.WJ. V'V Dr. R.A. Kehoe. d a t * .. 26th July, 1949 -2- I would be grateful if you could let me have your present figures, which I feel must be the same or better than ours. 1 enclose a copy of the table of the means for the six months ending the 30th June, 1949 and also a table showing the rates of excretion by individuals arranged according to length of service. We are still using the short method on the plant. ^ think you will agree that the figures shown in one of the accompanying charts indicate that there is a close comparison between the 24 hour and snap samples done by the long and short methods respectively. We are checking some of results now with a Hilger-Nutting spectrophotometer on the plant. I still cannot understand why we are not getting more contamination, as there is a little lead in the atmosphere. Also it does not show itself in lead in air analyses but is definitely in dust collected in the laboratory. Our new laboratory at Lostook Green should be open in September. Dr. Greaud, who has been appointed as full time medical officer at Ethyl Kuhlmann at Paimboeuf, and who is also, I understand, to supervise the some fifteen active blending plants in Prance, is to come here in September, but we have not yet been given the dates. I enclose copies of the following literature, in which you might be interested: "Industrial Rehabilitation Unit" from the British Medical Journal. "Ethyl Petrol". Annual Report of the Chief Inspector of Pactories for the year 1943 Translation. "The Toxicity of Tetraethyl Lead" by Dr. Carozzi. I am going to Germany this weekend, to appoint two medical consultants. As you probably know, Herr Morgenthaler is now the Company^ representative in Germany, and has an office in Hamburg. I will let you know what transpires on my return. I have at last made a little progress in the South American field, and hope to visit that country early in 1950 I understood from Dr. Machle that you had some reservations regarding South America, and I would be most grateful if you would give me your instructions or comments on this territory. I understand that it is most unlikely that any manufacturing will be done in the Argentine, but the number of blending points is progressively increasing. I have heard, but cannot confirm it, that the frequency of blending and the amount of "ethyl" fluid used per gallon is ii cne or two places in excess of that permitted in our regulations. K 0010095 (Contd.) * i o * Dr. R.A. Keho. d a t e .....2cth July, 1949 - 2- There are two other medical officers with us now, Drs. N. Graham and M.D. Kipling. We are reserving next August for your visit, and looking forward to seeing Mrs. Kehoe and yourself. With kindest personal regards, Yours very sincerely, Ends. 0010096 I
