July 11, 1989 Mr. Alden J. Pahnke Assistant Director E. Z. du Pont de Nemours b Co. Petroleua Laboratory Wilmington, Delaware 19898 Dear Mr. Pahnke: I bad a few extra copies of the paper which I gave (in part) at the A.P.C.A. meeting in New York, struck off, for people who had reason to be especially interested in the subject under discussion. I enclose such a copy for you. If, for any reason, you would like to have other copies made for people within the du Pont organisation, I gladly authorise you to do so. It may well be months before reprints of this article in its final fora (which differs in some respects from that of the preprints) become available. Very truly yours. J RAK:wp Robert A. Kehoe, M.D. Professor Emeritus of Occupational Medicine 0111 J
