70 AMPHIBIA. 



6. Hard portion of the seventh; it communicates with the ganglion of the 



sympathetic, and then passes through the digastric muscle, to which it gives 

 a branch ; it communicates with the first spinal nerve, and terminates on 

 the costa-maxillary muscle. 



7. Glosso-pharyngeal nerve ; it passes to the ganglion of the sympathetic. 



8. Trunk of the par vagum ; it communicates with the sympathetic, and then 



with a branch that appears to be the continuation of the glosso-pharyngeal 

 from the ganglion of the sympathetic ; it sends a branch to communicate 

 with the ninth to pass to the muscles, &c., of the fauces ; and is then 

 continued downwards close to the trachea in company with each jugular 

 vein ; on the left side it also accompanies the carotid artery, and from this 

 a small vessel also ascends with the right trunk ; it sends filaments on the 

 large vessels towards the heart, and others behind each aorta similar to the 

 recurrent nerves, to be distributed on the trachea and oesophagus; each 

 trunk, for a short space, accompanies its corresponding pulmonary artery : a 

 little above the liver it passes in front of the superior part of the lungs, and 

 proceeds a short distance, where it is joined by its fellow to form a single 

 nerve ; this is contiaued downwards under a thick membrane on the liver, 

 and appears to give filaments to this viscus, the lungs, and oesophagus ; 

 about the termination of the liver it sends a large branch, which has com- 

 municated freely with branches of the sympathetic, to the left surface of the 

 stomach, this gives filaments to the lowest part of the lungs, and terminates 

 on the stomach. The right division, or the continuation of the nerve itself, 

 having communicated several times with the left division and filaments from 

 the plexus of the sympathetic, is continued a short way on the membrane 

 connecting the viscera ; it passes on the right surface of the stomach, distri- 

 buting branches to this viscus, and terminates on the beginning of the 

 intestine, reaching as far as the pancreas. 



9. A nerve from the ganglion of the sympathetic; it appears to be the conti- 



nuation of the glosso-pharyngeal after its junction with the ganglion; it 

 communicates with the ninth after its connexion with a branch of the trunk 

 of the par vagum, and terminates on the glottis and muscles attached to the 

 anterior point of the jaw for drawing forward the trachea.
