of the sound given and by a telephone is no measure of the energy of the current passing through it.
The following broken lines will serve to represent the maximum and minimum currents passed through the telephone in this experiment

Ever since this new method of varying the energy of an electrical circuit occurred to me, I have felt confident that it could be made available for telephonic communication; but the intermittent character of the current used seemed to forbid this. I have during the past week devoted a great deal of thought to this subject, and think that I have got several methods of eliminating the intermittent effects from the circuit.
The arrangement shown in the following diagram seems to me to be the more promising at the present time:
