HANNA, PAVILION Dr. Robert Kehoe Kettering Institute of Toxicology Cincinnati, Ohio Dear Doctor Kehoe: I am trying to assemble some representative data regarding the ratio ^'concentration in brain in hmans or in experimental lead concentration in blood animals -who have elevated blood levels of this element. I am particularly anxious to get ratios in young animals or humans and in adults. We are searching the literature for this infor mation, but I thought that you might have run across data of this type. May I say, in closing, what a pleasure it has been to read your most comprehensive chapter, in Tices Medicine, on lead poisoning. Many thanks. TGB/bjs T. George Bidder, M. D K 0019911
