Copy letter from Herbert Rix, to L Pyke, 33 New Tothill Street, Westminster, S.W. 'Dear Mr Pyke, I am sorry to say your suggestion of exhibit came too late, as we are already more than full for the Soirée on May 2nd. I think it might be an interesting exhibit for the June Soirée, and shall lay it before the Soirée Committee when they meet to arrange for that night. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 27 April 1894
