As the graphs show the cells in the L. ganghonaris complete 

 their rapid growth between 10 and 20 days of age, while the 

 cells in the L. pyramidalis are a little slower. In this latter 



TABLE 48 



Giving the commuted number of nerve cells in the entire cerebral cortex, obtained on 

 the basis of the measurements given in this series of studies. The ratio of the 

 number of cells of each later group to that Group II (birth) is also given 



* As explained in (footnote 4), loc. cit. the actual number of cells contained 

 in the computed volume of the cortex should be N X L. F X W. D X T X 500, 

 but, for the convenience, l/lOO of N- X L. F X W. D. X T, or 1/50,000 of the 

 actual number of cells contained in the computed volume, was given here as 

 the computed number of cells in the cortex.
