From these bulbous enlargements (which, though covered in by the cerebrum, are separated from it by foot-stalks, as in the Shark, §. 453), are given off the small branches which pass down into the nose, (§. 506). Next to these are the optic nerves (2), which may be traced backwards to the optic ganglion, g. The third, fourth (4), and sixth pairs (6), are nerves of motion only, and are distributed to the muscles of the eye. The fifth pair is for the most part a nerve of sensation only. Before leaving the skull, it divides into three great branches; of which the first (5) passes into the orbit (or cavity in which the eye is lodged), endows the parts contained in it with sensibility, and then comes out beneath the eyebrow, to be distributed to the B B 2.
