　Torii and his associates report that a well established otogenic meningitis is cured by administration of large doses of penicillin following surgical treatment of the ear by radical mastoidectomy and open drainage of internal acoustic meatus which is supplemented with another open drainage of lumbar spinal canal. The patient is a girl 14 years of age, who developed otitis media that progressed to meningit's in 26 days from the onset. During the 70 days of the patient's total of 113 hospital days, 910,000,000 units of penicillin, 39 grams of urotropin, and 64.5 grams of sulfa coumpounds were administered in the treatment. In evaluating the factors which resulted in recovery of the case authors emphasize keeping open the channel of drainage from lumbar sbinal canal as of prime importance and though, penicillin in large doses was highly valuable, it is placed in the secondary role.
