Other workers have noted the presence of other fibers than 

 those of fila olfactoria and the n. terminalis in the region occu- 

 pied by the nervns terminahs. These nerve rami have been 

 found in these preparations and come from two main rami of 

 V, viz., the ophthahnic division sending the ethmoidal nerve 

 into the anterior dorsal part of the nose (fig. 1) and the maxillary 

 division sending the nasopalatine onto the septum by way of 

 the sphenopalatine nerve and ganglion. The septal branches 

 from this latter source are numerous and conspicuous in this 

 series of sections (fig. 1). Some of the most posterior fibers 

 represented are deeply impregnated and seem to end in the 

 cancellated bone which apparently takes the place of ethmoidal 

 and sphenoidal sinuses at this age. Farther rostrally (fig. 1) 

 other rami pass dorsad from the main sphenopalatine nerve as 

 it takes its course toward the foramen incisivum. 



A peculiarly different nodal point marked A (fig. 2) in the 

 anastomosis of nerve rami attracted attention in studying the 

 sections, and on closer study seems to offer a possible posterior 

 sympathetic connection with the sphenopalatine ganglion. 

 When traced dorsally from this point it leads undiminished in 

 size into the bifurcating ventral end of the main large posterior 

 emerging ramus of the nervus terminalis as it issues from the 

 cribriform plate (figs. 1, 2). Here there is blackening in the 

 preparation and it can not be determined what disposition is 

 made of the fibers in the main posterior ramus of the nervus 

 terminalis which is composed of two or three bundles in its 

 course through the cribriform plate. Examination of the 

 other side and of the other series in my possession does not 

 clarify the matter, though this ramus seems constant in position 

 and larger than the other branches of the n. terminalis in the 

 cribriform plate and made up of two or three bundles. There 

 are about thirty or forty fibers in the connecting nerve which 

 measures 35 microns in diameter in the part of its course so far 

 described. Traced ventrally some distance beyond point A 

 it measures 25 microns and when carefully examined shows 

 fibers from three rami of the nasopalatine entering it. One
