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

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 geologist, in those tables of stone which form his records, finds no examples of dynasties once passed away again returning. There has no repetition of the dynasty of the fish, of the reptile, of the mammal. The dynasty of the future is to have glorified man for its inhabitant; but it is to be the dynasty-"the kingdom"-not of glorified man made in the image of God, but of God himself in the form man.

That special substance according to whose mass and degree of development all the creatures of this world take rank in the scale of creation, is not bone, but brain.

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 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.
