A survey has just been completed at the White Haven Sanatorium2 of the incidence of tuberculosis among anthracite miners coming to autopsy in the various institutions in Luzerne County. Of 541 cases in which autopsy was performed on miners, pulmonary tuberculosis was the principal cause of death in 21.3 per cent, whereas of 730 cases in which autopsy was performed on male nonminers of the same age during the same period in the same institutions tuberculosis was the cause of death in 8.9 per cent.
