His relatively low speed was not his fault, because he went through all the motions of frenzied flight. His legs twinkled as he ran. But his feet slid backward. He moved with a sort of dignified celerity, running fast enough for ten times the speed, upon a surface which had a frictional coefficient far below that of the smoothest possible ice.
The frictional tone is chiefly due to that general attitude of blame which I have already condemned as being absurd and unjustifiable. As, by constant watchful discipline, we gradually lose this silly attitude of blame, so the tone will of itself gradually change.
We came past the window whose contents I was presently to know by heart, a very ordinary chemist's window except that there was a frictional electrical machine, an air pump and two or three tripods and retorts replacing the customary blue, yellow, and red bottles above.
Her white fire is the frictional fire of the last strange, intense watery matter, as this matter fights its way out of combination and out of combustion with the sun-stuff. To the pure polarity of the moon fly the essential waters of our universe. Which essential waters, at the moon's clue, are only an intense invisible energy, a polarity of the moon.
He made also a similar device, more closely resembling the modern Leyden jar, from a thermometer tube partly filled with water and a wire tipped with a ball of lead. With these devices he found that he could retain the charge of electricity for several hours, and could produce the usual electrical manifestations, even to igniting spirits, quite as well as with the frictional machine.
There were many other researches made by Faraday, such as his experiments on disruptive electric discharges, his investigations on the electric eel, his many researches on the phenomena both of frictional electricity and of the voltaic pile, his investigations on the contact and chemical theories of the voltaic pile, and those on chemical decomposition by frictional electricity; these are but some of the mere important of them.
The long wished for full explanation of the relations between frictional electricity, voltaism, magnetism, heat, and light, seems likely soon to be obtained; and, consequently, also the exact physical relations of the vital or formative force of animals and plants.
It is not a phenomenon of mechanical impact or frictional resistance, since neither are possible in the ether. Molecular cohesion exists between very wide ranges. When strong, so if one part of a body is moved the whole is moved in the same way, without breaking continuity or the relative positions of the molecules, we call the body a solid.
If the rock in the fair-way is got ready before my return, blast it at once, without waiting for me. You will find one of Siebe and Gorman's voltaic batteries in my lodging, also a frictional electrical machine, which you can use if you prefer it. In the store there is a large supply of tin-cases for gunpowder and compressed gun-cotton charges.
M is a Siemens electric motor running at 650 revolutions per minute; E is a combination of box gearing, frictional clutch, and chain pinion, and from this pinion a steel chain passes around the chain-wheel, H, which is free to revolve upon the axle, and carries within it the differential pinion, gearing with the bevel-wheel, B², keyed upon the sleeve of the loose tram-wheel, T², and with the bevel-wheel, B¹, keyed upon the axle, to which the other tram-wheel, T¹, is attached.
