"You see," he explained, "the principle on which this is based is that a mass of tempered steel may be impressed with and will retain magnetic fluxes varying in density and in sign in adjacent portions of itself—little deposits of magnetic impulse.
"When the telegraphone is attached to the telephone wire, the currents that affect the receiver also affect the coils of the telegraphone and the disturbance set up causes a deposit of magnetic impulse on the steel wire.
