(1) But you are told to your surprise, that however like the dead horny polypidoms which you hold may be, the two species of animal which have formed them are at least as far apart in the scale of creation as a quadruped is from a fish. You see in some Musselburgh dredger's boat the phosphorescent sea-pen (unknown in England), a living feather, of the look and consistency of a cock's comb; or the still stranger sea-rush (VIRGULARIA MIRABILIS), a spine a foot long, with hundreds of rosy flowerets arranged in half-rings round it from end to end; and you are told that these are the congeners of the great stony Venus's fan which hangs in seamen's cottages, brought home from the West Indies. And ere you have done wondering, you hear that all three are congeners of the ugly, shapeless, white "dead man's hand," which you may pick up after a storm on any shore. You have a beautiful madrepore or brain- stone on your mantel-piece, brought home from some Pacific coral-reef. You are to believe that its first cousins are the soft, slimy sea-anemones which you see expanding their living flowers in every rock-pool - bags of sea-water, without a trace of bone or stone. You must believe it; for in science, as in higher matters, he who will walk surely, must "walk by faith and not by sight."These are but a few of the wonders which the classification of marine animals affords; and only drawn from one class of them, though almost as common among every other family of that submarine world whereof Spenser sang -"Oh, what an endless work have I in hand, To count the sea's abundant progeny! Whose fruitful seed far passeth those in land, And also those which won in th' azure sky, For much more earth to tell the stars on high, Albe they endless seem in estimation, Than to recount the sea's posterity; So fertile be the flouds in generation, So huge their numbers, and so numberless their nation."But these few examples will be sufficient to account both for the slow pace at which the knowledge of sea-animals has progressed, and for the allurement which men of the highest attainments have found, and still find, in it. And when to this we add the marvels which meet us at every step in the anatomy and the reproduction of these creatures, and in the chemical and mechanical functions which they fulfil in the great economy of our planet, we cannot wonder at finding that books which treat of them carry with them a certain charm of romance, and feed the play of fancy, and that love of the marvellous which is inherent in man, at the same time that they lead the reader to more solemn and lofty trains of thought, which can find their full satisfaction only in self-forgetful worship, and that hymn of praise which goes up ever from land and sea, as well as from saints and martyrs and the heavenly host, "O all ye works of the Lord, and ye, too, spirits and souls of the righteous, praise Him, and magnify Him for ever!"I have said, that there were excuses for the old contempt of the study of Natural History. I have said, too, it may be hoped, enough to show that contempt to be now ill-founded. But still, there are those who regard it as a mere amusement, and that as a somewhat effeminate one; and think that it can at best help to while away a leisure hour harmlessly, and perhaps usefully, as a substitute for coarser sports, or for the reading of novels. Those, however, who have followed it out, especially on the sea- shore, know better. They can tell from experience, that over and above its accessory charms of pure sea-breezes, and wild rambles by cliff and loch, the study itself has had a weighty moral effect upon their hearts and spirits. There are those who can well understand how the good and wise John Ellis, amid all his philanthropic labours for the good of the West Indies, while he was spending his intellect and fortune inintroducing into our tropic settlements the bread-fruit, the mangosteen, and every plant and seed which he hoped might be useful for medicine, agriculture, and commerce, could yet feel himself justified in devoting large portions of his ever well-spent time to the fighting the battle of the corallines against Parsons and the rest, and even in measuring pens with Linne, the prince of naturalists.
