CANTHARIDES.
Are the basis of the most approved and useful blister. In blistering, the hair should be cut or rather shaved off close, then rubbing in the ointment well for at least 15 minutes, repeating it every day until it does its work. After it has acted you may relieve the torture of the animal by the application of olive oil or lard. In deep seated sprains or inflammations, the blister should not be discontinued too hurriedly. An infusion of 2 ounces of the flies in a pint of oil of turpentine for several days is used as a liquid blister, and when sufficiently reduced with common oil, is called a sweating oil, and gradually abates or removes old or deep inflammation or cause of lameness.
