"The series of experiments, daily for one week, that I am now preparing to give before an expert committee, for the purpose of enabling this committee to make a public announcement of the scientific and commercial value of my system of sympathetic vibratory physics, comprises:
First. - Operation of the polar circuit, drawing power from space, and showing control of various degrees of velocity.
Second. - Sensitization of a polar disk, after having had its complete neutrality to magnetism tested.
Third. - After associating it with the polar test-medium, heavily weighting it to demonstrate its attractive power; the weight remaining suspended to it by this power.(7)
Fourth. - Transmitter connected to the test-medium, while the disk is carrying the weight. Negative vibration transferred; effecting complete dissociation; the disk and weights dropping to the floor.
Fifth. - Rotation of compass needle, on a set of resonators, subservient to any one of the resonators, in defiance of its attraction to the north. Variations given; changing its subservience to different resonators, as the introductory impulse is changed.(8)
Sixth. - Mediums, representing the chords of different masses of metal, made to float in a tall jar of water, with extraordinary changes of position.
Seventh. - Operations of a sensitized globe, by sound.
Eighth. - Operations of the globe under the influence of the improved polar sympathetic transmitter.
Ninth. - Disintegration of water by triple vibration,(9) showing progressive degrees of energy (from molecular to interatomic, etc., etc.) on different rates of transfer." [The Operation of the Vibratory Circuit]
noun: all the chemical processes by which cells produce the energy and substances necessary for life. Food is separated (dissociated) into the parts it is made up of to produce heat and energy, to repair tissues, and to help growth to happen.
noun: the organic processes in a cell or organism that are necessary for life
noun: the marked and rapid transformation of a larva into an adult that occurs in some animals
Metabolism ("change") is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are:
(1) the conversion of the energy in food to energy available to run cellular processes;
(2) the conversion of food to building blocks for proteins, lipids, nucleic acids, and some carbohydrates;
(3) and the elimination of metabolic wastes. [Metabolism]
These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism.
