The author reported 12 cases of the so-called family streptomycin deafness, i. e. the family in which two or more deaf persons with hearing disorders due to the use of streptomycin were found, and following observations were performed:(1) Thirty-six persons in 12 families were examined, and in which 22 cases were exam ned audiologically.(2) In 36 cases, 4 cases were not streptemycin deafness, but the chronic progressive labyryn-thine deafness.(3) Previously, the author recognized that the individual differences in the occurence of stre-ptomycin deafness due to at least the inherent vulnelability of the hearing organ itself.(4) As the fact upon which this assumption were based, the author previously stated the indi-vidual differences in the occurence, progress and prognosis of the disease, symmetrical audiogram and family appearence, etc.(5) Now the author add one remark to it, that is a fact that in the same family we can find chronic progressive labyrinthine deafness and also streptomycin deafness at the same time.As the conclusion of this observation and consideration, the author maintain the inherent vul-nelability of the ear as the most important factor in the etiology of streptomycin deafness.
