340 A TREATISE ON HORSE-BREEDING. 



especially without the final jets. In cases of local injury the 

 inflammation should first be subdued by astringent and emol- 

 lient lotions, and in all cases the system should be invigor- 

 ated by nourishing diet, while thirty-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. 



SELF-ABUSEMASTURBATION. 



Some stallions acquire this vicious habit, stimulating .the 

 sexual instinct to the discharge of semen by rubbing the 

 penis against the belly or between the fore limbs. The only 

 remedy is a mechanical one, the fixing of a net under the 

 penis in such fashion as will prevent the extension of the 

 penis or so prick the organ as to compel the animal to desist 

 through pain. 



MAL DU COIT DOURINE. 



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

 and affects stallions and mares. It has been long known in 

 Northern Africa, Arabia and Continental Europe. It was 

 imported into Illinois in 1882 in a Percheron horse. 



Prom 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, some- 

 times followed by the eruption of small blisters, one-fifth of 

 an inch across, on the penis, the vulva, clitoris and vagina, 

 and the subsequent rupture of these vesicles and the forma- 

 tion 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 af- 

 fection of the skin leads to the appearance of circular white 

 spots, which may remain distinct or coalesce into extensive 

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