We can only note the fact as indicated by the phenomena, and form, or abstain from forming, as we please, hypotheses with respect to its accompanying circumstances.
Besides these two main constituents of the Chaldaean race, there is reason to believe that both a Semitic and an Arian element existed in the early population of the country.

The subjects of the early kings are continually designated in the inscriptions by the title of _kiprat-arbat,_ "the four nations," or _arba lisun,_ "the four tongues." In Abraham's time, again, the league of four kings seems correspondent to a fourfold ethnic division, Cushite, Turanian, Semitic, and Arian, the chief authority and ethnic preponderance being with the Cushites.
The language also of the early inscriptions is thought to contain traces of Semitic and Arian influence; so that it is at least probable that the "four tongues" intended were not mere local dialects, but distinct languages, the representatives respectively of the four great families of human speech.
It would result from this review of the linguistic facts and other ethnic indications, that the Chaldaeans were not a pure, but a very mixed people.

Like the Romans in ancient and the English in modern Europe, they were a "colluvio gentium omnium," a union of various races between which there was marked and violent contrast.

It is now generally admitted that such races are among those which play the most distinguished part in the world's history, and most vitally affect its progress.
With respect to the name of Chaldaean, under which it has been customary to designate this mixed people, it is curious to find that in the native documents of the early period it does not occur at all.

Indeed it first appears in the Assyrian inscriptions of the ninth century before our era, being then used as the name of the dominant race in the country about Babylon.
