THE THREE CONDITIONS OF THE SEED 27 



TABLE B. SWELLING RATIOS OF SEEDS (HOFFMANN AND NOBBE). 



Swelling ratios of seeds adapted from the results obtained by Hoffmann and Nobbe, 

 and given in the latter's Handbuch der Samenkunde, p. 119, etc. (The weight of the 

 resting seed is here taken as i , as in the previous table. ) 



Note. According to Siewert, quoted on p. 120, the Lupines (Lupimts) have a 

 swelling ratio of 2*00 to 2*30. 



With regard to Table B, it is to be observed that the 

 original swelling results were stated as percentages of the 

 weight of the resting seed. These have been converted into 

 the ratios employed for my own results in Table A, where the 

 shrinking and swelling processes are combined in one simple 

 formula, the resting seed being taken as i. To have treated
