Dr. R. Xehoe, M.D., University of Cincinnati, Department of Preventive Medicine and Industrial Health, Kettering Laboratories, College of Medicine, Eden Avenue, CINCINNATI 19, OHIO. Dear Dr. Kehoe, Thank you for your letter of May 12th, -with its kind invitation to visit you in Cincinnati. I am grateful for your comment that you do not consider- that lead is likely to have any significant association with cancer, and that this is not the direction of your research into lead compounds at present. I think;it would be wiser, therefore, to defer rry visit until some time when I may have more definite evidence. / Thank you for your inviiation and look forward to the possibility of visiting you at some future date when I shall be less rushed. Tours sincerely. ^3- , Dr. A. C-. Cettle. Head : Cancer Research Unit of the National Cancer Association of S.A. 01 p. r; "? U/0
