Copy letter from Robert William Frederick Harrison, to Professor John Henry Poynting, Fellow of the Royal Society Harrison is much obliged for Poynting's note and it Mr [Richard Tetley] Glazebrook has Poynting's report on Townsend's paper, it is alright, but as Harrison is responsible for these documents, it is important that he should know there whereabouts at any moment. It was a pure slip calling the paper McClelland's. [24] July 1896
