ANTIMONY. 
The form chiefly used in canine practice is that known as Tartar 
Emetic, and is nearly exclusively administered for emetic purposes. 
Actions and Uses.—Alterative, antiphlogistic, sedative, aud 
emetic. Externally, it is a counter-irritant, and when absorbed 
produces the same effects in the dog as when administered by 
mouth, 
Antidote.—Tannic acid 
Doses.—As an alterative, antiphlogistic, and sedative, ; toz 
grains. 
Emetic, 1 to 3 grains. 
NUX VOMICA—STRYCHNINE. 
This drug is probably the most frequent source of poisoning in 
dogs. 
Actions and Uses.—In excessive doses, adeadly poison. Medi- 
cinally it is a tonic and nerve-stimulant, being especially valuable 
in cases of paralysis, chorea, and amaurosis. Excessive doses 
produce general rigidity, trembling, spasmodic muscular twitchings, 
extending to the glottis, diaphragm, and muscles of respiratioa, 
hence death by asphyxia. 
Post-mortem Appearances.—Redness and inflammation of the 
stomach and intestines (more particularly present when the 
animal has survived some time). In some cases, engorgement of 
the lungs, right side of the heart, and large bloodvessels; in 
others, an absence of blood in the latter, rigidity of the involuntary 
muscles, flaccidity of the voluntary ones. Congestion of the 
brain and membranes of the spinal cord. For some hours after 
death the body is stiff and straight, the limbs rigidly extended, 
the head thrown backwards towards the spine, the ears erect, and 
the tail carried straight out. 
Antidotes.—Decoction of tobacco; extract of hemlock; chloro- 
form. 
Dosés.-_Nux vomica pulv., 2 grains. 
Nux vomica extract, 3 to 1 grain. 
Strychnia, 3 to ¥, of a grain. 
Liquor strychnia,* 3 to 10 minims.

Actions and Uses.—In large doses, a narcotic poison. Medi- 
* Two fluid drachms of liquor strychnia contain one grain of the 
strycbnia.
