A view of the distribution of the Glosso-Pharyngeal 

 Pneumogastric and Spinal Accessory Nerves, or the 

 Eighth pair: 1, the inferior maxillary nerve; 2, the 

 gustatory nerve; 3, the chorda tympani; 4, the auri- 

 cular nerve; 5, its communication with the portio 

 dura ; 6, the facial nerve coming out of the stylo- 

 mastoid foramen ; 7, the glosso-pharyngeal nerve ; 8, 

 branches to the stylo-pharyngeus muscle ; 9, the pha- 

 ryngeal branch of the pneumogastric nerve descend- 

 ing to form the pharyngeal plexus; 10, branches of 

 the glosso-pharyngeal to the pharyngeal plexus ; 11, 

 the pneumogastric nerve ; 12, the pharyngeal plexus ; 

 13, the superior laryngeal branch ; 14, branches to 

 the pharyngeal plexus ; 15, 15, communication of the 

 superior and inferior laryngeal nerves; 16, cardiac 

 branches ; 17, cardiac branches from the right pneu- 

 mogastric nerve; 18, the left cardiac ganglion and 

 plexus ; 19, the recurrent or inferior laryngeal nerve ; 

 20, branches sent from the curve of the recurrent 

 nerve to the pulmonary plexus ; 21. the anterior pul- 

 monary plexus; 22, 22, the oesophageal plexus.
