Copy letter from Robert William Frederick Harrison, to William Matthew Flinders Petrie, [Fellow of the Royal Society], 8 Well Road, Hampstead, N.W. The Soiree Exhibits Committee would like an exhibit from Petrie for the forthcoming Ladies' Soiree. Harrison has also been directed to request if Petrie would be willing to give a short lecture, or demonstration, perhaps with lantern slides, in the meeting room. This will not take up more than twenty minutes to half an hour, and would be most welcome. 2 June 1902
