A careful study of the position of the pancreas in a considerable 

 number of specimens reveals the fact that this, variation is dependent 

 upon, or at any rate, correlated with, the position of the duodeno- 

 jejunal flexure and the splenic flexure of the colon (cf. Figs. 7 and 4). 

 The duodeno-jejunal flexure is invariably in close contact with the 

 lower aspect of the inner half of the body, following it in all its 

 variations in position. Addison (1) has already called attention to 

 this intimate relation existing between pancreas and the duodeno-
