James Legge translation
(1) Now in India, Fâ-Hien used the Indian measure of distance; but it is not possible to determine exactly what its length then was. The estimates of it are very different, and vary from four and a half or five miles to seven, and sometimes more. See the subject exhaustively treated in Davids’ “Ceylon Coins and Measures,” pp. 15-17.
