Dear Doctor Siegel:
I send you herewith two copies of the analytical results on your men, and a hill to cover the cost of the analyses.
The lead concentration in the blood of individual men is slightly elevated above the mean of normal values, but in no instance is there evidence of dangerous lead absorption. Only one man's sample of urine ;.iad an unusual concentration, and only two were above upper normal levels . No evidence of dangerous lead enposur is provided by these data.
If there should be any questions about the results in any of these men, do net hesitate to let me have them.
Very truly.yours,
EAEC ef Enc.
