Penis. 



This organ, already studied to a certain extent, should now 

 be further examined. 



Dissect out the suspensory ligament (Lig. suspensorium 

 penis] and the dorsal vessels and nerves. 



PERITONEUM AND VISCERA. 



Developmental Relations. (Cf. Figs. 241-244.) 



Before beginning the study of the peritoneum, the development of the 

 coelomic cavities and the transitional stages in the mesenterium commune 

 should be carefully studied. Frequent reference should be made to Cun- 

 ningham, pp. 1054-1058; Poirier et Charpy, pp. 870-898. What are 

 the foregut, midgut, hindgut, and vitelline duct, and what relation does 

 this latter bear to the diverticulum occasionally found upon the ileum? 

 In what percentage of the cases is this diverticulum present, and how far 

 distant is it from the iliocaecal junction?
