The unicorns may have been horses of a good breed, as alluded to by Marco Polo (Yule, i, 166), who states that, “not long ago they possessed in that province a breed of horses from the strain of Alexander’s horse, Bucephalus, all of which had from their birth a particular mark on the forehead”. If we consider that in the time of Timour, the nationality of the inhabitants, the military administration, and the breed of horses in this country, were the same as in the days of Kublai, the ruler had, no doubt, ever been a “None”, Nono, which Marco Polo (_idem_, i, 183) gives as the equivalent for Count. Whatever the origin and primitive significations of this term, I may, perhaps, not be far out in asserting, that in the present instance it designated a noyon or myriarch, such as was Jebe, the vanquisher of the Russians at the battle of the Kalka in 1223 (Berezin, _Nashestvye Mongolov_, 226), and Noë, Duke of Sousdal, who, at about the same period, gave to Julian the missionary, letters of recommendation to Bela IV., King of Hungary (Kunik, _Outch. Zap._, etc., iii, 739), and Tolak Timour the cruel governor of Soudak (_Zap. Odess. Obstschest._, v, 507).—BRUUN. (18A.) When Captain Wood was in Badakshan, he was told that the valley of Meshid was extremely populous in former times, and a legend was current to the effect that it used to be greatly infested with scorpions (_Journey to the Source of the River Oxus_, 1872). Colonel Yule thinks, that if the existence of unicorns was not a mere fable, the animal referred to was probably the rhinoceros, at that time common in the country near Peshawur—not very far from Badakshan.—ED. CHAPTER XXXIV. (1.) “Marburtirudt.”—These measurements agree so exactly with the dimensions to be found in Herodotus, who gives the height of the walls of Babylon at 200 cubits and their thickness at 50 cubits, that the extent of the city, 480 stadia, was probably obtained from the same source. But four stadia do not make one Italian mile. The Italian mile is equal to eight stadia, 480 stadia are, therefore, 60 Italian, or 55-1/5 English miles, no great difference from the 75 miles or 25 leagues noted in the text as being the extent of the wall of Babylon.
