    due to the alternate approximation and separation of the plumbago + metal.

  1. Mercury might be substituted for the metal ­ as in Fig 3.

  2. Metallic holder h Fig 4 carrying plumbago pencil P may be vibrated in mercury + salt-and- water as in Fig 4.

    Undulations would be caused by the vibration of the metal h in the salt + water S; by the motion of the plumbago P in the mercury M; and by the alternate approximation + separation of the two good conductors h and M. Surely the amplitude of the electrical undulations would
