OBSERVATION-DISCLOSURES

Even in the present age, when Progress
is emphaticaiIy the watchw0rd of all
arts and sciences alike, few have adyanc-
ed with greater or more rapid strides
than CHEMISTRY, both in the departments
of theory and pra, tice.
1t is now upwards OF twenty years
since a work on ''CHEMIsTRY, AS APPLIED
TO THE ARTS AND MANUFACTURES" edit
ed by the late Dr. Muspratt, was pro-
jected, which represented the state of
knowledge of that day on the most i'm
portant subject The reception which
that work met with, and the great circu-
lation it at once attained, were convincing
proofs that it supplied u want the impor-
lance of which had been keeniy felt; and
even to the present time the demand has
been such as to show that it has taken a
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
ed, by recent discoveries or improved
practice. The notation" itself has not
escaped, having been replaced of late
years bya more modern system.
These facts have convinced the Pub
fishers that a 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 It's well-known predecessor, will
yet 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 Il work
could be adequately treated by no one
| writer, however learned or painstaking,
the assistance of the leading chemists of
| the present day has been secured, as
well as of writers who are practically ac-
quainted with all the details of our great
manufactures; while no expense has been
spared to add to The clearness and use
fulness of the articles by means of copi-
Gus illustration.
| This department of the work will COM
prise, besides very numerous Wood
cuts in the text, a series of highly finish
! cd Plate Englavings of the most import
ant or elaborate manufacturing plans in
use at the present time,-a feature, it is
hoped, which will greatly addto its value
| and interest.
The alphabetical arrangement having
been found best adapted to the require
ments of the case, has 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 unsatiseac
tory and 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.
