transferred to his garden, the result was as 430 to 332, the 

 weight of seed being therefore nearly 4 to 3. Lastly, of 

 plants covered by a net, six short-styled plants bore about 

 50 seeds, while 18 long-styled plants bore none at all. 



From these results, Mr. Darwin wrote, " we may safely 

 conclude that the short-styled form is more productive than 

 the long-styled form. . . . Consequently my anticipation that 

 the [long-styled form] would prove to be more feminine in 

 nature, is exactly the reverse of the truth." * We shall 

 see, however, that his surmise was probably, to some extent, 

 right, nevertheless. 



Mr. Darwin and Mr. Scott have recorded a great number 

 of experiments in ci'ossiug heterostyled plants, and the 

 following tables, constructed from details given by those 

 authors, show to what extent the plants named were benefited 

 by crossing either way.
