And, moreover, he shows that the water oscillates according to the two principal dimensions of the lake; thus, giving rise to longitudinal Seiches and transverse Seiches. They occur in series of tautochronous oscillations of decreasing amplitude; the first wave produced by the action of a given cause having a maximum amplitude. Causes.
Among sonorous bodies which move in the same way, only very much faster, we may mention tuning forks." Tyndall says again: "When a common pendulum oscillates, it tends to form a condensation in front and a rarefaction behind.
The German army moves in one piece, in one absolute unity; the Crown Prince of Saxony is on the height of Mairy, whence he surveys the whole action; the command oscillates in the French army; at the beginning of the battle, at a quarter to six, MacMahon is wounded by the bursting of a shell; at seven o'clock Ducrot replaces him; at ten o'clock Wimpfen replaces Ducrot.
There is no need, as happens amongst the migrants, for the period of organic change to conform rigidly to the growth of any particular condition in the environment, and hence for a time the bird oscillates between two modes of behaviour between that one organised by frequent repetition and that one determined by the functioning of this new disposition.
Sound travels in air at about 1130 feet per second, and if the vibrating body, giving out the sound, oscillates sixteen times in one second, it follows that, spreading over this 1130 feet, there will be sixteen waves, giving a length of about 70 feet to each wave.
The amount of superior families oscillates rather than changes; that is, it fluctuates within fixed limits; and, for all inferior families, being composed either of shopkeepers or of menial servants, they are determined by the number, or, which, on a large average, is the same, by the pecuniary power, of their employers.
"Heaven will reward her for the interest she takes in the heathen world." "Truly, if she hath not now, she will have there a monument of gold," Mr. Hadger piously pursues, adding a sigh. "There! there! my neuralgy; it's all down my left side. I'm not long for this world, you see!" Mrs. Swiggs breaks out suddenly, then twitches her head and oscillates her chin.
Beyond the peninsula the horizon was bounded by Cape Macanao, the black rocks of which rise amid the waters like an immense bastion. The farm of the Cocollar, situated at the foot of the Turimiquiri, is in latitude 19 degrees 9 minutes 32 seconds. I found the dip of the needle 42.1 degrees. The needle oscillates 229 times in ten minutes.
"There is no such thing," says Cicero, "as Roman historical composition"; and, so far as we can judge, this is no more than the simple truth. The man of research turns away from writing history, the writer of history turns away from research; historical literature oscillates between the schoolbook and the romance.
This process over, if he still feels pain in the lower extremities, his foot is buckled upon an iron sole which oscillates in any direction according to its method of connection with the power, from side to side, so as to twist the leg about forty-five degrees each way, up and down, to imitate the trotting of the foot, or with a motion which combines several.
