It was a language more like the unclassified caucasic language groups than any others that now exist.
Undoubtedly the term "caucasic" cannot be defended on ethnical grounds.
Beyond the mainland and Ceylon no caucasic peoples of Aryan speech are known to have ranged in neolithic or prehistoric times.
Asia is mainly peopled by races belonging to two great ethnographic types, the caucasic or fair type, and the Mongolic or yellow.
In Caucasia, there are many distinct forms of speech, yet all the peoples belong to the caucasic division of mankind.
Certainly this caucasic division consists apparently of the most heterogeneous elements, more so than perhaps any other.
Probably they are to be reckoned as Dravidians, a very remote blend of caucasic and Negro man.
