ose. The forehead is
narrow and low, though the middle and hinder portions of the cranial
arch are well developed. Unfortunately, the fragment of the skull that
has been preserved consists only of the portion situated above the
roof of the orbits and the superior occipital ridges, which are greatly
developed, and almost conjoined so as to form a horizontal eminence. It
includes almost the whole of the frontal bone, both parietals, a small
part of the squamous and the upper-third of the occipital. The recently
fractured surfaces show that the skull was broken at the time of its
disinterment. The cavity holds 16,876 grains of water, whence its
cubical contents may be estimated at 57.64 inches, or 1033.24 cubic
centimetres. In making this estimation, the water is supposed to stand
on a level with the orbital plate of the frontal, with the deepest
notch in the squamous margin of the parietal, and with the superior
semicircular ridges of the occipital. Estimated in dried millet-seed,
the contents equalled 31 ounces, Prussian Apothecaries' weight. The
semicircular line indicating the upper boundary of the attachment of the
temporal muscle, though not very strongly marked, ascends nevertheless
to more than half the height of the parietal bone. On the right
superciliary ridge is observable an oblique furrow or depression,
indicative of an injury received during life.* ([Footnote] *This, Mr.
Busk has pointed out, is probably the notch for the frontal nerve.) The
coronal and sagittal sutures are on the exterior nearly closed, and on
the inside so completely ossified as to have left no traces whatever,
whilst the lambdoidal remains quite open. The depressions for the
Pacchionian glands are deep and numerous; and there is an unusually
deep vascular groove immediately behind the coronal suture, which, as it
terminates in the foramen, no doubt transmitted a 'vena emissaria'. The
course of the frontal suture is indicated externally by a slight
ridge; and where it joins the coronal, this ridge rises into a small
protuberance. The course of the sagittal suture is grooved, and above
the angle of the occipital bone the parietals are depressed.
