THE TESTES. 



The testes are two glandular organs ; each is suspended in 

 the scrotum by the spermatic cord, which is attached to the 

 posterior border. Each testis consists of two parts : the body, 

 which is anterior, and the epididymis, placed posteriorly; to 

 the lower end of this latter the duct or vas deferens is attached. 



Coverings of the Testis : 



1. Serous or tunica vaginalis is derived from the peritoneum, 

 and consists of two layers, the visceral and parietal. 



2. Fibrous or tunica albuginea covers the body of the testicle, 

 sending in a vertical septum the mediastinum or corpus High- 

 ntori : this latter gives off secondary processes or septa, which 

 serve to separate the lobules of the testicle. 



3. Tunica vasculosa consists of the bloodvessels, connected 

 together with areolar tissue. 



The epididymis is a long narrow body, consisting of three 

 parts, viz. : a superior portion projecting forwards on the 

 upper end of the body, the head or globus major ; a lower, the 

 tail or globus minor, with which the vas deferens is continuous ; 

 and between these two, the body or central portion. The 

 epididymis consists of a duct 20 feet long, exceedingly con- 

 voluted, and bound together by areolar tissue ; it receives the 

 coni vasculosi at the upper part of the testicle. 



The body of the testicle consists of numerous lobules of 

 pyramidal shape, which are formed by trabeculae, mediastinum, 

 and tunica albuginea, the base of the lobule being directed 

 10 the circumference of the testis, and the apex towards the 

 mediastinum. Each lobule contains one or more tubuli semini- 

 /eri held together by areolar tissue. Each tubule commences
