Thus the town con<iitions of Cliel.sua and the potting at Oxford wore unfavour- 

 able to the development of many stigmatic bands, while at Crockham and 

 Enfield the soil or climate vvere more favourable than on the top of the Chiltern.s. 

 The alterations in variability are not so marked, but the potting in a specially 

 mixed soil while it lowered the mean seems to have increased the variability. 



We can deal with the influence of environment in a somevvhat different 

 nianner on the basis of the seed (a). We can compare what the weighted parents

* The Oxford poppies were grown in pots placed on gravel. If we adJ to the above another 45 pots 

 of seed (7) grown in pots placed upou a garden bed we find for the whole series of 967 capsiiles : 

 mean 10-87, S.D. = 3-001. This sliows the great influence of an even slight change of environment. 



t Chelsea I, the crop of 1899 from different seed gave on the basis of 1020 capsules a mean of 12-37 

 and a Standard deviation of 1-680, the equality of the variabilities is possibly only accidental. 



X These are the mean and Standard deviation of the selected parent Hampden plants, of which 

 I took all the seed from all capsules. A distinction must always be drawn betwcen plant mean and 

 capsule mean. 



§ These are the mean and Standard deviation of the selected 100 Enfield parent plants.
