Fire, air, earth, and water are bodies and therefore solids, and solids are contained in planes, and plane rectilinear figures are made up of triangles. These we may fairly assume to be the original elements of fire and the other bodies; what principles are prior to these God only knows, and he of men whom God loves.
For the Rectilinear type of harmonograph wooden rods 5/8 to 3/4 inch in diameter will be found very suitable. They cost about 2d. each. Be careful to select straight specimens. The upper pendulum of the Miniature Twin Elliptic type should be of stouter stuff, say a broomstick; that of the Goold apparatus stouter still.
It had the appearance of brilliant rays. The light was most dense close to the border of the moon, and became gradually and uniformly more attenuate as its distance therefrom increased, assuming the form of diverging rays in a rectilinear line, which at the extremity were more divided, and of an unequal length; so that in no part of the corona could I discover the regular and well-defined shape of a ring at its outer margin.
Peter Cooper's particular device was a plan to do away with the crank, and transform the rectilinear motion of the piston into rotary motion. He figured it out that this would save two-fifths of the steam, and so stated in his application for a patent, a copy of which is before the writer. The Patent Office then was looked after by the President in person.
Place a rectilinear piece of this conductor in a horizontal position over an ordinary magnetic needle so that it is parallel to it. The magnetic needle will be set in motion and will deviate towards the west under that part of the conductor which comes from the negative pole of the galvanic battery.
The striae which are made, and the deep grooves which are scooped out by this action, are rectilinear and parallel to an extent never seen in those produced on loose stones or rocks, where shingle is hurried along by a torrent, or by the waves on a sea-beach.
The movements are rectilinear, but two rectilinear vibrations of equal amplitude acting at right angles to each other generate a circle if they alternate precisely, an ellipse if the alternations are less regular or the amplitudes unequal. A cyclic vibration may also be obtained from a pendulum free to swing in a rotary path.
On page 182, it is stated, that Newton's proving, that, if a body revolved in an elliptical orbit with the sun as a focus, the force of gravitation toward the sun would always be in the inverse ratio of the square of its distance, "was equivalent to proving, that, if a body in space, free to move, received a single impulse, and at the same moment was attracted to a fixed centre by a force which diminished as the square of the distance at which it operated increased, such a body, thus deflected from its rectilinear path, would describe an ellipse," etc.
Parliament was the field, Government the office. How many conversations had passed between him and Diana on that patriotic dream! She had often filled his drooping sails; he owned it proudly: and while the world, both the hoofed and the rectilinear portions, were biting at her character! Had he fretted her self-respect? He blamed himself, but a devoted service must have its term. The paper of Mr.
The king had seen all kind of gnomes, goblins, and kobolds at his coronation; but they were quite rectilinear figures compared with the insane lawlessness of form in which the Shadows rejoiced; and the wildest gambols of the former were orderly dances of ceremony beside the apparently aimless and wilful contortions of figure, and metamorphoses of shape, in which the latter indulged.
