kindred principle of fire, had at an earlier epoch of nature, the same influence and operation on the earth, as water afterwards had; we can well imagine such an influence to have materially affected the lower atmosphere, and to have rendered the climate of the earth, even in the North, totally different from what it is at present. The strata of bones formed by the old flood, and the buried remains of a former race of animals, call forth a remark, which is not without importance in respect to the primitive history of man:--it is, that among the many bones of other large and small land animals, which form of themselves a rich and varied collection of the subterraneous products of nature, the fossile remains of man are scarcely any where to be found. It has sometimes happened that what were at first considered the bones of human giants have been afterwards proved to have been those of animals. It is so very rare an instance to meet in fossile remains with a real human bone, skull, jaw-bone or entire human skeleton (as in one particular instance was found enclosed in a lime-stone, mixed with some few utensils and instruments of the primitive world, such as a stone-knife, a copper axe, an iron club, and a dagger of a very ancient form, together with some human bones); that the very rareness of the exception serves only to confirm the general rule. Were we from this fact immediately to draw the conclusion that during all those revolutions of nature mankind had not yet existence, such an hypothesis would be rash, groundless, completely at variance with history--one to which many even physical objections, too long to detail here, might be opposed. That so very few, and indeed scarcely any human bones are to be found among the fossile remains of the primitive world, may possibly be owing to the circumstance that by the very artificial, hot, and highly seasoned food of men, their bones, from their chemical nature and qualities, are more liable to destruction than those of other animals. I may here repeat what I have already had occasion to remark, and what is here of especial importance, as applying particularly to the history and circumstances of the primitive world;--namely, that all things are not susceptible of an entire, satisfactory, and absolutely certain explanation; and that yet we may form a tolerably correct conception of general facts; though many of the particulars may remain for a time unexplained, or at least not capable of a full explanation. So on the other hand, it would be premature, and little conformable to the grave circumspection of the historian, to reduce all those natural catastrophes (the vouching monuments and mysterious inscriptions of which are now daily disclosed to the eye of Science as she explores the deep sepulchres of the earth)--to reduce, I say, all those natural catastrophes exclusively to the one nearest to the historical times, and which indeed is attested by the clear, unanimous tradition of all, or at
