- Polarized Ringer
If an electromagnet, a permanent magnet, and a pivoted armature be related to a pair of gongs as shown , a polarized ringer results. It should be noted that a permanent magnet has both its poles presented (though one of the poles is not actually attached) to two parts of the iron of the electro-magnet. The result is that the ends of the armature are of south polarity and those of the core are of north polarity. All the markings relate to the polarity produced by the permanent magnet. If, now, a current flow in the ringer winding from plus to minus, obviously the right-hand pole will be additively magnetized, the current tending to produce north magnetism there; also the left-hand pole will be subtractively magnetized, the current tending to produce south magnetism there. If the current be of a certain strength, relative to the certain ringer under study, magnetism in the left pole will be neutralized and that in the right pole doubled. Hence the armature will be attracted more by the right pole than by the left and will strike the right-hand gong. A reversal of current produces an opposite action, the left-hand gong being struck. The current ceasing, the armature remains where last thrown. - Adaption of Horned Poppy for needlework

- The Solar System, or the orbits of the planets
The Sun is placed in the midst of an immense space, wherein six opaque spherical bodies revolve about him as their center. These wandering globes are called the Planets, who, at different distances, and in different periods, perform their revolutions from West to East, in the following order: 1. ☿ Mercury is nearest to the Sun of all the planets, and performs its course in about three months. 2. ♀ Venus in about seven months and a half. 3. ♁ The Earth in a year. 4. ♂ Mars in about two years. 5. ♃ Jupiter in twelve. And lastly, ♄ Saturn, whose Orbit includes all the rest, spends almost 30 years in one revolution round the Sun. The distances of the Planets from the Sun are nearly in the same proportion as they are represented in figure. Supposing the distance of the Earth from the Sun to be divided into 10 equal parts; that of Mercury will be about 4 of these parts; of Venus 7; of Mars 15; of Jupiter 52; and that of Saturn 95. - Dancer 3
