of the upper jaw, some of which communicate with others from the second 

 trunk. 



3. Second trunk of the fifth, giving a large branch to the upper eyelid, and 



branches to the palate, then passing at the exterior margin of the upper jaw, 

 and giving off numerous filaments to the superior surface of this part. 



4. Third trunk of the fifth, giving branches to the muscles of the jaw, and sending 



off the large branch, 5 ; it then passes within the jaw, distributing filaments 

 through perforations to terminate on the membrane covering the exterior of 

 this part ; at some distance from the beak it gives off a very large branch, 

 which is still continued within the jaw, but near the beak it passes through a 

 foramen, and divides into two branches to terminate on the mylo-hyoideal 

 muscle. 



5. Large branch of the third trunk of the fifth, giving off numerous branches, 



which divide into two planes, one to terminate on the mylo-hyoideal muscle 

 and the membrane lining the fauces, the other on this muscle and the skin. 



6. Sixth nerve, giving a branch to the abducent muscle arid that of the nictitating 



membrane. 



7. Hard portion of the seventh ; it gives a branch to the digastric muscle, and 



then becomes connected with several cervical nerves, which terminate on the 

 skin and cutaneous muscle, and communicate with branches of the conjoined 

 glosso-pharyngeal, par vagum, and ninth. 



8. Glosso-pharyngeal nerve, on which the ganglion of the sympathetic is situated : 



it becomes united with the trunk of the par vagum, and then divides into 

 numerous branches for the muscles of the fauces, the pharynx, and trachea, a 

 larger one accompanying the long muscle, resembling the genio-hyoideal or 

 hyo-glossal, as far as the beak ; many filaments communicate with branches 

 of the conjoined hard portion of the seventh and spinal nerves. 



9. Trunk of the par vagum ; it becomes united with the glosso-pharyngeal and 



ninth, and sends off a large branch to join the one proceeding from its 

 previous union with the glosso-pharyngeal ; it sends off another large branch 

 to join this union ; it then receives a branch of the second cervical nerve, 

 passes down the neck, and gives the recurrent branches to the larynx and
