Its weight was 83 Ibs. A portion of umbilical cord about 3 inches in length was 

 still dangling from the umbilicus. Its fur was greyish yellow, mottled by darker spots, 

 suggesting leopard characters. 



Abdominal Viscera. On opening the abdomen, the general shape of the cavity was 

 seen to be ovoid, being wider in front and narrowing behind to the well-marked inlet 

 of the pelvic cavity. Regarded as a whole, the abdominal cavity presented a close 

 resemblance to that of the porpoise,* of which an account appeared in the Transactions 

 of the Royal Society of Edinburgh, vol. xl., part ii., p. 315. 



Running forwards from the umbilicus, the umbilical vein, already nearly obliterated, 

 formed a very distinct object, suspended as it was in the free edge of an extensive 

 ventral mesentery constituting the falciform ligament of the liver. Running back- 

 wards from the umbilicus, the urinary bladder, with its associated hypogastric arteries, 

 was likewise suspended in a mesial ventral mesentery whose depth from the abdominal 

 wall to the bladder measured from an inch to an inch and a half. The bladder was 

 long and narrow, and at the umbilicus its lumen was distinct. No part of the bladder 

 had become obliterated to form the urachus, so that the bladder represented the entire 

 intra-abdominal extent of the allantois. 



The liver and stomach occupied the wide anterior end of the abdominal cavity, and 

 in rear of them only the mass of coiled intestine was visible. 



PERITONEAL FOLDS AND REFLECTIONS. 



At first glance there was no sign of a great omentum, but on separating the coils of 

 intestine from contact with the stomach, the great omentum was found crumpled up 

 against its attachment to the greater curve of the stomach. Its greatest depth from the 

 stomach to its free margin was 3 inches. It was devoid of visible fat, and was there- 

 fore an extremely thin and translucent membrane. There was a well-marked gastro- 

 hepatic or lesser omentum presenting the usual gastric and hepatic connections. The 

 gastro-splenic omentum was also well marked, and by it the spleen was attached to the 

 great curve of the stomach. From the dorsal aspect of the spleen the peritoneal 

 membrane extended to the dorsal wall of the abdominal cavity without coming into 

 relation with the left kidney, which was situated opposite to its fellow and considerably 

 further back in the abdomen. 



The liver was attached to the sub-diaphragmatic surface by the usual suspensory, 

 coronary and lateral peritoneal ligaments, to which further reference will be made in 

 describing the liver.
