From the Scientific American
The completion OF Knights american
Mechanical Dictionary" is an event in the
annals OF literature IN tins country, rs IL
marks the substantial completion OF a great
and elaborate undertaking, tie 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
work Of this description. Thousands Of pat
ents, American and foreign, have been di
gested, industrial processes of every nature
have been examined and the latest L. prove
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
field of applied science, has been subjected
to careful revision and condensation. and by
means Of ingenicusly contrived systems of
indexing, rendered Invaluable for purposes
of reference and research. Add to this the
iaDors of artist and engraver. and there is
little food for marvel that the work has cost
Sl00 900. that IL treats of 10000 subjects; con-
tains 400 engravings; and that its three vol
umes include 500 pages. 1t is more an en-
cyclopPdia than dictionary; it is. in fac, "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 ofthe
yoIumeS themselves.
The scope ofthis work concerns griculiural
Machinery, Wood, Metal, Glass, Stone. Clay,
Cement, and Leather Working; Mining Hy-
draulic, Railway, Marine, and Military En-
gineering; Working in Cotton, Wool, SilB, 4,
Flax, Hemp, and Paper; Steam, AR. and
Gas Engines, and other Motors; Lighting,
Heating, Drying,and Ventilating; Fine Arts;
Photograph, Electric, Telegraphic, Optical,
Neurological, Calculating, urgical, and Den
tai instruments, etc.
Its value.even If there 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 trustworthiness 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 ofillustratioLs.
Dentists, surgeons, philosophers. chemists
engineers, mechanics, and scientific men and
students ofevery grade. will 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
nnd constant supplementary course of in.
struction SO arranged as 20 be available fol
instant re ierence. The work consists ofthree
handsome octave yolumes.and will be found
an 1nTafuabie book of referaece in the fam
lily, the counting-Toom. and the workshop.
No better educational work could be placed
before children, adapted as IL is to awaken a
latent taste which may have an i'm portant
bearing on their life career.
