104 GERMINATION 



" October 10th : B still vigorous but growth at a stand- 

 still, as might be expected. 



" December 17th : Tallest blade of B, 5|-inches ; second^ 

 4-inches. Vigour slightly fallen off but this may be 

 due to cold weather ; A shown no sign of life since 

 September 14th." 



Here, I submit, is evidence that given a suitable electro- 

 lyte in and same measure of electrification of the soil a plant 

 would probably thrive upon a mere fraction of the water 

 ordinarily required. We must, of course, make allowance 

 for evaporation from a pot and take into consideration the 

 limitation of root depth, but the conditions were the same 

 for both A and B. 



In one respect the experiments were unsatisfactory. I 

 should have interposed a resistance in the circuit of B to 

 reduce the current strength nearly to that of the earth. 

 As it was B was over-stimulated.
