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.

It is an excellent circumstance that hospitality grows best where it is most needed. In the thick of men it dwindles and disappears, life fruit in the thick of a wood; but where people are planted sparely it blossoms and matures, like apples on a standard or an espalier. It flourishes where the inn and lodging-house cannot exist.

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.

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.

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.

No true geologist holds by the development hypothesis;-it has been resigned to sciolists and smatterers;-and there is but one other alternative. They began to be, through the miracle of creation. From the evidence furnished by these rocks we are shut down either to belief in miracle, or to something else infinitely harder of reception, and as thoroughly unsupported by testimony as it is contrary to experience. Hume is at length answered by the severe truths of the stony science.

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.
