1. Of 36,510 individuals X-rayed on 70 mm. minifilms, 35,306 (96.7%) were found to have normal chests. 2. Fourteen (0.13 %) Europeans were found to show evidence of active pulmonary tuberculosis. 3. Two hundred and thirty-one (0.9 %) non-Europeans showed evidence of active pulmonary tuberculosis. 4. The difference between the incidence of pulmonary tuberculosis in the different categories of workers is not considered significant, but the incidence in the different racial groups is believed to be statistically important.
