u Anti-pyretic Effect of Quinine, in the Treatment of Pneumonia 
in the Horse.” While I fully agree with the gentleman, with 
regard to the value of quinine in the treatment of that disease, I 
cannot see that he has demonstrated its good effect, in his case, 
from the fact of his having given it in such extremely small 
doses. And in conjunction with it, he gave aconite and Dover’s 
powder, both of which lower internal temperature. When an ani¬ 
mal with a high temperature is placed under the influence of the 
three above-named drugs, I would think it a rare case if the tem¬ 
perature was not affected, and 1 do not think it would be within 
any person’s power to say which one of three produced the 
effect. 
Since I have been connected with the hospital department of 
this institution, I have seen a great number of cases of pneu¬ 
monia, especially the past few months. In the largest and best 
kept boarding stable in this city it prevailed as an enzootic, and, 
all affected, having a temperature above 104° F., were treated 
wholly upon quinine and ammonia carbonate. There were twenty 
odd horses sick, and only one of that number died, that being 
complicated with bronchitis and pleurisy. I have noticed that in 
uncomplicated cases of pneumonia, quinine very readily lowers 
the temperature, while if bronchitis is associated with it, the anti¬ 
pyretic effect is not as quickly obtained. 
Dunn, in his work on Veterinary Therapeutics, gives the dose 
of quinine for a horse, as from grs. x to grs. xx., that is, a good 
tonic dose, but I do not think that quinine given in that dose to a 
horse, will have any effect upon abnormal temperature in the 
least; men have been known to take grs. xl., at a dose, without 
bad results following; in the horse I have never seen its toxical 
effect produced, but I will venture to say, that 3 vi. will not pro¬ 
duce it on animal of 1200 lbs. weight. The following are reports 
of four cases; two of which were patients in the hospital, and 
two outside. 
Case Ho. 1.—On the 28th of December called to see a large 
grey gelding, used for hack purposes. This horse had double 
pneumonia—more extensive in the left lung. Treatment pre¬ 
scribed was ammonia carbonate, and poultice to the sides
