It will take some days to do this and I am doubtful if I shall be able to do so before the end of text week* Perhaps we igay save time if I raise the question now as to whether you will authorize a few days of hospitalization for Mr, Gast if it becomes necessary through the failure of these present tests to settle the question at issue* I have had reason from time to time to sus pact that certain local physicians are not above the administration of significant dosages of lead in order to produce laboratory findings compatible with the diagnosis of lead intoxication.

Hackett, the director of the Industrial Health Bulletin, offering certain criticisms which were directed more at the am biguity of an article on tetraethyl lead than on any actual incorrectness of the facts.

The quan tities of arsenicals annually used in the United States for this purpose was estimated by Sturmer to have amounted to 80,000,000 pounds (mainly lead arsenate).

I am not in position, however, to make an arbitrary decision in which I would say with certainty that lead had nothing to do with his Illness.

In general it may be said that the quantities of lead involved here are so small, while the quantities of gasoline are so relatively large, that one would not expect to see injury from the lead.

You sent me before a copy of the pamphlet on the "Normal Absorption and Excretion of Lead", so X am return ing one of the copies herewith.

The General Ledger account "Discounts Allowed" is cleared each month to the White Lead and Zinc Oxide Departments of the International Smelting and Refining Company.

I note that you have an opinion that the ingestion of lead at least over a long period of.time in quantities greater than!'.

I volunteered-to do thi3 analytical work because X was intereste& in seeing that you got off to a good start, but also because I was very much interested in connection with our experimental studies, in obtaihing data on the lead Intake and output of French Workmen, Having obtained these samples before the actual work in the tetraethyl lead plant had begun, we were enabled to learn something of these facts without the of the factor of occupational lead exposure.

kith tanks that have not been used for leaded gasoline, the above precauti on clothing will not be followed.

It was feared early in the history of the commerce, that the slow minute absorption of lead o\it of gasoline over I a long period of time,might eventually produce cases of chronic lead poisoning.

Corporation, have been Investigating all claims of Injury in connection with the normal handling of leaded gasoline* In as much as this claim arises from the in gestion of leaded gasoline with drinking water, it does not belong in the category of injuries associated with the commercial handling and normal use of gasoline.
