In the stallion after a similar incubation, the penis and usually 

 the sheath become swollen and congested and if free from pig- 

 ment there are dark points as described in the vulva. These 

 points become firm, prominent, and finally vesicular and pustular. 

 If continued in service the resulting sores may extend and prove 

 protracted. In the absence of service they tend to heal about the 

 fifteenth day. The eruption may extend on the scrotum, the 

 inner side of the thighs, the throat, the lower surface of the 

 neck, and the inside of the forelegs ; on any parts indeed that 

 may become soiled on mounting the mare. The meatus urinarius 

 is red, swollen and angry, and shows a mucopurulent discharge. 

 Generative excitement is shown by the more frequent rising and 

 falling of the testicles, protrusion and retraction of the penis, 

 and the frequency of urination. 



In bad cases in both sexes the eruption encroaches more widely 

 on the skin, and subcutaneous abscesses may form on the vulva, 

 anus, tail, between the thighs or on the scrotal, mammary or 

 inguinal regions. These are attended by extensive local swellings 

 extending on the croup, or down to the hock, or forward to the 

 hind limbs. In such cases there is more or less stiffness or 

 lameness, with constitutional disturbance, hyperthermia, gastric 

 disorder and emaciation. 



Diagnosis. This disease is distinguished from dourine by the 

 known absence of the latter from the locality, by the ready 

 transmission, of the benign exanthema to cattle, by the entire 

 absence of paresis or mental hebetude, by its rapid progress and 

 early recovery, usually in fifteen days. 



Treatment consists in thorough cleanliness, and the application 

 of cooling, astringent, antiseptic lotions to the affected parts. 

 Solutions of borax, boric acid, sulphate or chloride of zinc, perman- 

 ganate of potash, corrosive sublimate, chlorine water, creolin, 

 lysol, carbolic acid, or other such agent with glj'cerine will act 

 promptly and well. In the severe cases with secondary abscesses 

 the latter must be opened and the cavities treated antiseptically. 

 Cooling laxatives and diuretics with salicylates or hyposulphites 

 may also be desirable. 



Preventioii. No animal having sores nor discharge from the 

 generative organs should be used for breeding. The owner of 

 the animal infected by breeding has a good claim for damages.
