Copy letter from Robert William Frederick Harrison to Sir J [Joseph] Norman Lockyer KCB, FRS 'Dear Sir Norman, Concerning the meeting of the Solar Commission at the end of this month, we have no meetings to interfere with the loan of a committee room on the 28th and 29th, but we have another candidate for a room on Wednesday, the 30th, although it is not yet promised. Could you let me know how many people will probably be attending the meetings of the Solar Commission, and whether it is really probably that they would run on to the Wednesday.' 9 June 1909
