Some strangely like. You may find, for instance, among the sea- weed, here and there, a little black sea-spider, a Nymphon, who has this peculiarity, that possessing no body at all to speak of, he carries his needful stomach in long branches, packed inside his legs. The specimens which you will find will probably be half an inch across the legs. An almost exactly similar Nymphon has been dredged from the depths of the Arctic and Antarctic oceans, nearly two feet across.
You may find also a quaint little shrimp, CAPRELLA, clinging by its hind claws to sea-weed, and waving its gaunt grotesque body to and fro, while it makes mesmeric passes with its large fore claws, - one of the most ridiculous of Nature's many ridiculous forms. Those which you will find will be some quarter of an inch in length; but in the cold area of the North Atlantic, their cousins, it is now found, are nearly three inches long, and perch in like manner, not on sea-weeds, for there are none so deep, but on branching sponges.
These are but two instances out of many of forms which were supposed to be peculiar to shallow shores repeating themselves at vast depths: thus forcing on us strange questions about changes in the distribution and depth of the ancient seas; and forcing us, also, to reconsider the old rules by which rocks were distinguished as deep-sea or shallow-sea deposits according to the fossils found in them.
As for the new forms, and even more important than them, the ancient forms, supposed to have been long extinct, and only known as fossils, till they were lately rediscovered alive in the nether darkness, - for them you must consult Dr. Wyville Thomson's book, and the notices of the "Challenger's" dredgings which appear from time to time in the columns of "Nature;" for want of space forbids my speaking of them here.
But if you have no time to read "The Depths of the Sea," go atleastto the British Museum, or if you be a northern man, to the admirable public museum at Liverpool; ask to be shown the deep-sea forms; and there feast your curiosity and your sense of beauty for an hour. Look at the Crinoids, or stalked star-fishes, the "Lilies of living stone," which swarmed in the ancient seas, in vast variety, and in such numbers that whole beds of limestone are composed of their disjointed fragments; but which have vanished out of our modern seas, we know not why, till, a few years since, almost the only known living species was the exquisite and rare Pentacrinus asteria, from deep water off the Windward Isles of the West Indies.
Of this you will see a specimen or two both at Liverpool and in the British Museum; and near them, probably, specimens of the new-old Crinoids, discovered of late years by Professor Sars, Mr. Gwyn Jeffreys, Dr. Carpenter, Dr. Wyville Thomson, and the other deep- sea disciples of the mythic Glaucus, the fisherman, who, enamoured of the wonders of the sea, plunged into the blue abyss once and for all, and became himself "the blue old man of the sea."Next look at the corals, and Gorgonias, and all the sea-fern tribe of branching polypidoms, and last, but not least, at the glass sponges; first at the Euplectella, or Venus's flower-basket, which lives embedded in the mud of the seas of the Philippines, supported by a glass frill "standing up round it like an Elizabethan ruff." Twenty years ago there was but one specimen in Europe: now you may buy one for a pound in any curiosity shop. I advise you to do so, and to keep - as I have seen done-under a glass case, as a delight to your eyes, one of the most exquisite, both for form and texture, of natural objects.
Then look at the Hyalonemas, or glass-rope ocean floor by a twisted wisp of strong flexible flint needles, somewhat on the principle of a screw-pile. So strange and complicated is their structure, that naturalists for a long while could literally make neither head nor tail of them, as long as they had only Japanese specimens to study, some of which the Japanese dealers had, of malice prepense, stuck upside down into Pholas-borings in stones. Which was top and which bottom; which the thing itself, and which special parasites growingon it;whether it was a sponge, or a zoophyte, or something else; at one time even whether it was natural, or artificial and a make- up, - could not be settled, even till a year or two since. But the discovery of the same, or a similar, species in abundance from the Butt of the Lows down to Setubal on the Portuguese coast, where the deep-water shark fishers call it "sea-whip," has given our savants specimens enough to make up their minds - that they really know little or nothing about it, and probably will never know.
And do not forget, lastly, to ask, whether at Liverpool or at the British Museum, for the Holtenias and their congeners, - hollow sponges built up of glassy spicules, and rooted in the mud by glass hairs, in some cases between two and three feet long, as flexible and graceful as tresses of snow-white silk.
Look at these, and a hundred kindred forms, and then see how nature is not only "maxima in minimis" - greatest in her least, but often "pulcherrima in abditis" - fairest in her most hidden works; and how the Creative Spirit has lavished, as it were, unspeakable artistic skill on lowly-organized creature, never till now beheld by man, and buried, not only in foul mud, but in their own unsightly heap of living jelly.
But so it was from the beginning; - and this planet was not made for man alone. Countless ages before we appeared on earth the depths of the old chalk-ocean teemed with forms as beautiful and perfect as those, their lineal descendants, which the dredge now brings up from the Atlantic sea-floor; and if there were - as my reason tells me that there must have been - final moral causes for their existence, the only ones which we have a right to imagine are these - that all, down to the lowest Rhizopod, might delight themselves, however dimly, in existing; and that the Lord might delight Himself in them.
