CANKER
—in the ear of a dog, is mostly occasioned by injury from bushes in beating or hunting covert, and might be easily cured at first with a little Friar's balsam, or tincture of myrrh: this being omitted, a rigid eschar forms upon the surface, when which is separated by accident (as it repeatedly is) it leaves the wound larger than before. A very slight touch with the butter of antimony, is the surest and best mode of destroying the foundation of inveteracy, and healing the wound.
