Note 1 — Chapter XIII · NAGÂRA. FESTIVAL OF BUDDHA’S SKULL-BONE. OTHER RELICS, AND HIS SHADOW.
James Legge translation
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.
