• In November, 1884 he [Keely] demonstrated successfully an experiment which he had worked out theoretically but which had failed on several previous attempts. Two persons took firmly hold of an "iron rod". One person stood on a circular sheet of metal, from which piano wire stretched to, and touched, a plate of glass, which in turn insulated a small globe. The description given, indicates the globe was centered axially on the iron rod. Another glass plate insulated the globe, presumably on the other hand. The globe rotated when both persons, took hold of the opposite ends of the iron rod, and rotation ceased when Keely, who was one of the operators, took hold of the other operator's left hand with his right hand. Keely stated the reason for this to be "The reception flows became independent of the circular chord of resonation set up mechanically. The power of rotation comes on the positive and power of negation breaks it up." He stated the reason the sphere revolved was because of the "receptive concussion of two forces, positive and negative, coming together, seeking their coincidents, producing rotation by harmonious waves, not by harmonious streams in this case." He stated the introductory settings were entirely different from those of the musical sphere and that sound waves had nothing whatever to do with rotation of the globe.

• March 22, 1885 he [Keely] wrote: "Details of the present engine are as perfect as possible for the first lead. It is in the form of a sphere about thirty inches in diameter and weighs 800 lbs."
• Under date of 5/20/1885 he writes of an experiment in which he attached a safety arrangement to his Liberator, and also his strongest resonator, and "within two minutes the shell (probably the musical sphere) attained a rotation of 1500 times per minute. I then retracted to the negative and brought it down to 150 revolutions per minute, when two of my safety shells and a vibratory indicator blew up, causing intermission." [HOW THE MUSICAL SPHERE ROTATES]
• 5/20/85 "After laboring six hours to set my safety process, the first operation of the Liberator tore the caps of the resonating tubes all to pieces. I replaced them with duplicates and set the Liberator on the low octaves, when everything worked to a charm. I followed up with great care the progressive chords to the tenth octave and liberated a score of times with the gun, yet no variation or intensification on the Liberator. I worked the Liberator continuously for 64 minutes on the revolving sphere when a second intensification took place, demolishing two safety shells and one vibratory indicator. I am unable to account for this. I then set up a position on the resonating wave plates in the forty resonating circuit and secured the best results I have ever yet secured. I believe I shall be able to obtain continuity of motion with perfect rotation." [MECHANICAL DEVICES FOR SAFETY]

My chief trouble is in chording up the masses of the different parts composing the negative centers in the inner one-third volume. This neutral center is only established free from influences of gravity when rotating at 100 revolutions per minute, with the vibratory circuit running at 100,000 per second.

1888

• He [Keely] announced in 1888 that he had discovered this "sympathetic vibration" to be associated both positively and negatively with the polar stream. [MASS VIBRATIONS]
• In 1888 he [Keely] announced that he had proved the uselessness of attempting to build an engine employing the ether as a motive power, such as we use in steam or electricity, stating that it could only be used as a medium for energy. This he later attempted to accomplish in his magnetic engine. [MECHANICAL INVENTIONS AND INSTRUMENTS]
• Previous to 1888 he [Keely] had tried in vain to construct an engine that could hold the ether in a "rotating circle of etheric force." At the end of that year he abandoned the idea of his "perfect engine" and thereafter devoted himself to researches. He was then furnished finely made instruments in place of the home made instruments he had heretofore used. Up to 1888 he had not been able to control reversions or obtain continuity of motion. For nearly fifteen years he had constructed engines of different models in attempting to control or use ether as we now use steam before he discovered this was impossible. In his magnetic engine he thereafter sought to use the ether merely as a medium for "sympathetic vibration associated with the polar stream positively and negatively."
