CASTRATION OP CRYPTORCHIDS 23 



didymis with the other hand, guide the gland 

 through the ring with the introduced finger. 



Should we be unable to grasp the epididymis 

 outside the ring, we penetrate the ring with an 

 index finger, and, directing it backward, hook the 

 index finger over the gubernaculum as it leaves 

 the posterior margin of the ring, to immediately 

 lose itself in the tail of the epididymis. This is 

 grasped, drawn through the ring, and the opera- 

 tion then proceeds as before. 



Should the operator fail to locate the ring, he 

 needs at least to determine its approximate loca- 

 tion, penetrate the muscular wall as near to the 

 normal position of the ring as he can determine 

 with his index finger, and, palpating the surface 

 of the peritoneum, locate and grasp the guberna- 

 culum, and eventually the vas deferens. 



Theoretically, should the operator fail to locate 

 the testicle by this plan, he should next introduce 

 the entire hand into the peritoneal cavity, again 

 search for the gubernaculum, the epididymis, and 

 especially for the gland itself, and as a final re- 

 sort search for the vas deferens about the urethra 

 and trace it back to the gland.
