city. This apparatus for moasurement is situated between 

 the water and the earth. 



5:o. The quantity of drawn water is proportional to 

 the intensity of the current, which is in inverse proportion 

 to the square of the distance between the point and the 

 meniscus. The water quantity in question depends, besides, 

 on the diameter of the tube, on its lenght and on the re- 

 sistance in the circuit. 



6:0. The drawn quantity is proportional to the time 

 during which the current is going, yet only within a certain 

 interval (3 minutes in preceeding experiments), depending 

 on the fact that the water, running down through its gra- 

 vity, is then equal to the drawn quantity. 



7:o. Solutions of salts seem to behave in the same 

 way, but the drawn quantity is less, under otherwise same 

 circumstances. 



§ 8. During the studies and experiments I have made^ 

 regarding the influenee of electricity, on growing plants *), 

 the same method has always been applied viz. över the fi- 

 eld an insulated wire-net, which has been united with one 

 pole of an electrical influenee machine, the other pole be- 

 ing conducted to the earth. When the positive pole was 

 united with the insulated wire-net, a current was going from 

 the net through the plants into the earth, when the nega- 

 tive pole was connected with the wire-net the current had 

 an opposite direction from the earth through the plants to 

 the wire-net. 



As the plants suck up their saps through capillary tu-
