Symptoms.—Thickened skin; cracks; and sometimes ulceration.
Treatment.—Wash; dry thoroughly; apply the following wash: Animal glycerin, half a pint; chloride of zinc, two drachms; strong solution of oak-bark, one pint. Mix. If ulceration has commenced, rest the horse. Give a few bran mashes or a little cut grass to open the bowels. Use the next wash: Animal glycerin, or phosphoric acid, two ounces; permanganate of potash, or creosote, half an ounce; water, three ounces: apply six times daily. Give a drink each day composed of liquor arsenicalis, half an ounce; tincture of muriate of iron, one ounce; water, one pint.
CRIB-BITING.
Cause.—Sameness of food and unhealthy stables, or indigestion.
Symptoms.—Placing the upper incisors against some support, and, with some effort, emitting a small portion of gas.
Treatment.—Place a lump of rock-salt in the manger; if that is not successful, add a lump of chalk. Then damp the food, and sprinkle magnesia upon it, and mingle a handful of ground oak-bark with each feed of corn. Purify the ventilation of the stable before these remedies are applied.
CURB.
Causes.—Galloping on uneven ground; wrenching the limb; prancing and leaping.
Symptom.—A bulging out at the posterior of the hock, accompanied by heat and pain, often by lameness.
