Copy letter from Robert William Frederick Harrison to The Lord Rayleigh OM, FRS 'My Lord, I have this morning received a note from the President suggesting that you have an impression that the reception of the Royal Society's Address fixed for to-morrow, may be postponed; but no notice of such alteration has reached here. On the contrary, a letter have just come from the Lord Chamberlain's office telling us that our Deputation must be at Marlborough House by 11.30 to-morrow and sending cards for every member; so I am directed to request members of the Deputation to assemble here at 11 o'clock so as to go down all together.' 8 June 1910
