On the right of the oesophagus the cuticle does not end by 
a transverse line, but terminates first upon the middle line of 
the great curvature, where a villous surface begins by a point, 
and gradually encreases in breadth till it extends all round the 
cavity: its origin therefore is in the form of an acute angle. 
This villous surface is continued over the remaining cavity as 
far as the longitudinal bands extend : and that half of it next 
the pylorus has three rows of clusters of glands : one row 
is situated along the great curvature, and consists of 15 in 
number; the other two rows are close to the two longitudinal 
bands, and consist only of nine. Besides these there are two 
larger clusters of an oblong form, situated transversely, where 
the longitudinal bands terminate. The internal surface of the 
rounded cavity next the pylorus has a different structure, put- 
ting on a tesselated appearance, formed by a corrugated state 
of the membrane. Immediately beyond the pylorus is a ring 
of a glandular structure surrounding the inner surface of the 
duodenum. Vide Plate VIII.

The general form of the stomach is nearly that of the 
beaver; it is divided by a muscular contraction into two portions. 
The cardiac large and oval, its direction obliquely downwards ; 
the pyloric small and conical, its direction upwards. There is 
a process continued from the cardiac extremity, turned back 
upon the upper part of the stomach, which terminates in a 
blunted end. 
The cuticular lining of the oesophagus extends along the 
small curvature of the stomach in both directions, and termi- 
nates at the base of the process above-mentioned. This process 
is sometimes found contracted and quite empty, so that it does
