72 GERMINATION 



took them week by week before touching those which were 

 grown in the open ground. 



The first of these was one potted apex upwards. The 

 plumule was 4-inches above top of seed and carried four 

 leaves, besides four young leaves. The radicle and plumule, 

 at their junction, took a decided curve. 



The seed substance was not shrivelled like the last one 

 but proved to be black and almost totally decayed. One 

 half, however, showed that the coUar instead of merging 

 into a protuberance or swelling (i.e., cotyledons) continued 

 flat throughout the seed. The seedling was quit« healthy 

 and apparently required no further assistance from the
