An ivory plate of a circular or ovoid shape, from an inch and a half to two inches in diameter, and about one-sixth of an inch in thickness. It has either a raised rim or edge, or projecting handles on its upper side, to permit its being held between the finger and thumb of the left hand, whilst it is struck with the right. It is used in percussion of the chest. A piece of metal, a coin, or the finger of the left hand may be used with equal advantage.- See Percussion, mediate.
