NERVUS TERMINALIS IN AMIA

side in this position. Fig. 22 taken from a single sagittal section 

 of a Golgi preparation of a young Amia 75 mm. long shows the 

 relation of the nerve fibers to the artery at the anterior end of the 

 olfactory bulbs in the position where the internal carotid artery 

 is shown in fig. 19. It will be noted (fig. 22) that a fairly com- 

 pact bundle of five or six fibers accompanies the main artery. 

 From near it two fibers run dorsad along a blood vessel. The

Fig. 22. Sagittal section in the median plane from a Golgi preparation of a young 

 Amia about 75 mm. long. Shows a bundle of about five fibers following the course 

 of the internal carotid artery at the level of the anterior end of the olfactory bulbs. 

 The fibers become mingled with those of the olfactory nerve in the region of the 

 nervus terminalis, in the adjacent section. X 225. 



main bundle, which can be followed from posterior to the 

 sulcus olfactorius between olfactory bulb and hemisphere, 

 runs forward beyond the olfactory bulbs to be lost among the 

 fibers of the olfactory nerve. I have found fibers behaving like 

 those that run dorsad in fig. 22 in Cajal preparations accompany- 

 ing the small arteries among the bundles of the olfactory nerve in 

 adults at the level of the anterior part of fig. 19. Also, I have
