With an average height of 6 feet 1-1/2 inches, these cave-dwellers may be said to demonstrate one of the most striking traits of the Crô-Magnon race. In the proportions of the limbs and in the great size of the upper part of the chest these men are removed from the modern European type and approach some of the African negroid types, although there is not the least resemblance to the negro type in the skull or in the dentition. In contrast with the Neanderthals are three characters of the limbs: the leg was very long in comparison with the arm; they show a remarkable lengthening of the forearm in proportion to the upper arm and a still more remarkable lengthening of the lower leg or shin-bone in proportion to the thigh-bone; the tibia has an index of 81-86 per cent as compared with the femur, which is relatively greater than that of the average modern European, with a tibiofemoral index of 79.7 per cent. This long shin-bone indicates that these men were swift of foot, quite in keeping with their undoubted nomadic habits and wide distribution. The flatness of the tibia, which is strongly marked in 62 per cent of the skeletons, may well be due to the habit of squatting while engaged in fashioning flints and in other industrial occupations. The leg, long in comparison with the arm, and the thigh-bone, strongly developed, are both characters of a hunting race. The foot has a very protruding heel, but the sole and the toes are of moderate length. The hip-girdle is of a type which has nothing negroid about it, but is as fine as that of the most civilized whites; it is marked by its strength, the augmentation of all the vertical and transverse diameters, and the reduction of the anteroposterior diameters. The shoulders are exceptionally broad. The fact that the arms are relatively short as compared with the legs is also a high racial character. The upper arm is very robust, and in some cases the left arm is more largely developed, in others the right. In all the skulls from these grottos near Mentone, the face shows the essential features of the Crô-Magnon race, its breadth being due to the development of the cheek-bones and the zygomatic arches, for the upper jaws are narrow, and the nose is thin or leptorhine. At the root the nose shows a marked depression, but it rises immediately to a considerable prominence; it thus undoubtedly had an aquiline profile. The orbits always present the form of a long rectangle, so characteristic of the race along the Vézère. All these characters leave no doubt of the racial affinity of the skeletons from the Grottes de Grimaldi with the original Crô-Magnon type. It must be concluded, therefore, that certain peculiar features noted in the type of the 'old man of Crô-Magnon' are purely individual, and that we are not justified in assuming the admixture of a foreign element to account for the weakness of some characteristics which we notice in the majority of the Crô-Magnon subjects from the caves of Grimaldi.
