... retreat; but I was confoundedly mistaken; for at the very moment I thought myself victorious, the enemy attacked my rear, and having got a reasonably good mouthful out of it, was fully prepared to take another before I was rescued. Egad, I thought for a time the beast had devoured my entire centre of gravity, and that I should never go on a steady perpendicular again." "Upon my word," said Sir Jonah Barrington, to whom Curran related this story, "the mastiff may have left you your centre, but he could not have left much gravity ...

... conclusion that there was no connection of the force with attractive or repulsive influences.' With the most refined ingenuity he shows that, under certain circumstances, the magne-crystallic force can cause the centre of gravity of a highly magnetic body to retreat from the poles, and the centre of gravity of a highly diamagnetic body to approach them. His experiments root his mind more and more firmly in the conclusion that 'neither attraction nor repulsion causes the set, ...

... as a building is, and yet for a time keep upright by dead habit. But a new perception, a sudden emotional shock, or an occasion which lays bare the organic alteration, will make the whole fabric fall together; and then the centre of gravity sinks into an attitude more stable, for the new ideas that reach the centre in the rearrangement seem now to be locked there, and the new structure ...

... the charge, is responsible for its driving force. In the days of real intellectual leadership the mastery of ideas prevailed and Public Opinion was considered as the triumph of an idea. But in our days of so called democratic equality the centre of gravity of this power has shifted from the leader to the multitude. De Tocqueville in his book "Democracy in America" [1] has a remarkable page, illustrating this point. "The nearer the people," he writes, "are drawn to a common level of an equal and similar ...

All our experience shows that the ice was more developed on some meridians than others; probably nowhere in the whole world did it lie so thick as along the American continents; and everywhere it must have been greater over ...

... cuffing each other on the wing in a kind of playful skirmish; and when they move from one place to another, frequently turn on their backs with a loud croak, and seem to be falling on the ground. When this odd gesture betides them, they are scratching themselves with one foot, and thus lose the centre of gravity. Rooks sometimes dive and tumble in a frolicsome manner; crows and daws swagger in their walk; woodpeckers fly with an undulating motion, opening and closing their wings at every stroke, and so are always rising and falling in curves. All of ...

Bathsheba felt the unpleasant symptoms after two or ...

... tombs, the subject is occasionally indicated by only two or three rapid strokes of the reed (fig. 178). Elsewhere, the outline is fully made out, and the figures only await the arrival of the sculptor. Some designers took pains to determine the position of the shoulders, and the centre of gravity of the bodies, by vertical and horizontal lines, upon which, by means of a dot, they noted the height of the knee, the hips, and other parts (fig. 179). Others again, more self-reliant, attacked their subject at once, and drew in the figures ...

... says, "an elephant descending a bank of too acute an angle to admit of his walking down it direct, (which, were he to attempt, his huge tody, soon disarranging the centre of gravity, would certainly topple over,) proceeds thus. His first manoeuvre is to kneel down close to the edge of the declivity, placing his chest to the ground: one fore-leg is then cautiously passed a short way down the slope; and if there is no natural protection ...

... which appears to me truly significant. After the repeal of the Stamp Act, "the colonies fell," says this assembly, "into their ancient state of unsuspecting confidence in the mother country." This unsuspecting confidence is the true centre of gravity amongst mankind, about which all the parts are at rest.

She maintained the equilibrium; for, renowned as she had been all her life at producing havoc among plates, and cups, and bowls, she was never known to be thrown off her own centre of gravity. Another hearty shake of the hand followed, and the major quitted the table. As was usual on all great and joyous occasions in the family, when the emotions reached the kitchen, that evening was remarkable for a "smash," in which ...

... Provincial Parliaments followed the Parliament of Paris. After this the King had no alternative but to try the experiment of calling the States-General. They met on May 4, 1789, and instantly an administrative system, which no longer rested upon a social centre of gravity, crumbled, carrying the judiciary with it. At first the three estates sat separately. If this usage had continued, the Clergy and the Nobles combined would have annulled every measure voted by the Commons. For six weeks the Commons waited. Then on June 10, the Abbe Sieyes said, "Let us cut the cable. ...

... water-plane has to be set higher than that of a land aeroplane, so that it may not come into contact with the waves. This tends to tip the craft forwards, and thus make the nose of the float dig in the water. To overcome this the float is set well forward of the centre of gravity, and though this counteracts the thrust when the craft "taxies" along the waves, it endangers its fore-and-aft ...

... quick-firing guns; it must certainly take the strain of recoil off the centre of the axle, which recoil we found cracked our axles as we used them (once in my own guns) so badly that the whole thing had to be shifted and replaced. Another advantage it has is to lower the whole gun and mounting, and the centre of gravity of the weight of it and carriage, and therefore the gun is much harder to upset on rocky ground or going up steep precipices, as we had to do in Natal. This detail of wheels and axle is, I think, the most important one almost in a field carriage. The axle I mention ...

... that 'he prophesies of times that are far off'? Yes! and No! Yes! it is true, and it is the great glory of Christianity that it shifts the centre of gravity, so to speak, from this poor, transient, contemptible present, and sets it away out yonder in an august and infinite future. It brings to us not only knowledge of the future, but certitude, and takes the conception of another life out of the region of perhapses, possibilities, ...

... doctrine of Aristippus, the Cyrenaic, the errant disciple of Socrates. He made pleasure the end of life, and taught that it might be sought without a greater regard to customary morality than was made prudent by the penalties to be feared as a consequence of its violation. Where the centre of gravity of the system of the Cyrenaics falls is evident from their holding that "corporeal pleasures are superior to mental ones," and that "a friend is desirable for the use which we can make of him."
