Copy letter from Robert William Frederick Harrison, to Captain K E Edgeworth, Brompton Barracks, Chatham No paper can be received by the Royal Society unless it has been communicated by a Fellow. There is little doubt that the Physical Secretary Sir Joseph Larmor would take a look at it and, if he thought it suitable, communicate it, but it would be more in order if it came first through a Fellow. 26 January 1911
