THE UNIVERSITY OF CHICAGO CHICAGO 37+ ILLINOIS DEPARTMENT OF MEDICINE May 28, 1957 Dear Joshua: I showed your letter of the sixteenth and my reply to Dr. Cannon. He suggested that the best person to advise you was Dr. Dryden, the Home Secretary of the Academy. His only other comments were about the same as mine, that since it was the Botanists who got you into the Academy, they might well be offended if you joined another section at this time. Later on, if you should decide you wanted to shift to another one, you could do so. Sincerely yours, ’ be. C. Phillap Miller, M. D.
