March 9, 1959 Mr. J. R. Sabina Technical Manager '-~T Petroleum Chemical Division Organic Compounds Division du Pent de Nemours & Co Wilmington 98, Delaware Dear Mr. Sabina: You and your associates may have wondered what has become of me lately In view of my silence and my failure to supply you with information on various matters of mutual interest. By this message I shall hope to let you know that 1 have not neglected my obligations, but rather have chosen among them the one task that seemed most urgent. On returning home after our interview in Washington D.C., with Dr. Magnusen, certain of his associates, and his Special Committee, 1 went to work on a memorandum or report of our work in the general subject of our discussion, and, despite the interruptions occasioned by other unavoidable duties, I have managed`to complete a reasonably adequate (I hope) statement of the problems involved and the evidence from experience and experiments, which bears on them. The report is now being reproduced and will be available in a few days. It is the first and only time such a report has been made, and I have believed that the facts should be so stated and documented as to be proof 1against challenge. Consequently spent almost as much time, effort and care on it as I would have devoted to a small monograph. The report will be bound in the usual form of reports from The Kettering Laboratory. All of the above, by way of explanation of the nature and scope of the document, which I hope, will live up to my advance notice, I need now to know how many copies you and your associates will wish to have, and whether you wish me to send them to the designated persons or, as a lot, to you. The considerable amount of information on the lead alkyls has been assembled by one of the members of our staff, and will be shortly in such form, with some comments from me, as to serve your purpose. I believe you will recognize that this information will not give us any of the real answers to the hygienic problems. I have taken the position that no such answers can be obtained by toxicological investi gation in the laboratory, but rather, that the practical hazards can be appraised only by observing and measuring the exposure associated K f 0003394 Mr. J. R. Sabina -(2)- March 9, 1959 with operations carried out on a small scale, under conditions which will not subject anyone to a continuing, unknown hazard. Sincerely yours, RAK;ss Robert A. Kehoe, M.B. 0003335
