March 5* 1965 Professor Harry V. Warren Department of Geology The University of British Columbia Vancouver 8, Canada Dear Professor Warren: 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 do 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 lone some work on polonium, but not in the relationship with which you are concerned. Cordially yours, RAK:meh Robert A. Kehoe, II.D. B 00527
