Abstract

2961. Rose, A. C., and Perry, W. M. Feb. 14. Teaching geography, geometry, and astronomy. -A device for teaching the meaning of latitude and longitude, applicable also to other analogous purposes involving the location of a point on a sphere, comprises two fixed rings a, b at rightangles to one another, and a rotatable ring or half-ring c provided with a pointer e. The ring c is pivoted in the ring a with its axis c<1> perpendicular to the plane of the ring b, and is provided with a pointer d moving over graduations on the ring b. The latitude and longitude of any point to which the pointer e is directed are given respectively by the reading of the pointer e on the ring c and the reading of the pointer d on the ring b. A pointer f, when set in line with the pointer e, indicates the nadir of the point under consideration. The ring a is provided with three pegs g by means of which it can be positioned with the axis c<1> vertical or inclined, for example to correspond with the earth's axis. When the axis is so inclined, the direction of the pole star may be indicated, and the relation between the altitude of the pole star at any point and the latitude of the point may be demonstrated, by a device consisting of two bars pivoted together, one of which is adapted to be secured tangentially to the ring c, and the other to be set parallel to the axis c'.
