(Plate 3, fig. 7), the plotting from sections (Plates 2, 3, figs. 4, 6) 
being incomplete. Notwithstanding great variation in detail, the 
scheme of the plexus seemed to be in the main the following: — 
(1) Taking the main palatine as a point of departure, all the rami 
have their origin from VII at one point, or nearly so. This is where 
the palatine ganglion lies, as described by several authors. The 
palatine here is a ramus of considerable size and immediately gives off 
two main branches. These come off separately, but close together, 
in the plotted series (Plate 2, 3, figs. 4, 6). In fig. 7, Plate 3, they 
both arise from the ganglion. One of these (pal.') swings abruptly 
outward crossing ventral to the infraorbital ramus of V (Fig. 7). It 
innervates the mucous membrane and taste buds (gm. gus.) on the 
way. The other (pal.”) keeps a more median position until it crosses 
V to anastomose with the first (pal.!) to form the lateral branch of the 
palatine (pal.l.). (2) There is an anastomosis (an’stm. pal. l.) with 
VY, from near this juncture, and sections always show ganglion 
cells at this point (Fig. 4, cl. gn. sy.). (8) There are always two or 
three branches (Fig. 7, a, 8, y) which turn back to join V just distal 
to the infraorbital ganglion, and their appearance indicates a large 
proportion of non-medullated fibers. (4) Anterior to the orbit there 
are anastomoses (a) that connect the intermediate branch of the 
palatine with the maxillary nerve just before the latter passes into 
the maxillary bone (Plate 2, 3, figs. 4, 6 and 7, an’stm. pal.z’m), and 
| (b) that connect the median palatine ramus with ramus nasalis V | 
| through the ethmoidal ganglion. These anastomoses account for the 
| mixed character of the lateral and intermediate rami of palatine VII. 
Terminal twigs given off from the infraorbital plexus. Of more 
| importance than the exact form of the anastomoses are the twigs for 
terminal distribution given off from the branches making up this 
plexus. In all cases the main course of the principal branches is 
explained by an examination of the mucous membrane of the roof of 
the mouth. All the rami carry viscero-sensory fibers for the innerva- 
| tion of the taste buds. These sense organs are distributed within two 
restricted fields of the mucous membrane underlying the orbit, a 
small median area and alateral one. The median group of taste buds 
 \(Plate 5, fig. 12, gm. gus. m.) is much more limited than the lateral 
(roup. Here the buds are within a sensory-glandular patch little more 
than a millimeter in length (between sections 732 and 874), which lies 
w the pterygoid. The position is approximately indicated in the fig- 
ure of the skull by the foramen in the pterygoid bone (Plate 1, fig. 3, 
for. pi.). The innervation is from a twig (gm. gus.) of the median
