CHIEF CLINICAL RESEARCH h HYSK.IA*- April 10,, 1956 Dr. Robert A. Kehoe University of Cincinnati The Kettering Laboratory Eden Avenue Cincinnati 19, Ohio Dear Dr. Kehoe: Following up my discussions with you in Cincinnati at the time of the Subcommittee meeting, our management has agreed that it would be acceptable if you inform the Ethyl Corporation of our interest in learning about the toxicity of trimethyl ethyl lead. This is still very much in the developmental stage, so it would be greatly appreciated if this interest could be maintained in as small a group as possible outside of our company for the present. Sincerely yours,, 7?. R. E. ECKARDT, M. D. RSE:mak
