206 MAMMALIA. 



municating with the buccal and the second trunk of the fifth, and giving 

 branches to the muscles of the face. 



7. Inferior branch of the hard portion, communicating with the buccal and the 



rnylo-hyoideal nerve of the inferior dental, then passing towards the chin, 

 communicating with the inferior maxillary nerve after this has emerged from 

 its foramen, and giving branches to the muscles of, the face and lower lip. 

 Branches pass backwards from this, and the preceding branch 6, to commu- 

 nicate with others from the first cervical nerve distributed on the cutaneous 

 muscle. 



8. Supra-orbital nerve giving branches to the upper eyelid and the integuments of 



the forehead. Another branch is given off by the first trunk of the fifth, 

 which communicates with the temporal branch of the malar, and is then 

 given to the lachrymal gland, the conjunctive membrane, and the outer 

 portion of the upper eyelid. 



9. Temporal branch of the malar proceeding from the second trunk of the fifth ; it 



gives a branch to communicate with one of the first trunk of the fifth for the 

 lachrymal gland, and then passes out at the exterior part of the orbit, com- 

 municates with a branch of the hard portion, and is distributed on the cuta- 

 neous muscle and skin of the temple. 



10. Malar branch of the malar nerve arising with the temporal ; it communicates 



with a branch of the hard portion, and is then given to the skin of the face 

 and the lower eyelid. 



11. Continuation of the second trunk of the fifth to terminate on the upper lip and 



nostril ; this and all the other branches of the fifth in the face, communicate 

 freely with the hard portion. 



12. Auricular or superficial temporal branch of the third trunk of the fifth, giving 



branches to the skin of the ear and sending small branches forward to the 

 skin and cutaneous muscle of the face. 



13. Buccal nerve of the third trunk of the fifth, communicating with branches of 



the hard portion, and terminating on the buccinator muscle and skin of the 

 face.
