Our Early Ancestors, an Introductory Study of Mesolithic, Neolithic and Copper Age Cultures in Europe and Adjacent Regions, by M.C. Burkett, M.A., F.S.A., F.G. 1876
The invaders differed somewhat from the former inhabitants of the land. The Neolithic folk seem to have been of moderate stature, long-headed, oval faced, narrow nosed, with small features. They were not at all powerfully built race. The newcomers on the other hand- according to Abercromby- were characterized by short square skull showing a great development of the superciliary ridges and eyebrows. The cheek-bones, nose and chin were prominent and the powerful lower jaw was supplied with large teeth. They were a tall, strongly built race and must have presented- at any rate as far as men were concerned- a fierce, brutal appearance. The dead were buried in round barrows, inhumation being practiced. They knew about the use of copper and introduced into England the beaker type pot

Here again there is no lack of skulls and skeletons, and the descriptions of them are many. In the barrows of this period, we find two classes of skulls, long and broad. The former may be those of the earlier people, the latter those of a race which had invaded the country. Or the collection may be explained without supposing the arrival of a different race, but these are points into which it is impossible to enter here. Suffice it to say that the skulls regarded as typical of this period are brachycephalic, of large size and with well-formed brow. There are salient ridges above the eyes, but these are not the monsterous projections of the Neanderthal type. One gains the idea that the cast of the countenance of the possessors of these skulls must have been much more fierce and commanding than that of the milder race which preceded them.
