In the last number (vol. v. parts ii.–iv.) of the Zapiski of the Oriental Section of the Russian Archæological Society (St. Petersburg, 1891), we find an account of two stones inscribed with Chinese characters, discovered on the Upper Orkhon, near the ruins of Kara Balgassun, among a quantity of other remains, by M. Yadrintsef, during his expedition last summer in North-eastern Mongolia, and forwarded by him to St. Petersburg. Here they were carefully examined by M. E. Koch, who reports that the stones are unfortunately only fragments of a much larger monument, and that it is impossible to say whether they both formed part of the same though they were found in close juxtaposition and their contents would apparently support such a conjecture. Most of the characters are easily legible, being very similar in style to those in present use in China, but owing to the fact of the stones being of grey granite, much weatherworn in places, and the age of the inscriptions (upwards of one thousand years old), there are difficulties in deciphering them. They refer to the period of the T'ang dynasty, or, to be more precise, to the time when the Uighurs were dominant in Northern Mongolia; The characters differ in some instances from those in general use and a few are quite illegible. Where these occur dots are inserted in the text. All the lines want both beginning and end.
