These rocks contain the fossiliferous and organic remains of the early and primitive inhabitants of the earth, and indicate the order of man's moral and intellectual development; for as each successive layer or stratum of fossiliferous rocks, in which the organic remains of man are found, marks a distinct period in his history, and the growth of his moral and intellectual brain is found in all cases to correspond to the age and growth of these strata, the question is thus settled and demonstrate! by the facts of geological science. As, the older the rocks, the more remote period they mark in man's history; and, the more remote the period to which it is thus traced, the lower the position in the scale of moral and intellectual development his organic remains prove him to have occupied. The question is thus reduced to a scientific problem, which admits of no disproof or refutation. It is, then, a settled scientific truth, that, the further we trace the past history of man by the footprints of geological science, the nearer he approaches to the condition of an animal,--when he was almost totally devoid of intellectual perceptions and moral feelings, and was consequently a victim to his lusts and animal propensities. Where, then, was his moral purity and perfection, or his angelic holiness? The doctrine is thus shown to be false and fabulous. All the skulls of the primitive races that have been found by geological research show that man, in his first rude type, had scarcely any moral brain; and the history of the race at that period shows that he possessed a correspondingly low, weak, defective moral character, so much so that he could scarcely be considered a moral, accountable being. To talk, then, of his occupying a high moral plane at that early period, is to contradict every principle of science and every page of history. His animal propensities and selfish feelings must have held complete sway over the whole empire of mind for thousands, if not for millions, of years; so that his moral status was but little above that of the brute. The facts of science and history to prove this proposition are abundant; but, as we are compelled to constantly observe the most rigid rules of brevity, we can only find space for one or two proof-illustrations. Human skulls have been found embedded in the rocks of Gibraltar with retreating foreheads, prognathous jaws, and frontal bones an inch thick, and the receptacles for both the moral and intellectual brain very small,--all of which denote very weak moral and intellectual minds, and a preponderance of the animal feelings; and geologists have decided that sixty-five thousand years must have elapsed since those bones and skulls were deposited in those rocks. Hundreds of similar facts have been gathered by geologists, and might be cited: but this one case is amply sufficient, and furnishes as conclusive proof as a thousand could do that the primitive inhabitants of the earth were on a low mental status,
