Note 9 — Relation of the Voyage to Luzon
Reading edition
Cafre (or Kafir): a term applied by Mahometans to the heathen natives of conquered countries; it means “infidels.” From this originated the name Kafiristan (“country of infidels”), applied to the region north of the Punjaub of India and south of the Hindu-Kush Mountains; its people are called Kafirs. See Yule's Cathay, vol. ii, p. 554.
