I should have sup-posed that water taken from the shore, Avhence the greaterpart of the specimens are procured, would be most likelyto contain those materials which were most suitable for theirsupport. Artificial sea-water is now much used, and theformula for its preparation is given by several authors.But I do not advise the uninitiated to experiment in itscomposition. Aquarium dealers sell tlie necessary powders,mixed in proper proportions, and will give full directionsfor its use. It is evident, however, that the artificial water must beat first totally deficient in one very important element,namely, the animalcules with which water in its naturalstate abounds, and which are necessary for the sustenanceof many marine animals.

INTRODUCTIOX. 13 Plants.Marine Plants for an Aquarium should be taken attachedto the stones or pieces of rock on which they grow. Whenonce the root is detached the plant is dead. The stoneshould be as clear as possible from sponges; and many otherliving incrustations are likely to die, and their decay willprove injurious to the water. Rhytiplil(Eaimiastroides, Coral-Una officinalis, Lelesseria alata, Chondrus crispus, Poly si-phonia, Phi/llophora ruhens (Plate XIII.), Griffithsia, andCallithamnion are recommended for red seaweeds; speciesof Codium, Cycladopliora, Bryopsis, and Viva are suitable forgreens. In ordinary tanks, the green w^eeds are decidedlythe most healthy, but the deep sea tank on trial by Mr.Warrington is partly contrived to encourage tlie growthof reds, which are very pretty objects, to tlie discourage-ment of the greens, which flo
