154 Afr. Home ow the Structure of the Stomachs 
not appear to form a part of the receptacle for food. The 
internal membrane of the cardiac portion of the stomach, as 
far as the opening of the oesophagus, is an uniform surface, 
but immediately beyond, on the lower side or great curvature, 
there is a thick glandular substance of an oval form, bounded 
laterally by two prominent ridges, one on each side, with a 
similar one in the middle line of the stomach : there are also 
three smaller passing transversely from the middle to the late- 
ral ones. A small part of this glandular structure is situated 
in the pyloric portion, and where it terminates there is a row 
of large orifices leading to glands. These only extend round 
the upper part, and are not continued beyond the edge of the 
glandular structure. The pyloric portion has a smooth villous 
appearance. Vide Plate IX. 
No. XII. The Pecari. 
The stomach of the pecari differs from that of the common 
hog, in there being two processes at the cardiac extremity, and 
these having a more lateral direction ; so that the stomach ap- 
pears to be composed of three bags ; one the general cavity, 
the others the two lateral processes ; that which projects an- 
teriorly is nearly double the size of the other. The cuticular 
lining of the oesophagus extends further on the sides of the 
general cavity of the stomach than in the hog. 
XIII. The Elephant. 
This stomach is longer and narrower than that of most other 
animals ; the whole length is three feet three inches; and its 
diameter in the middle line, which is the widest part, is one foot 
two inches. The cuticular lining of the oesophagus terminates 
at the orifice of the stomach. The internal membrane of the 
stomach differs in appearance in different parts. At the cardia
