TABLE SHOWING THE PROPORTIONAL WEIGHT OF THE SEED'S COVERINGS 

 (SEED-COAT RATIO) IN THE THREE CONDITIONS OF THE SEED, 

 THE LARGE, MOIST, PRE-RESTING SEED OF THE RIPE FRUIT, THE 

 RESTING SEED, AND THE SEED SWOLLEN FOR GERMINATION. 



(From the data given in this table the regime of the shrinking and swelling seed can 

 be readily constructed, as explained in the example given. P. = permeable ; I. = imper- 

 meable ; V. variable.)
