From the Scientific Americana
The completion of Knights american
Mechanical Dictionary" is an event in the
annals OF literature IN tins country, as il
marks the substantial completion OF great
and elaborate undertaking, the labor on
which has extended over a period OF eight
years. IL Is difficult to realize how colossal
is the task involved in the preparation of 4
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 il. prove
ments therein noted. Engineering works,
scientific discoveries, and tools OF every crafl
have been studied; and finally, all this int-
mense collection, gathered from the who
field of applied science. has been subjecit d
TO careful revision and condensation, and, ,Ey
means Of ingeniously contrived systems OF
Indexing, rendered invaluable for purposes
of reference and research. Add to this the
laoors of artist and engraver. and there is
little food for marvel that the work has cost
500 00O that IL treats of % 600 subjects; con-
tains 40 engravingS; and that its three vol
umes include $40 pages. IL is more an en-
cyclopoed!a than n dictionary; il 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 10 inventors, engineers, and ar
tisans OF every class and in all libraries, cen
only be gained by careful examination of the
yoIumes themselves.
The scope oftlIis work concerns Agricultural
Machinery, Wood. Metal, Glass, Stone. Clay,
Cement, and Leather Working; Mining. NY
draulic, Railway, Marine, and Military Eu-
gineering; Working in Cotton, Wool, SILK,
Flax, Hemp, and Paper; Steam, AIR. and
Gas Engines, and other Motors; Lighting.
Heating, Drying and Ventilating; Fine Arts;
Photographic, Electric, Telegraphic, optical,
Neurological, Calculating, urgical, and Den
tai instruments, etc.
its value even il there were in print Others
OF n similar nature, would be very great Oh
account of its scope. its great number of IL
lustrations, and she trustworthineSs OF its
auIhor; 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
the present time, and so full OfiilustratiOns.
Dentists, surgeons, philosophers, chemists,
engineers. rS.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
stores and manufactures, and they will also
| find a constant supplementary course of in.
| struction so arranged as to be available for
| instant reference. The work consists ofthree
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
before children, adapted as IL is to awaken n
| latent taste which may have an important
/ bearing on their life career.
