We have thus traces of two primitive or antediluvian races, one probably mild and subsisting on vegetable food, and another fierce, rude and carnivorous, perhaps a product of degeneracy of the former; and a third, or mixed race, of greater physical power and energy than either of the others. This is of course merely a hypothetical reading of the facts, but it is by no means improbable, and would, as we shall see, bring them into close relation with the teachings of history and tradition as to the antediluvian age. The most careful and elaborate studies of these several types have been made by MM. Quatrefages and Hamy. The former sums up the races of fossil or 'quaternary' men as six in number, viz.: (1) The Canstadt; (2) the Cro-magnon; (3) the mesitocephalic race of Furfooz; (4) the sub-brachycephalic race of Furfooz; (5) the race of Grenelle; (6) the race of Truchère. Of these only three (namely, Nos. 1, 2, and 6) properly belong to the palanthropic age. The races of Furfooz[24] and of the upper beds of Grenelle are neanthropic, because they are found with the animal remains of that age, and they resemble in cranial characters the neanthropic peoples. [24] Noticed later, in Chapter VII. The Canstadt and Cro-magnon races resemble each other in being long-headed or dolichocephalic, and in having strong and coarsely-made facial bones, but the Canstadt race has a comparatively low fore-*head with strong superciliary arches, and round eye-sockets. The Cro-magnon race has a brain-case of more than ordinary capacity, a more elevated fore-*head, and eye-sockets singularly elongated horizontally. Broca has measured the cubic contents of the Cro-magnon skull, and gives as the result 1,590 cubic centimetres, or 119 centimetres more than the average of 125 modern Parisian skulls. The Canstadt men were of moderate stature, but strongly built and muscular. The Cro-magnon race was of great stature, some skeletons approaching to seven feet in height, and affording evidence of immense muscular development. [Illustration: SKULL FROM TRUCHÈRE, SHOWING A PECULIAR PALANTHROPIC TYPE ALLIED TO NEANTHROPIC RACES (after Quatrefages)] The race of Truchère is represented by only a single skull; but Quatrefages vouches for it as belonging to the age of the mammoth. It is a well-formed brachycephalic cranium of unusually great internal capacity, and would be regarded anywhere as indicating a race of high and refined cerebral endowment. If really of the mammoth age, it may have belonged to a straggler or captive from a higher and more cultured tribe, introduced accidentally into a sepulchre of the Cro-magnon period. It connects itself with the speculation in the preceding pages as to the existence of such a race. This skull resembles, as we should expect, the type of the neanthropic men who spread over the earth at the beginning of that later age.
