On the same principle, Mr. Warrington first kept, for many months, in a vase of unchanged water, two small gold fish and a plant of Vallisneria spiralis; and two years afterwards began a similar experiment with sea-water, weeds, and anemones, which were, at last, as successful as the former ones. Mr. Gosse had, in the meanwhile, with tolerable success begun a similar method, unaware of what Mr. Warrington had done; and now the beautiful and curious exhibition of fresh and salt water tanks in the Zoological Gardens in London, bids fair to be copied in every similar institution, and we hope in many private houses, throughout the kingdom.
To this subject Mr. Gosse’s book, “The Aquarium,” is principally devoted, though it contains, besides, sketches of coast scenery, in his usual charming style, and descriptions of rare sea-animals, with wise and goodly reflections thereon. One great object of interest in the book is the last chapter, which treats fully of the making and stocking these salt-water “Aquaria;” and the various beautifully coloured plates, which are, as it were, sketches from the interior of tanks, are well fitted to excite the desire of all readers to possess such gorgeous living pictures, if as nothing else, still as drawing-room ornaments, flower-gardens which never wither, fairy lakes of perpetual calm which no storm blackens,—
οὐτ’ ἐν θέρει, οὐτ’ ἐν ὁπώρῃ.
Those who have never seen one of them can never imagine (and neither Mr. Gosse’s pencil nor my clumsy words can ever describe to them) the gorgeous colouring and the grace and delicacy of form which these subaqueous landscapes exhibit.
As for colouring,—the only bit of colour which I can remember even faintly resembling them (for though Correggio’s Magdalene may rival them in greens and blues, yet even he has no such crimsons and purples) is the Adoration of the Shepherds, by that “prince of colorists”—Palma Vecchio, which hangs on the left-hand side of Lord Ellesmere’s great gallery. But as for the forms,—where shall we see their like? Where, amid miniature forests as fantastic as those of the tropics, animals whose shapes outvie the wildest dreams of the old German ghost painters which cover the walls of the galleries of Brussels or Antwerp? And yet the uncouthest has some quaint beauty of its own, while most—the star-fishes and anemones, for example—are nothing but beauty. The brilliant plates in Mr. Gosse’s “Aquarium” give, after all, but a meagre picture of the reality, as it may be seen in the tank-house at the Zoological Gardens; and as it may be seen also, by anyone who will follow carefully the directions given at the end of his book, stock a glass vase with such common things as he may find in an hour’s search at low tide, and so have an opportunity of seeing how truly Mr. Gosse says, in his valuable preface, that—
“The habits” (and he might well have added, the marvellous beauty) “of animals will never be thoroughly known till they are observed in detail. Nor is it sufficient to mark them with attention now and then; they must be closely watched, their various actions carefully noted, their behaviour under different circumstances, and especially those movements which seem to us mere vagaries, undirected by any suggestible motive or cause, well examined. A rich fruit of result, often new and curious and unexpected, will, I am sure, reward anyone who studies living animals in this way. The most interesting parts, by far, of published Natural History are those minute, but graphic particulars, which have been gathered up by an attentive watching of individual animals.”
Mr. Gosse’s own books, certainly, give proof enough of this. We need only direct the reader to his exquisitely humorous account of the ways and works of a captive soldier-crab, [190] to show them how much there is to be seen, and how full Nature is also of that ludicrous element of which we spoke above. And, indeed, it is in this form of Natural History: not in mere classification, and the finding out of means, and quarrellings as to the first discovery of that beetle or this buttercup,—too common, alas! among mere closet-collectors,—“endless genealogies,” to apply St. Paul’s words by no means irreverently or fancifully, “which do but gender strife;”—not in these pedantries is that moral training to be found, for which we have been lauding the study of Natural History: but in healthful walks and voyages out of doors, and in careful and patient watching of the living animals and plants at home, with an observation sharpened by practice, and a temper calmed by the continual practice of the naturalist’s first virtues—patience and perseverance.
Practical directions for forming an “Aquarium” may be found in Mr. Gosse’s book bearing that name, at pp. 101, 255, et seq.; and those who wish to carry out the notion thoroughly, cannot do better than buy his book, and take their choice of the many different forms of vase, with rockwork, fountains, and other pretty devices which he describes.
But the many, even if they have Mr. Gosse’s book, will be rather inclined to begin with a small attempt; especially as they are probably half sceptical of the possibility of keeping sea-animals inland without changing the water. A few simple directions, therefore, will not come amiss here. They shall be such as anyone can put into practice, who goes down to stay in a lodging-house at the most cockney of watering-places.
Buy at any glass-shop a cylindrical glass jar, some six inches in diameter and ten high, which will cost you from three to four shillings; wash it clean, and fill it with clean salt-water, dipped out of any pool among the rocks, only looking first to see that there is no dead fish or other evil matter in the said pool, and that no stream from the land runs into it. If you choose to take the trouble to dip up the water over a boat’s side, so much the better.
