This may or ma;,y not be true, since the usual case of lead intoxication Improves in varying degree of promptness, when exposure to lead is brought o an end.

The first report considers the total amount of lead.

Secondly, I recommend the use of E.D.T.A., not routinely and not prophylactically, but in those workers with high urinary lead values (with confirmed urinary lead values of 0.20 mgm/liter and over).

Stevens, Since last writing to you about the fatty salts of lead, further salts have now come to my notice, namely the following:- lead sterate, and lead adipate, in which I would be grateful for knowledge of the toxicity in terms of the metabolism and chemistry of the body.

The two points at which It seems to me trouble might well occur, have to do with possible volatility of tetraethyl lead in lubricating oil and the possibility of skin absorption of tetraethyl lead out of lubricating oil.
