50 THE DISEASES OF THE HO.RSE. 



29. Boro-glycerine, or boro-glyceride, is made of 92 parts 

 of glycerine to 02 of boric acid. Glycerine of carbolic 

 acid is made of 1 part of the acid to 4 of glycerine. 



A few fevers — more common to cattle than to horses — 

 appear in Part II. 



RABIES 



Is a nervous, febrile disease, originating in the dog, 

 occasionally in the cat, caused by a specific microbe (mite) 

 in the saliva of the rabid animal. Pasteur has demon- 

 strated that dogs and other animals inoculated with cul- 

 tivated virus do not take the disease when bitten by a 

 rabid dog, nor when inoculated with virus which would 

 kill unprotected animals. He also claims that the culti- 

 vated virus is usually protective, if used shortly after the 

 bite. (Dun.) Speaking of Pasteur's experiments Williams 

 says : "If rabies be not of spontaneous origin, and if the 

 experiments all turn out successful, there seems to be no 

 reason why rabies should not be entirely extirpated." But 

 lte thinks the disease is sometimes spontaneous. He fur- 

 ther say3 that Pasteur has succeeded " in rendering ani- 

 mals absolutely proof against the poison of rabies." 



Symptoms. — The disease is manifested in a variety of 

 ways. Sometimes there is great apparent distress, sudden 

 perspirations, unruliness, stamping and pawing violently, 

 and finally becoming frantic and dangerous. Sometimes 

 the horse will bite the wound, tearing the skin off; in- 

 tolerance of light, nervousness, eyes fixed and staring, 

 pupils dilated ; ears worked ; saliva abundant. There are 

 intervals of quiet between the fits, but they become shorter 

 and the fits more dangerous. 



Remedy. — When the disease is developed, there is no 

 cure, but excising the wound and then cauterizing it with 

 caustic potash or silver nitrate may possibly prevent its 

 development.
