Copy letter from John David Griffith Davies, to Sir Henry Thomas Tizard, Magdalen College, Oxford 'Sir Henry, I enclose a copy of a letter which has come to you from Hans Pettersson. It was really addressed to you as Foreign Secretary so I am passing the original on to Professor Hill. I thought, however, that you might like to know what Pettersson said in reply to your letter. Yours sincerely, [John David Griffith Davies] Assistant Secretary'. 19 December 1945
