Glaucus; Or, The Wonders of the Shore

And now, worshipper of final causes and the mere useful in nature, answer but one question,— Why this prodigal variety? All these Nudibranchs live in much the same way: why would not the same mould have done for them all? And why, again, (for we must push the argument a little further,) why have not all the butterflies, at least all who feed on the same plant, the same markings? Of all unfathomable triumphs of design, (we can only express ourselves thus, for honest induction, as Paley so well teaches, allows us to ascribe such results only to the design of some personal will and mind,) what surpasses that by which the scales on a butterfly’s wing are arranged to produce a certain pattern of artistic beauty beyond all painter’s skill? What a waste of power, on any utilitarian theory of nature! And once more, why are those strange microscopic atomies, the Diatomaceæ and Infusoria, which fill every stagnant pool; which fringe every branch of sea-weed; which form banks hundreds of miles long on the Arctic sea-floor, and the strata of whole moorlands; which pervade in millions the mass of every iceberg, and float aloft in countless swarms amid the clouds of the volcanic dust;— why are their tiny shells of flint as fantastically various in their quaint mathematical symmetry, as they are countless beyond the wildest dreams of the Poet?
