is removed, the testes will be seen as two oval 

 bodies enveloped in a sheath of peritoneum, the 

 tunica vaginalis, within which is a white fibrous 

 membrane of connective tissue, the tunica albu- 

 ginea. 



2. The Epididymis is a convoluted mass of tubes 

 which lies external to the tunica albuginea. The 

 enlarged portion at the anterior end is the caput 

 epididymis ; it is connected with the testis by cer- 

 tain ducts. The posterior narrow portion is the 

 cauda epididymis, which at the posterior end of 

 the testis is continued as the vas deferens. 



3. The Vas Deferens is the continuation of the 

 canal of the epididymis ; it passes upward from the 

 testis along with the spermatic artery and vein. 

 These together form the spermatic cord and are 

 enclosed in a common sheath. The vas deferens 

 passes fonvard through an oblique opening in the 

 abdominal wall, the inguinal canal, bends around 

 the neck of the bladder, and enters the dorsal sur- 

 face of the urethra to form the urino-genital canal. 



4. The Prostate Gland is the glandular mass sur- 

 rounding the urethra at the point of entrance of 

 the vasa deferentia. 



5. Cowper's Glands are the two glands, one on 

 each side of the urino-genital canal, just beyond 

 the prostate. 



6. The Penis is the conical pointed organ sus- 

 pended from the wall of the abdomen by a fold of 

 the integument. It is composed of a median ven*
