HOMOEOPATHY IN VETERINARY PRACTICE. 
By Prof. C.JE. Sayre, M.D., D.V.S., 
(A paper read before the Illinois State Veterinary Medical Association.) 
As the majority of veterinarians have not investigated the 
history of homoeopathy and the principles of similia similibus 
curantur , I shall deviate somewhat from the subject in the first 
part of this paper and show that the principle of homoeopathy 
was recognized by the earliest writers on medicine. Hippocrates 
says: “ by similar things disease is produced, and by similar 
things, administered to the sick, they are healed of their dis¬ 
eases. Ihus, the same which will produce a strangury when it 
does not exist will remove it when it does.” The learned Dr. 
b rancis Adams, in his translation of the works of Hippocrates, 
published in 1849 by the Sydenham Society, thus comments 
upon this passage : 
The treatment of suicidal mania appears singular—‘ Give 
the patient a draught made from the root of mandrake, in a 
smaller dose than will induce mania.’ He then insists, in strong 
terms, that under certain circumstances purgatives will bind the 
bowels and astringents loosen them ; and he further makes the 
important remark that although the general rule of treatment be 
contraria contrariis curantur , the opposite rule also holds good 
in some cases, namely, similia similibus curantur. It thus ap¬ 
pears that the principles of both allopathy and homoeopathy were 
recognized by the author of this treatise. In confirmation of the 
latter principle, he remarks that the same substance which oc¬ 
casions strangury will also sometimes cure it, and so also with 
cough. And further, he acutely remarks that warm water when 
drank generally excites vomiting, but also sometimes puts a stop 
to it by removing the cause.” * 
Evidently Hippocrates had partially proved this drug 
(mandrake), and found it to produce mania, and had also used
