DEFINITIONS.

1. THE Terrestrial Globe is an artificial representation of the earth; having the four quarters of the world, the different empires, kingdoms, countries and states; the several oceans, seas and principal rivers; the chief cities, towns, &c. truly de'ineated on its surface, according to their relative situation on the earth.

2. The Celestial Globe is an artificial representation of the heavens; having the fixed stars laid down on its surface, according to their natural order in the heavens. The student must suppose himself placed in the centre of this globe, and viewing the stars in the concave surface.

3. The Axis of the Earth is an imaginary line passing through its centre, on which it revolves; and is represented by the wire that passes through the centre of the artificial globe from north to south.

4. The Poles of the Earth are those two points, where the axis is supposed to cut its surface; the one
