GENERAL PROSPECTUS.

Even in the present age, when Progress
is cmphatically The watChword of all
arts and sciences alike, few have advanc-
ed with greater or more rapid strides
than CHEMISTRY. h0th in the departments
of theory and pra ticc.
1t is now upwards Of twenty years
since IL work on "CHEMisTRY, AS APPLIED
To THE ARTS AND MANUFACTURERS edit
ed by the late DR.. Muspratt, was pro-
jected, which represented the state of
knowledge of that hay on the most inn
portant subject. The reception which
that work met with. and the great circu-
lation it at once attained, were convincing
proofs that j, supplied a want the impor-
lance of which had been keenly felt; and
even to the present time the demand has
been such us to show that it has taken Il
place il the first rank of our industrial
literature.
Twenty years, however, have made
stupenduous changes in our chemical in
dustries. Not few have sprung into
existence, and now occupy positions of
the greatest importance, which were not
even dreamed of at that time, while of
the rest there are few that have not been
greatly changed, or even wholly remodel
cd by recent discoveries OF improved

escaped, having been replaced of late
years by more modern system.
These facts have convinced the Pub
fishers that Il want exists at the present
time for Work which should embrace
alike the latest scientific knowledge, and
the most recent practical inventions aud
appliances in this great department of
industry To meet this want the present
work has been undertaken, which, it is
hoped, will be found fully to satisfy these
conditions. Its plan, formed on the
model Of Its well-known predecessor, will
vet include such novel features as are
likely to make it even more convenient
and valuable.
Convinced that the infinite variety of
subjects now embraced in such work
could be adequately treated by no one
writer, however learned or piinstaking
the assistance of the leading chemists of
the present day has been secured, as
well rs of writers who are practically ac-
quaintcd with all the details of our great
manufactures: while no expense has been
spared to add to the clearness and use
fitness of the articles by means of cupi-
Gus illustration.
This department of the work will com
pri"~, besides very numerous Wood
ci the text, series OF highly-finlsh-
cd P.a7e Engravings of the most import
ant or elaborate manufacturing plans in
use at the present time,-a feature. it is
hoped, which will greatly add to its value
and interest.
The alphabetical arrangement having
been found best adapted to the require
ments of the case, Ii; S been adopted, and
will be supplemented by copious index,
by which reference can be made to many
subjects Of minor Importance which are
treated in the course of the larger articles
The aim will be throughout to make
each article full and reliable treatise,
and to avoid the error, so common in
dictionary articles, of making a large
proportion mere passing notices, than
which nothing could be more unsatis.ac
tory ard disappointing to the practical
inquirer BY careful attention to these
principles, it is hoped that the present
work will be made worthy alike Of the
reputation of its predecessor, and of the
large and ever growing branch of indus
try it is its aim to represent.
