N, Gotham at San Antonio, Texas, concern ing a presumed case of tetraethyl lead poisoning in "an employe of the government who handles lead tetra ethyl in on of the ware houses at Duncan Field".

So far as we are able to d etermine, this is true only of organic lead compounds, such as tetraethyl lead.

As to the similarity of lead chloride to lead tetraethyl, you need have no anxiety.

The higher volatility of tetramet to increse the hazard, with particular refe of gasoline, but this is counter-balanced t lower toxicity vis-a-vis tetraethyl lead an overall increase is of little or no practica Since the overall problem does no from that presented by tetraethyl lead, the recommendations will be applied in respect distribution as apply to tetraethyl lead at K ooo824c; would be desirable to inform the appropr authorities in Australia of the possibil containing T.M.L. may be introduced into acquaint them with the nature of the hyg its present status in the U.S.A.

I .- '' 1 am also sending you a brief resume of the preliminary toxicologic observations which we made years ago on tetramethyl lead, tetraethyl lead, and the mixed alkyls in between them.

The symptoms of illness which have been described in connection with this man are by no means specific, and a diagnosis of early tetraethyl lead poisoning must needs be made only after the most careful consideration.

Th<p symptoms of illness which have been described in connection with this man are by no means specific, and a diagnosis of early tetraethyl lead poisoning must needs be made only after the most careful consideration.

For your information, I may point out that our observa tions during the war demonstrated clearly that chronic lead poisoning of the classical type is not to be ex- pexstaasked *as the result of exposure to tetraethyl lead.

aecond, clinical findings and the reputed character of the illness do not suggest tetraethyl lead poisoning.
