    The earth, therefore, is furrounded every where by this rether to a very great diftance, in confequence of which the air and all bodies in it gravitate towards the earth, and towards each other, agreeably to the appear¬ ances at the furface of it. This aether likewife pervades the pores of all bodies, and lies hid in them : and whilft the bodies with this fluid in them are left to themfelves, (undifturbed by any external violence) this fluid from its elaftic nature con¬ forms itfelf, as to its degree of denfity, to the particular make of that body it is in, e. gr, It is not fo denfe in denfe bodies, as in rare ones. Whence it feems to follow, that every body we have it in our power to make any experiment upon, has na¬ turally within it (before it is difturbed by our experi¬ ment) one certain quantity of this fluid, in fuch a ftate of rarity or denfity, as is moft agreeable to the nature of each particular body. And hence it feems reafonable to conclude, that there will naturally arife fome refiftance to every endeavour, that is made, any how to alter the degree of denfity in the whole of any body, or in any particular part of it. And hence, that it will require fome degree of force to alter the natural quantity of this fluid contained in every particular body; and more or lefs force according to the nature, and make of each. Now, as it is univerfally agreed among thofe, who are moft converfant with eledtrical experiments, that the appearances, which occur in thofe experiments, arife from
