39° Mr. Home's and Mr. Menzies' Description 
smooth, without any appearance of glandular structure ; the 
anterior portion is more vascular and villous. At the pylorus 
there is an oval part of the internal surface of a dark colour, 
and rougher or more villous than the rest of the stomach, with 
a determined edge ; the small end of the oval extends about 
half an inch beyond the pylorus into the duodenum ; the larger 
end goes some way into the stomach, and extends chiefly over 
the posterior surface, also a little way beyond the great arch 
anteriorly, covering about half the breadth of this part of the 
stomach ; it is nearly as long again as it is broad. This part is 
probably glandular ; it was only seen in the young subject, 
which from the smallness of its size was more perfectly pre- 
served, and its internal parts better fitted for anatomical exa- 
mination. At the pylorus there is the usual thickened valvu- 
lar appearance. 
The stomach was entirely empty, and in a very flaccid state. 
The duodenum makes a considerable bend downwards on 
the right side before it crosses the spine, to become a loose in- 
testine ; there is no coecum or difference of size in the intes- 
tines, they are all strung upon the mesentery till within 15 
inches of the anus ; this part of the gut crosses the spine above 
the root of the mesentery, and passes down to the anus. The 
intestines have no valvule conniventes ; they were 52 feet long, 
which is 12 times the length of the animal. In a common 
otter, the intestines are only 3^ times the length of the 
animal. 
In a common otter two bags are found at the anus, but 
there are none in the sea otter. 
The mesentery is 7 inches broad, and its lower part, which 
may be called meso-rectum, is only five inches in breadth.
