heavier than 3.28 grams while three fruits are lighter. There is 
thus a remarkable agreement between the geometrical mean and 
the actual generation fruit average. 
There were four distinct series of F-2 plants grown. Each 
series was derived from a separate parent F-l plant or fruit. The 
following table shows the average fruit-weights of the plants of 
the F-2 series 15-11-2—II—I: 
15-11-2—II-I. Plant 1 = 2.56 grams. 
“ “ 2 = 2.48

“ “ 9 = 1.86 
“ “ 10 = 3.18 
“ “ 11 = 4.16 
“ “ 12 = 2.55 “ 
The average weight of fruit for the above series is 2.54 grams. 
The series 15-11-2—II—II, was composed of F-2 plants which
