Thus amid all the modifications of that which is the real physical basis of all matter, we find indissolubly associated with each and all of the varied forms and modifications certain motions which are analogous to each other. In the aetherial atom itself, so infinitesimal in its proportions that even our imagination is almost strained in our attempt to conceive it, yet even here we have rotation and translation in an orbit, such rotation and translation being due to the motions of the electro-magnetic Aether. Then in the gaseous forms of matter into which these atoms may be condensed, we find the same two essentials, of matter and motion, of rotation and translation in an orbit, always working harmoniously together, through the motions of the selfsame Aether, which gives rise to the attraction and repulsions of the atoms. Then following the principle into the planetary world, and taking the planet Saturn with its ring of satellites as an example, we find again the same two factors ever working in unison and in harmony, with their incessant rotation and translation in an orbit, forming a complete and perfect unity in themselves, such unity being due to the pressures and tensions of the Aether combined with its rotatory character. Then going a step further, we find a number of planets, with or without satellites, all rotating around one central body, that rotation and translation again being due to the motions of the rotating electro-magnetic Aether, combined with its pressures and tensions. For millions of years, so far as we can tell, this solar system of ours has been moving through space as one complete unit. Then out in stellar space there are millions of such systems, each distinct and perfect in themselves, each of which is made up of exactly similar parts to our solar system, these innumerable systems being doubtless joined together by the same electro-magnetic Aether, forming one larger and grander unity, known as a constellation. Then these constellations, increasing in their number, are again joined together, and form a still larger unity called a Galaxy; and galaxy being joined to galaxy, constellations to constellations, we get such an ocean of suns and stars like that known as the Milky Way, the ultimate whole revealing in all its beauty and harmony the unison of the two essentials of matter and motion. It may even be that all the oceans of suns and stars, that exist in far-off space, are joined together by one common bond, the universal electro-magnetic Aether by its two complementary motions, the centripetal and the centrifugal, the whole forming one ultimate unity which we call the Universe, having for its centre one common point or central orb, which indeed forms the centre of gravity of the entire Universe.
