Altho’ the number of Stars that can be discerned by the naked eye are so few, yet it is probable there are many more which are beyond the reach of our optics, for through telescopes they appear in vast multitudes, every where dispersed throughout the whole Heaven; and the better our glasses are, the more of them we still discover. The ingenious Dr. _Hook_ has observed 78 Stars in the _Pleiades_, of which the naked eye is never able to discern above 7; and in _Orion_, which has but 80 Stars in the _British_ catalogue (and some of them telescopical) there has been numbered 2000 Stars. [Sidenote: An idea of the Universe.] Those who think that all these glorious bodies were created for no other purpose than to give us a little dim light, must entertain a very slender idea of the Divine Wisdom; for we receive more light from the _Moon_ itself, than from all the _Stars_ put together. And since the _Planets_ are subject to the same laws of motion with our _Earth_, and some of them not only equal, but vastly exceed it in magnitude, it is not unreasonable to suppose, that they are all habitable Worlds. And since the _Fixed Stars_ are no ways behind our _Sun_, either in bigness or lustre, is it not probable, that each of them have a system of _Planetary Worlds_ turning round them, as we do round our Sun? And if we ascend as far as the smallest Star we can see, shall we not then discover innumerable more of these glorious bodies, which now are altogether invisible to us? And so _ad infinitum_, thro’ the boundless space of the universe. What a magnificient idea must this raise in us of the _Divine Being_! Who is every where, and at all times present, displaying his Divine Power, Wisdom and Goodness, amongst all his Creatures! [Illustration] _The_ DESCRIPTION _and_ USE _of the_ CELESTIAL _and_ TERRESTRIAL GLOBES. [Sidenote: _Globe_ or _Sphere_.] A _Globe_ or _Sphere_ is a round solid body, having every part of its surface equally distant from a point within it, called its _Center_; and it may be conceived to be formed by the revolution of a semicircle round its diameter. [Sidenote: _Great Circle._] [Sidenote: _Hemispheres._] Any circle passing through the center of the sphere, thereby dividing into two equal parts or segments, is called a _Great Circle_; and the segments of the sphere so divided, are called _Hemispheres_. Every great circle has its Poles and Axis. [Sidenote: _Poles._] The _Poles_ of a great circle are two points on the surface of the sphere, diametrically opposite to one another, and every where equally distant from the said circle. [Sidenote: _Axis._] The _Axis_ of a circle is a right line passing through the center of the sphere, and through the Poles of the said circle, and is therefore perpendicular to the Plane: Therefore [Sidenote: _Secundaries._]
