TJP CHILDREN'S HOSPITAL RESEARCH POUNDA'C^ Cincinnati 29, Ohio !' / Eilaad Ave. and Bethesda M+ . June 1, 1955 Mr. Manfred Bowditch Lead Industries Association l;2Q Lexington Avenue New York 17, II. Y. Lear Mr. Bowditchj I was most interested to receive your letter and enclosures concerning the Cninese baby that Hr. Byers and Dr. kalopf studied. From the data as given I do not find sufficient evidence to be absolutely sure of the diagnosis of lead poisoning. However, this does not prevent one from searching for possible sources of lead. The two main sources, of course, would be assimilation of lead either through the respiratory tract or the intestinal tract. It is hard for me to believe that the baby could get suggifient lead from the mother's milk without the mother having marked evidence of lead absorption. Therefore I feel that one ought to look more towards a common source of exposure, in particular a respiratory exposure. However, the data as given do not give me any clue and I am sure that Dr. Maloof has made an extensive search in this direction. Therefore X am afraid that I cannot really help out in this case.
