Letter from [John Stanley] Plaskett, Director of the Department of Interior, Dominion Astrophysical Observatory, Victoria, to the Assistant Secretary of the Royal Society, Burlington House, Piccadilly, London, England 'Dear Sir:- I enclose my annual contribution of £5 due next month. I propose to come to London in June to complete the requirements of the Society which the Council graciously allowed me to postpone and I note there are ordinary meetings on June 11, 18, 25. I would prefer of course to attend when the meeting deals with the physical rather than the natural sciences and I would hence be obliged if you would advise me which of these dates would be most suitable for me to be formally admitted. Yours very truly, J.S.Plaskett'. Enclosed is a reply from the Assistant Secretary of the Royal Society to Dr J S Plaskett, dated 13 March 1925. 21 February 1925
