Box 403 Niagara Palls, New York Dear Doctor Eddy; Thanks for calling this obvious error on page 131 to our attention. All of us, of course, know that the arti ficial abrasives contain practically no crystalline free silica, but we all missed this implication in Edgar Mayer's introductory statement. I agree with you that a corrected statement should be made, but just how this should be done I am not sure at the moment. I'll be in touch with Henry Howe, on this in a few days. My best personal regards. Sincerely yours, L> .1' 0. A. Sander, M.D. S?? S ' OAS PH CC Henry P. Howe, M.D. American Medical Association Katharine R. Boucot, M.D. ug 0005395
