roideal muscle, and terminates on the membrane of the glottis, epiglottis, and 

 the superior part of the larynx ; it communicates with the recurrent nerve by 

 a finer and a larger branch ; the finer communicates with the branches of the 

 recurrent passing to the posterior crico-arytenoid muscle ; the larger joins a 

 branch of the recurrent, and forms a broad and thick expansion not much 

 unlike a ganglion, which terminates in branches on the lateral crico-arytenoid 

 and the thyro-arytenoid muscles ; the rest of the recurrent gives filaments to 

 the posterior crico-arytenoid, and sends a branch behind this muscle to 

 terminate in the transverse and oblique arytenoid muscles. On the left side 

 the nerves were much smaller. 



14. Ninth nerve sending a branch to join one of those proceeding from the sub- 



occipital to the sterno-hyoid and sterno-thyroid muscles. 



15. A branch of the first cervical nerve to the skin of the ear. 



16. Accessory nerve.

1. Third nerve. 



2. First trunk of the fifth. 



3. A nerve proceeding from one branch of the first trunk placed behind the sixth, 



the other from the beginning of the second trunk in a spot at which a branch 

 of the sympathetic is received ; it is then joined by a branch from the third, 

 and passes to the inferior oblique muscle of the eye. 



4. Second trunk of the fifth. 



5. Malar and temporal branches arising separately from the second trunk of the 



fifth.
