It will be as well to put together the frequency distributions of the capsules as we 
have done in the case of the trees:—

These distributions appear to be uniform although asymmetrical, and they give 
no obvious sign of a mixture. The mode is 10 for the Chilterns series and 8 for the 
Quantocks series, while the Shirley poppies give 12 for Chelsea and 13 for Hampden. 
It remains to tabulate the several results obtained for variation. These are 
given in the following table. We see at once that the general effect of 'freighting 
the capsules with the number of j^airs on the plant has the effect of increasing the 
mean and reducing the variability ; in other words, the plants with most capsules on 
and leading to most pairs, are those with the greatest number of stigmatic bands. 
We have some evidence accordingly that the most vigorous jDlants exhibit most 
bands on the capsules ;—
