RING-BONE.
Cause.—Dragging heavy loads up steep hills.
Symptoms.—A roughness of hair on the pastern and a bulging forth of the hoof. A want of power to flex the pastern. An inability to bring the sole to the ground only upon an even surface. Loss of power and injury to utility.
Treatment.—In the first stage apply poultices, with one drachm of camphor and of opium. Afterward rub with iodide of lead, one ounce; simple ointment, eight ounces. Continue treatment for a fortnight after all active symptoms have subsided, and allow liberal food and rest; work gently when labor is resumed.
RING-WORM.
Symptoms.—Hair falls off in patches, exposing a scurfy skin. The scurf congregates on the bare place about the circumference, which is apt to ulcerate.
Treatment.—Be very clean. Wash night and morning, and afterward apply the following ointment: Animal glycerin, one ounce; spermaceti, one ounce; iodide of lead, two drachms. Many other things are popular. For a detailed list of these, see the body of the book. A drink is likewise of use when employed with the ointment. Liquor arsenicalis, one ounce; tincture of muriate of iron, one ounce and a half; water, one quart. Mix, and give every night half a pint for a dose. Should the ulceration prove obstinate, apply permanganate of potash, half an ounce; water, three ounces. Or, chloride of zinc, two scruples; water, one pint. Moisten the parts with a soft brush six times daily. Feed well, and do not work for one month.
ROARING.
Causes.—The bearing-rein; the folly of fashion.
Symptom.—A noise made at each inspiration.
