ANATOMY AND PHYSIOLOGY 
whale is very large, and rather longer than the first. It 
is of the shape of the italic passing out from the upper 
end of the first, on its right side, by nearly as large a 
beginning as the body of the bag— where the second 
stomach begins, the cuticle of the first ends. The whole 
of the inside of this stomach is thrown into unequal 
rugse, appearing like a large irregular honeycomb. This 
stomach opens into the third by a round contracted 
orifice, which does not seem to be valvular : the third 
stomach is by much the smallest, and appears 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 as large an opening as its beginning. 
The fourth stomach is of a considerable size, but a 
good deal less than either the first or second. The in- 
ternal surface is regular but villous, and opens on its 
right side into the fifth by a round opening smaller than 
the entrance from the third. The fifth stomach is in 
the piked whale round, and in the porpoise oval ; it is 
small, and terminates in the pylorus, which has little of 
a valvular appearance ; its coats are thinner than those of 
the fourth, having an even inner surface, which is com- 
monly tinged with bile. 
The duodenum passes down on the right side very 
much as in the human subject , excepting that it is more 
exposed, from the colon not crossing it. It lies on the 
right kidney, and then passes to the left side, behind the 
ascending part of the colon and root of the mesentery, 
comes out on the left side, and getting on the edge of 
the mesentery becomes a loose intestine forming the
