    touched with the finger or when S' was removed.
  1. Circuit aM'b-eM2f-a No battery Faint sound from M2 ­ weaker than that mentioned in experiment 3.
  2. Same arrangement but cd crossed making closed circuit cMdc. No sound audible from M2 when S was plucked.
  3. { Circuit cMd-eM2f-c. No battery    and
         Circuit g-d-M2b-h Two cells of Grove elements.
    Sound heard from M2 similar to that mentioned in experiment 6.
    4. dMc-fM2e-h the sound at M2 became very much weaker
  4. Circuit g-cMd-eM2f-h (as in experiment 1) Loud sound from M2. But upon changing the direction of the current by making circuit g-dMc-fM2e-h ­ the sound at M 2 became very much weaker.
  5. Wires d + c united to g; b + d united to e; + f to h. Sound at M2 slightly fainter than in exp.1. but louder than in any of the other cases. (see Figs 1 + 2)
  6. Wires a + d united to g; b + c united
