Copy letter from Robert William Frederick Harrison, to Lord Rayleigh [John William Strutt], President, Royal Society 'Notice to Fellows re Soiree Exhibits Will the President kindly say if he approves of the enclosed notice being sent round to the Fellows? Some notice must be given them if they are to gain the benefit of the afternoon demonstration, and I have referred to the other exhibits so as not to make the notice too special to Brennan. RWFH'. 12 June 1907
