Copy letter from Herbert Rix, to Professor Joseph John Thomson, Fellow of the Royal Society 'Dear Sir, May I venture to make known to you that we have had inquiries for your "Notes on Recent Researches on Electricity and Magnetism", a volume which this Library unfortunately does not possess. As most of our Fellows have been good enough to send us copies of their works, I trust that you will not take it amiss if I suggest that a spare copy of the same might perhaps be found for the Library of the Royal Society. I am, yours faithfully, H. RIX Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 31 July 1894
