In my hands and in those of Professor Farmer the germination (in 

 earth) of this 1895 sample was nil. The electrical response was 

 throughout small and irregular. A further test of germination made 

 on moist flannel in the incubator at 25° gave 40 per cent, as the pro- 

 portion of seeds exhibiting any sign of activity. 



The second series of this table gave a very striking and satisfactory 

 result. Of the ten seeds all but the seventh had given clear electrical 

 signs. They were planted in two regular rows and left undisturbed in 

 a greenhouse for one month. At the end of this time the box con- 

 tained two rows of nine vigorous plants with a gap opposite the 

 number 7.
