȉiie  separating  two  alveoli  iVeH|ueiuIy  had  upon 

[  one  side  a  row  of  normal  or  almost  normal  cells,  and  opoo  the  other  side 

a  row  of  large  cells. 

This  mode  of  development  of  the  tumor  is  allied  to  carcinoma  of  the 
lung,  in  so  far  as  concerns  its  origin  from  the  pre-exisling  epithelial  eells 
i»  the  normal  cavities  of  the  org/m.  The  vegi-lHlion*  which  projwi  inio 
the  interior  of  the  follicles,  and  ;vhicb  are  covered  with  m-w  celU,  are 
analogous  to  those  ohsenc'l  lu  the  galactophorou*  duct«  included  in 
tumors  of  Uie  nuimmary  gland. 

In  re^tartl  to  the  nnture  of  the  tumor,  we  consider  it  an  epithelionia, 
in  which  the  hypertrophted  p  re-ex  idling  and  ahundant  cells  are  cylinilri- 
cal  when  in  place,  hut  irregularly  polyhedral  or  round  when  free.  As 
the  neoplasm  of  the  connective  tiii.^ue  does  not  form  inbes  lined  with 
cylindrical  cells,  hut  consistai  simply  in  an  inliltraUon  of  large  cells  be- 
tween the  connective- tisdue  fibres,  it  cannot  be  considered  a  cyliudrical- 
oolled  epithelioma.  On  the  other  hand,  it  is  difficult  to  class  th»  tumor 
as  n  carcinoma,  since  the  new  formation  of  connt-citvo  tiasue  does  not 
have  the  regular  appearance  of  the  stroma  of  carcinoma.  It  la  a  variety 
of  epithelioma  intermediate  between  the  ty]ies  which  we  have  oscd 
establish  the  elassilication  of  tumors.  It  is  well  known  iJtat 
LMOlated  cases  of  tumors  cannot  be  placed  under  the  dcjuriplion  of  a 
^definite  type;  they  establish  the  connecting  tiiika  between  one  variety 
and  another.

still  exist  concerning  the  nature  of  iho  dtseaac. 

In  this  stale  the  gland  is  increased  in  sixe  ;  it  may  reach  twelve

anœmia  aocl  the  digeative  disturbances.  The  physiological  explanations 
vhich  have  been  given  are  far  from  satisfactory.  The  leaiona  of  the 
nerve  centres  of  the  supra-renal  capsule  and  of  the  great  sympathetic 
probably  in  part  account  for  the  phenomenon  of  pigmentation.  It  is 
also  to  be  remembered  that,  very  frequently,  leaiona  of  the  capaulc  are 
found,  9uch  aa  cancer,  tuberculoais,  and  even  a  caaeous  inflammatory 
state  to  an  advanced  degree,  without  the  skin  being  pigmented.  Accord- 
ing to  Klebs,  in  141  casea  of  lesiona  of  the  supra-renal  capsule,  the  skin 
was  colored  in  100,  and  in  the  remaining  41  no  coloration  was  present. 

But,  on  the  other  hand,  Addison's  disease — when  it  has  been  care- 
fully distinguished  from  the  melanccmia  of  intermittent  fevers,  and  from 
the  cachexias  with  cutaneous  pigmentation  of  tubercle  and  cancer — is 
associated  almost  invariably  with  a  very  decided  lesion  of  the  aupra- 
renal  capsule. 

The  changes  in  the  other  organs,  observed  in  Addison's  disease,  are 
very  varied  and  multiple  ;  but  pulmonary  tuberculosis  and  scrofula  are 
most  frcijuently  met  with.

Such  is  the  course  of  11  uriniferous  tubnte.  The  relations  between 
the  cortical  and  medullary  anbslance  of  the  kidney  may  now  be  consid- 
ered. The  collectînî;  tubules  eniptyin;;  at  tlie  papilla  ascend  and  divide 
as  far  aa  the  cortical  subittance.  where  thoy  send  off  the  straij^ht  tubules

secondary  pyramids  as  there  arc  medullary  rays. the  base  of  these  pyramid* 
bein^  turned  towar»!î  the  periphery  of  the  kidney. 

The  bloodics.tels  present  »  special  distrihutinn.  The  rctinl  artery 
enter»  at  the  hilui,  and  there  divides;  itJt  division»  run  between  the 
pyruinids,  and  give  off  branches  at  tlie  boundary  between  the  cortical 
substance  and  the  pyramid»,  at  the  ba«c  of  the  latter.  The  intertubnlar 
arteriKit  ari^c  at  this  point,  pass  directly  into  the  cortical  substance  per- 
pendicular to  the  surface  of  the  kidney,  in  their  course  i;ivin;(  olf  at  inter- 
val* arterioles  wiiieh  enter  into  the  Mal)>i;^hian  tufts.  The  afferent 
vessel  of  the  glomerulus  divides  into  a  number  of  secondary  branches, 
each  presenting  fi'ee  loo|)i  upon  the  surface  of  the  glomerulus.  The  vea. 
acts  proceeding  from  these  subdivisions  are  united  into  a  sîntflo  trunk 
(oSeretit  vessel),  which  passes  out  of  the  glomerulus  alon^de  of  Ihe 
«Seront  vessel. 

In  the  ijlomernlu*  the  small  vessels  possess  a  membrane  containing 
iiuck'i  like  the  capillaries.  These  vessels  arc  covered  npnn  their  cxt«r- 
nid  surface  by  Hut  cclN,  so  that  the  cavity  of  the  glomerulus  is  a  closed 
cavity  lined  thrf"i;;houl  with  cells. 

The  efferent  vessel,  after  pas*inj:oiit  oP  the  glomerulus,  is  separated 
into  capillaries,  which  w*  a  fine  network  surround  the  glomeruli  and 
uriniferous  tubules.  In  the  same  re[:ion  that  the  inlertubular  arteries 
are  given  off  to  the  cortical  substance  at  the  base  of  the  pyramids, 
the  renal  arteries  glie  off  other  very  small  arterioles,  wliieh  pursue 
an  opposite  course,  and  descend  into  the  pyramiils.  These  arteries  are

unie  in  this  region;  here  alone  the  ;;Kimeruli  are  located:  in  tli<r 
tnbules  of  tliis  substance  are  elnboraleil  the  materials  which  are  swept 
away  by  the  current  of  Buid  coming  from  the  glomcrulns.  Thus  is  ex- 
plained the  pbyHioloi^ictil  function  of  tbc  kidney:  it  i»  almost  always 
affected  by  patboiopcid  modificationc  of  the  orj^an,  which  in  the  cortkal 
suliiitance  acc{mre  tbeSr  ^reaieiit  intenitity  mid  Treipiency.  Althmigli  it

with  which  it  is  immediately  continuous. 

The  t_^mf'luitie  canal»  of  the  kidney  are  readily  injected  and  demon-

these  canals  penetrates  into  the  entire  orjian,  even  into  the  gmiimc- 
tivc  tissue  surrounding  the  uriniferous  tubules.  In  tiie  kidney,  as  in 
connective  tis:>iie  in  ^-neral.  it  is  difficult  to  separate  the  study  of  the 
lymphatic  xy^itein  from  that  of  the  connective  tissue.  Ilie  connective 
tissue  of  the  kidney  is  unei|ita1ly  distributed;  llie  fibrous  eaf^utule  in 
formed  of  fasciculi  uf  iiiterlacin<;  fibres,  and  »eiids  fibrous  probxij^tioii», 
which  accom)i»ny  the  vessels  of  t)ie  cupi>ute  into  the  cortical  sulistauce  of 
the  organ.  The  capillary  vessel»  of  the  connective  tis;<ue  olTer  little  re- 
sistance to  ibe  iieparaiion  of  the  capsule  from  the  kidney.  At  the 
apex  of  the  Maipi>;hian  pyramids  the  eonuective  tisane  is  quite  ihick, 
and  easily  de nionxt rated  ;  here  the  wall  of  the  collecting  tubules  is 
foiroed  by  this  tissue,  not  having  any  iiiter])Ofled  membrane  between  it 
and  the  lininn  cpitlieliuni.  Surrounding  the  glomeruli,  there  is  also  a 
very  distinct  layer  oi'  connec6vc  tissue.  Throughout  the  remaimng  por- 
tion of  the  orj;an  ibe  sti'ucture  supporting  the  vessels  and  surrounding 
the  uriniferouK  tubules  is  very  delicate,  and  is  blended  with  the  vessels.

consi->iuence  of  an  obstacle  situated  at  some  [loint  altm;^  iho  course  of

of  Bright'.*  dÎHoa.te,  and  in  every  minaient  albuminnu^  nephriti.-'.  If

nuclei  are  present, and  there  frequently  remain  small  fatty  gr.inidcs  in  the 
C4'll.  Fatty  !;ninules  in  the  renal  cells  do  not  exist  in  the  norniiil  state 
either  in  tlie  child  or  adult,  nUhon';h  they  aro  found  physioloipciilly  in

catarrhal  or  albuminous  nephritis,  of  varyin;;;  intensity,  which  invoices 
the  escape  of  albumen  into  the  urine.  In  certain  poiaonings  (photi|>honiB,

Uy  virtue  of  thcxo  olemcntiry  le:«ions.  which  belong  to  tlie  intlamma. 
tory  procesa,  there  is  a  series  of  moililîcationa  which  result  from  otian|R« 
in  nnirition  of  the  cells,  or  their  intillntiion  by  different  aub-ttaiwe*. 
Thus,  ill  overv  case  of  iotcnis,  whjilever  may  be  the  cause,  there  are 
found  in  the  kidiicy  mmie  i>f  the  uriniferoitg  tubule»  who»e  cells  contain 
yellow  or  gi-cenisU-ycllow  granules  powesnin;;  the  renctious  of  biliary

the  interior  of  the  tubule^  or  they  form  eloii'^ted  inaKseit  moulded  in 
the  cavity  of  the  tubules.  When  bile  ia  jireM-m  in  lar^ie  amount  in  tha 
kidney,  crvsLil*  of  bilirubin  are  found  either  in  tlio  l-vHh  or  in  llie  oon- 
nective  liiviue.  I'nder  other  circumatanccs.BaUsiufiltraie  tlio  renal  cell*; 
the  latter  become  centres  of  crysUtllization  and  of  microscopic  or  lar^r 
calculi.  This  occurs,  for  example,  in  newly-born  children,  when  the 
renal  parenchyma  is  oli4triicb>d  with  umtcof  soda,  or  when,  in  the  goulT 
diathesis,  the  same  salt  infiltrates  the  cells  of  a  number  of  tubules  and  is 
dcpo-xitcd  in  the  form  of  needle-like  crystals. 

The  ealcarcons  Halts,  alkaline  carbanntt-s  and  phosphate-*,  also  may  bo 
deposited  in  the  epithelial  celU  of  the  oafisule  "f  the  glouienili.     Tlie 

latter  appear  in  the  cihape  of  small  ojiaqtie  and 
hard  granulea  upon  the  surface  of  thf  kidney, 
where  they  are  scarcely  vUihIe  to  tJie  unaided 
eye.  Fnrihcr  there  are  found  up<*n  the  surface 
of  free  cells  in  the  urinitcrous  tubules,  crystal* 
of  the  tribuic  phoaphates  or  of  the  oxalate  of 
lime. 

Tlie  cells  of  the  kidney  may  atrophy  aikd  be 
destroyed.  For  example,  in  a  renal  infarciai. 
when  tiie  circulation  of  tlie  blood  is  arrested  in 
a  part  of  tlie  organ,  as  in  a  raetnstatic  absceas, 
the  cells  become  fatly  and  hreiik  up  into  jtrao- 
ular  molecules.  When  a  purtion  of  the  kidney 
is  compreitsed  by  a  pelvic  calcul»*,  or  in  chronic 
pyelitis  with  retention  of  urine  and  distension 
of  the  calyces  and  pelvis,  the  atrophied  tubules  contain  only  small  or

tissue  of  the  kidney  ia  not  very  abundant,  yet  it  is  certainly  present, 
eapeeially  in  the  parts  that  have  been  mentioned. 

The  lesiana  which  this  tissue  undergoes  in  nephritis  arc  varied,  accord* 
ing  to  the  cause  of  the  disease.  In  simple  con;;e«tion,  tbo  cells  nf  tbc 
connective  tissue  consume  a  greater  amount  of  nourii^ing  fluid  than  in 
the  normal  state  ;  their  nucleus  becomes  larj^er;  the  proloplasm  of  the 
cell  is  granulhr  and  distinct;  Uie  entire  cell  is  enlarged.  If  the  con-

in  lesions  of  the  mitral  vaUe,  an  extravasation  of  tlic  coloring  uialerial 
of  the  bloû<l  may  be  manifested  by  pigment  granules  around  the  cells  in 
the  fibrous  stroma  of  the  kidney.  Almost  always,  in  these  cases,  the 
connective  tissue  cells  proliferate  and  increase  in  number.  The  inter- 
tubular  septa  are  therefore  increased  in  thickness.  The  cellular  elements 
which  compose  them  belong  to  the  cells  of  the  connective  tis-tue.  The

nephritis  are  often  encountered. 

From  the  above  descriptions,  it  is  evident  that — although  relate*!  by  a 
common  symptom  and  a  common  lesion,  namely,  the  presence  of  albutMB 
in  the  urine,  and  the  fatty  dc;;eneration  of  the  cell* — jmro  itch  y  matons

observed  in  all  the  chronic  discjv.M^>s  due  to  a  variety  of  cauncs. 

After  Brighl's  discovery  (l*^iI7).  patholofiisln  were  inclined  to  regard

are  not  chemically  composed  «f  fibrin  oppose»  tlie^ie  views.

vhich,  both  strni';ht  and  convoluted,  are  tilled  with  fatty  granular  dcgcD-

Burroundin;r  thorn  upon  the  Kurfflec  of  the  kidney  is  composed  of  atrophied 
nod  fibrous  glomeruli,  and  of  a  fe«r  atrophied  convoluted  tnbtdes  near  the 
glomeruli.  The  connective  tissue  enveloping  tlicse  glonKrutt  and  tuhuhni, 
on  the  contrary,  is  thickened,  as  in  intcrstitiiil  nojihriti*.  The  MtrD|>tiied

The  cortical  substance  is  partially  or  entirely  atroijliied.  It  is  verr

Wo  have  recently  studied  six  specimens  of  amyloid  kidneys,  hnvin;; 
colored  them  with  the  violet  of  nietliylaniliiic.alW  |>reservation  in  alcohol. 

In  three  of  these  kidneys,  the  amyloid  ehangc  was  very  extJinsivo; 
all  tbe  arteriole!*,  the  ghmieruli,  tbe  «mall  reiuf,  the  hyaline  wall  of

meruli,  the  walls  of  the  vessels  wore  very  tliick  and  stained  red.  The 
I^aioi)  attacked  their  inner  layers  ;  the  connective  tissue  uniting  thes« 
vessels  showed  its  fibril*  ami  cells  colored  blue.  The  Hat  cells  which 
eoTered  the  vascular  )oo\»s  of  the  jçlomendi  were  nomuil  and  blue. 
The  cells  lining  the  capnulo  «f  tbe  glomcrubw  were  nnnniil  and  verj- 
distinctly  blue.     The  eajwular  mcinbriiiu'  it.<elf  was  j^-nerally  nnnnal. 

Transverse  ttection.t  of  the  arteriolei)  abovred  their  endotbt'liitai  very 
distinct,  uoi-mal,  an<t  blue  in  color.  In  all  the  emiothelial  cells  of  the

fibres  of  the  middle  eosil  were  colored  red  ;  the  former  wer©  swollen.  Whca 
the  lesion  was  not  so  far  advanced,  only  the  internal  coat  was  degenerated. 
The  external  coat  is  usually  not  ini|)lieutcd  :  its  vonncctjve-tissue  cells  and 
fibres  were  colorei)  blue.  Yet  sometimes  a  few  fibres  colored  red  wera 
seen,  while  the  comioctive-tiswue  cell*  retained  their  blue  color.  The 
lesions  of  the  jimall  veins  of  the  pyimmidit  are  nnnlogous.  and  arc  well 
marked.  Their  endothelium  is  preserved  intact;  tbe  reii  blood  conmseles

but  tbU  thickening  by  amyloid  degeneration  is  much  luatv  deeideil  i»

thelium of  the  vessels,  as  well  a^  the  epithelium  of  the  urinifoTOus  tubules 
and  of  the  tnciobranes  of  the  glomeruli,  arc  not  iavolvcd  in  the  amyloid

fatty  condition  of  the  cpiihclial  cells  of  the  renal  tubules  in  several  ant-

Wo  have  previously  seen  that  in  some  case»  of  pit roneliy matous  nephritis 
there  is  a  im>w  formation  of  small  cvlh  and  nuclei  in  the  vascular  tuft  of 
the  glomerulus,  either  at  it*  centre  or  nijou  the  vascular  loojw.  When 
tliis  foniuttion  is  very  abundant,  the  vascular  loop»  ure  nut  iwparale; 
they  fona  a  compact  ball,  in  which  the  .^inall  vessels  of  the  jrlomerulu» 
are  fuaed  together  by  an  embryonic  connective  tissue  inlillrated  with 
lymph  celU.  This  condition  baa  been  well  described  by  Klobs  in  scar-

the  j^lomeruli,  the  connective  tissue  surrounding  them,  and  that  scpantt-

grailuallv  alroiihie»,  and  refircsontâ  at  linies  an  almost  honio^îi-mviug

|Çninn1i-s.  Krfi|ueiitly  tho  entire  cavity  of  the  cajMulc  is  distended  and 
fiUed  with  granules  of  this  nature. 

The  whole  of  the  glomerulus  now  appeara.  to  the  anaidcti  eye,  ns  a

round,  dark,  and  opaiiuc  mass,  which  efforv-csces  upon  the  addition  of 
acetic  acid. 

Almost  all  the  glomeruli  are  more  or  less  altered,  and  the  (ubules 
proceeding  from  them  undergo  an  analogous  atrophy,  while  the  eotntec-

with  the  other. 

8»nietiinea  glomeruli  are  seen,  Uie  vesseU  of  whicli  are  atrophied, 
while  tlie  ca]»ular  canity  is  filled  hv  a  colloid  substance.  These  are 
colloid  cyatA  developed  in  a  gloiDcrulus.  In  these  cysts  there  still  re-

diSicuIty  of  the  circulation  in  the  kidneys  and  a  consequently  increftud 
pressure  in  the  aorta.  In  all  the  caacs  of  atrophied  kidneys  that  wo  have 
examiocd,  wo  have  always  seen  in  some  of  tbc  tubules  less  atrophy  than 
in  others,  and  a  grannUr  fatty  degeneration  of  tbc  epithelium,  similar 
to  that  observed  in  parenchymatous  nephritis.  Ctinsci|ucntly  in  ibvsc 
two  varieties  of  albutnimnis  nephritis  there  is  an  alleration  of  the  reiiiil 
epithelinni  common  U»  both.  Ti>  distinguish  between  iuterslitial  nephritis

of  tlic  tubule»  U  primarily  granulo-fatty,  and  the  surface  of  die  organ  is 
smootli.  The  symptoms  diller  aUo,  fur  in  ihe  latter  the  course  of  tlie 
disease  is  more  rapid,  the  alhumiuttrla  is  very  abundant,  the  iiuantity  of 
urine  is  less  than  normal,  and  the  <»<lema  is  always  very  decided. 

The  preceding  facts  appear  to  be  well  establtshed.  and  the  two  distinct 
groups  of  symptoms  correspond  with  two  well-established  distinct  lesions. 
But  before  concluding  from  these  syndromes  two  distinct  diseases,  or 
even  two  distinct  varieties  of  the  same  (Uright's)  disease,  it  is  necessary 
to  be  certain  tliat  tbc  granular  contracting  kidney  never  begins  in  parca-

is  difficult  to  understand  from  the  descripdons  of  autopsiées  given  by

evidently  has  existed  a  lon^  time,  while  the  atrophied  and  granular  kid-

of  the  pro'lucinjf  cau'e  and  of  the  lesions  which  are  tbeconseipieuceof  it.

'  which  di'vclojw  t|uickly  and  tenninatett  in  death.  At  the  autopsy  there

AVheii  the  exciting  cause  is  slow  in  it»  action,  for  example  alcoholism, 
wo  may  have  cither  a  nmooth  kidney  or  an  atrophied  and  granular  kid- 
ney j  Ôie  lesions  being  limited,  and  slower  in  their  changes,  the  connec-

the  canse  is  constitutional  and  \'err  slowly  developed,  a»  gout,  the  lesions 
will  be  limited,  and  at  iirsl  not  very  intense,  and  a  tyjMcal  granular  con- 
tncting  kidney  will  be  found  at  the  autopsy.  Itut  it  should  be  rcmeo-

and 'calyces*  hy  pus  for  one  or  more  atiscesses  of  the  kidney,  'ilie  dia- 
t«n:<ii)n  of  the  jielvis  and  ureter  may  secondarily  occasion  an  atrophy 
of  tlie  entire  kulney,  whose  siihatance  then  fonns  the  wail  of  a  wic  filled 
with  pus.  When  atisoessea  of  the  kidney  are  very  large,  they  an-  );ene- 
rally  connected  vich  a  suppuration  of  the  pelvis.  Tnie  atiscewes  in  the 
.  kidney  are,  however,  quite  frc(|uont  in  suppurating  pyelitis,  which  ig  lui

The  sujppuratin;;  foci  of  the  kidney  have  variable  terminations.  When 
only  the  apex  of  the  pyramiils  is  involved,  the  foci  may  ulcerate  and  form 
irregular  ulcers,  which  freely  discharge  into  the  pelvis.  C'vstê  or  cica- 
trices, followed  generally  hy  atrophy  with  a  condensation  of  the  organ,

pus,  ammoniacal  products,  inspissated  pus,  soft  white  calcireous  matter, 
and  calculi.  The  submnciuis  tissue  is  thickened,  and  the  tumor  contracts 
adliomoRs  with  the  surroiindinj;  orjçans.  The  secreting  structure  of  the 
kidney  is  naturally  atrophied,  spread  out.  and  flattened,  so  as  to  form  the

Sarcoma. — We  know  of  only  two  cases  of  sarcoma  of  the  kidney. 
Tlifse  cases  were  tumors  of  consideralile  .siée,  occnning  in  younj;  chit- 
dreii.  The  centre  of  these  enonuoiis  ajiherieal  tumors  was  softenetl  in 
one  case;  there  vas  considerable  infiltration  of  hlood  into  the  substaiKo 
'Mid  into  the  lacunie  of  the  sarcomatous  tissue.  The  renal  capsule  which 
1  everywhere  surrounded  tlic  tumor  was  tbiekcned.  The  kidner  was 
flattened  upon  the  surface;  imdcr  the  capsnle,  at  some  points  it  showed 
to  the  unfii<led  eye  and  to  the  microscope  the  appearance  and  simcnire 
of  the  cortical  substance.  The  sarcoma  was  eertjiinly  developed  in  the 
suhstanue  of  the  pyniniid?!,  at  the  [loint  of  union  with  tiie  vortical  mib- 
fltance.  The  central  part  was  soft  and  friable,  showing  all  tlic  charueterv 
of  round  celled  sarconix,  with  vesseU  liiivin;*  enibryoïiic  nails  in  one  of 
the  CMW»,  and  fascicular  (spindle-cell)  sarc"ni:i  in  the  other.  In  lioth 
leases  the  dt'velopment  of  the  sarcimia  could  be  followed  from  the  eenlre 
to  the  periphery.  In  the  fascicular  sai-coma  it  liad  extonded  into  the 
cortical  suhntince  along  the  coarse  of  the  arterioles.  The  circumferei»ce 
of  tJie  vessels  and  the  iH'i;;ht>orinj;  connective  tissue  around  the  urinifer- 
Otis  tubules  exhibitc<l  a  new  formadon  of  round  or  elongated  cells,  with 
fusiform  nuclei,  interjjoiwd  hc-twcen  the  fibres. 

In  the  second  tumor,  the  ptirticipntion  of  the  cells  contained  wittiin  the 
nriniferoua  tiibuU'S,  in  the  lonnalion  of  sarcomatous  tissue,  could  eery 
easily  be  sludied.  The  elements  of  the  tumor  were  developed  both  in 
the  connective  tisauc  ami  in  the  inteiior  of  the  uriniferous  tubolea.    Upon

are  fatty  dcj^eny rated,  and  the  hloodveHselii  art'  ;çrputly  congcutwl.  Keiixt 
bemorrbafîes,  a  fn'(iuent  symptom  of  these  tumors,  occur  on  account  of 
this  extreme  congestion  of  the  ronal  sulmtancc,  aa  well  aa  from  the  carci- 
uomatous  now  lormatioitH  ujion  the  siirtaeo  of  tbe  pelvis  and  calyces.  In 
portions  where  tbc  tumor  invades  tbe  normal  tissue  by  extension,  Wal- 
devor  has  isolated  cylinders  of  epithelial  ceils  growing  from  the  nrinifcr- 
ou*  tubules,  and  extending  by  diverticulse.  Robin  bad  indicated  tbe 
metboil  of  devetojinent  »f  epitlielioma  by  a  now  formation  of  renal  epi- 
tlielinm;  but  he  ODnfounded,  under  the  iinmc  of  cpithetiomata  of  the 
kidney,  not  only  carcînomntu,  but  also  other  lesions  i>f  the  kidney,  par- 
Ucularly  Brijrbl's  disease.  AOer  the  invoJttiïations  of  Waldcyer,  ob- 
servations publl-ibed  by  Neumann  and  others,  have  oonfirmeil  the  inoilc 
of  development  and  extension  of  the  tumor  by  budding  of  the  epithelial 
cells  of  the  uriniferoua  lubules.  What  we  knovf  of  the  developiuent  of 
tiitiiors  in  glands,  and  nbal  we  have  described  relstire  to  tlie  origin 
of  renal  surcoma,  incline  ns  to  believe  that  the  epithelial  cells,  as  well 
OS  the  connective  tissue,  participate  in  the  development  and  citeusion  of 
carcinoma. 

Tbe  structure  of  the  tumor  doc»  not  differ  from  the  descriptions  given 
of  thv  several  varieties  of  careinomnta.  A  pecnliiirity  of  bmmaboid  CD- 
cepbaloid  of  tbe  kidney  is  marked  by  the  presence  of  very  numerous, 
enormously  ilikited  eapltlary  ve.-^-'els.  Tbe  renal  vein  is  «omelimes  the

intlammnlion  or  an  extension  of  a  catarrhal  inflammation  of  tbe  urinarj 
passa  i^es. 

Another  variety  of  chronic  orchitis  consists  in  a  chronic  inflammation 
of  tlie  interstitial  tissue  of  tho  testicle.  The  size  of  ttie  organ  U  aonw- 
times  increased,  sometime»  normal  or  even  diminiabed.  Seldom  ia  an 
atrophy  of  the  substance  of  the  testicle  observed.  Sometimes  this 
chronic  Inflammation  ta  aceomjtanied  with  a  aup]mration  which  occasions 
the  formation  of  one  or  more  abacesses.  'Hie  ahsce«te»  may  remain

Miniiiiferons  tubes  are  found  surrounded  by  granulation  tissue.  The 
gnnalations  consist  of  embryonic  tissue.  The  lesion  is  termed  benign 
funffus  of  the  testicle.  T'le  mass  gradually  diminishes  through  suppura- 
tion, and  recovery  takes  place  by  the  formation  of  a  cicatrix. 

The  surface  and  connective  tissue  of  the  epididymis,  as  well  as  the 
serous  membrane  of  the  testicle,  may  be  the  seat  of  chronic  inflammation 
with  an  abundant  formation  of  embryonic  tissue  ;  the  latter  may  pro- 
liferate and  form  elevations  like  the  granulations  of  fungus  of  the  testicle. 

The  granulations  of  embryonic  tissue  formed  upon  the  tunica  vaginalis 
after  gangrene  of  the  scrotum  should  not  be  confounded  with  benign 
tanjças. 

Benign  fungus,  that  is,  hernia  of  the  inflamed  substance  of  tlie  testicle, 
in  which  the  connective  tissue  of  the  testicle  is  changed  into  granulation 
tissue,  occurs  under  various  circumstances  :  in  acute  purulent  inflamma- 
tion when  an  abscess  has  been  opened;  in  tuberculous  orchitis,  and  at 
times  in  syphilitic  orchitis. 

St/philittc  chronic  orchitis  consists  in  a  new  formation  of  fibrous  tissue 
between  the  seminiferous  tubes.  The  tubes  are  separated  from  one 
anotlier  by  embryonic  or  fibrous  tisane,  and  are  atrophied  by  pressure.  In 
some  oases  they  are  almost  reduced  to  their  enveloping  membrane,  and 
have  in  their  interior  only  a  few  atrophied  granular  fatty  cells.  This  lesion 
may  affect  either  the  entire  testicle  or  only  a  few  lobules.  A  thickening 
of  the  tunica  albuginea  and  tunica  vaginalis  is  also  observed.  The  tunica 
vaginalis  may  present  either  vegetations  or  adhesions.  This  variety  of 
orchitis  usually  coexists  with  syphilitic  gummata,  but  may  occur  without 
them. 

Htdrocblb.  Hydrocele  of  the  Tunica  Vagittalis. — Although  hydro- 
cele of  the  tunica  vaginalis  has  been  placed  among  the  dropsies,  it  should 
be  considered  aa  a  chronic  inflammation.  The  lesion  seldom  occurs  in 
general  dropsy,  and  the  fluid  in  the  tunica  vaginalis  contains  a  consider- 
able quantity  of  fibrin,  as  occurs  in  all  inflammatory  exudations  ;  fre- 
quently there  are  formed  fibrous  productions,  new  membranes,  and  ex- 
crescences upon  the  internal  surface  of  the  serous  membrane.  This 
disease  is  characterized  by  a  serous  or  fibrinous  exudation  into  the 
tunica  vaginalis,  resulting  either  from  an  acute  or  a  chronic  inflammation 
of  the  whole  serous  membrane  or  from  a  varicocele.  The  amount  of 
fluid  varies;  it  is  generally  clear;  at  tiroes  colored  yellow  by  a  few 
blood  corpuscles  ;  there  may  be  present  crystals  of  cholesterin,  swollen 
endothelial  cells,  and  enough  lymph  cells  to  give  it  a  turbid  appearance. 
In  some  cases  of  hydrocele  there  exists  a  cyst  of  the  epididymis,  which 
may  rupture  into  the  tunica  va^nalis  ;  in  the  latter  case,  spermatozoida 
are  then  found  in  the  fluid  of  the  hydrocele. 

The  internal  surface  of  the  tunica  vaginalis  in  recent  cases  is  smooth, 
but  the  connective  tissue  of  the  membrane  is  always  thickened.  Id 
chronic  hydroceles  there  are  always  found  very  evident  signs  of  chronic 
inflammation;  there  are  superimposed,  upon  the  surface  of  the  tunica 
vaginalis,  either  the  parietal  or  the  visceral,  layers  of  new  vascular  mem- 
branes.    These  formations  usually  consist  of  a  dense,  hard  connectire

Or  contusions,  to  which  tlicse  largo  tumors  arc  exposed,  there  may  occur 
an  osaipo  of  blood  into  the  cavity  of  the  tunic*  vaginolis.  The  tumor 
fornH-d  by  [his  blood  \t  dense,  ham,  and  non-fluctuatiiie  ;  the  cavity  of 
the  thickene<l  fibrous  tunica  vaçinulîs  îs  filled  with  a  chocolate  orhrowii 
fluid,  a  color  <Uie  to  tlie  presence  of  Jisint<'{;niliiif;  blood  coqmscle*.  I'pon 
the  fiurface  of  the  membrane  and  in  the  sac,  blood  clots  and  coagulated 
fibrin  arc  seen.  Microscopic  examination  of  the  fluid  shows  fibrin,  red 
blood  corpuscles,  swollen  endotlielial  cells  containing  blood  pigment,  fat^ 
gmnules,  and  frefin«>ntly  also  crystals  of  cholestcrin.  If  the  escape  of 
blooil  occurs  when  there  has  previously  been  a  large  amonut  of  tho  serous 
fluid  of  a  hydrocele,  there  U  no  coagulation  of  the  fibrin  in  (ho  fiiiid  of

layers  of  new  membrane.  An  ewape  of  blood  may  also  occur  in  a  cy8t

InliltraiioHS  of  blood  into  the  connective  tiaaue  of  the  testicle  are  of

tions wit),  in  the  fiiluro,  determine  a  distinction  between  them. 

Malasscz  has  recently  published  some  obaenations  upon  this  subject, 
in  which  the  cystic  formations,  sitaai«d  in  the  centre  of  the  lexticle,  were 
BCparattd  from  tJie  parenchyma  of  the  tc«tjc1e,  which  was  pushed  to  the

\>y  an  almost  normal  connective  tissue,  which  contained  a  few  lymph  cells

pcomc  spherical  and  undergone  a  fatly  degeneration.    In  no  part  couhl 
MnlaMez  discover  a  change  of  the  normal  seminiferous  tubes  into  cysts; 

Pmreover,  the  cy*ts  had  no  similarity  lo  the  seminiferous  IiiWs.  Heiu-c

or  vrins  of  the  cord  occur. 

I      Chromc  Orckitik. — There  arc  sercral  varieties  of  chronic  inflan». 

HÉMion  of  t!ic  testicle.  It  may  invade  at  the  same  lime  both  the  tvfticle 
and  epididymis,  whicJi  are  increased  in  sixe.  Accortiinj-  lo  the  de»cri[v 
tion  of  Fœrsier,  the  lesion  consists  of  an  enlargement  of  the  aeminiferoua 
canals  by  the  cells  forming  in  greater  abundance  than  in  t)ie  normal  state, 
and  by  an  infiltration  of  all  the  cellular  tissue  iritli  an  infiammatory  exa- 
dation.  The  fibrous  trabuculfe  are  thickened  ;  the  testicle  and  epididy- 
mis arc  iudurntcd  and  bosscllated.  Upon  the  cut  surface  the  thickened 
fibrous  InibecuW  arc  visible,  and  bctirccn  tliem  a  yellow  homogooeous 
caseone  ma»s  ('istwus  ovkiti»)  U  twn,  îu  which  traces  of  the  seminifer- 
ous lubes  arc  only  occnMonally  found.  Tliis  lesion  has  some  rceemblnDce 
to  tuberculosis,  with  which  it  is  fre'iumidy  confoundcfl.  According  to 
Virchow,  it  has  no  connection  with  tubcirulo^i»,  but  fitllows  a  traumatic 
inflammation  or  an  extension  of  a  catarrhal  inflammatioD  of  the  urinary 
passages. 

Another  variety  of  chronic  orchitis  consistai  in  a  chronic  infianimatM» 
of  the  interstitial  tissue  of  the  testicle.  The  sixe  of  the  organ  is  some- 
times increased,  somctimea  normal  or  even  diminished.  Seldom  is  an 
atrophy  of  the  substance  of  the  testicle  olxsened.  Sometimes  ilus 
chronic  iuflammution  is  accompanied  with  a  auppuratioD  which  occasions 
the  formation  of  one  or  more  abscesses.  The  ilocesses  may  remain 
stationary  and  be  surrounded  with  u  fibrous  or  calcified  encysting  mem- 
brane ;  »r  they  may  extend  and  ojien  spontaneously, 

By  a  solution  of  coniinnity,  a  hernia  of  the  testicle  may  occur  exter- 
nally as  a  sjioii;^-,  vascular,  and  grauulating  aam,  in  nhtcii  the  alteivd 


HYDROCELE.  661 

seminiferous  tubes  are  found  aurrounded  by  granulation  tissue.  The 
granulations  consist  of  embryonic  tissue.  The  lesion  is  termed  henlijn 
fungvB  of  the  testicle.  Tlie  mass  gradually  diminishes  through  suppura- 
tion, and  recovery  takes  place  by  the  formation  of  a  cicatrix. 

The  surface  and  connective  tissue  of  the  epididymis,  as  well  as  the 
serous  membrane  of  the  testicle,  may  he  the  aeat  of  chronic  inflammation 
with  an  abundant  formation  of  embryonic  tissue  ;  the  latter  may  pro- 
liferate and  form  elevations  like  the  gramilations  of  fungus  of  the  testicle. 

The  granulations  of  embryonic  tissue  formed  upon  the  tunica  vaginalia 
after  gangrene  of  the  scrotum  should  not  be  confounded  with  benign 
fungus. 

Benign  fungus,  that  is,  hernia  of  the  inflamed  substance  of  the  testicle, 
in  which  the  connective  tissue  of  the  testicle  is  changed  into  granulation 
tissue,  occurs  under  various  circumstances  :  in  acute  purulent  inflamma- 
tion when  an  abscess  has  been  opened  ;  in  tuberculous  orchitis,  and  at 
times  in  syphilitic  orchitis. 

Syphilitic  chronic  orchitis  consiste  in  a  new  formation  of  fibrous  tissue 
between  the  seminiferous  tubes.  The  tubes  are  separated  from  one 
another  by  embryonic  or  fibrous  tissue,  and  are  atrophied  by  pressure.  In 
some  cases  they  are  almost  reduced  to  their  enveloping  membrane,  and 
have  in  their  interior  only  a  few  atrophied  granular  fatty  cells.  This  lesion 
may  affect  either  the  entire  testicle  or  only  a  few  lobules.  A  thickening 
of  the  tunica  albuginea  and  tunica  vaginalis  is  also  observed.  The  tunica 
vaginalis  may  present  either  vegetations  or  adhesions.  This  variety  of 
orchitis  usually  coexista  with  syphilitic  gummata,  but  may  occur  without 
them. 

Hydrocele.  Hydrocele  of  the  Tunica  Vaijinaii». — Altbougli  hydro- 
cele  of  the  tunica  vaginalis  has  been  placed  among  the  dropsies,  it  should 
be  considered  as  a  chronic  inflammation.  The  lesion  seldom  occurs  in 
general  dropsy,  and  the  fluid  in  the  tunica  vaginalis  contains  a  consider- 
able ijuantity  of  fibrin,  as  occurs  in  all  inflammatory  exudations  ;  fre- 
quently there  are  formed  fibrous  productions,  new  membranes,  and  ex- 
crescences upon  the  internal  surface  of  the  serous  mcmhranc.  This 
disease  is  characterized  by  a  serous  or  fibrinous  exudation  into  the 
tunica  vaginalis,  resulting  either  from  an  acute  or  a  chronic  inflammation 
of  the  whole  serous  membrane  or  from  a  varicocele.  The  amount  of 
fluid  varies;  it  is  generally  clear;  at  times  colored  yellow  by  a  few 
blood  corpuscles;  there  may  be  present  crystals  of  cholesterin,  swollen 
endothelial  cells,  and  enough  lymph  cells  to  give  it  a  turbid  appearance. 
In  some  cases  of  hydrocele  there  exists  a  cyst  of  the  epididymis,  which 
may  rupture  into  the  tunica  vaginalis;  in  the  latter  case,  spermatozoids 
are  then  found  in  the  fluid  of  the  hydrocele. 

The  internal  surface  of  the  tunica  vaginalis  in  recent  cases  is  smooth, 
but  the  connective  tissue  of  the  membrane  is  always  thickened.  In 
chronic  hydroceles  there  are  always  found  very  evident  signs  of  chronic 
inflammation;  there  are  superimposed,  upon  the  surface  of  the  tunica 
vaginalis,  cither  the  parietal  or  the  visceral,  layers  of  new  vascular  mem- 
branes.    These  formations  usually  consist  of  a  dense,  hard  connective

In  another  variety  of  sarcoma,  which  is  frequently  corobiiH*d  with 
eiichoiidroma,  the  tumor  contains  cvsta  varying  in  size.  These  are  ri/ttie 
mrr-omat'i,  which,  after  remaining  localised  for  a  time,  at  longtb  break 
through  the  tunica  albuginea.  and  become  genernliied,  and  malipinut  in

[  malignant  eysta  of  the  testicles  belonging  to  a  group  of  tumom  differing 
in  structure,  nature,  and  prognosis.  An  uuatonit<-a)  examinaticHti  of

Hpindlc  celled,  in  other  partit  rounti  celled,  frequently  baWng  small

(cell  nesta)  situated  in  the  cavities  of  tbe  cnlargod  tubes.  These  globules 
were  formed  of  corneous  epithelial  cells.

Malawea  has  recently  jmWisheii  Mme  otiservations  upon  this  subject, 
in  which  the  cjstic  fonnatioii^,  situated  in  the  centre  of  the  testicle,  MCre 
iieparated  from  the  parenchyma  of  the  testicle,  which  was  pushed  to  the 
periphery  in  contact  with  the  tunica  albuginea.  'Ilic  cysts  surrounded 
by  an  almost  normal  connectire  tissue,  which  contained  a  few  lympb  cells 
between  its  fibres,  varied  in  sixe  from  a  pea  to  a  hazel-nut.  Smooth 
muscular  fibres  were  found  in  this  connective  tissue.  The  internal  su^ 
face  of  the  cyst»,  cilber  smooth  or  prescntim'  villous  projections,  was  linwl 
with  cell*  varying  in  form;  jiolygoniil  mid  fl:a.  cylindrical  or  ciliated  and 
goblci-shaped.  These  several  varieties  of  cell*  were  found  united  iuio 
groups  in  the  same  cyi<tic  cavity.  The  cells  found  in  the  serous  or  mucoua 
6uid  of  the  cysts  reseml^ed  those  lining  the  internal  surface  ;  many  had 
become  spherical  and  undergone  a  fatty  degeneration.  In  no  part  could 
Malasscz  discover  a  change  of  the  normal  semiidt'crous  tabes  into  cysts; 
moreover,  the  cysts  had  no  similarity  to  the  seminiferous  tubes,  llenco 
he  concludes  that  there  is  a  new  formation  of  epitbelinm  and  of  cavities 
filled  with  mucous  epithvliuiQ,  and  be  proposes  to  call  the  neoplasm  a 
mgxoid  epithftioma.

The  testicle  at  times  ]ire«enta  very  small  gray  miliary  granulations, 
scarceW  visible  to  the  unaided  eye,  which  are  iteated  upon  the  tunica

spermatic  canaliculi.  The  miliary  granulations,  at  first  gray,  become 
caseous  at  their  centre,  and  form  lobulaled  groups,  the  centre  upon  section 
appearing  like  a  caseous  ulcer.  There  is  no  douljt  that  the  development 
of  the  granulations  commences  aroimd  the  spermatic  canaliculi.  In  ex-

Stphilitic  GcuiiATA. — Interstitial  syphilitic  oichitia  has  boon  pre- 
viously described  ;  it  remains  to  study  •{ummata  of  the  UHrticlt-s.  whivh 
arc  always  accompanied  with  an  interstitial  and  peri-orchîlis — that  is,  a 
fibrinous  thickening  of  the  tunica  albiiginea  and  rnginalis,  fn.-<iuuntly  end- 
ing in  intimate  union  of  the  two  «ertms  surfacca. 

Aceonling  to  the  di'«cription  of  Viruhow,  gnmmata  be^n  by  the  for- 
mation of  dcuHc,  librouM,  ealloua  fasciculi  from  the  tunica  albu^nea  aixl

oonicml  fasciculi,  or  large  masses  having  a  spherical  or  lobulated  sha]>e. 
nils  fibnut  tiwue  taking  the  place  of  the  aeminiferoos  tubules,  which  are 
completely  atrophied  at  the  eurfaco,  becomes  lutpr  the  wat  of  yellow 
gummatous  tumors,  located  either  in  tbc  tJiickciR-d  ttinica  nlbu^^nea  or 
in  the  fibrous  tissue  developed  in  the  testicle.  These  yellow  gummatous 
maasca  are  nothing  more  than  the  caacous  degencraUons  of  the  pre-fonncd 
fibrona  tissue. 

Sypliililic  gnmmata  are  very  easily  recognised  and  differentiate*!  from 
etlier  legions;  tliey  have  been  described  by  Curling  as  chronic  orchitis. 
The  hardnoH  of  gunimaia,  even  wlten  they  have  become  cai^^outi,  the 
great  fibrous  induration  of  the  substance  of  the  testicle  where  the  semi- 
nifemuB  tubes  are  atrophied  and  separated  by  fibrous  tissue,  disUnctly 
discriroÏDatea  this  lesion  from  the  tubercles  in  which  the  cxmious  foci  are 
soft,  suppurate,  and  have  a  tendency  to  open  externally  by  fistular  tracta. 
Again,  the  induration  of  the  epididymis  i^  less  frequent  than  tlint  of  the 
testicle;  also  gnnimnta  of  the  epididymis  arc  more  rare.  The  large 
tubercles  of  the  cjiididyrai*  and  vas  dcft;ron«,  which  arerery  characteria- 
tic,  arc  more  common  tiian  taberelei  of  the  testicles.  Sypliilis  of  the 
testicle,  in  consequence  of  the  complete  atrophy  of  the  seminiferoua 
tubes  by  the  precsitre  of  the  connective  tissue,  entirely  arrests  the  frnio* 
tion  of  tlic  gland,  'lliere  i»  no  positive  evidence  of  suppuration  or  an 
extendi  o)>t'tiing  of  gummata  of  tlte  testicle.  This  eatablishes  an  essen* 
tial  dilferetice  between  tliese  formations  and  tubercles. 

Lyhphadbxojia. — We  know  of  but  one  case  of  tymphadcnoma  of  the 
testicle.  It  was  described  by  Mnlussex.  The  tumor  of  tlio  testicle  was 
formed  of  a  typical  rctictdatcà  tissue,  the  meshes  of  which  were  filled  witli 
lymph  cells.

part  of  the  testicle,  or  from  the  rete  tetitis,  or  from  the  oorpu.4  llijilim»-

the  place  of  its  development,  under  the  tunica  albuginea,  a  gray  and 
opu()uc.  or  pink  layer,  which  consista  of  the  seminiferous  tubes  pushe-l

Kiirro\inded  by  new  very  vascular  connective  tissue,  and  they  cannot  be

I  nature;  the  epiilidymi»,  the  cord,  the  pelvic  antl  reiro-i>critoneal  lyinpli 
glands  arc  aUo  involved.  From  our  inve^^tigaticns  the  )>«niini(croiH 
tubes  do  not  seem  to  be  the  jioinl  of  origin  of  carcinoinA  ;  yet  Birch- 
Ilirschfeld  has  isolated  seminiferous  tubes,  which  presented  ncw-foniwi) 
protuberances,  increasing  rapidly  a^  they  penelrated  into  tlie  ntorbid 
mass.  According  to  lliis  writer,  curcinoina  of  tlie  testicle  has  its  ori^n 
in  a  new  fonnution  of  epithcloid  ulcnicnU  in  the  interior  of  the  semi- 
niferous tubes.  We  have  not  been  able  to  verify  tlii»  mwlc  of  develop 
ntcnl,  and  do  not  Leliere  that  cairinoma  is  developed  in  tlie  tubi;»,  but  id 
tJic  connective  ti«»ue,  by  the  swelling  of  the  connective  tisiiue  cell»,  and 
tlic  new  formation  of  large  cell*,  which  occupy  the  connective  tissue 
spaces  between  the  fasciculi  of  the  tihres  and  the  lym[))iatic  cavities. 

The  most  freijuent  variety  of  i^arcinoma  of  llie  testicle  is  encephiib-id; 
the  .surface,  upon  section,  is  while,  doughy,  and,  upon  pressure,  oxinlea 
a  larjjo  ipianiity  of  milky  juice.  To  the  uiiiiided  eye.  it  is  impossible  to 
confound  this  tumor  with  a  sarcoma,  which  contains  juice  only  when  it  is 
undergoing  cadavcrie  decomposition.  Sometimes  an  cncephaloid  pr»- 
scnts  a  great  development  of  capillary  vessels,  and  is  then  terrace 
bii:matoi<(-earcinum&  ;  it  is  then  very  friable,  and  the  conucctivc 
small  in  amount.  Hi^ologicnl  exnniination  of  this  variety  of  carcinon 
of  tlie  testicle  presents  very  distinctly  all  the  cliaraeteristics  of  sueh 
formations. 

ijcirrhus  of  tbe  testicle  is  extremely  rare  ;  several  writers  deny  thai  it 
ever  occurs.    îlepveu  has  studied  and  published  one  case  of  this  variety. 
Melanotic  carcinoma  (or  melanotic  sarcoma)  has  been  noticed  as  a 
sccondarv  tumor  of  the  testicle. 


Many  case-s  of  tumors  published  as  cancer  of  the  testicles,  with  iosnS- 
cicnt  Instolojiical  details  or  oven  without  microscopic  examination,

with  cystic  sarcoma,  and  admit  that  a  sarcoma  may  be  tranaformeil  into 
a  carcinoma.  These  are  very  interesting  points,  and  as  yet  remain 
unexplained. 

Tlie  testicle  is  sometimes  the  eeat  of  dermoid  cysts  and  cysts  of  fœtal 
origin. 

iîoth  striated  and  non-striated  muscular  fibres  have  been  found  in 
connection  with  sarcoma  of  the  tcâticle. 

There  are  reported  some  very  rare  cases  of  hydatid  cysts  with  echiuo- 
cocci  developed  in  the  epididymis  and  tunica  vaginalis.

tion.     But  an  opening  m&y  take  place  into  the  bladclor,  the  Beminal  vesi- 
cles, the  surrounding  connective  tissue,  or  into  the  peritoneal  cavity. 

Tumors.  Hypertrophy. — The  increase  in  size  of  the  prostate  is  s 
physiological  fact  occurring  in  advanced  age.  The  venous  vessels  of 
the  gland  and  perineum  are  dilated;  the  fibro-muscular  tissue  becomes 
thicker  and  denser  ;  the  glandular  vesicles  are  hypertrophiod  and  multi- 
plied  ;  and  the  prostate  is  enlarged  cither  uniformly  as  a  whole  or  in 
some  of  its  parts — the  right,  left,  or  middle  lobe. 

Prostatic  concretions  or  calculi  are  also  fretjucntly  met  with  in  old 
persons.  They  are  formed  in  the  interior  of  the  glandular  acini  or 
ducts.  Their  size  varies  from  .004  mm.  to  .005  mm.  up  to  a  half 
millimetre  or  one  millimetre  in  diameter.  The  smallest  are  round  or 
oval,  refracting,  and  colorless  ;  they  consist  of  a  hard  colloid  substance 
difficult  t«  crush  ;  with  tincture  of  iodine  and  sidphuric  acid  they  offer 
the  same  reaction  as  do  parts  affected  with  amyloid  degeneration,  and 
have  been  described  by  Virchow  as  due  to  amyloid  degeneration.  The 
larger  calculi  arc  more  resisting,  yellow,  yellowiah-brown,  or  darkisli- 
brown  in  color,  and  present  concentric  layers  ;  escalate  or  phosphate 
of  lime  may  be  deposited  upon  them  in  laminœ,  when  they  become  very 
large.  The  glandular  acini  and  ducts  dilated  by  the  calculi  are  filled 
with  a  mucous  fluid,  so  that  when  the  prostate  is  the  seat  of  numerous 
concretions,  which  is  often  the  case,  the  gland  is  transformed  into  a  series 
of  cavities  which  give  it  the  appearance  of  cavernous  tissue.  These 
cavities  are  lined  with  a  cylindrical  and  polygonal  epithelium,  several 
layers  thick.  The  calculi  remain  in  position  and  do  not  produce  any 
symptoms,  or  they  are  passed  through  the  dilated  excretory  ducts,  and 
give  rise  to  inflammatory  troubles  either  in  the  prostatic  ducts  or  in  the 
urethra. 

General  or  partial  hypertrophies  should  be  placed  among  myoraata  of 
the  prostate,  due  to  the  new  formation  of  a  very  dense,  grayish-white  or 
pinkish  tissue,  consisting  of  smooth  muscular  fibres  and  newly  formed 
connective  tissue.  The  glands  of  the  prostate  also  increase  in  size  at  the 
same  time  that  the  cellulo-muscular  tissue  is  developed,  and  there  is  seen 
a  new  formation  of  glandular  acini.  Such  a  growth  might  be  considered 
as  a  mixed  tumor  or  adeno-myotna. 

A  ijeneral  hypertrophy  of  the  prostate  due  to  the  formation  of  new 
fib ro- muscular  tissue,  is  not  usually  uniform,  but  commonly  forma  nodules 
or  elevations,  which  frequently  project  into  the  urethral  canal  and  offer 
an  obstacle  to  micturition  and  cathetcrism.  ïlie  enlargement  is  not  al- 
ways symmetrical,  and  there  may  result  a  lateral  displacement  of  the 
urethra  in  the  prostatic  portion.  The  consequence  of  hypertrophy  of  the 
prostate  is  an  increase  in  the  calibre  of  the  prostatic  region  of  the  ure- 
thra, but  it  occasions  at  times  great  difficulty  in  the  passing  of  instru- 
ments into  the  bladder,  because  of  the  development  of  nodules  projecting 
into  the  urethra  and  often  uplifting  the  neck  of  the  bladder. 

Partiid  hypertrophy  is  characterized  by  the  nodules  which  form  upon 
the  surface  of  the  prostate,  very  similar  in  structure  to  the  preceding, 
and  generally  developed  around  hypertrophied  glandular  acini.

Wlien  the  GranliHti  follicle  has  reached  a  centimetre  in  diameter,  and 
projects  from  the  surface  of  the  oviiry.it  ruptures  and  empties  its  contents 
into  the  Fallopian  tube  during  thv  luhido-ovurian  con^stion  which  aceom-

Uraafian  follicle  niplure:*  upon  the  «urfacc  of  the  ovary,  for  nnnicrotu

Again,  it  has  been  proved  that  fecundation  and  gestation  have  occurred 
in  some  cases  after  (hf  menopause  and  witboat  «ny  return  of  menstms- 
tion.  Itut  notvritfastandin^  these  facts,  which  are  exceptions,  it  is  doteiv 
mined  that,  as  a  ^neral  rule,  meuslriiatio»  corresponds  with  the  pasaing 
of  an  ovule  by  tlie  Kallopian  tube  into  the  uterus. 

Tlie  ovisacs,  or  primordial  follicle»  containiii<i  the  ovule,  come  from  dis- 
tinct i^landular  tubes  which  exisit  in  the  orary  of  the  embryo.  Aeconl- 
ing  to  i*tlu;;er,  they  are  formed  by  an  envelope  lined  with  n  layer  of 
finmll  epithelial  cellii,  which  represents  the  granular  merohraue  of  the 
Ornafian  fnUicle,  and  inclose  at  their  centre  a  aerie»  of  nidimenlary 
ovules.  By  the  growth  of  these  omles  and  their  surrouniling  connective 
tissue,  the  tubes  are  partitioned  by  the  connective  tiHsiie,  and  divided 
into  separate  very  small  se^mentn.  Kacii  se;;ment  now  contains  an  ovule 
surrounded  by  a  xonv  of  ejnttielinl  colls,  and  constitutes  an  ovisac. 

When  the  tiraalian  follicle  has  emptied  its  contents  into  the  oviduct, 
it  undergoes  a  scries  of  change»,  being  transfurmed  into  what  is  known 
ns  the  rorfut  fulram.  Tliesc  bodies  diffor  aeconling  to  whether  the

This  cavity  is  lined  by  a  wrinkled  yellowish  or  whitish,  very  vascular

arci  seen,  in  it^  indnrati-il  |iarencliytna,  several  follicloa  which  are  lîllvd

the  eoajçulfttcd  blood  which  dLitends  th^'m  iti  darlc  brown  or  black,  and 
nnderjtoe.i  the  usual  chan;res.  Tiiese  [lathological  [iroducia  are  easily 
distinguished  from  corpora  lutca  ;  in  the  normal  state  there  is  never  more 
than  a  «ingle  follicle  which  contains  blond,  and  it  is  that  of  the  last  men. 
etruation,  the  cicatrix  is  also  easily  scon  which  corresponds  to  it  H|»on  the 
surface  of  the  ovary.  Patholo^cal  h«morrha<;e,  on  the  contrarv,  occurs 
in  two  or  three  folhcles  of  one  ovary  or  tn  both  ovaries,  us  well  >n  the 
deep  OS  in  the  supi-rliclal  follicles.  Follicular  hemorrliagcs  sometimes 
occur  with  chronic  peri-ovarian  ndhc^five  peritonilij,  or  irith  [lathologicBl 
adhesions  of  the  Fiillopîan  tube  which  prevent  the  normal  nipturing  of 
the  folliclcx.  In  !4uch  cases  there  is  at  the  same  lime  n  caltoii»  thickening 
of  the  ovary  and  retrograde  chan^^a  of  the  Irraatian  follicles,  which  are 
soinetiiucs  Ailed  with  a  mucous  tissue,  or  have  tiecome  droiwucal.  When 
the  ovary  in  free  frvim  adhesions  and  when  hemorrhage  occurs  in  a  «nper- 
licinl  follicle,  there  may  result  a  rupture  of  ita  wall  and  a  more  or  leas 
abundant  hemorrhftfjo  into  the  pôritoneal  canty. 

Inflammation  op  thb  Ovart,  Otabitis. — During  gestation,  the 
phoDomcna  which  occur  in  the  ovary  are  iiiHammatory,  and  constitute, 
what  may  be  tiirmed,  a  physiological  intlummiitioti.  The  parenchyma  is 
tumefivd,  and  tlie  circnlation  more  active,  owing  to  which  the  cor]>ns 
lutemn  of  gestation  is  of  unusual  site;  the  cells  of  the  connective  tisane 
are  lar^e  and  cloudy  ;  there  is  also  a  greater  number  of  migrating  lymjih 
celU;  the  smooth  muscular  fibres  are  more  swollen  ana  longer,  and 
comparable  to  the  same  elements  in  the  wall  of  llie  uterus  during  ges- 
tation. 

From  these  nutritive  changes  the  organ  is  disposed  to  a  more  or  less 
intense  pathological  intiammaiion  after  delivery  or  after  an  abortion. 
ITiua  it  IS  almost  exclusively  in  women  recently  delivered,  that  acnte  in- 
flammations arc  met  witli,  or  they  may  occur  in  connection  with  metritis 
and  peri'Uvnrinn  peritonitis.  The  lesions  vary  in  iutcn^fitv*  In  a  slight 
fonii,  the  ovary  is  saturated  with  flnid,  nuil  then;  is  an  mfiUnition  into 
il8  c<uin(-otivc  ti.'<#ue  of  uumenxiM  lymph  cell».  The  fully  developed 
Uraatiau  follicle.^  have  in  their  interior  ii  turbid  tluid,  souiciimes  colored 
by  blood,  and  containing  a  ^rent  tiumher  of  epithelial  and  lymph  cellit,

the  same  time  that  tliere  is  fourni  a  very  inleuse  congesQen  and  new 
Bbrinou3  membranes  ujmn  the  surface  of  tiic  ovary,  there  is  a  more

carcinoma  is  not  very  recent,  and  there  are  tlion  found  upon  the  cnpside

in  n  limited  part  or  ihrou^tlnnu  ii»  entire  extent,  very  soon  participates 
in  tha  Jc^^cne ration  of  the  ovary.  We  have  several  times  seen  cnormoua 
tumors  with  cancerous  perit«nitis  in  youn;r  persons.  Tho  structure  of 
enccpbaloid  carcinoma  of  the  orary  docs  not  much  differ  from  that  of 
typical  cnccphaloid  :  besides  tbe  connective-tissue  fibres,  the  trabeculie

Htroma,  or  they  nm  placed  |>cr|4'ndiciilar  to  tha  wall  of  the  cavities.  Tho 
vetMels  are  Komelimes  of  lar^e  fisc,  constituting  a  hiematoid  cancer.  In 
earvinoma,  as  in  other  tumon  of  the  ovary,  cysts  are  fountl,  which  liave 
formed  witli  the  tumor,  or  have  preceded  its  derelonraent.  Usually, 
vegetations  formed  of  carcinomatous  tiitflue   project  into  the  cavity  of 

thne  cjrsu. 

Primary  carcinoma  may  be  coUoid  in  character;  this  variety,  however, 
is  not  »o  fre<|uent  as  scirrhus. 

Secondary  tumors  of  the  ovary  offer  the  «ame  «truclnre  as  the  pri- 
mary formations.  For  example,  eylirxlrical  or  jinveoient-oell  epithelioma 
of  the  ovary,  oconre  secondary  to  tumor»  of  the  same  nature  developed 
in  llie  uterus. 

CyhiidrÎLal-celled  epithelioma  may,  «ceoiviin;;  to  the  investigations  of 
Rindtleisch  and  Kleb«,  be  developed  primarily  in  the  ovary.  In  a  case 
reported  by  the  latter,  a  reproduction  in  the  cutaneous  wound  followed 
tlie  e:(drpation  of  tlie  tumor.  An  examination  of  the  cutaneous  tumor 
sboweil  it  to  consist  of  gland-like  tubes. 

OVAHIAS  CïSTS, — Of  ail  the  new  formations  and  diseases  of  the  ova. 
rics,  cysts  arc  the  most  common,  and  the  most  important  iu  view  of  their 
development  and  their  results.  The  ovary  and  kidney  arc  organs  in  which 
these  formations  have  the  greatest  tendency  to  be  developed.  It  has 
already  been  seen  that  cysts  may  form  in  tumors  of  the  ovary,  aud  it 
now  remains  to  describe  cysts  proper,  which  vary  much  in  their  develop- 
ment and  nature. 

I.  Ifr-'i'iiti  iif  the  Ormfian  FoUirlrt. — Itolcitannky  ha»  shown  that  the 
Graaliau  follicles  may  be  »o  distended  by  a  serous  anil  limpid  tluid  a»  to 
form  small  cystic  cavities,  the  sixe  of  a  small  bean  or  hazel-nut.  In  an 
ovarian  tumor  coro)>osed  of  cysts  of  this  site,  this  author  has  shown  that 
each  one  stiU  contained  an  ovule.  The  cyst»  from  distension  of  the  folU* 
c1g«  are  generally  small,  and  the  tumor  id  seldom  larger  than  the  6ât.

There  ia  no  evidence  that  a  single  primary  cyst  divides,  forming  two  or

t  he  accepted.  Neither  is  tliere  found  any  trace  of  ovisacs  or 
Ornnfian  follicleâ.  tho  ovary  bom;;  eamplcicly  tfnnsformed  into  cvfts 
analogous  to  those  vro  have  described.  The  entire  absence  of  ovariao 
follicles  sertcs  as  an  argument  for  writers  who,  like  Virchow,  Waldoyer, 
etc.,  explain  the  genesis  uf  multilocular  cyst*  by  changes  of  the  oraiian 
tuben,  which  are  described  by  l'Au^^cr  in  fuutal  life.  There  «re  muK 
points  of  analogy  of  structure,  and  the  comjiarison  is  ingeniotui;  hut 
there  is  no  jirool  that  the  targe  or  tiie  more  recent  cysts  have  their  origin 
from  the  ovariun  tubes  of  fœtal  life. 

We  have  described  in  part  first  the  structure  of  vegetations  upon  th« 
wall  of  cysts.  We  adniitted  die  possibility  of  the  development  of  second- 
ary cysts  according  to  the  method  indicated  by  Wilson  b'ox,thatiB,  by  the 
union  of  villi,  which  in  uniting  fonn  closed  cavities.  The  more  recent 
investi^TJàons  bv  MalaS'Sez  weaken  this  view  of  the  mode  of  formation.  He 
hn.s  seen  secondary  cysts  form  in  the  villi,  appearing  at  first  as  a  small 
collection  of  cells,  the  most  central  of  which  become  mucous,  and  aro 
destroyed  in  forming  a  cavity,  around  which  the  paricud  cells  become 
epithelioid.  Tliis  mode  of  fonnutîon  is  compamblc  to  that  which  has 
been  described  hy  Focrster.  From  a  later  investigation  Mahu»C7.  was 
led  to  believe  that  there  oecurj  in  these  tumors  a  new  formation,  a  tntv 
epithelial  heterotopia,  a  peculiar  epithelioma,  and  from  the  fact  that  the 
epithelium  has  the  property  of  forming  a  mucous  secretion,  he  iwmes  it, 
as  in  the  corresponding  cystic  disease  of  the  tesdcle,  a  mt/xoid  ejfi- 
thelioina. 

When  the  cysts  are  old  or  during  their  peiiod  of  growth,  they  may,  in 
consequence  of  peritonitis,  he  intimately  united  to  the  neighboring  [larw, 
rendering  the  oporatioD  of  ovariotomy  very  difficult  and  dangerous.

CHAPTER   VI. 

FALLOPIAN  TUBES  AND  UTERUS. 

Sect.  I.— Nonoal  Histolofrr. 

Oviducts  or  Fallopian  Tubes. — These  are  the  temporary  ducts  of 
the  ovaries,  sen'inj;  for  the  pas6a<;c  of  the  ovule.  The  fimbriated  ex- 
tremity is  applied  to  the  surlace  of  the  ovary  at  the  time  of  the  rupture 
of  the  Graafian  follieIe,and  it  receives  the  ovule  wliich  passes  along  the 
tube  to  the  uterus.  The  ducts  consist  of  a  peritonei;!  covering, which  sur- 
rounds them,  of  a  layer  of  fibrous  and  muscular  tis.^ue  forming  their 
Tvall,  and  a  mucous  membrane.  They  present  for  consideration  a  fim- 
briated extremity  which  is  attached  to  the  ovary  by  a  short  ligamentous 
cord,  an  inferior  and  narrow  part  traversed  by  a  canal  which  passes 
through  the  muscular  tissue  of  the  uterus  at  each  lateral  comua,  and  opens 
into  the  cavity  of  the  uterus  by  a  very  small  orifice  scarcely  large 
enough  to  receive  a  fine  bristle, 

The  lumen  of  the  tube  in  its  free  portion  is  large,  and  its  mucous 
membrane  is  longitudinally  folded  like  that  of  the  vas  deferens.  From 
itâ  free  extremity  to  its  uterine  orifice,  the  mucous  membrane  of  the  tube 
is  lined  with  a  ciliat«d  cylindrical  epithelium.  The  movements  of  the 
cilia  cause  a  current  in  a  direction  from  the  free  extremity  towards  the 
uterus,  assisting  the  progress  of  the  ovule,  but  not  that  of  the  sperraato- 
zoids.     There  are  no  glands  in  the  mucous  membrane  of  the  oviducts. 

Uterus. — The  uterus  presents  for  consideration  the  body  or  superior 
part,  and  the  nock  opening  into  the  vagina.  It  has  a  cavity  passing 
through  it  from  the  fundus  to  the  os,  which  is  narrowed  at  the  union  of  the 
body  with  the  cervix.  The  uterus  is  covered  by  a  layer  of  connective 
tissue  and  cells  belonging  to  the  peritoneum  :  it  possesses  a  very  thick 
wall  consisting  of  smooth  muscular  fibres  and  connective  tissue.  The 
muscular  fibres  are  difficult  to  separate.  The  superficial  layer  is  com- 
posed of  fibres  running  longitudinally  and  transversely  ;  the  first  form 
a  thin  layer  extending  over  the  fundus  and  the  anterior  and  sujierior 
surface  of  the  uterus  ;  the  second  a  thick  layer  wiiich  extends  partly 
into  the  round  ligament,  the  broad  ligament,  and  tlie  oviduct.  The 
middle  layer,  which  is  the  thickest,  consisU  of  longitudinal,  transverse, 
and  oblique  fasciculi.  The  most  internal,  like  the  external,  is  very  thin, 
having  intersecting  fasciculi  which  form  circles  at  the  orifices  of  the  ovi- 
ducts. The  transverse  fibres  of  the  cervix  constitute  a  true  sphincter. 
In  the  cervix  there  are  also  found  some  very  superficial  fibres  in  the  folds 
of  the  arbor  vitte.  The  muscular  fibres  of  the  uterus  and  Fallopian  tubes 
are  short  except  during  pregnancy  :  they  are  separated  hy  a  large  quantity 
of  dense  connective  tissue  couuining  oval  cells.

The  gland»  of  the  muoou«  membrane  of  the  civvily  are  sim)>1o  or  bifur-

lined  with  a  cylindrical  epiûielium,  and  open  upon  the  mucous  membrane, 
either  singly  «r  two  or  three  together. 

The  mitcous  membrane  of  the  cervix  of  the  uterus,  inntetid  of  being 
smootli  as  in  the  horly,  presents  folds  which  unite  to  form  the  arbor  vit». 
These  folds,  and  the  entire  mucous  membrane  of  the  cervix,  are  covered 
vith  villi.  Bctivecn  the  folds  are  seen  crypts,  which,  aa  well  as  the 
cavity  of  the  ccrvjs,  contain  a  viscid  and  transparent  mucus.  Upon  the 
surface  «f  the  folds  are  found  utricular  déprécions  itituaCcd  between  the 
villi.  In  the  bolt<im  of  the  crvptif  are  the  njienin^s  of  aeinou8  glands

cyliiidrifttl  cell*,  and  they  are  filled  willi  a  viscid  mucus. 

The  itujierficini  epithelium  of  the  cavity  of  the  uleruit  is  a  single  layer 
of  cylindrical  cell».  Some  writers  describe  them  as  ciliated  ;  other»  deny 
the  existence  of  cilia.  Ninety  has  seen  ^Met-shaped  epilbclium  u]>cia

the  mucotis  membrane  coiwiate  of  co&iwctive  tissue  foniiiugiiitpillie,«hich 
lie  bonontli  a  linninatcd  pavement  epitheliinn. 

A  similar  arrant^emetit  of  the  iimci^u.'*  tnemhraiie  ami  epithelium  exists 
over  the  entire  surface  of  the  vai^ina.  The  hard  excrescences  found 
upon  the  surface  of  the  vagina  are  nothinjt  more  than  prominent  papillary 
formations  covered  with  lauiinatod  epithelium. 

The  arterial  vesaels  of  the  uterus  run  in  the  muscular  substance  and 
form  capillary  networks,  which  ramitjr  in  the  mucous  membrane  and 
muscular  layers.  The  veins  arc  without  valves,  very  large,  have  thin 
nails,  and  follow  the  same  course  as  the  arteries.  The  lymphatics  arc 
Tcry  numerous  ;  they  probably  originate  in  tho  mucous  membrane,  and 
form  upon  the  surface  of  the  nterus  beneath  the  peritoneum  a  clo4C  net- 
work which  conimunicateK  with  the  pelvic  and  lumbar  glands. 

The  ccUulo-vaMiular  tissue  of  tliv  broad  ligimienU  contains  smooth 
murieular  fibres  (Rouget). 

During  menstruation,  tho  very  notable  increase  in  the  sixe  of  the  uterus 
U  due  to  the  coniiiderable  afflnx  of  bloo«l  into  its  ti^ue,  and  to  a  awellin^ 
of  the  mucous  membrane.  Thii*  membrane  during  menstruation  eiperi- 
mcee  great  hypertrophy;  it  becomes  softer,  anil  the  glaniU  are  readily 
isolated,  measuring  fri^ini  two  t<>  six  millimetres  long  and  .OT'I  mm.  to  .090 
mm.  wide  ;  the  connective  tissue  of  the  mucous  membrane  is  swollen  and 
contains  numcrtiiu  tymph  cells.  Hie  vessels  arc  dilated  and  very  abun- 
dant. At  the  same  time  that  the  menstrual  blood  is  diechargetl.  the 
epithelium  of  the  cavity  of  thv  uUths  i«  almost  entirely  cast  off.  Klimi- 
nation  of  the  glaiuU  and  of  slireds  of  exfoliated  mucous  membrane  during 
nenstruauoii  arc  pat)iologieal  lesions. 

We  ha^e  fre.juently  had  an  op[>ftrt«nity  of  examining  the  products 
discharged  during  menstruation,  coinciding  with  xymptoms  known  as 
jmfudv-membraHouf  d^tmeuorrhtta.  They  vary,  at  times  consisting 
simply  of  coagulated  fibrinous  clots,  which  are  with  dilficulty  passed 
through  the  onfice  of  tiie  os  uteri  when  it  is  very  small,  as  is  frctjucnlly 
tlie  case  in  females  who  have  never  borne  children.  Microscopie  exami- 
nation  shows  the  fibrin  in  a  fibrillatcd  slate,  inclosing  in  its  reticulum 
numerous  lymph  and  epithelial  cells. 

In  other  eases  there  are  found  irregular  slirods  eontiuning  capillary 
Tessels  with  embryonic  walls.  In  the  midst  of  connective  tissue  infiltrated 
witli  Irmpli  cell».  There  are  also  frequently  seen  fnignient«  of  uterine 
glamlH,  or  entire  glands.  This  is  a  genuine  discharge  of  exfoliated  mu> 
co»s  membrane.  The  mucous  iiK-mbrane  may  l>e  expelled  entire;  tltis, 
however,  is  not  a  fretiuent  occurrence. 

In  a  thini  and  larger  series  of  cases  the  products  cnnaiat  of  the  débris 
of  tiie  decidua,  which  are  recognized  by  the  villi  of  the  chorion.  The 
surface  of  the  discharged  membrane  presents  villi,  which  are  easily 
demonstrated  bv  placing  it  in  water  ;  the  villi  are  formed  of  branching 
cylinders  containing  vessels  in  their  interior,  and  covered  upon  the  surface 
with  epithelium.  There  is  atiio  found,  if  tho  membrane  is  discharged 
entire,  a  smooth  portion  or  a  cavity  containing  the  embryo.     Wo  arc  of

consists  of  a  soft,  pulpy  tissue,  in  which,  amon^  embryonic  connec-

The  latter,  which  are  connective  tissue  C'lrpusclea.  arc  swollen,  flat  or

not  yet  entirely  known.  Vet  there  is  one  frequently  found  at  the  fim-

the  wrrix  uithiu  view  is  nlwnvs  attci-cd  to  a  varving  extent.  Tliiia  in 
cntarrh  of  the  cervix  or  caviiy,  when  the  catarrlial  fluid  flows  in  nhuii- 
danoe  froiu  the  uterine  oritiee,  it  remains  in  contitct  with  th«  lips  of  t)iu 
oe  nleri,  especiallv  the  posterior,  and  there  results  at  finit  a  superficial 
erosion,  afterwards  a  true  ulcération,  which  rlcstrovs  tlio  epithelial  corer- 
in|*,  particularly  in  the  middle  of  the  posterior  lip.  In  elironie  states, 
there  is  ut  tliid  jioinl  a  ;;ri>wth  of  the  papillic  of  tlie  mucous  ineinlimiie,  in 
the  fonn  of  siunll  gmuulatioiis  composol  of  enihr,voi)ic  vomtvetiv^-  tivue

tisBne  becoming  fihrouit,  fiiuill^r  becoiniujç  buried  under  the  epitheliuni. 
In  tboae  etaet  favorable  for  the  Alu<ly  of  their  development,  it  is  seen 
that  theiie  granulalionii  have  their  ori^ii  in  a  proltfemtire  inllammation 
of  the  papillae  which  normally  exist  under  the  laminated  epithelium  of 
this  portion  of  tlic  mucous  membrane  of  the  cen'ix, 

'riie  mucous  membrane  of  ttie  os  uteri  mar  be  the  seat  of  numeroua 
cru]>tions,  Bitch  as  vesicles  of  herpes  similar  to  thow  occurrin-;  upon  tlio 
TuKa  and  prepuce,  bullx  of  pemphigus,  eruptions  in  conm-ctii>n  with 
«niptive  fevers,  simple  or  indnrateil  clmncrc,  mucous  patches,  vegetations 
deteloping  upon  the  stirfncfi  of  mucous  piitchf>i,  etc.  In  iiei:<indiiry  .^yphilia 
tliere  are  almost  always  found  a  redness  of  the  cervix  and  a  uterine 
catarrh,  tiic  latter  ])ani«idarly  when  there  are  several  mueo^s  patches 
upon  tlie  surface  of  the  cervix  fullowing  erosions. 

In  chronic  eatarrii  of  the  cervix,  the  mucous  membrane  of  the  intra- 
raginal  portion  frei(uent!y  contains  eg-;?  of  Naboth.  The  catarrh  of  llio 
nterus  {[uile  often  extends,  as  has  lieen  prt'%iously  mentioned,  to  the 
mucous  membrane  of  the  Fallopian  tubes,  and,  hy  extension  alonf;  the 
latter,  there  may  occur  a  subacute  pclvic-peritonitis. 

All  onfreqncnt  result  of  inflammation  of  the  mucoiu  membrane  consists 
in  ft  narrowin;;  of  the  internal  04  and  cervix.  The  purifonn  or  scro- 
mucniw  catarrhal  fluid  tlicn  accumulates  in  the  cavity  of  the  utenix  and 
distends  it.  The  mucous  membrane  atrophies  from  pr«>ssure,  and  ihe 
miiMulnr  coat  is  generally  tJiinneil.  We  have  seen  this  lesion  very  often 
in  ohl  women,  and  it  is  probably  the  result  of  a  senile  atresia  of  the 
corvico-ut4:rine  orifice. 

When  tiie  inflammation  of  tlie  mucoun  membmne  is  very  violent,  tiiere 
is  an  infiltration  of  ib<  mucous  membrane  with  lyntpb  cells  and  fibriu,  in 
such  abun<L-inee  that  su[ierficial  monificadon  or  ulceration  may  be  the 
result  :  ibis  is  oliaerved  in  tvphoid  fever  and  low  types  of  eruptive 
fevers,  but  not  in  every  case,  it  being  an  unfre-iuent  complication. 

These  inSammalory  lesiona  involve  only  the  mucous  membrane,  aivd 
do  not  extend  to  iho  fibio-museular  tissue.  Yet  it  is  possible,  from  the 
severity  of  a  chronic  catarrh  of  the  cervix,  that  it  may,  by  the  congestion 
of  Ibc  deeper  parts  of  the  mtieoos  membrane,  by  the  fonnation  of  fibro- 
■nacwM  polypi,  cause  also  a  more  intense  nutritive  activity  of  that  [utri

From  what  viv  know  of  tlie  loc)ilir.atioti  of  these  tumors  in  iceneral,  they 
appear  to  have  their  ori>;iti  otdy  in  niuemia  uiembranei*  xhich  possesi  a

laminated  pavement  oclU,  while  there  is  a  layer  of  cylindrical  cells  apou

At  avit»]isies  it  is  very  difficult,  and  fretpiently  impotiaible,  with  tlie 
unaided  eye,  to  make  an  anatomical  diagnosis  between  the  varieties  of 
epilheliouu  or  between  them  and  carcinoma.  V^Undrieal  felled  ffiilif- 
Itoma  is  a  tumor  generally  verv  soft  and  infiltrated  with  juice,  reaei~ 
bling  a  very  soft  encephaloid  ;  it  also  has  lacunar  cat-itiea  filled  with 
milky  juice,  which  are  visible  to  the  unaided  eye.  Tbe  alveitar  spaeea 
contain  cylindrical  cells,  and  their  walls  have  numeixiua  eanllary  loopa 
projecting  into  the  spaces  covered  with  cylindrical  cells.  In  the  thr« 
cases  which  wo  have  seen,  and  in  which  histological  examinations  were 
made,  there  was  an  extension  of  the  tumor  to  the  neiglihoring  parted 
to  the  glands,  to  the  bladder  utid  rectum  in  one  cose,  to  the  sciatic  and 
crural  nerve»  in  niiutbi-r.  In  one  iiU  the  tis«ue  of  the  nti-rus  was  invnilcd. 
aa  were  also  the  lymphatir  vi-ssels  upon  the  ]H>riluiiCHl  surface.  There

J'avtiiiietU'CelUd  eintluUoma,  which  in  about  onedialf  the  cases  po»- 
seiases  pearly  botlies,  presents  characters  by  which  it  may  sometimes  be 
recoginzed  with  the  unaided  eye  at  autopsies,  I'ortions  of  the  tumor  are 
alightly  vascular,  having  the  opa<4ue,  waxv,  and  apparently  firm  appear- 
ance, which  is  in  contrast  with  its  friabifity.  L'fion  sec^on  its  surface 
is  dry  :  and  by  pressure  small  grumous,  vermiform,  opaque,  white  jdug»,

Ulceration  with  its  several  conserjnences,  eepccially  gangrene  of  tlie 
altered  part,  is  the  eame  in  epithuliomata  »a  in  oarcinoinata.  In  pav«- 
tnent^relied  epithelioma,  the  diseased  part  of  the  neck  may  entirely  dis- 
appear. Tlie  noighborinj'  organs  arc  neither  so  frei|uently  nor  *o  ex-

both  upon  the  vaginal  surface  of  the  ulceration  and  in  tlio  pelvic  and 
lumbar  elands. 

The  difTerent  varieties  of  carcinoma  and  epîtlielïoroa  are  usually  de< 
velfl]icd  at  the  time  of  the  roenopaune  or  a  few  years  later  ;  yet  they  hare 
been  observed  in  youngwomen  from  twenty  to  thirty  yeareofage.  The 
tumor  of  the  cenix  does  not  prevent  fecundation,  parturition. or  ilclirory. 
After  delivery  the  lesion  of  the  uterus  progresses  with  great  rapidity. 

B.   LKStOSS  OF  THE  FlBUU-ML'gCULAR  WaI.L. 

The  fibronrnsciilar  wall  of  the  uterus  generally  escapes  involvement 
in  catarrhal  intinmmation,  and  it  is  markedly  affected  only  in  puerperal 
inSammaiion.  The  veinn  are  attacked  with  inflammation,  and  abscesses 
may  be  developed  in  their  wall. 

Lesions  of  the  uterine  wall  mostlT  consist  in  a  new  formation  of 
smoo^  muscular  and  fibrous  tissue,  wbicb  occasions  cither  a  gcucnil  or 
a  local  hypertrophy  of  the  wall.  A  local  hvpertrophy  when  sharply 
limited  may  be  regarded  as  a  myoma.  The  différent  fxrms  of  diffused 
fibro-muscular  hypertrophy  of  the  wall  uro  included  by  miiny  writers 
under  the  name  of  purcuchymatoun  metritis,  which  is  certainly  not  a 
good  terra,  since  tliey  arise  generally  by  a  slow  proce»*,  consisting  simply 
in  a  new  formation  of  smooth  muscular  fibres.  Vircliow  eon*i<ler>  this 
growth  as  a  hyperplasia  of  the  uterine  fibrn-nuiscular  ti^^uc,  wliich  is  a 
much  better  name;  and  he  describes  it  with  the  myomnla.  There  are 
according  to  this  author  two  varieties  :  the  one  soft  and  resembling  the 
uterine  wall  shortly  after  delivery,  a  comhtion  due  to  it^  vasculariiv  and 
abundance  of  muscular  fibres,  and  the  softness  of  the  connective  tissue  ; 
the  other  hard,  compact,  not  very  vascular,  and  containing  numerous  fasci* 
euli  of  dense  fibres. 

These  \'arieties  of  local  hypertrophy  often  follow  delivery,  especially 
when  the  nock  Inis  been  torn.  The  subacute  inflammation  succeeding

They  begin  in  the  muscular  wall.  They  are  generally  at  first  very 
vascular  and  soft,  later  becoming  indurated  in  con3ef|uence  of  the 
fibrous  organization  of  their  connec^ve  tissue.  Sometimes  the  intra- 
parietal  tumor.4  are  very  small,  round,  and  «[uite  hard.  At  the  be^nning 
the  fibres  of  the  tumor  are  directly  continuous  with  the  neighboring 
fibro-muscuiar  fai^ciculi  of  the  uterine  wall.  By  their  development,  these 
tumors  project  either  upon  the  external  surface  of  the  uterus,  when  they 
are  covered  by  the  peritoneum  (:iubparieUil  tumors)  ;  or  upon  the  intentai 
surface  of  the  uterus,  when  they  are  covered  by  the  raucous  membrane. 
Frequently  they  are  pedunculated  in  such  a  manner  as  to  be  united  to 
the  wall,  cither  by  a  large  and  vascular  or  very  nam>w  pedicle.  Myo- 
mata  projecting  into  the  uterus  are  frequently  called  fibrous  polypi.  The 
subperitoneal  tumors,  not  being  impeded  in  their  growth,  acquire  a 
very  large  size.  They  are  usually  multiple,  even  when  of  considerable 
size,  and  very  often  there  are,  at  the  same  time  with  subperitoneal 
tumors,  intra-parietal  tumors  and  polypi  projecting  into  the  cavity  of 
the  uterus;  at  times  they  are  so  numerous  as  to  cause  a  change  in  the 
shape  of  the  organ.  It  is  also  sometimes  difficult  to  find  the  cavities 
of  tlie  uteriLs,  owing  to  the  cavity  of  the  neck  being  entirely  cut  ofi" 
from  that  nf  the  body,  by  intra-parietal  myomata  projecting  at  the  point 
of  separation  of  the  two  cavities.  Tue  several  degenerations  which 
have  been  mentioned  in  Part  First,  as  occurring  in  myomata,  may  also 
occur  in  this  class  of  uterine  tumors,  especially  the  subperitoneal.  A 
carcinomatous  metamorphosis  of  a  uterine  myoma  has  been  seen  by  us 
in  a  case  of  carcinoma  of  the  peritoneum.  Virchow  has  also  observed 
carcinoma  in  a  myoma. 

Myomata  projecting  into  the  cavity  of  the  body  of  the  uterus  are 
either  hard  and  fibrous,  or  formed  of  a  softer  mu^^cular  tissue,  redder, 
more  vascular,  anil  having  large  vessels  ;  their  ablation  gives  rise  to 
hemorrhages  difficult  to  arrest.  The  former  of  these  intra-uterine  polypi 
sometimes  occasions  considerable  and  repeated  hemorrhages  of  the  mucous

membrane.  It  is  seldom  that  a  polypus  of  this  variet;  is  developed  in 
the  wall  of  the  cervix.  When  a  polypus  having  its  origin  in  the  body  of  the 
uterus  projects  into  the  neck  and  passes  through  the  lips  of  the  os  nteri, 
its  mucous  membrane  is  changed,  becomes  thicker,  and  is  covered  wiUi 
pavement  epithelium.  The  projecting  portion  covered  by  mucous  mem- 
brane sometimes  in  red,  inflamed,  and  ulcerated.  The  mucous  membrane 
is  entirely  destroyed  in  spots  varying  in  extent,  exposing  the  muscular 
tissue.  The  neighboring  mucous  membrane  fonna  a  sharply  cut  border  to 
the  ulcer  ;  it  is  red  or  red-brown,  and  much  inflamed  by  contact  with  the 
irritating  fluids  of  the  vagina.

fifth  or  Mxth  inontb,  by  a  process  of  gemmation  or  budding,  the  nnli- 
mentary  duct^  of  llie  lobules  are  apparent,  springin;^  from  the  central 
collection  of  cella.  These  Imda  are  increaacd  in  size  by  a  ci>ntiniiation 
of  the  cell  prolifcralioii,  but  as  yet  thcrp  is  do  attempt  at  the  develop- 
ment of  the  secreting  ncini.  During  childhood,  and  until  puberty,  the 
increntfi  in  the  number  of  duct«  is  very  idow,  Itnt  at  puberty,  in  the 
girl,  there  ic  a  rapid  increaiic  in  their  mimbpr  ;  while  in  man,  on  tlie 
other  hand,  there  li  no  further  ilevelopmeul,  except,  in  extremely  rare 
caacii.  there  may  even  be  an  atrophy  of  the  existing  ducle.  TIte  begin- 
ning at  the  formation  of  tho  secreting  structure  of  the  gland,  the  aeïiù, 
ia  noticed  in  the  femikle  at  puberty.  Yet  it  is  only  during  the  super- 
vention of  the  first  pregnancy  that  the  gland  attains  its  full  development. 
The  gland  retaina  tlua  structural  development  during  the  child-bearing 
life  of  tlio  woman,  becoming  somewhat  emaller  in  size  and  losing  a  few 
of  its  acini  during  the  period»  of  physiological  rest.  When  the  ineno- 
pfttiM  U  reached  there  is  an  entire  disappearance  of  the  »ecreling  acini, 
and  die  ^and  returns  to  its  embryonic  state,  fatty  tissue  being  suljstituted 
for  the  glandular  tissue.

lobules  to  be  as  large  as  in  the  condition  oî  full  evolutjon.  The  acini 
were  also  of  much  the  same  shape  and  size  as  in  the  secreting  gland. 
But  their  cellular  contents  were  very  different.  In  each  acinus  were 
found  variously  shaped  cellular  bodies,  usually  corre- 
sponding in  size  to  that  of  an  epithelial  nucleus  ; 
also,  a  number  of  ring-like  forms  of  a  grayish  un- 
stained granular  appearance,  with  the  variously 
shaped  cellular  bodies  placed  on  their  periphery, 
were  seen.     (i>,  fig.  335.     C,  fig.  336.) 

"The  significance  of  these  appearances  is  better 
comprehended  from  another  preparation.  (B,  fig. 
ÎJ35),  Here  the  acinus  presents  a  profile  view  of  the 
epithelium,  which  shows  the  cells  arranged  as  a  com- 
plete circlet  adhering  to  the  circumference  of  the  aci- 
nus. In  many  of  the  acini  were  seen  irregular  collec- 
tions of  cells  free  in  the  lumen  of  the  acinus.  In  other 
parts  of  the  same  preparation  were  observed  cells  of 
which  C,  fig.  336,  is  a  drawing.  The  cells  in  êitit 
arc  vacuolated  cells,  usually  possessing  Ibc  thin  and 
mostly  uncolored  rin^  of  the  vacuole  (?ignet-ring  type). 
Other  cells  undergoing  the  process  of  vacuolation  are  found.  There  is 
thus  a  gradual  transition  from  the  perfect  mammary  epithelium  to  the 
forms  that  characterize  the  various  stages  of  the  involution  processes." 

The  secretion  of  the  mammary  gland  formed  during  its  physiological 
activity  is  milk.  Anatomically  considered,  it  is  a  fluid  in  which  are 
suspended  vast   numbers   of  fatty 

globules,  in  other  words,  an  emui-  ^'g-  ^3'^- 

sion. 

Examined  with  the  microscope, 
there  are  seen  numerous,  distinct, 
and  separate  oil-globules,  varying 
in  size  from  0.002-3  mm.  to  O.tiOOO 
mm.  By  the  addition  of  acetic 
acid,  the  globules  lose  their  indi- 
viduality and  coalesce,  forming 
large  oil-drops;  therefore,  each 
globule  may  be  considered  as  a 
minute  drop  of  oil  inclosed  in  a 
delicate  membrane  of  some  albu- 
minous substance,  probably  ca.sein. 

Themicroscopicappcarancoofthe 
fluid  secreted  during  the  last  days 
of  gestation,  or  immediately  afier 
labor,  the  colostrum,  contains,  in 

addition  to  the  fat  globules, other  bodies, spherical  in  shape, from  the  0.0151 
to  0.0504  mm.  in  diameter,  composed  of  a  collection  of  oil  globules,  held 
together  by  a  cement,  and  sometimes  containing  a  nucleus;  they  arc  also 
said  to  possess  the  power  of  contractility  to  a  slight  extent.  These 
bodies  are  known  as  the  colonlriirn  rorpunrles.

F  We  have  «ever  seen  them,  but  they  havo  been  reported  by  other  patho- 
logists, especially  Virchow.

B.  Lksioss  of  Tns  Fibbo-muscular  Wall. 

The  fibromuneular  wall  of  the  uterus  generally  escapes  involvement 
I'lD  catiirrhal  inllammation,  and  it  is  markedly  alfecled  only  in  puerjieral 
1  inflammation.  The  veins  are  attacked  with  inflammation,  and  ahscemea 
imay  bo  developed  in  their  wall. 

1     Lesions  of  the   uterine  wall   mostly  consist  in  a  new  formation  of 

'smooth  muscular  and  fibrous  tissue,  whiuh  occasions  either  a  general  or 

i«  local  hypertrophy  of  the  wall.     A  hical   hy|icrtrophy  when  .«harjdy 

limited  may  be  regardai  a»  u  myoma.     The  diffiTent  form»  of  diflused 

,  fibro-mu-fcutar  hyjiertrophy  of  the  wall  art-  included  hy  many  wriiera 

I  under  the  name  of  parenchymatous  metritifi,  which  U  certainly  not  a 

'  good  term,  since  they  arise  ^ttenerally  by  a  slow  proce,ss,  consisting  simply 

in  a  new  formation  of  smooth  muscular  fibrea,     Virchow  considers  this 

growth  as  a  hyperplasia  of  the  uterine  fibro- muscular  tissue,  which  is  a 

much  botter  name  :  and  he  describes  it  with  the  myomata.     There  arc 

jaccording  to  this  author  two  varieties:    the  one  soft  and  resembling  the 

Interine  wall  shortly  after  delivery,  a  condition  due  to  its  vascularity  and 

|kbundance  of  muKcular  fibres,  and  the  softness  of  the  connective  tissue; 

he  other  hanl, compact, not  very  vascular,  and  containing  numerous  fusci- 

îuli  of  denae  fibre*.

They  begin  in  the  muscular  wall.  They  are  generally  at  first  very 
vascular  and  sofl,  later  becomin^r  indurated  in  consequence  of  the 
fibrous  organization  of  their  connective  tissue.  Sometimes  the  intra- 
parietal  tumors  are  very  small,  round,  and  ijuite  hard.  At  the  beginning 
the  fibres  of  the  tumor  are  directly  continuous  with  the  neighboring 
fibro-muacular  fasciculi  of  the  uterine  wall.  By  their  development,  these 
tumors  project  either  upon  the  external  surface  of  the  uterus,  when  they 
are  covered  by  the  peritoneum  (aubparietal  tumors);  or  upon  the  internal 
surface  of  the  uterus,  when  they  are  covered  by  the  mucous  membrane. 
Frequently  they  are  pedunculated  in  such  a  manner  as  to  be  united  to 
the  wall,  either  by  a  large  and  vascular  or  very  narrow  pedicle.  Myo- 
mata  projecting  into  the  uterus  are  frequently  called  fibrous  polypi.  The 
subperitoneal  tumors,  not  being  impeded  in  their  growth,  acquire  a 
very  large  size.  They  are  usually  multiple,  even  when  of  considerable 
size,  and  very  often  there  arc,  at  the  same  time  with  subperitoneal 
tumors,  intra-parietal  tumors  and  polypi  projecting  ïntc  the  cavity  of 
the  uterus;  at  times  they  are  so  numerous  as  to  cause  a  change  in  the 
Bhape  of  the  organ.  It  is  also  sometimes  difficult  to  find  the  cavities 
of  the  uterus,  owing  to  the  cavity  of  the  neck  being  entirely  cut  off 
from  that  of  the  body,  by  intra-parîetat  myoraata  projecting  at  the  point 
of  separation  of  the  two  cavities.  The  several  degenerations  which 
have  been  mentioned  in  Part  First,  as  occurring  in  myomata,  may  also 
occur  in  this  class  of  uterine  tumors,  especially  the  subperitoneal.  A 
carcinomatous  metamorphosis  of  a  uterine  myoma  has  been  seen  by  us 
in  a  case  of  carcinoma  of  the  peritoneum.  Virchow  has  also  observed 
carcinoma  in  a  myoma. 

Myomata  projecting  into  the  cavity  of  the  body  of  the  uterus  are 
either  hard  and  fibrous,  or  formed  of  a  softer  muscular  tissue,  redder, 
more  vascular,  and  having  largo  vessels;  their  ablation  gives  rise  to 
hemorrhages  difficult  to  arrest.  The  former  of  these  intra-uterinc  polypi 
sometimes  occasions  considerable  and  repeated  hemorrhages  of  the  mucous

membrane.  It  ia  Beldom  that  a  poljpus  of  this  variety  is  developed  in 
the  wall  of  the  cervix.  When  a  polypus  having  its  ori^nic  the  body  of  the 
utorua  projects  into  the  neck  and  passes  through  the  lips  of  the  os  uteri, 
ltd  mucous  membrane  ia  changed,  becomes  thicker,  and  is  covered  with 
pavement  epithelium.  The  projecting  portion  covered  by  mucous  mem- 
brane soraetimea  is  red,  inflamed,  and  ulcerated.  The  mucous  membnne 
is  entirely  destroyed  in  spots  varying  in  extent,  exposing  the  muscolir 
tissue.  The  neighboring  mucous  membrane  forma  a  sharply  cut  border  to 
the  ulcer  ;  it  is  red  or  red-brown,  and  much  inflamed  by  contact  with  the 
irritoting  fluids  of  the  vagina.

ioiher  hand,  there  is  no  further  dcvclopment,  except,  in  extremely  rare

Tentinn  »f  the  firi^t  jiregnancy  that  the  gland  attains  its  full  devLdopmeut. 

The  gland  retains  Uiis  Mtriiclural  <levclopment  during  the  child-bearing 

»life  of  the  woman,  becoming  souii-'what  smaller  in  size  and  losing  a  tew 
of  its  acini  during  the  periods  of  physiological  rest.  When  the  meno- 
pause is  reached  there  ia  an  entire  disappearance  of  the  secreting  acini,

lobules  to  be  as  large  as  in  the  condition  of  fui!  evolution.  The  acini 
were  also  of  much  the  same  shape  and  size  as  in  the  accreting  gland. 
But  their  cellular  contents  were  very  different.  In  each  acinus  were 
found  variously  shaped  cellular  bodies,  usually  corre- 
sponding in  size  to  that  of  an  epithelial  nucleus  ; 
also,  a  number  of  ring-tike  forms  of  a  grayish  un- 
stained granular  appearance,  with  the  variously 
shaped  cellular  bodies  placed  on  their  periphery, 
were  seen.     (i>,  fig.  335.     C,  fig.  330.) 

"The  significance  of  these  appearances  is  better 
comprehended  from  another  preparation.  (J5,  fig. 
335),  Here  the  acinus  presents  a  profile  view  of  the 
epithelium,  which  shows  the  cells  arranged  as  a  com- 
plete circlet  adhering  to  the  cireumferencc  of  the  aci- 
nus. In  many  of  the  acini  were  seen  irregular  collec- 
tions of  cells  free  in  the  lumen  of  the  acinus.  In  other 
parts  of  the  same  preparation  were  observed  cells  of 
which  C,  fig.  836,  is  a  drawing.  The  cells  in  tilu 
are  vacuolated  cells,  usually  possessing  the  thin  and 
mostly  uncolorcd  ring  of  the  vacuole  (?ignet-ring  type). 
Other  cells  undergoing  the  process  of  vacnolation  are  found.  There  is 
thus  a  gradual  tranaition  from  the  perfect  mammary  epithelium  to  the 
forms  that  characterize  the  various  stages  of  the  involution  processes," 

The  secretion  of  the  mammary  gland  formed  during  its  physiological 
activity  is  milk.  Anatomically  considered,  it  is  a  fluid  in  which  are 
suspended  vast   numbers  of  fatty

globules,  in  other  words,  an  emul- 
sion. 

Examined  with  the  microscope, 
there  are  seen  numerous,  distinct, 
and  separate  oil-globules,  varving 
in  size  from  0.0023  mm.  to  0.Ô090 
mm.  By  the  addition  of  acetic 
aoid,  the  globules  lose  their  indi- 
viduality and  coalesce,  forming 
large  oil-drops  ;  therefore,  each 
globule  may  be  considered  as  a 
minute  drop  of  oil  inclosed  in  a 
delicate  membrane  of  some  a!bu- 
minouB  anhatance,  probably  casein. 

ThemicroBCOpicappearanccofthe 
fluid  secreted  during  the  last  days 
of  gestation,  or  immediately  after

addition  to  the  fat  globules, other  bodies, spherical  in  shape, from  the  0.01 51 
to  0.0564  mm.  in  diameter,  composed  of  a  collection  of  oil  globules,  held 
together  by  a  cement,  and  sometimes  containing  a  nucleus  ;  they  are  also 
said  to  possess  the  power  of  contractility  to  a  alight  extent.  These 
bodies  are  known  as  the  colostrum  rorpv»cIe».

forming  a  single  layer,  or,  as  in  the  first  months  of  gestation,  their  cells 
are  larger  and  granular.  In  every  ease  ihe  canaU  are  elongated,  in 
order  to  keep  pace  vith  the  hypertrophy  of  the  connective  tissue,  but  the 
alteration  is  principally  a  fibrous  thicl>emng  of  the  connective  tissue,  and 
not  a  leeion  either  primarily  or  principally  of  the  epithelium.  Sometimes 
there  are  lobules  of  fat  in  the  gland,  but  generally  they  are  not  present. 
Manse  obser^'od  that  the  galactophonjus  duels  were  much  dilated,  so 
much  so  as  to  receive  the  extremity  of  the  finger.  Hypertrophy  of  the 
mammary  gland  consista  mostly  of  a  new  formation  of  hbrcius  ti&suo.  In 
most  connective-tissue  new  formations,  the  glandular  ducts  and  acim  are 
dilated  :  this  dilatation  is  analogous  to  that  of  the  biliary  ducts  in  cirrhosis 
of  tlie  liver.  By  the  same  prOMM,  small  cy»U>  may  form  from  the  n'ten- 
tion  of  the  glandular  products,  when  a  galactophoroud  duct  is  isolat«d  in 
the  middle  »f  fibrous  tissue. 

GALAcrocG[.B. — Galactocele  is  a  tumor  caused  by  the  accumulation  and 
retention  of  milk  in  a  part  of  the  mammary  gland,  eitiier  at  its  centre  or 
periphery.  Its  development  coincides  with  lactation,  and  it  may  spon- 
taneously disappear  after  the  cessation  of  this  function.  'Hie  milk  is 
either  normal,  or  curdled  and  creamy  ;  it  is  contained  in  a  single  sac,  or 
partitioned  by  bands,  (pvinjj  it  au  alveolar  appearance.     The  sac  com-

Sarcomata  of  the  hreast  are  very  easily  dîstïn;;utshe<l  from  carcinnniata

tumors  oflen  return  after  ablation.  When  a  cjstic  sarcoma  has  been  re- 
moved at  the  first  operation,  with  the  entire  breast,  the  recurrent  formation 
)8  found  to  be  a  sarcoma  without  cysts.  This  is  explained  b;  the  whole 
of  the  gland  being  removed  at  the  first  operation. 

Secondary  sarcomatous  nodules  of  pleura,  lungs,  bones,  and  otiier 
organs  are  somottmes  met  with  at  autopsies  of  persons  who  had  been 
operated  upon  for  sarcoma  of  the  mammarj  gland. 

Myxoma. — Mj;comata  of  the  mammary  gland  are  not  unfrequently 
seen  ;  they  differ  from  sarcomata  only  by  the  nature  of  the  tissue  com- 
posing them,  for  their  situation  in  relation  to  the  glandular  acini  and 
canals  is  the  same.  Cystic  myxomata  are  tlie  most  frequent  (for  His- 
tology, see  Part  First,  page  89). 

Klyxomata  of  the  breast  are  essentially  benign  tumors  ;  tliey  do  not  con- 
tract adhesions  with  the  skin,  and  at  times  may  be  completely  enucleated, 
appearing  as  if  contained  in  a  serous  membrane  which  separates  them 
from  the  surrounding  tissue.  In  a  case  recently  seen  by  us,  the  large 
tumor,  a  papillary  myxoma,  presented  in  its  deeper  portion  large  masses 
situated  in  a  serous  cavity,  one  wail  of  which  covered  the  nodules.     We

had  here  to  do  with  a  large  serous  bursa,  the  anterior  wall  of  which  be- 
longed to  the  tumnr,  while  the  |>03torior  wall  was  in  connection  with  the 
connective  tissue  situated  behind  it.  The  cells  upon  the  surface  of  this 
cavity  were  thin  and  Sat.  From  this  arrangement  we  were  led  to  think 
that  this  serous  membrane  was  the  serous  cavity  or  large  lymphatic 
lacuna  situated  beneath  the  breast,  for  it  was  impossible  from  its  location 
to  suppose  that  it  was  formed  by  galactophnrous  canals  or  glandular  acini. 
It  is  very  probable  that  the  clefts  and  cavities  into  which  the  new  forma- 
tions of  fibromata,  sarcomata,  and  myxomata  project,  are  not  only  the

microscopic  examinatioD  in  one  of  the  cases  proved  that  the  periphery  of 
the  lympnatic  vessels  througliout  their  entire  course  consisted  of  a  ear- 
ctnomatotis  tissue  with  alvcoti  and  characteristic  cells.  We  have  alreadT

tu!jes  ennliiininj  regularly  nrrnii;;('d  cylindrical  cells.  For  tlie^c  reawiiui

fltood.  and  further  invesli;^ation  is  necessary  to  determine  ttieir  exact 
nature.  We  cannot  too  strongly  recommend  to  those  making  a  claasîfi- 
calion  of  mammary  tumors,  the  examination  of  the  tumors  which  return 
in  the  ciciitrix  after  the  complete  removal  of  the  gland,  for  (hey  give 
rooit  iraporiant  information  of  the  nature  of  the  primary  tumor.  iTie 
degenerated  neighhoring  connective  tissue  and  lymphatic  glands  shouM 
also  be  carefully  examined. 

From  the  foregoing  deseriptionx  it  is  svi-n,  that  in  fibromata,  myxomats, 
sarcomata,  and  carcinomata,  the  initial  lesions  in  the  gland  and  excretory 
ducts  of  the  breast,  have  a  grent  mmhi^v  ;  for  example,  in  nil  the« 
tumors  vcgelatiomi  grow  into  the  intfrinr  of  the  gataetophorous  ducts, 
and  cysls  have  their  origin  hy  the  distension  of  the  ducts  and  acini. 
Tliese  cysts  and  vegetations  are  not.  therefore,  cbaraclcrislic  of  any 
particvdar  tumor,  and  in  order  to  determine  the  nature  of  the  new  foro»- 
tion,  examination  of  other  portions  must  he  made — that  is,  of  tlio  co» 
ncctive  tissue,  which  is  in  each  changed  into  a  special  tissue. 

Enciios'droma. — The  encbondromata  of  the  mammary  gland  %rc  ren 
rare  tumors;  a  few  only  have  been  reported.  In  a  specimen  met  villi 
by  Wagner,  there  were  found  cartilaginous  masses  in  a  carcinoma.

CYBTS    OF    THE    MAUMA.  715 

Adesoua. — The  eharacterj  of  adenoma  of  the  breast  have  been  ;;ivca 
ill  Part  First  (see  p.  161).     They  were  for  a  long  time  eonaideved  by 


Ve)peau  as  synonymous  with  benign  tumors  of  the  breast,  among  wliîch 
«ere  confounded  fibromata,  my.'iomata,  sarcomata,  and  true  adenomata. 

Melanotic  Tumors  of  the  Breast. — See  Part  First,  pages  329, 330. 

Epithelioma! A,  with  pavement  cells  and  pearly  bodies,  are  seldom 
met  with  in  the  mammary  ^land.  Tney  occur  especially  as  a  new  forma- 
tion, having  its  origin  from  the  skin  in  the  region  of  the  nipple,  where 
are  found  numerous  and  large  sebaceous  glands.  These  tumors  do  not 
differ  in  their  mode  of  development  or  extension  from  epitheliomata  of 
the  skin,  and  especially  those  of  the  lips. 

Cysts. — The  cysts  occurring  in  adenomata,  sarcomata,  fibromata, 
myxomata,  and  carcinomata,  have  already  been  described.  We  have 
now  to  consider  cysts  due  to  the  retention  of  the  secretion  of  tlie  galac- 
tophorous  canals  and  acini.  Their  causes,  as  yet  not  welt  understood, 
have  been  associated  with  the  partial  obliteration  of  a  duct  from  the 
fibrous  atrophy  of  involution  of  the  gland,  from  cicatrices  following  an 
operation  upon  th  '  breast.  The  majority  of  se ro- sanguineous  cysts  are 
associated  with  tumors,  such  as  sarcomata  or  myxomata;  yet  they  may 
follow  contusions. 

Several  cases  of  dermoid  ciftt»  have  been  reported,  especially  that  by 
Velpeau,  which  should  be  classed  among  the  dermoid  cysts  of  the  first 
variety  (see  page  304);  another,  reported  by  Albers,  contained  hairs  in 
the  midst  of  a  sebaceous  mass. 

Hydatid  c}/»t»,  with  eehinococci  developed  in  the  connective  tissue  of 
the  mammary  gland,  are  aho  of  very  unfrei^ncnt  occurrence.

by  adipose  vesicles  and  capillary  bloodvessels.  Later  a  cavity  is  formed 
in  the  tube,  which  in  a  section  of  the  skin  of  a  new-bom  child  is  seen  aa 
a  narrow  lumen  surrounded  by  a  row  of  distinct  prismatic  cells,  implant«d 
upon  a  thin  wall.  The  excretory  duct  ascends  vertically  into  the  derma 
and  reaches  the  eptdennic  layers  through  which  it  passes  in  a  spiral  man- 
ner. In  its  dermal  portion  it  is  lined  with  cells  similar  to  those  of  the 
rete  mucosum,  and  in  the  fœtus  these  cells,  like  those  of  the  rete  muco- 
Bum,  are  loaded  with  glycogen.  In  some  regions  the  duct  is  provided 
with  smooth  muscular  fibres  longitudinally  arranged.  The  sudorific 
glands  seem  to  play  an  important  part  in  the  development  of  a  number 
of  cutaneous  lesions. 


8eot.II.-  Œdematou  Inflltrationi  of  the  Skin. 

Œdematous  infiltrations  of  the  skin  are  of  two  kinds,  and  include; 
Ist.  Simple  œdema,  which  simply  consista  in  the  eftusion  of  an  albumin- 
ous serum  between  the  connective  tissue  fasciculi  of  the  derma.  2d.  In- 
jiammatory  œdema,  caused  by  the  accumulation  of  lymph,  containing 
coagulabte  fibrin  in  the  interstices  of  the  same  fasciculi.  We  consider 
these  two  forms  of  œdema  in  one  paragraph,  although  pathologically 
they  correspond  to  two  aeries  of  phenomena  essentially  different. 

A.  Simple  Œdema,  Serous  Infiltration  of  the  Skin. — It  is  known, 
that  when  the  pressure  in  the  capillaries  exceeds  a  certain  limit,  diape- 
dcsis  occurs  and  œdema  is  the  result.  The  increase  in  pressure  may 
take  place  from  two  causes:  either  because  the  passages  which  carry  off 
the  fluids  are  not  free,  in  consequence  of  a  venous  obstruction  ;  or  because 
the  contractile  vessels  are  in  a  state  of  atony. 

It  is  to  the  latter  cause  that  primary  œdema  of  the  akin  ia  due.  The 
elevations  of  urticaria,  and  of  papulous  erythema,  are  nothing  more  than 
small  points  of  circumscribed  œdema.  They  are  always  accompanied  by 
extravasation  of  blood.  The  fluid  poured  out  at  the  time  of  the  diape- 
desis,  always  contains  a  number  of  red  blood  corpuscles.  Hence,  in 
cutaneous  œdema  produced  by  the  paralysis  of  a  nene,  the  akin  at  the 
location  of  the  lesion  sometimes  has  all  the  colors  of  an  cccliymosts,  and 
the  papulse  of  urticaria,  for  example,  may  have  a  hemorrhagic  character. 
This  variety  is  dcâcribed  by  Willan  and  Rayer  ds  purpura  urtican». 

The  papuiai  of  urticaria  are  a  type  of  local  œdema  of  the  skin.  The 
white  elevation  corresponds  to  the  iuBltraCed  portion  of  the  derma, 
the  pink  areola  to  the  vascular  congestion  which  surrounds  it.  Tne 
redness  always  precedes  the  appearance  of  the  papulje  The  white 
color  is  due  to  the  interstitial  distension  of  the  derma  by  serum,  as  may 
be  demonstrated  by  injecting  water  into  the  skin  witii  a  hypodermic 
syringe,  when  there  is  formed  the  pale  pniriginoua  swelling  of  urticaria. 
The  pruritus  from  hypodermic  injection,  comparable  to  that  of  urticana, 
is  in  reality  due  to  the  action  of  the  water  upon  the  nerves. 

The  white  spots  upon  the  surface  of  the  skin  in  anasarca,  isolated  or 
running  together  so  as  to  form  networks,  very  similar  to  those  of  urticaria,

The  phenomena  ho  cIokc  to  inflammation  cannot  continue  for  a  long 
time  in  tiMues  withunt  a  chronic  inflammation  rvs'illîn;;.  Therefore  the 
history  of  a  chronic  œdema  and  chronic  dermatitis  are  intimately  con- 
iiecie<l,  the  fonn«r  always  by  it-t  Ion;;  duration  canaiiig  the  latter. 

To  rejioat,  when  the  OMlecna  of  the  skin  'u,  oocasiont-d,  cillicr  in  conse- 
quence of  local  nene  pxralyn»,  or  by  the  extension  of  a  subjacent  ucdema,

of  the  derm  ;  2il.  Mij^raliou  of  white  blood  corpuscles  and  a  few  red

nhich  is  in  correlation  with  the  elimination  of  the  cedematons  products 
to  such  an  extent,  that  in  some  cases  the  dilated  lymphatic  vessels  are 
irritated  alon^  their  cour^,  and  are  seen  as  white  cords.  Tliis  always 
occurs  in  an  intense  <xdema  of  the  skin  of  an  entire  limb,  a«,  for  example, 
in  phUymnia  alha  di<hn». 

B.  *Kt>KMA  OP  THE  LvMpn  P*BSAnKS. — Tliis  has  been  described  by 
several  writers,  especially  by  Vircliow  as  feuwj'hfe-fmagia,  and  by  Kind- 
Heiach  a*  fympkan;iieiytatif  pachydermia.  \i  times  alao,  when,  in  con- 
ae(|ueDce  of  a  |>rotonged  œdema,  the  lym]>hatic  canals  and  the  corre^j^ond- 
iiiglympb  glands,  for  a  long  time  irritated,  contract  in  the  same  manner 
as  a  cicatrix,  this  variety  of  œdema  is  often  seen  to  follow  anaAnrca. 
Bio  skin  is  hard  mammillated,  reddish-brown;  upon  nunctiirc,  there  es- 
capes a  fluid  spontaneously  coa;;ulable  in  the  utr  ;  and  in  sections  of  Uie 
skin,  after  baracning  in  alcohol,  the  derm  i»  seen  filled  with  lymph  wliich, 
afVr  coagulation  by  the  alcohol,  remaiug  in  all  the  interstices  of  the 
fibrous  ttasue,  distending  the  meshes  like  an  injection  of  gelatine.  The 
lymphatics  are  gapiug  and  filled  with  lymph  clots;  very  freijuently  this 
variety  of  wdema  rapidly  occa«iotis  in  the  .'«kin  a  chronic  dermaciUs, 
which  extends  to  tiic  subcutaneous  tissue  and  add»  to  tJie  rigi<lity  of 
the  skin  already  ongorged  with  fluid.  The  cellular  infiltration  is  as  in- 
tense as  in  .simple  oedema,  only,  instead  of  an  alliuminous  serum,  it  ia 
lyropb  which  61U  the  lacunar  spaces  of  the  dorm. 

This  stagnation  of  the  lymph  dependent  upon  the  impermeability  of  Iho 
lymphatic  glands  which  have  usually  become  fibroiis,  froijiicnlly  occasions 
the  appearance  of  varicose  lymphatics  in  the  skin.  The  œdematous  in- 
duration observed  in  tlicso  cases  bas  been  considered,  by  several  denna- 
tologisis,  as  a  variety  of  elopbantiasis.  This  name  may  be  retained,  if 
it  is  applied  to  every  cbronic  infiammation  or  induraliOD  of  the  skin  aa  a 
generic  term.

nation of  diffuse  inBaroimtioni^,  and  when  it  occuni  the  suppuration  of 
the  denn  does  not  take  pluci*  over  large  surfauen,  but  in  foci  more  or  less 
Hcattcred.  Each  of  the  «mail  dermic  «Imcvhscs  is  «iinilar  to  that  pro- 
duced i»  Uio  »kin  around  a  foreign  body — around  a  xoton,  for  example. 

In  some  intlammations,  when  Kuppuration  occur»  the  cello  are  seen  in 

f laces  to  accumulate  in  the  mvi^hea  of  the  derm.  The  celU  come  either 
rora  a  diapedesia  of  the  white  iilnod-cor|mscloa,  or  from  a  division  of  the 
fixed  cells;  they  become  fatty  degenerated,  and  are  hut  slightly  colored 
with  carmine.  These  cells  are  dead,  and  constitute  small  foreign 
bodies  in  the  skin.  Gencrallv  they  are  collected  into  foci  at  varying 
distances  from  the  surface,  wb^o  the  eurroun<ling  fundamental  substance 
(eUietic  Bbrea  and  conncctivc-tissue  fibre»)  of  the  derm  is  absorbed. 
Thus  résulta  a  small  cavity  Sllcd  witb  pns,  excavated  in  the  derm.  Sur- 
rounding it  there  exists  a  con<r(;«tive  inflainmntinn  of  the  connective  tissue. 
The  bloodvessels  and  csjwcially  the  arteries  <if  small  calibre,  are  second- 
arily infiamcil;  endarteritis  diminishes  the  ealihre  of  the  vesucts,  nnil  in 
conse<|ucn«e  the  amount  of  blood  to  the  part  is  lessened.  'Die  jmndent 
fociis  Ls  enlarged  at  the  expense  of  tlie  surrounding  slightly  vascular  tie.fue, 
and  when  it  reaches  the  surface  ulceration  occurs. 

The  method  of  forni-ttion  of  ;tr»nulBtion  tissue  at  tlie  cutaneoua  surface, 
and  the  process  of  cicalriitation  have  been  considered  (pagas  tifl,  71). 
According  to  the  invcàligations  of  Keverdin.  tlie  ]jresetice  of  transplanted 
epidermic  cells  upon  a  granulating  wound  of  the  sktn  occasions  an  active 
reproduction  of  the  epithelium  around  the  grafted  cells.  The  epidenme 
ceils  appear  to  act,  not  bj  multiplying  through  division,  hut  bv  their 
lircscncc,  which  causes,  as  it  were,  an  epidermic  evolntion  of  the  sur. 
'  rounding  embryonic  cells,  for  the  graft  does  not  itself  show  anr  signs  of 
activity,  but  is  soon  destroyed  in  the  midst  of  the  new  epithelial  tissue 
which  it  bus  caused  to  be  developed.

an  abundant  celhdar  inliltnition  between  the  connective  tissue  fasciculi 
of  the  lierai,  a  delicate  tihrinoiw  reticulum  is  seen  which  incloses  in  its 
meshes  the  ttimderiiig  cells.  Sometimes  fibrin  is  exuded  in  abundance,

stellate  lymph  spaces  form,  in  sections  transverse  to  the  direction  of 
the  fasciculi,  lar^e  stellate  spaces  lined  with  endothelium.  With  tliis 
hvpcrtrophy  of  the  derm  corresponds  a  relative  atrophy  of  tlie  p»]>ill%. 
'Ac  epidermic  layers  arc  thin,  and  the  nuclei  of  the  cells  are  frefpiejitly 
atrophied  by  the  dilatiition  of  tbe  nucleoli,  whence  there  is  an  almost 
coiilinnal  di-nipiumatîon  from  the  surface  of  the  skin  so  inHamcd.  Tbe 
subcutaneous  adipose  tissue,  blended  with  the  derm,  is  hard,  because

reaemble  the  papiilse  upon  the  tongue  of  a  niminating  animal.  Usually 
the  akin  is  considerably  thickened,  wrinkled,  and  folded.  In  sections  from 
the  skin,  in  vhich  the  lymphatics  have  been  injected,  and  colored  with 
picro-carmine,  the  papillie  are  seen  enormously  enlarged,  formed  of  em- 
bryonic connective  tissue  (mucous  tissue)  analogous  to  that  fomiing  the 
Whartonian  jelly,  in  which  run  delicate  vessels  and  lymphatics,  without 
special  walls,  as  simple  lacunœ  lined  with  endothelium.  In  the  derm 
the  meshes  are  filled  with  embryonic  elements,  and  the  small  cells  at 
many  points  arc  undergoing  division  ;  generally  an  innumerable  number 
of  newly.formed  capillaries  are  seen.  These  embryonic  vessels  are 
especially  abundant  in  the  deep  parts  of  the  skin  around  the  sudorific 
glands. 

This  abundant  formation  of  new  vessels  is  especially  seen  after  chrome 
oedem&s.  In  the  interior  of  the  derm,  the  lymphatic  capillaries  are  also 
much  dilated,  and  gaping  upon  section. 

The  preceding  form  of  diffiiaive  dermatitis  constitutes  one  of  the  varie- 
ties of  elephantiasis  Arabum.  Very  different  chronic  inflammations,  bow- 
ever,  have  been  classed  under  this  name.  The  general  law  of  develop- 
ment of  elephantiasis  is  not  yet  determined  ;  but  it  is  known,  that 
when  congestive  inflammations  are  repeated,  or  prolonged,  or  frequently 
return,  as  in  erysipelas  or  œdema,  the  skin  becomes  hypertrophied,  and 
an  elepbantiasic  swelling  is  produced.  In  every  case  which  we  have 
seen  during  seven  years,  the  only  constant  lesion  has  been  dilatation  of 
the  lymphatic  capillaries;  the  variety  of  chronic  dermatitis  has  varied 
considerably. 

3.  Elephantiati»  Arahtm. — It  is  seen  from  the  foregoing  descrip- 
tions, that  chronic  difl'use  dermatitis,  whatever  may  be  its  cause,  has  a 
tendency  to  occasion  hypertrophy  of  the  skin. 

a.  If  œdema  has  continued  for  a  long  time,  there  is  produced,  over  a 
large  extent  of  surface,  an  indurated  engorsiemcnt,  due  to  stasis  of  the 
lymph  in  the  connective  tissue  spaces,  in  the  dilated  lymphatic  capillaries, 
and  in  the  alTerent  lymphatic  trunks  of  the  glands.  The  latter  are  trans- 
formed into  impermeable  fibrous  tissue,  and  they  exert  considerable  in- 
fluence in  the  production  and  in  the  continuation  of  elepbantiasic  dematitis 
(lymphangiectatic  pachydermia  of  Rindfleisch  ;  lymphatic  elepbantiasic 
cedema).  This  variety  is  secondary  to  repeated  œdemas,  and  is  not 
unfrei|uent  in  the  lower  extremities  of  persons  with  chronic  heart  disease. 
Its  most  frequent  seat  is  the  skin  of  the  scrotum,  penis,  and  prepuce. 

h.  A  second  variety  is  characterized  by  a  retuni  to  the  embryonic 
state  of  the  entire  hypertrophied  derm,  with  the  formation  of  large 
lymphatic  lacunce  in  the  granulation  tissue  into  which  the  skin  baa  been 
transformed.  This  variety  has  been  briefly  described  under  lymphan- 
giomata  (see  p.  141,  fig.  105).  The  seat  is  also,  like  the  preccdin;;  va- 
riety, usually  upon  the  genitals  (skin  of  the  penis,  clitoris,  labia  majora). 

c.  A  third  variety  has  been  described,  and  consists  in  an  enormous 
increase  in  thickness  of  tlie  derm,  due  to  a  multiplication  of  the  con- 
nective tissue  fasciculi  and  elastic  network;  frequently  the  smooth  mus- 
cular fibres  disseminated  in  small  numbers  through  the  derm,  according  to 
some  pathologists,  eousiderahly  increase  in  number  and  form  in  the  deep 
parts  of  the  skin  superimposed  layers  of  fibres  running  in  difierent  direc-

TllK  Skix:  1)tiu.j;  Axn  lli.is-n:B8. — AVhen  the  inflammatory  œdema  at 
any  point  Îb  of  aueh  intensity  that  the  lenHion  of  the  fluid  is  so  grejit  as  to 
overcome  the  resistance  of  the  cpidcmiis,  tlie  latter  yields  and  is  elevated 
into  the  form  of  a  bliat«r  or  bulla.  These  two  elcmentarj'  lesions  differ 
only  in  their  size  ;  the  process  of  tbcir  formation  is  identical. 

Tlic  point  of  least  resistance  of  the  epidermic  layers  is  the  jrrniiHUr 
layer,  lyinj;  between  the  vpdennic  cells  united  by  keratin  and  tiie  spinous 
ceils  of  the  rete  roucosum  intimately  united  tnj;eHier.  It  is  at  the  level 
of  this  }rranular  layer  that  the  epidermic  layers  yield  and  are  sepa. 
rated.  The  fluid  of  inflammatory  œdoma  is  now  ooUectod  into  a  bulla, 
and  conttiins  white  bloud  «orpuitcles  (wandering  cellx),  a  very  few  r«d 
disks,  and  a  tibrinogcaic  aubatanoe  wliicti  forms  a  fibrinous  reticulum 
inclosing  the  cellular  elements.  The  deeper  layers  of  the  rete  roucosum 
are  infiltrated  with  the  migrating  cells  which  subse'inently  penetrate  into 
the  bulla,  and  which  are  identical  with  those  infiltrating  the  papillie. 

In  some  varieties  of  herpes  (_hemorrhaffip  intter,  efani/renoun  Zftttr), 
it  is  almost  pur«  blood  which  fills  the  vesiclos  :  in  neuralgic  xostcr  ^ero 
are  always  found  one  or  more  resiclei  having  a  sanguineous  color  (Lnllier). 

The  evolution  of  a  pemphigus  bulla  or  of  a  blister  is  very  simple.    The

ViairLKH. — The  veaiclea  of  ecxenia — those  which  form  «pnn  the  sur- 
face of  an  eryaipelatona  skin,  or  those  piWuced  artificially  hy  Croion 
oil — arc  formed  by  a  process  very  different  from  ilie  foregoing.  The» 
arc  formed  iu  the  substance  of  the  rete  mucosum.  In  the  protoplaan  of 
the  s]ûnouF  cells  aro  developed  highly  refracting  opalescent  globules,  not 
colored  by  canoioc:  as  tlicy  increase,  tlicy  piisli  the  nucleus  to  the  peri- 
pliery.  The  cells  are  transformed  into  enormous  vceiclcs  irhicb  open 
one  into  the  other,  forming  a  jmrlitioned  anfractuous  cuvity  in  the  midille 
Inyer  of  the  rete  mucosum.  In  this  cavity  are  found  ejiidermie  cells  with 
several  nuclei,  besides  wnnderiiig  cells  from  the  veitMN  havîn;;  the  char- 
acters of  white  blond  coqiuscles.  In  time,  tJic  cellular  elements  uiwlcr^ 
fatty  degeneration,  and  sometimes  the  Bnid  of  the  vesicle,  which  at  first 
is  clear,  becomes  yellow  and  opaijue.  This  transformation  is  very  dis- 
tinct in  rheumatic  miliary  eniptiona.  in  sudamiua,  and  in  the  vesicles  of 
TariceHa,  whieb  are  only  diftcrt-nt  varieties  of  vesicles. 

In  eczema,  this  transformation  of  the  very  small  ami  numerous  vesicles 
does  not  tate  place  before  they  break  and  discbarge  a  serous  fluid.  But 
if  the  exuded  Hnid  is  kept  in  eoniaet  with  the  skin,  by  enveloping  the 
latter  in  an  impermeable  cloth,  iu  about  twenty-four  hours  the  fluid  hat 
all  the  characters  of  pus.  The  lesions  prwluii-d  in  tlie  dcnAa  by  cbrutik 
ccKcniu  do  not  dili'er  from  those  following  chronic  dermatitis. 


l*l'BTtil.B3. — The  proccus  of  the  formation  of  pustules  has  a  very  cl 
analojcj,-  with  the  preceding.     The  evolution  of  the  pustules  of  varicda 
may  be  tjiken  as  a  type.     (I*'ig.  352.) 

A  pnpulc  of  variola,  examined  on  Ihc  fourth  day,  presents  Ute  clinrfec-

nnd  the  li^iiue  of  the  denn  aldicked  with  dilTused  îiiflaDiitmtion  ischai^d 
iuto  euihrjroriic  tissue.  With  the  ptislitlc  there  is»  oiore  or  less eoiD|)lete

permauent  inaHc,  while  u  llUler  uud  vi-sicio  luarc  no  trace.

very  titie  filaments  arc  seen  reaching  from  the  derma  to  the  e|)iderait! 
layer,  which  forma  the  roof  of  tlie  pustule.  From  the  top  of  each  denuded 
papilla,  projecting  from  the  floor  of  the  pustule,  arise  a  number  of  these 
oljuiiente.  which  at  firat  scorn  to  bo  coniinnous  with  the  fihrils  of  the  p«> 
Mllary  connective  tissue.  This  is,  however,  not  tlic  C4i«i,  for  it  is  known 
(Ranriei')  that  tlio  fundamental  substance  of  the  connective  tissue  ter- 
minates bcncatli  the  rctc  inueoeum  l>y  a  series  of  Mrratious  destined  l« 
receive  the  procesxea  of  the  sfunous  cells,  and  the  <term  does  not  send  iuto 
the  (.'pidenuis  any  fibrillar  prolongntiotu.  The  network  which  haa  just 
Iwen  <lc«cribeil  m  always  existing,  possibly  repre*ent«  the  cement  sub- 
Stance  (Kittsiibslunn)  heiwv«n  the  cdU  uf  the  rote  tnucojutn.  It  h«, 
contrary  to  tbc  opinion  of  some  writers,  no  part  in  the  umbiiicaliou  of 
the  pustule.  When  this  umbilication  exists,  it  is  caused  by  the  centre  of 
the  elevation  being  riddled  by  a  partitioned  cavity,  while  the  postule 
contimies  to  increase  at  the  periphery  (Fcorster).  The  cpidcmtic  cells 
at  the  periphery  being  swollen,  there  results  a  comiMtnitive  prwjc«tiou  ta 
the  form  of  a  circular  élévation. 

The  hain  and  glands  take  no  part  in  the  formation  of  pustule»  m 
variola  (Charcot).  Cicatrices  exi*t  only  in  the  variety  of  piisUdes  termed 
diphtheritic,  and  in  which  there  is  produced  a  true  necro«i»  of  tiie  derm, 
consecutive  to  the  in&ttraUon  of  fibrin  or  of  pu.t  into  the  meshes  of  ibo 
latter.  I'his  occurs  iu  confluent  variola.  The  simple  [lustule*,  thom;  gf 
iinpcti>:o,  for  example,  do  not  teafe  any  trace  of  Uieir  existence,  sînvc 
the  derm  has  not  sphacelated  beneath  them. 

Tl'DBHCULKS. — When  a  limited  chronic  inflammation  extends  iuto  the 
deep  portions  of  the  derm,  the  latter  first  returns  to  the  embryonic  state, 
then  elevates  tlie  superficial  parts  of  the  skin  and  forms  a  nodide,  which 
to  the  touch  htis  the  feel  of  »  driji  nrcHmtcriied  iTnlumtio».  In  dcr* 
mstology  thi.'t  is  termed  a  tubercule.  Its  stmctitre  has  been  described 
under  the  aflectîons  in  which  it  is  developed — ri/fhiU»,  «crqfula,  ffltmi- 
er»,  etc.  A  tubercule,  whatever  may  be  its  nature,  nay  ulcerate,  may 
ciiange  into  a  fibrous  nodule,  or  may  become  gangrenous,  according  to  tbe 
systemic  conditions  which  influence  its  growth,  and  cause  n  tendeucy  to 
reparation,  to  new  fortnalions,  or  to  ganjfreae.

the  type.  PifTuse  suppuration  of  the  skin  almost  never  occurs.  The 
type  or  «uppttritive  Jerotatitit  is  the  pustuloo»  inflammation  of  variola, 
which  occur»  at  more  or  leag  dintanl  points.  On  the  other  hand,  hi/pfr- 
pfa*tic  inflammation  A  of  ilie  skin  are  fréquent,  as  are  also  the  ilrifrnrr.i- 
the  injlamni'itionii,  and  they  occur  more  fre.|Uently  in  the  general  dis- 
eased, of  which  they  arc  the  local  raAnifcstations,  and  from  which  tliey 
receive  a  peculiar  impress. 

1.  HïPKWi-ASTic  Imxammatioxs;  Formativs  Dbbmatitis.  — It  is 
known  that  prolonged  irritation  of  the  derma  ends  in  the  pro>tuction  of 
a  hyjiertrophic  dermatitis,  and  iti  new  formations  approximating  lumon 
(iliH'used  papillomata  of  the  skin).  This  tendency  to  the  formation  of 
fibrous  tissue  is  never  more  marked  than  in  syphilitic  ïuâjunmatious  of 
the  skin,  nud  the  latter  may  be  Considered  m  the  beat  typc«  of  formative 
dcriim  litis. 

a.  Sj/iihililiiT  J'tifiuli-. — At  the  bej^inning  it  cannot  be  dislincoiahed 
from  a  simple  intlummation.  Itut  very  »oon  the  papillie  of  the  skin  ar« 
hypertrophied,  the  derma  is  tliickened,  and  there  is  a  new  formation  of 
connective-tissue  Bbres  and  elastic  network  beneath  tlie  papillary  emi- 
nence. The  suhcutaneous  adipose  tissue  becomes  embryonie  (Neumann), 
and  the  sudorific  ^Innds  are  inflamed.  In  very  old  syphilitic  papales 
vhieh  are  about  disappearing,  the  congestive  inGltration  of  the  dertna 
by  white  corpuscles  no  longer  exist?,  and  the  lesion  consists  only  in  an 
enlargement  of  the  papilliv  and  a  greater  thickness  of  fibrous  tissue. 

h.  Stfphilitie  Tubfretilr. — In  this  lesion,  frequently  eoiifoutkded  »ilh 


cutaneous  gumma,  the  tendency  of  the  syphilitic  inflammation  to  prodoee 
fibrous  tissue  is  still  more  evident.     The  syphilitic  Ë'  '

in  the  derma  ;  all  around  it  there  exist  Buiall  collections  oF  embryonic 
cells  between  the  separated  connective-tissue  fasciculi.  In  the  middle 
of  the  nodule  the  ncwlj  formed  tissue  is  very  similar  to  that  of  tendona, 
while  at  the  periphery  it  resembles  a  sarcoma,  except  in  oontaiuing 
Qumeroue  elastic  fibres.  The  specific  inflammation  occasions,  in  the  prox- 
imity of  the  tubercule,  a  very  marked  endarteritis,  which  causes  the  calibre 
of  the  vessels  to  be  considerably  narrowed.  This  narrowing  probably  has 
some  influence  in  the  production  of  ulcers.  The  tubercule  deprived 
of  vessels  at  its  centre,  and  very  poorly  supplied  at  its  periphery,  rapidly 
undergoes  a  slow  molecular  softening,  and  opens  externally  as  an  abscess. 
The  loss  of  substance  is  filled  up  with  granulation  tissue,  and  cicatriza- 
tion takes  place  by  the  usual  process. 

e.  False  Keloid. — Sometimes  localized  pustular  inflammations  of  the 
skin  occasion  a  secondary  chronic  formative  inflammation.  Consecutively 
to  variola,  to  the  application  of  irritating  ointments  (Croton  oil,  tartar 
emetic),  or  to  the  existence  of  pustular  syphilides,  true  fibromata  of  the 
skin,  which  have  the  homogeneous  appearance  of  a  tendon,  may  be  de- 
veloped. Surrounding  the  nodule  formed  of  closely  packed  rascicnli, 
between  which  are  numerous  clastic  fibres  or  elastic  plates  analogous  to 
those  developed  so  abundantly  in  fibrous  carcinoma,  there  is  a  zone  of 
embryonic  tissue.  Tliis  tissue  is  especially  evident  in  the  papillie,  which 
are  enlarged,  consist  of  embryonic  tissue,  and  contain  embryonic  vessels. 
In  the  interior  of  false  keloid  the  veins  are  frequently  dilated  into  large 
irregular  sinuses.  The  epidermic  layers  are  thin,  and  des<iuamation  is 
active  upon  the  surface  of  tlie  fibrous  nodule.  True  or  spontaneous 
keloids,  which  are  true  fibromata  of  the  skin,  do  not  essentially  differ 
anatomically  from  false  keloids. 

2.  Deqexerative  Inflammations  ;  Specific  Ui/iers  op  the  Skis, 
— In  inflammations  of  the  skin  due  to  tuberculosis,  to  glanders,  to  leprosy, 
and  to  scrofula,  the  newly  formed  tissues  die  anil  doi;cnerat«  in  several 
ways  ;  usually  they  undergo  easeous  (tuberculosis,  scrofula)  degeneration, 
or  there  is  produced  a  true  gangrene  (glanders,  etc.). 

a.  Tuherruhiis  Ulcers  of  the  iSkin  are  a  very  unfrequent  manifesta- 
tion of  tuberculosis.  When  they  do  occur,  tiiey  are  most  frequently 
accompanied  with  tuberculous  granulations  in  the  skin,  in  the  subcuta- 
neous tissue,  and  between  the  primarv  fasciculi  of  the  muscular  layers 
immediately  subjacent  to  the  integument.  The  evolution  of  these 
granules  is  the  Siime  as  tuberculous  granulations  in  the  tongue  (see  page 
454),  Around  these  granules  the  denna  and  subcutaneous  tissue  are  in- 
invaded  by  a  diffuse  inflammation.  The  muscles  near  the  skin  (it  is 
ordinarily  upon  the  face  or  about  the  anus  that  these  tumors  are  ob- 
served) are  the  seat  of  a  destructive  inflammation  ;  tiie  contractile  sub- 
stance disappears,  while  the  nuclei  divide,  multiply,  and  fill  the  sarco- 
lemma.  In  a  short  time  the  embryonic  cells,  which  have  accumulated 
in  the  different  tissues,  undergo  fatty  degeneration,  and  form  caseous 
points.  The  vessels  are  obstructed  by  clots  which  become  granular,  and, 
aa  a  consequence  of  the  disintegration  of  the  parts  which  they  supply 
with  blood,  an  ulcer  is  produced. 

This  uleer  does  not  granulate  ;  it  rests  upon  a  thickened,  degenerated

nlceratiflu  is  probably  caused  by  the  1«eal  unwinta  and  the  présence  of 
nutnoroiiH  interstitial  heinorrha;,;ie  foci .  'I'he  ulcer  which  result»  is  atonic, 
and  even  gangrenous,  on  account  of  the  iTiti-a-<lennic  hemorriiagea.  Sur- 
rounding the  lesion  are  seen  numerous  lymphatic  cords,  which  are 
somewhat  characteristic  of  farcy  granules. 

e,  Leprou*  Dermatiti»;  Cutamou*  TtthemUe  ^  Ltprogy. —  By 
cxaininiug  »  recent  tubercule  of  leprosy  after  teasing,  it  is  found  that  the 
greater  part  is  fonned  of  flat  connective- tisane  cells  having  several  nuclei, 
rei<«in)>ling  {riant  cells.  Upon  section,  it  is  seen  that  the  fuiidamenlal 
subiftancc  of  the  conneutivc  tissue  is  destroyed,  while  the  endothelial 
oelU  are  multiplied.  The  appeanince  of  the  lubereule  of  leprosy  is  tlwn 
very  little  different  from  a  fascicular  sarcoma.  In  a  word,  in  tliis  sUge 
Uiere  is  observed  a  formative  irritation  especially  affecting  tlie  flat  cells 
of  the  connective  liiuue. 

vVl  the  same  time,  surrounding  the  tubereute  of  leprosy,  tliem  ftxiala  • 
diOiiae  inflammation  of  the  de nna,  which  extends  in  depth  hy  rows  of 
embryonic  cells  rtmuing  towards  tiie  suhculaneoas  adipise  tissue.  Tie 
acenmidatiou  of  embryonic  cells,  as  in  every  cbroiùe  dermatitis,  occurs  at 
fir^t  an>uiid  tlie  vessels  whew  walU  are  thickened  by  endarteritis  or 
endnplilebitis.  The  vessels,  however,  ordinarily  do  not  l>ccoine  emhryoBie 
as  in  the  E-arcontata. 

As  a  consequence  of  tbe  inflamination  of  the  internal  coat  of  the 


DYSTROPHIBB    OF    THE    8KIK.  7S9 

vessels,  there  occurs  in  time  an  ischEemia  of  the  leprous  tubercule,  the 
capillary  network  of  which  no  longer  communicatcs  with  that  of  the 
neighboring  parts.  The  leprous  neoplasm  now  undergoes  granulo- 
f&tty  degeneration  from  the  centre  to  the  periphery,  and  may  ulcerate 
like  an  atheromatous  abscess.  The  hair  follicles  in  the  neighborhood  of 
the  lesion  atrophy.  The  sebaceous  glands,  at  first  irritated  by  the  chronic 
inSammation,  are  gradually  destroyed.  The  sudorific  glands  also  disap- 
pear, the  destruction  beginning  in  the  excretory  canals  and  e:ctending 
downwards  ;  this  accounts  for  the  dryness  of  the  integument  in  a  person 
affected  with  leprosy.  Finally,  the  epidermis  is  very  thin  and  smooth 
around  the  tubercule;  it  freely  desquamates,  even  from  the  heginniog, 
for  leprosy  commences  in  the  skin  as  a  macula.  Beneath  this  spot  the 
derma  is  inflamed  and  ita  vessels  are  dilated,  causing  permanent  hyper- 
semi  a. 

The  nerves  are  primarily  attacked  by  interstitial  inflammation  (Steud- 
ner}.  The  tactile  corpuscles  disappear,  or  at  least  they  cannot  be  found 
(Lamblin)  in  the  finger  pulpa,  where  they  are  very  numerous  in  the 
nonnal  state.  These  changes  connect  leprosy  with  dystrophic  aflectiona 
of  the  skin  which  have  their  origin  in  nerve  lesions,  and  account  for 
the  anaesthesia  constantly  present  in  this  disease. 


Sect.  Vtl.— Systropliies  of  the  6kin. 

A.  Tropuic  Disturbances  consécutive  to  Lesions  of  the  Nervous 
System. — It  is  known  that  the  nervous  system  exercises  a  direct  influence 
over  the  nutrition  of  the  anatomical  elements.  When  the  tissues  are 
removed  from  this  influence,  their  elements  actively  increase,  as  if  from 
an  individual  impulse  (see  page  75,  an  experiment  of  8chroeder  van  der 
Kolk).  There  thus  result  aberrant  formations,  which  generally  have 
the  type  of  inflammatory  neoplasms  of  slow  growth. 

Cutaneous  oedema  very  often  is  seen  in  the  skin  of  paralyzed  limbs, 
especially  of  the  arms.  The  continuation  of  tlie  œdema  frequently  ex- 
cites a  hypertrophic  dermatitis,  when  the  skin  becomes  warty.  From 
time  to  time,  there  are  also  often  seen  upon  the  uedematous  integument 
active  congestions  (erythema),  which  usually  terminate  by  resolution, 
but  sometimes  are  tlie  origin  of  gangrenous  spots. 

The  influence  of  nervous  lesions  upon  the  [lutrition  of  the  skin  is  well 
shown  by  the  patliological  histology  oî  pin-f or  tiling  ulcer  of  the  foot.  In 
this  lesion  it  is  found  that  the  nerves  of  the  skin  in  the  proximity  of  the 
ulcer  are  the  seat  of  a  degeneration  analogous  to  that  met  with  in  the 
inferior  end  of  a  divided  nerve.  The  medullary  substance  breaks  up 
into  small  drops,  the  nuclei  of  the  interannular  segments  divide  and 
cause  a  moniliform  appearance  of  the  nerve  fibres.  The  axis  cylinder 
has  been  destroyed,  etc.  Associated  with  the  nerve  lesions  there  is 
observed  around  the  ulcer  a  zone  of  aniesthesia  and  of  chronic  inflamma- 
tion. The  cutaneous  papillae  of  the  derma  have  become  gigantic  in  size, 
resembling  the  subungual  papillae.  They  are  long  and  slender,  and 
contain  vessels,  and,  if  they  are  not  entirely  deprived  of  nerves,  they  at 
least  contain  but  very  few.     The  tactile  corpuscles  have  generally  disap-

is  not  clearly  understood.  The  coloration  is  sometimes  bluish.  The  pig- 
mentation of  the  rete  mucosum  is  found  to  be  more  intense. 

In  Addison's  disease  the  skin  ia  not  only  pigmented  in  the  deep  layers 
of  the  rete  mueosnm,  but  frequently  also  in  the  derma.  A  transverse 
section  of  the  skin  in  Addison's  disease,  shows  not  only  the  cylindrical 
cells  of  the  rete  mucosum  which  cover  the  papillae  loaded  with  pigment, 
as  in  the  negro,  but  often  dark  pigment  ia  also  accumulated  along  the 
vessels  of  the  papillae,  and  in  Ûie  fixed  cells  of  the  connective  Ussue. 
This  is  also  observed  in  certain  pigmentations  from  external  causes. 

Pigmentation  produced  by  sulphate  of  lead  is  due  to  a  metallic  de- 
posit, not  in  the  cells  of  the  rete  mucosum,  which  are  never  colored,  but 
in  the  fixed  connective-tissue  cells.  The  pigmentation  is  so  abundant 
in  the  bands  of  connective  tissue  which  accompany  the  vascular  tufts  of 
the  papillae,  that  it  has  been  believed  that  the  sulphate  of  lead  is  contained 
in  the  vessels.  There  is  also  found  in  the  meshes  of  the  derma  a  number 
of  wandering  cells  loaded  with  dark  granules  of  sulphate  of  lead  (Re- 
naut),  and  which  probably  play  an  important  part  in  the  process  of  pig- 
mentation by  transporting  the  colored  granules. 


Sect.  Vin.— Pansitio  A&ctioni  of  the  Skin. 
Parasites  of  the  skin  in  man  are  of  two  orders,  animal  and  vegetable. 

A.  Animal  Parasites  op  the  Skin  op  Mas. — The  true  parasites  of 
the  skin  are  those  which  are  bom  and  developed,  live  and  die  upon  the 
surface  or  in  the  substance  of  the  cutaneous  membrane.  The  moat  im- 
portant arc  arariia  sfabiei  and  acarvB  foUiculnrnm. 

a.  The  acaru»  icabiei  (^sarcoptes  hominig)  occasions  in  the  skin  an 
eruption,  with  the  characteriiitic  burrows  in  which  the  eggs  are  deposited. 
The  female  acarus  is  most  frequently  found.  It  is  visible  to  the  unaided 
eye,  measuring  about  0.33  mm.  in  its  greatest  diameter.  Under  the  mi- 
croscope its  integument  appears  striated  by  numerous  parallel  lines;  the 
abdomen  presents  conical  prominences,  each  terminating  in  long  fine  hairs. 
At  each  side  of  the  head  or  rostrum  there  are  found  two  pairs  of  limbs 
provided  with  suckers.  At  the  posterior  portion  are  seen  two  other 
pairs  without  suckers  and  terminating  in  long  hairs.  The  insertions 
of  the  limbs  arc  upon  the  ventral  surface.  The  head  consista  of  two 
cutting  mandibles  formed  like  scissors,  behind  which  are  two  feelers 
ending  in  bristles.  Posterior  to  the  head  is  found  the  digestive  canal 
whose  terminal  opening  is  in  the  posterior  region  of  the  animal.  The 
ovary  is  distinct  and  generally  distended  with  eggs.  The  respiratory 
apparatus  appears  to  be  rudimentary  or  absent.  They  live  for  a  very 
long  time  without  air,  either  in  the  substance  of  the  skin,  or  submerged 
in  petroleum  (Iturchard).  According  to  Bourguignon  they  respire  only 
by  swallowing  the  air,  the  cesophagus  carrying  it  into  a  number  of

and  auricle  which  have  become  aeneous. 

B.  Vegetable  Parasites  of  the  Skin  op  Man. — Upon  examination 
of  an  uncolorcd  aection  of  normal  skin,  previously  treated  with  ether 
and  subsequently  mounted  in  Canada  balsam,  there  are  seen  in  places 
where  the  epidermis  is  thick  a  number  of  vegetable  spores  contained  in 
the  corneous  layers.  These  aporea  vary  in  size  and  shape.  They  do 
not  correspond  to  any  determined  cutaneous  affection;  the  probable 
multiple  vegetable  species  to  which  they  belong  have  not  yet  been 
accurately  defined.  When  an  inflammation  occurs  in  the  skin,  and 
especially  when  the  latter  has  been  covered  by  a  poultice,  the  number 
of  microscopic  plants  is  increased.  If  a  vesicle  or  bulla  is  formed,  the 
fluid  in  it  frequently  contains  spores.  A  number  of  pathological  anato- 
mists, especially  Orth  (of  Berne),  believe  that  these  organisms  play  an 
important  part  in  the  development  of  certain  diseases  of  the  skin,  erysipe- 
las, for  example.  But  the  true  parasites  of  the  skin,  that  is,  those  which 
accompany  or  occasion  cutaneous  affections,  never  exist  primarily  in  the 
epidermis  of  the  normal  skin,  and  they  cause  in  the  diseased  skin 
characteristic  elementary  lesions. 

a.  Vegttahh  Parasite  of  Tinea  Favosa  {Acliorlon  SchoetileiHiC). — 
Discovered  in  1839  by  Schœnlein  in  the  scabs  of  favus,  afterwards  by 
Gmby  and  Wedl,  this  parasite  was  6r8t  inoculated  with  success  upon  the 
akin  of  the  arm  by  Remak. 

By  removing  a  small  piece  of  the  yellow  fungus  of  favus,  and  placing 
it  in  a  solution  of  ammonia,  it  soon  breaks  up,  when  the  parasite  may  be 
isolated.  By  the  addition  of  a  few  drops  of  solution  of  iodine  in  water 
containing  ioflide  of  potassium,  the  fungus  is  colored  red-brown,  and  ita 
structure  can  be  seen.  It  is  composed  of  roundish  spores,  isolated  or 
united  in  the  form  of  chains.  These  chains  of  spores  usually  terminate 
the  filaments  of  the  mycelium  (or  tlmlus).  At  the  free  extremity  of  the 
Utter  they  are  at  first  spherical,  afterwards  becoming  slightly  elongated, 
ao  that  the  filament  is  formed  by  the  union  of  short  joints.  The  filaments 
of  the  mycelium  are  composed  of  elongated,  distinct,  dotted,  dichotom- 
onsly  ramifying,  firmly  united  joints.  The  spores  forming  chains  are 
very  frail,  and  arc  considered  aa  a  portion  of  the  plant  in  the  process  of 
germination.      {Fig.  â.W.) 

Upon  a  vertical  section  of  the  skin  through  a  sjiot  covered  by  a  favus 
fungus,  at  the  surface  fonncd  by  the  fungus,  the  epidermic  layers  are  seen 
filled  with  spores  which  are  scattered  between  the  corneous  cells.  With 
the  spores  are  always  scon  micrococci  and  bacteria,  besides  small  drops 
of  fat.  The  accumulation  of  these  foreign  elements  causes  a  prominence 
and  a  peripheral  swelling  of  the  fungus.  The  deiireasod  centre  is  usually 
occupied  by  one  or  more  diseased  hairs  ;  here  ia  where  the  evolution  of 
the  fungus  takes  place  and  where  recovery  begins.  The  affection  heals 
at  the  centre  wliiie  at  the  periphery  it  extends  in  a  circular  manner. 

In  favus  fungi  of  considerable  extent,  the  invasion  of  the  parasite 
is  not  limited  to  the  epidermic  layers.     The  mycelium  penetrates  per-

A  number  are  cylindric»!  in  shape,  and  placed  end  to  end.  Neumann, 
m  opposition  to  the  assertion  of  Oh.  Robin,  has  pointed  out  in  this  para- 
site the  presence  of  a  ramifying  mycelium. 

The  parasite  is  ordinarily  found  in  the  lamellse  of  the  epidermis  by 
scraping  the  surface  of  a  tinea  cireioata  and  macerating  it  in  a  solutJon 
of  potassa  or  ammonia.  The  growth  of  the  parasite  in  the  hair  differs 
little  from  that  of  favus.  The  spores  are  usually  abundant  at  the  root 
of  the  hair,  growing  from  below  upwards  between  the  longitudinal  fibres 
of  its  cuticle.  The  epidermic  lamtniB  of  the  shaft  of  the  hair  are  some- 
what separated,  in  consequence  of  which  the  bair  becomes  brittle  and 
breaks.  Around  the  hair  in  the  inner  epidermic  sheath  the  parasite 
accumulates  and  causes  an  abundant  formation  of  epidermic  laminie  sepa- 
rated from  one  another  by  rows  of  spores.  There  thus  is  formed  a  kind 
of  white  collar  around  the  hair,  projecting  above  the  point  where  it 
emerges  from  the  skin.  This  ensheathing  of  the  hair  is  of  great  diag- 
nosUc  importance,  but  it  is  seen  in  other  afi"BCtion8  besides  parasitic. 
Microscopic  examination  alone  can  fix  the  diagnosis  in  doubtful  cases.

A  number  of  dermatologists,  and  among  them  Ilebra,  consider  the 
Tri'iophi/ton  tonsuraim  as  a  simple  variety  of  the  Anhorion  Schœnhinii. 
But  Kobner,  in  cultivating  the  parasite,  has  reproduced  it  indefinitely, 
with  its  specific  characters.  Ilallier  considers  it  identical  with  the  Peni-

Uon  of  it.  The  seat  of  the  parasite  is  in  the  corneous  layer  of  the 
epidennia,  upon  the  surface  of  the  epidermic  cells,  and  in  their  inter- 
stices. It  does  not  penetrate  into  the  hair  follicle,  and  is  only  accidentally 
met  with  upon  the  hairs  (tig.  359). 

It  consists  solely  of  spherical  spores  without  any  trace  of  mycelium. 
The  largest  of  the  spores  measure  from  .004  mm,  to  .005  mm.  in  diame- 
ter, and  present  a  double  contour;  others  are  only  .002  mm.  in  diameter, 
and  have  a  single  contour;  and,  finally,  spores  are  seen  loss  than  .002 
mm.  in  diameter.  The  parasite  would  then  seem  to  multiply  by  bud- 
ding (fig.  360).

Griiby  affirmed  that  the  mirrotporon  Audouini  is  first  developed  upon 
the  surface  of  the  hair,  at  a  distance  of  one  to  two  millimetres  from  the 
surface  of  the  8kin,  and  that  it  sends  ramifying  filaments  into  the  tissue 
of  the  hair.     Malasscz  has  not  confirmed  any  of  these  assertions. 

f.  Vef/etafile  Faraxite  of  Pitifriati»  Capitis  simplex. — This  parasite 
was  discovered  in  1ST4,  by  Malasse;f,  in  the  ejiidermic  pellicles  of  the 
hair  of  tlic  scalp. 

Its  seat  is  in  the  corneous  layers  of  the  epidermis,  between  the  cells. 
It  penetrates  into  the  hair  follick's,  but  only  near  the  point  of  emergence 
and  a  little  below  it.  It  does  not  de.iccnd  beyond  the  orifice  of  the  seba- 
ceous glands  connected  with  the  hair.  It  is  freciuently  very  abundant, 
although  it  has  escapd!  the  investigation.'*  of  dermatologists  until  recently. 

This  parasite  consists  only  of  spores,  gcneriiHy  elongated  and  hud- 
ding  ;  the  largest  have  a  length  of  .004  mm  to  .00.5  mm.  and  a  width  of 
.00:i  mm,  to  .002.">  mm.     The  smallest  are  only  .002  mm.  long. 

From  the  investigations  of  Malas^ez  this  paraeito  appears  to  play  an 
imjiortant  part  in  the  production  of  the  laraelliB  of  pityriasis.  In  this 
cutaneous  disease  the  alopecia  is  caused  by  two  processes  :  first,  the  me-

APPENDIX. 


PRESERVATION  AND  HARDENING  OF  TISSUES. 

[For  the  benefit  of  those  who  are  not  practical  microscopista,  and  who 
conaequentiy  are  often  obliged  to  refer  !nterestin<r  and  valuable  patho- 
logical specimena  to  some  physician  in  whose  skill  and  knowledge  they 
have  confidence,  as  well  as  in  the  interest  of  thoae  who  may  be  requested 
to  examine  and  report  upon  diseased  tissue,  this  appendix  is  added. 
Time  and  time  again  pathologists  are  called  upon  and  expected  to  deci- 
pher the  evidences  and  nature  of  morbid  processes  in  tissues  half  rotten 
or  so  far  decomposed  that  it  is  utterly  impossible,  even  to  the  keenest 
and  moat  practised  eye,  to  recognize  with  certainty  any  but  the  grossest 
elementary  lesions.  Methods  of  preserving  tissues  and  organs  in  the 
gross  for  naked  eye  inspection,  with  which  the  general  practitioner  of 
medicine  has  been  so  long  familiar,  are,  as  a  rule,  worse  than  useless, 
when  employed  in  the  preparation  of  tissues  for  examination  under  the 
microscope.  Much  of  the  destruction  of  the  minute  traces  of  disease,  in 
specimens  obtained  from  post-mortem  examinations,  is  without  remedy, 
for  fretjuently  the  autopsy  cannot  be  made  within  twenty-four  hours  after 
death,  and  after  that  lapse  of  time  cadaverous  decomposition  has  wrought 
considerable  change  in  many  of  the  most  delicate  tissues,  particularly  in 
the  nervous  system  and  the  mucous  membranes.  It  is  obvious  that  no 
method  of  preparation  can  repair  the  damage  already  done  by  decompo- 
sition ;  hence  the  necessity  of  performing  the  aut-opsy  at  the  earliest 
pmctjcable  moment,  and  the  demand  for  the  preservation  of  the  speci- 
mens obtained  without  delay. 

Those  tiasuea  which  are  secured  during  the  life  of  the  patient  by  the 
interference  of  the  surgeon  or  otherwise,  fihould  be  at  once  submitted  to 
examination  in  the  recent  state  or  be  immeiJiateJy  placed  in  a  proper  pre- 
servative agent  for  future  study.  The  old  custom  of  macerating  or  wash- 
ing the  tissue  for  the  removal  of  blood,  etc.,  should  be  avoided.  In  re- 
moving the  piece  great  care  should  be  exercised  lest  pressure  of  any 
kind  he  exerted.  This  caution  is  always  important,  but  it  should  be 
especially  regarded  when  handling  any  part  of  the  nervous  system  or 
digestive  appiiratus.  In  histologiciil  examinations  it  is  most  important  to 
study  the  relations  of  the  elements  as  well  as  their  individual  conditions. 
For  this,  extremely  thin  sections  must  be  made,  and  subsequently  pre- 
pared for  the  microscope.  Hence  it  is  necessary  that  the  tissues  to  be  cut 
should  be  conveniently  hard  and  cohesive.  Soft  parts  must  be  hardened, 
and  bony  or  calcareous  substances  must  be  softened.  There  are  various 
methods  of  securing  these  essential  conditions.     It  is  not  our  purpose

inteli^iblo  interprétation  of  llieir  nature.  The  folloving  Bugg«ations  are 
imjtorUint  to  oha«rve  :— 

■V/îK  «/  thf  Piei-t  to  he.  Kr'tmined. — It  ÎB  es*enlial  that  ei-ery  part  flf 
tlie  tissue  should  be  >|wiekly  reachc<l  and  aclf^l  upon  by  the  a^cui; 
this  is  tlic  more  essential  the  jn^^ater  the  delicacy  of  thv  tissue.  I'irccs 
submitted  to  the  action  of  the  liarileDin<^  and  preservin;*  a^cnt,  as  n  nilr, 
should  not  much  exceed  half  a  cubic  inch.  Nervotu^  Miibstance  ami  other 
delicate  tiMtues  «ho\ild  have  «nailer  dimcnuions.  When  the  whole  or  a 
conàderahlo  part  of  an  orgnu  ia  to  be  examined,  the  relatiuna  of  tlte 
difTcreiit  pnrt^  titioiild  not  be  entirely  tiacriRced  to  the  demand  for  small 
i.iolated  pieces,  but  the  tissue  should  be  inci.ied  in  varioiu  direetionii  in 
such  a  manner  as  to  allow  the  fluid  to  {jnickly  reach  every  cubic  inch  of 
it.  The  cuttin;;;  iii;itru[Dcnt  used  for  this  purpose  should  hare  a  keen 
edge,  so  that  the  slash  can  be  made  with  a  minimum  of  pre«8ure.  Hie 
spinal  marm>w  should  be  cut  across  at  Intenals  of  half  an  inch. 

Ilffative  i'rcpnrtinn»  of  the  Ti'mhc  ami  the  Fluid. — Five  or  six  ounces 
of  thi-  fluid  arc  iMually  roi|iii5itc  for  every  cubic  inch  of  tÎKSUC  to  W 
pre]jiart'().  Kreahiieits  of  the  fluid  is  alM>  of  great  importance.  A>>  a 
rule  the  fluid  should  be  changed  everv  twenty-four  hours  during  llie  Brst 
three  or  four  davs.  The  liâsue  alioufd  be  suspended  in  the  midst  of  Uie 
fluid  by  a  threat!  instead  of  being  allowed  to  rest  upn  the  bottom  of  tlie 
vessel. 

'riie  choice  of  the  fluids  used  for  hardening  and  preserving  should  vanr 
somewhat  according  to  the  nature  and  conditinn  of  the  tissue  and  accont- 
iDg  to  the  methods  to  be  folloned  by  the  hislologist  subsequent  to  the 
making  of  sections.  Those  llnids  most  genenilly  eflicieut  arc  Dame<l 
below. 

it/U//er*«  Fluid.— Water,  100  parU;  biohromatc  of  poUBw,  2  pnrts; 
sulphate  of  soda,  1  jiftrt. 

liithromatf  of  Aintimnia. — Thia  agent  may  be  used  in  the  following 
BtrengtJi:  bichromate  of  ammonia,  ^—'>  parts;  water,  100  parts. 

Alcohol. — Alcohol,  ilie  oldest  and  one  of  llie  most  generally  lueful 
hardening  agentt),  should  best  be  used  in  die  following  manner:^ 

The  fimt  solution  should  be  00  per  cent,  in  strength. 

The  second  solution  should  be  to  per  cent,  in  strength. 

The  third  should  be  the  strongest  alcohol. 

The  fir^t  solution  should  be  u^ed  in  the  first  24  or  4â  boars  ;  the 
second  for  the  next  4è  hours,  when  llie  strong  alcohol  may  be  snbstituicd. 

Chromii-  Afid. — This  reagent  needs  t<i  bo  very  carefully  used.     Thfl 
«olution  should  be  made  by  weight  and  nieasureoivnt,  never  by  estimatia 
from  the  depth  of  color,  otherwine  it  becomes  u  very  troublesome 
often  destructive  fluid.     The  »trei)glh  of  ihis  soUiiion  «lioaM  be  2 — 5 


APPENDIX.  T51 

parts  of  chromic  acid  to  1000  parts  of  water,  commencing  vrith  the  weaker 
and  ending  with  a  stronger  proportion.  This  reagent  makes  the  tissues 
too  brittle  if  they  are  left  too  long  exposed  to  its  action.  It  is  particu- 
larly valuable  for  the  nervous  syatcm  and  extremely  delicate  tissues. 

I'hrie  Add. — It  should  be  used  in  saturated  solutions.  The  crystals 
are  not  very  soluble.  Hence  solutions  should  be  made  with  warm  water, 
or  if  made  with  cold  water  the  sediment  uliouhl  be  well  stirred  at  intervals 
during  two  or  three  days.  With  this  fluid  the  tUaues  are  better  placed 
at  the  bottom  of  the  vessel. 

Timi-  Ki'iimri'.d for  Ifirdenin;/. — Most  of  the  tissues  are  hardened  lu 
a  few  days  when  placed  in  alcohol  or  in  picric  acid.  The  latter  fre- 
qucTitly  makes  the  tissue  sufficiently  firm  for  rough  sections  within  twenty 
hours. 

Nerve  tissue,  especially  that  of  the  centres,  the  hrain,  and  spinal 
marrow,  rciinires  much  longer  exposure  to  the  action  of  the  roa;;ent, 
The  brain  or  spinal  cord  must  be  immersed  in  chromic  acid,  MilUer's 
fluid,  or  bichromate  of  ammonia  five  or  six  weeks  before  it  is  sufficiently 
firm  and  tough. 

Trfutiiii-nf  of  Tifnue»  after  Hardenimj. — When  the  specimen  lias 
become  sufficiently  firm,  it  should  bo  removed  from  the  hardening  agent 
if  chromic  acid,  picric  acid,  bichromate  of  ammonia,  or  Miiller's  has  been 
used,  should  be  thoroughly  soaked  in  water  until  tbe  tissue  ceases  to 
tinge  the  water,  and  finally  placed  in  alcohol  of  8.5  per  cent,  for  indefi- 
nite keeping. 

Deealn/i/inff  Ajient». — Both  saturated  picric  acid  and  chromic  acid, 
in  the  strength  of  '1 — -i  parts  to  lUOO,  possess  the  property  of  dissolving 
the  cakareoHs  salts  in  hones  or  other  tissues.  Where  the  piece  to  be 
acted  upon  is  very  small  and  the  fiuid  is  in  large  amoinit,  the  acid  should 
be  often  renewed. 

The  portion  of  tissue  to  be  softened  should  not  exceed  a  (juarter  of  a 
cubic  inch,  and  the  fluid  should  not  be  less  than  five  or  six  fluid  ounces. 
These  agents  harden  the  elements  at  the  same  time  that  they  dissolve  the 
lime  Balte.]
