Copy letter from Robert William Frederick Harrison, to W Sparrow, 16 Pevensey Road, Eastbourne 'Dear Sir, I beg to acknowledge the receipt of your note and the box of lantern slides. I do not suppose the [Royal] Society would wish to permanently retain your photographs, as it has no collections of scientific objects; but if you can spare them for a few days I should like to show them to some of the Officers who might be interested to see them. I am, faithfully yours, Robt [Robert] Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 3 May 1904
