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. 22), 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. 23, 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. 23, 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 occipital protuberance, measures about 13.75 inches.
The transverse arc of the skull, measured from one auditory foramen to
the other, across the middle of the sagittal suture, is about 13
inches. The sagittal suture itself is 5.5 inches long.
