"When the proper impulse is given to induce the rotation with pure alternating corpuscular action, the condition of action become perpetual in their character, lasting long enough from that one impulse to wear out any machine denoting such action, and on the sympathetic stream eternally perpetual. The action of the neutral or focalizing centers represents molecular focalization and redistribution, not having any magnetism associated with them, but when the radiating arms of their centers are submitted to the triple compound vibratory force, representing their mass thirds, they become magnetic and consequently cease their rotation. Their rotation is induced by submitting them to three different orders of vibration, simultaneously giving the majority to the harmonic third."
