“I have discovered that gravitation is due to the attraction that two bodies in different electrical condition have for each other, and that by changing the condition of one of these bodies so that they are both in the same electrical condition this attraction no longer exists. I have also discovered that the earth is, so to speak, as far as the laws of gravity are concerned, in a state of what we might call for lack of a better name, ‘positive electrical condition,’ and that all objects on the earth, as long as they are not in contact with it, are in what we may call ‘negative electrical condition.’ These remain in this condition so long as they are not in actual electrical contact with the earth and are separated from it by a non-conducting medium such as the atmosphere, glass, hard rubber, etc., and are attracted by it, as is shown by the formulae which I will gladly explain to your gentlemen of science.” And he turned with a bow to Admiral Sir William Brown, who was leaning across the table frowning at him and who with his scrubbing-brush hair, long upper lip, and heavy brows looked more like a Rocky Mountain goat than ever. “I have invented an instrument,” continued Edestone, “which I call a _Deionizer._ With this, so far as regards any phenomena of which we are conscious, I am able to change the electrical condition of an object, provided this object is insulated from electrical contact with the earth. That is, I can change it from the so-called minus condition, which is attracted by the earth, to the plus condition, which being the same condition as the earth, is therefore not attracted by it. The object in that state can be said to have no weight, although frankly for some reason which I have not yet discovered it does not lose its inertia against motion in any direction relative to the earth.” He then took from his pocket the leather case which Underhill readily recognized, and, turning to Lord Rockstone, he said with a slightly quizzical expression: “If your Lordship will be so kind as to stand on a glass plate or block of hard rubber I can with this little instrument which I have in my hand alter your electrical condition from its present minus to that of plus. I can then place you anywhere in this room and keep you there as long as you do not come in contact with any object that, electrically speaking, is in contact with the earth.” This caused Lord Rockstone to give a grim but thoroughly good-natured smile, and Edestone, feeling as if he had somewhat settled scores with the “Hero of the Nile,” continued: “As a less valuable object than one of the most brilliant stars in Great Britain’s crown will answer my purpose just as well, may I ask that one of the servants fetch the glass plate that was brought to the Palace this afternoon with my apparatus.”
