A New Method of Percussion.
—Dr. Kabierske, of Breslau, who fully recognizes the value of mediate percussion (by means of the plessimeter), has been studying the matter of immediate percussion, because it seems to him easier and more convenient, with a view to avoiding the numerous difficulties which attend the present method (Ther. Monatsh.—Med. Chir. Rund.). For this purpose he has devised an instrument similar to a tuning-fork, with the handle cylindrical and covered with rubber, and the blades rounded off at the ends. The handle of the instrument is held between the forefinger and thumb, and raised and lowered by them without moving the hand. Percussion is thus rendered easier of performance, because only one hand is required; the results are said to be more accurate, since among other advantages, much smaller surfaces can be examined at a time, the thickness of the blades being but 7 mm.
