OF THE SPERM WHALE.

Those parts which respect the nourishment of this 
tribe do not all so exactly correspond as in land ani- 
mals, for in these one in some degree leads to the other. 
Thus the teeth in the ruminating tribe point out the kind 
of stomach, coecum, and colon, while in others, as the 
horse, hare, lion, etc., the appearances of the teeth only 
give us the kind of colon and coecum ; but in this tribe, 
whether teeth or no teeth, the stomachs do not vary much , 
nor does the circumstance of coecum seem to depend on 
either teeth or stomach. The circumstances by which 
from the form of one part we judge what others are, fail 
us here, but this may arise from not knowing all the 
circumstances. 
The stomach, in all that I have examined, consists of 
several bags, continued from the first on the left towards 
the right, where the last terminates in duodenum. The 
number is not the same in all ; for in the porpoise, 
grampus, and piked whale, there are five— in the bottle- 
nose, seven. Their size respecting one another differs 
very considerably, so that the largest in one species may, 
in another, be only the second. The two first, in the 
porpoise, bottle-nose, and piked whale, are by much the 
largest— the others are smaller, though irregularly so. 
The first stomach has, I believe, in all very much the 
shape of an egg with the small end downwards. It is 
lined everywhere with a continuation of the cuticle from 
the oesophagus. In the porpoise the oesophagus enters 
the superior end of the stomach. In the piked whale its 
entrance is a little way on the posterior part of the upper 
end, and is oblique. The second stomach of the piked
