  1. Stanley's Autographic style will certainly succeed if we can only obtain a good enough conducting ink. Surely some solution can be found which will leave deposits of pure metal upon evaporation. "Bronze inks" containing metallic powder mechanically suspended do not seem to do, unless indeed the metal could be suspended in a fluid that is itself a good conductor.

  2. Plumbago Dip Will not a solid conductor of high resistance vibrated in a fluid of high resistance produce undulations of greater amplitude than if one of the two were a good conductor. Vibrate plumbago P in saturated solution of salt S.

  3. If in addition a piece of metal (in Fig 2) is placed in the salt + water, just under the pencil-point P, will there not be an additional effect
