From the Scientific American
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 a 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 nf this description. Thousands of pat
ents, American and foreign, have been di-
gested, industrial processes of every nature
have been examined. and the latest III 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 ingeniously contrived systems of
| incexing, 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
slOO 600: that II treats of 20 600 subjects; con-
tains I. 400 engravings; and that its three vol
| umes include 2 so pages. 1t is more an en-
cyclopoedia than a dictionary; IL is, in fact, a
| mechanical and scientific library, carried up
| to the latest dates. A just estimate of the
| com prehensive 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
voIumes themselves.
The scope ofthis work concernsA Agricultural
Machinery, Wood, Meta, Glass, Stone Clay,
| Cement and Leather Working; Mining, Hy-
| draulic, Railway, Marine, and Military En-
gfneering; Working in Cotton, Wool, SILK.
Flax, Hemp, and Paper; Steam, AR, and
Gas Engines, and other Motors; Lighting.
Heating, Drying. and Ventilating; Fine Arts;
Photographic, Electric, Telegraphic, Optical,
| Neurological, Calculating, surgical, and Den
tai instruments, etc.
OF similar nature, would be very great on
account of IFS scope. its great number OF IL
lustrations, and the trustwOrthtness OF It's
author; but at present its value is enhanced
by the fact that il has. properly speaking, no
competitor. There is published no book oi
similar intent which is at once so large, SO
well illustrated, so closely brought down 10
the present time, and so full oftllustrations
Dentists, surgeons, philosophers, chemists
engineers, ,mechanics,a and scie ntlnc men and
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 alsC
find constant supplementary course OF IN
struction SO arranged as TO be available fo
instant reference. The work consists ofthre'
handsome octave volumes.a and will be foun(
. a n invaluable book of referance in the tam
| ily. the counting-room. and the workshop
: No better educational work could be places
before children, adapted as IL is to awaken
latent taste which may have an imporIan
! bearing on their life career.
