bundle of fibers passes caudad of the sulcus olfactorius. Fig. 

 32 shows a reconstruction from nine horizontal Golgi sections 

 drawn with the aid of a camera lucida. The same essential 

 facts are shown by a number of other Golgi preparations of fishes 

 75 mm. long which belong to the same lot of fishes previously 

 mentioned as showing the nervus terminalis favorably. On the 



Fig. 32. Reconstruction from ten camera lucida drawings of consecutive sec- 

 tions of Golgi preparations of young Amia 75 mm. long. Shows the course of the 

 fibers following the internal carotid artery from the optic chiasm to the region of 

 the nervus terminalis. Arteries indicated in broken lines. The numbers indicate 

 the section from which parts were taken. X 25. 



left side, which is more fully impregnated (fig. 32), a bundle of 

 fibers follows the main branch of the internal carotid artery from 

 the region of the optic chiasm to the region of the nervus termin- 

 alis. The arteries are plainly visible in the preparations and are 

 shown by broken lines in the figure. The main bundle of fibers
