Copy letter from Herbert Rix, to George King, 12 Sunderland Terrace, Westbourne Park, W. 'Dear Sir, The corrections in your blocks can be made pretty easily, by means of plugs. The paper will have to appear in its chronological order, and will not, therefore, be out for two or three weeks. We never send revises in pages. Yours truly, Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 25 July 1893
