w; * t Dr*;Bonnard Teegarden #1 Bast Ninth Street New York, New York . - My dear Doctor Teegarden: ' '< ' ' I am sending you herewith the results obtained on the samples of blood and urine of Mr. f l f l i H M P ^ h e s e results are well within the normal limits. They compare very well with results obtained consistently on young healthy experimental subjects selected on the basis of a completely negative history with respect to lead exposure.jin as much as the blood and urinary findings are mutually confirmatory in that both are entirely normal I see no reason for making any further observations. - I should be interested in knowing how these results compare v/ith those obtained else where, and.also how long ago the initial result of 0.11 mg* per liter, which you cited, was obtained.,; In any case, these results in my opinion exclude any possibility that this man is suffering from active toxic symptoms due to lead at this time. I shall be very much interested to hear of any further clinical developments in this case. . , . . With my thanks for your courtesy. - Cordially yours, RAKivn cc Mr. Lewis Robert A. Kehoe, M. D. oon
