But it is this study of skull shapes which has led many ethnologists to divide the Caucasian race, not, as it was divided by Huxley, into two, the northern blonds and the Mediterranean and North African dark whites or brunets, but into three. They split his blonds into two classes. They distinguish a northern European type, blond and dolichocephalic, the Nordic; a Mediterranean or Iberian race, Huxley’s dark whites, which is dark-haired and dolichocephalic, and between these two they descry this third race, their brachycephalic race, the Alpine race. The opposite school would treat the alleged Alpine race simply as a number of local brachycephalic varieties of Nordic or Iberian peoples. The Iberian peoples were the Neolithic people of the long barrows, and seem at first to have pervaded most of Europe and western Asia.
