ICehoe The Kettering laboratory College of Medicine-Bden Avenue University of Cincinnati Cincinnati IQ, Ohio Dear Dr. Kehoe: Thank you for the several reprints and booklets which you cent me. I look forward to reading them. I, too, was disappointed that we did not meet when you were here. I have toIked to Clarence Dillard since and he says that one of your engineers will probably come down to help organise the plant in a more hygienic way. I only hone that the workers con learn to take better care of themselves. Although I failed to answer your last letter, I did heed your warnings and advised the Willards to discharge those employees with blood leads at toxic levels. As I have written you before, so far we have been lucky and have had no serious irreversible damage. There are still two things that puzzle me which the pamphlets which you sent may help to clear up: One is the difference in absorp tion rate apparently of different individual^ and the other is the reaction of different individuals to the same blood lead level. It has also been a disappointment to me that anemia, stipp^ng, coproporphyrin, history and physical examination, etc. have been of so little use in picking out those who ore in danger. The length of time employed, to j*udge from my small experience, has also been of little significance. But, as you say, the ideal to strive for is no absorption of lead at all. Again, thank you for your letters and your interest and help in the oroblem here. Cordially yours,
