1. GANGLION of the sympathetic nerve, situated near to and connected with the 



trunk of the par vagum. 



2. A branch of the sympathetic nerve passing some way in a canal at the base 



of the cranium, and forming a small ganglion with a branch of the second 



trunk of the fifth ; it sends filaments to the membrane covering the posterior 



part of the mouth and palate, one of which communicates again with the 



second trunk of the fifth before its termination ; the ganglion then sends 



another branch forward to form another ganglionic union with a branch of 



the second trunk of the fifth, and from this a branch is sent to the posterior 



part of the nose to ramify on the Sclmeiderian membrane ; other branches 



are given to the membrane covering the mouth and palate, and one passes 



forward and communicates again with a branch of the second trunk of the 



fifth, .and is distributed on the membrane covering the anterior part of the 



mouth and palate. It is worthy of remark, that the nerves distributed on 



the membrane of the mouth, palate, and nose, communicate so many times 



with branches of the second trunk of the fifth, and their connexion is so
