The membrana tympani in health and disease : clinical contributions to the diagnosis and treatment of diseases of the ear, with Supplement . be seen in front of the manubrium, be-hind it a smaller, irregular, polygonalone, which strongly contrast with thebluish gray color of the other parts ofthe membrane. Several oblong reflec-tions of light are seen at the lower end of the to his own and his mothers statement, noaffection of his ear had ever been noticed. The hearingdistance upon this side is, indeed, somewhat less for thewatch than upon the left, but for speech it is just as more interesting is the condition of the membranatympani in Mr. M—r, a student.

In the casesjust mentioned, nothing can be saidwith certainty concerning the manner in which thesedeposits originated. The sketches immediately following represent patho-logical preparations, taken from persons whom I ex-amined during life. Fig. 3 represents the inner side of the left membranatympani of a girl, twenty-four years of age, who died ofphthisis in the clinical department ofDr. Kolisko.
