points s^inpathetic ganglion cells are to be found. When formed, the 

 ramus is a mixed nerve containing some fine medullated viscero- 

 sensory fibers from the palatine VII, some coarser medullated fibers 

 of the cutaneous type from the maxillary V, and likewise non-medul- 

 lated sympathetic fibers. The distribution of the medullated fibers 

 of this ramus (Plate 4, figs. 9-11) is along the median side of the 

 glandular gustatory strip (Plate 4, fig. 9, gm. gus. I.), which begins at 

 the angle of the mouth and extends to the anterior end of the upper 

 jaw. Posterior to the distribution of this ramus the glandular band 

 is narrower and is innervated wholly from the ramus lateralis (Figs. 

 10, 11) ; here however, it broadens. By the narrowing of the jaw the 

 two rami (r. lateralis and r. intermedins) are brought closer together, 

 until finally their terminal branches mingle (Plates 2, 3, figs. 4, 6; 

 Plate 4, fig. 9). 



(c) Ramus lateralis {pal. I.). This, like the preceding, is a mixed 

 ramus; but contains a larger proportion of cutaneous fibers. These 

 are drawn off from the maxillary ramus at the anastomoses indicated 

 in the plotting and dissection {an'stm. pal. I.). In the dissection 

 (Plate 3, fig. 7) these anastomoses of the intermediate and lateral 

 palatine branches with maxillary V are effected at the same point. 

 The ramus lateralis passes cephalad along the median side of the 

 maxillary bone and innervates taste buds and general epithelial sur- 

 faces (Plate 4, fig. 10). As described above, it has a terminal area of 

 distribution which is common to it and to the intermediate ramus. 



The relation between ner\'es V and VII, described here as the infra- 

 orbital plexus, may be taken as representative of the group. About 

 the only constant feature in the complex, however, is the palatine 

 ganglion or the point corresponding to it. It is believed that this 

 junction of V and VII would always disclose a ganglion if examined 

 microscopically, and the apparent importance of this ganglion as a 

 structural feature in Hatteria (Osawa, '98, p. 603, fig. 45) may be due 

 to, the fact that the cells are clustered instead of being scattered along 

 the nerve. The latter condition is probably due to the position of 

 the nerve, compressed as it is against the floor of the orbit. There is 

 seen to be some evidence, from the character of the fibers in these 

 anastomosing branches, to justify the acceptance, in a general way, 

 of Fischer's ('52, p. 138, 139) distinction between a posterior and an 

 anterior anastomosis, the posterior being a "sling" of the sympathetic 

 system, while the anterior is a mixture of fibers from V and VII for 

 distribution. Fischer did not recognize the sympathetic ganglia 

 present in this region, but based his view on the proximity of the
