That hope he realised, showing by actual experiment that when his disk rotated currents passed through it, their position and direction being such as must, in accordance with the established laws of electro-magnetic action, produce the observed rotation.
When we got to a place where an examination could be had, it was found that Broady had been so struck by a piece of shell that it went through his overcoat, and then rotated in such a manner as to cut the tails off from his dress coat, so that, after we got to Harrison's Landing the captain went about dressed in that frock coat with the skirts cut off. In other words he was supporting a jacket.
When I released them, it appeared that they had been attracted by Chu Chu's graces, and had offered her overtures of affection, to which she had characteristically rotated with this miserable result. I led her, with some difficulty, warily keeping clear of the riata, to the inclosure, from whose fence I had previously removed several bars.
Let him place an orange in the centre of a round table, and then let him move round the table from a starting-point sideways, ever keeping his face directed towards the orange; and when he has reached his starting-point, he will find that he has rotated once round while he has performed one revolution round the table. In this case the performer represents the moon and the orange the earth.
During this time it must be continuously rotated about its axis, and so held that the edges of the heated zone are sharply defined; i.e., it should not be allowed to move back and forth along its own axis. When so hot that it cannot longer be held in shape, the tube is removed from the flame, and the ends slowly and regularly drawn apart, continuing the rotation of the tube about its axis.
But our science would be different in some respects had we never seen them. We should still have good reason, in Foucault's pendulum experiment, for supposing that the world rotated upon its axis, and that the sun was so far relatively fixed; but we should have no suspicion of the orbital revolution of the world.
The Floriot rolled easily forward, speeded up, and gathered headway. Gabriel suddenly rotated the rising-plane. The great gull soared, careened and took the air with majestic power. The watchers on the mountain-side saw its hooded lights, that glowed upon its compass and barometric-gauge, slowly spiralling upward, ever upward, as Gabriel climbed with his two passengers.
The first change that came under their observation was the rapidity of the sun's appearances and disappearances, forcing them to the conviction that although the comet still rotated on its axis from east to west, yet the period of its rotation had been diminished by about one-half.
It would appear, therefore, that the earth may have been rotating, throughout the whole period which has elapsed from the commencement of the Glacial epoch down to the present time, one, or more, seconds per annum quicker than it rotated during the Miocene epoch.
No one can wonder that the statement was generally received with incredulity, for it was in direct contradiction to the conclusions of other astronomers, who had long believed that Mercury rotated on its axis in a period closely corresponding with that of the earth's rotation that is to say, once every twenty-four hours.
