THE LYMPHATIC SYSTEM 



has been found provided with plexuses of lymphatics. In the bladder they form a rich plexus of 

 irregular capillaries which lie immediately under the almost intraepithelial blood-caj)illaries. 

 They connect, through the muscular layer, with a subserous plexus. The lymphatic plexus of the 

 urethra anastomoses with the capillaries of the base of the bladder, and in the male with those of 

 the glans penis. The lymphatic capillaries of the ductus deferens and of the seminal vesicles have 

 not been studied. In the prostate (Camineti) the lymphatics form rich plexuses surrounding the 

 glands, which connect with a very wide meshed subcapsular plexus, surrounding the entire 

 gland. 



In the testis there is a rich superficial plexus, lying directly beneath the tunica albuginea. 

 Concerning the deep lymphatics of the testis there has been much dispute. Ludwig and Thomsa

found tfio lymphatic capillaries going over into lacunie, without endothelium. This has heeiXg 

 disputed by Toinmusi and (jcrstcjr, who find, in the septa, capillaries with endotheUal wall| ■ 

 which they consider the Ix'ginniiigs of tlie lymi)liatics. 



In the fenuile, lymi)liatic ph^xuses have been found in the mucosa of vagina and hymen, 

 anastomosing with those of the vulva. In the nteriis, capillaries in the mucosa are very difficult 

 to demonstratf. Dcifinite lymphatics, liow(!V(;r, have Ix-eii found i)assiiig through the mus- 

 cularis, and under the jXTitoiieum a ricli subserous plexus of (capillaries is present. In the preg- 

 nant uterus these sub.serous capillaries are much distended (Schick). The Fallopian tubes are 

 provided witl' lymphatics, but they have not been carefully de.scribed.
