From the above it will be seen that the number of plants 

 grown from the ill-formed seed, from the light seed, from the 

 medium seed and from the heavy seed, that came to maturity 

 as fully developed, vigorous plants, was practically the same. 

 This is especially evident when we consider the fact that the 

 averages given above are based upon such a small original num- 

 ber as ten plants set out in the field. I am told that there were 

 as many surviving seedlings ready to be set out in the field 

 from the light and medium weights of seed as from the heavy 

 seed. On September 2 these plants had formed over twenty 

 capsules of seed apiece, were or just had been fully in flower and 

 were, in most cases, making vigorous laterals on which numerous 

 flower buds were forming.
