THE NEW WORLD.
IMPORTANT CHANGE.

Accompanying the last No. of this pop
ular Journal. we received in an extra. an
edition of '.Liebig's .4ninsal Chemistry"
1t is done up in a form different from
that heretofore adopted; combining the
advantages Of a Magazine soith taose ofa
newspaper.
After the close of the present volume.
Oh the 9Th of January next, the regular
edition will also assume the same conve-
nient shspe.
The proprietors Of this valuable paper
being the first to establish and carry out
this new enterprise of publishing cheap
editions of popular works for circulation
among the people. they ought to be sus-
'ained by the voice of the public and the
press: and when the incalculable bene-
fits which must be produced by the issue
of ualasable books in every department Of
Literature, are considered, they should
realise vastly increased circulation as
their plan becomes more widely known
and appreciated. They do not wish Or
intend to confine their selections TO works
of fiction, if the people will sustain them
in the publication of the solid and useful.
The price, as all publishers must be a
ware, is but small advance on the actu-
al cost. and it is only by the extent of
their editions, that remuneration is to
be looked for. 4 work which costs from
S. to $3.50 in London, or 81 to $500
in New York, is always given by them
at rate not exceeding 25 cents. And
their editions, being an extra of their reg
ular sheet. possess the advantage. by
decision of the Postmaster General, of
being sent to all parts of the United
States at newspaper postage.
In order to be enabled to issue their
EXTRAS with expedition, they have com
posing-rooms occupying the whole extent
of two floors. twenty-five by forty four
feet each, with stands, cases and type for
fifty to seventy hands; and two double
cylinder Napier presses, driyea by
steam engine, which are kept in constnnt
operation, day and night, through the
week. They have nearly 5000 pounds,
or four tons, Of type, and often have H.
100000 ems standing at the same time.
The number of hands employed by them
in the various departments, is about sixty.
They have now in press, and is by this
time ready for delivery, "Laebig's .AsrS-
cultural Ctemistry''-a work Of inestlma
BILE value to every class Of citizens, but
more especially to farmers and garden
ers. 1t is issued in double No. of the
New World, in beautiful octave form.

be based on an exact acquaintance with
the means of nutrition of vegetables, and
with the influence of soils and action of

we must seek from chemistry, which
teaches the mode of investigating the
