out its extent branches are given off, some of coarse fibers to the 

 mucous membrane, and others composed of finer fibers from the 

 sphenopalatine ganghon which pass into the glands of the sep- 

 tum. The septal glands are numerous in the region posterior to 

 the vomeronasal organ. Finally, reduced in size and composed 

 only of fibers of larger size, the nasopalatine nerve passes through 

 the incisive foramen to reach the roof of the mouth. 



e. Other branches. In addition to the fibers from the spheno- 

 palatine ganglion described above, there are several other small 

 nerves either arising or ending within it. One small nerve ex- 

 tends from the ganglion posteriorly along the medial side of the 

 semilunar ganglion (fig. 7) . Several other small bundles extend 

 from the sphenopalatine ganghon dorsally and laterally to join 

 the ophthalmic nerve. (These are not shown in the graph, fig. 

 7.) The origin, the direction or the endings of these nerves 

 could not be determined. 



Several small nerves take origin from the anterior part of the 

 sphenopalatine ganglion and pass dorsally along the medial wall 

 of the orbit. Some of these join the nasociliary nerve, and 

 through it finally terminate among the gland ducts of the an- 

 terior and inferior part of the lateral wall of the nasal cavity. 

 ■Others accompany a blood-vessel into the medial part of the 

 lacrimal gland, while one other joins a small branch of the maxil- 

 lary nerve which terminates in the nasolacrimal duct. 



Other branches from the anterior end of the ganglion join the 

 arteries in the neighborhood and accompany them in their 

 peripheral courses. 



f . The nerve supply of the palate. The nerve supply of the 

 palate was investigated to determine, if possible, the relationship 

 between the nerves of the taste-buds, the nerves to the palatal 

 glands, and the facial nerve. Although no positive conclusions 

 were reached, certain features are of interest and will be recorded 



here. 



From the ventral 'end of its bony canal the anterior palatine 

 nerve extends anteriorly, in company with a medium-sized ar- 

 tery, as far forward as the nasopalatine canal. Throughout its 

 entire extent it sends branches medially and laterally to supply
