The cranial nerves are : (1) four pairs of sensory nerves carrying sensory impulses from the sense-organs to the heart, viz. the optic, auditory, olfactory, and gustatory nerves, and (2) six pairs of motor (or mixed nerves), *e.g.* three pairs of motor nerves for the eye (Motores oculorum, Pathetic and Abducentes) working the Levator Palpebræ and other muscles of the orbit; one pair of motor nerves for articulation (the Hypoglossal); one pair of motor nerves for the larynx (the Pneumo-gastric), and another pair connected with mammæ and (in the case of the male) the seminal duct. It is further stated that other motor or sensori-motor impulses are carried by some of these cranial nerves, viz. those which produce sighs and sobs, yawning, laughter, and hunger. Evidently some of the functions of the pneumogastric and the spinal accessory nerves are intended, as also of the phrenic and other nerves of the cervical plexus.
