Forster conjectures that the original words of
Rubruquis are here
corrupted, and that this passage ought to have been “beyond Tangut,”
instead of beyond Tebet or Thibet; in which case, the countries of
Langa and Solanga, may refer to that of the Lamuts and Solonians, the
ancestors of the Mantschus or Mundschurians.—Voy. and Disc. 108.
 In this supposition Rubruquis was certainly mistaken,
as the Seres of
the ancients appear to have lived in Turkestan, Gete, and Uigur, and
to have then ruled over a great track of eastern central Asia, and may
have extended their commerce to northern China. Hence the original
name of silk was certainly either adopted from or applied to the
intermediate nation, through whom that precious commodity was
transmitted to the western nations.—Forst.
 A jascot is described as a piece of silver weighing
ten marks, so that
the tribute is 15,000 marks daily, or about 5 1/2 millions of marks
yearly, and is equal in weight of silver, to L. 8,650,000 Sterling;
perhaps equal, in real efficacious value, to ten times that sum, and
probably superior to the yearly revenue of all the sovereigns then in
 Singan, or Singan-fu in the province of Shensee.
In the year 1625, a
stone was found here, inscribed with Chinese characters and a Syrian
inscription round the borders, implying, that in the year 636, the
Nestorians had sent Olopuen into China to propagate the gospel; and
that the emperor Tai-sum-ven had approved this step, and allowed the
Christian religion to be propagated through all China, with many other
particulars relative to the history of Christianity in China. This
stone bore to have been erected in 782 by Mar Isdabuzzid, priest, and
Chorepiscopus of Cumdan, the royal city of the east, now Nankin. See a
dissertation on this monument, following Renaudet’s translation of the
two Mahometan travellers, London, 1788, p. 76.—E.
 Mani or Manes is named Thenaoui by the oriental
Christians, and the
sect of Manicheans they call Al-Thenaouib, or those who hold the
doctrines of the two principles. These Tuinians, therefore, of
Rubruquis, are probably the Manicheans.—Forst.
Of Cailac, and the Country of the Naymans.
We departed from the city of Cailac on St Andrew’s day, 30th of November, and in three leagues we found a village of Nestorians, where we went into their church, and sang salve regina, and other hymns, with great joy. In three days after we came to the entrance of that province, not far from the before mentioned sea, which seemed as tempestuous as the ocean, and in which we saw a large island. The water was slightly salt, yet might be drank. Opposite
