CHANGES IN HUMAN CEREBELLUM WITH AGE 



11 



in females than in males. From his table I have arranged table 

 7, which shows the variations in both absolute and relative 

 weights in both sexes of different statures for the three decades 

 from twenty to fifty years— the most active period of adult life 

 when any differences due to sex or stature should be most evi- 

 dent, if present at all. 



TABLE 7 



The weight of the cerebellum according to age, sex, and stature. Based on Marshall's 



tables 



An examination of the table shows that his conclusion is open 

 to question. The percentage weights of the cerebellum for fe- 

 males are not uniformly higher than for males — to be exact, they 

 are higher in five groups out of nine in the table; in three groups 

 the values for males are higher, and in one group the values for 

 the sexes are the same. Under such conditions, the fact that the 

 average percentage weight of the cerebellum is very slightly 

 higher for females than for males can hardly be regarded in itself 

 as significant.
