April 14, 1964 Re: #63071596 J. Ross Davidson, M.D., Chief Medical Officer Workmen's Compensation Board of British Columbia Vancouver, B.C., Canada Dear Doctor Davidson: In accordance with your letter of April 2nd, I am returning the file o f f 0 H H B H M N # 6 3 O 7 1 5 9 6 ) (together with the report of my review, and a bill for my services) by registered mail. Concerning the latter I am uncertain as to the financial policies of the Board, and 1 am prepared to abide by any rule or regulation of the Board that is applicable. I am in the habit of making charges for such services according to the usual procedure of the Kettering Laboratory (which I represent in this matter) of charging as nearly as possible for the cost of the services. ^ In this instance, I have spent more time in a detailed report on the issues than may have been required for your purposes, and I have limited the charges accordingly. The reason for this is that I could not bring myself to differ with Dr. Huckvale and some of the informants whom he cited, without fairly careful explanation. Moreover, in my opinion, based upon a fairly long and exacting experience in the clinical and experimental approach to the problem of occupational plumbism, there are so many conflicting and (if I may say so) erroneous views, that there is a crying need for clarification. Having set myself, a good many years ago, with the compulsory purpose of finding out what I needed to know to fulfill certain responsibilities for the safety of persons in certain lead trades, I have tried to get some firm answers to some obscure questions. This has been the basis for our systematic observations in industry and in the experimental laboratory, and some of those have borne good fruit, thanks to time, funds and competent assistants. It occurs to me in this connection that you and Dr. Huckvale might find good use for bound copies of a series of lectures, The Harben Lectures, which I gave on this subject, in London in 1960. In these, I attempted to condense the results of our experience for many years, into three lectures. These are, necessarily, packed with data, which I under took to present so as to illustrate the main facts without getting into certain matters which are still obscure. I am not sure that I accomplished my purpose, for the nature of these lectures made it impossible for me to cover the literature of the subject. However, certain facts have been established, through experimental procedures that have not been J.

If you are interested in these lectures I shall be pleased to forward them. Sincerely yours, RAK:vr Robert A. Kehoe, M.D. Enel. Report and Letter Dictated but not Read. P.S. On editing the first draft of my report, I find it somewhat less precise than it might be. I am compelled, however, to make only a few alterations, and to send it along, since otherwise it will be unduly delayed until I return from an unavoidable trip. If there are questions, please do not hesitate to inquire. I think, however, that I have made my position clear.
