mountain chains, or they crossed over from the high 

 land of Thibet. That the movement was in a great 

 part from north-west to south-east, is proved by the 

 presence of Gangarides, in the valley of the Brama- 

 putra, where, in other respects, the foreign element in 

 the first population was eastern Caucasian or Malay. 

 Who the bearded tribes were, that originally spread 

 over China, was sufficiently shown in the notice of the 

 Mongolic and Finnic nations, not to be again repeated, 

 although we have on the south of Asia nations simi- 

 larly constituted, but further debased by certain Papua 

 intermixtures, and all feel the different influence of a 

 southern, and often a marine climate. 



The infusion of northern elements is strikingly- 

 proved by the predominating presence of Sanscrit in 

 all the dialects of India, although variously debased by 

 forms of speech of indigenous origin, Parbatyia, Naja, 

 Dravira, Bheel, Nishada, and Yadhu, &c., upon which 

 it was ingrafted. As the invaders came through the 

 gorges of the mountains in successive swarms, and not 

 always from the same point, they subjugated not only 

 the black aborigines, but also the mixed tribes of their 

 former conquerors, leaving only that portion in free- 

 dom which could retreat to inaccessible mountain dis- 

 tricts, to recede from the civilization they might have 

 had before their political ruin ; and either pure or 

 already under the rule of masters not of the kindred 

 stock. The older invaders seem to have been denomi- 

 nated Chasas, equivalent to the western term Asi or 

 Asen, highlanders, which is also the meaning of Guras.
