In the following paper the term ‘Ancient Briton’ is applied to the whole of the mixed races which inhabited this island prior to the Teutonic irruption. They consisted of the two Celtic families (the Gaels and the Brythons, or Cymri), and the pre-Celtic races. On the divisions of the latter anthropology has not yet decidedly pronounced, though it seems probable that they were not homogeneous. In any case the principal pre-Celtic type at present discovered, which may generically be termed Iberian, and which appears to correspond with that of the original neolithic inhabitants, was dark, small, and short, the average stature being only sixty-three inches. The pure Celt, on the other hand, was extremely tall, the average stature being sixty-nine inches, and that of the Saxon sixty-seven. This agrees with the statements of Polybius, Strabo, and Ammianus Marcellinus as to the height of the Celt, and at the same time accounts for the Britons being spoken of as short and thick-set. For in this country the Celt was found mixed to a large extent with the short pre-Celtic race or races. The people, therefore, that the Saxons had to contend with were, on an average, of shorter stature than themselves. They varied, no doubt, in different parts of the country, but probably the purest Iberian blood, and consequently the shortest stature, would be at the bottom of the social scale. If any pure Celtic blood remained in the country it would be chiefly in the east; and it is to the permanence of this, rather than to the superior stature of the Angles over the rest of the invaders, that I attribute the height of the present inhabitants of the Anglian districts. The prevailing physiognomy of East Anglia also supports this view; the tall stature, brown hair, grey eye, and arched nose of the pure Celt is not uncommon there.
