But, in truth, the existing premises, wholly altered by geologic science, are no longer those of Hume. The footprint on the sand — to refer to his happy illustration — does not now stand alone. Instead of one, we see many footprints, each in turn in advance of the print behind it, and on a higher level.

But should we continue to linger amid a scene so featureless and wild, or venture adown some yawning opening into the abyss beneath, where all is fiery and yet dark,-a solitary hell, without suffering or sin,-we would do well to commit ourselves to the guidance of a living poet of the true faculty,-Thomas Aird and see with his eyes.

The sky is full of tokens which speak to the intelligent.

Because science flourishes, must poesy decline? The complaint serves but to betray the weakness of the class who urge it. True, in an age like the present,-considerably more scientific than poetical,-science substitutes for the smaller poetry of fiction, the great poetry of truth.

Nature is a vast tablet, inscribed with signs, each of which has its own significancy, and becomes poetry in the mind when read; and geology is simply the key by which myriads of these signs, hitherto indecipherable, can be unlocked and perused, and thus a new province added to the poetical domain.

The primary rocks, ... I regard as the deposits of a period in which the earth's crust had sufficiently cooled down to permit the existence of a sea, with the necessary denuding agencies,-waves and currents,-and, in consequence, of deposition also; but in which the internal heat acted so near the surface, that whatever was deposited came, matter of course, to be metamorphosed into semi-plutonic forms, that retained only the stratification.

The development doctrines are doing much harm on both sides of the Atlantic, especially among intelligent mechanics, and a class of young men engaged in the subordinate departments of trade and the law. And the harm, thus considerable in amount, must be necessarily more than merely considerable in degree. For it invariably happens, that when persons in these walks become materialists, they become turbulent subjects and bad men.
