    C. Double Perforation of the Membrana Tyrn/pani. In the foregoing work the author stated that he had seen no case in which the membrana tympani was per- forated at two points. Since that time, however, he has observed several such cases. The diagnosis was in two instances confirmed by post-mortem examination. Of four cases observed by Dr. Politzer, the appearance pre- sented in three is shown in the accompanying sketch, Fig. 6; namely, two large oval perfora- tions, one before and one behind the malleus handle, se]3arated from each other by a grayish-yellow bridge, formed by the handle and a remnant of the membrane extending from its end down to the inferior periphery. In Dr. Politzer's pathological collection I saw a pre- paration of such a membrane taken from a young man who had suffered for a long time from otorrhoea and died of phthisis pulmo- nalis. In another preparation, taken from a child who died of pemphigus tabescentium, the appearance differs from that above described. We find, namely, behind the manubrium a perforation two lines in diameter, and another as large as a pin-head in the lower part of the membrane, Fig. 7. A. M. Fig. 7.
