the former. The frequencies and constants for total ovules per ovary are con- 
veniently tabled here for a later problem. 
For purposes of comparison we may now take the differences between the three 
series. We use : 
B — A, or the constant for the developing ovules minus the constant for the 
eliminated ovaries. 
C — B, or the constant for the matured fruits minus the constant for those in 
early stages of development. 
C — A, or the constant for the matured fruits minus the constant for the elimi- 
nated ovaries. 
The three comparisons are made in Table IV.
