The Kang-Mou (tom iii. p. 447) ascribes to their conquests a space of 14,000 lis. According to the present standard, 200 lis (or more accurately 193) are equal to one degree of latitude; and one English mile consequently exceeds three miles of China. But there are strong reasons to believe that the ancient li scarcely equalled one-half of the modern. See the elaborate researches of M. d'Anville, a geographer who is not a stranger in any age or climate of the globe. (Memoires de l'Acad. tom ii. p. 125-502. Mesures Itineraires, p. 154-167 )
