10g 
and then every two hours. In‘twelve hours the animal.began to improve. 
On the following day he was much better, and tonics were thereupon 
substituted for the stimulants. The horse rapidly recovered, and was soon 
well again. 
POISONING BY PREPARATIONS OF ANTIMOMY. 
ANTIMONY is still not uncommonly administered to the horse in the forms- 
.of tartar emetic and butter or chloride of antimony, which often constitute 
main ingredients of the recipes for balls and powders in the possession of 
stablemen and grooms. Antimony preparations are not nearly so frequently 
given as they once were, and: the practice is no doubt becoming still 
more rare. The late Mr. D. Gresswell had a large number of cases of 
poisoning by these agents under his care in the course of his lifetime,. 
and the writer has had a few examples, which fortunately, however, did 
not prove fatal. ‘ 
When a horse -has had a large dose, there are manifested frequent 
attempts at vomiting, and this may actually occur. The pulse becomes 
weak, fluttering, and almost imperceptible. There is great prostration, and 
gradual loss of consciousness in severe cases, followed by death. 
POISONING BY OPIUM. : 
OPIuM is not a common cause of poisoning in the horse, but it is sometimes: 
given by dealers and others in poisonous doses, in order to prevent kicking 
and restiveness in horses they wish to sell. A few months ago, the writer 
attended a half-bred mare to which the owner had administeréd one ounce 
-and a half of Turkey opium. When called in on the day following the 
administration of the drug, the mare was found to be in a very dull, dejected 
condition, and the pulse was very feeble and soft. The pupils of the eyes 
were contracted to pin points, and the membrane lining the nostrils was of a 
‘darkish brown hue. The symptoms remained unabated for three days,. 
during which time the animal continually moved round and round in the 
box. On the fourth day, the pulse began to regain vigour, but recovery was 
not complete before the lapse of a week. 
MERCURIAL POISONING. 
THE next agent of which we shall speak is a.very poisonous preparation of 
mercury called corrosive sublimate. . It is sometimes given by stablemen in 
injurious doses to horses, causing loss of appetite, salivation, pawing, looking 
at the flanks, rolling about, profuse perspiration, rapid and weak pulse,. 
violent action of the bowels, straining, convulsions, and death. On no 
account whatever should this excessively dangerous drug be used.
