March p> 1965 Professor Harry V. Warren Department of Geology The University of British Columbia Vancouver 8, Canada Dear Professor Warrens Please accept my sincere thanks for your letter of March 1. I shall be delighted to see the results of your observations on soils and vegetables. I cannot promise to comment extensively on them or with any great degree of prompt ness, since I am even more hard pressed than usual (in an attempt to get the decks cleared, so far as may be possible, ' by the time of my retirement in July). I <3?o wish to see them, / however, and I'll hope to be able to make some response. , I must answer your final question in the negative. My successor, Edward P. Radford, has done some work on polonium, but not in the relationship with which you are concerned. - ' Cordially yours. RAKsmeh Robert A. Kahoe, M.D. 1 00527
