106 AVES. 



8. Superior branch of the sympathetic passing from the superior ganglion ; it 



accompanies a large artery to the orbit, and is continued forward to 

 communicate with the second trunk of the fifth, and give filaments about . 

 the lachrymal gland. In the pelican, the branch proceeding to the 

 lachrymal gland appears to be derived rather from the second trunk of 

 the fifth, after this has received the branch of the sympathetic. 



9. Inferior branch from the superior ganglion of the sympathetic, passing at 



the base of the skull with the internal carotid artery ; it receives a branch 3, 

 from the hard portion of the seventh, and then goes forward, and sends 

 one branch into the orbit to Harder's gland, and communicates with the 

 first trunk of the fifth ; it sends another to the posterior part of the palate 

 and nose, and to communicate with the second trunk of the fifth.

THE SYMPATHETIC NERVE OF THE SWAN. 



(CYGNUS OLOR.) 



1. PROLONGATION of the sympathetic; after leaving the canal of the vertebral 



artery it communicates with the ninth, and then with the superior ganglion 

 which lies between, and is connected with the trunk of the par vagum and 

 the glosso-pharyngeal, at their exit from their osseous canals, and is placed 

 partly upon the latter nerve. 



2. Superior branch of the superior ganglion of the sympathetic ; it passes with 



a large artery to the orbit, and communicates with the second and third 

 trunks of the fifth, and with the hard portion of the seventh ; it gives a 

 branch to the lachrymal gland and conjunctive membrane; it sends one 

 branch beneath the slender bone of the tympanum to join the inferior 

 branch 3, close to the glosso-pharyngeal nerve.
