NERVUS TERMINALIS IN MAN 135 



tion to other structures of the brain. This region seems to cor- 

 respond very well to the entrance of the nerve in other mammals, 

 viz., not very far lateral to the lamina terminalis. 



It will be interesting to note what relation, if any, the fibers 

 of the nervus terminalis bear to ^any other fibers of nerves pos- 

 terior that may enter the cranial cavity with the internal carotid, 

 for I believe it is conceded that nerves accompany the vessels 

 to the meninges. The internal carotid in man divides into an- 

 terior and middle cerebral arteries immediately over the most 

 posterior point to which we have traced the nervus terminalis. 

 The naso-ciliary branch of the ophthalmic ramus of the trigem- 

 inus nerve enters the cranial cavity lateral to the olfactory bulbs 

 to pass out anteriorly into the nasal mucosa. Our sections of 

 • this nerve in its intra-cranial course in the adult and in its proxi- 

 mal distribution in the nasal mucosa did not reveal any cells 

 that were like those of the nervus terminalis or that could be 

 called ganglion cells. We are not clear from our sections that 

 any branch is sent off from the intra-cranial course of the naso- 

 ciliary.
