of the Cavities which constitute the Stomach of the Whale. 95 
termination of the oesophagus. It is surrounded by several 
semicircular doublings of the internal membrane : the broadest 
of these is on the lower part, these are thick, and appear to 
be glandular. 
There is a canal between the first and second cavities 3 
inches long, which opens into the second by a projecting 
orifice, and the cuticular covering of the first stomach termi- 
nates immediately beyond this orifice, which is 2 j- inches in 
diameter. 
This second stomach is nearly spherical, about 7 inches in 
diameter. Its internal surface has a honeycombed appearance, 
formed by soft ridges of a glandular structure, leaving inter- 
stices of some depth between them. This structure gives the 
coats a considerable degree of thickness. 
The opening into the third stomach is almost close to 
that which enters the second, and is only J- of an inch in 
diameter. 
The third cavity is nearly spherical, and is 2 inches in dia- 
meter. Its internal surface is smooth, and there are every 
where small orifices of ducts of glands opening into its cavity. 
The aperture, which communicates between this and the 
fourth stomach is f of an inch in diameter. 
The fourth cavity is nearly cylindrical like an intestine, but 
rather widest at its furthest extremity. It is inches long ; 
its greatest diameter is 3 inches. The internal membrane is 
smooth, and for 3 inches towards its origin, and 4 inches 
towards its termination has numerous orifices through which 
secretions are poured into the cavity. The pylorus, which is 
the boundary of this stomach, is a round orifice ~ of an inch 
in diameter.
