Letter from Ivan de Burgh Daly to John David Griffith Davies, Department of Physiology, University New Buildings, Teviot Place, Edinburgh 'Dear Griffith Davies, As I have to be in London on the 12th of June, I wonder if you could arrange a sleeper for me from Edinburgh on the night of the 11th instead of the 12th. There is no alteration in the time of my return journey and I shall still want the sleeper from London to Edinburgh on the night of the 13th Yours sincerely, I. de Burh Daly'. ' 4 June 1946
