(19) Juno 2 3 , 1943 Mr. 0. B. Levis, E.hyl Corporation, Chrysler Building, Rev York City 17 Attentions Mr. E. 0. Jones Dear Mr. Jones This is to acknovledge the receipt of your letter of June 15, vith the attached correspondence vith Sergeant Oscar P. Coheir; I have received a letter from Sergeant Cohen, asking for infor mation about tetraethyl lead, and I have sent him all of the infoiraation ve have. I also urged him to come to visit us and suggested as tactfully as X could that I consider any additional toxicologic vork somewhat unnecessary. For a number of reasons I thought it vas worth while to try to discourage additional experimental vork, and although I may not succeed, it seemed worth a trial. I shall pass on to you any additional information that comes to me. Cordially yours, RAK ef Sotert 'ieiioe>"M "e>t'
