2. Hard portion of the seventh ; it communicates with the sympathetic, and sends 



branches to muscles analogous to the superior belly of the digastric and the 

 stylo-hyoideal, and communicates with a branch of the second cervical nerve, 

 to terminate on a cutaneous muscle connected with the external auditory 

 meatus and the posterior part of the face, and upper part of the neck ; after 

 having communicated with the second cervical nerve, it appears to pass down 

 and communicate with the third, and then with the fourth ; and although the 

 fourth communicates with the fifth, this with the next, and so on, it cannot 

 be determined that it is through the continuation of the hard portion of the 

 seventh. 



3. Glosso-pharyngeal nerve; it gives a branch to the pharynx and oesophagus, 



and muscles connected with the glottis, and then passes near the lower jaw 

 to the hyoid bone, gives a branch to the cerato-maxillary muscle, arising 

 from the lower jaw and surrounding the posterior part of the hyoid bone, and 

 then passes on the surface of the tongue, distributing filaments as far as the 

 tip, and communicating with branches of the nerve of the opposite side. 



4. Trunk of the par vagum. 



5. Ninth nerve ; it gives a branch to the hyo-laryngeal muscle, placed at the side 



of the trachea, and sends a large branch forward to give a branch to the 

 hyo-glossal and lingual muscles. 



6. Second cervical nerve, communicating with the hard portion of the seventh, 



and distributed on the cutaneous muscle and skin of the face.
