individual was 11*50 inches and of the lesser curvature 7'80 inches, with a maximum
diameter of 1**10, The total length of the small intestine was 45"-60, and of the
large intestine 15"* 60. There is a small conical dilatation of the large intestine
on the beginning of its left wall. The first five inches of the small intestine are
considerably dilated and the mucous coat is smooth, but beyond that, to the large
intestine, there are long tracts in which it is thrown into long continuous wavy
parallel rugae of different calibre, but of marked regularity. The liver is rather small
compared with JB. lineata, and its right and left lobes lie immediately behind the
septa, its right being but little larger than its left lobe. The latter has a lingulate
anterior surface directed backwards and inwards, from left to right, with the
tip recurved outwards, the peritoneal sac being alone attached along the upper
border. Its outer half lies across the oesophageal portion of the stomach, the
recurved inner end resting in the depth of the smaller curvature. This lobe has
two small lobules at its base, dorsal to the attachment of the gastro-hepatic omentum,
and they also lie in the smaller curvature, the smaller lobule being bent anteriorly
over the root of the other, and fitting into the lesser curvature., The other lobule
contracts rapidly and in the middle line is not more than 0-75 of an inch in breadth
antero-posteriorly, while its transverse width is three inches. The two vence ca/oce
run along the anterior surface of this connecting lobe (lobulus cauclatus), the heart
resting on it about its middle. The right section of the liver is deeply concave,
chiefly by the inward projection of the ventral half of the right lobe which is
broadly bifurcate at its extremity, and to which the allantoic bladder is attached,
and by the dorsal half of this lobe meeting the lobulus quadratus at right angles.
The lobulus quadratus sends down a long filamentary process from its inner margin,
behind the gall duct, and along it the vena cava passes. The gall bladder which is
large is so deeply imbedded in the right lobe that its fundus appears on the external
surface of the liver as a round projection close to the margin between, the two
divisions of the right lobe. The bile duct has a course of about six inches, and
opens into the intestine, six inches from the pylorus. The bile is a very dark-green,
almost approaching to black.
The pericardium was full of a very clear fluid which measured about 2 ounces.
The right auricle was beating vigoronsly for about two hours after all external
signs of life had ceased, but the other cavities exhibited hardly, if any, perceptible
movements, any motions that they did make appeared more to be due to the blood
propelled by the right auricle and to its movements. The right auricle has thin,
almost transparent puckered walls and is considerably larger than the left auricle.
Its apex is directed inward, and slightly forward. The pulmonary artery divides
at O'68 inch from its base, and the brachial arteries arise one inch from the base
of the ascending carotid. The right descending aorta, lying between the pulmonary
artery and ascending carotid, bends over to the right nearly in a transverse direction,
crossing the left carotid, left and right bronchi, and bending round about the middle
of the left bronchus reaches the back. The right aorta gives off at 0*75 of an inch
from its base, a common trunk, a quarter of an inch in length, which divides into the
carotids and brachial arteries and then crosses the pulmonary artery and the right
bronchus. I t is about six inches long from the point it bends dorsaily to the bronchus,
and it gives off no branches in its oourse to its junction with the left aorta.
The latter, which is also six inches long in its dorsal course before it branches,
0-'2B above its junction with the right aorta, gives off two branches. One long
branch passes forwards to the left over the transverse colon to the concavity: of the
lesser curvature of the stomach, and enters the left lobe of the liver, but gives off no
branches until it reaches the stomach. The other branch passes forwards to the
right, crosses the dorsal aspect of the pyloric end of the stomach and then runs
along the gastro-hepatic omentum to the right, and backwards to the right of the
.quadrate lobe of the liver, to supply the liver pancreas and also the pyloric end of
the stomach and duodenal portion of the intestine, sending a few branches to the
.commencement of the large intestine. The mesenteric branches of the ccelic .Tig
arise by a short common tube about two lines in length, from which they radiate.
Commencing from above, the first branch is small and proceeds to the transverse
colon; the next in order to the right, two in number, viewing the animal from above,
are directed outwards to the duodenum, spleen, and pancreas. The next branch
passes to the ileum, while the two remaining and most posterior branches are
directed to the jejunum and to the last part of the great intestine. All these mesenteric
artenes thus pass off, anteriorly to the right, and posteriorly to the union of the
two aorta!. The suprarenal arteries are distant 3'75 inches from the point of union
of the right and left aortas, and the renal arteries are 0'68 below them, but anterior
to the supra-renals; backwards to the renal arteries nine small renal branches pass off
from each side of the aorta to the kidneys. The division of the aorta into its iliac
branches occurs two lines below the renal branch.
The ovaries in the virgin are narrow bands 0”'16 broad by 2''2B in length, their
lower ends curved forwards. On the right side, as well as on the left, two large processes
of the lung lie in front of the ovaries, as'in Batagurs generally, and on the
former side, the last part of the duodenumis closely attached to the side of the upper
part of the rectum and to the lung. The omental fold from this portion of fie small
intestine invests the pendent portion of the lung. From the oviduct to the rectal
attachment of the ligament of the ovary, a delicate fold of peritoneum stretches and
is attached along the under surface of the ligament, and can be traced along the
abdominal wall as far forwards as on a line with the lower margin of the liver, and
which gives attachment to the oviduct, which is 6'-25 in length by little more than
O’ OB in breadth. The trumpet-like mouth of the ovary dilates at its free extremity
to 0"*25 in breadth.
The intestine terminates about half an inch above the arched membrane that
passes forwards and downwards from its orifice on to the lateral walls of the cloaca,
when contracted closing in the arched membrane that protects the orifices of the
ureters and bladder from the faeces. The former arch of membrane when closed
only allows of a passage to and from the lateral cloaca! bladders. The intestinal
recess of the cloaca is thrown into longitudinal folds, while the urinary recess is
