Copy letter from Robert William Frederick Harrison, to Professor John Theodore Cash, Fellow of the Royal Society With reference to Cash's card of a week ago, no photographer is making any authorized group of the Royal Society, and as some of the Fellows have already complained to Harrison of circulars they have received from a firm of photographers, Harrison wold be obliged if Cash would let him see the circular he was sent. Maull and Fox are making for their own purposes what they call a collection of Fellows and copies of these have been preserved by the Society as a matter of interest. 12 January 1900
