Dr. William R. DeCesare was kind enough to mention that he had heard your address at the AFCR and that it might be useful to me in rounding out my perspective on the activities of clinical. investigators. This would be most helpful for our strategic planning for the Rockefeller University Hospital. If it is not too much trouble may I ask the courtesy of seeing a draft of the paper that he referred to? I would, of course, also be interested in any other publi- cations or observations that you may have pertinent to this general theme. XN Yours dincerely,) Jostiua Lederberg
