palatine ramus (Plate 3, figs. 6, 7, pal.*), which passes through the 
foramen along with an artery and vein. The medullated fibers in this 
twig can not be followed farther in their distribution than the limits of 
this gustatory patch. 
Anterior to the orbit the viscero-sensory fibers are found in three 
rami, a median (pal. m.), an intermediate (pal. 2’m.), and a lateral 
(pal. 1.) ramus. All these rami carry a few coarser fibers not charac- 
teristic of the palatine proximal to its anastomoses. These are inter- 
preted as cutaneous sensory from V. 
(a) Ramus medialis. This is a continuation of the principal 
branch of the palatine (pal.*). At about the level of the ethmoidal 
ganglion (gn. eth.), or proximal to it, there is a division of the principal 
ramus (pal.*), which results in a branch passing laterad to help make 
up the intermediate ramus (Plates 2, 3, figs. 4, 6, 7), but the main 
branch is continued forward as the ramus medialis (pal. m.). In the 
dissection (Plate 3, fig. 7) this connection seems to be opposite the — 
ganglion instead of proximal toit. A very small group of sympathetic 
ganglion cells is found at this junction. Another, shorter, branch con- 
nects the median ramus with the ethmoidal ganglion, thus forming an 
anastomosis with the nasalis. It would appear that this anastomosis 
serves the purpose of bringing the ethmoidal ganglion into connection 
with all the other rami. This connection of the median ramus with 
the ethmoidal ganglion has already been described (p. 54). Distal 
_ to this point the median ramus continues an uninterrupted course to 
the tip of the snout to innervate the mucous membrane of the pre- 
maxillary region. This is a glandular region richly supplied with 
taste buds. It is produced by the median union of the lateral glandu- 
lar gustatory folds of the two sides. The course of the ramus medialis 
is just dorsal to the median edges of the palatine and vomer bones on 
either side of the interscapular nasal cartilage (Plate 4, figs. 8, 9). 
A short distance proximal to its distribution this ramus is joined be- 
neath the cartilage with its fellow of the opposite side by a median 
group of sympathetic ganglion cells (Plate 2, fig. 4, cl. gn. sy.). Distal 
to this the united mediales continue forward for some distance as a 
common median bundle; this bundle, however, splits again near the 
region of its distribution. 
(b) Ramus intermedius (pal. i’m.). This one of the terminal rami — 
of the palatine is formed by the union of two branches lying dorsad of 
the palatine bone, one from maxillary V, just before its entrance 
into the infraorbital foramen, the other from the ramus medialis at, 
or proximal to, the ethmoidal ganglion. At all three of these junction
