These relationships are forcibly shown in DIAGRAMS I and II. 
In both of these the intensity of the correlation is shown by the

length of the vertical lines. The broken ones extending above the 
zero bar measure positive values; the solid ones extending below 
the zero bar indicate negative coefficients. In DIAGRAM 1 the 
lengths of the lines are in terms of the correlation coefficients, 
Yoz; iN DIAGRAM 2 they are in terms of the ratio of the correlation 
to its probable error. In both, the large central figure represents 
the distribution of values for the whole material. This is analyzed 
into the Navy series, shown in the lower corner, and into all other 
series, shown in the upper right hand corner of the figures. The 
difference in the contribution of these two elements to the general 
series is very striking. 
IV. RECAPITULATION AND DISCUSSION 
In dwarf varieties of garden beans, Phaseolus vulgaris, there is 
but a slight relationship between the number of ovules per ovary 
and its capacity for maturing these ovules into seeds. So lax is 
this correlation that in working with only moderately large 
samples both positive and negative values of the iencrmr may 
be found in the same strain of material.
