Copy letter from Herbert Rix, to Professor Johnston-Lavis, 40 Ebury Street, S.W. 'Dear Sir, I am sorry to say that your application for an invitation to our Soirée comes too late, as the Soirée Committee have already held their last meeting, and I cannot get permission to issue additional cards. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 7 June 1894
