The life of President Edwards: . d heavy fluid, and filled with lighter in the room of it, or theworld would be overfiowed by a second Deluo-e. There is no other way, therefore, than that this water, when it is in theAbyss, in consequence of pressure, is heavier than earth; but when it isupon the surface, and the pressure is removed, it becomes lighter, as otherwater. And when it returns there again, or the water of the sea in theroom ot It, it becomes as heavy as it was before: which can be no other-wise than by compression. And if water be a body, that is capable of anvcompression by any means, doubtless it is compressed by that prodio-iou^force to which It IS subjected, by the weight of a body, of water, of four ;five hundred miles thickness, incumbent upon it. If we cannot compresswater but very little, or not at all, it is certainly merely for Tnt ofstrength; for all compounded bodies, that have not an absohte pSndeare undoubtedly capable of compression; their particles can be sqSed NOTES ON NATURAL SCIENCE* 747. iiearer together, and closer one among another, if there be but force suffi-cient. Especially is this true of water, which is so rare a body, so muchrarer than many other bodies, whicht yet we know have not a pleni-tude, as gold and quicksilver. I doubt not, therefore, that so great aforce will be enough, sufficiently to compress water. I suppose that noexperiments, that have yet been tried, will prove, but that such a force issufficient to make water five times as dense and specifically heavy, as theearth of this upper shell. And if it be so, it will be enough to support theweight of it; as we see the air here that is compress^!, support manythings that are a thousand times heavier than air would be, had it libertyto expand itself. And seeingthis body of earth is a solid bo-dy, by this means, the surfaceof it may be kept above thesurface of the sea, though light-er than itself; as if quicksilverand oil be put into the samevessel, and a stone thrown in
