Letter from Emily Overend Lorimer to Sidney John Duly to thank him for his delightful and entertaining letter which had cheered David in his illness. She asks that he will write again and that Duly will keep his letters from Lorimer as he rarely writes with freedom to anyone. Lorimer had been ill for five weeks with fever but is now recovering. The people are friendly and of goodwill and happy to talk about themselves, so she is hopeful of maximum information in the time available. She writes that they were delighted that Bunny could go with Duly to South Africa and to thank her for the postcard from Liverpool. She also writes that 'Lock' may send his Introductions to the 2 volumes of Bu, Grammar and Texts. Written from Aliabad, Hunza. Typed with handwritten annotations and signature, 2 pieces, 2 sides, dated 4 September 1934.
