RABIES. 547 



in the healod wound and tore it with its teeth into a large ulcer. This 

 was healed by local treatment in ten days and the horse was kept 

 nnder surveillance for over a month. On the advice of another prac- 

 titioner the horse was taken home and put to work, and within three 

 days it developed violent symptoms and had to be destroyed. 



Diagnosis. — The diagnosis of rabies in the horse is to be made from 

 the various brain troubles to which the animal is subject; first, by the 

 historj^ of a previous bite of a rabid animal or inoculation by other 

 means; second, by the evident volition and consciousness on the part 

 of the animal in its attacks, offensive and defensive, on persons, ani- 

 mals, or other disturbing surroundings. The irritation and reopen- 

 ing of the original wound or point of inoculation is a valuable factor 

 in diagnosis. 



Recovery from rabies may be considered as a question of the cor- 

 rectness of the original diagnosis. Rabies is always fatal. 



Treatment. — No remedial treatment has ever been successful. All 

 of the anodynes and anesthetics, opium, belladonna, bromide of pot- 

 ash, ether, chloroform, etc., have been used without avail. The 

 prophylactic treatment of successive inoculations is being used on 

 human beings, and has experimentally proved efficacious in dogs, but 

 would be impracticable in the horse unless the conditions were quite 

 exceptional.
