Text: Certain conditions of sound produce undulatory effects and other conditions quite the opposite. In organ pipes of a certain caliber very sensitive waves occur at intervals according to the character of the sound. However, on combining a number of brass tube resonators, of nine or more in number, the induction of certain chords produces high vortex action in the air in the tubes. This also caused Keely considerable difficulty when he was using his Generator, for the reversions would cause vortex action in his resonator tubes and repeatedly blew the resonator caps off, destroying the adjustments in his machine. "In open atmosphere tuning forks produce alternate condensation and rarefaction of the air, but when a fork is placed in a tube and adjusted to thirds of the mass chord of the tube, a very different action takes place. Vibrators must be accurately adjusted to get such results; they cannot be set promiscuously in tubes and produce vortex phenomena." All corpuscular action in Nature is vortex motion. Progressive molecular and intermolecular disintegration of water invariably results in vortex motion of the highest order, but only peripheral. This results whether induced sympathetically or otherwise.
