About November 1884 Keely was conducting new researches in etheric vacuums. He says: "Working in a new lead I propose to show my introductory evolutions in proof of the negatization of an etheric substance to produce vacuums. Professor Rogers saw the operation inducing these etheric vacuums and pronounced the result wonderful." At that time he evolved vacuums of from one pound to fourteen pounds per square inch, and he stated further: "As soon as I combine all the positive and negative forces of etheric vibration in the triple vibratory sphere engine (his disintegrator) my machine will be perfect." During the course of his researches he demonstrated "etheric wave motion, concentration under vibratory concussion and negative vacuous tenuity." During the last part of his experiments along this line he succeeded in producing vacuums of from 30 inches to 57 inches of mercury in the ordinary barometer tubes used in measuring these vacuums, which would be utterly impossible by any mechanical means except genuine. Experimentally, these vacuums he produced are the strongest evidence that Keely actually discovered and which no one would believe because of the stock company fraud which was planned and put through by the stock speculators without his knowledge or consent. The very best vacuum that science, of Keely's day or this, can produce, is 17.99+ inches of mercury, in view of which his maximum vacuum of 57 inches can, or should be, appreciated as quite as marvelous an achievement alone, as the discovering of America or the invention of the cinematograph.
Keely states that through neutral focalization there are three different degrees of vacuum evolution, corresponding to the three fundamental forms of matter; 1) Molecular and intermolecular ruled by the enharmonic chord; 2) Atomic and interatomic ruled by the harmonic chord; and 3) Etheric and interetheric ruled by the dominant chord.
