Copy letter from Robert William Frederick Harrison, to Messrs Lafayette Limited The President of the Royal Society [Sir Archibald Geikie] has been consulted on the subject of obtaining a group photograph of the delegates to the Royal Society's 250th Anniversary. It is feared the idea of a group photo in the quadrangle of Burlington House is quite impracticable for various reasons. If a photograph of the ceremony of presenting Addresses in the large Library is practicable, without posing specially for it, there is no objection to that. Their suggestion of a group photograph at the Duke of Northumberland's garden party at Syon House, must be decided by the Duke. 10 July 1912
