Et h y l Ga s o l in e Co r p o r a t io n Ch e mic a l Re s e a r c h La b o r a t o r y 1600SggJ We s t Eig h t Mil e Ro a d De t r o it , Mic h ig a n March 12, 1941 Dr. Willard Machle College of Medioine University of Cincinnati Cincinnati, Ohio Dear Bill: I understand from Dr. Edgar, that your data on the operation of the Army stove show 90% retention of lead on the filter, as compared with the 70% which we found. Off-hand, this may be due to insufficient heating in our case, or merely to inaccuracies in analysis. If the first is true, it would seem that some experiments would be in order, using higher cracking tube temperatures. Perhaps we should send you our stove to see whether you get better recovery, and if you don't, we could design and build for you a cracking tube that would destroy the TEL more thoroughly. I would appreciate your comments and will be glad to give you any assistance we can in running this down. Very sincerely yours. jig 0009506
