It has been often remarked that the name, or one very similar, occurs more than once in the East as an ethnical and geographical designation.  Thus we find Camboja a territory in India, Kamoj a tribe of the Kafirs in Cabul; and a territory named Cambysene, situated in the north on the Kur, is known to Greek geographers.  In the same region there was a river called Cambyses, the modern Jora.  Perhaps with Spiegel (Eranische Alterthumskunde, vol. ii. p. 294) we may regard the personal name Kambujiya as originally an adjective, meaning belonging to Kambuja.
