[Illustration: Fig. 11. Contours of two skulls, _A_ of a New Guinea man; _B_ of an European woman. The angle _B.PR.P_ measures the degree of prognathism, and in this respect, the two specimens are strongly contrasted. (From specimens in the Cambridge Museum.)] Such are the more easily recognisable features of the skull. It will be understood that many more details remain for discussion. But within the allotted space, two only can be dealt with. The capacity of the brain-case is surprisingly large, for it is estimated at 1600 cubic centimetres: from this figure (which will be the subject of further discussion in the sequel) it appears that the man of La Chapelle was amply provided with cerebral material for all ordinary needs as judged even by modern standards. In the second place, MM. Boule and Anthony, not content with a mere estimate of capacity, have published an elaborate account of the form of the brain as revealed by a cast of the interior of the brain-case. As the main result of their investigations, they are enabled to record a list of characters indicative of a comparatively lowly status as regards the form of the brain, although in actual size it leaves little to be desired. The principal points of interest in the remainder of the skeleton refer in the first instance to the estimate of stature and the evidence provided as to the natural pose and attitude of the individual. Using Professor Pearson's table, I estimate the stature as being from 1600 to 1620 mm. (5ft. 3in. or 5ft. 4in.), a result almost identical with the estimate given for the Neanderthal man. In both, the limb bones are relatively thick and massive, and by the curvature of the thigh-bones and of the upper parts of the shin-bones, a suggestion is given of the peculiar gait described by Professor Manouvrier as 'la marche en flexion'; the distinctive feature consists in an incompleteness of the straightening of the knee-joint as the limb is swung forwards between successive steps. The bones of the foot are not lacking in interest, and, in particular, that called astragalus is provided with an unusually extensive joint-surface on its outer aspect. In this respect it becomes liable to comparison with the corresponding bone in the feet of climbing animals, whether simian or other. That these features of the bone in question are not peculiar to the skeleton from La Chapelle, is shewn by their occurrence in bones of corresponding antiquity from La Quina (Martin, 1911) and (it is also said) from La Ferrassie (Boule, L'Anthropologie, Mai-Juin, 1911). _Homo mousterensis hauseri_ (_Dordogne_)
