Regarding the Biblical Deluge as a record of a submergence of a vast region of Eur-Asia and Northern Africa, at least, while no similar catastrophe has been recorded subsequently, it is unquestionable that submergences equally important have occurred again and again in the geological history of our continents, and have been equally destructive of animal life. It is true that most of these are believed to have been of more slow and gradual character than that recorded in Genesis, but in the case of many of them this is a very uncertain inference from the analogy of modern changes; and it is certain that the post-glacial submergence, which closed the era of palæocosmic man and his companion animals, must have been one of the most transient on record. On the other hand, we need not limit the entire duration of the Noachic submergence to the single year whose record has been preserved to us. Local subsidence may have been in progress throughout the later antediluvian age, and the experience of the narrator in Genesis may have related only to its culmination in the central district of human residence. Finally, if man was really a witness of this last great continental submergence, we cannot be too thankful that there were so intelligent witnesses to preserve the record of the event for our information. It is needless, then, to enter into further details, though these are sufficient to fill volumes if desired, in proof of the remarkable convergence of history and geological discovery on the great Flood, which now constitutes one of the most remarkable illustrations of the points of contact of science proceeding on its own methods of investigation and Divine revelation, preserving the records of ancient events otherwise lost or buried under accretions of myth and fancy. I have already endeavoured to show that the earliest race of palæocosmic men, that of Canstadt, very fairly corresponds with what may have been the characteristics of the ruder tribes of Cainites, and that if we regard the Truchère skull as representing the Sethite people, we may suppose the Cro-magnon race to represent the giants, or Nephelim, who sprung from the union of the two pure types. I have also referred to the possibility that the Truchère race, so little known to us as yet, may have been a prot-Iberian people, possessing even before the Flood domestic animals, agriculture, and some of the arts of life, corresponding to what we find in the earliest postdiluvian nations. This is, indeed, implied in the fact that the postdiluvian nations present themselves to us at once with a somewhat advanced condition of the arts, especially in Chaldea and in Egypt. Such possibilities may serve to suggest to speculative archæologists that they cannot safely assume that all antediluvian or palæolithic tribes were barbarous or semi-brutal, or that there was a continuous development of humanity without any diluvial catastrophe. It is also somewhat rash to carry back
