This skull, so remarkable for its fine proportion, is also remarkable for its capacity. According to M. Broca, who could only work under precautions calculated to diminish the amount, it is equal to at least 1590 cubic centimetres (96·99 cubic inches). I have already remarked that this number is far higher than the mean taken from modern Parisians; it is equally so in comparison with the other European races. Thus, in the savage of quaternary ages, who had to fight against the mammoth with stone weapons for arms, we find all those craniological characters generally considered as the sign of great intellectual development. The features of the face are not less striking than those of the skull. In the heads which M. Pruner Bey calls _harmonic_, a face elongated from above downward corresponds to a skull elongated from behind forward. When there is a disagreement between these proportions the head is _dysharmonic_. This latter character is very strongly marked in the old man of Cro-Magnon. The bizygomatic transverse diameter acquires an extent rare even in harmonic brachycephali. In his case the facial index descends as low as 63. This exaggeration in breadth is present also in all the upper and medial parts of the face. The orbits, almost rectilinear at their extremities, are remarkable for their slight elevation, being on the other hand very long. The orbital index descends lower than M. Broca has ever known it to be: it is only 61. But this tendency to breadth does not extend to the medial regions or to the inferior portion of the face. The nose, the bones of which are boldly projected forward and constitute a strongly marked protuberance, is narrow; from its index, 45·09, it places the old man of Cro-Magnon amongst the lepthorhini of M. Broca. The superior maxillary bone is equally narrowed relatively to the face which it terminates, and the alveolar arch is projected outward in such a manner as to produce a very decided prognathism. The inferior maxillary bone is especially remarkable for the breadth of its ascending branches which, according to the investigation of M. Broca, surpass in this respect all other known human jaw-bones. The breadth in question is 49 m.m. (1·93 inch). Far from being obliterated and retreating, as in the Canstadt race, the slightly triangular chin projects forwards.
