OFFICE OF THE SECRETARY 1108 MERCANTILE BUILDING Rochester, N. Y. . July 9, 1936 Dr. Robert A. Kehoe, College of Medicine, University of Cincinnati, Cincinnati, Ohio Dear Dr. Kehoej . I was over in Canada when your letter of July 1st came to hand and I note the reply which my office sent you. You sent me before a copy of the pamphlet on the Hormal Absorption and Excretion of Lead", so X am return ing one of the copies herewith. It certainly would be a shame to completely exhaust your own files and if you need the other copy, don't hesitate to ask me for it. I know how it feels to have one's own files strict down to bed rock. I note that you have an opinion that the ingestion of lead at least over a long period of.time in quantities greater than!'.milligram per day would probably not be advisable. How would you state that in terms of grains per pound of food or we will say per pound of apples? I suppose that would be a pretty difficult matter to arrive at. *If you had a single apple that weighed a pound and there was axe1 milligram of lead on it, that, of course, would be very simple, but apples of all sizes and weights and no one knows what quantity a person might consume in a day. The articles which you sent me came in yesterday and I shall examine them with great interest and will no doubt get in touch with you again as soon as I can get my bearings. Many, many thanks for your courtesy. With kindest regards, N9740
