Professor A. N. Winchell, of the University of Virginia, has called our attention to some inconsistencies in our paper "Crystalline Salts of Dihydrostreptomycin" (Science, 1949, 109, 515). In the section describing the microscopic examination of crystalline dihydrostreptomycin sulfate, the following correction should be made: Lines 30 and 31 should read: "2V (calculated) 89°; extinction, parallel and/or oblique; extinction angle 18°" instead of "2V (calculated) –89°; extinction, parallel; extinction angle –18°."
