 ... the zenith point by four times that quantity, i. e. by 52@ 41' 20'', a space which corresponds to the path which she will describe during the entire journey of the projectile. But, inasmuch as it is equally necessary to take into account the deviation which the rotary motion of the earth will impart to the shot, and as the shot cannot reach the moon until after a deviation equal to 16 radii of the earth, which, calculated upon the moon's orbit, are equal to about eleven degrees, it becomes necessary to add these eleven ...

... arrangement, although in its details it more or less resembles the analogous machines of Schoenherr, Crompton, and Hartmann. The lifting of the shuttles is effected by two sectors, a1, a2, arranged on the two sides of the loom, and the rotary motion of which acts upon the box, c, by means of the lever, b, the box being caused to descend again by the spring, d. Parallel with the breast beam there is mounted an axle, e, and upon one of the extremities of this is fixed the sector, a1, while the other extremity carries two ...

... absolute hardness which has been attributed to material atoms from the time of Lucretius downward may be dispensed with. Somewhat in the same way that a loosely suspended chain becomes rigid with rapid rotation, the hardness and elasticity of the vortex-atom are explained as due to the swift rotary motion of a soft and yielding fluid. So that the vortex-atom is really indivisible, not by reason of its hardness or solidity, but by reason of the indestructibleness of ...

... no attempt whatever will be made to give a technical explanation of the mechanism of the winding motion. It may be said that it was a special application of the Sun and Planet motion originally utilised by Watt in his Steam Engine, for obtaining a rotary motion of his fly-wheel. ...

... breadth. Possibly the river has merely worn an arm in its side, leaving an extensive bulge standing out in the river, and connected with the mainland by an isthmus. The river striking in this arm, and not having sufficient scope to rebound toward the other bank, is thrown into a rotary motion, forming almost a whirlpool. The action of this motion upon the banks soon reduces the connecting neck, which separates and blocks the waters, until, at last, no longer able to cope with the great weight resting against it, it gives way, and the ...

... AND TIDES.—Many attempts have been made to harness the waves and the tide and some of them have been successful. This effort has been directed to the work of converting the oscillations of the waves into a rotary motion, and also to take advantage of the to-and-fro movement of the tidal flow. There is a great field in this ...

... head, Dr. Lawson, have much advanced this branch of science. The interesting question, Does our climate change? seems to be answered thus far in the negative, by registers kept in Massachusetts and New York. There are two rival theories of storms. That of Redfield, of a rotary motion of a wide column of air, combined with a progressive motion in a curved line. Espy builds on the law of physics, examines the action of an upmoving column of air, shows the causes of its motion and the results, ...

... flat on one side, with the ends and the other side rounding. One end of the stick is grasped in one hand with the convex edge forward and the flat side up and thrown upward. After going some distance and ascending slowly to a great height in the air with a quick rotary motion, it suddenly returns in an elliptical orbit to a spot near the starting point. If thrown down on the ground the boomerang rebounds in a straight line, pursuing a ricochet motion until the object is struck ...

... steam over the ordinary coach roads. He filled a quarto drawing-book with different plans for these, and covered the idea in one of his patent specifications. Boulton suggested in 1781 that the idea of rotary motion should be developed, which Watt had from the first regarded as of prime importance. It was for this he had invented his original wheel engine, and in his first patent of 1769 he describes one method of ...

... power is obtained by terrific speed of the moving parts, as though a steam engine, to avoid great pressure in its cylinders, had a long stroke and ran at great piston speed, which, however, is no disadvantage to the rotary motion of the electric motor, there being no reciprocating cranks, etc., that must be started and stopped at each revolution. "To obviate the necessity of gearing to reduce the number of revolutions to those possible for a large screw, this member is made very small, and allowed to revolve ...

... tornadoes are of frequent occurrence, and the damage is often fearful, whole towns being completely swept away. In the East Indies, and on the coast of India, these storms are known as Cyclones, because of their rotary motion—the Greek word Ruklos, from which "Cyclone" is derived, meaning "a whirl". A cyclone frequently extends across a great belt, and is from fifty to five hundred miles in width. It may last for hours, and if it occurs on the ocean it destroys most of ...

... are provided with an improved form of governor operating on the same principle, but embodying several important features. First, the spindle sleeve is integral with the governor yoke, and the whole rotates about a vertical stationary spindle, so that two motions are encountered—a rotary motion and an up and down motion, according to the position taken by the governor. This spiral motion almost entirely eliminates the effect of friction of rest, and thereby enhances the sensitiveness of the governor. Second, the governor weights move outward on a parallel motion opposed ...

... and the ballast should be so adjusted that there is nearly equilibrium before leaving, else the rapidity of ascent is too great, and has to be checked by parting with gas. It is almost impossible to liberate the balloon in such a way as to avoid giving it a rotary motion about a vertical axis, which continues during the whole time it is in the air. This rotation makes it difficult for those in the car to discover in what direction they are moving; and it is only by looking down along ...

... bank of what was the stream at its average stage, long poles had been used, and one of these long and supple poles was now partly submerged. The swift current bent it in the middle until it would spring out of the water and drop back higher up. It was thus kept in a rotary motion, making the sound which he had mistaken for the paddling of a canoeman. With this discovery departed all thought of human help from ...

... in this insistent repetition of the same figure in the left hand, and a very clear note of Chopin's genius is seen when he changes this bass figure from E major to E-flat major. This change, although apparently not significant on paper, has the keyboard peculiarity of giving the left hand a rotary motion in the opposite direction from that necessitated in the E major, and in three measures of it the player unwinds himself, as it were, and is ready to begin again with the original figure. Still another pleasing ...

The presence of ice in the vicinity of that extreme northern point was feared by no one concerned in the expedition, for it was believed that the rotary motion of the earth would have a tendency to drive it away from the pole ...

... makes little or no difference whether the water moves sidelong on the spade or the latter progresses through the liquid; the ore will range itself accurately all the same. Consequently, if a circular tank be used, and if the water be set in rotary motion, the ore on a sheet of glass, held steady, will arrange itself in the same way. If the ore be fed in small streams of water down the inclined surfaces of sloping glass, or other smooth shelves set ...
