    fox resembles, was examined by J. Adams. Haller, Krause, Prevost, and Dumas. They were the earliest workers in this interesting field of scientific inquiry. In the year 1840, the prostatic secretion of the dog, was examined by Buxmann. The last-named investigator describes it as contain- ing, besides the bases potassium, calcium, and sodium, the chemical combinations metaphos- phoric acid, sulphuric acid, and chlorine. The albuminous receptacle varied between 45 per cent, and 92 per cent., and the contents of sodium chloride amounted to one per cent.* XIII. Blood Supply of the Prostate Gland; Nerve Supply. The arterial blood supply of the prostate gland of the red fox, though minutely distrib- Figure 13. Prostatic capsule, red fox. uted, is yet derived from but few vessels. These are three in number, as follows: a. The internal pudic artery, a branch of the anterior trunk of the internal iliac artery. b. The inferior vesical artery, also a branch of the anterior trunk of the internal iliac artery. c. The superior hemorrhoidal artery, the continuation of the inferior mesenteric artery. The blood supply of the prostate enters by way of the gland capsule. From the capsular blood-vessels branches are given ofif which penetrate the septa throughout the gland. ♦Oppel’s LeJirhuch cler Vergleichenden Mikroskopischeti Anatomic cler Wirbeltiere, vol. IV., Jena, 1904, p. 359. Each compartment or lobule is enclosed in a delicate capillary plexus. The veins of the prostate form a plexus around the sides and base of the gland (pubo- prostatic plexus). In front they communicate with the dorsal vein of the penis; posteriorly they terminate in the internal iliac, vein. The lymphatics of both halves of the pros- tate gland in the red fox are identical in ar- rangement. They begin as a fine network sur- rounding the acini. These find their way to the surface of the organ, where they combine to form larger vessels. After passing through the chain of lymphatic glands in this situation, the lymphatic vessels of the prostate join with the lymphatics from the bladder, and enter the internal iliac glands. The nerves of the fox's prostate are de- Figure 14. Prostatic urethra, anterior part of prostate. Note absence of peri urethral erectile tissue. Red fox. a.

They are connected with the sec- ond, third, and fourth sacral spinal nerves. Single nerve-cells, some of exceptionally large size, are frequently seen in the prostate gland of the red fox. XIV. Microscopical Structure of the Prostate Gland. Five specimen blocks of the prostate gland of the red fox were made—one from the ter- mini of the vasa deferentia and four from the prostate gland proper, as follows:
