A camel's-hair brush, a bent spoon on a long handle, a sponge tied to a
stick, and one or two other instruments which use will suggest, are all
that are needed for keeping the sides of the tank free from growth or
removing obnoxious substances from its bottom.
If, on receiving the animals, any of them should appear exhausted by the
journey, they may sometimes be revived by aerating the water in which they
are by means of a syringe. It should always be remembered, that, though
living in the water, they need a constant supply of air. And it would be
well, in getting an aquarium, to have the tank and the seaweeds sent a few
days in advance of the stock, so that on the arrival of the creatures they
may be at once transferred to their new abode.
There are no American books upon the subject, and, in the present want of
them, the two whose names are given above are the best that can be
obtained. Mr. Gosse's is expensive, costing between four and five dollars.
"The Common Objects of the Seashore," to be got for a quarter of a dollar,
contains much accurate, unpretending, and pleasant information.
_The American Drawing-Book: a Manual for the Amateur, and a Basis of Study
for the Professional Artist_. Especially adapted to the Use of Public and
Private Schools, as well as Home Instruction.
