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-
round themselves by a membrane to form the nucleus ; the nucleus now
acts upon the surrounding blastema, new granules appear and arc soon
surrounded with a cellular membrane, when at last wo have formed the
perfect element termed a cell.

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

f^iilise<]uently through the lahors of Max Schnltse, von Recklingliauson,

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-

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-

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

The cartilage ecU does not present any char,

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
appears, the emhryonic cells biicome separated from one another by a

substance is at tiriit slow, it soon increases and condenses as a capsnle

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

nearly all long boneii these cavities are cylindrical, and parallel to the

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

elemetits exist in varying proportions, in the diflercnt bones, and acoonling
to the state of derolopaient of the osseous tissue. In the bones of the

important nutritive and pathological phenomena occurring in bone affect
the marrow.

demonstration; and it appears to be devoid of nuclei. The mfniiliform
appearance is due to the escape of myelin by rupture of tbo neurilemma.
Il seema to us that, during dissection, the axis cylinder haa been sepa-
rated, and frciuently \s found fjoutin;; in the fluid, having a greater
diameter than the nerve fibre from which it appurcntly came. This is

It «ill he scon, in the study of patholog_v, tlint

The entire vtueitlar »yM«m is lined hy such an epithelium; it was
fomnerly iM^lievctl that the cajiillarie:* consisted of an amoriiliotu mem-
brane «itti iiiiclui. Auerhach, l-iberth, and Aeby, employing the pro-
cess of von Ilecklinghauiwn to 8how delicate epithelia, have been able
to demonstrate that tiic membrane of the capillaries is formed of epithe-
lial cells, each of which corresponds to a nucleus of the capillary nail.
If the cells cannot be seen by the usual process, it is because they are
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-
thelial cellD are placed i^ not yet eoniplt-te. It \* [m^^ible that the eapil-
lariea are simply limited liy the mirroundiu;; condense-l connective tissue.
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.

'^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.

the tissues which arc filled with water. :^o long ns oxygen is not sup-

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-

Aged, certain of the glandtt atrophy. Some, as the kidney, become
sUmnketi, the uriniferoua ttibea and their cells are Biualler tlian in tlie
Domial state, sometimes cysts are obserred and the tubes may be seen
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.
The type of simple patlioloj^cal atrophy of the elemenu witliout de-
genonition t» met with especially in the omaoiivtian following inanition or
ncuto or chronic maladie). The mmiL-ular fn^cienli leititeM in thickness

in œdema of the subcutaneous eel lulo-adi pose tissue coincident with
omacialion, wherein this tissue becomes ■:;elntiniform and transparent.
Irritation of ccllulo-aili|>oi^e tix^ue idso ends in the disappearance of tlie
fat, but then the protO|ila.tiu and the nuclei are more swollen and distinct

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
substance flattens while forming the wall of the cyst ; the urinlferous
tubes are discovered to be extremely narrow, with their epithelia atro-
phied and generally also fatty de;;enerated. The same occurs in the
lie pa tic cells compressed by the newly formed tissue of interstitial hepatitis

cases, usually interstitial connective tissue and cellulo-adipose tissue take

a surcharge of fat, an apparent hypertrophy of tlie organ. This i» seen in

Ciireous, amyloid, and fatty bodies. The formation of mucus is exag*
genitcd in catarrhs or auperfictal inflammations of the mucous membranes^ '
anil in articuhir intlftRimadons, particularly in acute rheumatism. It is
connected with a ;;rcaler activity of the old cells, or with the fornintlon
of new element*: these cells are rendered lurgid by the accumulation of
mucus in their interior.
Tbe exaggerated formation of colloii) matter reaches its greatest in-
tensity in certain tumors of the tliyroid body, called gidtres. In some
goîtres there is nothing more than an exaggeration of this formation,
wîiich ends in the production of cysts more or less voluminous, and [loa-
silly communicating with one another. Colloid metamorphosis of cells
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

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

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

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

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.

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

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
ntore voUitninous. constricts itself, ami diviiU's: tbc divieiun of the

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
embryonal cells, but tliey may very soon present characteristic forms.
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.
When a coll prolifi- rates, it gives birth to embryonal or iiulilferent cells.

ni:i»'KJ^Ë, pain, hc»t, and girdlln;;, as primnry phenomena, follo«o<l
by rewiuûon or imhimtion, auppiiration or ganifronir, have served from
Uh) tomt remote antii{iiity to specify the complex stale undcrstocl aa
inflammiition.
Tnlceii siii-*ly, none of thiiw «i^^s belong cxcltuively to inflnmmntion,

wherever ibe voMcl* are obliterated. Kven suppuration is not constant
in inSanimatio» ; it exiittii often without any other ptionoinoiia, and the
couilitioni of the formation of jmis arc so far from being ntiderotood itiat
it IB Dot yet known if every suppuration is necesâarily due to inSammo-
tion. Il is true t)iat in typictl cases where all these <.'hamet«rs ar« found
united, an in plilc^rmon, inHuumution it very evident, bnt a good delibi>
tion should comprehend every inflamoiutory state.
It ti> certflin that Uie iiiHaminatioTi wlio^u syiaptomaiio ensemble we

the application of the simplest irritAnts to tbe ti.isucii of a itring animal
wo can see pro<luced the same chain of symptoms which we recognise id
the clinic as inflammatory.

which have lost the property of forming around them cartilsKiuouH sub-

it destroys the latter.
The ffiitht^lia also con«titule a non-vascular tistiie, usually rcj)o^ng

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
silver (fig. 4:t). In the new-born, the omentum is not reticulated as it

the blood and lyinj>h vessel» may -ho
regarded as analogues of the serous cavities. The endothelial cell» which
lino tlicse vessels have a liistogenetic origin identical with thai of the
cells which cover the serous surface», and they may he looked upon as
transfumMtd connective- tissue corim^de.*. Instead, however, of receiv.

tlie mediation of the lymph, as do the connective- tissue cells covering
the varioiu scrou» surfaces and lying iu the lymph spaces of the organ-
ti*m, the lining endothclia of the bloodvessels arc directly laved by tb«

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

But tbc wliilc corjiusclc* do not forin a continuous layer, as ibcy sliould'
iicconling to the theory of Cohnhciro, which will soon be noticed.
In ititf ifuf-iHtdneou» crllular tUëur sittiîlar pht^nomena lake place under
the itillueiicc (if artttidal irrit>iti(Hi. This tissue contiiin» plasmatic cells
placed in and npon the fasciculi of connective fibre», besiilos «orne adi-
pose vesicles aitd lympb cells. I'he connective- limine cor|iiisclei4 (plait-
mntic eetb) at firi>t hy[)ertr(i|>liy to »twU an extent that the shnmken and
lliinncd uucteu») becomes globular, and the protoplasm becomes granular
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,
the fnniliimonia) fibrous sultstauce of the connective tissue imbibes the
fitiid«. the fibrils become less distinct, and may finally disappear entirely
by a complete absorption. According to ItindHuisch, they undergo a

liplioiition of the nuelei of their cells.
The different inflammatory phenomena
which we have jnat dc«cribcd arc the most
important, for thoy are seen in the non-
niAcnlar an well a* in the vascular tisâues.
Nevertlieletu, for a long time the circula-
li>^ii ha» been Iwlieved to play un immense
ro'i- in inflammation, a r^ilt whieh Cohiiheiia
by hi9 recent cxpcrimenla has reaffirmed,
while nddin;; facu wltieh up to that time had
scarcely boon suspcctod-
Knttenbriinner and Wharton .Tones had
«tiidicd th(; phenomena of irritation upon
the int«nligilnl membrane» htkI thi- tongue
of the frog, and npon the wings of the bat.
Thev saw t!ie rebels first tontract. aflcr-
wardii relax, and subaetjiiently blood st^viri take plaoe, but they did not
follow inflammation beyond iu firAl »tage. We have already seen that
proliferation and the formation of embryonal tissue are essential parta
of llic iiiflnmmatorr prouosH,
Aug. Wfllh-r. of l^ixton. in 1846, was the first to publish an observa-
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
' microscope, showol very distinctly its arteries, veins, and capillaries.
I The aeUon of Uie air, the traction, or the contact of ncoilles amply sup-

an hour tn an hour after tlic coiiiroeiicemenl of the experitnent the vaina
also contract, the circulation ia reiar<leil, there is stasis id the ea{»llft>
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

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-
tation of the comes the plasmatic colls, or eo-callcd corneal corpuscles,
proliferate, bud, and tuultiply by diTislon.

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

that tliure should be added to this cau«c the fnvt demonstrated by VaXov

aru-rinl binod, t* well aa ibc fact that there is often some diffusion into

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.

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

There is not a simple absorption, for, as we shall see when we come lo
study necrosis of bone, an osaeous fra^mont does not become absorbed,
lostead of absorption by necrosis there bas been, on the contrary, a

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

tJic adipose vesicles is a result of inHammaliou at ilit beginning. Per
contra, fatty granules appear in cells developed under the influence of
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>

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

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-

iiuently, those regulator» of the nutritive functions which connect the
cliflerent parta of the same living organism with a common centre. This
abeenoe of nencs impressed Schrceder van dcr Kolk and prompted him to
make tho following experiments : ho cut the nerves of a dog'tt paw, then
prodnced a fracture of it : the callus became exuberant and fonocd a
vorilahl« tumor of granulation tissue. This fact would suggeu Uie iui-
porUikce of « M>rics of researches for the purpose of lenming if the

|irodiiction of a tutoor.
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-

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
be belter named ntvflar fihromn ; in other «as«s tlie cells atrophy, as in

upon the continued formation of a grcal 'pmntity of embryonal éléments,
by whicli the turoora very rapidly increase.

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/-

whieh it pii*»'* in order in Ivcim*^ adult ii»iinfi. Thus, as embrvona)
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

larger in sarc'>ma than in .'<tm|ile inBamma-

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.

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-

^^^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-
tinct, because tliey are seen in a .«ub-
' stance who«e index of refraction nearly
^H «qusU their own.
^B Kre»bly examined, a targe meshed cap-
illary network is seen, in the walla of
^_ which ttie nuclei and the outline of the
^B endotlielial cells can be readily made out.
^V lietween the vascular meshes is mucous
^P tiasue, in which are suspended large pale
^^ fusiform or stellate cells, which aiinstomoso
I with each other by their processes. ( Hg.
Besides this net of plasmatic cells, the
mucous fiuid contains round and «mall
cells [leucocyte*] which hnvenoconnectJon
withtlieirneigbbora. The prc«««nce of the

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.
portant point. Vesaelsare not very abundant; they are found especially
in those parts of Uie tumor whicli po^ess a loose connective tissue, and
tboy consist of arteries, capillaries, and veins.
Wc will describe two species of fibroma.

liave a characteristic aspect. Thoy consist of an afi^lomuration of a
number of Gnn hard lobules. Upon iiection, the centre of each of these
lobules forms a conical prominence, and tlic fibrous bundles wbicli com-
pose the cone arc interwoven in a concentric manner. Several niniilar

poM the lobuIeH are seen to intercross in every conceivable direction, and

Tbe varieties of fasciculated fibroma depend upon modifications of
nutrition.
In some, the fundamental substance is infiltrated with scrum, as to
a,

The SKAT of fibromata is variable. They are found in tlie skin and in
the subcutaneous cellular tissue. Ujion mucous membranes they arc ob-^_

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

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

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.

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

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-

When ^umnuila are about to he develo|wd in the liver, Ihi* formation

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
which tite central c<*lU are atrophied and «^nular, while the peripheml
mIIh are more voluminous and present the character, of nmhryonnl celltt.
The fuwhiment»! eutwtance is va^iely fibrillar, and resembles conuec-
Uve tiiMiM).
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.

aistence sufli^efl for the differentiation by i)i« naked cy« of ^ununata,
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
den^c and hard, vrhich creak under the knife, and whtuh are surroundei)

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.

membranes elabontle a f>oi<ton wIiIl-Ii. wh^u ab.4orbed, proiluoo.^ tuhcrvles.
This conBlitut«a the real relationship between scrofula and tubencutnsts.
The tubercniar ]mison, in moat cases, is tlins manufactured by itio |)ativnt
liimsclf. and it has not yet been demonstrated that this poi^n can I>e
tmnsmittcd to perfectly healthy persons, ao tUnt the disease can hardly
be coiuidcrcd m parelV infi-ctiom.
There in f\nt scrofula, tlivu a cachexia from the absorption of scrofuto;i3
prodoots. I'he intensity of this cachexia ia only partially revealed by
the irruption of miliary tuhcrclei).
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
eourse of the lymph rcssels up to the mesenteric jilaiuU— Aioo/ tuler-

UindHeLwh niv] ijchilppel bvliero that scrofaloua ^ands are alvsjs
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.]

very email cells, measuring from .004 to .ixi!) mm.. t)ie nuclei of which
are surroiindcil by atn--xtremt'Iy ^raall amountof pro.

atrophy. The reciprocal arrangement of those cells
is very important to study. In euvh submilinry

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
from the adjacent elements belonging to the tuberculoua granule by their
larger siae and by their regularly cireuiar disposition within llio vessel

is constantly sarrouinled by a »one of proliferation. It arises from the con-

development of tubercle i^ranulcs in tlie bonus is jireueiled by an oslvitid.

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

In inlanders, as in syphilis and tuberculosis, «r« observe two orders of
lesions: the one purely iiitlamtnatory, the other constituting speoitic ood-

rative.

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
the centre of the nodules, and it is absolutely impossible to distinguish
nue of ttwse nodules in the hoMe from a hitman tubercle. We do iiol.

Should wc, with Virchow, consider those tumors as chondro-earcoma?
We think not, for the ciubryotia) tissue seen around the cartilaginous
islands is simply the matrix whence the new cartila;;inoiis tissue is formed,
and represents the first phase of the development of cartilage.
f: The fibrous tissue which «-parâtes the carlila-pnous lobules is wime-
times predoiiiinniit. Virchow maices these a distinct species, under the
name of '■k-rnHm-jifir-nut.

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,

In !<todyin/ tbe.deielopoi^nt of bone in rachitis. Virchow, after anal-
yziii;^ the piirtiiiilar tisane itesî^:naled hy llufi and J. (îudrin under the
jjsamc of H]>on^oid, called it osteoid tissue, and considered it a« osseous
tissue in process of physioloj^^ical formation. We are obltj^-d to antici-
tte h«ro some of the history of rachitis, whicb we will describe biter in
petnil, in order to explain the constitution of osteoid ti>^ue. In rachitic
bone* «0 often find under the periosteum a tii^uo nnnlo^jout lo hone, in
the owiform traheculx-, instead of eoiitaiiiing bone corpuscles and
■llel lanKllic, show angular corpuscles in the midst of a guhttunce
which is homojieneou!), or nbiob Uà* distlnelcalcaipcous j^ranulca scMlered
Ithroui^h il. Instead of beinj: tieparated by medullary tissue, these ira-
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-
fect processes. The fundamental substJince never become;* laTuellati.'d.
These osteoid tumors may form a single :nass, oi- they may be lohu-
itcd: but they never ptvseni the lohulnted arrangement so markedly aa
in ordinary enchondroma. They may attiiin a eou^derable volume. They
ire very malignanl, and are freipiently reproduced in a great number of
>rgane.

The ostcotnata are tutnora in «liicli are rejiroduced tlie different Tarie-
tiea of osâcoiis tissue.
We will divide tkem, according to the nature of their tiasue, into three
spccice: —
^ft. F,h»rn'itfi i-mttoma. — Virchow found, at the îutcrnal surface
the cniiiimn, ««[enmutu c«m[)0t<rd of concentric lumelliv purullcl to tlti

'1(1. Camjutet oftromit. — These tiiniftr* are formed of onseouii tiii$iie
ninilar to that of tlie diaplijoiA of lon^ bonca. The osscouh aiihstniiue
is diapoaed in lamellie concentric to the vascular canals. Tbey <iifl"er
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.

Certain carliLig-?» frt>iuently uiidcr;;^ osseous metamorpliosia, solely from

True myomata arc alwiiys ^eatbli in the muscular tissue of organ
life. They arc met with most freiiucutly in the utcnis, where they tmy^
appear as an interstitinl ma««, lobulatod and cucysle<l in tbe midst of tli«
uterine tissue, nr as polyps projcetîn;; upon the surface of tlio perito-j
neum, or into the uterine ciiviiy. Their structure in thee» en«o« eoasiaifl
either of yonn^ nni.icu1iir ti^isne, ur of a muscular tissue iuvnilod by
reeiintly-f'^rmed connective tissue, so abundant and predominating that
tlie ifi^wth mti:Ut almost be considered a Rhroma, if, in nttmin;;; Inmorn,
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
Dtnsclo cells with iipedîeji, after the u«e of nitric acid. An important point]
to be obi»erve<l, when .itudying the tiasue in section», \n the shajic and
rolativo position of the nuclei.
Tlie rROdvogiB of myomata is not f;rave nnless by their seat and their
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-
«ulated myomata of the intestine may give rise to symptoms of strangu-
lation.

sur^^eojia to every tumor, whatsoever may be its nature, which may hap-
pen to be seated aIon« the course of a nervo. In the terminolo^j em.
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
nerve tubtdes of new formation.
The name of fiit'/ul ntur'-ma haA been iiiven to certain little «ubt-uto-

Dtipnytren called tiicm painful fibromata. They probably contain nerves
which arc compreiiiied by the new coiniectivc tÎMufi.
Vemeuil baa described, under the name of pli^xiform ei/Ihulrieal nm-
rwnta, an ioterc^lin;; affection of the nervous system, characterized by an
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
a neuroma.
Genuine f««cîcui(ited neuromata are very rare. They are always seated
upon the track of a nerve, and ;iro in every ca:<e fonnod of ti^Mue similar
to that of the nerve. They are genei-ally minll and fonued of a siiii:Io
lobe. Upon a cut surface, their tis.sue apjieant fibrous; it is dry, and,
when the débris obtained by scrapiniJ is examined under the microaoopo,
dro[Hi of myelin may be observed. By dissociation, one succeeds in iso-

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<

muscular cellular tissue, and even into ebc bone itself.
Internal an;;iomata have been observed in the liver, the ktdneya. and
the spleen. The an^pomata of the liver are the modt common. Their sixc
varies from that of a haxcl-nut up to half the sixu of the liver. Nolvrilh-
«taiidiiij; that they project upon the surfact! of tbc liver, they generally
d" n<it augment it* volume, for they are developed at the expen*e of tlio
hepatic *uh«tance. When they are surroumied by a capsule, the hitler is
pierced by vasi!nlar openiii;;*, Armmd them the hepatic substance is
nomial, but is âe|>arated from the tumor by a none of coniioctive tissue in
a state of proliferation. It ia in this proliteratln;; tiitsue, when the tumor
is increasing, that the work of development proceeds. Kuplurea of an;:io«

after spontanoous coagulation, and give rise to cicatrices.

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
ttio capillarÎM. (Slh- Iî;^. 107.) In the ciise of adjcniu iliv hliioilve^teU

thiemia, on the eoutmry, the dilated ciij^tlnrirs arc filled vriih white coV-
pwtcle^, wbieh am readily i>tninvd by carmine. Capillaries full of vhite
bloud-corpuAclcA are aUo met with in all the or^aiu, aa that by this
characterialic alone we can dia^iOiW! after death the leucoeylhiemie coii>

tiKAT. — Lymphadenoma of the lymph glanda determines a con^dvrablo
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
cut «urfuuc open «pace» are seen, which correspond lo the Kwplialic sinuses
envelo]iinj{ tJie follicle. Kveryvihrn^ the enlar;;ed ^laiid.i prenant this
same structure ; ihey arc entirely coni])osed of liie modified conical Aub
BteiK-e.
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
starting point <if this new tiiuiuv. In mlicnia it is almost certain that this
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 adicnia, we have cousuntly met with a notable hyportrophy of the

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

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

Ukkisition. — 'l\ibulated epitheliomata may be defined as tumors com-
potied of plugs orcylindere composed of jiavcment epithelium undergoing
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
a cut surface, they show a tissue resomblia^ a ;;]and or a sarcoma, out
the naked eye is insuflicicnt fur a diuf];noiiis. They yi(dd no jutec by

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.

of the ovarjt have never been observed hh a primary growth anywhere
but upon mucous menibranea covered with siwilar epidielium in the nor*

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

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
diffcTcntial diagnosis between these tumors and adenomata and papiUo-
mau, à prirp'M of the latter.
Cylindroma.
[Kindfteisch gives the following account of this peculiar and rare form
of tumor, ilenlc called the morbid growth a siphonoma, Hillroth a
cylindroma, Meckel a tubular cartilaginous tumor, Friedreich a tubular

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
which Ktndfteisch saw most distincUy in a cylindroma of the brain, is
explaine<l by Koester by ^le well-known ensheatiiing of the bloodvessels
within lymph sinuses.
Cylindroma ia a tumor which readily recurs, rarely exhibits metastases,
and should therefore be classed near the cancers.]

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
normal papillii;. Diagnosis is ca»y only when examining good prepara-
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.
Si> Class.— Adenoma.
Thtn tuinors correspond exactly with the glandular bypcrtropbiei
described by Lobcrt. They have been cunfmuided with many other
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,
containing cylindrical epithelium.

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.

more or less lai^, which occupy the

portions. The hypenrophied glands and
the cystic vesicles fonn a litttle tumor
which often is peiluncuJHtcd. thus constituting a polyp. In thv uterus,
tbeM mucous polypi may at length project into (be vagina, even as fur as
the vulne. In the uterus, as in the stomach, these byjierirophies of
gUnd« often unite with pajnllary new foruiation* to form compound
(ucaord, villous at tlicir surface, cystic and glandular in the re«t of their
raaw.
Analo^iui lumoM grow in the rectum and tar^e intestine. TIte strnma
of the tumor is fitirous in the fully developed portions ; it is embryonal
in the mints where the gland is budding. If such a tumor of the rectum
protrudes from the anus, the investing cylindrical cells become trans-
formed into sqiiamoua epitbelia, which may oven becone corneous at the
surface. In the projecting parttt in contact with the air, the glandular
depressions are filled by stratified pavement cells; the interglandular
projections then represent pa|)illiv, so that one see« a layer of tubular
^and* become transformed into a layer of papillte covered by a aqun-

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

fect j>iiiiililude with the ju-evioinly described uterine lumora.

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.]

The derm wliich covers it is tliinned at the surface : its napillœ arc flat-]

structure of the cyat itaelf, there is proscntt-d for consideration first \ls

At the internal face of this mem-

in sebuceoiis (•land:'. The cells in contact with tliv wall po«scsa )arg«.J
nuclei siirniiiiiiied by a small iiuaiility of protoplasm (A, fig. 120) ; and"
"t is probabh' that it is hen- that the new e<'lls iiici^.itiintly form. In
eerlftiii cases thf fatty evolution i.* very sli>w, uiui tiie layer of corneous
cells, in which the nucleus has cotnpleiuly disappeared, is thick, and often
detaches itself from the wall of the cyst, and forms a shell consisting of ,
whitish, slightly translucent, almost cartila^iniform tissue; it Is at thai
interior of tliis shell that the meliccrous or ateaiomaious contents are
found.
d. Dermoid '-i/Ff», which, like the preceding, contain a steatomatoua i
matter, aro developed ouuidc of glands, and are cbaractcriied by a wall
having a structure analogous to that of the skin. With Lebcrt, we may
recognize the three following vurielies: —
1st. Tho first variety of dermnid cysts is that which verv strongly
resembles wens ; the sole difference relates to their wat. 'fiieae cysta
develop in regions where aehaceoiiâ gland» have tinturnlly no existence,
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
these cysts wc find matted hair in tlie midst of sebaceous matter.

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.

neck of these depressions may give riao to little cysts. The name of
•l<in;ifi'/n» has bccD ;;iven to them, and ihey are observed especially at
the wrist and the buck of the foot.
Hydroceles of ihc tunica vaj^inali» and hydropsies of (he articular
serous membrnnc may be classed with the pree>cdiu|> cysts ; tUcy ap[»car

Thette occurrences serve really as intermediate links between the [tfO'

i. Oysts develofied from gUndei are very numerooa. The thfirmd
hJif is aloioet a physiological location for ihem (,see Thyroiti lîojff).
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).
The viW'iHi yUititiê ••/ tlir lifs become transformed into tittle trans-
parent cysl-* "f retention. The buccal mucous membrane may be UfUd
up by volumintiibt cyslrt resulting from the distension of the duct« of
Wharton and Kivinus; the l&tt«r swellings arc dosigitatod under the
name of runuUi.
In the »t'iiiuifh, the luttHliitr^ and the tnichfa little mucous cysts,
either isolated or agglomerated, often result from distension of tlie
tubular or acinous glands.
The ^t'vfr sometimes contains cysts inclosing bile or coloring matter,
or simplv a serous liuid. from distension of llie biUary ducts.
The kidney is very frequently the seat of variously produced cysts :
congenital cysts, sometime» very voluminous and very numerous, duo to

vrall. and are then irregular, anfractuous, and paved by n cylindricnl
ciliated e]>ith(']ium.
'li\. MuUilocular cystâ may appear in rausole*, tendons, bones, the
brain, etc.
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

to deny the mode of dovelopnicnt indicated by b'<x'r«tcr, but wo Iiairc not

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.

In the fœtus or at birth, sometimes voluminous tumora are found, con

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.

Af^er tlie definition which wc have jiiren of tumors, we dioald XKDgfi

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

destroy iJie ti&iues and are generalized in all the organs like tlie most
isalij^ant tumors.

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.
Bniic U iiol the result of a direct transformation of connective tissue or
cartilage, Ibe cellular elements of which first proliferate in order to fom)
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
asnst in the foroiatiou of a true connective tiiuue, a-t may be seen .sur-
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
bones of young persons, ami those of the niluU which cont;iin embryonal
narrow, tn the sternum and bodies of the spinul vyrtehne, are particu-
larly liable b> nutrittre or fomialive pathologiuil alteration». Moreover,
diffcrcut parb* of a hone are not ei|uûlly subjccl to disease; the youngest
portion, the nujwrficinl or suli-|)erio!iU'al, and that which form» the ex-
tremity, eiifiecially duriug the growth of the bone, are localities mojt
frequently attacked.

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.

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
corpuwlea at the edf;es of tho notches open, pcrmittiTi;; the contained
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

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.

At the present ttm? such an explanation cannot be admîtled, .«iiice we
know that boue corpuscles do not proceed direct); from cftrlilaginous

(). ^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.

and traTene the eniUrvonic tiiuue ; along the aides of these trabecutie are
seen numerMis celU, which become angular : some are partir imbedded
in tlie yoimg osseous snbatance, which is formiu» around tiiem. It is
not iiece9<tary that the periosteum sliould coTcr the lion?, in order to hnro
a new formation of osseous tissue upon it« surTncc ; but the preMTiatimi of
the perioateum, and especially the rcawls of tJic under «urface of the
periosteum, which enter the tlnvcrsian canals, nMist gn-atly in the fonn-
ative action. TIte ext«mal surface of bone i* not the only part in which
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
tiMue, vbtoh are devchipcd in a :«iim1ar manner as upou the extenial flH^
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
Troja, that at tlii^ time the o^seou» tintiue included between several
canals has been »b»orbi.-<t. Tliiii absorption continues until the whole of
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
the atmly of the several varieties, neither making special chapters for
acute and chronic osteitis, disiincnons nioro interestin;; clinically than
in a patholoj^cal point of view, nor considering nrpantt«ly pcrio«titis

tation is most active, that is to say, upon the cut surface of the bone andj
in the mi(l«t uf «ii|>pun)tion, but jtortiv distance above. When tliv nlumpl

The snh.|ierioât«al o^eouii fomiation«, coïncident with the abaorptioQ^
of the old hone, should not be considered as indicative of an '«aieo-|
LKenetic property of the perioâteum: they iu reality epriiig fi'oiu the em-

Uie Haversian cutials, under the influence of irritation.
During the cicii tri za lion of the wound newly fonnod o««eoua Uttstie is

2. RAUEFYlxii Osteitis. — Inllammationof bone in which the ati
tion of the osseous substance is a prominent feature, and in which
enlargement of the Haversian canals continucH until the complete disap-
ncaruncc of the bone, is named rarefying osteitis. This variety of oateitis
IS peculiar in the absence of any attempt at new ossification : the new
embryonic tissue generally protrudes externally, is covered with largo
fleshy granulations, and discharges pus.
Karefying esteitjs, as above described, is a disease not frenncntly met
witlu It oceiin» in the short bones of the u|jper mid lower extremities,
either as a result of injuries, or following a continued irritation, as a
perforating ulcer of the foot. In the latter disease especially several
pUalangea may completctv disappear without ttay oecroais, yet necrosis

the process only being more intense and continued ; extending from
the suppurating fociw until both estrcraitica of the bone arc reached.
When tlic epiphTsis of thv bonfl is absorbed, there is produced a suppu-
rative nrthritis. There rcniaine no trace of tiic bone or cnrlilnge. except
ptThiipH a thin, 0])a<[itc, friable lamella, formed bv a cnleifiei) layer of
the dinrthrodial cartilage, which may be readily recognized witli the
mioroscope.
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

4. DlFPxi.SBi> St'PPrR.^TlVE Osteitis. — This variety has received the
names of oatm-myAitia (Chossaignac), of phU-jmonom prriottili»
(Giraldi<),of rpmAyvnil osfeiW*. etc. We believe this disease to consist
essentially in a «iffusea suppurative inHammation, which may be located
in any part of the bone, under the périoste uni. in the stiperficial layer»,
in the substance of the bone, or in the central mi-dtillary .«nbfltanc<.-. A»
it attacks yonng persons especially, and as the phenomena of growth
of tlie bone takei< place under the perio^itenin and at the epiphyses, the
physiological activity of these ]iarts favors a more intense inflammation
tbaa in the other portions of the bone.

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.
Beet, in.— Heerosii,
nth the majority of authors, wo give the name necrosia to mortifti»-!
tion of bone which occurs in eonîei|uenee of an iiijiirtf or an OtUittt.
Necrosis is occasioned by arrest of circulation, most frcquentlv owing to
eomprcstion of the vessels in the Haversian canals by pus or oy osseous
new formations. The mortified bone in process of elimination is itamed
a sequestrum.
French surgeons separate the scqucstrEc of necrosis from those of
curies. When speaking "f caries, it will he seen that this distinction is
legiliinnte, not only from the naked eye chiiracters, but also by the pro-
cei* of formation ns revealed by the microscope. At prêtent we will

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-

it will be found that the diploij has been changed into a compact ti^ue.
An invagination like that which occurs in long boneâ is absent in Hald

at the edges, and incases the eei|UC4trum as a watch-^laas. Formative

osseoai layers may be so arranged that the lumen of the canal does
not correspoiiii lo the centre of the original canal. This process con-
iinuio;^, the cunal may be completely ob1itcrate<l, so that at the centre

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

in conseijuoDce of a losioo of tlic bone, which randors it friable (cancer,
rachitis, etc.).
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.

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
ppriphcral callus In the course of formation arc increased to such an ex*
tent thai Uie fasciculi of the connective tissue and the cla:jtîc fibres have
almost enUrely disappeared, while the bloodvessels especially at the
margin of the eallus have become greatly enlarged. It i» at thi« time
thai the ceil* of the peri]>heral callus are found to be imbedded by a
cartilaginous substance, while the cells of the peripheral marrow remain
always free. At the period when the peripheral callus is cartilaginous,
ibe bone itself is entirely free of cartila;;e.
From the icnih In the fifteenth day, calcareous infiltration takes place;
it is seen in disseminated spot» in the proximity of the bone. This
infiltration, however, is preceded by a proUforation, which is similar to
that occurring in the physiological ossification of a short bone. There
arc sevn large cartilaginous capsules filled with secondary capsules which
open one into the other ; afterwards the calcareous incrustation of the
cartilaginous substance which separates them takcii place in su«h a
manner as to fonu areolar spaces wldch communicate with the [teriosteal

the medullary euual into two pari». At a ranch later period and hj

witli diSicnIty anoid fraciurc can be reco;niixed. Therefore, I>upayt7en
was right in naming peripheral callus provisioual.
We said that all the adjnccnt soft parts contribute to the formation of
calhit. Muscle is no excoptiou to the rule, as has been pointed out by
CntveilLier, yet the fn»cioiiH of the muscles take uo part; the iuterfiw-j
eiculnr connective tissue alone is the active element. The primary fa»-
ciouli undergo fatty mctamorphoei*, atrophy, and ^raduiilly dîi'apiH'ar.
'I'hu* two mi.-lhnd.-i for the fonmition of callu» are (ib*cr*'i>d, de[>eudiDg
upon the nature of the fracture, whether it lit simple, or acoorapanied
LVitfa an external wound (compound). In the latter, oitsi&catton takes
Jace directly from the embryonic or granulation tissue, while in the
Ibrmor bone is formed from cartilaginous tissue, as occurs in physiological
osmficatton. In the present state of science it is impossible to cxplùn
this ditTcrunce. The prvsencc of bone acting upon innamcd tissue caniwt
be the cau^e, since it is the same in both cases; nvither can it be »_
different doj^ree of irritation, for in formative osteitis, whether acut« of
chronic, the formation of cartilage i.s not oh.*erved. When in a fmat
mammifcra the bone ia scraped .lo a» to o|>en the medullary canal, tha-^
loss of substance is supplied by an oafteoua tâ.saue of new formation,
which is not preceded by cartilage, even when the wound has united by
the first intention.
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
found. Soft primary tumors, of rapid proj^reas, which are developed'
in a booe, invade it gradually by <lcalroying tlie osaeous tissues as

which exists at the margins of the sac. From a nakedeye examina-
tion carelessly made, these sacs are liable to be eoiwi.lered aa aneurisms.
Mucoid uietatDorpbosia is also seen is these tumorâ (see p. 8t().
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

of the marrow ; for, if the granulation U pvncilk-d, it is not di^fintc grated ;

Tht.* meiho<l of examination, however, is very unsatisfactory ; in order
' to study iho iii*siie of the granulation, and obtain good results, tliin sec-

in the section presents the following characters: at itâ periphery, the
marrow contains no adipose cells — the bloodvessels arc dilated, and bavo
no connective tissue around Ihcm; this zone of irritation fn-qucntly ex-
tends some distance into the spongy tissue, where the osseous trabecuUe

The osseous irabecnlic included in the caseous mass have seldom]

alteration of the osseous tissue, except rarefaction.

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.

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-

These different tumors are developed u dcsctibcd at page 129. In

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.

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-

epithelioma has been re|>orted by Oawrilofi'; this ia not surprising when
it is remembered that these epitheliomata behave as carcinomata in their
generalization.

of nutrition and of development of tlie tissues which contrihntc to ossi-

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
irabecube. when young, |>ermit the cartihigc with its cajwules to be dis-
tiiiguiniicl — -the margins of the latter, however, are diflicull to recognixe,
owing to the eatcareoiis incrui«tation. In older trAhecul»;, the capsuiea
are entirely hidden, but in order to niabe them visible, it anflices to dts>
solve the calcareous sall^t with hydrochloric or chromic acid. It may
happen thai these reagents do not reveal the présence of cartilaginoas

Iplttanncv of a tncdutlary membrane. It is posiiihle that it waa tliis
«tuition which led the »hl anatomists to admit tlie exltitence of a roe-
Aillarr membrane.
The layer of marrow beneath tlie periosteum, which has been men-
IWiT'l «cvenil times, is Gban;;e<l at the commencement of the disease into
imft couticctive tissue ; later it becomes more solid, adheres to the «mder
lurface of tlie periosteum and to the hone, m that its reparation frmn the
boM is much more diflicuU than t» euMtoniary in youn;^ [tersona. This

of «hivfa ts not determined, consisting in the appearance of waving refracU
iug tralwcul^, anastomoùng one with the other, which come from a ti-ans-
fonuttoD of intercellular substance of the young connecûve tissue.
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
tbem iwwevor by containing cells in their interior. The tissue which forms
'liieee traWcuta; is considered by Virchow u» repri^scntins the first pluiso

exppilÎGUt to Kire, in a eoiicW manner, the structure of tlie most
Drtant parts which enter into the composition of joints in a normal
tie. Tbo cavities of the (litirthrodini a nictitations arc limitoii by the
faces of the curtilages and the synovial membrane. The elements of ^
be 'liarthrodlnl cartila^^cs havt' an unvarioil arrangement. When a
svrnto «ectioii of tiicst carlilnges is made, there is seeii a nnmhcr of
Friin[a>sH layers in n-jmlar onler. At the free «urfacc the cap^iulcs

I «ily fine coll like the preceding ; deeper the capsules are len;'lhe«e<l jier-
1 fmficularly to the surface, and contain two, three, or a greater number
*f Baofindary capsnloa placed one behind the other. The enlarged pri.
■arr capsules form linear series which are continued into the deepest
liTtrs, where there is an Infiltration of calcareous salts, uniting the
hjnfine eartita^e with the o«»cous tissue. Ail the eclU contained in the
ales at the surface and in the middle layer inclose granule» and even
^èôp* of fat. 'ilie caloiGeil layer i» boimded on the cartilage side hy a
■uoi» line ; on Uie bone side are hollows and prominences, in which fit

tMh of these osaeouH ;>a]iâllie there exists a medullary and vascular cavity
B Gommunicaiion with the medullary and vaacnlar tissue of the spongy
nbetance of the bone. If, therefore, the plasma of the vessels goes to
the hyaline cartilage, it must pass through the osseous layer and the layer
j tf calctBed cartilage. Yet these last layers do not contain canals, and do
|a«tappear perméable ; so that tin- nutritive miiterial reaches the cartilage
fin son» otlicr way. Very probably the tintriment comes from the fluid
«lûch hatlies the articular auifacea, and widcli 'a exuded from the vessels
of the «ynovial ntembratie.
TV «rnovial membrane presents for consideration a plane stirfaoo and
a Tilk)u« «iirfacc. 1'he plane Hurface is composed of layers of fibrous
tiMDe intenuiugled iriih numerous elastic fibres, in continuity with the

In t)ic i>liyAi(ilo^ctil ittntc, hencath the proHfcrtttinfç cartilage, in foind

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.
Tlio Uyi^r of tnarrav beneath th<> perioat^uro, which has be«» men.
tioned severs! times, is changed at the commencement of the disease into
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
con m-ciivc- tissue layer, truly sab-periosleal, at times acquires u consider-
nlilc thickness. It undergoes a very interesting moilifi cation, the natunJ
of Tihich is not determined, consisting in the appeanincc of waving refract-
ing traWculiu, anastomosing one with ttiu other, wliich couie from a tran»-

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

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

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-

upon the «umber of cellular elements and the degree of their fatty

As seen in tranaverse sections, the superficial lenticular canali

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

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).
'So that in the deep layera tUi^ scgrnvnt lincation \» per[)eiiilicular to llic

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

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-

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.

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-

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

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.!

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-

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.

£. Goorr Arthbitis. — Goaty affection» of the articulations, like
scrofulous arthritic, are divided into Ino ^lage^. In the first there is
seen a simple nutritive te-sion of the cartilage, of tlie .'«ynovial membrane,
»oi) of the nnrroundiug fibrous t>»sue, which in tlie Hecond stage excites
a true intlAnimution.
Fir»t Ulaift. — The legions of this stage consist in an infiltration of
nmt« of wda, generally in the form of needlo-like crystals, into the car-
tilage, the synovial membrane, neighboring fibrous tisHue of the arcàcula-
lion, aud even into the periosteum and wreolœ of the spongy tissue of the
epiphyses.
In the cartilage, at first tho urate of soda is deposited in tbo anper-
ficial portion, never upon the surface, as an examination with the unaided
eye would seem to show. When the articular surface is examined, it
appoanlike a chalky and polished layer, usually glistening although very
opaque : at times scarcely perceptible riilges are distinguishable, and
are very irregularly arraDgeu.

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

When the peri-articular deposits of urates attain «uch n sîxc as to be

in the centre of these chalk-stones there iii found a white pulp, which
being removed leaves a cavity, the wall of which varies in thickneax. Wing

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.

ecchondroM-a are .'^mailer than those in chronic rh(nimati.im, and the peri-

f'r'-h'm-tfoifi ori;^inatin|i; in the interrertehral disksi, however, do not
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
he call* Ji-mlrilic, ehiiraeterixed by a number of lobules se|>amied from
each other in the articular cavity, yet united liko a hunch of grapes.
J'hysiolojfically, the ^ynoviid fringes contain adipose tissue ; the den-
dritic lijioma may simply he an exaggeration of this. The affection is
Tcry rare ; we have never met with it.

It is certain that, up to the present time, the arthritic ivhicb aecomna<

witJi scrofulous artliritls ; yet tliese two affections seem to us very
distinct. 'I'he aymptomatelogy of tuberculous artliritis is entirely
unknown.
Tittnort hiieinff ihrir Ort;rin in the Ntij/lif/nrinif Part* and I'nttt-

sarcomata which arc the m«»t common of ail, seldora penetrate into the
articular cavity. The calcified laver of tJie cartilage does not ao readily
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
cavity. This penetration has been prece<ied by all the phenomena which
have been previously described uivlcr chronic arthritis by continuity.
In some person». and purtîcularly in children, there is seen a liw* of
eubMlance of the nrlinilar surface, cut out as if by a punch, vsUiblishing
a communication between the joint, and a cavity of varying sixe ex-
cavated in the tij»ue of the epiphy:<i». Tlie ot»cou« tissue which limits
tliiii cavity is rarefied, filled with granutadon ti^ue infiltrated by pus, or
is condensed. The surface of this cavity is lined by granulation tissue
or by a caaeona layer. In the interior of the cavity there is found
pus or caseous matter more or loss concrete. The arlicidation contains
SOS, and all the changes of suppurative arthritis are seen. All surgeons.

The margins of the perforstiona in the carriage show a proliferation
of the oarcilage cells as in other oases of chondritis.
It is necessary, therefore, before coming to a positive conclasion,
to wait for new oases where the changes are more recent, or cases in
which, by the side of the old alterations, we may find points presenting
the characters of tubercles of bone, aa has been seen in Pott's disease.

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*

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-

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

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

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).

in rare cases where the disease terminates by resolution, there is never-

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-

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

these last coming probably from the ii'liposc tissue. I'liu shreds of oonncC'

Sect. TI.— Chronic Phlegmon.
I
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.

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
one u[)On tJie other ; between the fibres there arc found fiat cell» arnin;;e(i
parBlM to the surface of the membrane. The development of the:>e cynts
bas not been studied, but it îa very probable that >t Ls tbc same as tliat

In traumatic hemorrha^^en of the serous membranes, notahlv in the
hemorrhages of the peritoneum following a wound of the abdomen, the
hœnHttin which eomes from the ducoroposiiion of the red blood cells is so
abumUnt that, upon opening the alidomen, it appciini as if soot had been
spreuil ti|>on the great omentum and intestines. L'pooi the great omen-
tum the black matter i^ seen in the form of very deep brv>wn oprnjue
granules, spherical or an;;idar in shnpe. Tliey are located in the white
blood corpuscles which fonn collections between the fibres of the reticu-
lum, in the endoilielial colls lininj; the fibres, and in small groans of cells
that surround the «diposo ti-*suc, whicli the_v partly conceal. I'pon the
intestines the peritoneal cndotheliinn is also inKhratcd with black gran-
ules, and has the appearance of the epithelium upon the clioroid coat oC

The absorption of the ha'matin frrnnules from these locations is effected
probably as in the eonnectiw tissue, by the lympltatic vessels, ihrouj^h

IMmeli-alion of broken or entire red blood cells into the interior of then
cells, some of which are detached and float free in the carity : afterwards"
the formation of pus cells and a fibrinous exudation. The rod blood cells
undergo changes, first studied by KindËeisch, similar to thoee seen in

In hcmorrhnj^ic iuBammations of other serous membranes, sometimes

fibrinous pleurites, where a primary paracentesis thoracis gives a sero-

derived from them are pre;«eiit.
The piw formed in serous cavities very rapidly undergoea nutritive
changes: the cells are filled with fatty canules, and when the fluid haaj
been partly alworbeil, they become caseous. This caseous pus forms
yellow opaiiuc masses havin;; the consistence of putty; formerly it was

tals are present.
>?olid fibrino-piirulent exudations undergo the same changes as pus
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^
of the fibrin and of collections of fut j^aunles, of crystals of fatly acids,
of cholesterin, and of bliiod pifjnu-nt.
The serous membriine at thi* time is considéra hi y thickened and vas-

This new tissue i» very liable to calcareous i ililtration, which forms hard
bone-like plates, varying in regularity and extent. We have never seeiH
bone coqiuscles in these bone-like plates. '
A thickening of the pleura is especially seen around oiasses of caseous
pus. Sometimes the change is limited t^) a single portion of ihe seronsj

The ilcrelopmcnt of tubcrcidous gmnutatioiia upon th« surface of

from the connective tissue of lhe«e meiiihrano^, for tliere are fouixl, Iwncath

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
the liver, stomach, or in the gr<-al omi-nlimi. Ft present the form of gela-
tinous plates with vuscnUr marLiu;*:* .tiid "f ecohymotic points. It is
"ifeloped from the connective ti**ue of tlie serou» membrane or tho sub-
''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.

Voluntary mu»clcs c«enlialty consist of strialoJ muscular fasciculi

other, bouiti) together hy oxtroim-ly thin fibiv!> of connoctive tissue so
M to coiutitute dii<tinct i^roiifis known m iiecoiitlary fasciculi. Thcsv
seooDrlary fasciculi arc not »»rrouu<)cd by an amorphouH continuous
membraiiu simitar to the sarcoleininu, which surruumU tbo primary fas-
ciculus.
Between the secondary faticicuii arc placed tlie arteries and veins.
The iiipilliirics pooelraw ilic aci-ondary fasciculi and arc dtaipilm«d be-
tween the primary fasciculi, tbrmin;* elongated rectangular meshes which
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
and afterwards completely dissolved.

ont any nutntive change in the tnusoular faflciculi, or, vice versa, very
advanced modlRcatiaiis may occur in the contractile 8ul>fitunc«, without
any alteration of the naclei. .
Athopky op Ml'srCLAR Fascicui.!. — Atmphy of nmiicular faitciculi
noay coincide with gennral utrophv of the muscle, or itith the préserva tioti
ana «vcn îiicrenM of the sise oi the whole miucle, when there i» au
increase in thickness of the connective and ttlipose ti**ne. 'Hie varioua
tumors of miwclea alirays cause »n atrophy of the muscular fasciculi.
The muKcular fasciculi of the entire hodyare ati-opliied in emaciation.
All the fflHciculi of a muacle may he affected at the same time, as in in-
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^

Hïi'KimiOPliY OF MusrLBS. — Hittnlopeal atndy of (he hypertrophies

or |mth(>l<i;;inil exeiviM!. it i* difficult to dcWniiinc if ihii" hyjiertrophy he
due to a iH'w foniiatinn of muNUnlar fa^eicuii, or to an enlargement of the
old fasciculi. The difficulty '\» due bi Ihc fact that tlte faaoiculi varjr
v«rv much in sine in the same inuule in the norma) ^tat».
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.
Cu>0i>ï SWEUjxo OF TliB Mr3Ci'L.4K Fascicit.!. — This is rery often
the first phase of fatty degeneration. In this alteration the muscular fas-

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
fasotculi present a certain resularity in ihcir arrangement, being placed

It is very probable that tho fascicnii which have undergone fatty de;;e«.

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

rienced thi» change are destmyed by a process the different phases of
which cannot be well folhiwcd. The fatty ^rniinle:» become more and more

The number of fasciculi afTcctcd by the defeneration is always limited.

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
f aupen-encadarin-^a fever, it id ni'>st frei|uently seen to attack the anterior
'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

clinU'd ill ili9 rujttiire contain a clot, in nhicU if (he Icaion is recent the
rwJ blooil cells are well preserved, or granular if llie lesion ia old.
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<
curriu}; in the extrava^^atod blood ; liiit as yet nciiht-r upon anitniiU or
man has the nu'lhud of this abeorjition been dulerniincd. It i» known,
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
liaaup. 'llic extiavasated bloa<l ex|)erienc«B the usual metaraorpliuAOK ;
at lirai it ooagulales, then decomjioaes ; the tihnn undergoes moWular
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

epithelioma developed primarily in the antrum or nasal fo6S« may also
spread to tlic muscles of the lace cither in a diffiised or circumscribed

Th« morphological ekmenta of the liloni) in the normal atate are red
and «hile corpusclca: there are abo found eleineiitarT ^ranulea which

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.

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
decompoM-d. The spectposcopo detects it in very weak solutions: in
cotvcentrated solutions it cryxialHics. Crystals of bicmo^Iohin are ob-
tained by several methods, all bavin;; for theircnd the dcftrnctiou of the
corpuscles and the libcnition of the hicmo^^lobin vtilbout the aid of wat<T.

Ilsmatin is of natholo-^cal importance, since it is formed from blood
^^ extravaaated into the tissues. Il« formation is slow. The varied colora-
^H tions of ecchymoses, as has been shoivn, arc due to the slow transfonnation
^* of hsemo^^lotun and his'natin. This chaii;!c is much more rapid if the

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.

Sect. It— Pathological Histolo^r of the Blood.
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

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.]

coincidence of hypertrophy of Ihe loft heart, and of atrophy of tho kid-

i* >)illiciilt to undenttntid how the inconvenience to the circulation in mi

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.

■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.

layer fonned by elastic tissue and fasciculi Df connective tissue.

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

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,

lating blood, are extremely amiiU. and may be carried into the capillaries,
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.
cardiuni upon the oritices, is a cause of oarrowin;; (stenosis), and by the
rupture ot Ihc valvular aneurism, it may occasion insufficiency. Theae
letuuns, however, arc more often produced hy chronic endocarditis.
A series of lesions of the heart, occurring espwially at llie orifices,
are coniieeted with •■hr-ml'- rnihu'itriUti* ; some have for a chuso acute
endocarditis, which has passed into the chronic slate ; the others arc de-

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
dilated by blood pressure, the fibrous rings of the orifices fre^juontly cx-

There are always found in this imperfect fibrous tissue small points of
fatly degeneration. These points, uniting together, may form atltoro-
matous foci filled with grauiilar detritus; liiese atheromatous pointa may
be stationary or they have a tendency to open upon tho surface.

process of this nature, but it is impossible to follow the process from lii^

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

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
ttmioa odveniitin.
The external coat is traversed by arteries, cajnllaries, and reins {ra»
rnsorum) and, by lymphatics whose lumina appear as cleftH when cut
transversely. Small nerve trunks and isolated nerve fibres are also seen
in tbis coat. The small arteries possess a middle coat fanned by smooth
.nuBcular cells arran^^ed tranaver&cty, constituting a continuous mumbrsne.
^91ie tunica adventiiia of these arteries consists of very fine fasciculi of
connective tUsuo having a goueral longitudinal direction.

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
surface. Thoircolor iâli;;hired,transparent,or opalescent; theircoivsist-
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

Cntn.<)luceRl, light red, or colorless. In some cantos wliere tlie emlartc-
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.

theory of (.Vhnheitu, acconling to which the wliite corpu.4cIe-t emij^rating

apply. A careful study of tiiese elements distinclly dcmonstnted thai
they eome from a division of the fixed cella of the tissue.
Tlie jtelatinoua patches of the arteries at times present superficial and
funj^uid ulcerations, which are covered by a thin Inycr of adherent fibrin ;
this occurs more frc(|neutly in valvular endocarditis than in endarteritis.

And striated, or it is so in patches. It cannot be dcterniitiud without mi-
croicoptc examination whether the structure is fibrin or the modified
inienuil membrane. 1'he parbt corajMsing the traiuparent layer, whea
stndied by diasooiatJon, are iteen to lie numerous round, small, nucleated

embryonic elements come from the pmliferati^nof the cells of the internal
membrane or from white corpuscles of tlie blood. But if sections are
BUul«,it is seen tlint thoy consist of fibrin inclo«in]> cellular clementj. It
is veiT probable that the fibritioj^cnic substance of the blood tstransfonnod
into nbrin by the action of the fibrinoplastic substance of the infljunod
parts, nnd tliat this lihriu incloses either the white blood corpuscles or
tlie proliferated and free element)* of the discn^cd surface.
In every caite of acute endarteritis there exists a cotiHiderahle thicit-
ening of ttie rxtfrtnil fvat, a furrittrttrili», correspond in;; to the whole
extent of the diseased part. Its tissue becomes bomogeneoua. j^el&tinou»,
light red or amher color. Microscopic examination of sections sliows
considerable thickeninK and a now fonnation of cells between the fasci>
coK of the connective- tissue fibres.
Tlio middle -yiiit does not j;encrally present any alterations in acute
endartentis. Between the in<^?t acuic emtitrtcritis and that which ulti-
mately becomes a chronic endnrtcritis, every intermediate staf^c is found;
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-
ternal coat, occurs in phlegmon. The inflammation is most freipiently
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.

ATiieitouA — The lesions of chronic arteritis are analogous to tlie pre.
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.

degeneration which, with atheromatous and calcareous patches, in some
a^od persona extends over considerable space. The while or yellowish
patches shouhl be studied principally by longitudinal sections, or by de-
taching shreds of the internal coat. In these shreds are seen small col-
lections of granules and small oil drops, tVeiiucntly having the shape
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
limited to the internal coat. The neighboring layers of Ui« middle coat
are attacked with Uie same fatty degeneratiou.

From these facta it may he con-
cluded that this lo;Mon occa^iioi» the atrophy of the cellular olemonts of

the word.
CiiiiONic AiiTEUlTls. — When a part of the arterial coat« hae under;:on«
the chan-^ that we have described, the necroMd portioai deteriniiio
around tlium a hIow irritation, pnnlucin;; in tluH manner a chronic vitdar-
teritis.but this is not the only cause of chronic endarteritiit; it may appear
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
matnmorjihoi^is continue» when the InlUmmalion lose^ itd first intensity ;
moot all the cellular elemcntK of the patch are )^enerally Sited witli fat,
instead of hein;^ ne mi- translucent the patch becomes yellow and
HUe. The fatty dejreneration continuing, the groups of granules
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
coat. The pellicle ia tense yet movahie; at iti periphery there is fre-
■[ueDtly seen a swelling formed hy a thickenin;^ of the internal coat in
such a manner that the slightly <lepressed centre of the atheromatous focus
has been compared to aa umhilicatcd pustule of smallpox.

edges of the nlheromatous focus are now colored yellow, brown, or black,
from the transfonnatioD of the hemoglobin.
Such ruptures of foci niay be the beginning of aneurismal dilatatiora^j
which will oe considered later. In aeetions paxsing vertically through the^
atht-romntous focus and its bonloni, it is found tliiit tlie bottom is foniK-^t
by till! inncrinost layers of the internal coal, whicli présent the inoditti'a-
tions of endarteritis with fatty degeneration. The n)»st i^ujierliclal

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 ■
the ve«sel ; genuruUy they are eovoed by a lamella of the fibrous ttssua

at the edge, and the thin layer of tissue which covers tliem i« rupuired,
forming irregular slits through which the blood enters and occasions a
deposit of black pigment.
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-
acope the structure of osseous tissue is never seen: irregular masses
with clel^ and dark stria; are found in a very transparent sulHtiauco,

hy a swelling due to an endarteritis. The** calcareous platen very often
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

When there exist upon the inner surface of the uortn thin, calcareous
TitrcouM plates, formed iu tl» rigid and hypcrtnipliiod internai coat, or
extewUiitf over the atlifromalftua foci, they often hrtak, forming very
narrow slits into which the blood infiltrates. This blood undergoes the
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
the calcareous transformation is found fro')Ueiitly in old persona, in tho
arteries of the mcmhrane* of the brain, in the coronary arteries, etc.;
it occurs in the hypcrlrophied internal cont at 6rst by a chrouic
endarteritis, 'fliis endarteritis is histolopcally charactcrixed by a
multiplication of the celU of the internal coat, and by the formation of
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
of the vessel. In consequence of this lesion, the blood is arrested or
«ufBciently retailed so that coagulation take^ place.

It has heen »een that in the formation of the most simple aneurism — dila-

arc greatly chani^d and hvpertrophied, irhile the middle coat has par
tially disappeared. Therefore this aoeuriatn cannot be considereil as a

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

DtêMf^tng anfHritmt^ described first by I.aennec, owe their formation
to H rapid dilatation duriiiz an ciiduri«ritis. Laennec supposed that,

strated thai tiie hlooil is diffused cither between the hyperlrophied

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.

ObliUrati'm of Ari^f» hy the Li'jnturi'. — ^Thc phenomena following
the ligature of an arW-ry are very oaxily oltservcd in aniiiial«. Twenty-
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
first elastic lamina or internal elastic lamina. The latter, which in trans-
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
entanglvd in a complex manner: they appear fiiMi'onii, but are in reality
dntleiied cell». These cells exactly resemble endothelia, or cell* of the
connective tiaaue swollen by inflammation, Tiiey do not differ from tl»
celU found in acute endarteritis. On the eighth day tlte internal coat
puts forth low elevations, uipplcdike in form, which are ])articularly well
marked at the point of ligation, and are seen very distinctly in traasrerae
MCtJons : in loii<{itudinal sections from the level of the upjier point of tlie

at the place of implantation of tliesc elevations, the middle g«»t of

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-

butt or bsM or the Hbrinouê eht is moro or less closely attachent to the
nu» of colorless elements fortnin» the swollen and inSamed tunica

osHally nttiKh the blood clot to the inflamed liintca intima at one side
(«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
at the bottom and !K>metiiae« also at the sides. The walls of thi* cugi aro

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,

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.

In wonnds, ulcers, and chronic nhlepnons it is frequently «en, in

There may form in these elevations vascular networks, so that, at soma

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,

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

may be easily separated from the old cloi, when it will bo seen that the

Thia theory of embolism has been employed without sufficient evidence
to explain a series of analouiical changes, such as the alwcessea of puru.

Bignale certain le^iona following einbdiitni, ha.-« helped to throw great
obscurity upon tliia cjuestion. Itefore Viivhow, tlii.i word wn# applied to

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,

The tieipielnei of embolism in the artoriea of the extremitjefl and a!! the
other organs vary according to the sîkc, number, and nature of the em.
bolifl fra;iroentfl. Necrosis nr niortitication occurs when there are several i
embolic fragments distributed i» iho arterial system of a limb in such ftj
manner that collateral circulation is impossible. In organs whore the;
vascular territories arc limited, a single embolic fragment may pnxltLce
tiie same effect, as is often seen in the kidney, spleen, liver, and brain.

Gfetew natifl. This blood ex[>ericiice« the changes which have been pre-
viously studied, vin., eranular decomposition ami the separation of 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-
ripliery of the organ. A micrmcopie examination of tlie morbid liaaue
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,

tubules contain fibrinous oa«ts, blood, and sometiincs white corpuscles.
In tlie thti\l stage the white infarctuA is softened ; the Aoftening hegina

This molecular detritus is then t.iken up by the lymphatics of the con-

occurrence is very much like that described as taking place in caseous

Tlie itiveAti^^tioiii* of Cohn)i«iin, however,
show tiiat it \» mnlly mainly owing to the itn-
tiairment of the vitality of the walls of the
hlnndvea&ela, and the consectuent cxuilnlion,
emi;;ration, and ultimate n«croais of the vaa^

impaction of the embolus tliere is a Ixtckwanl
pressure and regurgitation from (h« voiM
into the enpilUnctt. so tliat there i« proiltiec<d
consiilcrabic Tcnoiu engorgement of llic last-

in the ca|>iUiirie^ and small arterieA of venoi
for arterial blood, and owing to tStot tho vi>^
lality of ihene vessels becomes impaired, and
hemorrhage results. The infarction conw-
qucntly doea not occur immediately after tlio
tmpHCtion of the emholu», but ouly alVr th«
lapse '>f a certain time.
The sub«e(|nent cliangtis which take place
in t)iv infarct ilepcnd upon its «ixc, upon tiiC
extent to which the eirctdalion in it is inter-
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.

fused into a single ma-ss, and the wall of tlio arterjr seems to bo consti*
tutcd by a homo;:eneou3 and thickened tube. The calibre of the vesMlj
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
there still remains great uncertainty upon the subject. J
Tumors which grow rapidly ar<mnd arteries of a certain calibre, occ»-^
sion (he phenomena of an arteritis ; namely, a vegetation of the internal
coat, a di«ap{iea ranee of the middle coat, and an embryonic state of the ,
fixterual coat. At times the artery may be obstructed by these ve^l*-^

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 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

thickenji from the foniiatioii of ii^w culU, and forms elevations espvciiilly
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
uo

of pus is seen under ilie microacope, in sccUons of the vcnoua wrall. The
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-
twevii the point of division and the neari'*t valves Hows out, and this por-
Uon I'f the vein n'niaiiis empty. A clot form» ahovc the valves a* far as

in the intlamninliun of the wound ; there oceurit adhesive poriphlebiti» and
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-
<
TnnoHBosta or tbiss.

infareti, etc., is from the arrest of the capillary circulation. It is t}ie
same in leucocylbicmin ; the capillary circulation bein^ interfered with
on Kcconnt of the ;;rcat number of white corpuscles, clots are rca<tily
fonnei) in tlic veins.
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

[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
artery.
Sometimes there are seen, in chronic vnrices, calcareous incnutations
in the form of jilale.*, nodules, or »pber*.'8 with concentric larere. Exam-
ined in the fresh stale, sniiill calciircous pliitcs are not visible ; but, whoo
the altered veins are dried, the calcified part becomes very evident by
ita opacity and the prominence which it forms while the uonual parts
contract and become transparent.
Calcareous infiltration is seen in the form of sphere:* or phlebolites ia

fibrous tiMue in th« internal pnrt of the middle coat, ae))ar»ling the
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
to its moat internal [mrt. KitKilly, the tortuous dilations of the vtua

tumors of VL-ins do not occur.
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.
Thus from primary tumors developed in the general venous syelein,ia
the testicles, in the kidneys, in the extremities, metastasis takes place
DiOKt fre>|ucn(ly in the lun^, while in tumors of the stomach and intes-

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.

ill the production of granular pus cor]>nscles, and in a proliferation witli
dcsijnnination of the endothelium. Generally, these lesions are accoinpa*

It is probable that the granules resulting froia the breaking down of the
foeiiH of softening may be taken up by the lyraphaticii and gradually
removed.
Li puerperal metritis, the lymphatic vessels found in tiie horns of the

From the description which wc have given of the evolution of the car-

it is thus seen that the kI&ikIs corre spoiling to the lymphatic vessels

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.

In th« follicular substance the fibres are less swollen and doBot exhibit
a fibrillar structure ; they are simply strewn with granules.

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

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

^(lands similar to that of the thyroid body.
By microscopic examination, the degenerated parts are seen to be
form«d by a «erie^ of alveoli, varying in «ixe, filled with a refracting
«wlMMuee »iniilar to that fotind in the alveoli of the thyroid gland. Tlie
Alnoli are »eparated by fibroiw irnbeculiv, and freijiiently prê»ent at

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-
formation of the vessels, and at times a vegetation of the morbid tissue

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

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*

found .-«lijihlly Hwollen, and upon thuir i^urfiwe are wen red liiM» running

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 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

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

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-
toms similar to those which may be produced in ftnimals auhtmlted to
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

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.

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^-

Whencei-ebral rheumalism baa existed for twemy-four hours or longer,

is more abundant and is cloudy or even slightly purifonn — appearancea
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«.

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

characterized by the presence of pus upon the surface of the pia mater, by

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.

of the arterial walls. The jerkin;; taipulae of the blood transmitted to
the cerebral eapiltarie.<i is very probably, in some instances, a cause of
dilatation of the small vcasela and of their rupture. But the ci'xt fro-
quent lesion preceding; hemorrhages, and which may he rcganled a«
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*
pised of a ve^^ol and its lympli sliL'Hih disti^iided with blood, and of ao
int<-rstitiiil hemorrhage into the noighhoring nerve tissue.
A fatty detjeneration of the wall of the central capillary is frequently

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».

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
focus, and to investigate the direct cause of the hemorrhage. For this

there is found a ruptured aneiinHm, belo!i;:îti^ nat to a capillary, but to
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,

In the majority of caac», the cerebral tisane surroanding the focus
undergoes a series of moiUiications, which consist in the infiltration of

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

no trace of it can bo found.

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».

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

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-

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-

shown that the legion of nerves pursuci an opposite direction when the
posterior roots arc divided; the part of the mots remaining in connec-
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

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

In the disease which will bo described as tcliraae

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

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

In some ca-ies of gangrenous uleeradona in the insane, the pnriform

tend as far as the medulla oblongata, [ions, and iiiforiur part of the brain,

This form of myelilU, vhcn it ia 'litTi»ed and general, «xtenda for soaK
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,
pigment, and granular i;or]>uMlcs. Tlii;* Tariet; of the disvAAi! is rftpidly
fatal, i.ocaliiced myelitic luiiy present further modificfttiooa, suob lu
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,

A peouiiitriîy of the-tc sclerose.* consists in a thickening of the walla

however, the ei)ilhelitira is very easily *een. The cells uniformly cover
the walls of the alveoli, and their nuclei are placed opposite the meshes
of thi> vaspular network.
The bloodvcjtsela of the lungs are derived from two sotircos : from the
bronchial arteries which are distributed to the bronchi, they arc the
nutrient vessels; and from the pulmonary artei-y whose ramifications are
especially concerned in hscmatoais. The ramifications of the pulnMnary
artery form in the inter-aWoolar septa a network with extremely fine meshes I
which are .004, .005 to .018 mm. in diameter, while the capillariM
forming them are from .006 to .01 1 mm. wide. In the state of contraction
or scmi-iiiflaiion of the nircoti the*e vessels are tortuous, and they elerate
the floor of the alreoli into ridges corresponding to thyir course.
Tlie lymph vessels of tlie luugs «re very numerous. The deep lymph-

HORMAL HISTOLOGY OF THE LUHQ. 398
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,
nerves, and according to some histologists a few smooth muscular fibres.

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

puscles which have escaped from the hloodvesseU, or have formed in the
deep layer of tho mueous membrane. They give to the exuded Huid

An acute coryza, uf a secondary cbaracttT, is obserrcd in the exau-
thcmata, especially in rubeola, in erysipelas oî the face, in diphtheria

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

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.

The latter in characterized by the formation of mi5 corpuscles between
^the pcrichondriuiu and the eartjla;;e. The pus uotaohes and separates
the perichondrium from the eartilago, which, isolated from it« nutrient

typhoid fever, we have wtm the fundamentiil !<uUUnce of the cartilage
very granular and (ho carlilage cell.i Imided uilit fntly granule.-). The
aluceaa by which the cartilage is aurrouiided spreads amon;; the sub-
mucous tissue and the articulations, and {Ktints upon tlie larynx, upon
the plisrynx, or ujiou the skin. It is not alow to open and to discharge
with the pus, fragments of eartilago, often calcified or ossified.
Inie cricoid cartilage is most frerjucntly affected, next comes in order
of frequency, the thyroid and the arytenoid cartilages. In the first two
eases pcrt'oratiun takes place cither upon the Inryngcal surface, or upon
the cutaneous side, and then there may result a subcutaneous oedema or
occasionally an emphysema. When the arytenoid cartilage is affected,
the perforation is into the larynx, and tin.- laryngiMCOjW will therefore

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^

chi. the mucona membrane of which is thickened by acute inflammation,
reailily return to their normal condition; but under the inftiK-nec of a
chronic process, such as branchitis, chronic pleurisy, chronic pncitmonia,
these laocs remain dilated. Almost ulways thc^ tissne which surrounda
the dilated bronchu» is induratad and present» the characters of intersii-
liai pneumonia or of piTi-hroiidiiti*. 'llu' dilataitonof the bronchi may he
cyliudrical and uniform ihrongliout their hMi;;ili^a rare fonn. One or
more bronchi whose diameter i» thus increa.*ed sometime» terminate near
the pleura in an ampulla. There may he several cylindrical or spindlcfonn
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
dilatations, isolated and closed up by the obliteration of the )<mull
bronchus upon which they have been formed, Sinuses exist independ-
ently of bronchial dilatations. They should not be eonfoiinded with cer-
tain space» which may exist between the phura and the faW fibrous niem-

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.

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
the dilatation of thU portion of the lung im|>oi<sibIe. Tlie altered jior-
Uona of t)ie huig may, of course, also bo the scat of tubercles, tubercular
pneumonia, cavities, etc.

Instead of being gray, caseous pneumonia, which is older ai>d in which

the appearance is the same as in the gray infiltration, and the constittition
is also similar.

Considerable masfics of this tuberculous pneumonia may remain un-

and to the blood.
Cavities are farmed in this variety of tuberculous pneumonia in the

has reached the nonnal pulmonary tisfuc the destruction id arrHtcd and
the furrounding tissue is indurated by a chronic inflammation, accom)«-

In this owe the pleuritic exudation contains very many white corpuHcleft,
»n<l tlie elements are often granular. Afier detaching the false membrane,
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-
posited upon the pleural surface. It i^ almost alway» unilateral. Gene-
rally, towards the ctgbtli or tenth day, it ha* reacbwl the maximum of
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-

without the intervention of a false fibrinous or cellular meinbraitc

Purulent pleurisy often ht.it« a long time, even months and yeam. It
may terminate l>y a 8[iontaneoua external evacuation of the ]>us through ao
intercostal sjiacc. Thi» termination is usually preceded by an osteitis nith
caries or necroùa of on? or more riba, and it is preceded by an oedema
of the skin. At other ^mes the pus may discharge into we bronchi,
through the diaphi-agm into the peritonetnn, or pns4 into the modisslinuin
or niniig the vertebral column at. far as the psoiu muscle.

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.

Carrinoma of the pleura very frefpiently follows ii8 development in
the lung or in the bresist. In the latter it ia propneated hy coiititiiiity
of infection to the pectoral and intercostal muscles, then to the iiarietiil
pleura. It is very easy to see upon the surface of the visceral pteiir»
the lymph vesseU inflamed and trunsfumied by the earcinomatoua neo-
plnxni. The*e ves»els may be genendly or only partially aflceted; their
calibre i* dinlended by a more or le*» solid «hilish or yellowish mass,
oonaisting of [Kivement or fpherieal endothelial cells. Careinoinutous
rranulalions of the pleura are small and hard in scirrhous, bnt they arc
lar^r and often dciiresaed at the centre when they are iiecoiidary to
an encephftloid. When these nodules in the coital pleura are deep
aeated. they may press upon the intercostal nerves and produce neuralgia.

iSquam&u* epithrlioma has been ohsened in the pleura from an exten-

also, but very rarely, been found seated upon the pleura.

tlie AtomacU contains not oidy Ruid but aUo a large i|uaRtitjr of gastric

experimental digestion : this post-morlem di;jcsti"n is nuturallv more rapid
io a warm ihsn in a cold eeaaon. Thas Boftcncd. liic mucous membrane
is reduced to a pulpy detritus uniicr s stream of water. This alteration,
which is post-morteni, was for a Ion;; time dcsoribcd as an inflamtnatorj^
U'«ion, under the name of white, red. or slat/ softening, according to the
difTvreut colors which the mcmliraiio presented. 'This post-mortem diges-
tion of the mucous membrane îs met with i» the «Icpendcnt part* of the
atOKoach, particularly in infanK* who often die while the stomach i* filled
with mille, an emini-iitly fermentable fluid which very much favors oada-
veric digealiou. (t ia po^ilile that in cerUtin cadeti inflammation may
coexist with this softening, Imt even then the result is certainly due iD
the main to cadaveric decomposition.

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

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

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

8[Mpi,B UU'EB OF THE Stomacii. — Simple ulcer is ch-iracteri/ed by a
loss of substance, more or less rcgulnrly circular, witli edges so sharply
cut tliBl the mucous membrane ends at the ulcer wtthnut oflering a mani-
festly granulating or i.-vcrt«d bonier. The bottom of the ulcer U jiale,
fibrous, gray, and is habitually covered by a layer which is in process of
molecular destruction through the aodon of the gastric juiee.
These Iojcms of âul>stance are due to a genuine digestion of a limited
portion of the stomach in which the circulation is impeded or entirely
interrupted. At the begitming, the ulceration involves only tin- mucoua
membrane (Cruveilhier). It commences by an erosion of the follicles;
later, the fibrous tissue is invaded and destroyed ; tbc bottom of the
«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
an arteriole ; it forms a cone whose base is upon tlie miieous siirfac«.
Upon the sbarply-ciil stalls of the ulcer sniiill arteries, and u; the ttottoa
of it ont or more larger arteries arv almost nlvrnvs seen with a [Jug of
connective tissue in ibeir Inmeii. Patients affected with this lesion often

appreoiat«d ; in the arterial stump nhieh has funii#hcd tli« MimmI we Mta

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,
Isor new products resembling neoplasms. 'I*he glandular layer at tha
[limit of the iitoer shows tlio tubes mncli k'nj;thened, the inlerLdaiiilntar
connective tiissue richer in polls tlmn in the nonnal stale; the epithelial
cells of the i^nnd are not altered. Beneath these glands the connective
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
ha» invaded and piirtly destroyed the niuscular eoat, bundles of smooi
muscle i^roject upun the wall of the cavity in tlic form, as it wer«,
bnnhes of irregularly cut filnmenl«, coti»isting of diwmcialeil contractili
elements, which may be normal or be in the various stages of faUy d'
generation. The âuhjacent mu.scuhtr tissue aliio sometimes sbowa
fatty grauutes in the smootli mui^cle fil>res. In thia tisaue, and in the
fibrous septa which separate the muscular laseiculi, as well as in the peri*
toncal connective tissue, the arterioles are altered in the same manner
in the submucous tissue.
hi a number of cases, a perforation has formed a communication
between the cavify of the stomach and an intra-pcritonval abscess, aîi
ated posterior to the stomaob. or between the latter and the liver.

thv ntwenco of a lactetwonl juice in tlit- tissue, which forma tbe floor and

of the raiicoua membrane, in conaei|uence of the contraction of tho cico-
iricial tissue, but the )iart de-iirojed is not replaced by mucons membrane,
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
present tvrcnty-four hours atVr death. I^arger cicatrices may very
rewUly become tho seat of a new ulcerative process (Cruveilhior).
Fatal termination of the lesion inny bo induced by hemorrhage or by
jtcrforatioi) of the stomnoh. The»c two formidable acciilents, and espe*
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.

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
by thickened and hardened eonnective ti^'tue. 'i iio^e gland tubes ivhich

to understand and to acknowledge at the aame time the existence, in Ifat

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

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

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

In the stomach the primary tumor often undergoes, in p«rt or in loto,

celts line have at the same time lost their cylindrical form »ii<l become
spherical. Such tamors are recognised b-t cylindrical-celled epithrlio-
maia by the structure of the paru of the primary gronth which have
not siià'ercd the above melamorphonja, or by the fact that the lymph
glands or Ihe secondary nodulea present the appearance of the typical
tumor.
Pacemfftt-ceUed epitheUoma is very rarely met with in the stomach.

SuiLL IsTESTiXB. — The small intestine is composoil of several layers

of flat cvHo ami comii-otive tiMuc; two layers of smooth muscle, the
iDMt exccrtinl loii^itiKliiial, an<l tho most inlcmal circular or trausrcrsc;
«till the miicoiis membrane. It is the lutter which wo have cs[>ecially to
OOORider.
The niucow» membrane of Uie ttraiil! int««tin«, conliniiou* at the (lylorug
with that of the atoranch, form.i in the diioiK-num and jitjuniim the tranit-
verse semilunar folds or valvuhu connivenle*,
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
glands, or in the deeper tiisue. This con-
Dcctivc tissue is covered upon its surface,
whether it be of the villi or of the crypts of
LieberkUhn, by h layer of flat endotiielial
cells (Debovc), upon which arc implanted
the inTc«tiii^ cells, which are cylindrical epi-

pr<)<luced a genuine mortification of the tissue supplied by resâels.
This is precisely what happens in the layer of connective dssue snb-
jscent to ilic glands of l.ieherkfihn and around the follicles. These
more or lesa extended lamell» of the )!landiilar layer are detached by the
Buppuration which takes place beneath them, and arc thrown off in

[Ilcers once formed may continue to extend by suppuration of the
adjoining infiliraled tissue, and, even when circumscriWd, their surfac«

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

Should these softened portions of the follicloa break open and communi-

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.
Very rapidly after the o»»et of cholera and the ooounencement of the

ThU new formation takea place in the înterglandutar and HubJHcenl con-
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^
kiihn usually show epithelium only in the lower pari of their culs-de-ea«
(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-
lium, which is de.iiiun mated.
The closed foUicli;* present the lotitons already desoribod à prapty» of
" psnreniârîe :" their centre has some tendency to soften, and tlteir vcU
I Ittlar elements are fatty degenerattid.
The muscular tunic is normal, but the subserous connoctivo tissue il*
byper^inic and is infiltrated by lymph corpuscles. There may even tw
An irritation of the sennis covering whicb shows itself by thin falMi
fibrinous mendintnes exuded upon the surfucc.
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.
[These ulcerations mav involve the deeper tissues to the extent of per.
'foratiun (Ilamentycky In other cases the intestioe is tiiinned aDiij
atrophied.
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
organisms peculiar to tlio blood of cholera.
This viscosity of tlio blood in the algid stage appears to be the pria-

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
I'eyer's patches were similarly thickened

ctes of IVyer's patches present simitar appearances. I
The number of altered patches varies from two or three in the neigh. |
[liorliood of the ilccciecal valve to twenty, to fifty, extending up the inie»>|
^tine. In tho!!o caseti where the lesion is most intence the jMtch is hyper-'

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
and inflamed endothelial cell» of the reticulated tissue of the mucoua J
membrane and of the Ivmph follicles. These elements are siuiiiar to*

These cells, which have been called typhus cells, luul regarded as
special bo typhoid fever, have no really charactcrtjtic feature*.
Thin sections through the now ulcerated patches offer the following

modification of form is due to the fact that the tissue of the villi ts infiM

is t^uch that the surface of the patches examined under the niicroscopin

gether smooth. J

Such is the structure of the hypertrophied patches in typhoid fovcr ;
we see that it coHsisu essentially of a proliferation of the adenoid tissue
(rilli, closed follicles, and deep adenoid tissue) and of the connective
tissue of tbe mucous nienibntiie, while the tubular gliinds H[>on the mit-

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
of (lie diseased tunic. Those ulcers often have a great tendency to ex-
, (end in depth, sod notwithstanding that they bare a small diameter they

Partial reaorption and removal of the neoplasm of the soft patches mtiy
be cflccted without a genuine ulceration. The fluid mixed with lymiÂ
corp\isck's, which the previously swollen follicles contained, may bo taken
tap by those blood and lyuiph vessels which n-rnain permeable; ami the
"follicles may thus become effacvd in such n manner us to produce rrficw-

mains elevated. I'pon thin sections of these reticulated juktcluM, madt^
liuring tlie i>eriod of repair of the ulcer, we find in the sujierlicial layerl
villi and glands of l.ieherkllhn, the presence of which proves iJiat tlieru
tias been no ulcerative descruclion. Xoi infreipiently we may see one'
or more follicles transformed into a small abscess from which a drop of
serous pus escapes when it is opened. Ksamining, under the micro-
scope, a thin section through one of these follicular nbscesaoe, it is «en
that the pus has been removcil by the handling: there exists in its place
an empty space in tbe midst of the follicle. This space is bor>iered by
à6Un» ot' capillary ve-MOls and fine meshes of reticulated tissue. Tfa»J
walls of IhcHe small folli<riilar abscesses consist of a connective tissue the'
fibn.-* of which are pale and granular, while the [teripheral connective

4th, At the «ul of the third period, commences the process of repair
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
cicatrisation is very slow ; <piite six wi^eks or two tuoiiths or more from
the 1wKinnin>; of the di?iea.ie we .ttill find nmall ulcerated places. Ihiring
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
parallel loDg;itudinnl tibros which arc separated by a large number of
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
by the le«ion; in these case», the piitclie» have been only partially
tinvadeii.

Such are the lesions of typhoid fever, of which the initial leaton is m

Lbsioxk of TtiK lNTKSTt:<t{ IN Hbrnia. — In inftamtd hernia, llic sac
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.
The contents of the stranf;ulated loop consist of a somewhat abu
mucous fluid, oi^cn reddened by blood, or altogether hvinorrbigic.

Boon it |>resent8 ilie analoniienl signs of a very intense iuflamniAlion in-
Totvinz all tlie slructures. Tiio much congested villi are aKoUen, soft-
ened, friable, and shortened; tiicv Qiaj- even be united toother b; a
pwudo-Dtembrane. Tbc closed ^llicles, both isoUled and agminated,
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-
Boope the form anil the structure of a tuberculous nodule, 'llic tubular
gUnds, compressed and occluded by the neoplasm which surrounds then.

Accofdin;^ to the opinion of (rOBjicliii and others, the extensive ulcers
of the rectum accompanieil by indiiraltoii of the connective tissue, and
sometimi?» by considerable contractions, are not characceriatic of syphilis.
Theac ulcere ditfer from those of chronic dysentery in this, that liioy are
bonlcrc'l by a narrow rin;;. and that they occasion constrictions, whilst,
»on the contrary, rather a dilatation of the rectum is observed iti dys-
entery. More frei^uent in woman than in man, they succeed chancres of
llic anus, mucous patches, or condyloinatu.

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.
(ar elements of the altered veins experience the same alterations wbich
have been described à frnpm of varices (sc« p. 342). The connective
tissue around tlic veins may thicken, so that ncigiiboring veins arc united

U'j*lin«, bnt they are very oonmion in tlie rectum, whore they fonn muirtmi
pofffpi, which arc very frc.juent in children. Their type is tlte fKilypu*
of the stoinAch alreaily deitcrihod (see {>. -lliH). Their conitlituent psru
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-
vesting layer of epithelium, which ia in contact with the air, (.'han^^cs
its character ; the superficial cells which wore cylindrical, likc< those of
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
the Rml part of tim manual (pa;{e I4'2). It is especially in the lower
portion of the small iiitetttine near the ileo-ciecal valve, that theae tumort
have been ohnerved. hut lliey may be aeated anywhere in the lenf^lh of
the ga^tro-iDtestiual tube. In two cMei of Picot and Itendti th? oev
formation of adenoid lisMUc bad invaded all the layers of the intestine
and the mesentery, and there had rt'suluîd an enormous tnmor. 'Wvtt
lesionK of the intoistine and stomach usually coincide with other adenoid

the same charactors aa when found in the aiooiaoii. It is often secomlarj
to carcinoma ori;;iiiatinf; in neighboring tissues, the peritoneum, the aterufl,

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.

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
artery are espeoially deiiigne<l for the nutrition of the walla of the portal

The lobules are in contact one with the other, separated only by the

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-
ical countrira ; the most intense hcpatio alfeclions hero met with are duo
to alcoholism, low types of fevers, ty)>hoid fever, variola, scnrlatiiut, etc.,
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.

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.

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

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-

of pmtoplaem surrounding the fat. In a part of the

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-

Rllinj; of the |H*rtid vein ; in the otlicr an increased blood pre«sui« in tbo

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

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-

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
fever, erysipelas, etc., nro acoompanicd at the beginning by a hepatic
ooogestion which precedes the cloudy :twelling of the cells, and their
fatty ilegetierntion. Thi» is a tfandient state, soon marked by the de-
generation of die cells.

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

atrophy of the liver. Tlu-y arc »cva in u iiumbor of liver ilî«ca8C« nocom-

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|.
iary canals were cliamctcriïcd by the csislcncc of a structureless mem-

These lesions of the solids and fluids may seem to cxpbiin tlie sjnp-i
toms observed in grave icterus. They consist especially in the allcraiia
of the blood. The latter is poor in rod corpuscles, and it contains bili-
ary coloring matter, and a quantity of im|Jerfectly oxidized albuminous
products, whose presence is due to the fact that the liver does not per-
fectly perform its fuDCtluns, and also that the products resulting fn>m tlw

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.
From the ctTcct* of repeated congestions, and of the irritation causi^I
by the ]ihsmii^ i;f alcohol throuj^h the branuhcA of the ]>orta) vein during
dij^vstion, there re^mlt^ a |>ermanent inflammatory state of the conitective
tiMiie iu eonlact with the vascular walla. Around the interlobular ves-
sels, in tlie prismatic spaces which separate the lobulea, ibere are now
secnarcas of tissue neb in nhitecorpuaclos; this tissue ia continued around
t)jc entire lobule. This alteration takes place at tbe beginning of all
the difti-'rcnl varieties of cirrhosis.
It is difficult to believe that the lesions of all cirrhotic livers foUov
the aamc rc;;nlur courte. In & niunber of casvs tlie liver is smooth apon
its surface {fifpadfU ylal-ra of Klebs), and is cither hypenrupfaicd or

But these lar^e granulations, which to the unaided eye npf}ear hoiuo-

liepatic lobules, which have their connective tissue almost normal, while
the entire group is surrounded by a thick fibrous envelope.

the lobules is very resisting; it is impossible to tear the hepatic )iart>n-

that the organ may bo siretthed witbant ruptnrin;^. Connective tissue
fibres predoniinale in the new tissue, and between these fibres no collec-
tions of embryonic cells are found. All the cellular elements interposed
between the fasciculi of fibres arc flat or stellate and provided with a
flat nucleus. The liver is usually arnemic; its lobules arc fatty infil-

In the cirrho.*ed jHirtionR, in Bome place» there exists a true eavemona
tissne, the irregular lanunne of which are, like the capillaries, dilated and
filled with blood. The walls of those vascular sinu<!es are formed by
the no>ghhonn>; connective tissue and their intenml Hiirfacc is lined by ft
liiver of flat cells. The same lesion is foinvi also in a number of hepatic

portal vein and hepatic artery are permeable t« Mood, while, on the con-
trary, the circiilttlion in the capiliariea of tho lobules is impeded ; the
pressure of the blood dilates the smallest vessels which remain permeable,
(«specialty when they arc seated in a soft embryonic tissue. It is under
.Buch conditions and in sucli a tissue that vavcnious angioniata of tlis
liver are developed.

sinuaes which ai-e channelled iu the indurated connective tissue, the

the interlobular branches of the portal vein there are no contractile or
elastic elements to force the blood into the capillaries of the lobules ;
their external and middle coats are wantin;;, there remains only a layer
of endothelial cells lining a canal which is neither contractile nor

intra-lobular biliary vemieU. Tborvfore we believe that in cirrhosis, while
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

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

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

This amyloid degeneration commences in the liver, in the terminal

TuhereltE. — Tubercle granules are very common and often very nume-
rous in the liver of patients who have succumbed to an acute miliary
tul>erculoMS. These granules are so minute that they arc seen with dif-
ficullv by the naked eye. The liver is an»mtc. yellowish, and it is
oidy Ml examinin» it attentively in a favorable li;;bt that the small semi-
transparent f;niins are seen between the lobules, (jranules locfited in
tlic capsule or upon the periwneum aR- more easily disliii^nished. The
miliary (granules in the substance of the liver are seated in the connect-
ive lisisue which aceowpanies tho portid vesseU. Cpo» a thiu section,
these vessels arc found either in the centre or near the penphery of tlie
granule, 'i'liey are accompanied by a new fonnation of embryonal tw-

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
scst«d near the ityloru:* presented ii[>on ltd peritoneal flurfaco lines or
tortuous conia of tlie siee of n crow or gooM (|uill, which were nothing

location. Tho trunk of the portal vein ami all of itit afferent branches

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

inner tunic ju-oliferates, and the cancerous tiifjtne project* more luul more

under the influence of tlie blood, and beooaie ilt^tnched and form ;;eiiuinc
emiioli. These cancemiuendioti, arretted in an interlobular branch, may
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
liy IJemian autlio», the capillaries uf the hepatic lolinlcs were filled
with the cclltdar clenicnU of the tumor (radiated cHrciiioriia of Itind-
fleiach).
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

healthy. Btit the network of hepatic cells was replaced by neats of
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

Yd cnlculi ilo noi nlwayi», or usually, occasion irritation of its int)«ou«
m«nihran«; in old women, with wliom cnlculi arc tto frc<|iicnt, tticinten«1
m«tiilirati« of llie gall-bladder is often inlnct. At other tiiDM, tl is in-
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-
rii^ in cholera, typhoid fever, and puruletit infection.
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
svpparative inflammation. It is ea^ly understood that the (edematous
swelling of the ampulla of Vat«r and conm'ciive liwuio around the
common biliary duct at its duodenal exlremiiy, may he an ohxtAcle to
the flow of bile ca[>ahle of producing jaundice, h is seldom that an
autopsy demon.^trati:* this lesion in simple icterus, hut the oK^crvations
by Virohow and Vulpian are such as to leave no doubts as to the pailio-

Till- tiiiiKir» devoloF>ed in the mucous membrane of the gall-bladder are
carcinomata or c vlindTicJil-celled epitheliomaia. The history of carcinoma
of the ^ll-btadaer is relatively of recent date, yet it is not a very un-
usual aflectioD. It may be i>r!mary or secondary; in the latter case it
follows a carcinoma of the liver. stoma,ch. intestine, or uei^hboriu);
glands. Primary carcinoma of the sull-hladdcr Is most frct|ucnlly a col-
loid carcinoma ; at ntber times it hn» the appearance of encephaloid, and
more rarely it beloiifç» to scirrhus. Its Anatomical form is very similar
to that occtirring in the intestine. Generally, indifd fourteen lime» in
fineen, the j^all-bladiler contains one or more calculi ; the fewer in num-
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.
The surface of the gall-Uadder at the diseased point h uneven and jrran.
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
Sfsion of the mucous niembniTic and submucous connective tissue may
CXttnd to the muscular tissue, which latter is ulnays somewhat <cdema-
tout and hypertrophied. Tlic cavity of the ^all-j^ladder is ^enerulty
incrcACcd, but may be diminished. The timior ff'iuently extends into
tlie cystic duel ami common biliary duct, the mucous mcad>ranc of which
is infiltrated, and the calibre coiitriictcd. occasioning rvtvntion of bile in

in it» »ubsei|ucut developniL-nt, there are found upon the surface of the
peritoneum large eelU with iar;^ nuclei ami enormouji nucleoli, which are

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-

' ftppenduj;u9.
At first it is usually seen a^ a ditfused nodular tbtckening of the con-
nective tisane of the peritoneal covering of the diseased organ. In a
caroinoniu of the stoinaeU, the gastric peritoneum shows eitlier nodulei^ of
a similar nature or a diH'nse infiltration ; generally, the lympli ve«Mls oFa
veins jiroceeding from the tumor of the stomach, and passing to iht
liver or neighboring lymphatic ;;l;nids, may he seen ramifying under the
peritoneum at the sent of the lesion. An invasion of the«ntir« serous
membrane by the carcinoma follows ; it is seen covered with numerous
■ granulations or sm»1] tninoi-s, varying in sine from a millet seed to
pa small pea or larmier. The smallest of the»e granulntions. especially
when the primary carcinom» is a scirrlnw, to the unaided eye veri '

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

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-

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*
terminH. Wc have seen one example in senile marasmus. It is proh-

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.
St/philitir ffummala are very seldom met with. Klebs baa seen
gunim.itu in the pancreas of a fuutiu of six months which had syphilitic
legions «f till- lungs, liver, and kidneys.

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

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,
• which do not anastomose with those formed hv the neigbborin^ arteries.
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
bodies.
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,
which passes through their centre, or near their jieriphery, and which
eends into their interior small arterioles and a network of capillaries.
These corpuscles consist of a reticulated tissiie. similar to that seen in
the closed follicles of the intestine. Tho meshes of this tissue are coD'
nectol with the sheath of the arterioles and capillurics; the mesboB at

filaioentA (intervawular cords of Itillrotb). The veina have no distinct
«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

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-
tiona ; but the ^tnictiire of it« ImheculiB ami uHp>u1e, whieh contain
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
its cutsnrface is hrown in color and not much coD|{est*-d. Mivrotcoi
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
intlammation, since there is,as an eiittenttul phenomenon, a de:»truction of
tlie red corpuscles which are taken ii|> hy the lyiu)ih celLi.
In very intense con^restiona due to iuleriuitleni fever and typhoid fever,
there arc also found true licmurrlia^ic foci, and in many eases ni|>Utre« of
the spleen. In typhoid fewr soin(.-titues splenic infurcti are met with.
A chn>iiic coiigujttioii is alway» ohsened in diseases of the liver ae-
cam^iaiiieil nith interference of the portal cinuilation, and i» disease* of
tlie heart with iihslrnciion to the venou--* circulation. Thfl pr^S'ture of
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

there are seen u|>on the deep rod surface fibrous trabeculae and vessels
much more distinct than nonnat. The truboculio are thickened and have
a greater number of connective-tissue fihrc^s, than in the normal state. The

IxTHKHTiTr Ki. Si'i.KN'iTis. — Ohronic conge^ition^ of the aploen terminate,
as above stated, in a new formation of connoclivo tiaaue, which may he
considered a^ indicative of an inflamuialton or alow irritation similar to
that of cirrhoiii of the liver or interaiitiat paaunir>ma. This lotion is seen
in a more advauued and intense di'^rco in m ilarl'il •■i(:hfx-iit than in any
other disease. The spleen of porsoiw who die with Ihi* cachexia varies
very intwh in appeantnce. Sometimes it i» red or pink upon section, or it
nay be of a brown or slate color, and the trabconUw as well lu the sjilenio
p may be dark broirn. The diiTerencf>i in color depend upon the
lint of pigment contained in the conuective tîasue aui in the blool of
the spleen. An aimnsi constant lesion in intermittent fever which has
lasted for some time is a fibrous thickening and induration of the eapanle,
which is also covered upon its surface by inflammatory productions.
These consist of prointnont. very dense, frcquenily cartilago-likc granula-
tions, and of (ibriHar-like vegetations or fibrous floating false ntembranes.
The false nienibrunit» are vascular, while the fat granulation* forming small
fibn)mAtu with l»iniii»U-d layers (see p. 92) are non-vascular or only have
very ffw ve.«eU. Ttiesijie of the spleen i* nlmo^t alway» incren^od. A
Ïigmented spleen may reach 20 to ^■> cetitimelre-i in its largest diameter,
hew spleens are indurated, but not to such a degree as is a eirrhotio
liver. Oq examination of the pulp obtained by scraping from a red or
pink spleen, there are found a amitll number ot lymph cells containing
pigmentgmnules: ina spleen iniuratei and pigmsnted there are found
many lymph cells inSttrated with the pigment granules. These gran-
ules nri!< cither small, brown and brilliimt when they aro cxaniin?d with
higli power, or they are large and dark, or perfectly black. They are
contained in thi? lymph cell^, but are also sometimes free in the blood.
The lymph c«lls gijnerally bave only one nucleus. Tlie large endothe-

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
aplcen, particularly in cirrhosis, terminale in induration ukI piginct)tatio|^^|

and constant in inalarinl cachexia, and it is in mia:<m^tic infection that
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
formation of connective tissue upon its peritoneal snrfaco. nie folds of
peritoneum fonning the gastro-splcuic omentum, tho pbreno-<liapKrag-

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

communicates with the splenic vein, and, finally, it may work iu way

«re very frequently met with. This is explained by the fact of the
.ic artery having it» origin from the aorta, not far from its arch,
'mi by the absence of anastomoses between the branches of the spleme
artery. When, therefore, the aorta is atheromatous, and fragments of
fibnn enter into the brnnehes of the artery, the portion of the »iplecn
receiving its blood from the olwtrucied artery is the seat of an infarotu».
It is not possible for the circulation to be re-established by collateral
veasela. Infarcti should be carefully distinguished from metaslalic

From the cimiplelc obi*truotion of the arteries, from the coagulation
of the blood in all the vcHiielti of the altered region of the apleen, and
fnini the rciiulting necrotic sotieiiing, thiii process amy he compare<l to
tliat of ;;aiigrene. The mortification i-" owing to the ariesi of the circu-
lation of the blood. But here, as in the lircr and kidney, the mortitici-
tion occurs \vitliout any commimication with the atmosphere, and there is
no putrefactive or f;angrenuus odor. Anatumicnl lesions uf the s{dccn
com)inmble to putrid ganjEnnie may occur, but mily when a portion of
the nmrtified spleen is furroutided by the pur" fnim a peri-.*|ileiiilii<.

Ion power, appear as opaque bodies. The lyoiph cells eontuined iu the
reticulated tiasue of the spleen uit<lerf;o ca^-oiis de<;eneratioQ, while the
elements of the blood tn the vessels pass through the changes pn-viou^ly
described.
The trabuctdie of the reticulum in time exi>orienoes a molecular de-
struction, as do »I»o a uumlior of the lymph cells, and there results a )wr-
tial or extensive sofu-niug of the infarctii». and the fonnation of A pulpy
mass, in which are found granular cells and albuminoid aud fatty granules.
The infarciuit is at first awolien, later it contracts, and there is seen a

The cajiftule of the spleen i» almost always affected in this lesion.
At first it is congealed, afterwards it presents villi and vegetation*, is
thickened, becomes denser, and may even undt-r^o a kind of cakification.
Aa the infarctus softens, the fluid portion ia absorbed by the healthy
peripheral portions of splenic tissue. The loss of substance is, in pan,

Amtloi» DecKNeitATlox. — Amyloid degeneration of the spleen ia
seen iu two forms : in one, it is limited to the Malpighian corpuscles : in
the other, the aoiyloid degeneration is diRusc. In both variotie-s the
spleen is liypertrophied, sphcricnl, and of d-nighy consistence ; its capsule
in stretched, and in freijucntly thickened by new formation of connective
tifi*u« ujmii il« surfuco; its edges nre thick and niiinded.
In the w'r** mirU-ty the Malpighian corpuscles are seen, upon section,
lo he increased in sixe, ineastmitg from one to two millimetres or more iu
diameter; they are somi-transparent, conMiKtinj^ of a hyaline WiKtance,
which is colored niiili<>j,*any-red by a solution of iodine. The ap])earai)ce
of these large numerous corjutnclex resembles boiled sago grains, and the
lesion is termed a m-fc Htilten.
Sections of an amyloid spleen, colored by iodine and examined with
low power, show tJial the diseased parts are appended to the arteries,
or arranged around these vessels. The degeneration ia host studied by
staining with the violet of methylaniline, which colors the anivloid infil-
trate violet-red and the normal parts blue. (Sec p. i'^3.) 'l^ie wall of

interrupted. In very advanced amyloid infillradon there may bo foci w
suppuration.
In three cases of complete amy1(nd infiltration, that ve have recently

tliL' Hpluen is intilirated with iiumoroiis white hlood corpiHClM, and is
very notahly hypertraphied. Itnt this hypertrophy is never ho great
in splenic leucocythremia. In this form of the disease tlie spleen may
ac-iuire a diameter of twenty-five to thirty centimètres.
The increase in size is due to the hypcnro]>liy of the Malpighian cor-
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-
tion of the spleen is evidently atropiiiod from the compression exerted

small vesseU and cajnllaries which ]<ai8 through the {{granulations are
filled with ;;ramttar fibrin, lymph cells and lar;;e endothelial cell.i, and
they are obliterated, as has been mentioned under tubercles in general.
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.

which form new follicles (Billroth). The hyjiertrophy of the isolated
follicles, and the new formation of follicles is sometimes uniform through-

of the cells and of the fluid or colloid siilxtance continuing, the thyroid

In many other cjikch, t)ic capitlnry vCMelii and small arteries are
dilated ; the large arteries a1»o un<Ii'r;ro a change analogous to that seen

times incriiji(e<l in j>lacea with calcareous salts.
At other lime-i, the connective tissue of the gland Is very evidently
thickened and the gland is mostly formed of fibrous tissue, nhich prciiite^
upon the follicles and finally takes their place; this ts termed a fihrntiM

cells and connective ti^^ue of the gland has been pointed out. These
tubercles are of very unfrei[ucnt occurrence, and do not diSbr Ifota
tubercles of other organ.i.
Caroixoma. — Secondary carcinomata of the thyroid boily ai-c seldom
met with, and we know of no histological description. I'rimary tumom,
dewribcd as encephaloid cancer, are also very unfreiguent. Tlicy arc
large, and by their invasion of the neighboring connective tissue, they
liavc a tendency to project into the cavity of iho trachea and eesi>ph!igus,

A patient, in whom an 0|>itl]elioma of the (esophagus had been diagnosed
during life, presented at the aulo^Mty soft granulations infiltrated with a
milky juice, arising in the connective tissue of the neck, and projecting
under the mucous membrane of the (esophagus, which over their surface
was raised and thin. The connective tis!^uc. inRltratcd with large cells,
having large nuclei and brilliant nucleoli, resembled the tissue of an encc-
phnloid carcinoma, except that there were no regular alveoli of new forma-
tion, it being simply an infiltration of the pre-cxitting ti»s\K by large cell».
The thyroid body presented a similar alt^ralion of it» tissue which was

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

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

LMOlated cases of tumors cannot be placed under the dcjuriplion of a
^definite type; they establish the connecting tiiika between one variety

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.

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

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.
The connective tissue i» the kidney is, as everywhere elw, ]>cruMnt'''t by

tuhuk'A of the cortic.i] substance are those which are most fret(Uviitly
aflecwd. They, and the renal connective ti*»ue nW, nre swollen and
eaturatvd with urinary (liiid, when the hitter is retained in the kidney, in
consi->iuence of an obstacle situated at some [loint altm;^ iho course of
the nrinnry pasitase«. They become larger, more spherical, swollen,
and j;ramil«r (clouded swellinji), in renal conge*lion, in the first stage
of Bright'.* dÎHoa.te, and in every minaient albuminnu^ nephriti.-'. If
the elemenU are now examined in water, their nuclei are concealed by
the lino ;;ranuloâ. Ily the Addition of acetic acid, the albuminous j;ninuleii
disappear or clear up. and the nucleus of the cell appears: at tinips two
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
great numbers in si>me animals, us the d»^. Kre<)ueiiily in ol 1 jMrreons

exceptionti the pre.*ence «f fatty jtranules is patlioiopcal. Fre<(uenlly,
eiipecially when these granules exist with the c1oii<ly swelling and albu-
minouii infiltration of the cells, there is present one of the forma of a
catarrhal or albuminous nephritis, of varyin;;; intensity, which invoices
the escape of albumen into the urine. In certain poiaonings (photi|>honiB,
tutpliuric acid, arsenic, icterus, etc. ). and in some cuchexias (pulmonary
» phthisis, etc.). the ceils of the kidney may 1>c loaded with granules and
fat drops without any alhumeu having been present îii the urine.
Theae albuminous and fntty granular renal cell* may be seen in nil
parta of the kidney, but it is in the large and convoluted tubules of the
cortical substance that they are generally found. 'Wi* lesion also affects
Ilcide'? lo"p. Ill the stndght tubules of the in«dti!!.iry rays and in the

of a fatty granular change, for these are especially the excretory ducts
of the urine, but llieîr lumen is often filled with altered, spherit-nl, and
granular cells, which come from the cortical substance and are eliminated
vith the urine.

In run»! iiiHiimm^itions, indic'ritod by ihc presence of albumen in tlie

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
oolorin<^ matter. The oclU thus altered remain t» gitn or are free i»
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
granular cells.

The uriniferoiui tubules may be nniformiy dit^tended ; tfaia occura ia

kidney is the consc4ueiiLx- ; » similar distension U seen in the fir<9t aUs«

the lumen of the tubules eontniim n liyaline exiidnlion, dv^uamatCil cells,

Dri};bt's disease, there occurs either ob<itnictio» of a numWr of tubulei
by their cimtenti* which «scape with difficulty, or iutcrxtilial inflaninu-

from the urioifcroua tuhulos : from tlio same uauso a ilisicnsion of the
caraule of the glomerulus may take place.
Total obstruction and even complete atrojiliy of tlie uriniferoos tubules
ia observed in comprvssi'Mi of the kidney from witliin outwards by dis-
tension of the pelvis and cnlycei*, in the «evenil varit-tics of pyelo-
nephritis. There is aliiuist aUayM associated with thi« condition nn inter-
stitial nephritis chiiraclei-i7,ed hy tliickeuing and induration of the con-
nective tissue.
Lf$ionii of the Connectiee Tia»iK of the Kidnei/. — The connective
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-
gestion is intense and peniistenl,aM occurs in carliac diseases, uspeeiallv
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
cellular stroma of the kidney Is thickened, more rcslstiuj; tliau normal,

and the entire organ seems denser. Such is the essential lesion of
iiflpliritts in heart diseases, the con^stive and interstitial ncphrïûs caa»-

• In welt-niarkci) I{n;;h['e disease with C'.>ti;^-iition and renal inflkromo-
tion, the eonnectivv tissue pre^i-iils inllnriiiiiitl'irv te«if>iis, ufiich at lirsl

cvllular eIriuentA are «vtn in i^d! itepta between the tnbnles, and iti the
lii«ne mirroiindiiig the glomeruli. Thi» lesion in not nlway» preiient, and
it varieit in diHereut portion» of th« kiilney.
iDo thefle elentcnt^ come from a proliferation of the fitted 8at cells of
tlie connective tift^we, or are tliey while blood corpiidutea or lymph
cells? This is difficult to dotermiiie otherwise than by furmin;; a hy>
potliesia biutod upon analogy. It is possible to suppose that there oeeiirs
here ft diapedesis similar to that observed tition the peritODcal suroos
membrane. Later, when the kidney is atrophied nnd contraeted, in the
tasi stnge of Bri;^ht's ilisease. tliv embryonic ti^uc is orgaidxed, and
l>ccjmc* vi-ry fibrous and dense.
In ndvane«-d stages of l{ri;;ht'# disease, and in renal atrophy due to
chronic pyclo-iiepbriUM, ihe int4.-nititiai induration of the connective
Iti^ue reacheti its highest degree. A inw denne fibron» twiic at thi»
lime sejmrale* the atrophied seeretin^ c1emeiilc«. The fibroii.4 capsule
elo^ly adheres to the surface of the kidney, which is granular and
inammlllal«d like a cirrhotic liver.
Small metaetsttic absecsiieH, or dilTust^d giippiiration of the kidney,
should also be ascribed to a primary lesion of the circulation and con-
nective tûsuc. Consecutive to capillary emboli, or to the transportation
of putrid or fenueniin;; mntcrials by the blood, there are seen one or
Diorc red milinry wchymotic points, the centre of which *oon becomes
whitish and puriform; afterward» the entire small uni*« î» triiu^fonned
into a miliary uhsees*. During thi» proee.M the vessels «re at first
■ turgid, next ihe int«T[ubular connective ti»»ue i» infiltralvd with white
corpuscles and softened; at the same time, the epitliclini cells of the
tubules become granular ; lu soon u* tlie small »li«cess is formed, there
are found mingled together in the purifunn fluid while corjiuscles and

I The altered «lis of the eoiivôluted

lumen of the cnlar;;ed tubuU-s con-
tains hyaline costs. The cellx, how-
ever, may not retain their iiomial

bules ; and they nmy accnmnlate and
distend the uritiifttrnus tiibuleii into
the fiirm of varicoKc dtlatalionn. The
term duMpianiativo nephrilin is eiB-
ployed by .Johnson ami miit Ku^^Ii^h writers; the word is not jrooil,
since it seems to indicate that the uriniferous tubules poascM fewer cells
than in the normal state, while they are, on tlie contrary, distended by
mltered epithelium.
B I'he large number of hyaliue casta and their supposed fibrinous nature
" induced lleinliardt to compare Bright's disease to pncuinouia; and Vïp-
chow gave it the name of croupous nephritis ; but the fact that the casts
are not chemically composed «f fibrin oppose» tlie^ie views.

a fatty emulsion, with lar;^ free jimiiular corpuscles, derived from the

nective tissue lymphatic system of the kiilney, are filled with very fine
fatty };ramdcs ; the cells of the comicclivc tissue are also filled with tlic

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

seen, while the comioctive-tiswue cell* retained their blue color. The
lesions of the jimall veins of the pyimmidit are nnnlogous. and arc well

but tbU thickening by amyloid degeneration is much luatv deeideil i»
Ilenle's loofis, and particularly in tbe straight and oi>llecting tulwles. In

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-
latinous albuminuria.
Ketscb Itas reported several case» of scarlatinous nephritis, in which
the j^lomeruli, the connective tissue surrounding them, and that scpantt-
ing the eonvoluted tubides of the corticul sub«Iaiicc. were infiltnited with
BiUBomus embryonic cells or lymph corpuscles. This lesion is uecom-

arterioles is dimiiiishcd: at the same time their wall is thli-kencil by
chronic inâaiumation. The wall of the capillaries returns to the embryoitio

Such an; tbc aitatomical characters ol this disvsM!, which is slowly
i1«vclopcd, is aocompanic-i) with variable and slight albuminuria, with the
voiding of large ipmniiiie;' of urine, with litlle or no cedcina, and h gene-
rally aiMociatrd with bypcrtr(>)>hy of the left ventricle ocoasioneil by the
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
and parencbynialoq.* nephritis (large white kidney), il rnunt be remem-
bered liiat in the latter, the connective tissue i» normal, tho epithelium
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-
cbymatiiu.i nephHli:i. Now it is preciselv this ipieiti'in which dues not

the atrophy, tlie lihroiLt thickening, etc., arc well charaoterixed ; but
what changes does the kidiioy undergi> previous to these stages? This
is difficult to understand from the descripdons of autopsiées given by
writers. There is only seen at aHtop.ties one anatomical phase of the
disease, and it cannot always be said what were the preceding changea

' which di'vclojw t|uickly and tenninatett in death. At the autopsy there
is found ft 1ar;;o whito andemooth kidncr: th» intcngitv of the ti-^ionbai

if the patient had lived long enough? The pathologist who would judge

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-
tive tissue is irritated at the same time as the cells of the tubule. When
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-

limited to the ;;ciii to-urinary or^ns may therefore be recognized. In
the female renal luhca-ulosis is much more rare ; it may alxo be compli-
cated with ;;ranu)ations of the bladder and tuberculosis of the Fallopian
tubes and uterus.
t'inully, the patients usually die from a {general tuberculosis in 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

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,

connective tissue with which they are directly continuoua. This tissue
does not present much pathologieat change, in this respect diHeriug from

more connective tissue and lymph cells. An examination of the biwc of

capillaries from very slight mtclianieal cause», such as tlic effecta of

Instead of having the [lapillary form with long hair-like filaments, th«
pai^llomata may be more compact and dense ; they may be seen as single
or multiple nodules, consisting of embryonic connective tissue, forming a
compact and prominent mass upon the surface of the mucous membrane.

It is formed of connective tissue lined

throush which pass the tubes going to the

Tlio parenchymal or (glandular sub-
stance of the testicles is composed of
tabes which divide and subdivide, ana«toraosîn;î with each other, in such
a manner th;vt when a mimlior are collected together they form cones,

Chrosic Obcbitis. — There are several rarieliea of chronic inflio-
matiftu of the testicle. It may invade at the same liroe both iJie tcstiels
and epididymis, which are increased in sine. According to the descrij»-
tion of Fœrstcr, the lesion consists of an enlargement of th« Beminifcren»
cumils by the ei-lls forniing in greater iihundance than in the normal state,
niid by »ii intillration of all the cellular tissue with an inflammatory tx^
dati'iti. Tho fibrous trabecniiv are thickened ; tho testicle an<l ejiididj-
mix lire indurated and hoi<H«'llaled. Upon the cut aurfacc the thickened
filirnus irabeeulje are visible, and between them a yellow hoino<;cneow
ea^eoiis maris (rri^i-uus orckltii) is seen, in which traces of the seminifer.
ous tiiliCA are only occasionally found. 'J'liis lc«lon has some re^emblauce
to tubercaWis, with which it is frei|uently confounded. According to
Virchow, it has no connection with tuberculosis, but follows a traumatic
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
stationary and be surrounded with a fibrous or calcified eiKyattng :
brane ; or they may extend and open sjiontaneously.
By a solution of continuity, a hernia of the testicle may oocnr ea
nalljr as a spongy, vascular, awi gcaiiMUi.™^ mass, in which the altctvd
HrDROCELS. 661
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

su|ierimnosed thick fibi-oiis lavera supplied with veasels whose rupture
causes tlie ecchymoses often found in this formation. From the frictions
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
the l)n.-matoc«Io. The testicle \» geiicrnlly atrophied beneath tlie thick
layers of new membrane. An ewape of blood may also occur in a cy8t
of the conl.
InliltraiioHS of blood into the connective tiaaue of the testicle are of
anfreijiient occurrence. They sometimes, however, give rise to a hroma*
tocele within the testicle. This rare legion hiis not yet been minutely
described. With Coyne we have had the opportunity of stuiiyiug two
cases. There was a very old laree bsmatocele in the tunica vagiimlig.

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
criphery id contact with thu tiinifa albajïînea. The cysts surrounded
\>y an almost normal connective tissue, which contained a few lymph cells
between its fibres, varied in size from a pea to a hax^hnut. Smooth
muscular fibres were found in tliïs connective tissue. The Internal sur-
ce of the cystH, cither smooth or presenting viltoiiii projccbona, was lined
(ilh cells varying; in form; polygonal and Hat, cylindrical or ciliated and
able I- shaped. These several varieties of cells were found united into
ciaps in the sanw cystic cavity, I'he cells found in tîie serous or mucous
luid of the cysu resembled those lining tlio intoniat surface ; many had
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
e concludes that there is a new formation uf epithelium and of curiiivs
Ik'd nith miicouit cpit}ielium, and he proposes to call the DcopUsm »

the testicle to unite direoth- with the

of clo»e connective tis«ui'> which vxiKts at

Tlie parenchyma or glandular sub-

terminate by a free extremity or Inop. At the small end of the cone tlic

bard and contracting cicatricial tissue, compress the «xcrctory duet;
there results a narrowinj; or an entire obliteration of the duct, «nd con-
Mttuently a «upprcvaion of the function and an atrophy of one of tlie

Supjturaltve iitfiammatifm of the parenchyma of tJie testicle seldom
occurs. It ia, boweTcr, observed in trnuiDntiiimiS, beini; cither local or
general. Pus is formed in the cellular tissue, probably in the lyin[>)iatios
of the ;;lflni). Sometimes suppurative inHammatioos of the lymptiaues
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,

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

Hydrocele of the tunica vaginalis is fr^ifuouily cotoplicated cither «ith
cysts, or other varieties of hydrocolc. or with a scrotal hernia : it may
be the origin of a euppurativo or intense intiunnnntion of the tunica vagi-

of blood into the cavity of the tunica vaginalii).

hydrocele of the cord. Several cyata mav thus occur along the cord.
It happens, at timea, that an old hernial sac is obliterated, ai>d the
lon-ïation of tlie peritoneum constituting it, instead of rctnainiiij; colla|JiM _
is titled with fluid. There ihon results a dropsy of tlic hernial sac, which
should not be uonfounded with a cystic hydrocele. Cystic hydrocele of
the oord, or hydrocele of n hernial sftC, frv<|U0Dtly complicates simple
hydrocele of tlie tunica va>(inalis.
Other cysts which have been for a lou); lime confounded with (drnpl*
hydrocele, are nj'ermaCU- rtftl* (spermatic hydrocele), generally located
at the superior jiart of the testicle. These cyata, sometimes very lar^,
are filled with a turhiil Suid, containing with the living or altered sfienna-
tozoiiLs, cpiilielial cells similar to those of the iiormal spermatic canab.
The»c cysts may open into the cavity of the tanica vaginalis which is
frequently at the same time tJic scat of a hydrocele. In regard to their
mode of loi-uiation, the hyp ocbesis of a new and independent formation of
the cysts has been ndvocah^'d by Pajiet. According to the investigations

In a case of Lcberl there was a rcprmlviction of the Dc«plasm in the lym-
phatic glands of the neck and in the pleura.
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
type. Cystic sarcomata have been, up to the present, confounded with
[ malignant eysta of the testicles belonging to a group of tumom differing
in structure, nature, and prognosis. An uuatonit<-a) examinaticHti of
malignant cyst« of the testicle demonstnit^^'S thai ihey are unlike sarco-
mata. Malassex concludes from hi» invent i^tiona, that they are a pecu-
liar variety of epithelioma, and he name» them myxoid cpitheliomata.
In a large cystic sarcoma, a fibivus or .«arcomalous tissue, in places
Hpindlc celled, in other partit rounti celled, frequently baWng small
area» of cartilage disseminated through it, is interposed between tbe semi-
niferous tubes and cvsts. The cjatA vary in size from a hemp soe^l to •
bazel-nnl, and are hlled with a serous or colloid fluid. The tumor is ai
t first limited by the tunica albuginea, and there are found portion» of the

From the histologie*) descriptions, particularly that by Kcersler, tlie cviKs
appear to originate by an enlargement of the seminiferous tube»; the

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.

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
eiirfaec of the gland, penetrating Itetween tlie lobules of the testialea oa
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.

airojiliit'd, and filled by the new fonnation. In the centre of tlie
ttiinor, tbe oldest and mont diseased part, there are no truoes of the
tubes remaining. When the Himor ha« hail it» origin from tlio tronira!
part of the testicle, or from the rete tetitis, or from the oorpu.4 llijilim»-
rianum, there is always seen at tlic periphery of the growth op]>osite to
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
asido and compressed hy the now tissue. Theso tubes arc atrophied,
Kiirro\inded by new very vascular connective tissue, and they cannot be
drawn out. f he distended tunica albu^nea is intact. Later, howcvvr,
I thU tunic is invndcil by the tumor, and prc«enl« exoresccncc^ of tlio sanw
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

Tlie testicle is sometimes the eeat of dermoid cysts and cysts of fœtal

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.

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

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-

From these nutritive changes the organ is disposed to a more or less

Varcinnmit. — t'arcinoma of the ovary is eitlier primary or secondanr;
it may follow a carcinoma of tbe neck and body of the uterus, of to*
reclnnj, or of a more distant organ. Tbe new fonnation is then generally

in tha Jc^^cne ration of the ovary. We have several times seen cnormoua

typical cnccphaloid : besides tbe connective-tissue fibres, the trabeculie

the epithelial colls^ arc arnin;:ed without order in tlie cavities of this
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.

After the action of nitrate of Bilvcr, there arc seen upon the internal

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.

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 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

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

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

glamlH, or entire glands. This is a genuine discharge of exfoliated mu>

however, is not a fretiuent occurrence.

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

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

At avit»]isies it is very difficult, and fretpiently impotiaible, with tlie

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

Ulceration with its several conserjnences, eepccially gangrene of tlie

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

Mt/oinalfi are the most frequent, almoat the only, tumors which hare
their origin in the muscular wall of the uterus. They consist of fasciculi
of smooth muscular fibres, intersecting each other in every direction. A

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-

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,

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.

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-

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

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.

lo this âtnicturc exists a eccoiid layer, consisting of a tissue in wbicb the
cells are more numerous and arran;^ed concentrically to the acini, having
tbe appearance of a second membrana propria to the acini. The connec-
tive tissue nature of this layer is evident from tbe circumstance that
there is observed a gradual intorminglin^ of its tissue with tbe fibroM
trabcculiu, which form the framework of the gland.
A varying number of acini are grouped together into lobnlea. Tbe
latter are wparated from each other by more or Iv.tA thick bands of

ioiher hand, there is no further dcvclopment, except, in extremely rare
TcHw», there niity even be an atrophy ot the existing ducts. Tlie begîn-

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,
^ and the gland returns lo its embryonic state, fatly tissue being substituted

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

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.

fluid secreted during the last days
of gestation, or immediately after
labor, the colostrum, contains, in
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».

more freiiuuntly tiian the right, may aluin an enorruous sixe. The coDStst-
ence of the gland is normal, moderately firm in young girls orduring getla-
tion; when the hypertrophy has existed for some time in young women,
the gland liecome^ soft and flabby ; to palpation it gives a sensation of
lobuwa which are movable. The skin is normal, or sli^^htly ihickeneil,
but not adherent. The glands in the axilla are not enlarged. L'pou
section of the gland, tfacr« is seen a ^ray tissue, with yellowish lines or
lobnlM; but there is no juive. Microscopic examination of the tissue
hIioks an abundance of connective tissue, which i« denae around the
iobnU-s of tlie glnitd. Elastic tissue also is found, 'llie canaU and acini
of tlio gland are eitber lined, aH in the state of re«t, with nmall cclbi
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-

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

raising the skin, and extending from the ttnnor to the axillary gland. A
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
indicated the connection between the lymjihatics and the aivcoli of cann-

KnftjihahAd carcinoma forms, in the breast, tumore generally \xr^f.T
than the preceding, and {^rowing more rapidly. The skin, in time
invaded and thickened by a new formation of embryonic or eareinoniatoua

filtrated with lymph cells, and eonutininj; lur^e re)W.*U. The^e changes

rise to repeated henorrliagvoi >iC liniea CAnsideruhle. Hemorrhage may
also occur in the hard variety of carcinoma, hut i» always more frecjuent
and more abundant in the ^oft (eucephaloid) fomi.
A eeetiou of the tumor presents a i^oft, viucular, grayish-whîte tiesne,
and yields a very large (jtiantity of milky juice — posse;^inf;, in a word,
all (ho chani(-[«râ of enL-cjihaloid. The development, the extenmn to the
neighboriug tissue and to the lymphatic (glands, are the same «.* in
iFcirrhus, with this diflrereui.v only, that thu new Itssnc alnyiys has the same
ebamctors as the primary tumor.
Colloid carcinoma is not so frequent a» the preeeding varietie».
t'illmiê Ciirrinoma. — We have «everal time» aeen a tumor of the
mammary gland, which re»<niililed a carcinoma in its mode of extennon,
ita infection of the lymphatic glands, and its generalisation, but which,
however, differed from the preceding varie ties in tta histological structure.
To the unaided eye its appearance doefl not perceptibly differ from cn-
cephaloid carcinoma ; njion section there flows an abundant milky fluid,
and there are seen caviiies and cysts nhtcb arc <)uite large, measuring
OD»-lialf to two or more millimetres, which are filled wiili a milky juice,
and contain dendritic filaments. Some of these open cavities arv only
galactophorous ducts filled with vegetatiou», which may be easily detached
witli a needle. These dendritic vegetations, removed and stiuiicd with
piero-carmiiie, show under the micro«cope a very beau^ful bntuching
arrangement, 'l^ie princifial trunks divide, fonning long divided papillte,
terminating by free, elongated, or eluh-nhapod extrf milieu ; all are tra-
TorM^d by capillary vewel.*, which terminate iu loops at the extremity
of the pniùltH.-, and are «urrounded hy a very small amount of connective
tissue. They are everywhere covered with prUunatio or cylindrical cells,
fonning one or more layer»; die first layer is implanted perpendicularly
u]K>n the surface of the papillae, and Uie cylindrical cells forming it arc
pressed one against Uie other, elongated, granular, dif^tinct. and provided
with an oval nucletu. Tlie more superficial and detached cells are larger,

These tuniorii may he oonsideri-d a* ei<itiioliomala. This ojiinion is
lisaed upon their jimlmhle orijjin from tlif surfaee of the gahiei'iphorou*
canals, and from tlie shajie of the cells resembling those of the cylindrical-
celled epithelioinata. Vet the infiltration of the neighboring connective
tissue, changed into ahcoli containing large cells, resembles carcinocu
more than cylindricaUceUcd epithelioma, in which the epithelial fan&a-
tion^, when tlicy invade the connective tissue, have the form of vylindrinl
tu!jes ennliiininj regularly nrrnii;;('d cylindrical cells. For tlie^c reawiiui
ve have phiced the^e tumors ainon^ the caroinnouitn. llum-n'r, this
variety, like sevtml other mammary tnmor!«, is not yet îtalîsfactArily under-
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.
Cnlcnroo us or osteoid indurations may he met with cither in au en*
ehondronia or in nodules of fibrous tiHsuc.

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,

nition that Cohnbeim bas given of indamniation ia con-ect, there should
not be any dilfcrence anatomicivltjr between inflammation and uedema ; tf,

celts of the tissue ore also necossarjr in order to cbaracterixe the beg^n-
nin;; of the ititiammator; procèdes, œdi-ma remains distinct from inflam-
nwtion.
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,
tliere are -teen: 1st. Serotialraiiiiudationa forming an intoriitilial injection
of the derm ; 2il. Mij^raliou of white blood corpuscles and a few red
disks; yd. Dilatation of the lymphatic passages, the enlargement of
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.

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.

chronic inflammation of the skin is generally oliserved iu localities which
have been the seat of repeated œdemas. notiibly on tlie instep and around

larly Virchow. have considered it a special variity of elii s
(JÎ, rvrnt""M). It bas been described by Hardy as by| ; . '■

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-

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.

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.

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

congestive dermatitis, and, finally, the iiiHamraatovy induration of an
acne |iustiilo. Kmbryonic cells accumulate about the gland. At the
same time around the obstructed glandular orifice, there are IcMons of
the rete mucosum similar to those which accompany the dcrclopment of
tho variolous pustule ; the epidermis finally ruptures, and the glandular
contents (comcdone), batJied in tho pus of a small peri-follioular abscess,
may be «(luceisrd out by pressure. T^-rmination by induration froijuently
occurs in this lesion ; there is now produced around the ^liind a chronic
inflMnmation, in every way identical with that which is mmn around se-
baceous cyst« or wens. When the glands are closo together, as upon
the nose, there is frequently developed a kmtfrtmphif tmte. Ktch
gland is surrounded at its periphery by a none of embryonic tissue, which
gradually isoi^nixcd into fibrout> tii!«ue, while a new layer of indiS'erent

It has been seen that iiiH:imniiitlonN of the aWtn have a içrcat tcDdeocT,
in ninoy cases, to retum to the cun-fvtdvt tnmV/^, of which erysipelas is
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' '
; fibroD» fonns a nodule
SEOSNERATIVE TSFLAHUATIONS OF THE SKIM. 737
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-

only the sign.' of rapid evolution of the cells of the rote muco#um. l'île

the cells are no longer closely united toïcther, and they die before tiie

cpidermiâ continues to acciiniulate. the small peri-pilar corneous maas exca-
vates a cavity in the supcrfieial portion of the derma ; the skin now law

thrown off, but the loenlion of the intradermic cavity is marked upon the
skin by a small variola-like cicatrix.

of the skin arc numerou.'*. The coloring matter of bile nnifomly tiogas
ail the histological elements of the ti»>ue.4. In the skin it nets as an
irritant, and usually occasions small cnnge.ttive inflammatory points,
I and minute pruriginons papules. Frei)uetilly purpuric spots are also
seen; liiey arc due to the solvent action of the bile upon the corpnsclos
of the blood. Histologically, icteric pur]>ura does iK>t differ from any
other intersliliiil hemorrhafre of the skin.
The cau#c of tlie icteruid staining in cachexias (tuberculous, sstuniinc)

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
sinuses. The male acarus is smaller and is about one-tenth as numerous.
It is provided with an appendage (penis) situated between the two
posterior pairs of limbs.
Tiie female acarus impregnated and deposited upon the skin,

in the gland does oot cause &nj local cutaneous lesion. The animal ia
met with in the sebaceous glands of the face, external auditory meatus
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.

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-

oon.'U'ijuciitly a constant defi>|uamation unon the surface of the intejtii-

to the obstruction of that (<ortioii of the hair follicle above tlie orifice of
the sebaceous glands. This obstruction prevent* the regnlar j^rowUi of
die hair. It causes secondarily an irritation of tlie follicle, ei[>ecially
in the nei^hborliood of the bulb. Here the wall of tlie follicle under-

bility of ini.ttaking fat );ranulea for aporea is tlien avoided. Afterwards
the haint or ^icnles are dissociated upon a jfU^ slide, in a drop of a solu.
tion of potash, -10 in 100, or aaimoiiia. The tatter is less r«pid in ii«
nctirin, but ia preferable. The dissociation being accomplished in tbe
ammonia, the latter is allowed to ovaponttc. Tho parasite is then staiiivnl

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

emploTed ai the ]>rc3«nt lime by cxporioiiced liUtolojoeU. Our object ia

and most generally applicable nictliods of prcMnin;; ami hardening tî*-

for dcienee ino^t valuable pathological 8]>ccim«n», and of profiling by nn
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

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.]
