Copy letter from Arthur William Rucker, to Gilbert Thomas Walker, John Alexander McClelland and Charles Thomas Rees Wilson 'We have rather a long list of papers for April 8th, and I write to ask whether you would prefer that your paper should be put down for that date, or postponed till after Easter. If you would rather wait, the paper can probably be taken on May 13. I am, Yours truly, Arthur W. Rucker Sec. R. S. [Secretary, Royal Society]'. 26 March 1897
