not encapsuled. They generally originate in 
connection with fat, as in the subcutaneous 
connective tissue, the tissue surrounding the 
mammary gland and the synovial fringes; or 
they may arise in the submucous and subserous 
and other tissues ; and occasionally they are 
pedunculated. They undergo calcareous and 
other degenerations, and may become gangrenous 
from strangulation of the pedicle. The fat-cells 
of a lipoma are larger and better supplied with 
blood-vessels than those of natural adipose 
tissue ; intermingled with them are patches 
consisting of embryonic cells ; the fat-cells some- 
times contain fat crystals.

albumin, mucin, globulin-like substances, grape 
sugar, urea, ammonium carbonate, and some- 
times lactic acid and kreatinin, calcium sulphate

times cloudy from sebaceous matter, lanugo, and 
epithelial scales. The urea is said not to be found 
until about the end of the fifth month of preg- 
nancy. It is chiefly of foetal origin, but may 
partly be derived from the maternal vessels.

uterus from mechanical injury, facilitates the 
movements of the fa3tus, and greatly assists in 
dilating the os uteri in labour. By some it is 
supposed to be swallowed by the child as nutri-

Xiithae'mia. (Ai6o's, a stone; alfia, 
blood.) Murchison's term for the condition in 
which lithic or uric acid is in excess in the blood. 
It may result from excessive use of albuminoid 
matters beyond the capacity of the body to con- 
vert them, or from the defective power of the 
oxidation processes, whereby uric acid is formed 
instead of urea, the lower form of oxidation 
instead of the higher. This pathology is now 
doubted, inasmuch as uric acid is not the 
necessary antecedent of urea. The condition is 
chiefly found in those who live well and take 
little exercise. The digestive organs are dis- 
turbed, there is acidity or pyrosis, indolent or 
relaxed bowels, ofli'ensive or light-coloured 
motions and piles, high-coloured and acid urine, 
depositing uric acid and urates; headache and 
mental irritability and depression, giddiness and 
singing in the ears occur, and there is frequently 
palpitation and an irregular or intermitting 
pulse.

name. Since then it has been shown to exist 
generally in plants and animals.

given by Bigelow to his operation of rapid 
lithotrity with evacuation of the fragments 
of stone. In this operation large and heavy 
lithotrites are employed which break up the stone 
so completely that it readily passes through a 
full-sized catheter. The operation is continued 
until all the fragments have been removed. The 
fragments are drawn out of the bladder by an 
evacuator, or wash-bottle, consisting essentially 
of a strong india-rubber bottle filled with an 
antiseptic solution and connected by tubing with 
the catheter which has been introduced into the 
bladder after withdrawing the lithotiite. The 
contents of the bottle are squeezed into the 
bladder, and the bottle during its expansion 
sucks back the fluid and with it such fragments 
of stone as are small enough to pass along the 
catheter. After the calculus has been broken up 
its further comminution is efl^ected by lithotrites 
of smaller size than that first employed. The 
operation may last over an hour.

bladder to withdraw a stone. The term properly 
signifies stone-cutting, and, according to Littre, 
has come to its present meaning by the misin-

speaks of Ammonius of Alexandria as surnamed 
Ai6oTo/i09, not because he cut for stone, but be- 
cause he had invented an instrument for cutting 
the stone in pieces in the bladder when it was

its removal. The operation of cutting into the 
bladder through the perineum, however named, 
was practised long before the time of Celsus by 
the Hindoos. The mode adopted was the cutting 
on the gripe or apparatus minor, when the stone 
was hooked by the fingers in the rectum, pressed 
into the perinseum, cut down upon, and extracted 
by the efforts of the fingers or by means of some 
instrument. The next advance was not made 
till the beginning of the sixteenth century, when 
the itinerarium or grooved staff was used to guide 
the knife into the urethra which was opened, and 
the neck of the bladder dilated. At the end of 
the sixteenth century L., supra-pubic, was de- 
scribed, but not practised till the beginning of 
the eighteenth. The form of the incision in the 
apparatus minor varied with different operators 
till quite at the end of the seventeenth century 
Jacques Baulot, or Frere Jacques, devised and 
practised the lateral operation. He described it 
in 1702. Rau, in Holland, probably adopted it ; 
and early in the same century Cheselden per- 
fected the operation, and in all its essential 
details it is still practised as L., lateral. 

Jt., Al'Iarton's operation of. See 
Allarton's operation. 

Ii., bllat'eral. An operation introduced 
by Dupuytren. A curved incision, with its con- 
cavity downwards, is carried across the perineum 
half an inch above the anus. The urethra is 
opened on a median-grooved staff, and a double 
Uthotome cache is passed into the wound so as to 
divide the two lateral lobes of the prostate.

(George Buchanan, of Glasgow.) Median 
lithotomy in which a rectangular staff is em- 
ployed.

The Apparatus minor, so called because Celsus 
gave the first very accurate description of it. 

It,, cen'tral. Same as L., median. 

Jt., Cor'radi's metb'od. {Corradi, an 
Italian surgeon of the present time.) The use 
of a sound having a deep groove at its curved 
end which conceals a sharp-pointed dart, which 
can be caused, by pressure on a rod when the 
sound has reached the bladder, to project back- 
wards and penetrate the membranous urethra and 
perinteum ; the dart is grooved to serve as a 
guide to the bistoury. 

Ii., ex'tra-vesi'cal. (L. extra, on the 
outside; vesica, \hid bladder.) The cutting into 
a cavity outside the bladder which contains a 
stone, for the purpose of removing it. Such a 
stone may sometimes be found in the track of a 
vesical fistula. 

Ii., talgrb. Same as X., supra-pubic. 



LITHOTOMY. 



Xi., bypogras'trlCi {'Yiroyaa-Tpiov, the 
lower belly.) Saiiiu as Z., siipra-jiitbic. 

K. knife. The knife used to cut into the 
hladilcr in £., lateral. Tliere are many forms, 
some with a straight cutting edge, others with a 
bulging edge like a scalpel ; some cutting to the 
point, as Brodie's and Listen's knife, others 
with a blunt or beaked point, as Key's and 
Thom{)son's knife. 

Xi., lat'eral. (L. lateralis, belonging to 
the side. F. litliotomie laterale ; G. Seiten- 
steinschnitt.) The cutting operation ordinarily 
performed for the removal of a vesical calculus. 
After passing a staff grooved laterally, the incision 
is carried obliquely along the left side of the raphe 
and the anus, through the various structures in 
the perineum, until the membranous portion of 
the urethra is opened and the point of the knife, 
or of the gorget, lies in the groove of the staff. 
The direction of the cutting surface of the knife 
is then slightly altered to the right of the 
operator, and as it is pushed along the staff into 
the bladder, the anterior part of the prostate, 
with its sheath, a few fibres of the levator ani, 
and the neck of the bladder are successively 
divided. The calculus is withdrawn by means 
of forceps, or a scoop, through the opening thus 
made. Sir William Fergusson modified the 
operation by making the external incision lunated 
so as almost to encircle the anus. 

This operation was apparently first described 
by Jacques Baulot, otherwise Frere Jacques, at 
the end of the seventeenth century, and practised 
by him in 1702; but it was brought to a state of 
scientific perfection by the great surgeon of St. 
Thomas's Hospital in London, Cheselden, soon 
afterwards ; and since his time no essential 
change has been made in the operation. 

Ii., lithontrip'tic. (Ai6os, a stone ; 
Tpi(iu>, to rub down.) Malgaigne's term for the 
removal of the fragments of a stone by a small 
perineal section after it has been broken up by 
the lithotrite. 

Jt., IVIa'rian. The older form of median 
lithotomy, so called from Marianus Sanctus. 
This operation is known, from the number of 
instruments required for its performance, as 
Apparatus major. It was invented by Johannes 
de Eomanis and Battista da Eapallo in the be- 
ginning of the sixteenth century, and first made 
public by Marianus Sanctus, their pupil, in 1524. 

Ii., me'dian. (L. niediiis, middle.) This 
form is performed by first introducing into the 
bladder a staff broadly grooved along its convex 
surface. A straight knife is then entered in the 
middle line of the perineum half an inch above 
the anus, and is pushed on through the several 
structures until its point becomes engaged in 
the groove of the staff. The membranous urethra 
is then incised and the wound enlarged as the 
knife is withdrawn, and then a director is passed 
along the staff into the bladder. The staff' itself 
is next withdrawn, and the finger is employed to 
dilate the prostate to a size sufficient tvr the 
passage of the calculus when seized by the forceps. 
The median oi)eration was first performed bv 
Manzoni, of Verona ; and in its present form was 
devised by Allarton. See Allartons operation. 

If., me'dio-bilat'eral. (L. onedius ; bis, 
twice ; lat< ralis, belonging to the side.) A 
combination of the median and bilateral opera- 
tions which has been recoiiimcndid by Civiale. 
A median-grooved staff" is einijluxcd ; a vertical 
incision, Lo inch long, is made in the raphe nearly 



to the anus, and carried to the membranous part 
of the urethra; the double-bladed lithotome, or 
the bilateral gorget, is now introduced and each 
lateral lobe of the prostate divided. 

£., me'dio-Iat'eral. (L. medius ; late- 
ralis.) A furm devised by Raynaud, in which 
the perineal incision is in the middle line and 
the j)rostatic incision is made laterally. 

Henry Lee's medio-lateral operation is the 
same as Nelaton's L., precreetal. 

£., perine'al. {ncpivtov, the space be- 
tween the anus and the scrotum.) The removal 
of a stone from the bladder through an artificial 
opening in the perineum, such as is made in L., 
lateral, L., median, and other forms. 

Ii., praerec'tal. (L. pree, in front of; 
rectum.) The form devised by Nelaton to avoid 
wounding the bulb of the urethra. A staff 
having been introduced, the operator passes his 
left forefinger into the anus to find the apex of 
the prostate, he then makes a curved incision in 
front of the anus and from its centre a short 
vertical incision up the raphe, he then dissects 
the anterior wall of the rectum from the bulb, 
punctures the membranous urethra just in front 
of the prostate, which he divides with the double- 
bladed lithotome. 

Ii., quadrilat'eral. (L. quadrum, a 
square; from quattuur, four; latus, a side.) 
Vidal de Cassis's modification of L., bilateral, in 
which four incisions are made into the prostate. 

Ii., rec'tal. (L. rectum, the gut of that 
name.) The removal of a urinary calculus by 
means of an opening made into the bladder 
through the rectum. See L., recto-vesical, and 
£., recto-prostatic, lateral. 

Ii., recto-perine'al. (L. rectum ; Gr. 
TTipivtoi, the space between the anus and scro- 
tum.) The same as L., recto-vesical. 

Ii., rec'to-prostat'Ic, lat'eral. (L. 
rectum; j^rostate gland; lateralis, belonging to 
the side.) Schafl^er's term for an operation for 
the removal of stone from the bladder. A sound 
is introduced into the urethra. The anus is 
kept wide open with a dilating speculum. A 
semilunar incision, with its convexitj' down- 
wards, is made along the anterior border of the 
prostate gland, and an incision is made into it as 
in lateral lithotomy. 

Ii., rec to-ure'tliral. (L. rectum ; Gr. 
ovpnQpa, the tube by which the urine is dis- 
charged from the bladder.) The same as Z., 
recto-vesical, save that the incision does not ex- 
tend into the prostate, which is dilated to an 
extent sufficient to allow the passage of the 
forceps with the stone. 

Ii., rec'to- vesical. (L. rectum, the gut of 
that name ; vesica, the bladder.) An operation, 
suggested by Sanson, for the removal of large 
stones. The staff being in the bladder, a knife 
is passed thi-ough the walls of the rectum into 
the groove as it lies in the membranous urethra, 
in such a way as to divide the internal and 
external sphincters with a portion of the anus. 
The knife is tlien pushed on into the bladder, 
dividing the prostate. 

Also, Schiiffer's term for an operation for the 
removal of a stone from the bladder. The anus 
is widely opened by means of a dilating specu- 
lum like a Sims's duck-bill speculum, and an 
incision is made into the bladder parallel to the 
axis of the rectum, commencing at the base of 
the prostate and between the seminal ducts, and 
continued upwards to the extent necessary. 



LITHOTONY— LITIIOTRITY. 



Xi. staff. Sec Staff, Kthotomrj. 

Jm., su'pra-pu'blCi ^L. supra, above ; 
03 puhifi.) The higli operation ; it consists in 
making an incision through the abdominal wall 
above the pubes, and opening the anterior part 
of the bladder below the reflection of the peri- 
toneum. It is a method adapted for the removal 
of very large calculi, or where there is consider- 
able enlargement of the prostate. It has been 
proposed to perform the operation by means of 
the thermo-cautery. 

Tliis operation was first described by Franco 
in 1560, and then by Rosset in 1581, but it was 
first practised by Frere Come in 1758. 

Xi. tam'pon. (F. tampon, a plug.) An 
apparatus for arresting lircniorrhage after li- 
thotomy. It consists of a tube carrying a loose 
calico cover ; it is puslied into the bladder 
through the wound, the cover is stufled tightly 
with cotton wool so as to compress the bleeding 
surfaces, and there tightly secured. 

Jm. tampon, Buckston Browne's. 
(F. tampon.) An elastic tube surrounded by an 
india-rubber ball with a movable muslin cover. 
The tube being passed into the bladder through 
the wound the ball is distended with air. 

Ii., urethral, in the fe'male. {Ovpn- 
^pa, the tube by which the urine is discharged 
from tlie bladder.) A grooved statf is passed 
into the bladder, and a sharp-pointed bistoury 
guided by it is pushed through the tloor of the 
urethra, about an inch and a half from the 
meatus, the canal being divided directly down- 
wards. The stone is removed through this 
aperture. 

Ii.,ure'thral, in the male, (fivpvdpa.) 
The removal of calculi which have become 
impacted iii the urethra. It is performed by 
pushing the calculus backwards to the membra- 
nous portion of the urethra, cutting down upon 
it in the middle line, and extracting it thi'ough 
the opening. 

Ii., vagl'nal. (L. vagina, a sheath.) A 
straiglit stati' is passed into the bladder, the end 
is pressed against the anterior wall of the vagina, 
and a scalpel is pushed through the vaginal wall 
and fundus of the bladder into the groove. In 
this way the urethra is left intact. The stone is 
removed by the forceps entire or after crushing, 
and the bladder is washed free of detritus and 
clots through the urethra. 

Ii., vagri'nal, direct'. (L. vagina.) 
Consists in passing the fingers into the vagina, 
pressing up the stone against the neck of the 
bladder, and then making a transverse incision 
directly down upon the stone lying between the 
ui'ethra and symphysis pubis. 

Ii., vesl'co-vagri'nal. (L. vesica, the 
bladder; vagina.) The same as L., vaginal. 

Ii., vestib'ular opera'tion of. (L. 
vcstibulum, a fore-court.) Performed in women 
by making the incision across the centre of the 
vestibular space. 

Ziithot'ony. (AiOos; tovos, a stretching.) 
Marshall Hall's term for a mode of removing a 
stone from the bladder. A fistulous opening 
into the bladder is to be established just above 
the pubes, and then the fistula is to be dilated 
till it is capable of transmitting the stone. 

ZiithOtre'siS. (Aifos, a stone; Tpf/o-is, 
a boring through. F. lithotrese ; G. Steinzer- 
hohrimg.) The form of lithotrity in which the 
calculus is first bored through in several places 
by means of a drill.

and as Lithotrity. 

Xiithotrlp'sy. (AtSos, a stone ; Tpul/ti, 
from Tpiliu), to rub down. F. lithotripsie ; G, 
Stcinzcrmalmung .) The operation of rubbing 
down calculi in the bladder by means of an in- 
strument for tliis purpose, called a lithotriptor. 

Also, a synonym oi Lithotrity. 

Ziitho'triptic. See Lithontriptic. 

Ziithotrip'tor. (At'tJos, a stone ; rpij^w, 
to rub down. F. lithotriptcur ; ii. tStemzer- 
maimer.) An instrument for crushing or rubbing

that they may be voided with the urine. 

Also, a Lithotrite. 

Xiithotrite. (F. Uthotriteur ; from Gr. 
/\itJo9; L. tritor, a rubber; from tero, to rub. I. 
litotritore ; S. litotrifor ; G. Lithotrilor, Stein- 
zerreiber, Steinzcrmalmer.) An instrument for 
crushing stones in the bladder. The name was 
first applied by Civiale to the third part of the 
Lithotrity apparatus, Civiale's, but now it is 
used to denote the instrument which sprung out 
of his Litholabe when crushing of the stone 
without previous perforation was first attempted. 
The lithotrite is a divided steel stem bent at its 
inner extremity to form a blade or beak, consisting 
of two rods or branches, the inner of which, or 
male rod and blade, runs in the outer, or female 
rod and blade ; the outer extremity is furnished 
with a screw or other apparatus for producing 
the sliding of the rods on each other and the 
separation or approximation of tlie blades ; the 
blades are set at about right angles to the stem ; 
the male blade is the narrower and is roughened 
on its distal surface, the female blade is larger 
and is either flat or fenestrated. There are 
many varieties iu form and in detail. 

By a later improvement the male stem is 
capable of lateral movement so that the beak 
may be freed from detritus. 

Ziithotrit'ia. The same as Lithotrity. 

XiithOtrit'iC. Eelating to Lithotrity. 

Iiitlxotritor. (F. Uthotriteur ; from Gr. 
Xi'dos, a stone ; L. tritor, a rubber.) The second 
of the three pieces of the Lithotrity apparatus, 
Ciriale's. 

IiithOt'rity. (F. lithotrite; from Gr. 
\tt)os, a stone; L. tero, io break iu pieces. I. 
litotrizia; S. litotricia ; G. Lithotritie, Stein- 
zermalmnng.) A method of removing calculi from 
the bladder by crushing them into sufliciently 
small pieces to enable them to be passed by the 
urethra. The operation was brought into re- 
pute by the French sm-gcons, the chief among 
them being Civiale, during the first quarter of 
the nineteenth century, after the perforation and 
crushing of a calculus had been proposed by a 
Bavarian surgeon, Gruithuisen, and the instru- 
ments for the purpose had been described by him 
in 1813. The operation imderwent successive 
modifications until the year 1878, when Bigelow 
introduced the operation of litholapasy, which is 
gradually superseding it. In lithotrity the strong 
slender lithotrite is introduced into "the bladder 
through the in-ethra, and the stone being seized, 
it is crushed into fragments. This constitutes 
the first sitting, and it only lasts a few minutes. 
The patient is then allowed to rest for a week, 
during which time some of the smaller frag- 
ments are expelled with the ni'ine. At the 
second and subsequent sittings the fragments 
are again crushed until they are of sulficient 
size to be evacuated. The final exploration is 



LITIIOTPvYPETA— LITMUS. 



made after all the fragments are supposed to 
have been expelled ; it is conducted with a small 
lithotrite and with a moderately full bladder. 
The objections to the operation depend upon the 
repeated manipulations, upon the irritation 
caused by the crushed stone, and by the strangury 
BO often resulting from the impaction of frag- 
ments in the neck of the bladder. See its 
development Litholapaxy . 

The earliest record of any proposal for the 
crushing of a stone by means of an instrument 
passed through the urethra appears to be con- 
tained in a panegyric on the monk Theophanes, 
pronounced in the ninth century, but it is not 
clear whether the stone was contained in the 
bladder or was arrested in the urethra. In the 
twelfth century Albucasis related a mode of 
breaking up soft stones in the bladder by means 
of a delicate instrument gently introduced 
through the urethra. In the fifteenth century 
Benedetti, of Padua, described iron instruments 
for the breaking up of a vesical calculus, but 
did not recommend their use. In the sixteenth 
century Sanctorius proposed the introduction 
through the urethra of a three-bladed forceps to 
seize the stone and extract it from the bladder. 
Then in the eighteenth century two persons, a 
monk of Citeaux and Col. Martin, both suffering 
from stone in the bladder, passed into it through 
the urethra a tube carrying a stylet which ter- 
minated in a file, which could be protruded from 
the tube so as to rub down the stone. In 1813 
Gruithuisen, a Bavarian surgeon, described a 
series of cutting and crushing instruments which 
could be passed into the bladder through a 
straight, open-ended catheter, but he does not 
seem to have used them. Many other surgeons, 
Fournier de Lempdes in 1817, Civiale with 
his lithontripteur in 1818, Elderton, Amussat, 
Leroy d'Etiolles, and others, devised instruments 
for the same purpose, which were used on the 
dead body ; and in 1824 Civiale used his three- 
branched forceps, or Litholabe, with success in a 
living patient. By this instrument the stone 
was perforated in many directions, so that at last 
it was broken up by the forceps and the pieces 
could be passed with the urine. Afterwards the 
crushing of the stone was attempted without 
perforation, as in the loop instrument devised 
by Jacobson, a Danish surgeon, but the lithotrite 
as now used with curved end, and consisting of 
two limbs, one moving on or in the other, was 
developed chiefly by Weiss in England, and 
Heurteloup in France. The mechanical means 
at first used for the crushing was the blow of a 
hammer ; screw-power was used by Hodgson of 
Birmingham, in 1825, to which was added the 
rack and pinion by Sir William Fergusson in 
1834. 

Ii. appara'tus, Civ'lale's. (L. pince 
u troix hruHchts.) The instrument by means of 
which Civiale performed the first successful litho- 
trity in 1824 consisted of three pieces ; first, an 
outer tube or straight cannula or sheath ; second, 
the LitJiolabe, a steel cannula which slides within 
the outer one, and at its vesical extremity carries 
three elastic branches which widelj' expand 
when the second cannula is projected beyond the 
first, these are for the seizure and retention of 
the stone ; third, the Lithotritor, a stem of steel 
which traverses the axis of the litholabc, having 
a toothed head which perforates the stone when 
the stem is rotated by means of a drill-bow. 
Xi., perlne'al. {Tltplvio's, the space be- 



tween the anus and the scrotum.) Dolbeau's

membranous urethra by means of a median in- 
cision of the perineum on a grooved staff, dilat-

LIVE-BIRTH— LIVER. 



life. F. vivant ; I. vivo; S. vivo; G. lebend.) 
Having life ; active. 

Also, to have life. 

1m, blood. The name given to the flicker- 
ing sensation felt in the eyelids, caused by irre- 
gular fibrillary contractions of the orbicularis 
palpebrarum muscle. 

li.-for-ev'er. The Sedum telcphium. 
Ii.-long. An old name for lozenges con- 
taining rhubarb and ginger. 

Also, see Livelong. 

liive-birtll. The birth of a child is, 
according to many judicial decisions, the entire 
extrusion of a eliild from its mother, and the 
evidence of live-birth has been declared to be the 
manifestation of some certain sign of life after 
that extrusion. The manifestation may be mus- 
cular movement, the act of breathing or crving, 
the pulsation of the umbilical cord, or the beat- 
ing of the heart. 

But the circumstances of the birth may be 
such that, the child having died, the evidence of 
live-birth can only be supplied by a post-mortem 
examination. In this case the most important 
consideration is the appearance of the lungs. 
Lungs which have neitlier breathed nor been 
inflated are of a uniform and firm texture, re- 
sembling in colour and consistence the adult 
liver. Their surface is marked by slight fur- 
rows, which mark the division of the lobules. 
After respiration or inflation the edges and con- 
cave surface of the upper lobe of the right lung 
most readily admit air. The freshly developed 
air-cells take the form of brilliant vermilion 
spots, the tint becoming lighter the longer the 
lungs are preserved. The air-cells are angular, 
and are not raised above the surface of the lungs. 
In an imperfectly expanded lung they ai'e usually 
in irregular groups. But as a child may breathe 
before the head is born or before the body is 
completely expelled the aerated condition of the 
lungs is no proof of live-birth in the legal 
sense. 

Additional evidence may be obtained from the 
alterations which take place in the umbilical 
cord and the contraction of its vessels ; from the 
closure of the foramen ovale aud the ductus 
arteriosus ; and from the presence of air in the 
alimentary canal. 

Iiive-bOX. An apparatus by means of 
Avhich minute living objects may be examined 
under the microscope without injuring them, 
though their movements are restrained. It 
consists of a short piece of brass tubing fixed 
around an aperture of equal diameter in a brass 
plate and having the other end closed by a disc 
of glass ; over this is placed a tightly-fitting 
cover, consisting of a ring of brass in which is 
set a disc of thin cover glass. The object is 
placed on the thick glass, and the cover is ad- 
justed to the fitting pressure. 

Xiive'do. (!•'• livco, to be black and blue.) 
A small blui-sh-red spot in a tissue resulting 
from passive hypenvmia of the part. 
Also, another term for liver. 

Ii. calor'ica. (L. calor, heat.) The 
bluish-red or dark-blue discolouration of the skin 
often occurring in lines, or circles, or serpentine 
figures, which is seen in the skin of a person 
exposed to cold. It is a passive hypertcmia of 
the capillaries and veins. 

Ii. mecban'ica. {Mechanical.) The 
leaden-grey or bluish-black discolouration of the 
skin produced by distension of the veins and 



capillaries from mechanical compression or from 

difcct in the valves of the veins. 

Livelong". The Sedum televhiiim. 
It, or'plne. The Sedum telephium. 
liiv'er. (Slid. E. lieur; Sax. lifer. F. 
foie; l.fcijato; S. higado ; G. Leber.) A large 
abdominal viscus of a brownish red colour, 
situated below the diaphragm, in the right hy- 
pochondrium, and stretching across the epigastric 
region to the left hypochondrium; it consists of 
a large number of lobules of the same construc- 
tion ; it secretes the bile, forms glycogen, and 
takes part in the general metabolism of the 
body. 

The liver of Invertebrata is a gland developed 
from the wall of the mescnteron, or in some 
forms is a development of the yolk cells which 
remain after the formation of the mesenteron ; 
it is a digestive organ more closely allied to the 
pancreas than to the liver of Vertebrata. 

Of Vertebrata, in Pisces the liver appears 
as a diverticulum of the alimentary canal in 
Branchiostoma. In the Mysinoida it is bilobed, 
the anterior lobe being small and rounded, 
the posterior larger and elongated. In other 
fishes the liver is a relatively large single gland, 
which is either simple or with a right and left 
lobe, or with a third central lobe. It contains 
much oil. The gall-bladder is rarely absent ; 
its duct, as well as some separate hepatic ducts, 
opens into the duodenum. 

Amongst Amphibia the liver is constantly bi- 
lobed in Anoura ; in Urodela it is only incised at 
the margin, and in Gymnophiona it is divided 
into small lobes placed one before the other. 

In Keptilia the liver is large. In Ophidia it 
is often undivided. In lizards the margins are 
incised or lobulated, and in some Chelonia 
and crocodiles it is bilobed. A gall-bladder is 
usually present and closely attached to the liver, 
but in some snakes it is placed at some distance 
from it. 

In Aves the liver is large, occupying a con- 
siderable part of the anterior and median region 
of the body, reaching, in consequence of the 
absence of a diaphragm", far into the thoracic 
cavity, and embracing the apex of the heart. 
It presents right and left lobes, the right being 
much the larger, and these are often subdivided. 
A gall-bladder is sometimes present, sometimes 
absent, as in pigeons, parrots, toucans, and in 
the ostrich and cuckoo. 

In Mammalia, according to Flower, all livers 
are primarily divided by the umbilical vein into 
a right and left segment. In many, each segment 
is further divided by a right and left lateral 
fissure running from the free towards the at- 
tached border. There is thus a right and left 
central and a right and left lateral lobe, the 
former being oft^n together named the middle 
cystic or suspensory lobe. The left segment of 
the liver is rarely complicated, the right is 
marked by the groove for the gall-bladder, when 
present, tlie portal fissure, and the fissure for the 
vena cava. Between the vena cava and the 
portal fissure is a prolongation to the left, named 
the Spigelian lobe, and a pi'occss named the 
caudate lobe, which separates the right lateral 
lobe into two parts. A gall-bladder is generally 
present but sometimes absent, as in many 
Rodents, Solipeds, Iluminants, and Pachyderms. 
In Man the liver is a brown gland occupying 
the right hypochondriac, the epigastric, and 
part of the left hypochondriac regions; it is 



LIVER. 



smooth on the surface, which is covered with 
peritoneum, and presents a thick posterior and a 
thin anterior border. The upper surface is 
convex, the inferior irregularly concave, and is 
divided into two chief but unequal lobes, right 
and left, with several subsidiary lobes, de- 
scribed under the subheadings of Lobe of 
liver. Transversely it measures about 30 cm., 
or nearly 12 inches, antcro-posteriorly about 
20 cm., or about 7 inches, and its greatest 
thickness is about 7 cm., or 2| inches. Its 
specitic gravity is on the average r0572. Its 
volume is 1504 to 194-t cm. ; its weight from 
0-8 to 2"1 kilogrammes. It constitutes about 28 
per cent, of the total body weight in men, and 
2'6 per cent, in women, but varies from 2'0 to 4 per 
cent. The liver is soft and inelastic, and hence 
receives impressions from neighbouring organs, 
named, in accordance with their cause, cardiac, 
vesical, gastric, suprarenal, duodenal, and colic. 
The blood-vessels conveying blood to the liver 
are the portal vein and hepatic artery ; the 
efferent blood-vessel is the hepatic vein. The 
portal vein conducts blood from the stomach, 
intestines, and spleen to the transverse fissure 
of the liver, where, in common with the he- 
patic artery and ducts, it is surrounded by a 
sheath of connective tissue, named Glisson's 
capsule, and divides into a right and left trunk. 
Each of these gives off some vaginal branches, 
and a number of veins, named interlobular, 
which run between the lobules, and give off 
capillaries that penetrate the lobules, and con- 
stitute coUectivelj- the lobular venous plexus 
on the peripheral part of the lobule. They 
are continuous with other capillaries situated 
nearer the centre of each lobule, and named 
collectively the hepatic venous plexus, which 
unite to form the intralobular vein of each 
lobule. The intralobular veins open into the 
sublobular, and these into the hepatic vein, which 
enters the inferior vena cava at the posterior 
border of the liver. The hepatic artery divides 
like the portal vein and opens into the portal 
venous plexus. The interspaces of the capillary 
plexus are occupied with cells, the true hepatic 
cells, which contain much fat, glycogen, and 
colouring matter. They are about the QOOth of 
an inch in diameter and have no cell membrane. 
They contain one, or sometimes two, round 
nuclei, and are said to exhibit slow changes of 
form. The hepatic ducts commence by plexuses, 
the branches of which groove the cells. The 
nerves are derived from the vagus and the 
sympathetic. The liver has a capsule of two 
coats ; an investment of peritoneum and a sub- 
peritoneal coat of areolar tissue. 

The liver of man has sometimes no lobes, at 
others it is divided into many lobes, as many, 
according to Sommeriug, as twelve. Occasionally 
a small accessory liver is found. 

The term was formerly applied also to several 
chemical substances of a brownish or liver colour, 
chiefly combinations of sulphiir. 

"Im., ab'scess of. (L. abscessus ; from 
abscedo, to form an abscess. F. abces die foie ; 
G. Leber abscess.) An acute circumscribed hepa- 
titis which terminates in suppuration. It may 
be caused by local conditions, such as a blow, an 
hydatid, or a calculus ; or it may arise from 
disease in some remote part in direct venous con- 
nection with the Liver, as when it results from 
dysentery, in which case the products of the in- 
testinal ulceration are absorbed and conveyed to 



the liver by the portal vein. Purulent infection 
from any wound, or even from a diseased condi- 
tion of the bile-ducts themselves, may give rise 
to hepatic abscess. In hot countries hepatic 
abscess, or tropical abscess, may occur witnout 
visible cause, other than climate, though it is 
often associated with slight attacks of dysentery. 
An hepatic abscess may also commence as a 
diffuse inflammation of the liver substance, 
characterised by tlie blocking of the blood- 
capillaries with zoogloea, resulting from the 
multiplication of bacteria. The liver cells be- 
come disintegrated as the bacteria multiply. 
The abscesses may be multiple. The symptoms 
of an abscess of the liver are sometimes latent ; 
but often there is an initial rigor, followed by 
febrile symptoms, nausea and vomiting, fulness 
and weight or pain in the right hypochondrium 
and the right shoulder, depression of spirits and 
sweating ; there is generally increase of the area 
of hepatic dulness, with, it may be, an irregular 
outline, and not infrequently rigidity of the 
upper part of the right rectus muscle. The 
abscess may burst, or be opened hy the aspirator, 
externally, and recovery ensue ; or it may burst 
into the peritoneal, or pleural, or pericardiac 
cavity, or into the vena cava, the intestine, or the 
pelvis of the kidney, and become fatal ; or death 
may occur without any bursting of the abscess. 

Ii., abscess of, bll'iary. (F. abcis 
bUiaire dn foie.) Cornil and Ranvier's term for 
small, disseminated collections of pus which 
take origin in the interlobular bile-ducts, and 
extend into the neighbouring parenchyma and 
connective tissue. They are caused by a catar- 
rhal inflammation of the bile-ducts set up by 
small biliary concretions. They vary in size 
from that of a hemp-seed to that of a hazel-nut, 
and are filled with a bile- tinted, muco-purulent 
matter, containing granular leucocytes, cylindri- 
cal epithelium, and bile pigment. Their walls 
are formed of embryonic tissue. 

Ii., ab'scess of, bydat'id. ('Voa-rts:, a 
watery vesicle.) Suppuration in an hydatid cyst. 
See also L., abscess of. 

Im,, abscess of, pyse'mic. {Uv6v, dis- 
charge from a sore ; aiixa, blood.) Small and 
numerous, often superficial, abscesses of the liver, 
chiefly following ulceration in the track of the 
portal vein, and caused by absorption of a septic 
substance and its transmission by the portal vein 
to the liver, where probably it forms a thrombus. 
The abscesses contain a foul-smelling, greyish 
or greenish pus, with debris of liver tissue. See 
also L., abscess of. 

It., ab'scess of, tropical. The form 
which occurs in hot countries. It is usually 
situated in the right lobe, and has no limiting 
membrane or surrounding area of condensation 
or inflammation, the walls being formed of ragged 
liver-tissue ; it contains a pinkish, creamy sub- 
stance in which are found pus corpuscles, dis- 
integrated liver cells and connective tissue, and 
many red blood- corpuscles. See L., abscess of. 

Ii., ac'cessory. A detached portion of 
liver substance occasionally found attached to 
the left extremity of the organ by a fold of peri- 
toneum containing blood-vessels. 

Ii., acute' at'ropby of. Same as Z., 
atrophy of, yellow., acute. 

Ii., adeno'ma of, tu'bular. ('Acrji;, a

a framework of vascular fibrous tissue. It is 
generally secondary to similar disease in the 
digestive canal. 

Ii., albuminoid disease' of. {Albumin; 
Gr. eloos, form.) The saiuc as L., degeneration 
of, amyloid. 

Ii., alve'olar colloid of. A term given 
by Virchow to the multilocular form of hydatid 
of the liver, called Echinococcus multilocularis. 
See also Liver, hydatid of. 
Ii„ am'yloid disease' of. See L., de- 
generation of, amyloid. 

Ii., anse'mia of. ('Ai^ai/uuc, want of 
blood.) Bloodlessness of the liver ; usually 
secondary to general anosmia ; it may result, 
however, from external pressure upon the liver 
or from swelling of the liver cells. 

Xi., an^eio'ma of. {^kyyiiov, a vessel. 
G. cavern'ose Anyiom der Leber.) Erectile tu- 
mour or noevus of the liver, due to atrophy of 
the liver colls, with a varicose condition of the 
intralobular capillaries. It is usually superficial, 
forming slightly depressed blackish or purplish 
patches, consisting of irregular spaces formed by 
trabeculae of fibrous tissue, which are covered 
with tesselated epithelium ; the blood which fills 
the spaces is granular in appearance. By some 
they are supposed to arise from varicose dilata- 
tion of intralobular capillaries ; by Virchow that 
the formation of granulation is the earliest stage. 
The larger tumours are bounded by a fibrous 
capsule, whilst the smaller ones are continuous 
with the liver tissue. Angiomata are most 
frequently found in old cirrhosed livers. 

Xi., anom'alles of. ('Aytu^uaXos, irregu- 
lar.) 'The liver may be quadrangular or rounded 
instead of its usual shape ; the left lobe may be 
prolonged or absent ; it may retain more or less 
its foetal state of lobulation, or the lobes may be 
too few. The whole organ may be absent, or 
the gall-bladder may be wanting. Accessory 
livers may be found and usually in the suspensory 
ligament. The liver may be situated upon the 
left side ; it may protrude into the thorax when 
the diaphragm is defective ; or to the exterior 
from absence of the abdominal walls. It may 
become deformed as the result of disease or tight 
lacing. The organ may be displaced as a result 
of mechanical pressure acting through the dia- 
phragm, as in pneumothorax ; or it may be 
floating or movable. 

Ii., ap'oplexy of. Extravasations of 
blood into the liver substance or beneath its cap- 
sule. 

It., ar'terles of. See Hepatic artery. 
Ii., at'rophy of. {'ATpoijyia, want of 
nourishment. 1'. atropine du foie.) Morbid 
decrease in size of the Uver. It may be acute, 
as in acute yellow atrophy ; or chronic, as in 
cirrhosis. It may also occur as a senile change. 
!•., at'ropby of, cir'cuiuscrlbed. (G. 
circmnscripte Leber atrophicn.) Atrophy of a 
part of the liver by compression of exsudates and 
tumours, or by tiglit lacing (G. Schniirleber). 

Ii., at'rophy of, cyanot'ic, Klebs. The 
same as L., atrophy of, red. 

Ii., at'rophy of, from pbos'ptaorus 
poisoning'. The change whicli occurs in 
this condition commences in the cells nearest 
the periphery of the lobules, which become 
turbid, swollen, and finally disintegrated, being 
replaced, as in acute yellow atrophy, by gra- 
nulesj fat-globules, and crystals of leucin and 
tyrosin ; the connective tissue undergoes hyper- 



plasia, and the whole organ is infiltrated with 
fat. The colour of the liver is greyish-yellow ; 
haemorrhages of a rosette shape are not infre- 
quent. 'Tlie jaundice is probably caused by an 
inability of the liver to remove the biliary prin- 
ciples from the blond. 

Ii. atrophy of, pigmentary. (L. 
pigmentum, paint.) Localised atrophy affecting 
a few cells or lobules, the result of long-standing 
venous engorgement, or other sources of pressure. 
The atrophied cells usually contain many bro^vn 
or yellow pigment granules. 

Ii., at'rophy of, red. (F. atrophie rouge 
dufoie; G. rathe Leber atrophie.) Rokitansky's 
term for an atrophic form of nutmeg liver, the 
result of stasis of blood in the pulmonary veins in 
chronic hypera:mia. 

Ii., at'rophy of, simple. Decrease in 
size of the liver due to rapidly fatal starvation, 
or to old age, or to chronic disorders of nutrition. 
The margins of the liver are chiefly aS"ected. 
The atrophy is due to actual loss of liver cells. 

Ii., atrophy of, varicose. (L. varix, 
a dilated vein.) The same as atrophy from 
hyperaemia. 

Ii., atrophy of, yel'lo\7, acute'. 
(F. atrophie jaune aigue du foie; G. acute 
gelbe Leberatrophie.) An acute affection of 
the liver, characterised by rapid diminution 
in the size of the organ, with destruction 
of the hepatic cells and the elimination of 
large quantities of leucin and tyrosin by the 
urine. 'The liver is smaU, flabby, bloodless, and 
of a dull yellow or ochreous colour, with some 
dark red or purple patches. The hepatic cells 
are destroyed, granular and oily products of dis- 
integration more or less entirely replacing them, 
with rounded, flat, concentrically marked discs 
of leucin, and bundles or globules of needle- 
shaped crystals of tyrosin and crystals of xanthin. 
After obscure symptoms of loss of appetite and 
fulness in the epigastrium, there is usually 
slight jaundice, which increases, and is accom- 
panied by headache and intolerance of light, 
delirium, followed by coma, and sometimes 
convulsions, with high temperature, and then 
collapse; death usually occurs on the second, 
fourth, or fifth day. Indications of interstitial 
inflammation may be seen under the microscope 
in the form of an interlobular exudation con- 
taining round cells ; the smaller bile-ducts are 
enlarged and probably new ones are formed. 
Micrococci have been found in the earlj' stages 
of the disease. 

Ii., at'rophy of, yellow, chron'lc. A 
sj'nonym of Cirrhosis of liver.

Ii., cap'sule of. (L. capsula, a small 
box.) The delicate membrane covering the liver 
divisible structui-ally into two parts ; an outer 
serous coat consisting of a layer of epithelium 
continuous with that of the peritoneum, and an 
inner fibrous or areolar coat closely adherent to 
the gland, sending delicate septa between the 
lobules of the surface, and continuous with the 
capsule of Glisson at the transverse fissure. 

Ii., cap'sule of, inflamma'tion of. 
Same as Fenhepatitis. 

Ii.i carclno'ma of. (F. cancer du foie; 



LIVER. 



G. Leberkrebs.) Cancer occurs sometimes in a 
nodular form, the nodes beiug of large size, and 
most commonly occurring in the right lobe ; and 
sometimes as a diffuse infiltration, the whole 
organ being traversed by anastomosing fibrous 
bands, enclosing islands of new tissue ; or the 
cancerous growths may be seated in the inter- 
lobular connective tissue. Carcinoma is usually 
of the encephaloid variety, more i-arely it is 
scirrhous, colloid, or melanotic in tj-pe. In 756 
cases 422 were women, 334 men. It is most 
common between the ages of forty to sixty. It 
is very rare in the tropics. It may be primary 
but is usually secondary in formation. Cancer 
of the liver is very rare in hot countries. 

Ii., car'diac. (Kapoi'a, the heart. F.

chronic hyperajmia of cardiac origin. 

Ii., cav'ernous tu'mours of. Same as

3Ci. -cells. {F . cellules hepatiqucs ; G. Le- 
herzellen.) The cells which occupy the inter- 
stices of the network of the capillaries of the 
liver. They are yellowish, polygonal, granular 
masses of reticulated protoplasm, 1-lOOOtli of an 
inch, more or less, in diameter, without a cell- 
wall, possessing a clear spherical nucleus, some- 
times two, and one or more nucleoli, with some 
fat globules, and often granules or amorphous 
masses of glycogen ; they are connected with each 
other by an albuminous cement, in which are 
fine channels, the bile capillaries ; these latter 
are said to communicate with small vacuoles in 
the liver-cells by tine intracellular passages.

cirrhosis of, hypertrophic. 

Xi., cirrbo'sls of,bypertropb'lc. (Kip- 
/oo's, reddish-yellow ; vTrlp, above ; Tpo<pn, nou- 
rishment.) A condition of increase of, and 
change in, the connective tissue of the liver, 
which causes enlargement of the organ. Its 
cause is not known. The liver becomes very 
large and dense, the capsule becomes finely 
granular, and the connective tissue becomes 
greyish and somewhat translucent, consisting 
mainly of embryonic cells. The morbid process 
commences in the interlobular branches of the 
biliary ducts, which become dilated and distended 
with epithelium, to the destruction of the hepatic 
cells.

Xi., Cirrbo'sls of, sypbilit'ic. {Kippoi ; 
syphilis.) A congenital form of syphilitic disease 
in which the connective tissue sheath of the por- 
tal vein, to its remotest capillaries or sometimes 
only the investment of the larger veins, has 
undergone excessive growth, affecting chiefly the 
fibrous, but sometimes also the cellular, element. 
The result is first compression, then atrophy and 
granular degeneration of the liver-cells. The 
liver is large, firm, and tough, with purplish 
projecting nodules. On section it is generally 
pale in colour, with interspersed pearly-white 



patches, where the intralobular connective tissue 
is in the greatest abundance. 

Xi.-col'oured. Eeddish-brown like the

Xi., cys'tic dis'ease of. Cysts of the 
liver vary in size from that of a pin's head to 
that of an orange ; they are sometimes solitary, 
sometimes very numerous ; usually they are 
thin-walled and lined with tesselated epithe- 
lium, containing a clear straw-coloured fluid, 
and sometimes brownish colloidal masses. They 
are generally caused by distension of a bile-duct, 
or, according to some, by the vacuolation of the 
liver cells.

Im., degenera'tion of, amyloid. (L. 
degenero, to become unlike one's race ; amylum, 
starch ; Gr. eI5os, form. F. degenerescence 
amyloide du foie ; G. amyloide Entartung 
der Leber.) This disease chiefly affects the 
lobular systems. The intralobular capillaries 
are first affected bj- a kind of hyaline thick- 
ening in the endothelial layer. The hepatic 
cells are gradually compressed by this deposit, 
and finally atrophy. The change involves the 
whole liver. The lardaceous degeneration may 
be brought into view by staining with a solution 
of iodine or of methyl violet. A liver thus 
affected is uniformly increased in size. Its 
weight and specific gravity are greater. Its 
edges are rounded, and the surface is smooth. 
On section it is seen to be dry and bloodless, 
smooth and translucent. In advanced cases 
there is no distinction between the lobules, but 
in the commencement of the disease they are 
distinctly mapped out. The disease is often 
associated with fatty degeneration. It follows 
upon long- continued suppurations. 

Xi., degrenera'tion of, fat'ty. (L. de- 
genero. F. degenerescence graisseuse dufoie ; G. 
fettige Entartung der Leber.) The conversion 
of the albumin of the liver cells into fat ; it is 
often preceded by cloudy swelling of the cells, 
which become turbid and granular. The liver 
becomes wasted, the capsule wrinkled, the tissue 
paleish, and easily breaking up on pressure ; in 
some places the bile-ducts, it may be, have given 
way, and bile-stained patches are seen ; in other 
places small hsemorrhagic clots have been pro- 
duced by rupture of minute blood-vessels. It 
occurs in the course of infective, wasting, and 
exhausting diseases, in pernicious anaemia, in

It., development of. The liver appears, 
in man, about the third week of fecial life as a 
double or bilobed divertieiiluin from the anterior 
surface of that part of the ])riinitivc intestine 
which subsequently becomes the duodenum ; in 
some of the lower vertebrates it is originally 
single. The diverticula represent the two lobes 
of the liver and embrace the vitelline veins, 
which form the roots of the meatus venosus; 
they consist of hypoblast, with a mesoblastic 
investment; they speedily present a cavity, the 
primitive excretory duct, which sends branches 
into the surrounding mesoblast. Towards the 
end of the third day solid cylinders of hypoblastic 
substance arise from the walls of these branches, 
rapidly increase in number by branching, and 
unite at their extremities so as to form a solid 
network. As this is progressing blood-vessels 
form in the mesobla^it which become connected 
with the roots of the meatus venosus. The solid 
hypoblastic cylinders develop into the paren- 
chyma of the liver, consisting of hepatic cells 
and elementary hepatic ducts.

culation of the blood ; by repletion of the vena 
portas, owing to excessive absorption of fluids 
from the alimentary canal ; by all morbid con- 
ditions lowering the tone of "the vessels, such 
as febrile states of the system, gout, syphilis, and 
the like; by puncture of the fourth ventricle ; 
bj' electric stimulation of the central extremity 
of the cut vagus ; by certain injuries of the head ; 
and by the toxic influence of curare. These 
causes are modified by individual predisposition, 
by age, climate, and many other conditions. 
Congestion of the liver is characterised by en- 
largement of the liver, frequently accompanied 
with yellowness of the conjunctiva. Stasis or 
augmentation of the flow of the bile, constipa- 
tion or diarrhoea, are variable sjTnptoms. It 
may be transitory or persistent. 

Zi., byperse'mia of, ctaron'ic. ('YTr/p; 
al/xa ; L. chronicm, long-lasting.) Passive 
or venous engorgement, often called nutmeg 
liver, or central red atrophy of Virchow. The 
result of obstruction to the free passage of blood 
through the organ. The commonest causes are 
diseases of the tricuspid and mitral valves of the 
heart, cirrhosis of the lungs and emphysema. 
At an early stage of the disease the liver "is en- 
larged and full of blood, whilst the central parts 
of the lobules are dark and livid. In a more 
advanced form the liver is smaller, and its surface 
is irregularly knobbed and granular. On section 
it has a nutmeg-like appearance, the dark centre 
of each lobule contrasting with the pale peri- 
phery. When examined with the microscope 
the intralobular veins and capillaries are seen to 
be enlarged and varicose, whilst the liver cells 
are atrophied and contain many pigments. 

Ii., Iiyperae'lxila of, passive. (JT-rrip ; 
alfxa ; L. pa.jsivHs, suflering.) Same as Z., hi/- 
permmia of, chronic. 

Ii., byperae'mla of, trop'lcal. (Y-jrlp ; 
aifia.) Engorgement of the liver, due in large 
degree to exposure to a continuous high tempera- 
ture, but aided by malarial influences. It often 
ends in enlargement of the organ, and is a fre- 
quent precursor of tropical abscess. 

Ii., byperpla'sia of, nodular. {Yirip, 
in excess ; 7r\do-i?, a moulding ; L. nodiilus, 
dim. of nodus, a knot.) A tumour of the liver 
consisting of liver tissue, and, when large, sur- 
rounded by a connective-tissue capsule. The 
liver-cells of which it is composed are large, and 
in some instances have two nuclei. 

Ii., hyper'tropby of. ('Y-Trtp ; Tpo<pv,

addition of natural structure only. It is a rare 
occurrence, but sometimes occurs in diabetes, 
and is occasionally compensatory.

{'Yirip ; Tporpt'i ; al^ua, blood.) Increase in size of 
the liver from persistent hj-peraemia of the organ. 

Ii., indura'tion of. (L. induro, to make 
hard.) The hardening of the organ produced by 
increase of the connective tissue, as in cirrhosis. 

Ii., infiltration of, fatty. (F. irifiltrer, 
to creep in. F. infiltratmi graisseuse du foie ; 
G. Fettinfiltration der Leber.) A greater or less 
increase of the fat in the liver-cells, due to an 
increased supply, as in the conditions producing 
general obesity and in an excess of fat-forming 
foods; or to diminished consumption, as in 
phthisis and other lung diseases accompanied by 
emaciation. The liver is enlarged to a greater 
or less extent, smooth, and yellowish or pale in 
colour, with a tense, glistening capsule. The 



surface on section is somewhat like that of a nut- 
meg liver, the periphery of the lobules being 
pale yellow and the centre brownish red or pur- 
jilish ; but when the accumulation of fat is great 
the surface is a uniform pale yellow; droi)s of 
oil may be scraped ofl' it, and a piece of it will 
float in water. 

Im., infiltra'tlon of, leucse'mic. (F. 
infiltrcr ; Gr. Xeuko's, white ; al/na, blood.) An 
enlargement of the liver in leucocytha-mia and 
splenic ancemia, due to the deposit in the interlo- 
bular tissue of a large number of leucocytes, un- 
accompanied by stroma. The liver is swollen, 
smooth, and pale, and the lobules are separated by 
broad zones of greyish white. Sometimes nodular 
aggregations accompany the diffuse infiltration. 

Ii., infiltration of, parencbym'- 
atous. (F. iiifiltrer ; Gr. ■napiyjiifxa, the 
peculiar substance of the viscera.) A condition 
which exists when the liver is enlarged in fevers, 
erysipelas, and other acute diseases ; the Uver- 
cells are highly granular, and are affected with 
cloudy swelling. 

Ii.,inflamma'tion of. The disease termed 
Hepatitis. 

!>., inflammation of,bil'iary. Inflam- 
mation of the liver starting in the bile-ducts, 
generally in connection with the retention of 
bile and engorgement of the biliary canals. It 
is characterised by circumscribed patches infil- 
trated with bile pigment. The inflammation 
may be either plastic or purulent. See also,

extensions. See Lymphadenoma. 

Ii., lympbat'ics of. (F. lymphatiqnes 
du foie ; G. Lymphgefdsse der Leber.) Ttiese 
are superficial and deep ; the former run in the 
subperitoneal tissue, the latter accompany the 
branches of the portal and hepatic veins. 

The superficial lymphatics of the upper surface 
are divided into four groups ; those from the 
middle of the organ ascend in the falciform 
ligament, and join the anterior mediastinal 
glands ; those from the sides traverse each lateral

ligament and join the coeliac glands; those from 
the front join the lymphatics of the under sur- 
face ; and those from the back of the organ pass 
into the coronary li<,'ament and join the ghiiids 
at the upper end of the inferior vena cava. The 
superficuil lymphatics of the under surficc in 
large part, including those of the gall-bladder, 
pass with the deep lymphatics through the 
transverse fissure ; but some join the lumbar 
glands, and others the cesophageal and the coeliac 
glands. 

The deep lymphatics of the portal system pass 
out of the organ at the transverse fissure along with 
the superticial lymphatics of the under surface, 
enter the small omentum, traverse the hepatic 
glands, and join the coeliac glands ; those of the 
hepatic system join the glands around the inferior 
vena cava. The lymphatic twigs commence in 
lymph-spaces and lymph-clefts in the interior of 
the hepatic lobules between the hepatic cells, and 
between them and the capillaries ; they are con- 
nected with the network of small lymphatics in 
the interlobular connective tissue around the in- 
terlobular veins of the portal system, and with the 
perivascular lymphatics of the hepatic system. 

Ii., lymphatics of, intralobular.

capillaries, and is often secondary to melano- 
sarcoma of the choroid coat of the eye. 

X., mo'vable. {Y.foie mobile ; G. Wan-

liver from a lengthening, or an absence, of the 
ligaments which retain the liver in position. 

Ii., nerves of. (fi.Lebernerven.) Branches 
of the pneumngastric nerves, especially the left, 
and of the coeliac plexus, by means of the hepatic 
plexus. They pass into the substance of the organ 
along with the hepatic artery and its branches. 
They are composed chiefly of non-meduUated 
fibres, but contain also single, small, medul- 
lated fibres ; and, especially at their branch- 
ing, they are furnished with ganglia. They 
probably form a fine network on the minute 
capillaries, but do not come into contact with the 
liver-cells. 

Z>., nufmeg. (F. foie noix de muscade ; 
G. Muskatmtsskber.) A condition of the liver 
observed when the organ has been far a long 
time congested, in consequence of regurgitant 
valvular disease of the heart, or from chronic 
bronchitis, or other impediment to the circulation 
through the heart and lungs; the lobules are 
•whitish at their borders from fatty degeneration, 
the hepatic veins being congested make central 
red spots and streaks, and the full bile ducts 



add yellow patches, which together simulate the 
appearance of a nutmeg. See L., hypercemia of, 
chronic.

ray fungus, occasionally occurs in the liver. 

It., pigmenta'tion of. (F. pigmentation 
dufoie.) A condition occasionally seen in palu- 
dal fevers, and caused by the deposition of pig- 
ment matter from the blood; it invades the 
lobules from the periphery towards the centre. 

Ii., pulsa'tlon of. A phenomenon first 
observed by Friedreich, and usually due to re- 
gurgitation of blood into the hepatic veins, owing 
to incompetence of the tricuspid valve, and then 
generally accompanied with strong cervical pul- 
sation. An hepatic pulsation has also been ob- 
served in Basedow's disease, which was regarded 
by Lebert as arterial in origin, characterised by 
its being more feeble than venous pulsation, and 
by its being particularly observable over the 
right lobe.

face, short and painful breathing, small weak 
pulse, great pain and distension, sometimes 
vomiting, and often death from collapse or hae- 
morrhage. If the patient lives more than a day 
there may be jaundice, peritonitis may super- 
vene, and suppuration may ensue.

rhosis. Gummata may be formed, often in the 
neighbourhood of tlie suspensory ligament, the 
surface of the liver being scarred, and the peri- 
toneal coat being thickened. When the scars 
are numerous the liver may become lobulated by 
the contraction of the newly formed fibrous 
tissue. Congenital syphilis leads to cellular in- 
filtration, with subsequent formation of fibrous 
tissue, or to gumma. There maj' be lardaceous 
degeneration with considerable enlargement of 
the organ. Syphilitic diseases may produce 
ascites. See Z., cirr/iosis of, syphilitic. 

"Sm., ttarombo'sls of. {Opo/xliwa-ii, a be-

occurs especially in the course of cirrhosis. 
Thrombosis of the hepatic artery is very rare 
indeed. 

Ii., tlg:bt-lace> (G. SchniirUber.') A 
deformity of the liver consequent on wearing 
tight corsets in women. When slight there is 
only a shallow transverse furrow upon the anterior 
surface of the right, and sometimes of the left, 
lobe. When strongly marked the part below the 
groove forms almost a separate lobe, united to the 
upper mass of the liver by a bridge partlj' composed 
of atrophied gland tissue and partly of fibrous 
tissue, covered by thickened and indurated peri- 
toneum, strongly adherent to the hepatic tissue. 
The tight-lace lobe is often slightly granulated. 

Ii., tuber'culated. The condition of 
Cirrhosis of liver. 

Ii., tuberculo'sis of, cbron'lc. Nodules 
like those of miliary tuberculosis are present, 
but, the affection being more chronic, fibrous 
tissue is formed, which also contains small masses 
of tubercle ; these break down, and cavities result, 
enclosing liquid or pulpy bile-stained detritus. 

Xi., tuberculosis of, miliary. The 
commoner form of the disease ; it is usually part 
of a general tuberculosis. The liver contains a 
number of small, grey, yellow or bile- stained 
miliary nodules. The nodules when recent con- 
sist of aggregations of small cells ; they contain 
giant cells in a later stage, and finally caseate.

Ii., zones of. (L. zo7ia, a belt.) The 
three areas constituting an hepatic lobule ; the 
central area forms the Hepatic vein zone, the 
circumferential area is the I'ortal vein zone, and 
the intermediate area is the Hepatic artery zone. 
The first mentioned zone is specially the seat of 
cyanotic changes, the second of fatty degenera- 
tion, and the third of amyloid degeneration.

for the umbilical vein and for the ductus veuosus 
on the inferior and posterior surfaces of the organ. 
There is no distinction between the right and left 
lobes on the upper convex surface of the liver, but 
their limits are defined by the attachment of the 
broad ligament. The left lobe is almost entirel}' 
invested with peritoneum ; its upper surface is 
in contact with the diaphragm. Its inferior sur- 
face presents an impression posteriorly and to 
the left, corresponding to the stomach, and a 
prominence named the tuber omcntale more 
anteriorly and to the right.

A Genus of the Nat. Order Lobeliacece. 

The pharmacopoeial name, B. Ph., U.S. Ph. 
(F. herbe de lobelie enflee ; G. Lobelienkraut), of 
the herb L. inflata. Its odour is slight, and its 
taste after some time burning. It owes its 
properties chiefly to Lobelin. Taken internally 
it causes, in small doses, a sensation of heat in the 
oesophagus, stomach and intestines; in larger 
doses, vomiting, headache, sweating, giddiness 
and prostration, which may pass into convulsions 
and coma. Death results from paralysis of the 
respiratory centre. Small doses first raise and 
then depress the blood pressure ; large doses 
paralyse the vasomotor centre and the peripheral 
vagi. It is chiefly employed as a remedy in 
spasmodic asthma and in chronic bronchitis with 
spasm.

tile, organic base obtained by Proctor, after 
recognition by Calhoun, from the Lobelia injlata, 
by macerating the herb in alcohol, previously 
prepared with sulphuric acid and powdered 
caustic lime. It is an oily, viscid, brownish-red, 
transparent fluid with a strong alkaline reaction, 
especially in a state of solution, and a pungent 
tobacco-like taste. It dissolves in water, alcohol, 
ether, chloroform, carbon bisulphide, petroleum, 
and benzol. It becomes resinous in the air, and 
is destroyed at a temperature of 100° C. In the 
plant it is combined with lobelianic acid. It 
forms crystalline combinations with acids. The 
solution of lobelin is precipitated by tannic, but 
not by gallic, acid. It causes contraction of the 
pupil, and taken internally in minute doses 
exercises on the human frame all the marked 
and disagreeable consequences of a large dose of 
the plant, and is therefore a virulent poison, 
producing death by paralysis of respiration. It 
has been used in asthma, in angina pectoris, 
spasmodic coughs, epilepsy and chorea. Its 
power as a narcotic is doubtful.

chronic poisoning, in which the action of the 
nervous and muscular system becomes gradually 
obstructed until complete exhaustion occurs. 
The eating of Loco-weed, Astragalus crotalaria, 
the A. Hornii, and A. lentiginosus, is supposed 
to be the cause of the distemper ; and also in 
Colorado of the Qjci/tropis Lamberti, and in

LOCOMOTIVE-LOCUS. 



Xi. of heart. (F. locomotion dn cceur.) 
The geneial movement, of forwurd projection 
which results from the sudden recoil of the organ 
at the moment of s3'stole, and caused, according 
to Hildes^heim, bj' the propulsion of the blood 
into the aorta and pulmonary artery. 

X., or'i^ans of. (F. apparcil dc la loco- 
motion ; G. Locomotionsorgune.) The organs 
by means of which animals effect a change of 
place ; they vary greatly. In the lowest forms, 
as in the Amoeba and its allies, the protoplasm 
of which the animal is composed thrusts out 
processes or pscudopodia, in one or more direc- 
tions; into this the mass of the body streams 
and gradually creeps along. In many Infusoria, 
in Clenophora, in the young of some Coelen- 
terata and Echinodermata, and in the larva) of 
some Mollusca, the locomotive organs are the 
cilia with which the body is partially or com- 
pletely covered, and which, acting together, 
propel the animal through the water. The num- 
ber of the cilia may be reduced to one or two. 
In the Medusae locomotion is accomplished by 
the contractions of the swimming bell, which are 
effected by true muscular fibres. In the Salpidae, 
and to a certain extent in the Cephalopoda, the 
sudden contraction of a muscular sac discharges 
its contents, and like a rocket propels the animal 
forwards or backwards. In most Mollusca a 
muscular foot is present, by the progressive con- 
tractions of which slow creeping movements are 
accomplished. In Cephalopoda,besides the rocket- 
like movement above described, the suckers on 
the arras are attached to some point to which the 
muscles of the arms draw the rest of the body. 
In Pteropoda the lobes of the body execute flap- 
ping movements like the wings of birds. In 
some Acephala, as in Cardium, the sudden 
straightening of a muscular column causes the 
animal to leap a few inches. In Annelida, as 
well as in some of the lower Vermes, locomotion 
is effected by creeping movements, and by alter- 
nate bending, fixation, and extension of the 
body. Insecta, Arachnida, and Crustacea possess 
an external hard covering, or skeleton, to which 
jointed limbs containing muscles are attached, 
and locomotion is usually terrestrial and by 
movements analogous to those of walking, often 
executed with considerable rapidity. Many 
insects possess wings, which are thin mem- 
branous expansions, presenting a large surface 
to the air, and enabling the creature to traverse 
space more quickly than perhaps in any other 
mode of locomotion. 

In nearly all Vertebrata there is an internal 
skeleton consisting of a vertebral column, with 
which jointed limbs are connected. These 
with muscles form a system of levers, by 
means of which progression is accomplished ; 
sometimes by the screw-like vibration of the 
tail, as in the aquatic locomotion of fishes ; 
sometimes by the flapping movements of the 
fore-limbs, the surface of which is greatly 
extended, with little increase of weight, by 
feathers, as in the wings of birds, or by a thin 
membranous expansion between the digits, as 
in bats, by which their flight is eflected ; and 
sometimes by the alternate planting of the feet 
upon the ground, as in quadrupedal and bipedal 
progression.

body of the last dorsal vertebra, the others pass 
over the bodies of the upper four lumbar verte- 
brte. Each divides into an abdominal and a dorsal 
branch ; the former, coursing through the muscles 
of the abdominal wall, gives off branches which 
anastomose with those of its neighbours and of 
the epigastric, internal mammary, lower inter- 
costal, ilio-lumbar and circumflex iliac arteries ; 
the latter give off each a spinal branch, and then 
divide into branches to supply the muscles and 
integument of the back ; the spinal branches 
enter the spinal canal through an intervertebial 
foramen, supply the dura mater and roots of the 
nerves, and divide into two twigs ; one set, the 
vertebral, forms interlacements with its neigh- 
bours on the posterior surface of the bodies of 
the vertebrae ; the other set, the medullary, 
ramifies on the anterior and posterior surfaces of 
the spinal cord. 

The lumbar arteries occasionally take origin

the canal through the foramen above each lum- 
bar vertebra. They possess larger roots than 
the other spinal nerves, except the sacral ; when 
these are united beyond the ganglion of the pos- 
terior roots the trunk thus formed divides into 
two primary branches, anterior and posterior. 
The posterior divisions are the smaller, they 
supply the neighbouring muscles and the integu- 
ment of the gluteal region. The anterior divi- 
sions, with the exception of that of the fifth and 
part of the fourth lumbar nerve, break up into 
loops that unite to form the L. plexus. The 
fifth lumbar nerve, with a branch from the 
fourth, forms the Lumbo-sacral curd.

The lungs in man constitute two conical organs 
placed at the sides of the spinal column, and 
with the heart and large vessels which lie be- 
tween them tilling the cavity of the chest. They 
are invested by the pleura?. The right lung 
is divided into three lobes, the left into two. 
The height of the right lung on its outer sur- 
face is 271 mm. in males, 21G mm. in women; 
on the inner surface 162 mm. in men, V.io nim. 
in women. The height of the h ft lung is on its 
outer surfice 298 mm. in men, 230 mm. in 
women ; on its inner surface 17G mm. in men, 
L56 mm. in women. The antero-posterior dia- 
meter of the right lung in men is 203 mm., in 
women 176 mm.; of the left lung 176 mm. in 
men, 162 mm. in women. The transverse dia- 
meter of the right lung at the root is 95 mm. in 
men, and 85 mm. in women ; of the left lung 81 
mm. in males, and 74 mm. in females. The 
transverse diameter of the base of the right lung 
is 135 mm. in men, 122 mm. in women ; of the 
left lung 129 mm. in men, and 108 mm. in 
women. The weight of the lungs containing air 
and blood, as cleanly removed from the body, is 
1740 grammes in males, and about 1023 grammes 
in females; the right lung alone weighing about 
682 grammes in men, and 541 grammes in wo- 
men. The weight of the lungs as compared with 
that of the whole body is about 1 to 40 or 1 to 50. 
The specific gravity of the lungs containing 
some air and blood is from 0*34 to 0'74; freed 
from air, but containing some blood, r045 to 
1-056. The volume of the lungs containing no 
air varies from 793 to 1230 ccm., that of the 
right lung from 516 to 624 cub. cent., that of 
the left from 456 to 585 cub. cent. ; when ex- 
panded with air to the fullest po.ssible extent 
the volume of the right lung amounts to 5157 
cub. cent., and of the left to 4364 dm., or to- 
gether to 9521 ccm. The capacity of the whole 
chest cavity in young soldiers amounts in the 
condition of expiration to 5006 com., and in the 
condition of inspiration to 8007 ccm. These 
measurements and weights are averages. 

The lungs are essentially glands consisting of 
an aggregation of lobules or acini, each com- 
posed of air-cells, air- vesicles, or alveoli in the 
walls of the alveolar passages with their terminal 
infundibula, and having an excretory tube or 
resjiiratory bronchiole, which also contains some 
air-cells; the bronchioles unite to form the 
smallest bronchial tubes, these unite to form 
others still larger in ascending series until one 
bronchus for each lung results; the two bronchi 
join to form the trachea which, after being 
modified as a vocal organ, the larynx, opens into 
the mouth and so into the outer air. The lobules 
are connected with, and at the same time sepa- 
rated from, each other by a layer of connective 
tissue, the interlobular septa. 

The colour of the lungs is pink in infants, but 
in adults is greyer and marbled with black 
pigment. The substance of the lungs is soft, 
spongy, crepitant under pressure, capable of 
floating on water, and very elastic. The super- 
ficial area of the air-vesicles has been calculated 
to be about 90 square metres, or about 100 times 
greater than the surface of the whole body. Tlie 
number of tlie air-vesicles is estimated at 725 
millions. The chemical couiposition of the lungs 



LUNCf. 



is complex; they contain, in aJdiiiun to the 
tissues, lecithin, inosite, uric acid, guanin, 
xunthin, with various salts and much phosphoric 
acid. 

In MoUusca the Pulmnnata, represented hj" the 
snail and slug, have a simple type of lung, iu the 
form of a puhiionary sac, situated in the dorsal 
H'gion, and having a rounded external orifice on 
the right side of the body. Tlie roof is formed 
by the mouth, and presents numerous and highly 
vascular ridges ; the lloor is muscular, and over- 
lies the crop and reproductive organs. 

In Pisces there is only one order the members 
of wtiich possess lungs in addition to gills. This 
Order is the Dipnoi, examples of which are 
fiiuiul iu the Lepidosiren, Protopterus, and 
13urrainunda or Ceratudus. Here tlie lung is a 
niodification of the air-bladder of other lishes, 
and consists of a single sac, as in Ceratudus, the 
walls of which present a series ef symmetrical 
pouches, or a double sac, as in Lepidosiren and 
Protopterus, with cellular structure resembling 
that of a reptile. The rudimentary lung in 
Ceratodus has no pulmonary artery, but receives 
branches from the arteria coeliaca. In Lepido- 
siren and Protopterus it is supplied with blood 
by a true pulmonary artery. The pneumatic 
duct opens into the ventral side of the oesopha- 
gus. The lungs in fishes only act periodically, 
or in an auxiliary manner to the gills. 

In Amphibia, as well as in Ophidians and 
Saurians, the lung is a simple or double sac with 
a smooth lining near the termination of the 
trachea, but towards the posterior extremity 
more or less divided into cells. In Ophidia the 
left lung is smaller than the right, or is alto- 
gether atrophied. In the apodal Saurians the 
right lung is smaller and shorter than the left. 
In Chelonians and Crocodiles the sac is branched, 
but the branches terminate in, and are beset 
with, alveoli. 

In Aves the lungs are spongy and dark red. 
They are adherent to the wall of the thorax 
posteriorly, and present the impressions of the 
ribs ; they are only free anteriorly, and the ven- 
tral surface is covered by a pleural portion of the 
peritoneum. The trachea terminates in bronchi, 
which give off brunches, the walls of which are 
alveolated. The lungs of birds are connected 
with tbin-walled sacs which are variously dis- 
tributed in the thorax, abdomen, and pelvis, 
and with the medullary cavities of the long 
bones, which aid in the aeration of the blood 
and contribute to the relatively light bodies of 
birds. 

In Mammals the general arrangement is the 
same as in man. In many Edentata the lungs 
have no lobes, but as a rule both lungs have 
lobes, the right three or four, and the left only 
two. In Carnivora and Eodentia there is an 
infracardiac lobe, which lies in a special pouch 
of the pleura between the pericardium and the 
diaphragm. 

!■., abla'tion of. (L. ablatus, part, of 
aufero, to take away.) See L., excision of. 

Ii., ab'scess of. (F. abccs du poumon ; G. 
Lungenabscess, Ltmyengeschtviir.') A circum- 
scribed suppuration in the lung tissue. It is a 
rare event, but may be a result of pneumonia, 
or of pulmonary apoplexy, or of circumscribed 
gangrene ; infective abscesses, generally nu- 
merous and of small size, may be the result of 
pya:uiic or septicajmic contamination. Suppura- 
tion may also occur in the lung by the opeuiug 



of an cmpjema, or of a suppurating bronchial 
gland, into its substance, and so into a bronchial 
tube ; and also by the perforation of an hepatic 
abscess througli the diaphragm and into the 
pulmonary tissue. A pulmonary abscess may 
ojien into a bronchial tube and its contents be 
coughed up, and partial or complete recovery 
may ensue. 

Ii., ab'scess of, perforating-. (L. 
pcrfuro, to bore tluough.) An fmj)3a ma, or an 
abscess of the lung, which opens into a bron- 
chial tube.

with seeds.) Ttic same as L.s, lobules oj. 

Ii., air-cells of. (F. vhicuhs pulmo- 
naircs, (devolve du jjo union ; G. LuiKjotblaachcn, 
Luflzcllen der Lungcn, Lujibliiiclicn der 
Lungen.) The air-cells or alveoli of tlie lung 
are hemispherical, or polygonal, wide-mouthed 
saccules or depressions on the walls of tlie 
iilveolar passages, and the iufundibula. They 
are about 250 fx in diameter, and consist of 
a thin wall of slightly fibrillated connective 
tissue, and a few corpuscles surrounded by 
many, often bifurcated, elastic fibres, with an 
intermixture of non- striped, muscular fibre- 
cells ; they are lined by large, transparent, 
thin, iri'egularly-polj'goual, placoid scales or 
squames, which are probably non-nuileated, 
and by a few small, flat, irregularly-poly- 
gonal nucleated cells lying in groups of two 
or three between the others and in the inter- 
stices of the capillaries. In the walls is a fine 
basket-shaped plexus of capillary blood-vessels 
in single line, lying immediately under the 
epithelial lining, communicating with those of 
neighbouring air-cells and connected on the one 
hand with branches of the pulmonary artery, and 
on the other with branches of the pulmonary vein. 
The epithelial cells are united to each other by 
a cement substance in which are minute stomaia 
which open into a system of lacunar and lymph- 
canaliculi which exists in the walls of the 
air-cells, and from which arise the perivas- 
cular lymphatic vessels which accoaipany the 
pulmonary blood-vessels. The air-cells gene- 
rally contain some leucocytes which carry away, 
through the stomata, into the lymphatics foreign 
bodies, such as carbon particles, mucous cor- 
puscles and other substances which have found 
their way into the air-cells. 

The presence of muscular tissue has of late 
years been doubted by Henle and others.

Schultze's term for the divisions and sub- 
divisions of the respiratory bronchioles, having 
on their walls the air-cells or alveoli and ter- 
minating in, and giving ofl' laterally, the iu- 
fundibula. Their walls consist of a thin layer 
of connective tissue lined with tesselated, non- 
ciliated epithelium, like that of the air-cells. 
The larger passages contain delicate bundles or 
detached fibres of muscular tissue in their walls.

"Xm., anse'mia of. ('Ai/ai/uirc, want of 
blood. F. aneiiiie du poumon ; G. Lungen- 
andmie.) General or partial bloodlessncss of 
the lung. The former occurs, as in the tissues, 
generally after hx>morrhage and in anaemia ; it 
also is caused by vesicular emphysema and by 
senile atrophy ; the hitter form i.s produced by 
the blocking, or obstruction, of an artery from 
■without or frum within, as from the pressure of 
a tumour or the existence of an embolus. 

Ii., a'pex of. (L. apex, the summit. F. 
sommet du poumon; G. Luiigenspitze.) The 
blunt, uppermost part of the lung; it extends 
into the root of the neck above the level of the 
first rib.

Lujtgenschliig.) See Pulmonary apoplexy. 

Xi., ar'terles of. (F. arteres du poumon ; 
G. Lungenschlagadern.) The arteries supplying 
the lungs are the pulmonary and the bronchial 
arteries. 

The pulmonary artery enters the lung with 
the bronchi and divides frequently, the smaller 
branches not anastomosing with each other, 
until it ends in small afferent arterioles which 
supply the capillaries of two or three adjacent 
air-cells. 

The bronchial arteries accompany the bronchial 
tubes, but do not anastomose with the branches 
of the pulmonary artery ; they are the nutrient 
arteries of the lungs supplying the interlobular 
septa, the bronchi and bronchial tubes, the pul- 
monary pleura, and the bronchial glands ; their 
blood passes chiefly to the bronchial veins, but 
partly to the pulmonary veins, especially that 
from the capillaries of the smallest bronchial 
tubes.

Calculus, pulmonary, and C, bronchial. 

Ii., can'cer of. (F. carcinome du pou- 
mon ; G. Zungenkrebs.) Primary cancer of the 
lung is rare ; in much the larger number of cases 
it is a secondary formation following cancer of 
the mammary gland, the bronchial glands or 
other structures; the primary gmwths are 
usually solitary and large, the secondary ones 
numerous and comparatively small. Scirrhous 
cancer is the commonest form, colloid has been 
met with, but epithelioma is exceedingly rare. 
Secondary cancers are first developed in the 
lymphatic glands, but occasional instances have 



occurred of infecting embolism of the branches 
of the pulmonary artery from direct connection 
of a vein with an ulcerating cancer.

Xi., devel'opment of. The lungs arise, 
behind the tiflh visceral cleft, from a constriction 
of the ventral wall of the primitive cesophagus, 
from which it graduallj' becomes separated as a 
diverticulum, consisting in its outer part of 
niesoblast and lined by hypoblast continuous 
with that of the alimentary canal. The hinder 
end of the bud speedily enlarges and soon 
divides into two lobes or sacs which grow and 
ramify like branched tubular glands. They 
branch again and again to form the bronchial 
tubes and the alveolar passages and air-cells. 

According to some observers the diverticulum 
is double from the tii-st.

branch of the pulmonary artery. It may produce 
sudden death bj' depriving the right ventricle of 
its proper blood-supply, and so arresting the 
action of (he medulla oblongata ; or it may cause 
ansemia of some part of the lung; or it may 
result in hannorrhagic infarction. 

Jt.f em'bollsm of, fat. ('Eju/3o\icrjua.) 
An engorgement of some of the pulmonary 
capillaries and the branches of the pulmonary

ing from a wound of the thorax has been suc- 
cessfully accomplished. 

Ii.s, excre'tion of \ira'ter by. The 
amount of watery vapour given otf by the lungs 
in twenty-four hours has been estimated by 
Valentin to amount to 288 grammes with shal-

ounces, and have a specific gravity of I'OoCi. At 
birth they expand on resjjiration and assume 
the adult characters. 

Ii., for'elg-n bod'les In. Bullets or parts 
of bullets, or pieces of clothing, may be carried 
into the lung by a gunshot wound, and may be-

Ii.s, func'tion of. See Respiration. 

Ii., ^aLngrene of. {Tuyyp(uvu,a.n eating 
sore which ends in mortification. V. gangrene 
du po union ; G. Lungenhrand, Lungengangrun.') 
Death of some considerable part of the lung 
tissue, first distinctly recognised by Laennec. In 
the greater number of cases it is the result of a 
septic inflammation, but it may occur in the 
course of ordinary pneumonia in old persons 
and in those debilitated by previous disease or 
by alcoholic excess ; or when there is consider- 
able hajmorrhagic infarctus, or from a violent 
contusion. The septic inflammation may be set 
up directly, as when a foreign body in a bronchial 
tube putrefies, or the secretions in a dilated 
bronchial tube decompose, or the product of a foul 
suppuration enters the air-passages ; or it may be 
set up indirectly, as by transfer of the infective 
matter through the pulmonary artery from an 
ulcerating cardiac valve or an unhealthy ulcera- 
tion, especially of bone. The olden division into 
the circumscribed and the diff'use forms is not 
supported by some recent writers. The necrosed 
lung is dirty greenish-brown or blackish in 
colour, often filthily stinking, very soft and 
pulpy, and generally surrounded by an inflam- 
matory zone of hepatised lung. There is great 
and severe constitutional disturbance with a very 
weak and quick pulse, and abundant foetid ex- 
pectoration; the sputum generally speedily sepa- 
rates into three layers ; the upper one frothy, 
the middle one liquid, and the lower one con- 
taining sedimentary masses. The physical signs 
are at first dulness on percussion and a crepitant 
rale followed by amphoric breathing and metallic 
rales. 

Ii. gymnas'tlcs. (TviivamiKi), from 
yvfxvaX^w, to train naked ; to exercise.) The 
exercise of the respiratory powers in a regular 
and orderly manner for the prevention or cure of 
disease. It may be accomplished by the practice 
of mountain climbing, rowing, and similar occu- 
pations, by directing a certain number of respi- 
rations to be taken per minute, and by permitting 
patients to carry a stick laid across the back and 
under the arms, its extremities being grasped by 
the hands.

and giving a fine crackling sound to the ear. It 
may occur under the cicatrix of a wound of the 
thoracic parietes, or after fractured ribs, or from 
rupture of the intercostal structures during 
violent straining. 

Ii., bydat'ids of. ('Toa-ris, a watery 
vesicle.) The cj'stic larval condition of the 
Tania eihinococcus ; usually found at the base 
of the right lung, having probably migrated 
from tlie liver. They may attain a large size 
and produce during their growth attacks of haj- 
muptyjis, cough, and expecturation ; they may 
die and may contract with or without expulsion 
of their contents ; or they may produce suppura- 
tion ; the)' ma)' cause death by sutlocation from 
sudden evacuation into the bronchial tubes, or 
they may cause empyema from rupture into the 
pleural cavity. There will be noted dulness on 
percussion over the site, absence of respiratory 
sound and of vocal fremitus, bulging of the 
intercostal spaces may be present, and possibly 
fluctuation and the hydatid fremitus. 

The cy.-tic larva of I'ciitastoma have been 
found in the lung. 

Ii., Iiyperse'inla of. ("T-n-ip, above; 
aifia, blood.) An abnormal quantity of blood 
in, or a congestion of, the lung. 

Jt., hyperae'mia of, active. ('Y-Trtyo; 
nl/ia.) Active congestion of the lungs occuis at 
the commencing stage of pneumonia, and is tem- 
porary in character, passing to the state of in- 
riammation or righting itself very rapidly. It 
nuiy be produced by the sauie intiuenees as pneu- 
monia, or may be caused by a drunken tit, or by 
severe or sudden muscular exertion, or by violent 
cough; it may also result from sudden -stoppage 
of the menstrual tiow. It seldom gives rise to 
a^dema, but there may be suiall crepitation, 
dys])ncBa, and some dulness on percussion, with 
rusty expectoration. 

Ii., byperae'iuia of, collateral. 
i^Xirip ; «I/u« ; L. collatero, to admit on both 
sides.) The form of active pulmonary conges- 
tion which is produced, for instance, when a 
large quantity of ice-cold water is drunk by a 
person when heated. The immediate result is 
thought to be contraction of the arteries of the 
neighbouring organs, liver, spleen, and others, 
which raises the blood -pressure and produces 
the collateral pulmonary hyperemia. 

Ii., byperae'iuia of, bypostat'ic. 
('Yirtp ; al/ua ; viroaTaaLi, a standing under.) 
Same as L., hyperemia of,2}assive. 

Ii., byperse'niia of, mecban'ical. 
('Ttt/p; alpa.) Congestion of the lung pro- 
duced by some mechanical obstruction to the 
return of the blood to the heart, which is 
most frequently mitral stenosis or regurgitation, 
but may be an imperfect action of a dilated 
left venti-icle the result of aortic disease. The 
whole of both lungs is affected, the pulmonary 
capillaries become longer and tortuous, the con- 
nective tissue develops, the small bronchial tubes 
become afl'ected, the muscular tissue of the in- 
fundibula is hypertrophied, and pulmonary 
apoplexy or brown indunttion ensues. There is 
{Treat oppression about the epigastrium, much 
(Ivspnoca, especially on exertion, tniublesoiuc^ 
cough with often bloody expectoration, a small 
quick ])ulse, and more or less lividity of lips. 
Fine crepitant rales are to be lieard, and large 
moist rules when intercurrent bronchitis, which 
is common, occurs. 

Ii., byperse'mia of, passive. {^Yirif), 



alfxd ; L. passh'KS, suffering.) A congestion of 
the pulmonary capillaries from defect of circu- 
latory power, as in exhausting fevers and other 
diseases, in old age, and in the last days of life, 
especially if conjoined with a disordered condi- 
tion of blood, as in uraemia and jaundice ; it is 
generally accompanied by oedema. It occurs in 
the most dependent part of the lung, which 
is of a dark- blue colour from engorgement and 
staining with blood, and is somewhat softened. 
It produces quick and shallow breathing, lividity 
of the surface and depression. There is dullness 
on percussion and a moist crepitant rale on 
auscultation. If the congestion continue it may 
result in Fneumotiia, hypostatic. 

Ii., byper' trophy of. ('Y-ttep, above ; 
Tpocp^, nourishment.) Enlargement of a lung 
from the growth of its tissue to compensate for 
the congenital absence or the morbid abolition of 
a part of its fellow lung. Its structure is gene- 
rally firmer than ordinaiy, and its blood supply 
is greater. 

Ii., bypos'tasis of. Same as F/ieuinonia, 
hypostatic. 

Ii., induration of, bro\<rn. (Late L. 
induro, to harden.) A condition in which the 
lung tissue becomes dark-yellow or brown, firm, 
heavy, granular, and inelastic from continued 
mechanical hypera;mia caused by mitral- valve 
disease ; the walls of the air-cells are thickened 
and much pigment of the nature of hrematoidin 
is present in the connective-tissue corpuscles, the 
capiUaries become tortuous and dilated, and the 
epithelial cells become swollen, numerous and 
pigmented.

hand.) '1 ho l.ujamfntum pulmonis. 

Ii.s, lobes of. (G. Lu)iyi'»Jliigcl, Lungen- 
lappot.) The subdivisions of the lungs in 
Mammals separated by tlie fissures. In man 
there are three lobes in the right and two in the 
left lung. Their number and arrang ment depend 
upon the mode of division of the bronelii. These 
divisions have been named eparterial and hypar- 
terial, according as the)- lie above or below the 
pulmonary artery. The hyparterial bronchial 
-system is universally present on both sides. Tlie 
eparterial system is represented on both sides in 
some animals, as the horse, elephant, and seal. 
It has a representative on the right side only in 
man, monkevs, rodents, bats, and many other 
animals. There is no eparterial bronchus in 
some whales and the porcui)ine. 

Ii., lobular pas'sagres of. Todd's term 
for the i., alveolar passages of. 

It., lob'ules of. (Dim. from Gr. XofSo^, 
the lower part of the ear. F. lobules pulmo- 
naires ; G. Lungenliippchen, Lungenbiiitter.) 
Tlie primary unit of the lungs. It is a more or 
less conical structure composed of air-cells, in- 
fundibula, and alveolar passages converging to a 
bronchiole which forms its apex. The lobules 
are held together and separated by connective 
tissue and blood-vessels. The margins of the 
lobules are mapped out on the surface of the 
lungs by dark lines of pigment. They vary 
much in size. 

According to Kainey the lobules consist of 
four to nine subdivisions of a bronchial tube with 
their terminal intercellular passages and the air- 
cells.

Zi.s, lymphatics of. (F. lymphattques 
des poumons ; G. Lymphgefdsse der Lnnyen.) 
The lymphatics of the lung arise in the lacunar 
spaces, canaliculi, and lymphoid tissue of the 
walls of the air-cells, of the subpleural tissue, and 
of the bronchial tubes ; the small vessels join to 
form three sets of lymphatics, perivascular, peri- 
bronchial, and subpleural, all opening into the 
bronchial glands. According to Sappey they 
arise from a tine plexus. 

Ii., lympbatics of, peribroncb'ial. 
{Wtpi, around, /3(io'yx'"i the bronchial tubes.) 
The lymphatics, originating in the lacunae and 
canaliculi of the connective tissue of the mucous 
lining of the bronchial tubes and forming there 
a fine plexus, branches from which, after a short 
course, perforate the muscular and fibro-carti- 
laginous tissues, form another plexus, and finally 
open into the bronchial glands. The peri- 
bronchial lymphatics are much larger and more 
developed in the child than in the adult. 

Ii., lympbat'ics of, perivascular. 
{Tltpi; L. vasculion, a small vessel.) The 
lymphatics originating in the larunse and canali- 
culi of the walls of the air-cells, forming a plexus 
round or along the branches of the pulmonary 
vessels, and finally opening into the bronchial 
glands. According to Sappey they arise in a fine 
plexus in the air-cells, and there form two sets; 
one joining the bronchial vessels, the other 
forming the trunks which ramify on the surface 
of the lungs. 

Xi., lympbat'ics of, subpleu'ral. (L. 



.s(^/;, under ; pleura.) The lymjiliatics originat- 
ing in the huuma) and canaliculi of the sul)- 
pleiiral connective tissue and of the walls of the 
superficial air-cells ; they ultimately open into 
the bronchial glands. These vessels are believed 
by Sappey not to belong to the pleural tissue, 
but to the ]iulni()nary parenchyma. 

It., malforma'tions of. (L. mains, bad ; 
forma, sha[)e.) Tlie lungs may be wanting in a 
lobe, or thcv may possess more lobes than 
natural; or the wlmle of a lung may be absent. 

Xi., malposit'ion of. {\j.malus ; posilio,

i/ttJCTi?; L. spuriiis, false.) Same as Anthracosis 
ptdmonum. 

Xi., myco'sis of. See Pneumo-mycosis. 

Xi., nerves of. These are derived in part 
from the vagus, in part from the sympathetic 
nerve, and in part from the anterior and pos- 
terior pulmonary plexuses. They accompany 
the bronchi and their subdivisions lying external 
to the cartilaginous plates, and are distributed to 
the bronchial muscle, the blood-vessels, and the 
mucous glands. They contain both meduUated 
and non-medullated fibres and many small 
ganglia. Their ultimate distribution is not 
accurately known ; most, doubtless, go to the 
musculature of the bronchial tubes. 

Xi., oede'ma of. {Oloyi/j.a, a swelling. F. 
oedhne du poumon ; G. Lungenodem.) An effu- 
sion of serous fluid into the air-eells and the 
pulmonary tissue. It may be a result of con- 
gestion and may occur in the course of any 
general anasarca. It may end in consolida- 
tion of the lung tissue or in collapse. Small, 
bubbling crepitation is heard, but there is very 
slight dulness ; frequent, difficult cough, frothy, 
serous expectoration, shortness of breath, and 
more or less lividity efface are present. The lung 
tissue is pale and heavy, and fluid exudes from it. 

Xi., cede'ma of, brown. Same as L., 
iiiduraliou of, brown. 

Xi., os'teo-sarco'ma of. (Oo-xt'o/;, a 
bone; o-ap/cw/ua, a fleshy excrescence.) Secon- 
dary osteo-sarcoma has heen noticed, originating

vaginatus, and the Fentastoma denticulatum 
have each been noticed once ; and Monas lens 
and a Cercomonas have been found in gangrenous 
sputa. See also Gregarinosis pulmonam.

of Bacterium and Bacillus, Sarcina, the Actino- 
myces, and some Hyphomycetes, as Aspergillus 
and Oidium. 

Ii., perfora'tion of. (L. perforo, to bore 
through.) The penetration of the substance of 
the lung from its outer surface, as by a cutting 
instrument or a gunshot wound or a broken rib,

Ii,, plgrmenta'tion of. (L. pigmentum, 



LUNGWORT. 



paint.) The presence of foroij^n eoioured rrmtter 
in the lung: tissue acquired by tlie exercise of 
the respiratory function after birth. Tlie aiiKiimt 
increases as aj?e advances and in projiortion to 
the exposure to contaminated air, such as tliat 
containing' eoal or otlua- dust. The solid sul)- 
stances, chietly carbon, lloatin;^ in the air are 
taken into the broncliial passages with each in- 
spiration, most of tliem are picked up by the 
mucous corpuscles and expectorated ; but many 
penetrate into the air-cells whence they are made 
to pass through the stoinata into the connective- 
tissue cells, where they remain, and into the 
leucocytes in the lymph- spaces of the walls of 
the air-cells, and by them are carried to the 
bronchial glands, where they are deposited. The 
pigment granules lie free in the tissues or are 
enclosed in rounded or fusiform or stellate cells. 
See Anthracosis ptdnionum and Pneumo-eoniosis. 
By some it is believed that much of the pig- 
ment is derived from the blood.

rumpo, to break.) A tearing of the substance 
of the lung usually accompanied by laceration of

term for Anthma. 

Ii., splenisa'tion of. (^irXriv, the spleen.) 
A condition in which the lung is so dense that it 
sinks in water, and cuts with a smooth and fleshy 
surface. It is seen in cases of cardiac valvular 
lesions when there has been so much passive 
hyperemia of the lung with oedema that the

ii., syph'ills of. (G. Zungenhistseuche.) 
Syphilitic disease of the lung is uncommon, but 
it a])pcars certain tliat not only may gummatu 
appear as a result of congenital syphilis, but 
that acquired syphilis may result in structural 
changes resembling tho.se of chronic interstitial 
pneumonia chietly occurring in the lower parts 
of tlie lung, commencing in a gumma, or in peri- 
bronchitis with ulceration of the air-passages, 



or in a thickened patch of the pleura, and 
presenting the usual symptoms of phthisis with 
an Tinusiial amount of ha"nioj)t} sis. It not 
infreijuently results in gangrene and produces 
much scarring and contraction of lung tissue. 

In the congenital form similar conditions may 
arise, and also a pale, tough form of hepatisation 
with obliteration of the caiiillaries and rilling up 
of the air-cells from disintegrated substance and

Ii. to'nus. (T0K09, that by which a thing 
is stretched.) The resistance offered by the 
lungs to distension of their air-vesicles. It is 
j)artly due to elasticity and partly to the un- 
striated muscular fibres which pervade the lungs 
and are under the influence of the vagus. 

Ii.s, traction of, elas'tie. (L. tractus, 
part, of traho, to draw. G. clastischer Zug der 
Lungen.) The influence of the L. tonus in con- 
tracting the lungs and so exerting an auxiliary

ii., u'tricles of. (L. utriculus, a small 
skin-bag.) The L., air-cells of. 

X.s, veins of. The veins of the lungs are 
the pulmonary and bronchial veins. 

The pulmonary vein collects the blood from 
the capillaries of the air-cells, commencing by 
efferent twigs arising generally from the opposite 
side to the aff'erent arterioles ; they form twigs 
which anastomose with each other, and unite to 
form the branches of the Fulmonarg rein. 

The bronchial veins collect the blood from the 
greater part of the capillaries supplied by the 
bronchial arteries, the remainder goes to branches 
of the pulmonary vein ; the twigs unite to form 
the branches of the Bronchial veins.

Jt. erythemato'des. ('E(ir/6)//t«, a red- 
ness upon the skin ; tioov, form.) A synonym of 
L. erythematosus. 

Also, formerly used by English writers to 
denote the milder forms of i. vulgaris in which 
there is no ulceration. 

Ii. erythemato'sus. {'Epvdnfxa. F. 
erytheme centrifuge, Biett, lupus erythemateux, 
scrofulide eryihemateuse. Hardy.) A name 
given by Cazenave to a disease of the skin, first 
described by Biett as Erythema centrifugum, 
which begins as a sharply-defined red patch, 
varying in size from a j)in's head to a lentil, 
witli small, raised, redder spots at the orifices of 
the sebaceous follicles. Tlie reddened margin 
advances gradually, whilst the centre becomes 
scarred over, thus forming a red- bordered disc. 
The disease advances slowly, either by the en- 
largement and coalescence of adjacent patches, 
or by the continual develoi)ment of new putches ; 
miire rarely it commences by the eruption of 
numerous discrete sjjots. It consists of an in- 
fiammation of the j)apillary layer of the cutis, 
esiiecially in the neighbourhood of the sebaceous 
and sudoriparous glands, which become fccon- 
darily involved; tlie blood-vessels are dilated, 
the tissues are infiltrated with leucocytes, whicli 
proliferate and become convertc<l into connective- 
tissue corpuscles and fibres which, as they grow,

cansp the pnpillnc and flic sohnopnus glnnds to 
atrophy. It is chit-tly observed in adults, and is 
somewhat more freouent in women than in men. 
It often begins on tlie sides of the nose, but may 
affect other cutaneous surfaces. It progresses 
very slowly, produces much distiguivment with 
a thin Hat scar, but does not in general affect 
the constitution. No bacillus has yet been found 
in it. It is the Seborrhwa congcstiva of Ilebra. 

"Xm. erythematosus a^grregra'tus, Ka-

Ii. erythemato'sus discoi'des. (AtV- 
fcos, a sort of quoit; tl^os, form.) Kaposi's 
term for the form or stage of L. erythematosus 
in which the isolated spots form a red-margined 
disc, sharply defined at the circumference, but 
fading towards the middle, and having a central 
scale, which is prolonged on its under surface 
into the distended duct of a sebaceous gland. 
The discs grow and in time coalesce. 

Ii. erythemato'sus dlssemina'tus. 
(L. dissei»ino, to scatter seed.) Hebra's term 
for the stage or form of L. erythematosus in 
which extension of the disease occurs by the 
development of new spots in the interspaces of the 
old ones, but which have no tendency to coalesce 
with them. It sometimes presents itself as an 
acute febrile eruption, with swelling of the face 
resembling erysipelas, nocturnal osteocopic pains, 
headache, and effusion into the joints. Flat 
vesicles which speedily burst and leave behind a 
central depression have been seen. The patient 
passes sometimes into a typhoid condition, and 
many such cases are fatal.' 

Ii. erythemato'sus seba'ceus. (L. 
sebum, suet.) That state of L. erythematosus 
in which, before atrophy has commenced, the 
affected part is dry and lustreless, covered with

the sebaceous glands. 

Ii. erythemato'sus teleang-electo'- 
des. {Teleangeicctasis ; Gr. tI5os, form ) The 
form in which there is little surface-change be- 
yond redness from dilated blood-vessels, but 
there is deep-seated thickening, and more or less 
scar results. 

Ii. essentia'Iis. (L. essentia, the being 
of a thing.) The same as L. idiopathicus. 

Ii. ex'edens. (L. part, excdo, to eat up. 
F. lupus rongeant.) A freely ulcerating form of 
Z. vulgaris. The ulceration appears to be due 
to a fatty degeneration of the cells, whose growth 
gives rise to the disease. The tubercles become 
pale and soft with surrounding inflammation of 
the skin, a scab forms which, on separating, 
leaves a smooth red ulcer with somewhat raised 
edges, which spreads laterally and deeply, but 
in the end cicatrises with great deformity. 

In former times cases of tilcerative tertiary 
syphilis have often received this name. 

Ii. exfoliati'vus. (L. exfolio, to strip of 
leaves. F. lupus exfoliatif.) The second chronic 
stage or form of L. vulgaris, in which the 
nodules are very numerous and closely packed, 



forming circular patches two to three centimetres 
in diameter, brownish in culnur, with the central 
part undergoing regressive metamorphosis, re- 
presented by fatty degeneration, caseation, and 
cicatrisation, whilst the periphery consists of 
recently developed nodules. The surface of the 
patch is scaly, rough and fissured. It is Kaposi's 
term for the non-ulcerative form of L. vul- 
garis.

vulgaris, especially of the pudendum, which is 
accompanied by free bleeding. 

Ii. hypertroph'icus. ('TTrtp, above; 
Tpo<pi), nourishment. F. lupus hypertrophique.) 
Cazenave's term for that form of Z. vulgaris in 
which the ulceration is accompanied by large 
granulations and thickening and elevation of the 
margin; it is especially frequent on the cheeks.

dendum. 

The term has also been applied to the condition 
of Z. vulgaris in which the scar is very thick.

tin's term for Z. pustularis. 

J,, lymphat'lcus. {Lymph.) Hutchin- 
son's term for a variety of lupus in which the 
lympliatic spaces are chiefly involved, resulting 
in the production of small, persistent, vesicular 
outgrowths, which contain a lymph-like fluid. 
It originates in childhood, and advances by its 
borders through an infective process which 
travels probably along the lymphatic walls; it 
becomes surrounded by satellite growths, but 
there is no occurrence of the disease in any 
remote part. Ly some it is considered to be a 
form of Lymphangioma or Lymphangeiectodes. 

Ii. maculo'sus. (L. maculosus, speckled. 
F. Itipus maculeux.) The first stage of L. 
vulgaris in which the primary efflorescence of 
lupus nodules is visible as small spots through 
the epidermis. The spots are jellowish brown, 
the surface over them smooth or slightly scaly, 
their consistence soft. They are neither painful 
nor tender.

(jaris which chietiy attacks the face and nose. 
It has no tendency to ulcerate, hence its name. 
The tubercles begin to shrivel and get paler, 
and this condition extends over the whole skin 
art'ected, which is either left red and scaly, or 
white, smooth, and contracted, with an irregular 
spreading bluish or reddish edge. 

Ii., non-ul'cerative. Same as L. non- 
exedens. 

Ii. of Caz'enave. The L. erythematosus.

Ii. of puden'dum. (L. piidenda, the 
privy parts.) A chronic affection of the vulva 
occurring in feeble women between twentj'-five 
and thirty years of age. The disease is charac- 
terised b}' the painless formation of ulcers, which 
gradually progress, the tissue healing and cica- 
trising behind them, and producing great con- 
traction and distortion of the parts. It is not 
characterised by the development of tubercles, 
the lupus deposit being dift'used and accompanied 
by an excessive formation of fibrous tissue. It 
is a form of L. vtilffaris ; but many cases may 
be accounted i., syphilitic.

ment. 

Ii. pustula'ris. (L. pustula, a pimple.) 



A form of L. vulgaris which commences as a 
somewhat raised reddish or livid patch on which 
discrete or confluent tubercles apjtear, having 
suppurating heads like impetigo; the pustules

trophic form of Z. vulgaris in which the scar is 
hard and thick. 

The Z. sclcroticus (F. lupus sclereux^ of Vidal 
presents papillae or warts on its surface, and is 
either primitive or cons 'cutive on Z. vulgaris. 
It is characterised by maculae or rugged, irre- 
gular, horny or bristly prominences, separated 
by furrows with a depressed cicatrix, in which 
the fibrous tissue is considerable, and arranged 
in concentric lamelhE separated by round cells ; 
giant cells are present, and the blood-vessels are 
thickened and hardened. 

X. seba'ceus. (L. sebum, tallow.) A 
synonym of Z. erythematosus, in reference to

erythematosus in which there is marked implica- 
tion of the sebaceous glands, as described under 
Z. sebaccm. 

X. serpigrino'sus. (L. serpo, to creep.) 
The later stage oiZ. vulgaris in which the corium, 
having become exposed by ulceration, is replaced 
by cicatricial tissue, which is gradually covered 
with epithelium, whilst the disease creeps on by 
the development of nodules at the margin of 
the patch or by the coalescence of disseminate 
patches, and forms a gyrate border. It is the 
most common form of lupus of the trunk and 
extremities. Hutchinson is of opinion that this 
epithet is unnecessary, inasmuch as it is the 
characteristic of all lupus to be serpiginous. 

X. sim'plex. (L. simplex, simple.) The 
same as Z. vulgaris. 

X., sing^'le-patcb. Hutchinson's term 
for the form of Z. vulgaris in which, throughout 
the course of tlte disease, there is only one patch.

It. ulcero'sus. (L. ulcerosus, full of 
sores.) The ulcerating form of Z. vulgaris, 

Ii. varico'sus. (L. varix, a dilated vein.) 
A synonym oi Neerus. 

Ii. verruco'sus. (L. verruca, a wart.) 
A distinct variety of lupus, according to ^IcCall 
Anderson. It commences as small, circum- 
scribed, dusky red or violet patches or tubercles, 
either discrete or confluent, becoming elevated 
and warty in parts, progressing slowly, and in- 
fecting neighbouring tissues, and cicatrising in 
the older areas. 

Also, the same as Z. papillaris, but with larger 
papules. 

Ii. vo'raz. (L. vorax, swallowing greedily.) 
A form of Z. exedcns in which the ulceration 
penetrates deeply and produces great deformity.

of a mildly phagedsenic type. 

Ii. vulga'ris. {L. vulgaris, common. F. 
lupus vulgaire, dartre rongeante, esthiomene, 
scrofulide tuberculeuse ; G. fressende Flcchte.) 
A chronic, non-contagious, infective disease of the 
skin in which small patches, the size of a millet 
seed or less, of soft, easily- friable granulation- 
tissue first appear in the subpapillary or deeper 
layer of the corium, and spread by the constant 
renewal of such patches by satellites at the 
margin of the old ones. The patches, which 
are brownish-yellow and translucent, like apple- 
jelly, as described by Hutchinson, at first 
< onsist of small nucleated exudation cells, with 
little stroma, displacing the fibrous bundles 
of the corium ; as they increase in size and 
reach the papillary layer, a delicate connective 
tissue develops between the cells, and then 
spindle-shaped corpuscles are perceived; the 
connective tissue gradually becomes firmer and 



more fibrous; the exudation cells undeigo fatty 
degeneration, the natural tissues, as well as the 
older jiatches, perish by slow absorption without 
ulceration producing glistening scars, or by ne- 
crobiosis leading to ulceration. In addition, the 
fully-developed patch contains small nodules like 
those of tubercle, consisting of a giant-cell with 
e])ithelioid and small round cells, and in small 
numbers bacilli resembling those of tubercle. 
These facts have led to the opinion that the dis- 
ease is essentially a tuberculosis of the skin, an 
0])inion which is not universally accepted. 

Lupus is most common on the face, but it 
attacks occasionally the scalp and other paits of 
the cutaneous surface, as well as the mucous 
membranes, near their outer termination. It 
usually commences a little before puberty, but 
may attack children ; it is very slow in its 
progress, is accompanied with little pain, and 
tends in the end to repair with great disfigure- 
ment from scars, even if there has been no 
ulceration, which is often very extensive and 
destructive.

XiUS« Ancient name for a certain ossicle, or 
very small bone, subjoined to the sacral bone, of 
which it was fabled that it could not be made to 
decay by any power or expedient, neither could 
it be lost, but that it formed the chief germ or 
principle of the re-animated body ; probably the 
extremity of the coccyx is referred to, which is a

Xjymph. (L. lympha, water ; generally, 
but erroueously, connected with Gr. vvfiipa, a 
nymph, employed by the later poets to signify 
water. F. lyinphe ; I. linfa; S. Unfa; G. 
Lymphe.) The watery liquid contained in the 
lymphatic system, consisting of a fluid portion, 
the L. plasma, in which float the L. curpusclcs, 
granular and fatty matter, and, in the ductus 
thoracicus, a few red blood-corpuscles. It is 
thin, slightly viscid, clear, transparent, colour- 
less, or yellowish or greenish, opalescent, of 
a saltish taste, alkaline in reaction, and of a 
sp. gr. of about 1"030, sometimes as high as 
1045. On removal from the vessels it coagu- 
lates in five to twenty minutes, forming a clot 
and serum ; the clot is small, wliitish, soft, and 
only slightly contractile ; sometimes it becomes 
reddish from the presence of red blood corpuscles. 
The analyses of human lymph are not reliable, 
its composition probably varying in different 
parts of its course ; it contains a good deal of car- 
bonic acid, some nitrogen, and very little oxygen. 
Hensen and Hahnhardt found iJ8"63 per cent, 
of water with albumin, fibrin, urea, leucin, salts 
chiefly sodium chloride, and other tnatters. The 
plasma is an exudation from the blood ; and the 
corpuscles are derived in some measure from 
it also, being leucocytes that liave escaped from 
the blood capillaries ; they are also produced in 
considerable quantity by the lymphatic glands, 
by the organs containing adenoid tissue, such as 
the intestinal mucous membrane, the spleen and 
the red marrow of bone; by proliferation of the 
connective-tissue corpuscles; and by tlieir own 
fission. 

The W(n-d lymph is often used alone to signify 
coagulable lymph, or Plastic exudation.

li. -canalicular sys'tem. (L. co>iali- 
culus, a small eliannel. G. l.ympluantilclux- 
system.) Von Ilecklinghausen's term for the 
tnode of origin of the lymphatic vessels, in such 
tissues as the cornea and serous membranes, and 
in the lacuna' and anastomosing caualiculi of the 
branched connective-tissue cells.

Ii., coagrulant. Same as Z., coagulable. 

Xi. corpuscles. (L.corpusculum, a small 
body. F. corpuscules du lymphe ; G. Lymphkor- 
perchen, Lymphzellen.) Colourless, granular, 
protoplasmic, amoeboid, nucleated cells, or leu- 
cocytes, closely resembling the white corpuscles 
of the blood ; they vary in size and the number 
of the nuclei, the smaller ones having a single 
nucleus and little protoplasm, the larger ones 
two or more nuclei and a larger amount of 
protoplasm ; these latter are the more actively 
amoeboid. They are more numerous in the 
lymph which has passed through a lymphatic 
gland than in that which is entering it. They 
are chiefly derived, by fission, from the leucocytes 
of the lymphatic glands, and probably by a 
similar process in the vessels themselves ; they 
are doubtless also formed in the spleen and in 
the thymus, and some may enter the lymphatic 
vessel by diapedesis from neighbouring struc- 
tures. 

Ii., corpus'cular. (L. corpusculum, a 
small body.) Sir James Paget's term for in- 
flammatory lymph which contains many cor- 
puscles, and is characteristic of suppurative 
iufiamniation.

Lytuphspattcn.) Irregular spaces between the 
elements of the difl'ercnt organs and tissues of the 
body, but especially of the fibrous and tendinous 
structures, into which the thinner parts of the 
blood are exuded, and wliich form the com- 
nienceinent of the lymphatic system of vessels. 
The}' are lined by flattened cells. 

Ii. lis'tula. See Lymphatic fislida. 



LYMPH. 



Ii. follicles. (L. folUculus, a small luig. 
G. Lymphfollikeln, BalgfiMikdnA Small, hut 
not very detiuitely cii cumscribod, masses of 
connective tissue, the fibres of which are very 
fine and the meshes of which contain numerous 
lymph cells. They are probably percolated by 
the lymph. The solitary glands of the small 
intestines constitute a good example of lympli 
follicles. 

Also, the outer nodular masses of a lymphatic 
gland. 

Ii. grlands. fF. glandes lymphatiques ; G. 
Lymphdrtiscii.) A generic term for certain

Ii.i grlyc'erln. See Glycerin lymph. 

Ii. bearts. (F. cmurs lymplialiijius ; G. 
Lymphherzen.) Muscular sacs, found in all 
Vertebrata below Mammals, which serve to drive 
the lymph in a definite direction. The walls 
contain plexuses of branched striped muscular 
fibres, and are lined with a layer of flattened 
epithelial cells having wavy edges ; they are 
furnished with nerves and ganglia. 

In Pisces, the caudal sinus, situated at the 
posterior extremity of the spinal column, is con- 
tractile, communicates by a cross branch with 
that of the opposite side, receives lymphatics in 
front, and opens into the caudal vein, the aper- 
ture being guarded by a valve. 

In Amphibia, there are anterior and posterior 
lymph hearts. The anterior lymph heart lies on 
each side of the body behind tlie broad transverse 
process of the third vertebra, amongst the fibres 
of the intertransversarius muscle. It is roundish 
in form and communicates with the vena sub- 
scapularis. The posterior lymph heart lies in 
an intermuscular space on each side of the apex 
of the coccyx. It communicates with a vesicle 
which opens into the common iliac vein. The 
rliythmical contraction of this sac may be seen 
through the skin. In Salamander and Siredon 
there are several pulsating sacs on each side of 
the body and tail. They pulsate visibly after 
removal of the cerebral hemispheres. 

In Keptilia, posterior lymph hearts have alone 
been discovered. They lie in all the Orders upon 
the transverse processes of the hinder vertebi-a3 
or upon the ribs. 

In Aves, lymph hearts have been found in 
Ratitas, Natatoi-es, and Grallae. They have also 
been found in the embryo of the chick, where 
they are of great importance in promoting the 
circiilatiim in the lymphatics of the allautois, 
which open both into tiie jugular and into the 
pelvic veins. They are situated between the 
pelvis and coccyx, and are in communication 
with the lymphatics surrounding the umbilical 
artery. Their pulsations, which are indepen- 
dent of those of the heart, are visible on the 
eighth day, but they gradually become more in- 
distinct and disappear in the adult fowl. 

In Mammalia no pulsating l3mphatic sacs have 
been found. 

Ii., inflam'matory. Same as Z., coa- 
guluhle: 

Ii., move'inent of. (G. Fortbeiccgung 
der Lymphe.) The movement, or circulation, as 



it is improperly called, of the lymph in its 
vessels is largely intlueuced by the contraction 
of their muscular walls and by the pressure of 
the contraction of surrounding muscles in the 
presence of the valves ; in inspiration and during 
diastole of the heart tlie j)rcssure in the large 
veins is decreased, and tlie progress of the lymph 
facilitated. In the lyni])h spaces and rootlets 
any increase in the fulness of neighbouring 
blood-vessels forces tlie lymjih onwards, as also 
does contraction of the muscular fibres of the 
intestinal villi, all muscular contraction and 
movement, and all lessened tension in lyn)i)hatic 
vessels. _ The passage of the lymjih through the 
glands is doubtless very slow, and is proiiably 
effected by the contraction of the muscular fibres 
of their capsule and trabeculie.

purate. 
Xiymphadeno'sis. {Lymph; Gr.aow.) 

The term given by Gowers to a general lymph- 
adenoma in which there is enlargement of the 
lymphatic glands, and, in some degree, of the 
spleen, accompanied by disseminated lym|)hoid 
tumours, with marked and progressive anaemia, 
and some oedema of the face; otherwise called 
Hodgkin's disease, pseudoleucamia, general 
lymphadenoma, malignant lymphoma, lympho- 
sarcoma, antemia lymphatica, adenoid disease, 
and many other terms. 

Its cause is not known ; it occurs most fre- 
quently in children or young persons, chiefly in 
males. The most common antecedent is said to 
be some local irritation, but beyond this all ia 
uncertain. 

The earliest symptom generally is a painless 
smooth enlargement of the cervical, axillary, or 
inguinal lymphatic glands, which is often sym- 
metrical; the glands are painless at first, and 
not adherent to each other or to the skin ; occa- 
sionall}' the deeper glands, bronchial, retro- 
peritoneal, or mesenteric, are the first attacked, 
and then dyspnoea, or pain, or other pressure- 
symptom may be the first, thing complained of; or, 
again, amemia and failure of the general health 
may precede any notable increase in bulk of the 
lymphatic glands. As the disease advances the 
glands grow to a very large size and become 
adherent to each other, sometimes from inflam- 
mation, often from rupture of the capsule and 
confluence of the growth, and the general health 
surters greatly; there is distinct ana-mia, the 
blood becomes thin and pale, the red corpuscles 
being largely reduced in number ; most usually 
the white corpuscles are a little more numerous, 
but in a few cases, the leuca'mic form, they are 
in great excess; the face is markedly pale and 
waxen, haniorrhage from the nose or other partd. 



LYMPH^DUCTUS— LYMPHANGIOPYRETOS. 



and purpuric spots may occur; there is quick 
breatljiug and dyspnoea on any exertion ; tlie 
temnerature is raised and may become persis- 
tently high. At a later stage the breathing may 
be still more affected from pressure of tlie en- 
larged glands upon the trachea or upon the pneu- 
mogastric nerve ; difficulty of swallowing from 
like pressure on the oesophagus may produce 
chronic starvation ; there may be vomiting and 
diarrhoea; ami death may occur from any of 
these things, from exhaustion, from pneumonia 
or oedema of the lungs, or from coma or con- 
vulsion. 

Lj'mphadenosis is a non-inflammatory disease 
of the lymphatic tissue of the body, characterised 
by a growth of the lymphoid and reticular ele- 
ments of which it is composed. The glands may 
be soft 01 hard, harder usually the longer the 
disease has lasted ; on section they are whitish- 
yellow, waxy, and tirm, or whitish-grey, opaque, 
and pulpy; the soft glands yield a milky juice, 
the hard ones none ; in both forms there is a 
great increase of the cellular elements of the 
gland tissue, and in the hard form increase of 
the fibrous tissue also ; they may undergo various 
degenerations, but seldom the caseous. The 
spleen is enlarged, and the tonsils and the follicles 
of the intestinal mucous membrane hypertrophy. 
Lymphoid nodules of various size are often found 
in the spleen, liver, kidneys, lungs, and other 
organs, indeed wherever there is lymphoid tissue ; 
deposits have been observed in the medullary 
and the cancellous tissue of bones. 

Ii., leucae'mic. (Atuho's, white ; aT/u«, 
blood.) The fonu of L^imphadenosis in whicli 
the white blood-corpuscles are very numerous.

Dilatation, simple or varicose, of the lymphatic 
vessels in lesser degree than that which consti- 
tutes lymphangeioma. It may be congenital, or 
may follow an attack of lymphangitis or lymph- 
adenitis, or may result from the presence of 
Filaria sanguinis hominis. The lymphatics may 
become ruptured and discharge lymph. Chyluria 
is by some supposed to be the result of rupture 
of dilated lacteals.

first described by Sydnej' Jones as lymph- 
angioma. It consists of small, colourless, or 
slightly coloured, closely-lying, thick-walled, 
deep-seated vesicles, in irregular groups, filled 
with a colourless alkaline fluid containing a few 
lytnph-corpuscles ; some at least of the vesicles 
are dilatations of the capillary lymphatics. It

ayytlof, a vessel. F. lymphangiome.) A tumour 
consisting chiefly of dilated lymphatic vessels. 
It is perhaps an important condition of some 
other disease rather tlian an independent morbid 
growth ; it occurs in Elephantiasis urabum, in 
Lymph-scrotum, in Macroglossia, and in the 
cutaneous disease called Lymphangeiectodes.

part of their coats, which become swollen and 
infiltrated with small round cells, but the 
iutiina loses its epithelium and appears to be 
uneven and opaque ; white or rosy soft clots, 
composed of a granular mass with numerous 
corpuscles, form in their interior, especially 
near the valves, and suppuration may result. 
The affection is usually secondary to disease 
in the area from which the lymphatic vessel 
is derived, or it may follow the stings of 
insects. It is of frequent occurrence when the 
pelvic connective tissue is indamed after par- 
turition. When superficial, as in the skin, the 
inflamed lymphatic is marked by one or more 
red and tender or painful lines on the skin, 
oedematous swelling in the surrounding and 
more distally situated parts, and enlargement of 
the glands in the neighbourhood. Kigors and 
febrile symptoms are present, which may be of 
great intensity. If the result is favourable the 
symptoms gradually subside or an abscess may 
form, or death with typhoid sj'niptoms may 
follow. Puerperal phlegmasia dolens, elephan- 
tiasis, scleroma, and a malarious form of disease, 
have all been referred to lymphangitis. 
Also called Angeiolcucitis. 

K.malario'sa idlopatb'ica. {Malaria, 
bad air; Gr. i'otos, peculiar; -Triidos, disease.) 
Kio de Janeiro erjsipelas. An erysipehitoid in- 
flammation affecting the lymphatics of anj' part 
of the body, and implicating the surrcjunding 
connective tissue. If limited in extent, conva- 
lescence soon follows; if extensive, death may 
occur from suppuration or from adynamia. 

Ii. nodosa syptailit lea. (L. nodus, a 
knot; syphUin.) A form of tuberculosis, asso- 
ciated with syphilis, occurring in the lymphatics 
of the lung. The centre of the nodule is a small 
miliary tubercle, which becomes surrounded by 
a thick laminated capsule and then caseates and 
breaks down, and in this way a cavity is formed. 

Im., periu'terine. {^f^Ph around ; L. 
uterus, the womb.) Inflammation of the lymph- 
atics of the connective tissue in the neighbour- 
hood of the womb; generally the sequel of L., 
uterine. 

Ii., pulmonary. (L. puhno, the lung.) 
Inflammation of the lymphatic vessels of the 
lung occurs in the course of pneumonia, broncho- 
pneumonia, pulmonary apoplexy, and other 
diseases of the lung ; and is tibrinous or purulent 
according to the nature of the originating disease. 
It also occurs in the course of pulmonary tuber- 
culo.sis, and is a common mode of the spreading 
of the disease, tubercular nodules being formed 
in the course of the lymphatic vessels. 

Ii., retic'ular. (L. reticulum, a little 
net.) The form in which the capillarj' lymph- 
atic plexus is cliiefly aflfected, producing a dif- 
fused redness of the skin, or a network of red 
streaks. It is seen in whitlow, in erythema 
nodosum, and on the hands of persons who have 
been in contart with putrefying matter. 

Ii., septic. (i;j;i|/t9, putrefaction.) In- 



flammation of the lymphatics produced by ino- 
culation of putrid matter. It is not infrequently 
fatal ; it is the form which occurs in dissection 
wounds, and is the precursor oi Septicemia. 

It. tuberculo'sa. (L. tuber, a swelling.) 
A form of tuberculosis, described by Rindfleisch, 
in which a shining, dense, white new growth 
marks out the sublobar divisions of the lung, to 
which is added a chronic desquamative pneu- 
monia. The larger bronchi and blood-vessels 
are imbedded in the branching, slate-coloured 
or black, cheesy masses. 

Ii., tu'bular. (L. tubulus, a small pipe.) 
The form in which the chief lymphatics are 
affected, producing red lines or streaks on the 
skin, which run to an inflamed gland and are 
tender. 

Ii., u'terlne. (L. uterus, the womb.) One 
of the C(jnditions producing puerperal fever, and 
caused by the absorption of putrefying material 
from the uterine cavity after labour, either intro- 
duced from without or generated within ; it may 
also be non-puerperal. Tlie womb is large, and 
painful on pressure or on movement ; the inflam- 
mation may spread to the pelvic cellular tissue 
or to the peritoiueum, and may result in disten- 
sion of the lymphatic spaces of the uterus with 
pus, or in pelvic abscess. 

It., 'nran'deringr. Cumow's tei-m for a 
form of L., reticular, occurring generally on the 
back of the hand, and caused by frequent contact 
with putrefying tissues , it commences in reti- 
cular patches, often connected by wavy lines, 
which are painful ; the glands are enlarged and 
tender.

Ii. g'an'g'llons. {VayyXiov^a. tumour under

Xi. g-lands. (L. glana, an acorn. F. 
ganglions liiixphatiques ; G. Lipiiphdriisen, 
Lymphhiotoi.) Rounded or elongated bodies, 
sometimes solitary, but often arranged in groups 
or chains, as in the groin, in the axilla, in the 
mesenterj', in the posterior mediastinum, and in 
the neck, and placed in the course of the lymph- 
atic vessels ; they vary in size from that of a 
hemp-seed to that of an almond, and generally 
have a depression or fissure at one side, the 
hilum; the vessels carrying lymph to them are 
the afferent lympliatics, those carrying it away 
are the efferent lymphatics. The lymphatic 
glands are composed of adenoid tissue lying in 
compartments, or alveoli, formed by trabecuhe 
derived from the investing capsule which all 
possess, and are usually described as consisting 
of a cortical and a medullary part; but the 
structure is essentially the same in each, and 
the difference consists, firstly, in the form of the 
alveoli or compartments, which are larger and 
spherical or oblong in the cortical part, smaller, 
cylindrical, and irregular in the medullary 
portion ; and, secondly, in the colour, which is 
greyish-white in the cortex, and much darker 
from excess of blood in the medullary portion. 
The capsule is composed of connective tissue, 
containing unstriped muscular fibres ; it sends 
septa or trabecuhe of its own structure into the 
interior of the gland from the surface and at the 
hilum; these form a large number of compart- 
ments or alveoli, communicating with each other, 
which contain the gland tissue, and are large 
and rounded, l-60th to l-24th of an inch in dia- 
meter in the cortical part, smaller and irregular 
in the medullary portion. By means of the cap- 
sule and its prolongations the blood-vessels and 
the nerves enter the gland. The parenchyma, 
composed of adenoid tissue, the proper gland 
tissue, occupies the alveoli, forming rounded 
nodules or lymph follicles in the cortical part, 
and lymphoid cords, or funicular threads, or 
medullary cylinders, containing the blood-vessels, 
in the medullary part, all connected with each 
other throu ghout the gland, but separated from the 
partitions by a narrow space all round, the lymph 
spaces, or lymph paths, or lymph channels, or 
lymphatic sinuses ; these spaces are traversed bj' 
filaments of connective tissue, with some nuclei, 
and contain lymph with a few lymph corpuscles. 
The afferent lymphatics open into the lymph- 
paths on the convex surface of the gland, whilst 
the efferent vessels emerge from the lymphatic si- 
nuses at a slight depression, not always present, 
named the hilum, where they form a dense plexus. 
The lymph traverses the lymphatic sinuses com- 
paratively rapidly, but percolates slowly through 
the medullary substance, and is found to have 
undergone certain changes in its characters as it 
leaves the gland bj' the efferent vessels, becoming 
more disposed to coagulate, and containing many 
lymphoid cells, which are believed to be capable 
of developing into blood-corpuscles. Thei-e are 
about 3.50 lymphatic glands in the human body. 
Those of the occipital region are usually one or 
two in number, those of the neck seven to eight, 
of the axilla three or four, of the cubital region 
two, and of the inguinal region eight or nine. 



They doubtless are largely concerned in the 
formation of the lymph-corpuscles. 

The several lymphatic glands are described 
under Gla)id by their respective names, as G.s, 
lunibar. 

Ii. grlands, false. {¥. faussps glandcs

Ii. plex'us. (L. plexus, a weaving. F. 
reseau lymphutique ; G. Ly mphgefassnelz.) The 
network of lymphatic capillaries in the subcu-

l5'mphatics are, according to one view, believed 
to take origin ; a fine plexus is also found under 
the serous membranes and the synovial mem- 
branes.

hole. F. reseaux lymphatiques des capiUicules 
et des lacunes.') Sappcy's term for a very tine- 
meshed plexus from which, he contends, the 
lymphatics arise. The capilliculi are about -001 
mm. in diameter, but enlarge a little at their 
opening into the lacunas; they consist of a very 
fine membrane without endothelium. The la- 
cunae occur at the confluence of many capilliculi, 
and are irregularly star-shaped, their borders 
being concave ; they vary in diameter from 002 
mm. to '006 mm. This plexus covers the whole 
surface of the external integument, extending 
through the entire thickness of the papilhc, and 
it communicates by means of minute trunks with 
the deeper or subpapillary plexus.

the tnibeculie forming the compartmeuts or 
alveoli of the gland ; and also similar spaces be- 
tween the cortex of the gland and its capsule ; 
they are enclosed by endothelium on the tra- 
becular side, and probably also on the side of the 
gland tissue. They contain a reticulum of fibres, 
to which are attached large transparent endo- 
thelioid plates, and are tilled with l^mph con- 
taining large anicebifonu lymph corpuscles and 
some small lymph corpuscles. 

See also Lymph t^hniscs. 
Is. spaces, perivascular. (Tltpi,

lymphatiques perirasculaircs ; G. perivasculdre 
Lymphrdumen.) The delicate sheaths which 
surround the blood-vessels in the brain, retina, 
and various other organs. The space between 
the sheath and the blood-vessel contains lymph, 
with a few lymph corpuscles. 

Ii. sys'tem. (F. systime lymphatique ; 
G. Lymphycfassnystem.) The several structures 
traversed by the lymph, consisting of the 
l}Tnphatic radicles, the lymph capillaries and 
plexuses, the lymphatic vessels, including the 
lacteals, the lymphatic glands, the receptaculum 
chyli, and the thoracic duct ; some also include 
the serous membranes and cell spaces of the 
connective tissue. The lymphatics only exist as 
a separate system in Vcrtebrata. 

In Pisces, there are numerous independent 
lymph- paths, which originate in a capillary 
plexus beneath the skin and stand in close relation 
to the mucous canals, especially those of the late- 
ral line. The larger lymphatics are distributed 
in the intermuscular ligaments, and especially 
at the base of the tins. They are abundant in 
the intestinal tract of the skate and ray fish. 
In the Teleostei they are chieUy found near the 
spine, and coalesce to form two longitudinal 
trunks, one of which lies on the ventral surface 
of tlie vertebral column, and the other in the 
spinal canal. Fishes have a contractile caudal 
sinus. 

In Amphibia, and especially in the Anura, 
wide Licunar spaces exist beneath the skin, 
separated from each other by delicate connective 
tissue septa. Hence the ease with which the 
skin can be pinched up in these animals. Each 
subcutaneous lymph space communicates with 
the great body lymph sac of the peritoneal 
cavity. Fourteen lymph sacs have been de- 
scribed by Ecker in the frog. The mucous 
membrane of the palate, of the eyelids, and 
membrana nictitans are all rich in lymphatics. 
The lymphatics of the intestines discharge their 
contents into a common lymph sac, which extends 
between the two laniin;e of the mesentery to the 
vertebral column, and opens into the subver- 
tebral lymph space which invests the aorta. The 
movement of the lymph is aided or effected by 
anterior and posterior Lymph hearts. 

In Keptilia, the relations of the lymphatic 
system are essentially similar, the subvcrtehral 
siuus discharging its fluid anteriorly into the 
right and left brachioceplialic veins, and poste- 
riorly into the sciatic and advehent renal veins. 
Only posterior lymj)h hearts have been found. 
The lower Keiitilia possess no lymph hearts. 

In Aves, the subvertebral lymph s]>a<'e becomes 
more defined and is named the ductus tlioracicus, 
but has the same communications. The vessels 
are supplied with valves. Lymph hearts have 
been found in some genera. 

In ilammalia, the ductus thoracicus often com- 



mences with a sinuous dilatation, and receives the 
lymjjhalics of the lower extremities and the pel- 
vis, and the lacteals of the intestine. Running 
forwards it terminates in the left brachiocephalic 
vein. The lymphatics of the head, neck, and 
anterior extremities open into the left brachio- 
cephalic vein. No l3Mnph hearts, or rhythmically 
contractile sacs, have been foiUKl in Mammals. 

Ii. system, development of. The 
several parts of the lymphatic system are derived 
from the mesoblast. 

The lymphatic vessels are developed in con- 
nection with the connective tissue in the same 
manner as the blood-vessels; one of the con- 
nective-tissue corpuscles becomes vacuolated, the 
vacuole increases in size, fills with fluid, and is 
surrounded by a thin cell-wall of protoplasm, 
from which the lymph corpuscles are developed 
by a process of budding ; the original nucleus 
increases by fission, the progeny are embedded 
in the cell-wall, and there become the epithe- 
lium ; neighbouring connective- tissue corpuscles 
that have undergone this change give off 
branches, which meet each other and form the 
lymphatics. In some places the embryonic 
lymphatics form close networks, lymph cells are 
developed in these, and then connective-tissue 
elements and blood-vessels, and thus a lymphatic 
gland is formed.

glands, discharge their contents into tlie great

dexter; occasionally some of tlie branches which 
go to form these truiiks open separately into these 
veins. It has been said by Lippi that some 
lymphatics open into the abdominal veins, but 
tbis assertion is now doubted. Tiie lynipliatics 
of the intestines which convey the chyle are 
called Lacteal vessels. 

The details of the exact origin of the lymph- 
atic vessels are still somewhat uncertain. The 
view commonly taken, which is essentially that 
of von Kecklingliausen, is that they are in inti- 
mate connection with the cell spaces of the con- 
nective tissue and their intercommunicating 
branchlets or canaliculi, and that the endo- 
thelial cells which form the walls of the smallest 
lymphatic vessels or capillaries are directly con- 
tinuous with the connective-tissue cells lying in 
the Cell spaces ; in short, that the cell spaces and 
theii- branches are the rootlets of the lymphatics, 
into which they open by continuity of channel, 
or by stomata between the endothelial cells of 
the lymphatic capillaries. In the other direc- 
tion, these cell spaces are supposed by Arnold to 
be in equally close relationship with the blood 
capillaries, so that plasma exuding from them 
through the stomata in their walls enters the 
cell spaces, from whence the tissues take up 
what they need and give back effete matter, 
which, with the unabsorbed plasma, passes on as 
lymph into the lymphatic capillaries. 

This is supposed to be the common mode of 
origin of the lymphatics, but variations occur in 
ditt'erent structures, as when they arise from 
perivascular spaces, or from the lymph space in 
the tunica adventitia of the blood-vessels of the 
brain, or from the interstitial slits or lacuna; 
between the coils of the tubules of the testicle, 
or the alveoli of other glands; they are also 
believed to arise from all the serous cavities by 
pseudostomata, and in the villi of the small 
intestines in a closed but dilated end. 

According to Sappey, the origin of the lymph- 
atic vessels is essentially difierent; above and 
beyond the plexus above noted he describes a 
plexus of capilliculi and lacunai in the papillie 
of the skin and of some mucous membranes, 
which cannot be filled by a mercurial injection, 
which has no connection with the cell spaces of 
the connective tissue by stomata or otherwise, and 
which has no direct connection with the blood 
capillaries. And, contrary to the general belief 
that there are hardly any, perhaps none, of the 
structures and organs of the body which do not 
possess lymphatics, he is of opinion that they 
are not only absolutely and constantly wanting 
in the whole of the connective tissue, including 
the fibrous tissues with the elastic tissues and the 
osseous tissue, but also in the serous and syno- 
vial membranes, in the central and peripheric 
nervous systems even in the perivascular sheaths, 
and in the blood-vessels, as well as in the 
vesical and ureteral mucous membranes, and in 
some glands as the salivary and lacrymal glands ; 
but that they arise only in the skin, the papillary, 
villous, and some smooth mucous membranes, in 
most true glands and blood glands, in striped 
and perhaps all unstriped muscles, and in cer- 
tain organs, such as the lungs and the uterus. 
The method of investigation adopted by Sappey 
was to subject the vessels to putrefaction and 
the injection of microbes, which give them a 
finely granular aspect and a yellowish colour. 

The lymphatic capillaries, or smallest lymph- 
atic vessels, are irregular in size and shape, and 



contain no valves ; at their origin they join 
each other fre(iuently and form a fine plexus, 
from which the lymphatic vessels arise; these 
uniting constitute the larger lymphatic vessels, 
which have valves and numerous anastomoses. 
As they approach a lympliatic gland they divide 
before entering it, and form the L. vessvlx, uffcient, 
which give their external coat to the capsule of 
the gland and pass throujih it as the Lijinphatic 
sinuacs ; these converge towards the lulus of tiie 
gland, where they form a plexus, from which two 
or three ducts, or often only a single duct, arise, 
the L. vessels, efferent, whicli in turn receive 
from the capsule their outer coats. 

The walls of the capillary lymphatics are en- 
tirely composed of a thin basement membrane 
covered by a delicate layer of elongated wavy- 
bordered epithelial cells, which extends into the 
cell-spaces of tissues containing lymphatirs. 
They possess no valves. According to some they 
possess no walls but are simple tracks in the 
tissues. 

The larger lymphatic vessels have three coats : 
an inner one consisting of a single layer of en- 
dothelial cells, nucleated, oblong, and serrated 
at the edge, the endothelial lining, and some 
layers of longitudinal elastic fibres, the intima ; 
a middle coat of circularly and obliquely disposed 
muscular fibres of the unstriated variet}', with a 
few branched elastic fibres, the media ; and an 
external coat of white connective tissue with a 
few longitudinal elastic fibres and some longitu- 
dinal and oblique bundles of unstriped muscle, 
the adventitia. They possess numerous valves, 
which are formed by a reduplication of the lining 
membrane, and they are more or less moniliform 
in shape. Nutrient blood-vessels are distributed 
to their middle and outer coats, but no nerves 
have as yet been demonstrated. 

The lymphatics are divisible into the super- 
ficial and the deep vessels. The former arise in 
the skin, traverse the subcutaneous tissue, and 
accompany and surround the superficial veins; 
the latter arise in the subaponeurotic parts, and 
accompany the arteries and their venae comites ; 
they are larger than the superficial lymphatics, 
but not so numerous. The lymphatics of each 
plane anastomose freely, but the two planes have 
little or no communication with each other ; the 
anastomosis between vessels on the same plane 
is of a different nature to that between blood- 
vessels, being neither arched nor transverse, but 
consisting in the longitudinal convergence of two 
neighbouring vessels.

Ii. ves'sels, or'igin of, plex'iform. (L. 
plexus, a twining; forma, sliape.) The mode of 
origin which obtains in the skin, some mucous 
membranes and the serous membrane, where 
there are one or more plexuses of vessels which 
vary in size and shape. 

It. ves'sels, perivas'cular. (ncpi, 
around ; L. rascnlum, a small vessel. F. vais- 
seatLV lymphatiques perivasciilaires ; G. peri- 
vasculiire Lymphgefiisse.') The close plexus of 
small lymphatic capillaries which sometimes 
surrounds an artery or a vein or both. Some- 
times the ensheathing lymphatic is single. 

X. ves'sels, praecapil'lary. (L. pr(B, 
in front of; cupillus, a hair. G. vorcnpillare 
Li/mphgefdsse.) The smaller lymphatic vessels 
■which arise from the capillary lymphatic plexus. 
They are short, irregularly-dilated vessels, anas- 
tomosing frequently, and possessing valves. 

Ii. ves'sels, tbrombo'sis of. (Boo'/u- 
/3os, a clot. G. Thrombose der Lymphgcfusse.) 
Coagulation of lymph in a lymphatic, genefally 
as a result of inflammation, especially seen in 
cases of parametritis. 

Tm. ves'sels, valves of. (F. valvules des 
vaisseaux lij)iij)h(itifiH(S ; G. Klappen der Li/mph- 
gcfdsse.) Semilunar folds of the inner coats of 
most of the lymphatic vessels above the size of 
the lymph capilhiries. They were first described 
in 1653 by Kudbeck, and almost simultaneously 
by Bartholin. They are very nunKTous and are 
regularly disposed in pairs on opposite sides of 
the vessel at a distance of 2 to 10 or 13 niille- 
metres from each other ; the free inner border is 
thin, and descriljes a parabolic curve looking to 
the heart ; their fixed convex border is thicker, 
and corresponds at its attachment to the wall to 
a narrowing of the vessel, and the whole valve 
to a bead-like enlargement of the vessel. The 
lymphatics of Pisces and Amphibia contain no 
valves, and they are much fewer in Aves than 
in Mammalia. 

Xiymphat'ics. {Lymph. F. hjmph- 
atiques ; G. Lymphgefdsse.) The Lymphatic 
vessels. 

Ii.s, capillic'uli of. See under Lymph- 
atic plexus of copilliculi and lacuna:. 

Ii.s, cir'cumflex il'iac. (L. circumflexus, 
turned back ; ilia, the tianks.) Lym]>hatics 
which arise in the abdominal walls, converge on 
the iliac crest, accompanj' the cireiinitiex iliac 
vessels, and join the outermost external iliac 
gland. 

Ii.s, dilatation of. Sec Lymphan- 
geiectasis. 

Ii.s, epigastric. ('ETriy«<rT/;to9, over

and join the middle one of the external iliac 
glands. 

Jt.s, inflammation of. See Lymphan- 
gitis. 

Ii.s, intercos'tal. (L. inter, between ; 
costa, a rib. F. tyiii]ihatiques intercostaux.) 
The intercostal lymphatics spring from ttie sub- 
jacent muscles, and are divided into anterior 
and ]iosterior. The anterior accompany the in- 
tercostal veins and pass to the prestemal 
ganglia; the posterior, running beneath the 
tibidus lamina which replaces the intercostal 
muscle, traverse two or three gani;lia, tlien re- 
uniting f )rm a trunk which runs down each side 
of the sjiinal column to the receptaculum chyli. 
Ii.s, ischiat'ic. (To-x'oi^, the hip.) 
Lymphatics accompanying the ischiatic arteries 
which, after passing through eight or ten small 
glands in their course, join the internal iliac 
glands. 

Ii.s, lacu'nse of. See under Lymphatic 
plexus of CfipilUciili and larurxc. 

Ii.s, mam'mary, inter nal. (L. mamma, 
the female breast ; intcrnus, within.) Vessels 
arising over the supra-umbilical part of the 
rectus abdominis, joining a ganglion between 
the xiphoid cartilage and those of the ribs ad- 
jacent, penetrating the thorax, and accompany- 
ing the internal mammary vessels with the an- 
terior lymphatics of the diaphragm to the ductus 
thoracicus on the left side, and the ductus thora- 
cicus dexter on the right. 

Ii.s, ob'turator. (L. obturo, to atop up.) 
Lymphatics accompanying the obturator vessels 
and joining the internal iliac glands. 

Ii.s of back. {Y. lymphatiques da dos ; 
G. Lymphgefdsse des Utickens.) The lymphatics 
of the lower part of the back run to the ganglia 
situated in the fold of the groin, those of the 
upper part run to the ganglia in the axilla. 

Ii.s of blad'der. Lymphatics which, 
along with the very numerous ones of the pro- 
state and those of the vesiculse seminales, join 
the internal iliac glands near the internal iliac 
artery. Sappey doubts the existence of any 
Ij'niphatics of the bladder. 

Ii.s of breast. (F. vaisseaux lympha- 
tiques dii sein ; G. Lymphgefdsse der Brust.) 
There are two sets of these vessels ; one spring- 
ing from the skin over the mammary gland, ttie 
other from the gland itself. The glandular 
plexus is close, and from it branches arise, which 
run forwards and converge towards the areola, 
where they form a dense subareolar plexus; 
from this several large trunks arise that run to 
the axillary ganglia. The superficial plexus is 
close-meshed near the nipple, but looser near 
the periphery of the breast ; the trunks arising 
from it pass to the axillary glands. 

Ii.s of cra'nlal cavity. (Kpavtov, the 
skull.) Lymphatics which arise in the pia 
mater and the choroid plexuses; these latter 
form a trunk, which accompanies the vcn<B 
Galeni, and all pass out of the skull with the 
blood-vessels to the deep cervical glands. 

X.s of di'apbragm. {Ai<'uf)f,aynn, a 
partition wall.) Two anterior trunks, one left 
ami the other right, open into ganglia on the 
antero-latcral jiart of the base of the peric:irdium, 
from whence the}' accompany the internal mam- 
ni;iry lymphatics ; four posterior vessels pass to 
glands on the upper border of the pancreas. 

Ii.s of ear. (F. lymphatiques dupavillon de 



LYMPHATICS. 



r Oreille ; G. Lymphgefiisne des ausseren Ohres.) 
The external ear is covered on both surf'aoes bj' 
a close network of lymphatics, from wliicli two 
anterior trunks run to a lymphatic gland situated 
in fnmt of the tragus; seven or eight posterior 
trunks to the mastoid ganglia ; and four or live 
inferior trunks to the parotid ganglia. 

Ii.s of eye. (F. hjmphatiqucs du sens 
de la vue ; G. Lympngcfasse des Aiiges.) The 
lymjihatics of the conjunctiva arise from a fine 
plexus at the margin of the cornea, about I mm. 
in breadth, which communicates with a wider 
plexus over the sclerotic. The trunks from this 
join with those from the eyelids at the inner 
and outer angles of the eye. In regard to the 
eye itself no lymphatic vessels can be demon- 
strated by injections made into external lymph- 
atics, and some, as Sappey, deny the existence of 
any intraocular lymphatics; but Schwalbe and 
otliers have shown that interstitial spaces exist 
which can be tilled with injection. Schwalbe 
divides them into the anterior lymphatics, which 
commence in the iris and ciliary processes, are 
in communication with the canal of Petit and 
anterior chamber of the eye, and have their out- 
let by the canal of Schleram, finally discharging 
their contents into the conjunctival plexus; and 
the posterior lymphatics, which commence in 
the perichoroidal space between the choroid and 
Bclerotie, and, passing out with the venaj vorti- 
cosie, discharge themselves into the capsule of 
Tenon. This space is prolonged backwards along 
the optic nerve to the optic foramen, forming the 
supravaginal space, and communicating here with 
the subdural space. Another space, named the 
intervaginal or epivaginal space, can be injected 
by direct puncture, or from the subarachnoid 
space, the Injection passing into the perichoroidal 
space, though it will not pass from the pericho- 
roidal into the subarachnoid space. All these 
spaces are lined with endothelium and contain a 
few lymphoid cells, and are supposed to be parts 
of the lymphatic system. 

X.s of eye'lids. (F. lymphatiques des 
paupurcs ; G. Lymphgefdsse der Augenl'ider.) 
The lymphatics of the lids form two plexuses, one 
in front, the other behind, the tarsus. These pour 
their contents into one or two trunks which are 
situated at the outer and inner angles of the eye, 
the former running over the malar bone to the 
anterior auricular glands, the latter accompany- 
ing the anterior facial vein and running to the 
submaxillary Ij'mphatic glands. 

X.s of face. (F. vaisseaux lymphatiques 
de lafnee.) The lymphatics of the brow, lids, 
and cheeks form a plexus, the trunks arising 
from which run from the outer part of the eve 
to the preauricular and parotidean ganglia ; tiie 
trunks arising from the plexus on the nose, inner 
p;trt of the eyelids, fore part of the cheeks, lips, 
and chin, follow the course of the facial artery, 
and terminate in the median submaxillary 

o-MTicrlin. 

Ii.s of gren'ltal or'^ans, exter'nal. 

The lymphatics of the scrotum are very nu- 
merous, and pass to the highest of the most in- 
ternal of the superficial inguinal glands ; those 
of the integuments of the penis are most nu- 
merous on the prepuce, and also pass to the same 
gland ; those of the glans penis arise from a 
superficial or intrapapillary and a deep or sub- 
papillary plexus, and also join the same gland ; 
those of the urethra converge towards the fre- 
num of the penis, and terminate in the inguinal 



glands. In the female there is a close subcu- 
taneous plexus on the labia majora, the nymphae, 
the vestibule, and the clitoris, and around the 
meatus urinarius ; it gives origin to six or eight 
trunks, which cross the labia majora, and ter- 
minate in the glands of the groin. 

Tm.s of groin. (F. lymphatiques de la 
region fessiere.) The sujierficial lymphatics 
form an external set, arising in the skin of the 
groin and opening into the external inguinal 
glands; and an internal set arising on the inner 
part of the groin and the anal region, and open- 
ing into the internal inguinal glands. 

Ii.s of head. (F. lymphatiques des teau- 
ments du erune ; G. Lymphyefassc des Kopjes.) 
The lymphatics of the head form an extremely 
close plexus at the vertex and median line, less 
close as the parts more remote from this are 
reached. They are divided into the frontal, 
parietal, and occipital ; the frontal run down- 
wards and backwards and converge to the paro- 
tidean glands ; the anterior parietal run to the 
parotidean glands, the posterior parietal to the 
mastoid glands; the occipital are divided by 
Sappey into the parieto-occipital and the sub- 
occipital; the parieto-occipital vessels form one 
large trunk beneath the si)lenius capitis, which 
then runs down the posterior border of the sterno- 
mastoid muscle, and terminates in one of the 
ganglia that surround the internal jugular vein ; 
the suboccipital group converge to a ganglion 
situated on the complexus in front of the tra- 
pezius ; from this often double ganglion a large 
trunk arises, which lies under the splenius and 
runs horizontally forwards to terminate in the 
inferior mastoid ganglia.

Ii.s of limb, lo-w'er. The lymphatics of 
the leg are superficial and deep. The super- 
ficial lymphatics spread over the limb in nearly 
parallel lines and arise in a very rich plexus 
covering the integument of the toes, of the sole, 
of the sides of the dorsum, and of the hinder 
part of the heel, and by very delicate radicles 
from the other parts of the skin of the limb ; 
the digital lymphatics form a plexus on the 
dorsum of the foot, from which trunks extend 
along the front and outer side of the leg, and 
follow the track of the internal saphena vein to 
the superficial inguinal glands; the internal 
plantar branches follow the course of the in- 
ternal saphena vein; the external plantar 
branches divide at the knee, some cross the 
ligamentum patelhe to the inner set, others run 
along the outer part of the thigh and bend over 
to the superficial inguinal glands. The deep 
lymphatics form four groups, accompanying 
severally the external saphena vein, the ante- 
rior tibial, the posterior tibial, and the peroneal 
blood-vessels, which all join the popliteal 
glands, the anterior tibial lymphatics after 
passing through the anterior tibial gland ; from 
the popliteal glands branches run upwards, along 
with lymphatics accompanying the femoral 
vessels, and empty into the deep inguinal 



LYMPHATISM— LYMPHOID, 



glands. The lymphatics of the obturator vessels 
open into a pelvic gland lying near the obturator 
canal, those accompanying the ischiatic vessels 
open into the posterior iliac glands, and tliose 
accompanying the gluteal vessels open into 
several glmids found in their course. 

Ii.s of limb, upper. The lymphatics of 
the arm are superficial and deep. The super- 
ficial lymphatics arise from a plexus lying be- 
neath the integuments of the limb, and especially 
dense at the tij)s of the fingers and the palm cd' 
the hand. Those of the fingers converge to the 
back of the metacarpus and run on the posterior 
surface of the forearm, some accomj)anying the 
radial, others the ulnar veins. Those of the 
palm of the hand run up witli the median vein. 
At the elbow, and a little in front of and above 
the epitroehlea, a single or double ganglion is 
usually found, to which the internal group of 
lyni])batics of the forearm converge ; the efferent 
branches from the ganglion ])enetrate the brachial 
fascia, and join the deep lymphatics. The outer 
superficial lymphatics run up one or more venous 
trunks, usually accompanying the cephalic vein, 
and terminating in the subclavicular or supracla- 
vicular ganglion. The deep lymphatics accom- 
pany the several arteries of the limb and end in 
the axillary ganglia. There are usually two 
satellite trunks to each artery.

descending to terminate for the most part in 
the submaxillary ganglia ; a few subcutaneous 
branches from the median part of the lower lip 
terminate in the supra-hyoidean ganglion.

S^Zacrogrlos'sia. (M«h-pos, great ; 

•yXaJrriTa, the tongue. F. macroglossie ; G. 
ZitngcnvorfaU.') A slowly progressing enlarge- 
ment of the tongue, often congenital, with pro- 
trusion from the cavity of the mouth. Accord- 
ing to some, it is supposed to be primarily caused 
by loss of muscular power ; according to others, 
to be an hypertrophy of the whole organ, espe- 
cially of its muscular tissue, from the first; 
Virchow drew attention to the dilated state of 
the lymphatics in this disease, and this condi- 
tion of lymphangeiectasis, together with hyper- 
trophy of the connective tissue, is now believed 
to be the essential morbid condition ; in advanced 
cases the blood-vessels also become thickened 
and dilated, and there is development of lymphoid 
tissue throughout the whole organ. It is said 
to have followed local troubles, such as abscess, 



ranula, salivation, and injury, as well as general 
diseases, such as infectious fevers, whoo]iing- 
cougli, and epilepsy, but in the two latter there 
may well have been local injury. In the early 
stay;e before protrusion, the speech is thick and 
indistinct ; as the tongue enlarges, the mouth is 
kept o|)en, the saliva dribbles away and becomes 
malodorous from the seerelions of fissures and 
ulcers, and the organ becomes dry, hard, and 
cracked; it impedes the intioduction of food by 
its size, and it flattens out the lower jaw and the 
front teeth by its weight. After attaining a large 
size it may cease to grow. The cause of the 
lymphangeiectasis is not known ; it may be from 
obstruction caused by imperfict development of 
the lymphatics, by thrombosis, or by intiamma- 
tion. However caused, the lymphatics become 
very distended, lose their epithelial lining, and 
allow the lymph to transude.

hydrate in moist air. Heated in air it fuues 
and v(datilises at a red heat, and burns with 
a brilliant white flame, giving off clouds of the 
oxide. It is more brittle than silver at ordi- 
nary temperature, but heated it becomes ductile 
and malleable. A wire, 0-297 nnn. in diameter, 
gives, on burning in air, a dazzling l)luish 
white light, equal in intensity to 74 candles, and 
in oxygen of 120 stearin candles, weighing 10 to 
the kilogramme. The light is rich in actinic 
rays, and it has hence been utilized in photo- 
graphy. It was first isolated, but in an impure 
state, by Sir Humphrey Davy in 1808.

the central portion is quiescent, and is called the 
neutral line or zone. An artificial magnet loses 
its magnetism by mechanical force and by being 
raised to a red heat.

ItXag-^nietism. (M«7i/);9, the magnet. 
F. magnetisme ; G. Magnetismus.) A peculiiir 
property capable of being: imparted to certain 
bodies, especially iron, nickel, and cobalt, caus- 
ing them to attract and repel each other, accord- 
ing to certain laws. It is possessed by a natural 



oxide of iron, called the loadstone, a bar of which 

being suspended points nearly north and south 
and attracts iron. Pieces of steel rubbed with 
natural magnets become magnetised, and when 
freely suspended, either by a thread or on a 
pivot, arrange themselves with their long axes, 
running north and south, one end being north- 
seeking, the other south-seeking. The north- 
seeking pole of one magnet attracts the south- 
seeking pole, and repels the north-seeking pole 
of another. No magnet can be obtained having 
one pole only. The earth is a huge magnet, but 
the magnetic north pole of the earth does not 
coincide with the geographical North J'ole, being 
situated about 17^—20^ W., and the diH'erence is 
called the declination of the needle ; this is re- 
turning to true north at about the rate of 7' per 
annum. When a magnet is balanced on a hori- 
zontal axis, and is free to move, it is horizontal 
at the equator; but if moved towards the North 
Pole the north pole of the m:ignct dips, if to- 
wards the South Pole its south pole dijis. At the 
North or South Pole a magnetic needle stands 
vertically to the surface of the earth. The de- 
clination and dip of the needle and the intensity 
of the magnetic force are undergoing change in 
any given spot of the earth's surfnce. 

K/L., an'imal. (G. thieriscJier Magnetis- 
mus, Lebcnsmagnetismus.) The dynamical dif- 
ference between opposite and remote parts of the 
body, as between the right and left sides, the 
front and the back, and the head and foot, which 
resembles the difl^erent and opposite powers of 
the poles of a magnet. These difl'erences were 
recognised by Reichenbach in his researches on 
the Od force. He considered it to explain the 
likes and dislikes or antipathies and sympathies 
of individuals for each other, ojiposite polarities 
attracting, similar repelling one another. In 
the doctrine of Mesmer, the influence which one 
man exerts upon another may be transmitted by 
objects he has touched, and may be iutensitied 
to an extraordinary extent by manipulation. It 
may thus come to act as a curative agent in dis- 
ease. Braid directed his attention to the in- 
fluence of certain movements, named passes, in 
inducing states, either of total unconsciousness, 
or of submission on the part of the mind and 
body of the subject, to the will of the operator, 
and remarkable phenomena may thus be ex- 
hibited in neurotic persons. See Animal mag- 
netism, Hgpnotism, Mesmerism, and Metallu- 
thcrapg.

which itself is a great mngnet, with its poles not 
quite coincident with the geographical poles. It 
causes the magnetic needle to range itself north 
and south, and produces the declination and the 
inclination of the needle. The magnetic in- 
tonsitv of the earth slowly alters ; the compass 
and the dipping needle both have daily and

occur irresularl}', producing magnetic storms. 

IW., the'ory of, Am'pdre's. (Aiiiptre.) 
A theory of magnetism in opposition to the 
theory of two magnetic fluids, proi)osed by Am- 
pere, by which he assumes that each individual 
molecule of a magnetic substance is traversed by 
a closed electric current, free to move about its 
centre, but compelled to quiescence by a coercive 
force, and exhibiting, when it is given a parallel 
direction, tlie phenomena.

and mares are included ; but especially applied 
to a very grave disorder, essentially differing 
from human syphilis, which has been very fatal 
in France. The first symptoms in the stallion 
are circular, circumscribed swellings of the skin 
of the hind-quarters, differing from farcy buds in 
that they are in the skin itself; they are soon 
followed by constitutional symptoms, variable 
appetite, oedematous swelling of the sheath of 
tbe penis extending to the umbilicus, similar 
swellings of one or other hind legs, with lame- 
ness and stiffness in moving. In the mare there 
are the local signs of the sexual orgasm, fol- 
lowed by oedematous tumefaction of the labia 
majora which become cold and clamni}', the 
swelling spreading to the perin;cum and the teats. 
The mucous membrane of the penis and the 
vagina is injected in patches, but there are no 
pustules or ulcers, and there is a free muco- 
purulent discharge. The pulse is slow and 
feeble, and partial paralyses and epileptic attacks 
occur ; one ear, or a lip, or the tongue, or an 
eyelid may be paralysed ; the conjunctiva se- 
cretes purulent stuff, and the cornea becomes 
ulcerated. The disease may last weeks or months, 
the animal gets weaker and dies, or if recovery 
takes place it is very slow. The disease is only 
communicable by coitus.

bones. A chronic disease of great rarity oc- 
curring in adult life, in which the bones be- 
come soft and pliable owing to the removal of 
their salts; their specific gravity is diminished, 
and they can be easily cut with a knife. The 
periosteum is usually thickened, and when re- 
moved the surface of the bone is porous, a bloody 
or yellowish fluid exuding from the pores. The 
medullary cavity and spaces are enlarged. The 
medulla is highly congested, the blood-vessels 
being widely dilated, and extravasations nu- 
merous. The colour varies from deep purple to 
light yellow, according to the relative proportion 
of oily matter, and in the later stages the me- 
dullary cavity may be filled with a clear, viscid,

mucoid or gelatinous fluid. As a result of the 
softness of the bones, the spine, pelvis, thorax, 
and bimes of the extremities become bent, 
twisted, and deformed, and in some instances 
fracture occurs. The bones of the head are 
rarely affected. The muscles become wasted 
and undergo fatty degeneration. It especially 
affects women who have had one or more chil- 
dren, and is most frequently seen between the 
ages of twenty-five and forty. The symjjtoms 
are pain and tenderness in or over the affected 
bones, a feeling of weakness causing uncertain 
gait, nervous excitability, .=0 that painful spasms 
of muscles occur on gently stroking the skin 
over them. The proportion of salts in the urine 
seems to be sometimes increased. It usually 
terminates in death. Also called Osteomalacia 
and MoUities os.iiu/n.

arteries. 

TtL. bone. (F. os malaire, os de la pommette, 
osjugal, OS zygomatique ; G. Jochbein, JFangen- 
bein.) An irregularly-shaped bone which forms 
the prominence of the cheek on each side of the 
face below and to the outer side of the orbit. It 
presents a body with three surfaces and three 
processes. The body is chiefly composed of com- 
pact tissue, but has sometimes a cavity in its 
interior named the sinus jugalis, which commu- 
nicates with the antrum of Highmore ; it has 
three surfaces, an external surface (F. face 
antero-externe ; G. Gedchlsjlache), to which the 
orbicularis palpebrarum and zygomaticus major 
and minor muscles are attached, and where are 
the openings of one or two malar foramina for 
the malar nerve of orbital ; an orbital surface 
(F. face superieure dti face postero-interne ; G. 
Augenhohlevfldche'), with an opening for the 
malar nerve of orbital, and another for the zygo- 
matic nerve ; and a temporal surface (F. face 
inferiore dn face postero-interne ; G. Schldfen- 
grubeuflache), to which the temporal muscle is 
attached, and with the opening of the foramen 
zygomaticum temporale for the zygomatic nerve. 
The processes are the frontal, the temporal, and 
the maxillary, which articulate severally with 
the corresponding bones ; it also articulates with 
the great wing of the sphenoid bone. The bone 
forms part of the outer wall and floor of the 
orbit, as well as of the temporal and zygomatic 
fossae. It is developed from three points of 
ossification, which appear at about the eiglith 
week of intra-uterine Life and unite about the 
end of the twelfth. 

The malar bone is absent in some Mammalia, 
and in Batrachia, serpents, and most fishes ; in 
birds it is only a thin splint forming part of the 
zygoma ; its orbital plate is present only in man 
and apes ; in porpoises the zygomatic portion is 
a distinct bone. 

M. bone, frac'ture of. A very rare oc- 
currence, the result of sevt-ie and direct violence. 



IVI. canal'. {?. canal malaire.) A T-shaped 
passage whicli commences on the inner surface 
of tlie orbital process of the malar bone by a 
single orifice, and opens by two on the facial 
surface of the bone. It transmits the malar 
branch of the orbital division of the superior 
maxillary nerve and a small arteriole. 

M. nerve, of or'bital. (F. ramean 
malaire du nerf orbitaire ; G. Wangenhautnerv.) 
A branch of the orbital division of the superior 
maxillary nerve. It lies in the fat of the lower

orifice of the malar canal, and emerging by the 
outer orifice, is distributed to the skin over the 
malar bone. 

TfL. nerves, of fa'clal. (F. rameaux 
malaires du nerf facial ; G. Wangenzweige des 
Gesichtsnerv.) Branches of the temporo-facial 
division of the facial nerve. They cross the 
malar bone to reach the outer side of the orbit 
and supply the orbicularis palpebrarum muscle. 
They communicate with the lacrymal and supra- 
orbital nerves and with the malar branches of 
the superior maxillary nerve. 

TIL. point. The point situated at the place 
where a horizontal line, running from the lower 
border of the orbit to the upper border of the 
zygomatic arch, crosses a vertical line running 
from the external border of the fronto-malar 
suture to the tubercle on the external inferior 
angle of the malar bone. 

ac. pro'cess of fron'tal bone. (F. 
apophyse orbitaire du frontal ; G. Jochfortsatz

bone. 

X^ala'ria. (I. mal'aria ; from malo, bad ; 
aria, air. F. miasine ; G. Miasma.) The poison 
which produces intermittent and remittent fevers, 
and which is generated in marshy or swamp}' 
districts, or where there is an insufficiency of 
healthy vegetation and a waterlogged soil. Its 
exact nature is not yet settled, but all modern 
observation points to some microscopic vegetable 
or animal organism as the morbific agent ; see 
M. microbes and M. infusoria. Its most frequent 
mode of reception into the body is by means of 
the atmosphere, but it may be taken in water or 
other fluids exposed to marsh air, as well as by 
means of solid matters, such as fruits so exposed. 
It is incapable, apparently, of reproduction in 
the animal body, it is not propagated by an in- 
fected person, and it produces in the system 
solely its own specific effects, these being not 
only the special fevers, but also disturbances of 
nutrition evidenced by enlarged spleen and a 
peculiar cachexia; it influences also other dis- 
eases, making them in some degree intermittent. 



MALAETA— MALARIAL. 



It may be carried long distances and considerable 
lieiglits by the wind, but is arrested in its progress 
by a belt of forest. It has little or no influence on 
domestic animals. The intensity of its action is 
greatly increased by a persistently high tem- 
perature and by the breaking up of the ground ; 
it is decreased by cold, as in winter, and by the 
growth of healtliy vegetation, especially, accord- 
ing to some, by the presence of the species of 
eucalyptus.

la. microbes. (Mt^jios, small ; (iio^, life. 
A micro-organism believed, but not certainly 
proved, to be the cause of malarial fever.- Klebs 
and Tommasi-Crudeli found bacilli of from 2—7 /j 
in length in earth from a marshy district, which 
grew into convoluted threads, the protoplasm of 
which became segmented and thrust forth 
brushes of short rods from the parts exposed to 
the air, or developed persistent spores in their 
interior. These bacilli injected into rabbits pro- 
duced, according to Klebs, malarial symptoms, 
but the purity of the culture has been called in 
question. More recently Cuboni and Marchia- 
fava have found short moving bacilli, closely 
agreeing with those described by Klebs, provided 
with terminal spores at their two ends at the 
period of access of the fever. Laveran and 
Richard, on the other hand, have found amceba- 
like bodies of the size of a red blood-corpuscle 
in the blood of malaria patients. These bodies 
contain dark red, actively moving, pigment cor- 
puscles in their interior, and can send forth long 
tine processes. Still more recently Alarchiafava 
and Celli have found blue corpuscles of various 
form and size in the i-ed blood-eori)uscles, and v. 
Sehlen observed granules from 0-5 — I'O fx in 
size, staining with methyl blue, partly within 
and partly between the red corpuscles. See also

Tfl. bu'bo. {huvftwv, a swelling in the 
groin.) A swelling of the inguinal or other 
lymphatic glands having periodical accessions of 
pain, and accompanying some form of inter- 
mittent fever. 

IVI. cacbex'ia. (Kox^^tn, a bad habit of 
body. G. Malaria- Siechthnm.) The persistent 
condition of ill health often produced by re- 
peated or prolonged attacks of ague or other 
malarial fever, or by long residence in a mala- 
rious neighbourhood without anj' definite attack 
of fever. The complexion is sallow and muddy, 
the skin is soft, inelastic, and clammy, the tongue 
is furred, the appetite bad, and the bowels torpid ; 
there is considerable anaemia producing giddi- 
ness, noises in the ears, shortness of breath on 
exertion, and palpitation ; there is great depres- 
sion of spirits, lassitude, and often neuralgia. 
The spleen is generally very large, often very 
hard, sometimes soft ; the liver is enlarged and 
hard ; and the kidney is said to be not infre- 
quently the seat of amyloid degeneration ; the 
organs generally are the seat of pigmentary de- 
posit, and the blood contains mucli pigment, con- 
stituting the condition called Mclauccmia. 

M. diseases. These include simple or 
benign intermittent fevers, such as ague, ano- 
malous masked fevers, pernicious inteimittcut 



fevers, remittent and continued fevers, malarial 
cachexia and malarial neuralgia. They are en- 
demic in almost all the warmer parts of the 
world that are swampy, and in those districts 
that arc liable to occasional overflow of rivers or 
of the sea, though they may occur in mountainous 
regions when these conditions are absent. .No 
race or nationality enjo} s immunity from mala- 
rial affections, though negroes are less liable to 
be attacked. Men are more subject than women. 
Children 8uff"er most frequently with intermittent 
bowel troubles. In youth either continued 
fevers or quotidian or tertian intermittents are 
most common. In middle life all forms are met 
with ; whilst in advanced age, though the system 
is less liable to infection, very pernicious forms 
are apt to occur. Those who are weak and 
anasmic are most liable to be attacked. The 
period of incubation is generally reckoned at 
from six to twenty, or in America thirty, days, 
but Hertz states that he has repeatedly perceived 
well-marked symptoms of malarial infection 
within half an hour after exposure to the emana- 
tions of a marshy ditch, whilst other observers 
liave noticed as long a period as six, or even ten, 
months to elapse. 

IWI. epilep'sy. ('ETri\jjv;/ut, the falling 
sickness.) A few cases have been reported in 
which residents in malarious districts have been 
attacked by epilepsy, which is preceded by great 
rise of temperature, followed in the intervals by 
facial neuralgia, and abolished on removal from 
malarial influences.

frequently-recurring, and the intermissions dis- 
tinct. 

TIL. g^an'grrene. (Vayypaiva, an eating 
sore which ends in mortitieation.) A form of

IMIa.l'ta (Sax. mealt ; from melt an, to melt ; 
G. Malz. F. malt d'orge, drtche ; I. malto, orzo 
rivoltato ; S. malta.) Grain, usually barley, 
which has been steeped in water, kept at about 
70° F. ('21-11° C), allowed to germinate, and 
when it has arrived at a certain stage ex- 
posed to heat. In steeping, it takes up about 
40 to 50 per cent, of its weight of water, 
whilst it loses about one per cent, of its 
solid constituents. In germination, it loses by 
oxidation about 10 per cent, of its weight. It 
differs from barley in the larger proportion of 
maltose or sugar it contains resulting from the 
action of the vegetable ferment, diastase or 
maltin, on the starch contained in the seeds ; 100 
parts of dry barley yield 63'4 starch, 16"3 pro- 
teids, 6'6 dextrin, 3-1 fat, 7"1 cellulose, and 2'4 
ashes. When malted, admitting 10 '2 parts of 
loss by solution and germination, the 88*8 parts 
of malt which are produced contain 48-9 starch, 
16 proteids, 6-9 dextrin, 2 sugar, 2"5 fat, 7 '3 
cellulose, and 2'1 ashes. The chief loss is there- 
fore in the starch. 

M[. bath. A bath into which four to six 
pounds of malt, boiled in seven or eight pints of 
water, have been added. 

M., ex'tract of. (L. extraho, to draw 
out of.) This substance is prepared by digest- 
ing malt with water, straining, and evaporating 
the product to the consistency of thick honey. 
It contains diastase, and so acts as a digestive 
ferment, as well as being itself nutritious. It is 
useful in cases of imperfect nutrition and mal- 
assimilatioD, and in phthisis. The dose is four 
drachms. See Extractum malti, U.S. Ph. 

IM. liq'uors. Term applied to the diffe- 
rent kinds of ales and beers containing alcohol,

9Xa.l'ta.. An island in the Mediterranean 
Sea, about seventeen miles long by nine miles 
wide, sixty miles south of Sicily. In winter the 
climate of Malta is temperate and healthy, but 
variable. The temperature from October to May 
ranging from 51° to 71" F. (10-55° C. to 21-66° 
C.) From July to October it ranges between 
80° and 90° (26-66° C. to 32-22° C.) The north- 
east wind, named Gregale, occurs in winter, 
and is exceedingly strong and cold feeling. 
The south-east wind, named Scirocco, occurs 
chiefly in August and September, and is moist and 
depressing. In the summer and autumn there 
is risk of malarial fever, as well as dysentery 
and diarrhoea. The chief residence is Valetta 
and its suburbs. 

Malta has been recommended in phthisis and 
chronic bronchitis, but probably not very wisely. 

AX. fe'ver. A fever of long continuance 
and a variety of symptoms indicating the im- 
plication of many organs and structures ob- 
served in Malta and several other places on the 
Mediterranean, such as Gibraltar, Naples, and 
Catania. It usually commences slowly and in- 
sidiously, with lassitude, weariness, shiverings, 
bad appetite, nausea, thirst, and headache, which 



is often severe ; the tongue is furred, flabby, and 
red at the edges, the pharyngeal mucous mem- 
brane is congested ; the bowels are, as a rule, 
constipated, the motions sometimes streaked 
with blood, and there are occasional attacks of 
diarrhoea ; there is enlargement of the liver 
and spleen, gurgling in the iliac fossa, and 
tympanites ; there is roughish breathing and 
some crepitation at the lung bases, and profuse 
perspiration with sudamina ; delirium is rare. 
The symptoms continue for ten or fourteen days 
and then decline for a time ; soon there is 
a relapse, with shivering, headache, exalted 
temperature, perhaps up to 40° C. (104° F.) or 
more in the evening, sleeplessness, and profuse 
perspiration ; there is seldom delirium ; joint 
complications occur, one of them becomes red, 
swollen, and very painful, then another and an- 
other, then the testicle may be affected, and then, 
it may be, the sciatic or intercostal nerves ; this 
condition may last many weeks, during which 
anaemia makes great progress, and the patient is 
very weak and thin ; not infrequently there is 
another improvement and again a relapse, and it 
may be months before real convalescence occurs, 
but recovery is the rule, the deaths being only 
about two per cent. The exact nature of the 
disease is disputed ; probably it arises from putre- 
factive emanations, possibly modified by malarial 
influences. In fatal cases, Peyer's patches are 
found normal, or with slight proliferation of the 
lymphoid tissue, the mesenteric glands are only 
slightly enlarged, the spleen is large and difflu- 
ent, with congestion of the Malpighian bodies ; 
the kidney is similarly affected ; the liver is con- 
gested, leucocytes are found in the interlobular 
fissures, and the hepatic cells are the subjects of 
cloudy swelling. Micrococci are found in very 
large numbers in the spleen, and in smaller 
numbers in the liver and kidney. 

DXal'tha.. (Ma\6a, a mixture of wax and 
pitch.) A variety of Bitumen ; it is a wliite, 
brittle, waxy substance, of sp. gr. 077, being

BXalthu'sianism. {Maltlms.) The 
teaching ot Malthus in respect to the increase of 
population, which he demonstrated to be under 
ordinary circumstances much greater than the 
increase of the means of subsistence. Hence he 
was led to consider the checks to the increase of 
population, which he arranged under three 
heads, moral restraint, vice, and misery. He 
strongly inculcated the necessity of moral re- 
straint, contending that it was immoral to beget 
children without fair prospect of being able to 
provide for them.

DXal'tin. A nitrogenous ferment existing, 
according to Dubrunfaut, in malt, and much 
more active than diastase.

Blal'tose. C|.iTI,„(),, + HoO. A variety of 
sugar obtained during the process of malting, as 
well as when a starchj- substance is acted on

sugar formed by the action of the animal diastase 
on fenuents. It is allied to saccharose or cane 
sugar more closely than to glucose, and is isomeric 
with lactose. It is crystalline. It is dextro- 
rotatory, and its solution has the power of 
polarising light to a greater degree than solution 
of glucose. It is not so sweet as, and reduces 
copper sulphate less easily than, glucose. It can 
be converted into dextroglucose by boiling with

M. s-weat'ing- sick'ness. A disease re- 
sembling, but difl'erent from, cholera, described 
by Dr. Murray in 1840. It commences with 
rigors, followed by headache, lieat of skin, di- 
lated pupils, buining sensation at the epigas- 
trium, restlessness and thirst, and generally 
copious watery motions, smelling like the flesh of 
carnivorous anim.ils slightly tainted. In many 
cases vomiting occurs of a similar fluid, with 
cramps in the extremities, and the skin t-oon 
becomes bathed in perspiration. There is gre;it 
oppi'cssion in breatliing, with anxiety and weak 
rapid pulse. The mental faculties remain clear 
till near the end, when coma intervenes, and 
death may ensue within ten hours of the com- 
mencement of the attack. Vomiting and cramps 
were neither constant nor prominent symptoms, 
but in severe cases no urine is passed, and the 
evacuations continue; while, when the disease 
takes a more favourable turn, the j)ulse becomes 
fuller, the precordial oppression less, some dark 
green fteculent matter is passed, a little urine 
is secreted, and the patient sleeps. After a 
remission of 24 to 48 hours the same train of 
symptoms is apt to be renewed, and as the 
disease goes on remission succeeds the paroxysm 
with a regular periodicity, and the attacks be- 
come gradually slighter.

the secretion of milk formed by the mammary 
glands. 'J'hey are vivijiarous and warm-lilooded, 
and have hairy integuments, if not in the adult, 
as in Cetacea, yet in tlie ftt'tal condition. The red 
blood-corjiuscles are discoid, or elliptical as in the 
camel, and non-nucleated; the white corpuscles 
are splierical and nucleated. There are two dis- 
tinct lungs. The heart has four distinct cavi- 
ties ; two of which, the right auricle and 
ventricle, drive the blood through the lungs, 
constituting the lesser circulation ; whilst the 



other two, the left auricle and ventricle, drive 

the blood through the body generally, con- 
stituting the greater circulation. The embryo 
has an amnion and allantois. There are seven 
cervical vertebra?, except in the Manatee and 
Cholocpus llojf'mauni, which have six, and 
Brady pus torquatus, which has eight, and 
Bradypus tridaetylus, which has nine. The 
atlas is ring-like, the cavity being crossed l)y a 
transverse ligament. The os odontoideum is 
ankylosed to the second vertebra. The dorsal 
vertebise vary from ten to twenty-four, the 
lumbar from two to nine, the sacral from one 
to ten, and those forming the tail from two to 
forty-six. The brain-case has ossitied walls. 
The occipital has two condyles. The mandible 
articulates with the squamosal by a convex or Hat 
condyle, and consists of two rami. The Wolffian 
bodies remain only as rudiments. Most mammals 
are diphyodontal. The oldest fossil forms belong 
to the Marsupials, and are found in the Trias.

M. duct-cyst. See M. gland, cyst of, 
duct. 

tfl. grland. (F. glande mammaire; G. 
Brustdriise.) The milk-secreting gland; it lies in 
woman upon the pectoralis muscle of each side, 
extending from the third to the sixth rib. It con- 
sists of numerous alveoli embedded in connective 
tissue having branched corpuscles, and in some 
animals bundles of unstriped muscular fibre cells. 
Each alvedus is formed of a membrana propria 
consisting of branched connective-tissue cells, 
and is lined, when the gland is inactive, with a 
single layer of flattened epithelial cells, but during 
lactation the cells become larger, columnar, and 
contain fat-globules. The alveoli open, several 
together, into the lactiferous ducts, which unite 
to form fifteen to twenty larger or galactopho- 
rous ducts, conveying the milk to the nipple. 



The alveoli are coUectid into I'llniles, these into 
larger and larger lobules, and tlie largest lolmles 
into lobes held together by areolar tissue and 
more or less adipose tissue. Tlie gland is suji- 
plied by arterial twigs from the thoracic 
branches of the axillary, from the intercostal, and 
from the inti inal mammary arteries, and by the 
external mammary arteiy. The veins are very 
numerous and large, and many are quite super- 
ficial. The nerves arc divisible into cutaneous 
and glandular ; the cutaneous proceed from the 
hiteral and anterior branches of the second to 
the sixth intercostal nerves, and from tlie ante- 
rior thoracic nerves given olf from the brachial 
plexus ; the glandular nerves are branches of 
the fourth to the sixth lateral cutaneous pectoral 
nerves, and the sympathetic branches which enter 
the gland run in company with the long thoracic 
artery and with the anterior rami perforantes 
of the intercostal arteries. The lymphatics dis- 
charge themselves into those of the axilla and 
anterior mediastinum. In woman the long 
diameter of the gland is on the average 128 mm., 
the vertical diameter 111 mm., the left being 
usually the largest, the thickness is 54 mm. Its 
volume is 223 cub. cent. ; its weight 254 
grammes. Sp. gr. of the gland substance 1-0455, 
The ducts have a diameter of 1-7 to 2-3 mm. 
The external opening of each duct is about 0-6 
mm. wide. The acini have an average diameter 
of Q'\'2 mm., extremes 0'08 and 0*16. In man 
the weight of the gland varies from I to 137 
grammes ; the diameter from 3 to 21 mm., 
average 7"7 mm. ; thickness 3 mm. The papilla, 
or nipple, which is from 2 to 5 mm. high, is 
situated about 12 cmt. from the middle line, and 
is just below the fourth rib in the fourth inter- 
costal space or over the fifth rib. 

Supernumerary glands arc not infrequent, and 
they may be placed either near to the normal 
ones, or in the axilla or the groin, or on the thigh, 
the back, or the shoulder. Sometimes a normally 
placed gland has two or three nipples. 

The mammary glands are by many believed to 
be modified sebaceous glands, the hairs having 
disappeared ; those of Monotremata appear to be 
modified sudoriparous glands. 

The presence of mammary glands is restricted 
to the Mammalia, though an analogous secretion 
is produced in some birds by the crop. In 
Monotremata the mammary gland possesses no 
nipple, and consists of a group of several tubes, 
resembling the other integumentary glands, 
opening in Ornithorhyncus on an area destitute 
of hairs but not elevated, and in Echidna in a 
pouch-like depression. In Marsupials and all 
higher mammals nipples are present, and the 
gland is placed inside a permanent cutaneous 
pouch. The number of glands in the diS'erent 
orders generally correspond to the average num- 
ber of young produced at a birth. As a rule 
they form two rows which, when numerous, as 
in Suidae and Carnivora, extend from the inguinal 
to the pectoral region. In many of the Didelphia 
they are arranged in a circle on the abdomen. 
They maj' be situated only in the lumbar region, 
as in Perissodactyla, Kuminantia, and Cetacea 
or they are limited to the pectoral region, as in the 
elephant, Sirenia, many Prosimii, Cheiroptera, 
and Primates. See also Breast and its sub- 
headings. Mamma and its subheadings, and Milk, 
secretion of.

allied to adenoma rather than sarcoma. It not 
infrequently follows injury, or the mastitis of 
suckling, and may grow to a large size, ulce- 
rating and fungating without implication of the 
lymphatic glands, and causing death by exhaus- 
tion. On section it is whitish, dense, lobulated 
or foliated, and containing many small cysts 
lined with epithelium, filled wilh a serous fluid, 
and frequently, especially the larger ones, pre- 
senting branched growths from their walls; 
these increasing distend the sacs, and protrude 
as a lobulated, bleeding fungoid mass.

influenced by climate, political condition, &c., 
whicli cci'tuinlj' operate on the physical consti- 
tution, and promote or hinder the advancement 
of civilization. 

Mm cliar'acters of. In a zoological point 
of view man is cliaracterised by the great size of 
the brain cavity connected with liis liigli degree 
of intelligence, the volume of the brain being 
about 1500 cubic ceutimeters, whilst even tlie 
gorilla is but little over 500. The occipital con- 
dyles approximate to the centre of the base of the 
skull, so that the head is nearly evenly balanced 
on the spinal column in the erect posture. The 
biorbital angle, open in front, formed by the two 
visual axes, varies from 40' to 50', and vision is 
horizontal. The muscles of the jaw have a re- 
latively small and feeble development. The chin 
is large and prominent. The vertebral column 
presents three curvatures, adapted to sustain the 
body in the erect position with the least possible 
fatigue ; the spinous processes, especially of the 
dorsal region, point backwards. The sacrum 
is wide at the base, thick, conical, and curved at 
the point. The thorax is wide transversely. The 
sternum is broad and flat. The upper limbs are 
supported and kept well apart by the clavicles. 
The terminal segments of the fore-limb or hand 
are specially adapted by having an opposable 
thumb for prehension and touch; those of the 
posterior limb are adapted for support. The 
distance between the tips of the lingers of the 
outstretched arms is equal to, or but slightly ex- 
ceeds, the height of tlie body. The muscles 
engaged in maintaining the erect position, as 
the gastrocnemii, the muscles of the thigh and 
buttock, and the erectors of the spinal column, 
are largely developed. Gestation occupies nine 
months ; the infant is helpless for several 
months. Man is gregarious, possesses the faculty 
of language, is capable of conceiving abstract 
principles, of acting in accordance with a sense 
of duty, and has in a high degree imagination 
and judgment. 

IW. In the grround. The Convolvulus 
pandurcdiis. 

M. of the earth. The same as M. in 
the ground. 

M., prehlstor'lc. The earliest traces of 
man may perhaps be discovered in the pleisto- 
cene, or even the miocene, strata of the ter- 
tiary period ; but the prehistoric period proper 
is divided into the age of unworked stone, 
the age of wrought stone, subdivided into a 
paleolithic and a neolithic period, the bronze 
age, and the age of iron. The former im- 
portance of tlint as an implement may be 
traced in its employment by the Egyptians in 
their processes of embalming, and by the Etrus- 
cans in their sacrifices; and of bronze in its use 
by the Greeks to cut the branches of the sacred 
■woods of Mount Ida. In modern times the Danes 
and Swiss have shown, from an examination of 
their alluvial regions, kitchen middens, and lake 
dwellings, that the use of stone, bi-onze, and iron 
instruments has followed in regular succession. 
The earliest skulls known are the dolicocephalic 
ones of Neanderthal, Canstadt, and Eguisheim, 
which wei-e contemporaneous with the mammoth, 
and were succeeded by those of the Cro-magnon 
race, contemporaneous with the reindeer, and 
also dolicocephalic. 

M., ra'ces of. One of the first classifica- 
tions, by a scientific man, of the races of man 
was made by LinnaMis, wlio admitted four varie- 



ties : the fair European ; the Asiatic with black 
liair, brown eyes, and yellowish skin ; the African 
with crisp curly hair, "black skin, thick lips, and 
ilat nose; and the American with tawny skiii, 
long black hair, and beardless chin. 

Dlumenbach made five primary divisions: the 
Caucasian, Mongolian, I'',tl]ioi)ian, Auu-rican, and 
Malay. 

Geoffroy St. Hilaire, in liis seccnd classifica- 
tion, distinguished the Caucasian, with oval face 
and vertical jaws, which he termed the ortho- 
gnatlious type ; the Mongolian, with liigli cheek 
bones, eurygnathous ; the Ethiopian, with pro- 
jecting jaws, prognathous; and the Hottentot, 
with widely separated molars and projecting 
jaws, termed eurygnathous and prognathous. 

Iluxley makes the nature of the hair the basis 
of his classification, dividing man into the ulo- 
trichi, or curly-haired races, and the leiotrichi, 
or smooth-haired ; the former are dark skinned, 
and usually dolicocephalous, and are represented 
by the Negroes and Papuans ; the latter he di- 
vides into the australioid, mongolioid, xantho- 
chrooid, and melanochrooid. 

F. MuUer's classification is essentially lin- 
guistic, but he also makes a primary division of 
the races of man, in accordance with the cha- 
racters of the hair, into smooth and woolly hair, 
with ultimate subdivisions into Mediterranean, 
Nubian, Dra vidian, Mongolic, Malay, American, 
Arctic, Australian, Caffre, African Negro, Pa- 
puan, and Hottentot. 

Topinard bases the divisions of man upon five 
characters : the nasal index, the nature of the 
hair, the cephalic index, the colour of the skin, 
and the height, and recognises nineteen races, 
namely the Esquimaux ; Eedskins ; Mexicans 
and Peruvians; Guaranis and Caribs ; Samoyedis, 
Mongols and Malay; Cunmerians, Scandinavians 
and Anglo-Saxons; Mediterranean and Semites; 
Australian and Indo-Abyssinians ; Foulahs and 
lied Barabras; Fins; Celts and Slavs; Iranians; 
Bosjismans; Papuans; Kaffirs; and Negritos. 

Weisbach makes three principal divisions of 
man according to the form of the head, and re- 
cognises long, short, and intermediate heads.

produce gastric irritation and vomiting, depres- 
sion and paralysis of the cardiac musculature, 
fatty degeneration of the liver, and an apoplectic 
condition with convulsions and paraljsis, fol-

Til., acute'. (L. acutus, sharp. F. manie 
aigu'e, m. suraiguc, delire aigu'e ; G. Tohsucht, 
Wuth.) It has been defined as a mental disease 
characterised by abnormal rapidity in the suc- 
cession of ideas, and by morbid excitability of 
the motor centres of the cerebrum. Its course 
is divisible into the initial stage, the stage of 
exaltation, the stage of fuior, and the stage of de- 
cline. The initial stage usually commences with 
symptoms of gastric disturbance, want of appe- 
tite, and constipation, accompanied by uneasi- 
ness and heaviness in the head, sleeplessness and 
general feeling of despondency. The duration 
of this stage is commonly two or three months, 
rarely a few days, and still more rarely more 
than three months. The second stage, of exal- 
tation, commences by the patient feeling and 
looking better; he is animated, and sets to work 
with pleasure ; his ideas quickly succeed each 
other; he talks constantly, has illusions of sight 
and of hearing, as well as of the other senses, and 
may have hallucinations, believing he holds high 
office, or is pursued by persons of distinguished 
rank. There is great insensibility in regard to ex- 
posure to heat and cold, the calls of appetite, and to 
fatigue. Sleepisbrief and disturbed. The tem- 
perature is normal ; the pulse from 90 to 100. This 
stage may last for weeks or for many months. It 
at length culminates in an acute attack of mania, 
characterised by incoherent delirium and great 
violence, the patient endeavouring to strike 
those around him and to tear his clothes to 
pieces. This condition may persist for months, 
or be interrupted by temporary relapses into the 
second stage, when these become longer tlie stage 
of decrease of the disease commences. This is 
heralded by general reduction of the excitement 
and by better sleep, and recovery is sometimes 
preceded by a slight melancliolic and hypochon- 
driacal state, or the disease may pass into incur- 
able chronic mania. 

Tit., acute' delirious. (L. deliro, to be 
crazy. F. maxie suraiguc, furcnr ; \. fremsia ; 
G. Tohsucht, Wuth.) An affection distinguished 
from acute mania by its sudden supervention, 
short course, and frequent grave issue. It may 
owe its origin to some violent mental shock or 
excitement, or it may occur in the course of 
some acute disease, as pneumonia, measles, or 
rheumatism, or after great fatigue, an epilep- 
tic fit, or childbirth. As a rule the patient, 
though highly excited, is not violent. He 
is hot and dirty. High temperature, brown 
tongue, prolonged slcephssiu'ss, and the occur- 
rence of visions of a horrible nature are un- 
favourable signs.

T/l,, danc'ing:. A delusion which arose in 
Germany and, reaciiing Aix-la-Chapelle in 1374, 
spread from that city to tho Netherlands. The 
attack, often induced by witnessing it in others, 
commenced with epileptiform convulsions, after 
which the patients, springing up, danced and 
sang, with violent contortions of the body, for 
hours together, until they fell completely ex- 
h;iusted. Whilst dancing their faculties were 
wholly absorbed, and no attention was paid to 
impressions on the senses. A tympanitic condi- 
tion of the abdomen followed the attack, accom- 
panied by pain in the belly, which was relieved 
by swathing them tightly with bands. In 
some instances complete and immediate recovery 
occurred ; in others, the patients becoming 
frantic dashed themselves against walls or flung 
themselves into rivers ; whilst others, again, re- 
mained permanently debilitated. Similar ma- 
niacal attacks have been recorded as occurring 
amongst the ancients, and were subsequently 
known ia Italy, where the affection was at first 
called Tarantistn.

pulse is small and rapid ; the feeces and urine 
are passed involuntarily ; nephritis and diar- 
rhoea occur ; from furious delirium the patient 
passes into muttering delirium, and in the course 
of from a few days to two or three weeks collapse 
supervenes, and death results in coma. 

IMC. hallucinato'ria. (L. hallncinatio, a

means of clastic bands ; a firm and even pressure 
is thus brought to bear upon the upper fragment 
which is kept in tolerably close apposition to the 
lower fragment of the j)atella.

(0H)5. A yellow, solid, sugar-like substance 
contained in manna, and on which its laxative 
virtues dejiend. It can be artificially prepared 
from certain kinds of sugar. It is also called 
sugar of manna. It is a hexatomic alcohol, 
isomeric with dulcite and raclampyrite, and 
identical with the substances formerly named 
granatin, fraxinin, primulin, and syringin. 
It is widely distributed in nature, being found 
in the exudation issuing from the punctures 
made by the Aphis euonymi in the spindle-tree, 
in the honey dew of the linden, in the exu- 
dations of many cherry and apple trees, larches, 
many Eastern oaks and palms, in (Ethiopian 
honey, in the roots of Aconittim napellus, 
Scorzonera hispanica, Meuin athamanticum, and 
many others, in the barks of Ganella alba and 
Phyllyrea latifolia, in the leaves and young 
branches of Syrifiga vulgaris, in the fruits of 
Zaurtcs, Olea, and Cactus, in some seaweeds, as 
Laminaria saccharina, and in many fungi. It 
frequently appears in the course of fermentation 
processes. Mannite crystallises from its watery 
solution in long, thick, rhombic prisms, and 



from its alcoholic solution in silky brushes or 
stidlate needles. Its sp. gr. is 1-187. It dissolves 
in about six times its weiglit of both hot and 
cold water. Its solution is optically inactive, 
but rotates pulariscd light to the left when 
caustic soda is added, ami to the right when 
borax is substituted. It was discovered in 
manna by I'must.

Slanom'eter. (MavJs, slack or thin; 
/utTiOoy, a measure. V . manomctre ; G. Manome- 
ter, Dichtigkcltsmcsscr.) Varignon's term for 
an apparatus whereby to measure the degree of 
I'arefaction of the air in pneumatic machines, 
and now generally used to designate an in - 
strumcnt for measuring variations of pressure; 
and so also for determining the pressure which 
gases or fluids exercise against the walls of 
vessels. The simplest form of the instrument 
used in physiological investigation is the 
straight tube of the original experiment of 
Hales, which was fixed on the blood-vessel 
and the height to which the column of blood 
was raised in its interior was noted. Two main 
forms are now in use, the U-shaped tube filled 
with mercury, as in Poiseuille's hannadynamo- 
meter, and the C-shaped spring, as in the 
kymographion of Fick. An elastic india-rubber 
bag is sometimes used, as in the pneumograph 
of Marey, 

IMC., coxu'pensatin§r, of IVCa'rey. 
{Marey. F. manomctre compcnsateur de Marey. ) 
In this form of the instrument the ascending 
tube presents, near its lower part, a capillary 
constriction, by which means the oscillations of 
the mercurial column are extinguished and the 
mean pressure accurately recorded. 

nx., frog:. An instrument devised by 
Ludwig for the study of the action of fluids on 
the excised frog's heart. It consists of a double 
cannula, one limb of which communicates with 
a self- registering U-shaped manometer, and the 
other limb with one or both of two Mariotte's 
flasks; to this he added a means of transmitting 
a galvanic current. 

tit., Magen'die's. In this form of mano- 
meter the short branch of Poiseuille's mano- 
meter in connection with the artery is replaced 
by a large flask partially filled with mercury 
and in part with a saline solution. Owing to 
the Lirgo surface presented by the mercury in 
the flask, as compared with that in the vertical 
tube, the displacement of the mercury in the

into the tube, leading from the heart to the 
mercnry ccdumn, of a cup-and-ball valve, which 
opens easily from the lieart, but closes firmly 
when liuid attenipts to return to the heart. By 
reversing the direction of the valve tlio ma- 
nometer is converted from a maximum into a 
minimum instrument. Difi'erential manometers 
are also employed. 

M., Fol'seuille's. In this fonn tlie two 
arms of the U-shaped tube are partially filled 
with mercury ; tlie shorter arm connected with 
the vessel is charged with a saline solution to 
jirevent coagulation. The longer arm is open to 
the air, and the oscillations of the mercurial 
column are clearly visible. 

IVI., registering. (F. manometrc in- 
scripteur.) The same as M., Poiseuilld s, with 
the addition, devised by Ludwig, of a small float

upper part of which is united at right angles a 
style, by means of whicli the oscillations can be 
registered <in a blackened plate.

partments by a diaphi-agni of thin iudia rubber; 
one compartment communicates with the gas 
supply of a burner, and the other with a wide 
tube having a mouthpiece ; the burner being 
lighted a vowel is spoken or sung into the mouth- 
piece, when a toothed tlamc of light will be exhi- 
bited by a rotating four-faced mirror ]daced

fertilising the soil ; usually applied to the 
fiecal discharges of horses and cattle and other 
animals, mixed with their bedding, but fish, 
woollen rags, and bones are included under the

accumulated in heaps near stables, mixed with 
straw, and constitute a valuable fertilising ma- 
terial when spread over the soil. 

Ma'nus. (L. manus, a hand ; from Aryan 
root ma, to measure. F. main; I. mano ; S. 
mano ; G. Hand.) The terminal segment of 
the anterior limb ; the Hand. 

In Pisces the manus is represented by the much 
segmented lateral rays forming the teitninal ex- 
pansion of the fin. 

In Amphibia the manus, when present, consists 
of four or five digits, or fewer, attached to five car- 
pal pieces, some of which may be fused together. 

In some Reptilia, as in snakes, the fore-limb 
and hand are entirely absent. In most cases, 
however, the hand is represented by five digits. 

In Aves the hand is bent backwards and much 
reduced in complexity, consisting of only two 
carpal bones, an elongated metacarpus, and three 
fingers, consisting of the pollex or thumb, bearing 
the so-called bastard wing, a middle finger, and 
a little finger. 

In Mammalia the manus or hand, characterised 
by an opposable thumb, varies much in develop- 
ment. It consists of a carpus, metacarpus, and 
digits. The number of digits is never moi*e than 
five, but may be reduced to four, as in the pig 
and tapir, by the disappearance of the thumb or 
innermost digit ; to three by the disappearance 
of the outermost digit or little finger, as in the 
rhinoceros ; to two, as in Ruminants, by the re- 
duction of the first, second, and fifth digits, the 
second and fifth remaining as small accessory 
claws, which do not touch the ground ; or even 
to one, as in the horse, when all the digits are 
suppressed, except the middle one. With the 
reduction of the number of digits the metacarpal 
bones belonging to them are either entirely ab- 
sent or are reduced to styliform bones, and the 
carpal bones are simplified.

M. senilis. (L. senilis, belonging to old 
ago. G. allgemcine Kriifteverfall, HimvelJcen.) 
The shrinking of the body which is observed to 
occur about the seventieth year, even with abun- 
dant food and the absence of any depressing con- 
ditions of mind or body, though it occurs earlier 
in the ill-fed and hard-worked members of the 
community. The chief phenomena are fatty 
degeneration and calcification of the vessels, 
leading to loss of elasticity, and liabilit}- to rup- 
ture of their coats and to aneurysms. The heart 
presents hypertrophy of the left ventricle, with 
or without dilatation, as a mechanical conse- 
quence of the increased resistance to the circula- 
tion of the blood. The arterial degeneration leads 
to softening of the brain, to senile gangrene of the 
extremities, to thrombosis, and to cmlwlisms. 
In consequence of diminished metabolism the 
production of heat, as well as its regulation, is 
enfeebled and impaired. The bones and carti- 
lages undergo atrophic changes and alterations of 
forms, occasioning the bearing, the height, and 
the phy.siognomj' of old ago. The lymphatic 



glands and spleen undergo atrophy. The muscle.s 
become weak and liable to rheumatic pains. All 
kinds of work are accomplished witb greater 
diffirulty. The skin becomes thinner and of a 
dirty yellow colour ; the hair of the head be- 
comes thinner, more silky, grey, and falls out, 
but the beard hair remains good. The teeth fall 
out, appetite fails, and digestion becomes im- 
paired. The lungs become small, the breathing 
shallower, and the respiratory interchanne of 
gases lowered. There is increased liability to 
coughs and colds, to bronchitis and pneumonia. 
The brain diminishes in size, the grey matter 
especially becoming thinner, with vacuoles. The 
powers of the will and memoiy fail ; the senses 
become blunted. There is a disposition to arcus 
senilis, cataract, atrophy of the optic nerve, 
and choroidal changes implicating the retina, 
and to deafness with noises in the cars. The 
kidneys become smaller, the quantity of urine 
less, but more highly coloured and containing 
more urea. The bladder loses some of its power 
of expulsion, and incontinence of urine may 
occur. The sexual power fails. The hright 
falls in successive decades from the thirtieth to 
the eightietb year from 172-2 cent, to 171 'S, 
167-4, 163-9, 162-3, 161-3 ; the weight from 68-9 
kilogrammes to 68-87, 77-45, 65-.50, 63-03, 61-22, 
and in the ninetieth year even to 57'83 kilo-

before the right eye with the left closed ; on 
looking steadily at the cross the circle is also 
seen ; on bringing the paper nearer to the face, 
the eye being still fixed on the cross, a place will 
be found where the cross will disappear, and will '

in the bee. Monogamy is not very rare. The 
Macacus silcnus has one female to whom he is 
faithful up to his death. In the guinea-fowl 
the male confines himself to one female. In 
some animals a real and moral monogamy exists 
of a remarkable character. Thus with the Pxitta-

vated swampy district, liable to floods ; a region 
from which the water never wholly drains 
away. When partiallj' dried, exhalations arise 
from such soils which give rise to remittent and 
intermittent fevers. The stagnant pools which 
abound in marshes frequently rest on clay beds, 
impervious to water, in which many mosses and 
alg;r, with some grasses and sedges and a few 
trees like the willow, find conditions favourable 
to growth. They are often fojtid, and bubbles 
of carburetted, piiosphnretted, and sulphuretted 
hydrogen and carbonic acid gas escape. They are 
ill adapted for the life either of man or of the 
domestic animals. The emanations are most

tubes, one of which is funnel-shaped at its outer 
end and passes to the bottom of the bottle, and 
the other just passes through the cork, is bent 
horizontally at the outer side and again upwards 
at a distance of five or six inches, where it is 
drawn to a fine point. Pure zinc is placed in 
the bottle, the cork is fitted, and dilute sulphuric 
acid is poured through the funnel into the bottle ; 
when the hydrogen gas has well developed and 
has expelled all the air, the solution to be tested 
is poured through the funnel, and the gas as it 
escapes from the narrow point of the outlet tube 
is lighted ; if arsenic be present it will burn with 
a bluisli tlame, smelling like garlic, and will de- 
posit a hair- brown stain of metallic arsenic or of 
a suboxide on a piece of cold white porcelain 
held near its point, having a white ring of crys- 
tals of arsenious acid around it, which may be 
dissolved and further tested.

Massircn.) The systematic, successive manipu- 
lation of a part or parts of the body by means of 
a combined rubbing, and pressing, and squeezing 
with the hands of the manipulator. The ditferent 
modes of performing the operation, or the forms 
of massage, have received different names. They 
are : Effleurage, a centripetal stroking movement 
with the palm of the hand or with the surfaces 
of the fingers or the thumb, with pressure iuter- 
mitting at a varying but somewhat rapid rate, 
both hands being employed one after the other 
in alternations of compression and relaxation ; 
Petrissage, a picking up of some portion of the 
skin and some muscular or other deep tissue with 
the thumb and fingers wide .apart, and squeezing 
or rolling it about, and proceeding rapidly from 
below upwards to successive parts; Friction, a 
process consisting of upward or rotatory rubbing 
movements with the palm of one hand and the 
tips of the fingers of the other; and Tapotemcnt, 
a rapid percussion of the cutaneous surface with 
the tips of the fingers, or with the ulnar border 
of the hand, or with the back of the half-closed 
hand, so that the vibrations may be communi- 
cated to the deeper structures. 
The beneficial action of massage is probably 



exercised chiefly through an improvement of the 
general processes of nutrition, consequent on the 
more active metabolism of the tissues, and the 
more rapid removal of the waste substances of 
the body, produced by tlie mechanical action of 
the compressing and relaxing movements, on 
the one hand, in emptying the veins and the 
lymphatics, and, on the other, in eflecting 
tlieir refilling from their origins in the capil- 
laries and the lymph-spaces ; but there is also 
reason to believe that massage in some of its 
forms is not without a beueficial inlluence on the 
nervous system, and that, not only directly by 
tending to produce quiet and refreshing sleep 
and to relieve painful sensations, but also in- 
directly by inducing a healthier condition of the 
nerves concerned in the regulation of the pro- 
cesses of nutrition.

Kicfcrmuskel.) A thick quadrilateral muscle, 
divisible into two parts. The superficial portion 
arises from the lower border of the anterior two 
thirds of the zygomatic arch, and runs down- 
wards and backwards to be inserted into the 
lower half of the ramus of the jaw. The deep 
part arises from the posterior third and deep 
surface of the arch, and descends vertically to 
the upper half of the ramus of the jaw and the 
coronoid process. It is supjilied by the masse- 
teric nerve, a branch of the third division of the 
fifth nerve, and by the masseteric branch of the 
internal maxillary artery. Its action is to raise 
the lower jaw. 

In some Rodentia this muscle is very large.

ments or to those of separation and approxima- 
tion of the teelh, by means of whicli fragments 
are torn off by the front teeth, divided by the 
canines, and pierced and partly broken down by 
the sliarp molars. 

In Herbivora, the movements arc much more 
free and various, and are divisible into those of 
propulsion, in which the lower jaw is thrust 
forward ; retropulsion, in which it is drawn 
back ; and diduction, in which it is moved 
from side to side. The food can only be bruised 
and pounded on one side at a time, in conse- 
quence of the lower jaw being narrower trans- 
versely than the upper, so that when the right 
molars of the upper and lower jaws are opposed 
those of the left side are not. The depression of 
the lower jaw is effected in part by its own 
weight, and in part by the action of the digastric 
muscle, and in addition in Solipedcs by a special 
muscle, the stylo-maxillary, which is a short 
branch of the digastric. 

Prsepulsion is effected by the masscter and 
external pterj'goid muscles. It is impossible in 
Carnivora, moderatelj' free in Kuminants and in 
Solipedes, still more so in the pig, and freest of 
all in llodeutia. Ketropulsion is effected by the 
temporal muscle. Diduction, or lateral move- 
ment, which is oblique in direction, is mainly 
effected by the alternate action of the ptery- 
goids.

Dlasti'tis. (Mao-Tos, one of the breasts. 
F. mastite; G.Milchdrusencntziindung.) Inflam- 
mation of the female breast or mammary gland. 

TtL., acute'. The inflammation may result 
from a blow, or from a chill, and often atFeets 
nursing women, and most frequentl}' if there be 
a sore nipple by which septic matter may be 
introduced ; it especially attacks the right mam- 
mary gland. By the inflammation and swelling 
of the excretory channels the out-flow of milk is 
obsti'ucted, the ducts in one or more lobes become 
distended, and the nipple may appear retracted ; 
this obstruction theory of its causation is not 
clearly established in all cases, and very probably 
in many, if not in most, instances it originates 
in a septic lymphangitis produced by a cracked 
nipple. The skin presents a flush of redness. 
There is considerable pain, and inflammatory 
fever is marked. Suppuration takes place in 
from one to three or four days, and the pus 
collects either beneath the gland or in it, or 
between it and the integuments. 

ns. apostemato'sa. ('ATroo-Tij/xa, an 
abscess.) A mammary or milk abscess. 

IVX. coc'cus. (KoKJcos, a grain.) A micro- 
coccus obtained by Kitt from the exsudation of 
the inflamed udder of a cow which, after several 
generations of pure culture, produced, when in- 
jected into a galactophorous duct, inflammation 
of the corresponding lobule of the gland. 

IVX., Interstit'ial. (L. interstitium, a 
space between.) The form which commences in 
the subcutaneous and interalveolar connective 
tissue, and is produced by bacterial infection 
generally proceeding from a cracked nipple or 
other skin excoriation ; occasionally it may occur 
as a pyaemic complication produced by an em- 
bolism containing microbes. It may be circum- 
scribed or difl'use, and ends usually in suppura- 
tion. The Streptococcus pyogenes is considered 
by Bumm to be the infecting agent, and in some 
cases, perhaps, the Staphylococcus pyogenes, S. 
aureus, and S. albus. 

M., interstit'ial, cir'cumscribed. (L. 
circumscribe, to draw a line around.) The form 
oi M., interstitial, which is limited in area and 
has a definite outline. 

ns., interstitial, diffuse'. (L. diftisus, 
spread out.) The form of M., interstitial, in 
which the whole gland is affected. 

IVX., lob'ular, Interstit'ial, chronic. 
(L. lobulus, a small lobe ; interstitium, a space 
between, chronicus, long-lasting.) Erichsen's 
term for a chronic interstitial inflammation of a 
limited portion of the mammary gland occurring 



in women beyond middle life and bearing some 
likeness to scirrhous cancer. It ap])ears as a 
rounded, fairly circumscribed, hard nodule, 
usually situated at the margin of the gland, 
which may grow to the size of a pigeon's egg, 
and become granular in outline ; it generally 
increases at the menstrual periods; it varies as 
to painfulness and tenderness, and as to the 
enlargement of the axillary glands. The con- 
nective tissue is the pai't originally affected, 
small round cells are developed in it, and Irom 
them dense fibrous tissue originates which com- 
presses the acini and the ducts, producing fatly 
degeneration of the epithelium and retention- 
cysts in the ducts. 

IMC. neonato'rum. (L. neonatus, newly 
born.) An inllammation of the mammary gland 
that occasionally occurs three or four days after 
birth. 

Ttl., parenchym'atous, {Wuptyxvixa,

wliich commences in the alveoli, or the gland, 
or the milk ducts, from infection by the milk, 
which contains a pyogenic material, usually the 
Staphylococcus aureus. 

Also, inflammation of the substance of the 
gland as distinguished from inflammation of the 
subcutaneous connective tissue and from retro- 
mammary inflammation. 

IVX., phleg^'monous, cutaneous. (L. 
phlcymone, an inflammation beneath the skin; 
cutis, the skin.) A small superficial inflamma- 
tion ending in abscess, which generally com- 
mences in the sebaceous glands of the areola.

lobules of the gland. 

IMC., su'pra-mam'mary. (L. stqjra, 
above ; mamma.) A term which includes both 
M., cutaneous, and M., sub- cutaneous, 

T/l., syphilit'ic. (Syphilis.) A gum- 
matous infiltration of one or more lobes of the

quired, but may occur in the course of heredi- 
tary, syphilis. 

wi., tuber'cular. (Tubercle.) Inflam- 
mation and frequently suppuration of the mam-
