244. When I mention monstrosities I include numerous other apparent defects besides. We are acquainted with hardly anything but the surface of our globe; we scarce penetrate into its interior beyond a few hundred fathoms. That which we find in this crust of the globe appears to be the effect of some great upheavals. It seems that this globe was once on fire, and that the rocks forming the base of this crust of the earth are scoria remaining from a great fusion. In their entrails are found metal and mineral [278] products, which closely resemble those emanating from our furnaces: and the entire sea may be a kind of _oleum per deliquium_, just as tartaric oil forms in a damp place. For when the earth's surface cooled after the great conflagration the moisture that the fire had driven into the air fell back upon the earth, washed its surface and dissolved and absorbed the solid salt that was left in the cinders, finally filling up this great cavity in the surface of our globe, to form the ocean filled with salt water. 245. But, after the fire, one must conclude that earth and water made ravages no less. It may be that the crust formed by the cooling, having below it great cavities, fell in, so that we live only on ruins, as among others Thomas Burnet, Chaplain to the late King of Great Britain, aptly observed. Sundry deluges and inundations have left deposits, whereof traces and remains are found which show that the sea was in places that to-day are most remote from it. But these upheavals ceased at last, and the globe assumed the shape that we see. Moses hints at these changes in few words: the separation of light from darkness indicates the melting caused by the fire; and the separation of the moist from the dry marks the effects of inundations. But who does not see that these disorders have served to bring things to the point where they now are, that we owe to them our riches and our comforts, and that through their agency this globe became fit for cultivation by us. These disorders passed into order. The disorders, real or apparent, that we see from afar are sunspots and comets; but we do not know what uses they supply, nor the rules prevailing therein. Time was when the planets were held to be wandering stars: now their motion is found to be regular. Peradventure it is the same with the comets: posterity will know.
