instead of evolving carbonic acid gas�察�as other animals do�察�evolve pure
oxygen。 So�察 �at least�察 �says Liebig�察 �who states that he found a small
piece of matchwood�察�just extinguished�察�burst out again into a flame on
being immersed in the bubbles given out by these living atomies。
I myself should be inclined to doubt that this is the case with
zoophytes�察�having found water in which they were growing ��unless�察 �of
course�察�sea´weeds were present�� to be peculiarly ready to become foul�察�
but it is difficult to say whether this is owing to their deoxygenating the
water while alive�察�like other animals�察�or to the fact that it is very rare to
get a specimen of zoophyte in which a large number of the polypes have
not been killed in the transit home�察�or at least so far knocked about�察�that
��in the Anthozoa�察 �which are far the most abundant�� the polype ´ or rather
living mouth�察�for it is little more ´ is thrown off to decay�察�pending the
growth of a fresh one in the same cell。
But all the sea´weeds�察 �in common with other vegetables�察 �perform
this function continually�察 �and thus maintain the water in which they
grow in a state fit to support animal life。
This fact ´ first advanced by Priestley and Ingenhousz�察 �and though
doubted by the great Ellis�察 �satisfactorily ascertained by Professor
Daubeny�察�Mr。 Ward�察�Dr。 Johnston�察�and Mr。 Warrington ´ gives an answer
to the question�察�which I hope has ere now arisen in the minds of some of
my readers�察 �
How is it possible to see these wonders at home�拭 �Beautiful and
instructive as they may be�察�can they be meant for any but dwellers by the
sea´side�拭 �Nay more�察�even to them�察 �must not the glories of the water´
world be always more momentary than those of the rainbow�察 �a mere Fata
Morgana which breaks up and vanishes before the eyes�拭 �If there were
but some method of making a miniature sea´world for a few days�察�much
more of keeping one with us when far inland。 ´
This desideratum has at last been filled up�察 �and science has shown�察�
as usual�察�that by simply obeying Nature�察�we may conquer her�察�even so
far as to have our miniature sea�察�of artificial salt´water�察 �filled with living
plants and sea´weeds�察�maintaining each other in perfect health�察�and each
following�察�as far as is possible in a confined space�察�its natural habits。

To Dr。 Johnston is due�察 �as far as is known�察 �the honour of the first
accomplishment of this as of a hundred other zoological triumphs。 As
early as 1842�察�he proved to himself the vegetable nature of the common
pink Coralline�察 �which fringes every rock´pool�察 �by keeping it for eight
weeks in unchanged salt´water�察�without any putrefaction ensuing。 The
ground�察�of course�察�on which the proof rested in this case was�察�that if the
coralline were�察�as had often been thought�察�a zoophyte�察�the water would
become corrupt�察 �and poisonous to the life of the small animals in the
same jar�察 �and that its remaining fresh argued that the coralline had re´
oxygenated it from time to time�察 �and was therefore a vegetable。
In 1850�察 �Mr。 Robert Warrington communicated to the Chemical
Society the results of a year's experiments�察 �On the Adjustment of the
Relations between the Animal and Vegetable Kingdoms�察 �by which the
Vital Functions of both are permanently maintained。; The law which
his experiments verified was the same as that on which Mr。 Ward�察 �in
1842�察�founded his invaluable proposal for increasing the purity of the air
in large towns�察�by planting trees and cultivating flowers in rooms�察�THAT
THE ANIMAL AND VEGETABLE RESPIRATIONS MIGHT
COUNTERBALANCE EACH OTHER�察�the animal's blood being purified
by the oxygen given off by the plants�察�the plants fed by the carbonic acid
breathed out by the animals。
On the same principle�察 �Mr。 Warrington first kept�察 �for many months�察�
in a vase of unchanged water�察 �two small gold fish and a plant of
Vallisneria spiralis�察�and two years afterwards began a similar experiment
with sea´water�察�weeds�察�and anemones�察�which were�察�at last�察�as successful
as the former ones。 Mr。 Gosse had�察 �in the meanwhile�察 �with tolerable
success begun a similar method�察 �unaware of what Mr。 Warrington had
done�察 �and now the beautiful and curious exhibition of fresh and salt
water tanks in the Zoological Gardens in London�察�bids fair to be copied
in every similar institution�察 �and we hope in many private houses�察�
throughout the kingdom。
To this subject Mr。 Gosse's book�察 �The Aquarium�察─ �is principally
devoted�察 �though it contains�察 �besides�察 �sketches of coast scenery�察 �in his
usual charming style�察�and descriptions of rare sea´animals�察 �with wise and

goodly reflections thereon。 One great object of interest in the book is
the last chapter�察�which treats fully of the making and stocking these salt´
water ;Aquaria�察─�and the various beautifully coloured plates�察�which are�察�
as it were�察�sketches from the interior of tanks�察�are well fitted to excite the
desire of all readers to possess such gorgeous living pictures�察 �if as
nothing else�察 �still as drawing´room ornaments�察 �flower´gardens which
