So also with the torsional vibrations of plants, I find response depending on the quickness with which the vibration is effected.
In the first (A) the stimulus was applied by means of the spring-tapper, and in the second (B) by torsional vibration.
The handle, by which a torsional vibration is imparted to the wire, may be slipped over either electrode.
