OF THE SUMATRAN RHINOCEROS. 135 
With regard to the size of the stomach, the greater curvature is 
62 inches in length, and the lesser 6 inches; the greatest breadth from 
side to side, including the cardiac diverticulum, is 26 inches; the 
greatest depth is 18 inches; and the length of the diverticulum is 11 
inches, whilst it is 5} inches in diameter. The diameter of the undis- 
tended cesophagus where it enters the stomach is 2 inches, and of the 
commencing duodenum 1} inch. There is not a trace of enlargement 
of the duodenum at its pyloric end, like the considerable dilatation in 
the Indian species. A large portion of the pyloric portion of the 
stomach is situated beyond, or to the right of, the pylorus itself; but 
it is only a direct continuation of the cavity of the viscus, and hardly 
forms a true cul-de-sac. The great omentum, which does not cover the 
intestines, is of considerable size; it contains no fat, and is not in any 
way attached to the colon, but runs up, behind the stomach, free to 
the vertebral column. 
The interior of the stomach presents a similar condition to that 
found in the Tapir and Horse, the mucous membrane being of entirely 
different characters in the cardiac and pyloric portions. That in the 
cardiac end, and in its diverticulum, is much plicated in all directions, 
and has a white opaque appearance; while the pyloric portion is 
covered with a thick and apparently smooth mucous membrane of the Page 97.
