Copy letter from Robert William Frederick Harrison to Dr C [Charles] Chree FRS 'Dear Dr Chree, A meeting of the Sectional Committee for Physics and Chemistry has been summoned for Wednesday, the 6th, and it would be a great convenience if we could have by that date your report on Mr Southern's paper. If, however, you are unable to report by then, perhaps you would be good enough to return the MS [manuscript] for use at the meeting.' 4 July 1910
