(Poirier and Charpy.) The tubules are enclosed in a delicate plexus of capillary vessels, and are held together by an intertubular connective tissue, which presents large interstitial spaces lined by endothelium, which are believed to be the rootlets of lymphatic vessels of the testis. In this interstitial tissue are groups of large granular cells, the interstitial cells. These contain pigment, fat, and crystal- loids, and are more numerous before and after sexual activity. The aberrant ducts of the epididymis (ductidi aberrantes) are tortuous and end in blind ex- tremities. The superior aberrant duct (ductus aberrans superior) is in the globus major and joins the rete testis. The inferior aberrant duct (ductus aberrans inferior) (Fig. 1149). is in the tail of the epididymis, and lakes origin from the duct of the epididymis or the seminal duct. It is a persi-stent canal of the Wiilffian body. It extends up the cord for two or three inches and terminates liy a blind exlrcniity, which is occasionally bifurcated. It may be as much as fourteen inches in length when uin'avellc<l. Its structure is similar to that of the vas deferens. The descent of the testis will be described on page 1424. The Semen.—The semen is the viscid, whitish, or opalescent fluid, of alkahne reaction and characteristic odor, which is secreted by the testes, prostate, seminal vesicles, and Cowper's glands. It contains water artd about IS per cent, of solid matter, chiefly consisting of proteids, salts, and nitrogenous substances. The semen serves to convey and maintain the vitality of the spermia in their course along the seminal passages. The Spermatozoa, or Spermia, are present in enormous numbers in the seminal fluid. Each consists of a head, neck, body, and Please note that these images are e
