correlations between the number of pods per inflorescence and all 
the characters of the pod are generally very low, it hardly seems 
worth the labor to reduce all the inflorescences to a standard 
frequency to avoid weighting. Designating the two characters of 
a pair which are being compared as “first” and ‘“‘second,’”’ and 
indicating them by one and two dashes respectively, we have the 
following relationships for consideration. 
Ovules of first locule and ovules of second locule, r:,°: 
Seeds of first locule and seeds of second locule, r,:,: 
Length of first pod and length of second pod, ry 
Length of first pod and ovules per locule in second pod, 7: 
Length of first pod and seeds per locule in second pod, 7)": 
Since the pods from each shrub must be. treated separately, 
this requires the preparation of 100 correlation tables, containing 
some hundreds or thousands of entries each. These have been 
carefully prepared and verified, and the means and standard 
deviations used in obtaining the correlation coefficients calculated 
anew for all the characters from the weighted frequencies. The 
tables and constants are too bulky for publication. The end results
