There has been much confusion among anthropologists respecting the distinction of this from the preceding age. The Cro-magnon race has been classed as neanthropic, and has been confounded with a very dissimilar people which succeeded it after an interval of some duration. The gap between the disappearance of the earlier race and the arrival of the newer has thus been overlooked, and no account has been taken of the great intervening faunal and geographical changes. This has arisen from neglecting or being unable to appreciate the geological part of the evidence; and the somewhat lamentable result has been that it is difficult for the ordinary reader to arrive at any certainty, in the midst of conflicting statements all based on imperfect data. In these circumstances it will be well to begin this chapter with some examples of the relations of these different races.
At Grenelle, near Paris, on the river Seine, there is a succession of old inundation beds of that river, extending from the oldest part of the anthropic to modern times, and furnishing what may be regarded as a chronological series for Northern France, as many human remains have been from time to time deposited on this old eddy of the Seine and buried under newer accumulations. Belgrand has shown that in the lowest gravels of this deposit the long-headed Canstadt man is alone found. Immediately above this occur remains of the Cro-magnon type, and these are associated with and overlain by beds holding large stones or erratic blocks, a monument perhaps of the physical disturbances closing the palanthropic age. Above these the next remains are those of a race of men of smaller stature and with less elongated heads, which we shall find belong to the neanthropic age. Here, as Quatrefages points out, we have a distinct stratigraphical succession, which accords with that in other localities.
If we now turn to England we may select from other examples the Cresswell caves, so carefully explored by Dawkins and Mello, and in which we have well-ascertained evidence from fossils as well as from superposition. Without going into the details as to the several chambers and passages in these caverns, we find as the result of the whole the following succession in ascending order:
1. White calcareous sand, a deposit from water, but with no animal remains.
2. Stiff red clay with blocks of limestone, and in places underlaid by a ferruginous sand. These beds, of which the red clay is the principal, contain bones of rhinoceros leptorhinus, hippopotamus, bison, bear, hyena and fox, but no human remains. Dawkins, however, shows that in other caves farther south some rude flint implements show that man had already appeared in England, though he may not have made his way as far north as Yorkshire.
3. Above this lies a stratum of red sandy cave earth, in which occur the bones of the mammoth and the woolly rhinoceros, the horse, the bison, the bear, and the hyena, but the leptorhine rhinoceros is gone. The bones are gnawed by hyenas, and there are rude quartzite implements. Over this, and representing the later part of the palanthropic age, corresponding to some of the French, Belgian, and Lebanon caves, are an upper cave earth and breccia, rich in 'palæolithic' flint implements and bones of the animals of the mammoth age.
4. Above this, in the surface soil and disturbed portions of the underlying beds, are remains of the neanthropic period, including twelve species of modern animals, but with no trace of the great extinct quadrupeds. Connected with these were human skulls of the same type found in the ancient burial barrows of England, and belonging to races still extant. The Cresswell caves give no bones of palæocosmic men, but they very well show the succession of the early period of mild climate, the later severe climate, the extinction of the old animals contemporary with the earliest men, and the final succession of modern men and animals to the now insular Britain, which, in the times represented by the beds one, two, and three above mentioned, was a part of the mainland of Europe.
FLINT FLAKES OF TWO TYPES FROM PALANTHROPIC AND NEANTHROPIC CAVES IN THE LEBANON
But perhaps the most interesting views of the succession of early men and the gap between the palanthropic and neanthropic periods are presented by the Belgian caves explored by Schmerling and Dupont. The latter has excavated more than sixty caverns, and has carefully noted the mode of occurrence of their contents, collecting at the same time a vast number of bones and implements, now admirably arranged in the museum of Brussels. In Belgium the earlier anthropic period has been characterised as that of the mammoth. The beginning of the neanthropic is still a reindeer age, though that animal was apparently becoming rare. It existed, as we know, in Central Europe till the time of Cæsar.
