LESSON XXXV. 

 THE TESTIS. 



THE framework of the testis (fig. 355) consists of a strong, tough, 

 fibrous capsule the tunica albuginea which is covered externally 

 by endothelium reflected from the serous membrane the tunica 

 vaginalis. At the back part of the organ, the tunica albuginea is 

 prolonged for some distance (8 mm.) into the gland to form the 

 corpus Highmori or mediastinum testis. From the under surface 

 of the tunica albuginea septa or trabeculse pass towards the corpus 

 Highmori, and thus subdivide the gland into compartments or lobules 

 (about 120 in number), with their bases directed outwards and
