Now when the condenser is fully charged it discharges through the spark gap and then the electric oscillations set up surge to and fro through the closed circuit.
This observation is connected with opinions which geologists have long formed respecting the position of the high chains of mountains, and the direction of their steepest declivities; but the existence of the Cordillera of Caracas, and the frequency of the oscillations on the eastern and northern coast of Terra Firma, in the gulf of Paria, at Carupano, at Cariaco, and at Cumana, render the accuracy of that opinion doubtful.
The forest of the dirt-bed, as before hinted, was not everywhere the first vegetation which grew in this region. Besides the lower bed containing upright Cycadeae, before mentioned, another has sometimes been found above it, which implies oscillations in the level of the same ground, and its alternate occupation by land and water more than once.
The latter is then made to flow through a vacuum tube oscillator when it is converted into high frequency oscillations and these are varied, or modulated, as it is called, by a microphone transmitter such as is used for ordinary wire telephony. The energy of these sustained modulated oscillations is then radiated into space from the aerial in the form of electric waves.
In an instant the aeronaut is launched into space with a rapidity in comparison with which the wild flights of the balloon are but gentle oscillations.
The monotonous rocking of the boat and the ripple of the water had, in some sort, quieted the unhappy Claude. When the boatman had taken his departure, he remained standing stupidly on the strand, staring straight before him and perceiving objects only through magnifying oscillations which rendered everything a sort of phantasmagoria to him.
In the bitterness of something like despair she thought herself a deluded and culpable enthusiast, worthy of ridicule, of contempt, of condemnation. There were no longer any oscillations of her mind toward the old belief; the foundations of sand had been swept away, and there was no space to make a reconstruction.
The Mormon incidentally and accidentally adopted polygamy. The Quakers have for the best part looked with disfavor on passionate love. In the worship of Deity they separate women from men. But all oscillations are equalized by swingings to the other side. The Quakers have often discarded a distinctive marriage-ceremony, thus slanting toward natural selection.
All geological facts tell us plainly that each area has undergone numerous slow oscillations of level, and apparently these oscillations have affected wide spaces.
That the oscillations of the pendulum are caused by the earth, is proved by similar evidence. Those oscillations take place between equidistant points on the two sides of a line, which, being perpendicular to the earth, varies with every variation in the earth’s position, either in space or relatively to the object.
