 testicle laid bare. It is to be noted that in all 

 cases of abdominal cryptorchidism, including

 has descended into the scrotum, the testicle, when 

 brought out, is naked; while in inguinal cryptor- 

 chidism, the testicle is inevitably brought out 

 covered by the cremasteric structures and the 

 parietal peritoneum.
