December 9, 19^1 Dr. Willard Machle University of Cincinnati Cincinnati, Ohio Dear Bill: I have sent, under separate cover, your pipe. It should arrive shortly. It was parked by the cock tail shaker. I am also forwarding, under separate cover, the papers you left here together with a list of the men In our regular excretion group showing the length of ser vice in the Tetra Ethyl Lead area. You will note on sev eral that there are a series of dates. These dates indi cate the periods of time scent in the Lead area. We are also giving you a memorandum on the productlon from 1926 to date. This is expressed in millions of pounds. In other words, .7 represents J00,000 pounds.. Note there is a correlation between production and the symptom8 we have seen on the charts we examined. While this is not entirely accurate it is apparent that with the increase in production there has been an increase in symptomatology. Very truly yours, WILLIAM KIRK, MANAGER BY: E./E, Evans, M. D.
