There is clearly a decrease in asymmetry from A to B and again from B 
to C. Owing to the smallness of our series the probable errors are high, but 
all the differences are over twice their probable errors, and the critical diiference 
C — A is four times its probable error. 
Diagram 7 shows graphically the frequency of the four chief asymmetry classes. 
Series B.

Intermediate. 
Series C. 
8165 ■9428 + 
Oldest. 
Series A. Youngest.

developing fruits for 1906. 
Problem 4. The frequency of the four types of ovaries with respect to the 
number of "odd" locules produced is shown for the three lengths of fruit in 
Table XXIV. and graphically (with percentage frequencies) in Diagram 8.
