An Inquiry into tiie Reasons why the Horse rarely Vomits.

III. What is the action of Emetics on the Horse? 
It is so well known among veterinary pathologists, that the 
horse is not acted on by emetics as is the dog, that, while 
they frequently prescribe them in the disease of the latter, 
they never do so in those of the former. The most celebrated 
writers on veterinary therapeutics, generally exclude emetics 
from the list of medicines available for the relief of the 
diseases of the horse, and refuse to the emetic, par excellence , 
—the potassio-tartrate of antimony,—any emetic virtue in 
the equine species, when administered internally. Were this 
the sum total of our information on the point at issue, our 
inquiry would be at an end; but since it has been alleged by 
several French experimentalists, that the horse makes efforts 
to vomit when potassio-tartrate of antimony is injected into 
its veins, it is imperative that we should test the empirical 
grounds of such allegation. 
We find it stated by M. Dupuy that he has succeeded in 
producing attempts to vomit in the horse, by injecting tartar 
emetic into the crural or jugular veins, in doses varying from 
six grains to two drachms. The director and professor of 
the Veterinary School at Lyons, in their account of the 
action of tartarised antimony, thus express themselves: 
“ Injected into the veins of the large herbivora, in doses of 
from nine to eighteen grains, tartar emetic occasions vomiting, 
or the phenomena which accompany that act of evacuation.” 
They give no evidence to prove this statement. 
Finally, we have Jo quote an experiment which was per¬ 
formed by MM. Leblanc and Mignon: “ Thirty-six grains 
of tartar emetic injected into one of the jugular veins of a 
horse,— a longitudinal opening .about seven inches long, 
made on the side of "fe^e line.a alba,—exploration of the 
stomach with the finger,—^extractions of the viscus insen¬ 
sible,—contraction of the abdominal muscles alternating 
with that of the diaphragm, the latter taking place during
