should repeatedly convince himself, by introducing the index 

 finger of his right hand into the rectum and that of his left 

 hand into the pelvis, that he can quite easily define the 

 outlines of the prostate and the seminal vesicles by a process 

 of palpation, and when he has completed the dissection he 

 should note that he has demonstrated that the visceral layer of 

 the pelvic fascia, which is single laterally, is cleft medially

 a middle and a lower layer, and the interposition of the 

 bladder and the prostate between the middle and an upper 

 layer. There are two compartments, therefore, in the sub- 

 stance of the fascia, a lower or posterior, which contains the 

 rectum, and an upper or anterior, in which lie the bladder, the 

 prostate, the seminal vesicles, and the lower parts of the ductus 

 deferentes.
