The malformations which have given MOMMM for tin- ussump 1 

 of hermaphroditism are of ntoiv fi-. .pient occurrence in the male. 

 The\ are attributable to the fact that the processes of tu-ion which 

 normally take place arc interrupted. Wo then have a genital 

 member, \\liicli ordinarily is rudimentary, along the under side of 

 which there runs only a furrow in>t-ad of the urethra, a malforma- 

 tion uhich is designated as hypotpadicu. With this morphological 

 detii-ieiu'v may be united, secondly, an urn -.-I of the normal descent 

 of the testes. The latter remain in the body-cavity, and the genital 

 ridges thus acquire a great similarity to the labia majora of the female. 



III. The Development of the Suprarenal Bodies. 



The discussion of the suprarenal lodi- bed fellows that of the 

 uioirenital system. For, aside from the fact that the Miprarenal 

 bodies and the genito-urinary nri:an> are in all Vertebrate- very 

 closely connected spatially, they al>o appear to stand in verv rlu-n 

 i el at ion to each other in the history of their development. At least 

 the recent investigations of WELDON, JANOSIK, and Mm M.KOVICS 

 point that \vay, and are perhaps also suilicient to suggest the dii> ction 

 of the })h\>iol'>-i ( -;il research by which one can acquire an explanat ion 

 concerning the ever problematic function of these bodies. 



As is well known, there are to be distinguished in the suprarenal 

 bodies two different substances, which in Mammal- are <le>cril>ed, 



'iding to their mutual relation-, as medulla and cortex. 

 in\c-ti- ribe to them a double origin. BALFOUR, BHAI v

 cells and nerve-fibres grow in from the sympathetic, but that the
