ESCHAR
—is the prominence remaining upon the cicatrix of an ill-cured wound, or the scab frequently seen to form a projecting apex upon a broken knee; or where some injury has been left to cure itself by an effort of nature, without the least interposition of art. If it is a scab only, and not of long standing, it may in general be brought away spontaneously, by occasional softenings with small quantities of camphorated spermacæti liniment; if, on the contrary, they are rigidly seated, and have acquired a degree of callosity in the nature of a sitfast, there is no other mode of cure, but by extirpation with the knife and forceps.
