The rate of utili zation of ampules has very much stepped up and what reports we have received back suggest that the efficacy in lead poisoning at least appears good.

However, they have very little to do with the dangers of tetraethyl lead or Ethyl Gasoline, but are quite interesting with the gener al problem of lead poisoning* I hope to be able to re port soon on our experimental work on tribromanallne.

With reference to your recent article in the B.M.J. 0n Tetraethyl lead poisoning I think this patient is your number 3 and 1 thought you would like to know about. him for contrary to your general experience of these patients he does not seem to have made a complete recovery.

DISCUSSION GROUP on. the REDUCTION OF ENVIRONMENTAL EXPOSURE TO LEAD POISONING Meeting of 26 May 1969 The Rockefeller University The following individuals have indicated their intention to attend: LANKAN* Jonathan T., M.D.

The tank is leaking and we wondered if it would be safe to use as a water tank or for grain storage on account of the lead being poison* If so could it be treated to neutralize the lead?

Director, Environmental Health Lead Industries .Institute 292 Madison Avenue New York, New York 10017 Dear Jerry: Just a note to inquire about the progress oh publishing the proceedings from our two Regional Lead Poisoning Conferences earlier this summer.

The reference bo lead poisoning has been traced to the diagnosis of a doctor in Selma, Alabama,and should this individual care to stress the handling of lead gasolines,'there may be some reason for us to follow the matter further and report our findings to Dr.

I have studied a copy of your letter to Dr. de Priester and fully understand your views on the question of his desire to undertake routine lead analyses.

In the same general connection I would ~ also like to have the reference to the Australian work 1 which followed up the alleged connection^between chronic I nephritis and lead poisoning and which indicated that the : nephritis was due to scarlet fever. / I thoroughly enjoyed the discussion v; ef had last week on lead and am already looking forward to our next meeting
