Ju ly 28* 1937 Hr* I * Dent Jenkins Harrison Radiator Division General Motors Corporation Lockport* Hen York Dear Mr* Jen kin sj I did not reply at ones to your le t t e r of Ju ly 20th because I was In the process of preparing a report which would cover a ll of the de t a i l s except the fin a l an aly t ical r e su lt s* The an alysts on the blood samples and on the spot urin e samples which I collected at the time of my v i s i t , are fin ish ed and I have a l l of the other data tabu lated except for the an alyses on the large samples* X expect to fin ish my ropcr-fc up to th at poJn t within the next day or two, and I w ill send i t along to you promptly. I t may he of some in t e r e st to you to have the in dividual records of my examinations at once, and I am sending those herewith* I have not made comments on the in dividu al examination records sin ce the data on th ese w ill be self-explan atory to Dr. Hlllenbrand* The fin a l an alyses w ill probably not be completed before I get away on my vacation * I f they ar e, I w ill send them along to you with such ad d it ion al oesaments as may be ^Justified* I f they are not completed before I get away, I w ill have them sent to me fo r exami n ation and w ill make any addition s to my report which they r equ ire. I have a hunch th at they w ill turn out to have su b st an t ially the same sign ifican ce th at th e small samples of urine and th e samples of blood h ave. You are quite r igh t in believin g th at the r e su lt s which I have obtain ed are favor able* Xf I had found any evidence of ser iou s danger, I would have reported I t to you promptly* As i t i s , I have seen no evidenc in any of the data th at th ere are r eally seriou s h azards in your plan t* My report w ill make i t clear to you th at X do not regard the evidence as en tir ely adequate but such as i t i s , i t fa l l s to In dicate the l ik e l i hood of any seriou s d iffic u lt ie s. There is on man in the group, nemely Mr* Sco t t , who h as a conhination of fin din gs which are ` suggestive of sign ifican t lead exposure* I think we should KB GO. 4O ^ . -j * wait u n t il the an alyses of. h is other samples to ar r ive at any d efin it e con clusion * but I believe t h is is the only man about whom there may he any sign ifican t question# In order to be sp e c ific * I c a ll your atten tion t o the fact t h at t h is man had a sligh t darkening of th e gums somewhat suggestive of a load lin e * He had a sligh t ly low blood pressu re* somewhat In creased r e fle xe s* some involvement of the w r ist s* some tremor* a sligh t anemia, a l i t t l e st ip p lin g above the average normal le v e l* and a lead con cen tration in th e spot sample of urine of 0*17 mgs* per lit e r # (The average normal In dividual does not show a con cen tration in excess of 0*5.0 at the h igh est#) I doubt i f any of t h e t -1*.f X have in dicated as abnormal in t h is man could properly be at t r ib u t ed to h is lead ab sorption , except th e r e lat iv e ly high lead excretion In the urin e* I sh all have more to say about him la t e r when I have seen the fin a l an alyses. However* i t is worth while to c a ll your atten tion to the fa c t th at the development of any more sign ifican t illn e ss in t h is man could very w ell be regarded as lead in toxicat ion * At le a st i t would be vary hard to d isp r o v e * I have not forgotten th at you loaned me a book when I was in Lock port* I have not en t ir ely fin ish ed reading i t but I am taking good care of i t and you can be sure I w ill return i t * Cordially yours, HA'Kss Robert A# Kehoe* M.B
