membrane, and thus forming an appearance of a hollow ganglion. 



2. Pathetic nerve to the superior oblique muscle. 



3. First trunk of the fifth ; it passes close to the olfactory nerve, and appears to 



be connected with this, and gives filaments to the Schneiderian membrane ; 

 it meets its fellow on the floor of the nose, and then gives off a large branch 

 to the exterior of the upper jaw near the beak, and another to divide on the 

 palate, and send branches through perforations- in the bone to the membrane 

 covering the beak. 



4. Second trunk of the fifth, giving branches to the posterior part of the beak and 



palate.
