As well as can be estimated, the parietal longitudinal arc, or length of the sagittal suture, is 5″·2. The vertical transverse arc, or that drawn from one auditory foramen to the other, over the point of junction of the coronal and sagittal sutures, is 12″·2, the parietal 13″, and the occipital 12″·2. In the temporal bone, the external auditory foramen is large, the mastoid process of moderate size, but the digastric fossa is wide and deep. The channels for the middle meningeal artery and its branches are large and deep; and very deep depressions on the sides of the sagittal suture show that the _glandulæ Pacchioni_ must have been greatly developed. The bone is very thin, and with scarcely a trace of _diploë_ where its structure is visible. None of the sutures, however, which are strongly serrated, are in the slightest degree closed, although, as I should imagine, the skull must have been that of a man beyond the middle period of life. II. _The Thigh-bones._--Two of these bones, which, though much alike, differ sufficiently to show that they did not belong to the same individual, are decidedly carinate. No. 1 wants the upper and lower ends. The least circumference of the shaft, which is at a point about 3½ inches below the _trochanter minor_, is 3″·2. That process, as well as all the other muscular impressions, is strongly developed; and that for the insertion of the _gluteus maximus_ is peculiar in presenting the form of a deep elongated pit instead of a roughened elevation as usual. The antero-posterior and transverse diameters of the shaft, about 1½ inches below the _trochanter minor_, are ·85 × 1·4; and the shaft at this part, like that of the above-described from Perthi-Chwareu, presents a rather acute or narrow external and internal border instead of the usual more rounded form. Lower down, the shaft becomes strongly carinate; and, owing to the flattened form of the anterior surface, its transverse section affords a subtriangular figure (fig. 55). The walls, or cortical substance, are rather thicker than usual, and the substance of the bone is dense and hard. [Illustration: FIG. 55.] [Illustration: FIG. 56.] No. 2 is very similar in character to the foregoing, but is not quite so much compressed in the upper part, measuring ·8 × 1·2. Nevertheless the inner border is very acute, and the outer more so than in the common form of _femur_. The shaft lower down is not so strongly carinate as it is in the former instance, but is still so in some degree (Fig. 56); and the walls (or cortical substance) are still thicker in proportion.
