manner. A number of wild plants had been trans- 

 planted during the previous autumn into a large bed 

 in my garden, and all were treated alike ; the result 



was

These figures give us the following proportions : 

 TABLE 4. 



The season was much more favourable this year than 

 the last ; the plants also now grew in good soil, instead 

 of in a shady wood or struggling with other plants in 

 the open field ; consequently the actual produce of 

 seed was considerably larger. Nevertheless we have 

 the same relative result; for the short-styled plants 

 produced more seed than the long-styled in nearly the

 standard of comparison, namely, the product of seeds 

 from an equal number of umbels, the excess is, as in 

 the former case, nearly as four to three. 



Looking to these trials made during two successive 

 years on a large number of plants, we may safely con- 

 clude that the short-styled form is more productive 

 than the long-styled form, and the same result holus
