Jims 7, wm Captain E* L Bergquist, Station Hosptial, Air Corps Advanced Plying 'chool, Kelly Field,: Texas * Dear Captain Bergquistj I have your letter of* June 3rd and will endeavor `to answer your questions to the best of jay ability, 1* ETHYL riilTD contains tetradthyl lead and aa organic iialxd (In the avaition fluid the halid is tftyXensdihroisid, and the proportion of tetraethyl lead to othylsn^-ai-troaid is that theoretically required for complete combination to fora lead brtffldd), la the ocaabustioa* it is boliaved that the tetraethyl lead burns to load oxide and the halids to acid, these tssr then, ccaabining to farm, lead ha34d*, This material is largely volatil ized opt of the cylinder itself and is partially deposited In the exhaust system and partially blows out with the exhaust gases - 2e There is no evidence that there .is any material difference in th chemical reactions in th fuel between axttoasobila motors and air play motors# 3* Tetraethyl lead is oxtremsly easily oxidised and 1 do not believe that there Is ary possibility 'that uritnsrned tetraethyl lead con a arm out of th cylinders* 4* The experimental dote mina^iaa of the quantity of lead in exhaust gases ds^xiremely difficult since, at least* a part of .the load Is tton^very finely divided solid state which permits it to pass through most scrubbing systems.

It will be , '*' v observed that the absolute values for TEL cover a wide range as does the ratio of lead from TML to lead from TEL.
