2j2 OF NATURE. 



attractive force ; and a different quantity of im~ 

 pulfive force is afligncd to each individual globe. 

 Some liars are fixed, and others wandering. 

 Some globes feem to be deftined for attracting, 

 and others for impelling, or being impelled. 

 There are fpheres which have received a com- 

 mon impulfion in the fame direction, and others 

 a particular impulfion. Some ftars are folitary, 

 and* others accompanied with fatellites : Some 

 are luminous, and others opaque mafles. There 

 are planets, the different parts of which fuccef- 

 fively enjoy a borrowed light, and comets, which 

 lofe themfelves in the profundity of fpace, and 

 return, afcer many ages, to receive the influence 

 of folar heat. Some funs appear and difappear, 

 and feem to be alternately kindled and extinguish- 

 ed ; others exhibit themfelves for once, and then 

 vanifh forever. Heaven is a country of great e- 

 vents ; but the human eye is hardly able to per- 

 ceive them. A fun, which perifhes, and deftroys 

 a world, or a fyftem of worlds, has no other 

 effect on our eyes than an ignis fatuus, which 

 gives a tranfitory blaze, and appears no more. 

 Man, limited to the terreftrial atom on which 

 he vegetates, views this atom as a world, and 

 fees worlds onlv as atoms. 



The earth which man inhabits, hardly per- 

 ceptible among the other globes, and totally 

 invifible to the diftant fpheres, is a million of 

 times fmaller than the fun by which it is illumi- 

 nated, and a thoufand times fmaller than fome 

 other planets, which are alio fubjecled to the 



powr'-
