STATE OF CALIFORNIA DEPARTMENTOF PUBLIC HEALTH WILTON L. HALVERSON. M.D. DIRECTOR OF PUBLIC HEALTH 64.8 Phelan Building December 29, 1952 DIVISION OF ENVIRONMENTAL. SANITATION 7 6 0 MARKST STREET SAN FRANCISCO2 CALIF. Dr. Robert A. Kehoe The Kettering Laboratory College of Medicine - Eden Ave. Cincinnati 19, Ohio Dear Dr. Kehoe: Thank you very much for sending me the copies of your papers on air pollution, as well as the printed manuscripts. I have read these papers with a great deal of interest and return the typewritten copies herewith. The questions that will probably be before our legislature on air pollution next year will not deal so much with the estab lishment of regulatory programs as with provision for a more vigorous research effort to measure the physiological effects on animals of the type of smog which is occurring in Los Angeles and some other California cities.
