    about the same as in exp. 10­perhaps weaker.
  2. Three cells upon the secondary circuit (Fig 6) and one cell on the primary. Poles of MM' opposed. Sound much weaker than in Exp.11­about the same intensity as that heard in Exp. 5 ­ perhaps weaker.

  3. Three cells upon the primary circuit (Fig 6) and one upon the secondary. Poles MM' opposed. Loud sound. Louder than in any of the preceding experiments.

  4. Three cells upon the primary circuit­and no battery upon the secondary circuit. Sound at R or S (Fig 6 ) louder than in Exp. 13.

  5. Electro magnet M' had at least six times the resistance of M. M=1/2 ohm. M'=3 ohms (approx.) M' was placed in primary circuit and M in the secondary circuit. Arrangements otherwise as in Exp. 14. Sound at S (Fig 6) as loud as in (14) if not louder.
