and orange, trnd scarlet atxd white are among the hues that 

 distinguish it. This, and many others l^at might be eimme- 

 rated, are not as easily made to quit their hold on substan ma 

 to which they may be attached ; and, as to injure their organs 

 of adhesion would be to render them worthless, it is better, 

 where it can be accomplished, to ch^ oflF that portion of the 

 stone to which they are anchored. 



Did space permit, much more might be written of the curio- 

 sities of the marine tank. That, however, is not our purpose. 

 The little that has been described may perhaps whet the 

 interest of our readers lucky enough to possess already a well- 

 stocked tank ; or, better still, to determine those who previously 

 were only half resolved to set about the instructive amuse- 

 ment of constructing an aquarium. 



For the benefit of such of our readers who, from prudential 

 motives, may prefer acquiring the art of managing Vhe marine 

 aquarium by easy stages, we wiU. take the liberty of extracting 

 from Mr. Charles Kingsley's " Wonders of the Sea-Shore," the 

 following simple directions : — 



" Buy at any glass-shop a cylindrical glass jar, some six 

 inches in diameter and ten high, which will cost you from thi-ee 

 to four shiUingg. Wash it clean, and M it with clean salt 

 water dipped out of any pool among the rooks, only looking 

 first to see that theire 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. So much for your vase. Now 

 to stock it. Go down at low spring-tide to the nearest ledge 

 of rocks, and with a hammer and chisel chip off a few pieces of 

 stone covered with growing sea-weed. Avoid the common and 

 coarser kinds {Fuci) which cover the surface of the rocks, for 

 they give out under water a sUme which will foul your tank ; 

 but (ioose the more deUcate species which fringe the edges of 

 every pool at low-water mark. The pink coralline, the dark 

 blue, ragged dxdse {Bhodym&ma), the Carrageen m.oaa:(Ohmi' 

 drrue), and, above ail, the delicate green nlva, which you will 

 see growing everywhere in wrinkled fan-shaped sheets, aB thin 

 as the finest silver paper. The smallest bits of stone are suffi- 

 cient, provided the sea- weeds have hold of them ; for they have 

 no real roots, but adhere by a small disc, deriving no nourish- 

 ment from the rock, but only from the water. Take care, 

 meanwhile, that there he as little as possible on the stone 

 beside the weed itself. iEspecially scrape off any small sponges,
