On diphtheria immunity in North Greenland 1932–33
1. 304 natives of North-west Greenland were examined with standardized Schick toxin, and 139 with direct smears stained by the methods of Gram and Bie. 2. Of these 98 gave positive, 143 negative, and 63 doubtful reactions to the Schick test. 51 showed a positive control reaction with heated toxin. T...
