79:4.3

The Aryans made very little racial impression on India except in the northern provinces. In the Deccan their influence was cultural and religious more than racial. The greater persistence of the so-called Aryan blood in northern India is not only due to their presence in these regions in greater numbers but also because they were reinforced by later conquerors, traders, and missionaries. Right on down to the first century before Christ there was a continuous infiltration of Aryan blood into the Punjab, the last influx being attendant upon the campaigns of the Hellenistic peoples.
