Last issue of the BULLETIN OF THE BELL MUSEUM OF PATHOBIOLOGY before Professor Day left Minneapolis for the Sloan Kettering Institute of Cancer Research in New York City. "A parting should be an occasion of few words. My returning to Minnesota in 1971 to join Robert A. Good was determined solely on his willingness and support that the Bell Museum of Pathobiology should be founded on an intellectual concept as a "Museum Without Walls", devoted to the proposition that a correct study of disease must encompass the WHOLE man, and that scholarly studies fostered within this unit of his department of pathology should encourage multidisciplinary perspectives with other branches of medicine, and importantly, perhaps even more importantly, encourage INTERDISCIPLINARY intercourse with our University colleagues in ALL OTHER BRANCHES of knowledge".
