Copy letter from an unknown correspondent; to [George Walker] Walker Esquire, FRS; 27 Anglesey Crescent, Alverstoke, Hants Is sorry to hear that Mr. [George Walker] Walker does not feel the diagrams appear big enough in his paper. Notes that he ensured it was passed for publication in the 'Philosophical Transactions' specifically so that the plates would be printed on a large scale. Further notes that, as the blocks have already been prepared, in the interest of economy they must leave them in their present form. 30 June 1921
