VIII. Extravasation of Blood in the Penis. 



As a result of kicks, blows, or of forcible striking of the yard on the 

 thighs of the mare which it has failed to enter, the penis may become the 

 seat of effusion of blood from one or more ruptured blood vessels. This 

 gives rise to a more or less extensive swelling on one or more sides, followed 

 by some heat and inflammation, and on recovery a serious curving of 

 the organ. The treatment in the early stages may be the application of 

 lotions, of alum or other astringents, to limit the amount of effusion and 

 favor absorption. The penis should be suspended in a sling. 



IX. Paralysis of the Penis. 



This results from blows and other injuries, and also in some cases from 

 too frequent and exhausting service. The yard hangs from the sheath, 

 flaccid, pendulous, and often cold. The passage of urine occurs with les- 

 sened force, and especially without the final jets. In cases of local injury 

 the inflammation should first be subdued by astringent and emollient 

 lotions, and in all cases the system should be invigorated by nourishing 

 diet, while 30-grain doses of nux vomica are given twice a day. Finally, a 

 weak current of electricity sent through the penis from just beneath the 

 anus to the free portion of the yard, continued for ten or fifteen minutes 

 and repeated daily, may prove successful. 



X. Maladie Du Coit, or Dourine. 



This is propagated, like syphilis, by the act of copulation and affects 

 stallions and mares. It has long been known in northern Africa, Arabia, 

 and Continental Europe. It was imported into Illinois in 1882 in a 

 Percheron horse. 



From one to ten days after copulation, or in stallions it may be after 

 some weeks, there is irritation, swelling, and a livid redness of the external 

 organs of generation, sometimes followed by the eruption of small blisters 

 one-fifth of an inch across on the penis, the vulva, clitoris, and the vagina, 

 and the consequent rupture of these vesicles and the formation of ulcers 

 or small open sores. Vesicles have not been noticed in this disease in the 

 dry climate of Illinois. In the mare there is frequent contraction of the 

 vulva, urination, and the discharge of a watery and later a thick viscid 

 liquid of a whitish, yellowish, or reddish color, which collects on and soils 

 the tail. The swelling of the vulva increases and decreases alternately, 

 affecting one part more than another and giving a distorted appearance 

 to the opening. The affection of the skin leads to the appearance of circu- 

 lar white spots, which may remain distinct or coalesce into extensive 

 patches which persist for months. This, with the soiled tail, red, swollen, 

 puckered, and distorted vulva, and an increasing weakness and paralysis
