I ,February 27 1967 Dr, M. J. Thomas Research Division Building Do. 33 national Cash Itegistcr Dayton 9, Ohio ' . Dear Dr. Thomas: ' Attached is a photostat of the original paper of Dx*. Jenson in Sweden, relating to polychlorinated biphenyls. I will be happy to have your ideas after you road it, As far as the section on toxicology is concerned, it is true that chloracno and liver trouble can result from large doses, V/hothor or not this is at all relevant to cnall qua**titles existing in human fat is, of course, an entirely different question. At any rate, I believe before wo worry about the toxicological part of the problem, we should settle the analytical part. . Sincerely, RKK/ln att, R.
