The ear in which the patient's hearing was the more defective was invariably selected for operation. The night before the operation the auditory canal was thoroughly cleansed, syringed gently with a solution of bichlorid, 1 to 1000, and occluded with a piece of iodoform gauze, which was allowed to remain in position over night. The drumhead was soaked for one hour before the operation in a sterilized 4 per cent. solution of cocain, by means of a pledget of sterilized absorbent cotton, which was saturated in the solution and inserted into the canal in contact with the drumhead.
