Dissection. 
Skin three quarters of an inch thick, with little adipose 
matter, and yielding no oil. 
The cavity of the abdomen large. 
The stomach is large ; and the relative position of the 
cardiac and pyloric orifices is nearly as in the human 
subject. It has two appendages, which open into it 
near the junction of the duodenum. Membrane of 
the stomach thick, internal surface smooth, and not 
corrugated into plies:. The stomach and its appen- 
dages were distended with fucus or sea-weed, but 
little masticated or altered. Intestinal canal long. 
Small intestines uniform. Caecum very large, some- 
what curved, and containing a portion of partially 
digested sea-weed. Colon exceeding the small in- 
testines in diameter by one third, very uniform, and 
with few or no contractions. Liver of moderate size, 
consisting of two large and distinct lobes, connected by 
a smaller one somewhat tongue-shaped, and a fourth 
which was very small, on the posterior side. Gall 
bladder little distended, and situated beneath the third 
and tongue-shaped lobe. Spleen very small, not ex- 
ceeding three inches long and one inch thick, attached 
to the left side of the stomach. Pancreas lying be- 
low the duodenum. Kidneys in their usual place, and 
large. Bladder much contracted, not exceeding the 
size of an egg, but from the thickness of its coats, is 
probably capable of much greater distension.
