 The stomach was visible in the left hypochondriac region, the 

 liver appearing all across the abdomen. The great omentum did 

 not cover any of the viscera as now exposed ; it was attached only to 

 the upper part of the ascending colon, for about 2 inches. It con- 

 tained no fat, the animal being, it is to be remembered, considerably 

 emaciated. 



The stomach is of the usual Simian form, with a globular cardiac 

 cul-de-sac, and fairly distinct tubular pyloric part ; it measured 

 3 inches in length by" U deep. The pyloric constriction is distinct ; 

 and towards that part the walls become thicker. Internally there 

 is a distinct thick ridge on the lesser curvature, | inch to the right 

 of the oesophagus, dividing off the pyloric prat, which is quite smooth 

 internally, whilst the mucous membrane of the cardiac part has a 

 few irregular, slightly developed rugse. 



The length of the intestines is as follows : —

1 In Pifhecia satanas the transverse colon hardly exi.sts, the descending colon 

 beiuc bent sharply back upon the ascending. The cacum lay altogether to the 

 right of the descending colon and rectum ; the latter, therefore, was laot hidden 

 by it.
