five times the length of the animal, the colon 

 with the coecum a little more than one half the 

 length. 



Those parts that 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, &c. the ap- 

 pearances 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 the coecum seem to 

 depend on either teeth or stomach. The circum- 

 stances 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, con- 

 sists of several bags, continued from the first on 

 the left, towards the right, where the last ter- 

 minates in the 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 spe- 

 cies 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
