It is the large proportional size of the facial bones and the great projection of the jaws which confers upon the Gorilla's skull its small facial angle and brutal character. The line 'b' indicates the plane of the tentorium, which separates the cerebrum from the cerebellum; 'd', the axis of the occipital outlet of the skull.
If the angle made by the line 'b c'. with 'a b'., be called the 'occipital angle, and the angle made by the line 'a d'. with 'a b'. be termed the 'olfactory angle, and that made by 'i T'. with 'a b'. the 'tentorial angle, then all these, in the mammal in question, are nearly right angles, varying between 80 degrees and 110 degrees.
Each may adopt the hypothesis which seems to him most probable: for my own part, I hold it to be demonstrated that this cranium has belonged to a person of limited intellectual faculties, and we conclude thence that it belonged to a man of a low degree of civilization: a deduction which is borne out by contrasting the capacity of the frontal with that of the occipital region.
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.
Hemorrhage was profuse from the temporal, occipital, and posterior auricular arteries, which were tied. The patient was seen three-quarters of an hour after the injury, and the mangled scalp was thoroughly washed in warm carbolized water, and stitched back in position, after the hair was cut from the outer surface.
The occipital region of the skull, also, not unfrequently becomes less prominent; so that it not only fails to project beyond a line drawn perpendicular to the hinder extremity of the glabello-occipital line, but even, in some cases, begins to shelve away from it, forwards, almost immediately.
The imperfect definition of this fissure in the majority of human brains, as compared with its remarkable distinctness in the brain of most Quadrumana, is owing to the presence, in the former, of certain superficial, well marked, secondary convolutions which bridge it over and connect the parietal with the occipital lobe.
"The bullet entered at the juncture of the nasal and frontal bones," explained Harley, rapidly, "and it came out between the base of the occipital and first cervical. Without going into unpleasant surgical details, the wound was a perfectly straight one. There was no ricochet." "I understand that a regulation rifle was used?" "Yes," said Inspector Aylesbury; "we have it."
Professor Huxley afterwards studied the cast with the object of assisting me to give illustrations of it in this work, and in doing so discovered what had not previously been observed, that it was quite as abnormal in the shape of its occipital as in that of its frontal or superciliary region. Among six or seven human skeletons, portions of which were collected by Dr.
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.
