Cranial peculiarities. — Under this head we proceed to notice certain arrangements re- quiring further attention, and in the first place the remarkable sinuses which exist in the skull of the Giraffe. Though these be nothing more than an extension of the Fig. ordinary frontal, ethmoidal and sphenoidal cells, yet their significance is not the less apparent or important when considered in a physiological or teleological point of view. It has been considered necessary to pre- serve the cranium of the Giraffe at present in our possession entire ; consequently, we are unable to offer any account of these sinuses from personal examination, which is the less to be regretted, as Prof. Owen has placed Sectional mew of the cranium of the Giraffe. (From Owen.) on record the following description of this structure *; " The part of the skull to which the elastic ligament is attached is raised considerably above the roof of the cranial cavity by the extension backwards of large sinuses, or air-cells, as far as the occiput. The sinuses commence above the middle of the nasal cavity, and increase in depth and width to beneath the base of the horns, where their vertical extent equals that of the cere- bral cavity itself. The exterior table of the skull, thus widely separated from the vitreous table, is supported by stout bony partitions, extended chiefly in the transverse direction, and with an oblique and wavy course. Two of the most remarkable of these bony walls are placed at the front and back part of the base of the horns, intercepting a large sinus immediately over the middle of the cranial cavity, and from a third and larger one be- hind. The sphenoidal sinuses are of a large ; Slight differences in the developm
