Excerpt from The Cosmosphere: An Instrument Substituting an Orrery, a Planetarium, a Tellurium, a Lunarium, an Armillary Sphere, Celestial and a Terrestrial Globe, for Self-Instruction and for Schools III. A small ball on a wire to represent the sun. Through its centre is laid a transparent or Opaque plane, to show the plane of the orbit or curve in which the earth moves round the sun. In this orbit four small balls, representing the earth, and through their centre other transparent planes, to show the orbit of the moon round the earth, are fixed, and on them are placed smaller balls representing the moon. This part is likewise to be placed, that the ball, called the sun, falls in the centre of the transparent globe, and the wire with the other end in the pole of the ecliptic. This part of the apparatus serves to explain the motions of the earth and moon. IV. A terrestrial globe, of the most improved construe tion, to be placed in the transparent ball, so that the centre of both falls in one point, and the axis of the terres trial globe fits in the poles of the equator of the transparent hemispheres. This axis of the terrestrial globe has a loose prolongation to turn it from the outside of the transparent globe. Round the terrestrial globe lies a ring with proper divisions. It is fixed to another ring, and a semi-ring standing perpendicularly on both, and equally distant from the intersection of both. By a screw-nut and catch on each side of the axis of the terrestrial globe, this is fixed to the undivided ring, to fix this in any required position. Where the semi-ring meets the ring without divisions. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
