Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to Miss Florence Davidson, Farnborough, Kent Replies although there is no reference to Prof. John Milne having worked on the Ultra-Violet rays and glass around 1890, Miss Florence Davidson may be right. Asks for her Dusseldorf [Germany] correspondence to send in clearer references. Explains Milne was in Japan in that time working mostly on Earthquakes. 14 November 1928
