_Treatment._ First, separate the sheep; then cut off the wool as far as the skin feels hard to the finger; the scab is then washed with soap-suds, and rubbed hard With a shoe-brush, so that it may be cleansed and broken. For this use take a decoction of tobacco, to which add one-third, by measure, of the lye of wood-ashes, as much hog's lard as will be dissolved by the lye, a small quantity of tar from a tar-bucket, which contains grease, and about one-eighth of the whole, by measure, of spirits of turpentine. This liquor is rubbed upon the part infected, and spread to a little distance around it, in three washings, with an interval of three days each. This will invariably effect a cure, when the disorder is only partial. Or, the following: Dip the sheep in an infusion of arsenic, in the proportion of half a pound of arsenic to twelve gallons of water. The sheep should be previously washed in soap and water. The infusion must not be permitted to enter the mouth or nostrils. Or, take common mercurial ointment; for bad cases, rub it down with three times its weight of lard--for ordinary cases, five times its weight. Rub a little of this ointment into the head of the sheep. Part the wool so as to expose the skin in a line from the head to the tail, and then apply a little of the ointment with the finger the whole way. Make a similar furrow and application on each side, four inches from the first; and so on, over the whole body. The quantity of ointment after composition with the lard, should not exceed two ounces; and, generally, less will suffice. A lamb requires but one-third as much as a grown sheep. This will generally cure; but, if the animal should continue to rub itself, a lighter application of the same should be made in ten days. Or, take two pounds of lard or palm oil; half a pound of oil of tar; and one pound of sulphur; gradually mix the last two, then rub down the compound with the first. Apply as before. Or, take of corrosive sublimate, one half a pound; white hellabore, powdered, three-fourths of a pound; whale or other oil, six gallons; rosin, two pounds; and tallow, two pounds. The first two to be mixed with a little of the oil, and the rest being melted together, the whole to be gradually mixed. This is a powerful preparation, and must not be applied too freely. An erysipelatous scab, or erysipelas, attended with considerable itching, sometimes troubles sheep. This is a febrile disease, and is treated with a cooling purgative, bleeding, and oil or lard applied to the sores. SMALL-POX.
