Committee on Lead Poisoning, and your prompt and helpful response thereto.

If, on the other hand, work with leaded gasoline along the lines first indicated have been resumed, you may have some interest in my comments.

We expect to obtain representative samples of material from the sides of the tanks and from the sludge at the bottom In order to assure ourselves in relation to the histories of use of these tanks an to what are the factors which give rise to decomposition of tetraethyl lead in the gasoline, and what quantities of lead are involved.

With the blower in n(t>rmal operation, take another four cubic foot sample and de termine the lead content of the air so sampled.

i The above is particularly true with reference to the specific sources of lead absorption.
