There are properties or modes of vibration which can direct the component molecular vibrations of a mass to the neutral center of that mass. These modes of vibration are called "neutral attraction", "neutral affinity", "negative attraction" or "polar negative attraction."
He [Keely] says "After vain attempts to come more closely to what I term a 'radiophonic vibratory position with microscopic adjustments' I have only been able to reach a few true and standard positions which I can satisfactorily analyze. There is one principle underlying all and this principle is the key."
He [Keely] announced in 1888 that he had discovered this "sympathetic vibration" to be associated both positively and negatively with the polar stream.
The inaudible vibrations of matter and its higher states, affect the magnetic needle. In Keely's researching instruments, he caused these inaudible vibrations to alter the vibration of light in such a manner as to produce sound colors.
