Having shown the existence in Europe of three distinct subspecies of man and a single predominant group of languages called the Aryan or synthetic group, it remains to inquire to which of the three races can be assigned the honor of inventing, elaborating and introducing this most highly developed form of human speech. Our investigations will show that the facts point indubitably to an original unity between the Nordic or rather the Proto-Nordic race and the Proto-Aryan language or the generalized, ancestral, Aryan mother tongue. Of the three claimants to the honor of being the original creator of the Aryan group of languages, we can at once dismiss the Mediterranean race. The members of this subspecies on the south shores of the Mediterranean, the Berbers and the Egyptians, and many peoples in western Asia speak now and have always spoken Anaryan tongues. We also know that the speech of the original Pelasgians was not Aryan, that in Crete remnants of Pre-Aryan speech persisted until about 500 B. C. and that the Hellenic language was introduced into Ægean countries from the north. In Italy the Etruscan in the north and the Messapian in the south were Anaryan languages and the ancestral form of Latin speech in the guise of Umbrian and Oscan came through the Alps from the countries beyond. In Spain a Celtic language was introduced from the north about 500 B. C. but with so little force behind it that it was unable to replace entirely the Anaryan Basque language of at least a portion of the aborigines. In Britain, Aryan speech was introduced about 800 B. C. and in France somewhat earlier. In central and northern Europe no certain trace of the Anaryan languages at one time spoken there persists, except among the Lapps and in the neighborhood of the Gulf of Finland, where Non-Aryan Finnic dialects are spoken to-day by the Finlanders and the Esthonians. We thus know the approximate dates of the introduction of Aryan speech into western and southern Europe and that it came in through the medium of the Nordic race. In Spain and in the adjoining parts of France nearly half a million people continue to speak an agglutinative language, called Basque or Euskarian. In skull shape these Basques correspond closely with the Aryan-speaking populations around them, being dolichocephalic in Spain and brachycephalic or pseudo-brachycephalic in France. In the case of both the long skulled and the round skulled Basques the lower part of the face is long and thin, with a peculiar and pointed chin and among the French Basques the skull is broadened in the temporal region. In other words, their faces show certain secondary racial characters which have been imposed by selection upon a people composed originally of two races of independent origin, but long isolated by the limitations of language.
