The maxillarybranch sends off a e subcutaneus malas, which combines with thefacial nerves to supply the inferior palpebral muscle, and spreadupon the hind part of the palpebral opening. There are five orsix antorbital branches which run forward between the maxillaryperiosteum and the superincumbent muscular and tegumentarylayer, emerging to spread upon the latter where it forms theupper lip or margin of the mouth, and also sending a recurrentbranch to the blow-hole. A large branch of the maxillary passes. with thequestion,figs. 234, 238, 241, v (vol. ii. Trigeminal nerve of Mole LXIII.

Thedental nerves are large from both maxillary and mandibulardivisions of the fifth: the gustatory branch is., relatively, small;and sends oif a filamentary 6 chorda tympani, which may be tracedto the trunk of the facial, and is connected, in its course, with thecarotid plexus of the sympathetic. In Ruminantia the first division of the ( fifth subdivides intofrontal and nasal: the latter supplies the upper part of theseptum and the superior turbinal, and sends a few branches tothe fore part of the nose, which meet these filaments reflectedfrom the second division of the fifth.
