IN AN EARLIER report1 it was stated that the causation of otomycosis is a controversial subject among otologists. It was suggested that an intelligent approach to this problem might be made by attempting to determine the mycotic and the bacterial floras of normal and of pathologic ears; that by correlating the fungous flora with the bacterial flora of these ears some basis might be obtained to enable one to determine the etiologic agent of otomycosis and, thereby, facilitate the proper treatment of this disease. The medical literature contains few reports of studies of the bacterial flora of the ears. Moreover, little work has been done toward correlating the bacterial and the fungous floras of either normal or infected ears. According to Salvin and Lewis,2 Mincheu and co-workers stated that there was little difference in the bacterial flora of pathologic auditory canals "as compared with that of normal ones and, therefore,
