The following are the lengths of the alimentary viscera :— 
_ Small intestine, 26 feet 2 inches. 
Large intestine, 9 feet 10 inches. 
Cecum, 1 foot 3 inches. 
The stomach, in shape, is very much lke that of R. unicornis as 
figured by Professor Owen. Its cardiac surface is lined with the 
smooth white squamous epithelium found in all the Perissodactyla. 
This occupied about one third of the total gastric area, extending 
along most of the lesser curvature, the rest being covered with a

valve like that found in the Horse. 
The small intestine is somewhat larger in the duodenal region than 
elsewhere. Its first three inches are destitute of the flattened papille 
found elsewhere; but here, as all along the small intestines, minute 
villi are present everywhere. Three inches from the pylorus the 
papillee commence, and resemble those similarly situated in Rhinoceros 
unicornis,* except that they are not quite so long. They are repre-
