Now this table contains a good deal of interest. Upwards of a thousand poppy 
plants were dealt with, involving the counting of the hands on more than ten thousand 
capsules, and the entry of more than a quarter of a million of pairs in the correlation 
tables. We see at once that the mean and variability of the Shirley poppy differ so 
widely from those of the wild poppy, that it is idle to group these species for these 
characters together. It is interesting to note, however, that both in the number of 
iDands and in the variability the Hampden poppies, whether wild or Shirley, stand at 
the top of their respective series. With regard to the wild poppy, I probably 
gathered from a wider area with a greater variety of environment than was the case in 
Series (ii.) or (iii. j. That mine were gathered from much poorer soil is evidenced by 
ni}^ plants having on an average only 6 capsules, while the Quantocks and southern 
Clultern poppies had about 10 cajDsules. The difference is possibly even greater than 
these numljers indicate, for I counted every bud I possibly could. The two Chiltern 
series do not differ much in the mean number of bands, but the difference of variabilitv 
is very significant. I should take it to be a veiy fair measure of the I’elative range 
of environment in the two cases. When we turn to the Shirley series the 
difference is almost too great for any comparison. While the Hampden series had 
some twenty-five capsules, on an average, to the plant, the Chelsea series numbered 
* The reader must bear in mind that this column gives the number of pairs of the symmetrical tables 
below, or tidce the number of independent pairs.
