    ive know that the repuliions and attractions, cab¬ led magnetic, are effeded. Confequently, in this cafe, we know that the two didant bodies, do not attract each other by any immaterial fphcres, but by a medium of par¬ ticles of matter, in an atmofpheric date ; therefore, we are under no necedity of fuppofing, that any two didant particles at trad:, or repel each other, by immaterial powers ,* but, reafoning from ana¬ logy, avoiding the multiplication of caufes to produce effeds, we mud, and can rationally, only conclude, that every appearance of attradion, or of repulfion, taking place between didant bodies, < % i is effeded by a dmilar intermedium of material particleSy in the date of an invifible atmofphere around one or both of the bodies, which, though didant, produce effeds upon each other.
