Letter from Simon Flexner, the Rockerfeller Insitute for Medical Research, 66th Street and Avenue A, New York, to Professor Arthur Schuster, Secretary of the Royal Society 'I am back to-day from the woods of New Hampshire, from where I wrote you a week or so ago. I find on my desk the "diploma" of the Royal Society which had not been forwarded, and I make out that the election was to Foreign Membership and not Fellowship, as I had been informed. I trust that my acknowledgement will serve for this honor, which is of course equally great and deeply appreciated.' 9 September 1919
