"No condition of absolutely stable equilibrium exists in Nature. The chord of the mass changes, yet we must, through induction of resonance, learn to control the molecular forces. Keely claims to have solved this problem by the invention of a device - his "compound mechanical device" - which brings the chords of all masses within the conditions of a few simple acoustic tests.
