Yule had no more predilection for the Monastic Orders than most of his countrymen, but his sense of justice was shocked by the cruel incidence of the measure in many cases, and also by the harshness with which both it and the punishment of suspected insurgents was carried out. Cholera was prevalent in Italy that year, but Sicily, which had maintained stringent quarantine, entirely escaped until large bodies of troops were landed to quell the insurrection, when a devastating epidemic immediately ensued, and re-appeared in 1867. In after years, when serving on the Army Sanitary Committee at the India Office, Yule more than once quoted this experience as indicating that quarantine restrictions may, in some cases, have more value than British medical authority is usually willing to admit. In 1867, on his return from London, Yule commenced systematic work on his long projected new edition of the _Travels of Marco Polo_. It was apparently in this year that the scheme first took definite form, but it had long been latent in his mind. The Public Libraries of Palermo afforded him much good material, whilst occasional visits to the Libraries of Venice, Florence, Paris, and London, opened other sources. But his most important channel of supply came from his very extensive private correspondence, extending to nearly all parts of Europe and many centres in Asia. His work brought him many new and valued friends, indeed too many to mention, but amongst whom, as belonging specially to this period, three honoured names must be recalled here: Commendatore (afterwards Baron) CRISTOFORO NEGRI, the large-hearted Founder and First President of the Geographical Society of Italy, from whom Yule received his first public recognition as a geographer, Commendatore GUGLIELMO BERCHET (affectionately nicknamed _il Bello e Buono_), ever generous in learned help, who became a most dear and honoured friend, and the Hon. GEORGE P. MARSH, U.S. Envoy to the Court of Italy, a man, both as scholar and friend, unequalled in his nation, perhaps almost unique anywhere.
