Some have been observed to arise and vanish in sixteen hours, while some have lasted seventy days : those spots that are formed gradually are gradually dissolved, while those that arise suddenly are suddenly dissolved. The nature and formation of the spots have been the subject of much speculation and conjecture. Some have thought that the sun is an:opaque body, mountainous and uneven, covered all over with a fiery and luminous fluid; that this fluid is subject to edding and flowing, after the manner of our tides, so as sometimes to leave uncovered the tops of rocks or hills, which appear like black spots, and that the nebulosities about them are caused by a kind of froth : others imagined that the fluid whidh sends us so much light and heat, contains a nucleous, or solid globe, wherein are several volcanoes, which, like 2Etna or Vesuvius, from time to time cast up quantities of bituminous matter to the surface of the sun, and form those spots that are seen thereon; and that as this matter is gradually consumed by the luminous fluid, the spots disappear for a time, but are seen to rise again in the same places when those volcanoes cast up new matter : a third opinion is, that the sun consists of a fiery luminous fluid, wherein are immersed several opaque bodies of irregular shapes, and that these bodies, by its motion, are sometimes raised up to the surface of the sun, where they form the appearance of spots, which seem to change their shape according as different sides of them are presented to view : a fourth opinion is, that the sun consists of a fluid in continual agitation; that by the rapid motion of the fluid some parts more gross than the rest are carried up to the surface of the lumirary, like the scum of melted metal rising up to the top in a furnace. But Dr. Wilson's opinion has gained more credit than any of the foregoing ; for he considers the spots to be hollows in the surface of the luminary, and has even observed the spots to be beneath the level of the sun's spherical surface: he considers that the vast body of the sun is made up of two kinds of matter v.ery different in their qualities; that by far the greatest part is solid and dark; and that this dark globe is encompassed with a thin covering of that resplendent substance from which the sun would seem to derive the whole of his vivifying heat'and energy. This supposition will afford a satisfactory solution of the appearance of the spots; because if any part of this resplendent substance slall by any means be displaced, the dark globe must necessarily appear.-The shining substance may be displaced by the action of some elastic vapour, generated within the substance of the dark globe. ::This is the general opinion of the astronomers of the present day. Far the greater number of the celestial bodies preserve the same situation with respect to each other-and these are called fixed stars; arid although these stars are the only marks by which astronomers are enabled to judge of the courses of moveable ones, yet they seem not to be endued with permanency, but to be perishable and destructible by accident, and likewise generable by some natural cause; and astronomers have supposed that every one of the innumerable multitude offixed stars are seans, attended by planets and comets, each of which is an inhabitable world like our own, but of course invisible to us. The strongest argument for this hypothesis is, that they cannot be magnified by telescopes, on account of their extreme distance, Hence, therefore, we must conclude that they shine by their own light, and are as many suns; and those who have formed conjectures concerning their distance, thought that some of them were at least 400,000 times farther from us than we are from the sun ; and, therefore, we may imagine an innumerable number of universes like to that which :we can behold, and extending to infinity. Besides the sun, earth, moon, and fixed stars, there are ten planets-named Mercury, Venus, Mars, Ceres, Palas, Juno, Vesta, Jupiter, Saturn, and Georgium Sidus. These are
