Copy letter from Robert William Frederick Harrison to Dr C [Charles] Chree FRS 'I understand at yesterday's meeting of the Physics and Chemistry Committee that you wished to withdraw the paper by Mr R B Sangster recently communicated by you. If this be to, will you be good enough to send me a intimation - required by Standing Orders that the paper is to be considered as not having been communicated to the Society at all? And the paper is being returned at once.' 5 May 1911
