That the _sun_ is the chief, material, ruling agent, is very clearly revealed; as are some of its chiefest actions on the planets and the rest of the universe. For, in the sun we find a power of melting, dividing and (with the assistance of the air) expanding and sending out the air, first in form of _fire_, and afterwards in that of _light_; which power seems to be so regulated, as to be able to reach the extremities of the universe, where it is _congealed_, _condensed_, and _returned_ back again to the _sun_, to be again _melted_, _divided_, and sent out as before. This action seems to be represented by water in a _still_, for there the fire, forcing its way through the water contained in the _still_, carries off some of the watry particles with it; and when it has reached the head of the _still_, if it has no passage into the outward air, and the _action_ of the fire is not great enough to break the _still_, it is by the coldness of the surrounding air (or as is commonly the case by the coldness of water placed thereon for that purpose) _condensed_ and _returned_ into the water contained in the body of the _still_, there to be _rarified_, _expanded_, and sent off in _steam_, as before. We must suppose the streams of _light_ to be always acting on one side of this terraqueous globe, and there _dividing_, _expanding_ and _rarifying_ the air; the consequence of which must be a kind of _vacuum_, which is immediately filled by the _pressing in_ of the _congealed air_ from the extremities; and as the earth is placed in this fluid of airs, we may as easily conceive that the air pressing in as above, must, with it, turn round the earth, in the same manner, and with as much ease, as water does a common mill-wheel, or the air a wind-mill. By these powers also the terraqueous globe is kept _solid_ and _entire_; for, was this force once taken off, it would soon drop to _atoms_, notwithstanding the pretended _attracting_ power of its materials. To confirm what is here advanced, I shall bring an experiment (which Mr. _Boyle_ has laid down as a paradox) which proves that this terraqueous globe has no _attraction_, nor any _solid_, falling towards it, any _gravitation_; but that all bodies _are forced_ to it by the _incumbent atmosphere_, as much as water is _forced_ up a pump by it (the atmosphere) which, till the time of the great Mr. _Boyle_, was imagined to be performed by, what they called, the _suction_ of the pump. But this is no more than has often happened in philosophy, where when we cannot well account for any thing, we put the _effect for the cause_.
