STUDIES IN SEEDS AND FRUITS 



Table showing the Effects of Drying in Ordinary Air 

 ON Leguminous Seeds Swollen for Germination. 



Note. — Variable seeds are those sometimes permeable, sometimes impermeable. 



NOTE 2, B (p. 29), 



A further proof of the mechanical nature of the swelling process of seeds 

 indicated by their ability to proceed with germination when dried, after 

 absorbing most or all of the water required for germination. 



(This proof was omitted on p, 29, and has been added since. It is 

 illustrated in the following table by the results of my experiments 

 on the influence of previous swelling and drying on the germinativfe' 

 capacity of different seeds.) ■ 



Knowing from the results of previous experiments, as given in the 

 table on p. 24, the swelling limit indicated by the maximum weight 

 attained before there were any external signs of germination, I was 

 able to conduct the experiments accordingly. In the case of the seeds 

 of Hura crepitans I repeated the experiment on the same seed, but the 

 seed in the instance of two experiments rotted.
