body of the epididymis are, therefore, only loosely attached 

 to the testicle and these permit, under some circumstances, 

 of wide separation from the gland. Thus in cryptorchidy in 

 the horse, the gubernaculum, as shown in Fig. 1, crosses the 

 tail of the epididymis and is closely attached to it. In enter- 

 ing the inguinal ring, the tail of the epididymis, with the 

 gubernaculum, must lead and physiologically the tail of the 

 testicle must accompany it. But sometimes the caudal end 

 of the testicle becomes caught at the ring, the tail of the

epididymis, followed by the body, and even the head, passes 

 through the ring, the testicle turns upon its transverse axis, 

 and its head becomes incarcerated in the inguinal ring, its 

 caudal end remaining within the abdomen. The inexperi- 

 enced surgeon attempts to castrate the cryptorchid, en- 

 counters the epididymis in the peritoneal pouch and am- 

 putates it from the testicle under the impression that he is 

 castrating the animal. Later a second operation is neces- 

 sary and within the abdomen there is found a "third testicle."
