whilst serving with the Royal Air Earce during World War II, I came down with chronic lead-poisoning.

Proposed Red lead Technical Letters.

If we look very hard at our cases of lead poisoning that are clinically serious, they have had big doses of lead and/or long exposures.

At the moment urinary lead estimations alone are done.

This tank has 94,000 barrels in capacity and according to our lead-in-air test, the highest lead reading obtained at any time was 15 mg. per cubic ft. of air.

Perhaps I can best state the background of my point of view by sending to you, as I am doing herewith, a report of an article which we published some time ago* This article will be followed shortly by a rather lengthy one which is the result of certain more detailed studies*, The results substantiate the conclusions which I originally arrived at to the effect that the hazards of exposure to leaded gasoline in the present concentrations are too m a l l and insignificant to be measured by even the very delicate methods which we have employed* I am of the opinion that leaded gasoline should not be used either for leaning various parts or for general use in cleaning motors* In the first place, there is no advantage gained by using leaded fuel for this purpose, and there is so far as I can see no point in permitting any question of risk by such means.

It seems to me that it would be impossible to insure that .. each leaded gasoline car that would be cleaned could be brought to the point where it would be considered lead-free and therefore safe for the transport Of edible oils.

Samples of earth taken from the rear yard of his home showed 0.2$ lead maximum.
