vesicular exanthema, and which somewhat closely resembles horse- 

 pox. The benign character of the complaint and absence of con- 

 stitutional disturbance will distinguish either vesicular exanthema 

 or horse-pox from dourine. 



TREATMENT, to have any chance of success, should b.e under- 

 taken in the very earliest stage of the disease. We may frequently 

 apply to the sore parts some suitable antiseptic lotion, such as 

 creolin or carbolic acid (p. 67). Lingard's treatment of surra by 

 arsenic (p. 529) or intravenous injections (p, 531) should be tried. 



Opinions are divided as to the efficacy of castration as a means 

 of cure. 



SANITARY MEASURES.— Owing to the insidious nature of the 

 disease, and the small chance of effecting a cure, it is advisable 

 in most cases to destroy the animal ; although castration might 

 be tried in the case of a stallion which was but slightly affected. 

 An animal that has once manifested the disease should on no 

 account be again used for breeding purposes ; .because, not in- 

 frequently, apparent recovery takes place in animals in which 

 the seeds of the disease remain dormant for the time being, only 

 to develop later on with renewed vigour. The literature of the 

 subject gives us many instances of the use of an apparently 

 recovered stallion being the cause of the wide dissemination of 

 dourine.
