former accompanies the superior maxillary nerve, receives 
a bundle of fibres from it as in Menidza, and ultimately 
supplies pit organs in the region of the nose, as in Menidia 
and Gadus, and also the supposed vestige of the left 
supraorbital canal with its single sense organ (sup. ¢."). 
The latter after a very long course, during which it gave 
off no branches at all, was ultimately traced to sense 
organs 1, 2, 5 of the infraorbital canal. 
5. After giving off the R. buccalis the main trunk 
of the dorsal lateral line root is continued forwards as the 
R. ophthalmicus superficialis facialis, forming the 
remainder of the T. supraorbitalis (r. oph. sup. viz), and 
which is closely associated with the nerve of the same 
name from the trigeminus. It is connected at its origin 
with the Gasserian ganglion, situated below it. Its course 
and relations will be seen on reference to the chart, and it 
is mostly concerned with supplying the 5 sense organs of 
the supraorbital canal. 
6. Ramus palatinus facialis (pal.).—Arises intra- 
cranially from the geniculate ganglion proximal to the 
formation of the Truncus hyomandibularis. It remains 
within the skull until it reaches the region of the orbit. 
At first it passes forwards and downwards, very closely 
attached to the cranial sympathetic from section 536 to 
494, and ganglion cells really belonging to the latter have 
been described as belonging to the palatinus. Subse- 
quently the palatinus passes downwards, and enters the 
eye muscle canal. It leaves this canal in front and passes 
far in front of the brain straight across the orbit and 
above the superior maxillary v. nerve. In the. anterior 
region of the orbit, where it les over the roof. of the 
pharynx, it turns sharply downwards. During its course 
across the orbit it gives off branches to the terminal buds 
in the roof of the pharynx.
