The day of si^routing and the mimber are tabulated iu Table VII, iio 

 acceleration is seen iu the hradiated seed. 



On Nov. 30, the writer carefnlly lifted ont 2 or 3 nnspronted seedlings 

 for examination and observed that they were similar to those in Experiment 

 X. In 20 H- and 30 H-plauts, only exceptionally stout ones sproiited (3 and 1 

 iu nnmbar). On April 2, 1918, scarcely auj' of the 20 H- and 30 H- plants 

 existed aud bj- the eud of April all had died. 



Ouly 10 H-plants develoj^wd together with the controls, but their growth 

 "was inferior to that of the latter. PqAstrillus abramvß also attacked these 

 ])lautä aud damaged them \erj much, but seeds were obtained from them (see 

 Figs. 11 aud 12 Plate Xn). 



The day of bloom h tabulated iu Table WH, wliich shows retardation 

 of the flowering time in 10 H-plauts, if compared with the controls.
