"The coil is of flat, rectangular shape, with a narrow central opening just large enough to allow one of the magnets of the astatic system to swing freely. The other magnet swings over a graduated circle placed on the top of the coil, and serves also as an index. Sometimes a mirror and scale are substituted for the index and graduated circle. The sole on which the coil stands is movable on a fixed piece which can be levelled by means of three screws." &mdash Encyclopedia Britannica, 1893

"In the year 1589 the stocking-frame, the machine which mechanically produces the looped stitch in hosiery, was invented by the Rev. William Lee, a graduate of Cambridge, and native of Woodborough, near Nottingham. The fundamental principle of the apparatus consists in the substitution of a seperate hooked or barbed needle for the support and working of each loop, in place of the system whereby an indefinate number of loops are skewered on one or more wires or needles. At R is seen a thread of yarn passed over the needle stalks and within the terminal hooks. The yarn, it will be observed, is waved or depressed between each pair of needles, whereby sufficient yarn is secured to form the seperate loops of uniform size, and thus produce a regular equal fabric." — Encyclopedia Britannica, 1893

"A class of radiate animals, the highest in organisation of the great division of the animal kingdom. They have a digestive and a vascular system; for the former, however, there is in many of them only a single orifice; a circular and radiating nervous system has been observed in manyl they are especially characterised by their well-organised skin which in many is strengthened by calcareous plates, and in some also has the additional protection of numerous long spines. a, Asterias Tesselllata (Asteriadae); b, Spatangus (Echinidae) or sea-egg." — Chambers' Encyclopedia, 1875

"System of Wheels.—As the wheel and axle is only a modification of the simple lever, so a system of wheels acting on each other, and transmitting the power to the resistance, is only another form of the compound lever. The first wheel a, by means of the teeth, or cogs, around its axle, moved the second wheel, b, with a force equal to that of a lever, the long arm of which extends from the center to the circumference of the wheel, where the power p is suspended, and the short arm from the same center to the ends of the cogs. The dotted line c, passing through the center of the wheel a, shows the position of the lever, as the wheel now stands." —Comstock, 1850

Having now given a short account of each planet composing the solar system, the relative situation of their several orbits, with the exception of those of the Asteroids, are shown in this figure. The orbits are marked by the signs of each planet, of which the first, or that nearest the Sun, is Mercury, the next Venus, the third the Earth, the fourth Mars then come those of the Asteroids, then Jupiter, then Saturn and lastly Herschel." —Comstock, 1850

"The elliptical circle being supposed to be the Earth's orbit, with the Sun, S, in one of the foci. Now the spaces, 1, 2, 3, etc., though of different shapes, are of the same dimensions, or contain the same quantity of surface. The Earth, we have already seen, in its journey round the Sun, describes an ellipse, and moves more rapidly in one part of its orbit than in another. But whatever may be its actual velocity, its comparative motion is through equal areas in equal times. Thus its center passes from E to C, and from C to A, in the same period of time, and so of all the other divisions marked in the figure." —Comstock, 1850
