TABLE 3 
Giving the corrected final average diameters of the nerve cells and their nuclei of the 
lamina pyramidalis and the lamina ganglionaris measured on the frontal and the 
horizontal sections of the albino rat brain. The average values of the two for 
each brain weight group are also given. The correction-coefficient for each brain 
weight group was taken from previous papers (Sugita, ’17 a, ?18b). F = the 
frontal section. H = the horizontal section.
