His work as a member of the Army Sanitary Committee, brought him into communication with Miss Florence Nightingale, a privilege which he greatly valued and enjoyed, though he used to say: “She is worse than a Royal Commission to answer, and, in the most gracious charming manner possible, immediately finds out all I don’t know!” Indeed his devotion to the “Lady-in-Chief” was scarcely less complete than Kinglake’s. In 1880, Yule was appointed to the Board of Visitors of the Government Indian Engineering College at Cooper’s Hill, a post which added to his sphere of interests without materially increasing his work. In 1882, he was much gratified by being named an Honorary Fellow of the Society of Antiquaries of Scotland, more especially as it was to fill one of the two vacancies created by the deaths of Thomas Carlyle and Dean Stanley. Yule had been President of the Hakluyt Society from 1877, and in 1885 was elected President also of the Royal Asiatic Society. He would probably also have been President of the Royal Geographical Society, but for an untoward incident. Mention has already been made of his constant determination to judge all questions by the simple touchstone of what he believed to be right, irrespective of personal considerations. It was in pursuance of these principles that, at the cost of great pain to himself and some misrepresentation, he in 1878 sundered his long connection with the Royal Geographical Society, by resigning his seat on their Council, solely in consequence of their adoption of what he considered a wrong policy. This severance occurred just when it was intended to propose him as President. Some years later, at the personal request of the late Lord Aberdare, a President in all respects worthy of the best traditions of that great Society, Yule consented to rejoin the Council, which he re-entered as a Vice-President. In 1883, the University of Edinburgh celebrated its Tercentenary, when Yule was selected as one of the recipients of the honorary degree of LL.D. His letters from Edinburgh, on this occasion, give a very pleasant and amusing account of the festivity and of the celebrities he met. Nor did he omit to chronicle the envious glances cast, as he alleged, by some British men of science on the splendours of foreign Academic attire, on the yellow robes of the Sorbonne, and the Palms of the Institute of France! Pasteur was, he wrote, the one most enthusiastically acclaimed of all who received degrees.
