Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society; to Sir Joseph [John] Thomson, President of the Royal Society Refers to the Council's desire to host a Soiree at the Society. Suggests that the first step ought to be summoning a meeting of the Soiree Committee to outline the scope of the event and draw up a list of invitations. Notes that at present no Soiree Committee exists and asks if Sir Joseph [John] Thomson could nominate one for this purpose. 24 March 1919
