The angle forms a very marked prominence, which is deeply fixed into the parietal bone, and partly constitutes the internal protuberance of that bone. , , ^ -a j. , 2 Parietal bone âIn the Dog the parietal bone, formed by two ossific centres only, is distinguished by the great development of the ridges and the parietal protuberance. This last constituted in part by the occipital bone, does not show any lateral excavations at its base- tliey are carried lower, near the summit of the petrous process, on the sides of the' occipital bone. The parieto-temporal canals are continued, notwithstanding, to the base of the protuberance, which they traverse, to open into each otiier in its interior. In the Cat there are scarcely any parietal crests, and the internal protuberance is replaced by two great trans- verse bony plates which separate the cavity of the cerebrum from that of the cerebellum. 3. Frontal bone.âIn carnivora, the external face of this bone presents in its middle a more or less marked de- pression. The orbital arch is incomplete, and there is no superciliary foramen, or mortice on the inner face. The bone is united with the supermaxillaries. 4. Ethmoid hone.âThe ethmoidal fossa is very deep, and the cells very developed and dive
