The present example, like the late Bill, was an undergrown creature, and had the same curiously-twisted nose, the same asymmetrical face and similar ears large, flat ears that stood out from his head like the handles of an amphora, that had strongly marked Darwinian tubercles, unformed helices and undeveloped lobules. Lombroso would have loved him.
In this way twelve helices were "superposed, each containing an average length of wire of twenty-seven feet, and all in the same direction.
For purposes of warfare, then, it may be dismissed as totally useless. "In this machine, as you see, I have combined the two principles. These helices on the masts will lift the dead weight of the ship perpendicularly without the slightest help from the side-planes, which are used to regulate the vessel's flight when afloat.
A more symmetrical disposition of them could, however, be adopted by placing them zigzag, or in such a way as to form two helices, one of which would move in a particular direction, and the other in a different way.
Their levitator helices moaned dismally, and as their long, slanting shadows slid over the assembled thousands, it seemed that they cast a prophetic pall; that there was a hush of foreboding. But the psychological expert high in a nearby tower immediately noted the slump in the psycho-radiation meter whose trumpet-shaped antenna pointed downward.
"Repetition of the experiments with a battery of one hundred and twenty pairs of plates produced no other effects; but it was ascertained, both at this and at the former time, that the slight deflection of the needle occurring at the moment of completing the connection was always in one direction, and that the equally slight deflection produced when the contact was broken was in the other direction; and, also, that these effects occurred when the first helices were used.
One of these helices was connected with a galvanometer, the other with a voltaic battery of ten pairs of plates four inches square, with double coppers and well charged; yet not the slightest sensible deflection of the galvanometer needle could be observed. "A similar compound helix, consisting of six lengths of copper and six of soft iron wire, was constructed.
Herein the aeroplane has the advantage over the aerostat even when the aerostat is furnished with the means of locomotion. Nevertheless Robur had thought that the simpler his contrivance the better. And the screws the Saint Helices that had been thrown in his teeth at the Weldon Institute had sufficed for all the needs of his flying machine.
"Well," he explained as he turned over the notes and sketches, "the primary principle involved in the construction of such a gun consists in impelling the projectile by the magnetic action of a solenoid, the sectional coils or helices of which are supplied with current through devices actuated by the projectile itself.
My first instrument was made up of an old picture or canvas frame fastened to a table; the wheels of an old wooden clock moved by a weight to carry the paper forward; three wooden drums, upon one of which the paper was wound and passed over the other two; a wooden pendulum, suspended to the top piece of the picture or stretching-frame, and vibrating across the paper as it passes over the centre wooden drum; a pencil at the lower end of the pendulum in contact with the paper; an electro-magnet fastened to a shelf across the picture or stretching frame, opposite to an armature made fast to the pendulum; a type rule and type, for breaking the circuit, resting on an endless band composed of carpet-binding; which passed over two wooden rollers, moved by a wooden crank, and carried forward by points projecting from the bottom of the rule downward into the carpet-binding; a lever, with a small weight on the upper side, and a tooth projecting downward at one end, operated on by the type, and a metallic fork, also projecting downward, over two mercury cups; and a short circuit of wire embracing the helices of the electro-magnet connected with the positive and negative poles of the battery and terminating in the mercury cups."
