than 7.5 //. Since there are in all 203,700 nerve fibers in the 

 ventral roots of the left spinal nerves and of these 80,747 are 

 small fibers, it appears that the small fibers constitute 39.64% 



TABLE III. 



Showing counts made in the different ventral roots in order to de- 

 termine the relation between the number of large fibers (7.5 n or more 

 in diameter), and the number of small fibers (less than 7.5 « in 

 diameter). 



Total 80747 



N'OTE — The numbers marked by a star "•■■ do not represent the fibers counted, 

 but were obtained by subtracting the small fibers ivhich were counted in these 

 fascicles from the entire number of fibers in the fascicle.
