They have likewise discovered two lesser stars, or satellites, which revolve around Mars, whereof the innermost is distant from the center of the primary exactly three of his diameters, and the outermost five: the former revolves in the space of ten hours, and the latter in twenty-one and a half, so that the squares of their periodical times are very near in the same proportion with the cubes of their distances from the center of Mars; which evidently shows them to be governed by the same Law of Gravitation that influences the other heavenly bodies.
Jonathan SwiftI can discover no political evil in suffering bullies, sharpers, and rakes, to rid the world of each other by a method of their own; where the law hath not been able to find an expedient.
