Consequences of the preceding De∣monstration.
The first Consequence belongs to Astronomy and the Phenomena of the Planets. For first of all, there being no such thing as a Vortex, the Moon turns no longer round the Earth, since, accord∣ing to M. Descartes, the only reason of her cir∣cuiting is the Vortex that carries her aloft. Se∣condly the four Satellites of Iupiter, must be cashier'd of their Dignity and Employment, which they only injoy on account of the conti∣nual Centry they keep about him, and that by means of a particular Vortex attributed to that Planet, as well as to the Earth, in the grand Vor∣tex of the Sun. For all that we have said of the Vortex of the Earth and of the Moon, ought to be apply'd to Iupiter and his garde du Corps.
These two Particulars in Astronomy are consi∣derable enough to assure us that the World of M. Descartes is not that of Gods own making, which we live in, but of a very different Archi∣tecture and Contrivance.
The second Consequence respects almost all the principal Phenomena's of the lower World in general, whereof wee'l only concern our selves with the most considerable and easiest to be un∣derstood. 'Tis by the means only of the Vortex of the Earth, that the Cartesians, following their Master, explain the gravity of Bodies, and ac∣count for the Motion which they have towards the Centre of the Earth. For to instance, say they, when you cast a Stone up in the Air, it forces below it a Mass of the second Element, and Air equal to its bulk: But that same Mass has a far
