The cutaneous pouch, which contains the testes and spermatic cords, 

 is called scrotum; it is divided by a median external raphe into two 

 lateral halves ; the cavity of the scrotum is divided into two, by the Septum 

 scroti. Beneath the integument is the Tunica dartos, formed of unstrrped 

 muscular fibres, which is continuous with the superficial fascia of the 

 groin, perinaeum and inner side of the thighs. 



The seminal vesicles, Vesiculac scminales, are two lobulated 

 membranous pouches at the base of the bladder behind the prostata, 

 each having an upper obtuse and a lower pointed extremity, which latter 

 unites with the corresponding Vas dcfcrens, to form with it the ejaculatory 

 duct. The ejaculatory ducts, Ductus cjaculatorii, run between the 

 prostate gland and posterior wall of the prostatic portion of the urethra 

 forwards and downwards, and end in the urethra at the Caput gaUinaginis. 



The prostate gland, Prostata, has. the form of a chestnut and 

 encloses the first part of the urethra in such a manner, that the greater 

 part of the gland lies behind the urethra. The posterior surface of the 

 prostate is divided by two slight ridges into three lobes.
