UNIVERSITY OF LONDON KING'S COLLEGE. From The Wheatstone Professor of Physics, J. T. RANDALL, F.R.S. STRAND, W.C. 2. TEMPLE BAR 5653. Miss R.E. Franklin, Birkbeck College Research Laboratory, 21 Torrington Square, London, W.C.1 17th April 1953 Dear Miss Franklin, You will no doubt remember that when we discussed the question of your leaving my laboratory you agreed that it would be better for you to cease to work on *he nucleic acid problem and tclbe up something else. I appreciate that it is diffioult to stop thinking immediately about a subjeat on which you have been so deeply engaged, but I ahould be grateful if you could now clear up, or write up, the work to the appropriate stage. A very real point about which I am a little troubled is that it is obviously not right that Gosling should be super- vised ky someone not specifically resident in this laboratory. You will realise that the necessary reorganisation for this purpose which arises from your departure oannot really proceed while you remain, in an intellectual sense, a member of the laboratory. Yours sincerely,
