The whilom tyranny of the Sanskritists is happily overpast, and it is seen that hasty philological deductions require to be systematically checked by… - Isaac Taylor

The Aryan invaders, few in number, who were settled on the banks of the Upper Indus, are found gradually advancing to the south and the east in continual conflict with the Dasyu or dark-skinned aborigines, who spoke a strange language, worshipped strange gods, and followed strange customs, till finally the barbarians are subdued and admitted into the Aryan state as a fourth caste, called the "blacks," or Sudras. The higher civilisation and the superior physique of the northern invaders ultimately prevailed, and they imposed their language and their creed on the subject tribes; but the purity of the race was soiled by marriage with native women, the language was infected with peculiar Dravidian sounds, and the creed with foul Dra- vidian worships of Siva and Kali, and the adoration of the lingam and the snake. The Aryanisation of Europe doubtless resembled that of India. The Aryan speech and the Aryan civilisation prevailed, but the Aryan race either disappeared or its purity was lost.

Taylor rejected the association between race and language altogether. He found the theory of a single Aryan migration out of Asia “extremely shadowy … [resting] on no solid grounds whatever” (1890: 17).
