co Dr. G Edgar Et hyl Gaso l ine Co r po r at io n Chemic al Re sear c h Labo r at o r y 1600 We st Eig ht Mil e Road Det r oit , Michigan June 4, 1941 Dr, Willard Machle Kettering Laboratory of Applied Physiology Eden Avenue University of Cincinnati Cincinnati, Ohio Dear Bills With reference to your letter of March 27, my "Department: for the Verification of Quantitative Statements" advises me that at a 20:1 air-fuel ratio by weight, 1 cc, of gasoline will require about 12 liters of air. Unless, therefore, you were figuring on a 10jl excess of air over that needed for combustion, your first statement should apparently read 11 liters instead of 110 liters. On that basis the tentative specification of 0,06 cc, TEL/gal. as permissible at the burner would be on the assumption that the com bustion products are diluted 10:1, I ivill thank you to confirm or correct the above statement. We are in any case, going ahead with our experimental work on that basis, and the data will be submitted to you for comments before we contact any outside agencies, such as the Army, Very, sincerely yours.

We -will work for the time being, on your safest figure of 0.06 cc. TEL per gallon. The method we are studying now, and which shows great promise, is the removal of the lead from the liquid gasoline at room temperature, by filtering through a bed of activated clay. In this case, there would be no question of thermal decomposition and filtration of the lead. C:C
