downwards. It is lined every where with a con- 

 tinuation of the cuticle from the oesophagus. In 

 the Porpoise the oesophagus enters the superior 

 end of the stomach. In the Piked Whale its en- 

 trance is a little way on the posterior part of the 

 upper end, and is oblique. 



The second stomach in the Piked Whale is very 

 large, and rather longer than the first. It is of 

 the shape of an Italic S, passing out from the up- 

 per end of the first on its right side, by nearly as 

 large a beginning as the body of the bag. In 

 the Porpoise it by no means bears the same pro- 

 portion to the first, and opens by a narroAv r er ori- 

 fice ; then passing down along the right side of 

 the stomach, it bends a little outwards at the 

 lower end, and terminates in the third. Where 

 this second stomach begins, the cuticle of the 

 first ends. The whole of the inside of this sto- 

 mach is thrown into unequal rugas, appearing like 

 a large irregular honey-comb. In the Piked 

 Whale the rugse are longitudinal, and in many 

 places very deep, some of them being united by 

 cross bands ; and in the Porpoise the folds are 

 very thick, massy, and indented into one another. 

 This stomach opens into the third by a round 

 contracted orifice, which does not seem to be 

 valvular. s 



The third stomach is by much the smallest, and 

 appear to be only a passage between the second 

 and fourth. It has no peculiar structure on the 

 inside, but terminates in the fourth by nearly a&
