All geologic history is full of the beginning and the ends of species-of their first and last days; but it exhibits no genealogies of development.

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.

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.

Life itself is a school, and Nature always a fresh study.

The footprint of the savage traced in the sand is sufficient to attest the presence of man to the atheist who will not recognize God, whose hand is impressed upon the entire universe.

Poets need be in no degree jealous of the geologists. The stony science, with buried creations for its domains, and half an eternity charged with its annals, possesses its realms of dim and shadowy fields, in which troops of fancies already walk like disembodied ghosts in the old fields of Elysium, and which bid fair to be quite dark and uncertain enough for all the purposes of poesy for centuries to come.
