    Results not so satisfactory as with wire.

  1. Tried the same experiment with about No 25 platinum wire. Slightly louder sound. In both these cases the vibration of the Receiver was barely visible.

  2. Tried copper wires of various sizes in place of platinum. Very much improved result. Wire No 20 resulted in a vibration of R so great as to strike the face of the magnet M.
    Wire No 16 gave as good if not better results. I could not test these comparitively as in both cases R struck the face of the magnet.

  3. R (Fig 6) was brought into the same room with T + T' so as to observe closely the effect of any variation in the vibration.
    Tried the effect of placing the wires WW' nearer + further apart + immersing them deeper.
