 tendencies of the opposite parts towards the same centre, it follows that the sinuses or receptacles of water in the one half are nearly proportioned in their position and other respects to those of the other. From all which it follows, that in the southern hemisphere there is an uncovered surface of land correspondent, or nearly so, to that which has been discovered in the northern hemisphere.

If any one should say in opposition to the above argument, that the Psalmist appears to assert that the hemisphere opposite to the northern was entirely covered with water, when he says: "Who stretcheth out the earth above the waters, for His mercy endureth for ever;"—in which the real meaning of the royal prophet would seem to be, that that half of the earth which is between the equinoctial and the Arctic pole was that which was peopled, and that, as by a miracle, all the earth was stretched out above the waters, which covered the other half as far as the Antarctic pole—the answer is, that the Psalmist does not intend to say absolutely that the earth is stretched out above the waters; for that is impossible, since these two bodies, earth and water, gravitate towards the centre of gravity, which is that of the mass or sphere of land and water, and thus of necessity the water upon the earth is contained in its hollows; but, as by an allegory, he said that it might seem to those who inhabit the one hemisphere, that the land was stretched upon the waters which extended towards the other hemisphere, as it is our custom in imagination to think that the antipodes are below those to whom they are antipodes, it being in conformity to the law of gravitation that both one and the other are alike uppermost, and the lower part, which is the centre of gravity, towards which both incline, is common to all.

And thus, in agreement with this, the same prophet, speaking of the divine foundation of the earth, says also in another place: "Who hath founded the earth upon its own stability, that it shall not be moved for ever;" which was as much as
