Treatment.—Three balls of sulphuret of ammonia, two drachms, with extract of gentian and powdered quassia, of each a sufficiency, may be given, one every half hour. Next, one ounce of chloride of potash, dissolved in a pint of cold water, and mingled with sulphuric ether, two ounces, should be horned down. In an hour's time, two ounces each of sulphuric ether and of laudanum; half an ounce of camphorated spirits; one drachm of carbonate of ammonia may be administered. No good effect being produced, throw up a tobacco-smoke enema. As a last resort, procure a stick of brimstone and light it. Remain in the stable while it burns, or the sulphureous fumes may become too powerful for life to inhale them. Continue this measure for two hours; then repeat the remedies previously recommended. All being fruitless, a desperate resort may be adopted. Puncture the abdomen with a trocar; but this operation can only be named here; the reader must turn to the substance of the book for its description.

WORMS

Are of four kinds: the Tænia, the Lumbrici, the Strongulus, and the Ascarides.

The Tænia mostly affect the young.

Cause.—Starving the mare when with foal, and breeding from old animals.

Symptoms.—Checked development; large head; low crest; long legs, and swollen abdomen. Appetite ravenous; body thin; coat unhealthy; breath fetid. The colt rubs its nose against a wall, or strains it violently upward; picks and bites its own hair.

Treatment.—Give spirits of turpentine. To a foal, two drachms; to a three months' old, half an ounce; six months, one ounce; one year, one ounce and a half; two years, two ounces; three years, three ounces; four years and upwards, four ounces. Procure one pound of quassia chips; pour on them three quarts of boiling water. Cause to blend with the turpentine a proportionate quantity of the quassia infusion, by means of yolks of eggs; add one scruple of powdered camphor, and give first thing in the morning. Good food is essential afterward. Subsequently give every morning, till the coat is glossy, liquor arsenicalis, from one to eight drachms; muriated tincture of iron, from one and a half to twelve drachms; extract of belladonna, from ten grains to two drachms; ale or stout, from half a pint to a quart.

The Lumbrici prey upon the old and the weakly.

Treatment.—Tartarized antimony, two drachms; common mass, a sufficiency to make one ball. Give one every morning.
