The dilution of tetraethyl lead with gasoline also largely eliminates the danger of lead inhalation.

I do not regard the warning on your yellow label as entirely adequate since in general chemists will have the point of view that the vapor pressure of tetraethyl lead at ordinary temperatures is so low as to be essentially negligible.

In the matter of your statement as regards intra ethyl lead poisoning, my objection was not that reference was made to tetraethyl lead which produces a type of poisoning in large doses more serious perhaps than any other lead compound* The misleading portion of the statement consisted of the fact that reference was made to the seriousness of the poisoning asso ciated with anti-knock gasoline containing tetraethyl lead, whereas all of the evidence indicates that lead poisoning from this;1type of distribution of tetraethyl lead is non-existent.

The lead content of the fluid was found to be 8.43$ which would corres pond to a tetraethyl lead content of 13.11%.

I# The history of exposure is not adequate* One cannot be certain that the patient was actually exposed to tetraethyl lead* It is assumed by the physicians, apparently, that the chief ex* posure to lead occurred through Inhalation* Inasmuch as the Ethyl Fluid in the pump was diluted with gasoline, one cannot be certain that actual Inhalation of tetraethyl lead occurred* It was pro bably slight and perhaps negligible, since apparently only fifteen minutes elapsed during the repair* The question!

lo case of acuto tetraethyl lead poisoning has been seen to persist with active symptoms or evidences of abnormal lead excretion through such a period. 5* The lead examinations reported by Dr.

'This has to do with the storage of tetraethyl lead in the Kodak Company's laboratory in bottles of 2-quart capacity.

The one concerns itself with demon strating that the alleged injury is not due to the effects pf the absorption of tetraethyl lead.

Machie, Dear Bill: Thanks very much for your letter of December 26 in connection to du Font's using tetraethyl lead for the manufacture of lignosan and ceresan.
