Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to Professor John Stanley Gardiner FRS, Chairman of the Zoology Committee 'Paper by MacBride and Jackson on "The inheritance of colour in the stick insect". Prof Bateson reports in favour of publication and makes suggestions with regard to reproduction of plates. A copy of report is enclosed. We can, I suppose, obtain an estimate from Trap of Leyden if the firm still exists, but I should imagine there would be considerable delay, owing to the war, in getting work done in Holland.' [no enclosure] 9 June 1915
