E. & W . , Cincinnati, Ohio Note to: C. B. Burnett G. W. Wright, M.D. E. M. Fenner A. C. Smith D. L. Hinmon F. J. Solon W. P. Raines M. Harris ' . 12/14/67 ` RESTRICTED INFORMATION ' . ' By phone contact on December 13, Dr. Cralley advised me that he was aware of the Nashville situation-- in fact, had been asked to make comments for Dr. Murray Brown's use and signature. He indicated the essence of the comments were that the asbestos health hazard potential via the routes of inhalation and ingestion were two totally different situations. Substantial dosages over long periods of time were necessary to produce ill effects by inhalation. In his opinion, it was inconceivable that sufficient fibre intake could be accomplished through the ingestion route alone, and particularly so when related to the water intake capacity , of humans. He also expressed an opinion that a pH which would attack the cement would also attack and modify the fibre. Dr. Cralley does not know whether the comments were forwarded. Although Dr. Cralley does not know L. J. McCabe personally, he will contact him and advise him of the current asbestos industry study and our relationship with the Department. H. M. Jackson P. S. - Copy of L. J. McCabe's letter of December 7, 3.967, is attached. . RESTRICTED INFORMATION PRODUCED JM - 83
