and thick digestive coat. There is no trace of any oesophageal 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 

 papillae found elsewhere ; b>it here, as all along the small intestines, 

 minute villi are present everywhere. Three inches from the pylorus 

 the papillae commence, and resemble those similarly situated in Rhino- 

 ceros unicornis^, except that they are not quite so long. They are re-

presented in fig. 1 (p. 708), where they are seen to consist of flattened, 

 round-tipped processes of the mucous membrane, several of which 

 are blended at their bases, in transverse lines. None are more than 

 •3 of an inch in length, and most about '6 inch broad where they 

 first become free. They give the impression of being incomplete 

 valvulse conniventes which have been cut and deeply jagged at their 

 free edges. The opening of the bile-duct is 7 inches from the 

 pylorus, being a nipple-like tubular projection, nearly an inch long, 

 among the papillge. From the spot where they commence, all the 

 way to the ileo-csecal valve, these papillae are found — those near the 

 last-named situation differing from those in the duodenum in being 

 more scattered and freer from one another, many in the ileum 

 springing independently from the mucous membrane. Nowhere,
