Tisdale Imperial Oil Limited ' Winnipeg, Manitoba, Canada Dear Doctor Tisdale: I have a copy of a letter written to you by my secretary, Rahe, on June 18, written at my request and stating that the of lead analyses on samples of ur ineandblood on the seoue and were incon- now enclosing the actual results of these analyses ta on the urine and blood of a n e t were reported at a later date. The r e s u l T s on Mi*, ere also no t s i g n i f i c a n t and w o u l d indicate that the had been no recent occupational exposure of any significance. T-f- sc;orrs to me that I d id Irnov/ at one me-f- -* the sp e c i f i c reason 'or these samples being s u b m i t t e d but I have not boon able to iad any notation of that reason, nor can I remember specii'i c a l l y wha t trie r e a s o n was. V.'e v.ouId like to k n o w for our records if those samples arc submitted only as a routine check on the men who have some possibility of lead absorption or whether there was for some reason or other a knowledge of some possibility of an actual exposure. Yfe are very g l a d to run the samples in any event, but are always interested in the specific reason for the analyses. Very truly yours LWS:vr Enel. - 2 cc - Dr. R. A. K e h o e L e s t e r W.
