Pallas and Linné, to give up the old sense-bound fancy, that these corals were vegetables, and their polypes some sort of living flowers. Yet, after all, there are excuses for them. Without our improved microscopes, and while the sciences of comparative anatomy and chemistry were yet infantile, it was difficult to believe what was the truth; and for this simple reason: that, as usual, the truth, when discovered, turned out far more startling and prodigious than the dreams which men had hastily substituted for it; more strange than Ovid’s old story that the coral was soft under the sea, and hardened by exposure to air; than Marsigli’s notion, that the coral-polypes were its flowers; than Dr. Parsons’ contemptuous denial, that these complicated forms could be “the operations of little, poor, helpless, jelly-like animals, and not the work of more sure vegetation;” than Baker the microscopist’s detailed theory of their being produced by the crystallization of the mineral salts in the sea-water, just as he had seen “the particles of mercury and copper in aquafortis assume tree-like forms, or curious delineations of mosses and minute shrubs on slates and stones, owing to the shooting of salts intermixed with mineral particles:”—one smiles at it now: yet these men were no less sensible than we; and if we know better, it is only because other men, and those few and far between, have laboured amid disbelief, ridicule, and error; needing again and again to retrace their steps, and to unlearn more than they learnt, seeming to go backwards when they were really progressing most: and now we have entered into their labours, and find them, as I have just said, more wondrous than all the poetic dreams of a Bonnet or a Darwin. For who, after all, to take a few broad instances (not to enlarge on the great root-wonder of a number of distinct individuals connected by a common life, and forming a seeming plant invariable in each species), would have dreamed of the “bizarreries” which these very zoophytes present in their classification?
