tal* 7, 1939 Dr, Henri Girolle S Hue Scribe Hantes (boire Inferieur) France Dear - Doctor. Slrolref**1 : I am sending you herewith two copies of our analytical results on the feces which you sent us some time ago* There has been some little delay in completing these analyses by reason of the fact that we have been working under a considerable pressure from other things* X hare only one practical suggestion to make In connection with these data* The sprinkling- of high results in excess of one half a milligram per sample is probably indicative of abnormal-lead exposure. They nay merely be ^ chance contacts with unusual quantities of lead on the day before the samples were taken. If that is the case* such- results would not be reported regularly in the case of any one individual. On the other hand there.is a chance that these results represent a certain amount of personal carelessness. It would be wise, therefore* to Investigate the behavior of those men who show these high results. This should be done quietly and discretely for the purpose of assuring ourselves as to the general mode . of behavior of the men in question. Consistently careless men are obviously a Source of disadvantage in this type of work and altbcu^i they may not provide any certain evidence of such carelessness, they do give one a clue which is worth some slight Inquiry, o I hope to be able to return CO your paper to you shortly. It has been necessary to submit it to the DuPont people in order that there may be no revelation of Information which in their minds should be held confidential* regards t I am With the most cordial Sincerely yours* Kf f 00003 RAKjls Robert A,1KHoe;""':
