Three races are traced in this period. One, identified by skeletons found at Mentone and by certain statuettes, was negroid in character. Probably there was an occasional immigration from Africa. Another race (Cro-Magnon) was very tall, and seems to represent an invasion from some other part of the earth toward the close of the Old Stone Age. The third race, which is compared to the Eskimo, and had a stature of about five feet, seem to be the real continuers of the Palaeolithic man of Europe. Curiously enough, we have less authentic remains of this race than of its predecessor, and can only say that, as we should expect, the ape-like features--the low forehead, the heavy frontal ridges, the bulging teeth, etc.--are moderating. The needles we have found--round, polished, and pierced splinters of bone, sometimes nearly as fine as a bodkin--show indisputably that man then had clothing, but it is curious that the artist nearly always draws him nude. There is also generally a series of marks round the contour of the body to indicate that he had a conspicuous coat of hair. Unfortunately, the faces of the men are merely a few unsatisfactory gashes in the bone or horn, and do not picture this interesting race to us. The various statuettes of women generally suggest a type akin to the wife of the Bushman. We have, in fine, a race of hunters, with fine stone knives and javelins. Toward the close of the period we find a single representation of an arrow, which was probably just coming into use, but it is not generally known in the Old Stone Age. One of the drawings seems to represent a kind of bridle on a horse, but we need more evidence than this to convince us that the horse was already tamed, nor is there any reason to suppose that the dog or reindeer had been tamed, or that the ground was tilled even in the most rudimentary way. Artistic skill, the use of clothing and fire, and a finer feeling in the shaping of weapons and implements, are the highest certain indications of the progress made by the end of the Old Stone Age.
