    Foil Experiments Platinum foil P. Copper wires cc'.

  1. The platinum foil mentioned in Exp.6 proved too heavy. I happened to moisten it slightly with salt and water before presenting it to the wires cc' and at once a very peculiar noise proceeded loudly from the Receiver R.
    It was like the grinding of knives somewhat. This same noise has been alluded to before at page 33 (Exp. 6.).

  2. Platinum foil used in exp.7 was supported by two copper wires as in Fig 4 - only that the Instrument R was not placed in the circuit. In this case there was no spark when contact was broken.
  3. Automatic Transmitter & foil

  4. Experiments made with Automatic Transmitter arranged as on page 52. The platinum foil used in experiment 5 page 69 was employed with the Automatic Transmitter. P platinum foil; p' platinum wire
