Copy letter from Robert William Frederick Harrison, to Professor Joseph Larmor, Secretary, Royal Society Omitted to say in his note last night that they had to modify the idea of putting Righi near Silvanus Thompson because of a letter from Ayrton saying Righi and his son were coming to stay with him. An invitation has been sent for the son, who will come with Ayrton. A portfolio of Mr McClean's photographs of Stella Spectra has come from Standford's addressed to Larmor. Asks if this should be sent to Cambridge. 29 November 1905
