I have only one other comment to make, and that refers to the use of dye in this tetraethyl lead.

Lewi* Attached hereto ia exchange of correspondence with Lel&nd Doan of Doe Ghmieal in connection with the use of one hundred pounds of tetraethyl lead which we recently sen* them* I believe Mr.

It seems that wo have no official responsibility but In view of the association of the Bow Company with the Ethyl Gasoline Corporation, and In view of the significance of any manufacturing difficulties, which may involve tetraethyl lead, 1 think we should examine into this and sanction either the recommendations made by Colvin, or make such modifications in them as seem to be indicated by the cIreumstances I am sending Mr, Lewis a copy of this letter and X suggest that both you and he let me have your suggestions as to how host I can take up this matter directly with the Dow people* I realize that sometimes the people within an organisation ere a little sensitive and It would be well, therefore, to deal directly with the right person* Either Dr, Bachle or X will look Into thia*and we may wish some further advice in connection with the equipment which Is being employed by Dow* Very truly yours.

As to the knotty problems that you are coming upon in connection with tetraethyl lead and etyhl gasoline, I will be glad to discuss them with you at any time that is mutually agreeable.

Just reaching the audience at the California Club meting alone was a considerable step forward in the Job of keeping the industry safe from the 3jread of inaccurate information on the use of tetraethyl lead.

I have just received a letter from John in which he states that the present tetraethyl lead by gravimetric analysis ran as high as 2B% (Zd% fluid).

Lewis : I dare say the reason you do not have in your files corres pondence on the subject of the ordering of Ethyl Fluid and tetraethyl lead outside of laboratories, is that this was apparently a three-ring session between Kaley, Calingaert and, myself.

What he has done, however, is to influence the thinking of legislative leaders and medical people who up until now apparently have been confused about tetraethyl lead and lead oxide since much of their information seems to come from Mr.

of tetraethyl lead per American gallon and in connection with the operations concerned with the maintenance, fueling, repairing and overhauling of aircraft engines and fuel tanks.

Tetraethyl lead is an important example of this type of compound.

, e, absorption - of lead cannot possibly occur without elevation of the lead concentration in the blood except when the material absorbed is tetraethyl lead; the equilibrium with the blood is as inevitable as is the presence of inorganic lead in the body (you hardly need worry about tetraethyl lead, since this type of poisoning is almost never seen by physicians generally); 001249b Dr.

Van Hartesveldt of Thompson Products Company I told him of the results obtained in your Laboratory, both on the matter of the evaporation and selective absorption of tetraethyl lead by suspended material.

They see clearly that BAL does not save the lives of ani dose of tetraethyl lead, whether the latter is after the intoxication has developed.
