I [..] accepted and held the Presidency of The Society of Arts and Sciences in New York for seven years for the sole purpose of giving to the world this new cosmogony based upon a two-way continuous, balanced universe to replace the one-way discontinuous, unbalanced universe which is presumably expanding to a heat death.

The full impact of Andrija's life, and his wide ranging intellect will probably not be understood until the young researchers of this day and age will take over his research, and finish it.

The atom is infinitely divisible.

Thus, either present elements are the true elements, or there is a probability of eventually obtaining some more high and general power of Nature, even than electricity; and which, at the same time, might reveal to us an entirely new grade of the elements of matter, now hidden from our view and almost from our suspicion.

A mysterious force exists in the vibrations of the ether, called sound, which science and invention have so far failed to utilize; but which, no doubt in the near future, will come under man's control, for driving the wheels of industry. Thought as Force.

The horizon of matter, which has been thought to rest over attenuated hydrogen, may extend to infinite reaches beyond, including stuffs or substances which have never been revealed to the senses. Beings fashioned of this substance might walk by our side unseen, nor cast a shadow in the noon-day sun.

There is a distinct advantage in having one section of scientific men beginning their work untrammelled by preconceived notions.

Tizeau found that the speed of light is increased in water which moves in the same direction as the light. This result must be due either to the motion of matter through the medium, or to the fact that moving matter carries the ether with it. The whole question of matter and motion as a medium is a vital one, and we shall hardly make any serious advance before experiment has found a new opening.

A knowledge of scientific theories seems to kill all knowledge of scientific facts.

Electricity is the result of three differentiated sympathetic flows, combining the celestial and terrestrial flows by an order of assimilation negatively attractive in its character. It is one of Nature's efforts to restore attractive differentiation. In analysing this triple union in its vibratory philosophy, I find the highest order of perfection in this assimilative action of Nature.

All the forces of nature, writes Keely, proceed from the one governing force; the source of all life, of all energy. These sympathetic flows, or streams of force, each consists of three currents, harmonic, enharmonic, and dominant; this classification governing all orders of positive and negative radiation. The sympathetic flow called Animal Magnetism is the transmissive link of sympathy in the fourth, or interatomic, subdivision of matter.

In the conception of any machine heretofore constructed, the medium for inducing a neutral centre has never been found. If it had, the difficulties of perpetual motion seekers would have ended, and this problem would have become an established and operating fact. It would only require an introductory impulse of a few pounds, on such a device, to cause it to run for centuries.

We seem to be approaching a theory as to the construction of ether. Hertz has produced vibrations, vibrating more than one hundred million times per second. He made use of the principle of resonance. You all understand how, by a succession of well-timed small impulses, a large vibration may be set up.

One of the most arduous problems is that of energies acting at distances. Are they real? Of all those that appear incontrollable, one only remains, gravitation. Will it escape us also?

An infinitely subtle substance, out of which all other substances are constituted, in varying forms, passes back again into simplicity. The same principle underlies the harmonies of music and the motion of heavenly bodies.

For it is well known that bodies act upon one another by the attraction of gravity, magnetism, and electricity; and these instances show the tenour and course of Nature and make it not improbable that there may be more attractive powers than these. For Nature is very consonant and comfortable to herself.

After having witnessed, on several occasions and under favourable circumstances, Mr. Keely's experiments in what he terms sympathetic vibration, I am satisfied that he has made new and important demonstrations in physical science. He has made manifest the existence of natural forces that cannot be explained by any known physical laws, and has shown that he possesses over them a very considerable control.

Is not ether infinitely more rare and more subtle than air, and exceedingly more elastic and more active? Does it not easily penetrate all bodies? And is it not by its elastic force diffused through the universe?

It may be said that if all things come from only one cause or internal source, acting within itself, then motion and matter must be fundamentally and essentially one and the same, and we may look upon matter as being latent force and upon force as being free matter.

Electricity is in principle as material as water; so it appears, and Mr. Carl Hering has expressed the fact with much of clearness and force. He says, It is a well-known fact that the quantity of electricity measured in coulombs never is generated, never is consumed, and never does grow less, excepting leakage. The current flowing out of a lamp is exactly the same in quantity as that going into it; the same is true of motors and of generators, showing that electricity of itself is neither consumed while doing work nor is it generated.

Those who occupy themselves with the mysteries of molecular vibration bear the victorious wreaths of successful discovery, and show that every atom teems with wonders not less incomprehensible than those of the vast and bright far-off suns.

The famous Keely motor, which has been hovering on the horizon of success for a decade, is but an attempt to repeat in an engine of metal the play of forces which goes on at the inmost focus of life, the human will, or in the cosmic spaces occupied only by the ultimate atoms.

When the truth is made known, it will unwarp the complications of man's manufacture; and show everything in nature to be very simple.
