Copy letter from Herbert Rix, to William Crookes, Fellow of the Royal Society 'Dear Sir, I believe you suggested that Mr Streeter might exhibit at our forthcoming Soirée. The Committee, however, purposely did not invite Mr Streeter this year as Tiffany & Co, New York, are making a jewellery exhibition. We shall be very glad to have Mr Streeter's aid on some future occasion. Meanwhile, you will know whether or not it is necessary to drop him a line upon the subject. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 12 June 1891
