an intra-inflorescence correlation for number of seeds and for 
length of pod be sometime demonstrated for matured fruits of 
Cercis, it would indicate that in this species a somewhat lower 
proportion of 7, is due to a direct physiological relationship between 
the two characters than is indicated by the constants already 
calculated. 
5. THE HYPOTHESIS OF THE DIFFERENTIATION OF INDIVIDUALS 
If a sample of pods be made up of collections from a series of 
individuals, a (statistical) correlation will be found between two 
characters of the pod, say length and number of seeds, whether 
there is any physiological relationship or not, providing that the 
individuals are differentiated among themselves with respect to 
both of the characters in such a way that in the several individuals 
of the series both characters of the pair tend to fall above or below 
the means for all the individuals. Concretely, we understand for 
our present material that if, because of innate vigor or by reason 
of favorable environment, some individuals bore both larger pods 
and more seeds than the average, while other individuals with less 
innate vigor or with less favorable environment produced both 
smaller pods and fewer seeds than the average, then the correlation 
table prepared for the whole series of pods would show a sensible
