faster or slower pace than that of other Mammalia. And if that is so, we are warranted in the supposition that the genus _Homo_, if not the species which the courtesy or the irony of naturalists has dubbed _sapiens_, was represented in Pliocene or even Miocene times.... There is no reason to suppose that the genus _Homo_ was confined to Europe in the Pleistocene age; it is much more probable that this, like other Mammalian genera of that period, was spread over a large extent of the surface of the globe. At that time, in fact, the climate of regions nearer the equator must have been far more favourable to the human species, and it is possible that under such conditions it may have attained a higher development than in the north." (_Huxley._) Professor Huxley points out also, in the interesting article "The Aryan Question," in _The Contemporary Review_ for November, 1890, from which we have taken the above extracts, that the Irish river-bed skulls, belonging to a dark-haired, long-headed race, and those of the Frisians, the blond, long-headed race, now living on the North German coast, unmistakably approach the Neanderthal and Spy type in many of their distinctive {223}characters, "a sure indication" of the physiological continuity with the Pleistocene Neanderthaloid Men. The skulls of some of the Australian aboriginals and of the broad-headed people of Borreby, in Denmark, also present a remarkable similarity to the Neanderthal skull--perhaps an indication that those are characters of a stage in the pedigree of the human species before it differentiated into any of the existing races.
