From the Scientific Americana
The completion OF Knights american
Mechanical Dictionary" is an event in the
annals OF literature IN this country, as ii
marks the substantial completion of q great
and elaborate undertaking, the labor on
which has extended over a period of eight
years. 1t is difficult TO realize how colossal
is the task involved in the preparation of a
work Of this description. Thousands of pat.
ents, American and foreign, have been di-
gested, industrial processes of every nature
ments therein noted. Engineering works,
scientific discoveries, and tools OF every craft
have been studied; and finally, all this i'm
mense collection, gathered from the whole
neld of applied science. has been subjected
to careful revision and condensation. and, by
means Of ingeniously contrived systems of
indexing, rendered invaluable for purposes
of reference and research. Add to This the
laDors of artist and engraver. and there is
little food for marvel that the work has cost
sl00, 900: that II treats of 10000 subjects con-
tains 400 engravings; and that its three vol
umes include so pages. 1t is more an en-
cyclopoedia thar dictionary; it is, in fact,a
mechanical and scientific library, carried up
to the latest dates. A just estimate of the
comprehensive nature of the work, and its
importance to inventors, engineers, and ar
tisans of every class and in all libraries, can
only be gained by careful examination OF the
voIumes themselves.
The scope ofthis work concerns A gricultural
Machinery Wood. Metal Glass, Stone. Clay,
Cement, and Leather Working; Mining. Hy-
draulic, Railway, Marine, and Military En-
gineering; Working in Cotton. Wool, SIZE,
FLAX, Hemp, and Paper; Steam, AR. and
Gas Engines. and other Motors; Lighting
Heating, Drying and VentilatiDg; Fine Arts;
Photograph, Electric, Telegraphic, Optical,
Neurological, Calculating, urgical, and Den-
tai Instruments etc.
Itsvalue even ifthere were in print others
OF a similar nature, would be very great on
account of its scope. its great number of IL
lustrations, and the t-ustwOrthineSs OF its
author; but at present its value is enhanced
by the fact that IL has. properly speaking, no
competitor. There is published no book OF
similar intent which is at once so large, so
well illustrated, SO closely brought down 10
/ the present time, and SO full ofillustrations.
Dentists, surgeons, philosophers. chemists.
engineers, mechanics, and scientific men and
students ofevery grade, VIII find here des-
cribed and illustrated more Of the instru-
ments and machines peculiar to their pro-
| fession than can be found in well furnished
stores and manufactures, and they will also
find a constant supplementary course of in
struction SO arranged as to oe available for
instant reference. The work consists of three
handsome octave volumes.and will be found
an Invaluable book of referance in the fam
lily, the counting-roOm. and the WORKSHOP.
No better educational work could be placed
latent taste which may have an important
| bearing on their life career.
