Copy letter from Herbert Rix, to Professor Ramsay, Fellow of the Royal Society 'Dear Sir, Lord Rayleigh desires me to write & say that he regrets that it is now too late for your paper to be taken next Thursday, as we have advertised as much as we shall get through, & on Thursday week the Croonian Lecture will be delivered, so that March 5th is the earliest date possible. If found practicable it will be taken that day. Yours truly Herbert Rix Asst Sec [Assistant Secretary]'. 17 February 1891
