Copy letter from Robert William Frederick Harrison to Professor H [Hugh] L [Longbourne] Callendar FRS 'Do you think it necessary or desirable that there should be a meeting of the Physics & Chemistry Committee before you go out of office next week, and I should be glad if you would send me a telegram, naming a day. If not, we can arrange for a meeting early in January under the new Chairman, Prof Poynting.' 15 December 1911
