attachment of the muscles or bones. That this conclusion may be drawn
from the existence of large frontal sinuses, and a prominence of the
lower frontal region, is confirmed in many ways by other observations.
By the same characters, according to Pallas, the wild horse is
distinguished from the domesticated, and, according to Cuvier, the
fossil cave-bear from every recent species of bear, whilst, according
to Roulin, the pig, which has become wild in America, and regained a
resemblance to the wild boar, is thus distinguished from the same animal
in the domesticated state, as is the chamois from the goat; and,
lastly, the bull-dog, which is characterised by its large bones and
strongly-developed muscles from every other kind of dog. The estimation
of the facial angle, the determination of which, according to Professor
Owen, is also difficult in the great apes, owing to the very prominent
supra-orbital ridges, in the present case is rendered still more
difficult from the absence both of the auditory opening and of the
nasal spine. But if the proper horizontal position of the skull be
taken from the remaining portions of the orbital plates, and the
ascending line made to touch the surface of the frontal bone behind the
prominent supra-orbital ridges, the facial angle is not found to exceed
56 degrees.* Unfortunately, no portions of the facial bones, whose
conformation is so decisive as regards the form and expression of the
head, have been preserved. The cranial capacity, compared with the
uncommon strength of the corporeal frame, would seem to indicate a small
cerebral development. The skull, as it is, holds about 31 ounces of
millet-seed; and as, from the proportionate size of the wanting bones,
the whole cranial cavity should have about 6 ounces more added, the
contents, were it perfect, may be taken at 37 ounces. Tiedemann
assigns, as the cranial contents in the Negro, 40, 38, and 35 ounces.
The cranium holds rather more than 36 ounces of water, which
corresponds to a capacity of 1033.24 cubic centimetres. Huschke
