(19) June 23, 1943 Mr* 0*6* Levis# E.hyl Corporation# Chrysler Building# Rev York City 17* Attention: Mr. E. 0. Jones Dear Mr. Jones: This is to acknowledge the receipt of your letter of June 15, with 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 was 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, i 3 IRAK ef SoSert & * ' iehoe # "MI "t> *
