The two races of Furfooz, like that of Grenelle, have a certain family resemblance, which does not exclude the existence of distinctive characters. Thus, in the mesaticephalic race of Furfooz the antero-posterior arc of the skull produces above the small but well marked superciliary ridges, a very retreating forehead, and is continued with no further inflexion than a slight depression at the sutures. The face is broad and the index almost the same as that of the race of Cro-Magnon. On account of the shortening of the skull, the head is, however, _harmonic_, instead of being _dysharmonic_ as in the troglodytes of Périgord. A slightly concave, but sufficiently prominent nose, square orbits, slightly marked canine fossæ, and an almost orthognathous superior maxillary bone complete this face, the bony framework of which has a somewhat finely cut and delicate appearance. In this sub-brachycephalic race of the same locality, the forehead rises in a somewhat perpendicular line to the level of the frontal eminences. The arc then becomes suddenly flattened as far as the first third of the parietal bones where the curve becomes more inflected and is continued with almost unbroken regularity to the foramen magnum of the occipital. We meet with almost the same index in the face; but the orbits and the face are longer, the canine fossæ form deep indentations, the superior maxillary bone projects forward, the teeth follow the same direction, and the prognathism is very striking. In the race of Grenelle, the very prominent glabella and full superciliary ridges give a slightly oblique direction to the base of the forehead. But the arc soon rises and is regularly developed without either projection or depression. The skull, viewed from the face, appears as well proportioned as in profile. The face harmonises with it. The cheek bones are well developed and prominent; the canine fossæ high, but not deep; the orbits approach the square form; the bones of the nose are concave and sufficiently prominent. Finally, the maxillary bone and the teeth are equally prognathous, but less so than in the preceding race. III. The men of Grenelle, and still more those of Furfooz, were of small stature. The former reached a mean of 1·62 m. (5ft. 3·8 in.), but the latter descended to 1·53 m. (5ft. 0·2 in.) This is almost exactly the mean height of the Lapps. Yet this reduced stature would neither exclude the vigour nor the agility necessary to savage populations. The bones of the limbs and trunk are strong, and the eminences and depressions of their surface indicate a very marked muscular development.
