506 ALPHABETICAL SUMMARY. 
Leaves the stable limping ; returns bettered by exercise. Sickle hocks, 
or cow hocks, are said to be most subject. 
Treatment.—View the suspected joint from before, from behind, and 
from either side. Afterward feel the hock. Any enlargement upon the 
seat of disease, to be felt or seen, is a spavin. Feed liberally, and rest 
in a stall. When the part is hot and tender, rub it with belladonna and 
opium, one ounce of each to an ounce of water. Apply a poultice. Or 
put opium and camphor on the poultice. Or rub the spavin with equal 
parts of chloroform and camphorated oil. The heat and pain being 
relieved, apply the following, with friction: Iodide of lead, one ounce; 
simple ointment, eight ounces. 
SPECIFIC OPHTHALMIA. 
Cause.—The fumes of impure stables. 
Symptoms.—A swollen eyelid; tears; a hard pulse; sharp breathing ; 
a staring coat; a clammy mouth; the nasal membrane is inflamed or 
leaden colored; the lid can only be raised when in shadow. The ball 
of eye reddened from the circumference; the pupil closed; the iris lighter 
than is natural. The disease may change from eye to eye; the duration 
of any visitation is very uncertain; the attacks may be repeated, and 
end in the loss of one or both eyes. If one eye only is lost, the remain- 
ing eye generally strengthens. 
Treatment.—Remove from the stable and place in a dark shed. Open 
the eye vein, and puncture the lid if needed; put a cloth saturated with 
cold water over both eyes. If the horse is poor, feed well; if fat, sup- 
port, but do not cram; if in condition, lower the food. Sustain upon a 
diet which requires no mastication. Give the following ball twice daily: 
Powdered colchicum, two drachms; iodide of iron, one drachm; calo- 
mel, one scruple; make up with extract of gentian. So soon as the ball 
affects the system, change it for liquor arsenicalis, three ounces; muri- 
ated tincture of iron, five ounces. Give half an ounce in a tumbler of 
water twice daily. See the stable is rendered pure before the horse 
returns to it. 
SPLINT. 
Causes —Karly and hard work; blows, kicks, etc. 
Symplom.—-Any swelling upon the inner and lower part of the knee 
of the fore leg, or any enlargement upon the shin-bone of either limb. 
On the knee they are important, as they extend high up. On the shin 
they are to be dreaded, as they interfere with the movements of the ten-
