There are three letters from David Lorimer to Sidney Duly and one letter from Emily Lorimer to Sidney Duly. There is a further letter from Duly to Richard Pankhurst, RAS Librarian, to donate the material to the Society

Letter from David Lockhart Robertson Lorimer to Sidney John Duly in which he apologises for his behaviour concerning oranges but all his time has been taken up with sorting the ARP and "Black-out". He therefore has been unable to touch his own work or photography since the middle of September. He feels the problem is spiritual and that he does not feel at home in a world of Hitlers and Chamberlains. Lorimer is returning Duly's "Latent Defect" and adds his comments on it. Written from Welwyn Garden City, Hertfordshire. Handwritten with embossed letterhead, 2 pieces, 3 sides, dated 11 November 1938.

This series consists of correspondence between the Lorimers and Sidney Duly, manuscripts concerning the Gilgit Expedition; and some printed articles by the Lorimers. There is also a letter from Duly to Richard Pankhurst, RAS LIbrarian, to donate the material to the Royal Asiatic Society.

The material consists of two folders. The first contains correspondence, manuscripts and printed material connected to the Lorimers' expedition to the Gilgit-Baltistan region, Pakistan in 1934-1935. The second folder contains correspondence and notes provided by D.L.R. Lorimer in 1946, to aid Roland Carter, political agent in Gilgit and Carter's own notes.
