Copy letter from Robert William Frederick Harrison, to Professor [William Henry] Bragg, Fellow of the Royal Society The sooner he sends his new paper the better. It is expected to have numbers of 'Proceedings [of the Royal Society]' out both for August and September and as Professor [Arthur] Schuster has given Harrison authority to accept the paper it ought to be able to get it out in the September number. August is already filled and gone to press. [This is addressed as W L Bragg FRS, but presumably Harrison means W H Bragg FRS]. 28 July 1913
