Fic. 3. Dimensions of the kidneys of males in relation to age. 
In females there is also an increase in size up to the age of 
30 and a very slow diminution up to the age of 80, with a 
secondary increase beyond that time. 
SUMMARY 
Briefly, my findings may be summarized as follows: 
1. The kidneys were in general at higher levels in males than 
in females. 
2. The variability of the horizontal planes of both kidneys 
was greater in males than in females.
