As Professor Schmerling observes, the base of the skull is destroyed,
and the facial bones are entirely absent; but the roof of the cranium,
consisting of the frontal, parietal, and the greater part of the
occipital bones, as far as the middle of the occipital foramen, is
entire or nearly so. The left temporal bone is wanting. Of the right
temporal, the parts in the immediate neighbourhood of the auditory
foramen, the mastoid process, and a considerable portion of the squamous
element of the temporal are well preserved (Fig. 23).
The lines of fracture which remain between the coadjusted pieces of the
skull, and are faithfully displayed in Schmerling's figure, are readily
traceable in the cast. The sutures are also discernible, but the complex
disposition of their serrations, shown in the figure, is not obvious
in the cast. Though the ridges which give attachment to muscles are not
excessively prominent, they are well marked, and taken together with
the apparently well developed frontal sinuses, and the condition of the
sutures, leave no doubt on my mind that the skull is that of an adult,
if not middle-aged man.
The extreme length of the skull is 7.7 inches. Its extreme breadth,
which corresponds very nearly with the interval between the parietal
protuberances, is not more than 5.4 inches. The proportion of the length
to the breadth is therefore very nearly as 100 to 70. If a line be drawn
from the point at which the brow curves in towards the root of the nose,
and which is called the 'glabella' ('a') (Fig. 23), to the occipital
protuberance ('b'), and the distance to the highest point of the arch of
the skull be measured perpendicularly from this line, it will be found
to be 4.75 inches. Viewed from above, Fig. 24, A, the forehead presents
an evenly rounded curve, and passes into the contour of the sides and
back of the skull, which describes a tolerably regular elliptical curve.
The front view (Fig. 24, B) shows that the roof of the skull was very
regularly and elegantly arched in the transverse direction, and that the
transverse diameter was a little less below the parietal protuberances,
than above them. The forehead cannot be called narrow in relation to the
rest of the skull, nor can it be called a retreating forehead; on the
contrary, the antero-posterior contour of the skull is well arched, so
that the distance along that contour, from the nasal depression to the
occi
