Harris 12/14/67 RESTRICTED INFORMATION By phone contact on December 13, Dr. Cralley advi:1ed 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 totnlly different situatic'ns. Substantial dosages ever 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 ~ere forwarded. Although Dr. Cralley does not know L. J. McCabe personally, he will contact him and advise him of the current asbes'tos industry study and our relationship with the Department. H. M. Jackson P.
