vorous animals. In the Piked Whale, the length from the 
ftomach to the caecum is 28 yards and an half, length of caecum 
feven inches, of the colon to the anus two yards and three 
quarters. The fmall inteftines are juft five times the length 
of the animal, the colon with the caecum a little more than 
one-half the length. 
Thofe parts that refpedl the nourifhment of this tribe do not 
all fo exactly correfpond as in land animals ; for in thefe 
one in fome degree leads to the other. Thus the teeth in the 
ruminating tribe point out the kind of ftomach, caecum, and 
colon ; while in others, as the Horfe, Hare, Lion, &c. the 
appearances of the teeth only give us the kind of colon and 
caecum; but in this tribe, whether teeth or no teeth, the fto- 
machs do not vary much, nor does the circumftance of caecum 
feem to depend on either teeth or ftomach. The circumftances 
by which, from the form of one part we judge what others 
are, fail us here ; but this may arife from not knowing all the 
circumftances. The ftomach, in all that I have examined, 
confifts of feveral bags, continued from the firft on the left 
towards the right, where the laft terminates in duodenum. 
The number is not the fame in all ; for in the Porpoife, Gram- 
pus, and Piked Whale, there are five ; in the Bottle-nofe 
feven. Their frze refpe&ing one another differs very confidera- 
bly ; fo that the largeft in one fpecies may in another be only 
the fecond. The two firft in the Porpoife, Bottle-nofe, and 
Piked Whale, are by much the largeft; the others are fmailer, 
although irregularly lo. 
The firft ftomach has, I believe, in all very much the fhape 
of an egg, with the fmall end downwards. It is lined every 
where with a continuation of the cuticle from the oefophagus. In 
the Porpoife the oefophagus enters the fuperior end of the fto-
