Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to Professor Charles Herbert Lees FRS, Chairman of the Physics and Chemistry Committee 'Paper by Lt. Col. Hadock on "the longitudinal length of steel cylinders closed by screw plugs". Dr Chree reports again publication. He says, "The paper may be suitable for publication in some military or engineering journal, but seems too technical in its methods and mode of presentation for publication by the Royal Society. No justification is attempted for the great liberties taken with the mathematical theory of elasticity". Dr Chree's supplementary remarks are enclosed. Will the Chairman please say what further action should be taken with regard to the paper?' [no enclosure] 7 July 1915
