seeds. The daj of sprouting is delayed pro^xirtioLial to the increase of dose, 

 i. e., one of the 80 H-plauts sprouted one day iu January '18, but the 150 H- 

 seeds did not sprout at all above the soil. But it was evidently saen even iu 

 their dead condition at the observation on April 2, 1918, that the 150 H-seeds 

 Lad germinated and developed to seedHngs, whose radicle reached 2-3 cm. under 

 the gi'oimd. 



Table XI. 



As Table XI shows, the day of bloom is delayed proportional to the 

 doses. Moreover, it is interesHug to note that tlie day of sprouting and 

 bloom is delayed rather more than iu the two former es]^)eriments. The 

 retardation of sprouting may Ix; due to the difference of stimulus; the seeds 

 having much water by steeping may have Ijccu more stimulated than the 

 air-dried ones. If the sprouthig is delayed, so will the gi'owth, and thus a 

 retardation of the time of bloom will naturally take place. 



Tlie relation l^etn-cen i^ercentage of sprouted seeds and the remainder at 

 the time of bloom is shown in Table XII, as well as the fullgi-owu plants.
