Mr. S. French Reeves, John !. Lewis and Brothers Company, Widener Building, Philadelphia, Pennsylvania.
Dear Mr . Reeves :
In Dr. Kehoe*s absence, I am submitting below the analytical report on the blood and urine samples obtained from*
Urine 0 .u9 milligrams lead per liter; blood 0 .065 milligrams
lead per hundred grams.
Both these figures are well within the limits found In safe
occupational exposures.
'
In view of the significant history of severe lead exposure in the p a s t , they are particularly informative as indicating adequate deleading procedures, and there is no reason to be concerned about undue lead absorption or retention in this case on the basis of these analytical results.
Very truly yours,
KVK ef Enc.
