supposed to produce two kinds of gametes, were used. With regard to the ratio 
and the area covered by the spots the nature of the individual was determined 
by taking the mean of the varying values obtained from six different flowers from 
the flowering axis. This procedure was unnecessary in the case of the colour, 
as the individual flowers on the same axis did not differ from one another per- 
ceptibly. 
As a record the fraternal correlation table for spotting is herewith given :

The parental correlations given above differ somewhat from those given in 
an earlier part of the paper owing to the fact that the mean of the character, as 
it occurred in the six flowers, was taken instead of using the individual flowers 
of the plant.
