NERVUS TERMINALIS: MAMMALS 11 



Numerous ganglionic masses of various sizes are found. One 

 group of relatively large size located near the most caudad bundle 

 of the vomeronasal nerve a short distance from where the latter 

 leaves the accessory olfactory bulb is regarded as the ganglion 

 terminale of authors. These groups of ganglion cells present the 

 appearance of small sympathetic ganglia, and the authors state 

 that the nerve fibers have more the appearance of sympathetic 

 and preganglionic fibers than of neuraxes and dendrites of sen- 

 sory neurones. A comparison of these cells with the cells of the 

 Gasserian ganglion of the same animals revealed. the fact that 

 the terminalis cells are of smaller size. 



Distribution of terminalis fibers to blood-vessels and septal 

 mucosa was considered probable from the observations, but the 

 authors hesitated to assert such distribution because of the com- 

 mingling of fibers from the trigeminus with those of the nervus 

 terminalis. . 



Johnston ('14) describes the central relations of the terminalis 

 in the adult human, in the horse, porpoise, and the sheep. Nu- 

 merous rootlets were found in some, especially in the horse, while 

 in other forms only two or three are enumerated. In the horse, 

 a large, compact ganglion is described. In the other mammals 

 the ganglionic masses are described as being smaller but more 

 numerous, and more or less scattered along that portion of the 

 nerve which it was possible to examine. 



Brookover ('14) independently of Johnston discovered the cen- 

 tral portion of the nerve in the brain of the adult human, and 

 reached substantially the same conclusions as to central connec- 

 tions as did Johnston, namely, that its intracranial course lies 

 over the middle of the gyrus rectus and appears to enter the 

 brain substance in the region of the medial olfactory striae. 



Both central and peripheral distribution in the human fetus 

 is described by McCotter ('15). He indicates the peripheral 

 course in the nasal mucosa, where it resembles in general the 

 conditions found by Huber and Guild in the rabbit. Centrally 

 the majority of the fibers form a single strand. 



The latest paper which has come to notice has appeared since 

 the greater part of the observations recorded in the present ar-
