From the Scientific Americana
The completion of knights "AmerIcau
Mechanical Dictionary" is an event in the
annals OF literature an Tins country, as IL
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 10 realize how colossal
is the task involved in the preparation o. Il
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 improve
nents 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
means OF ingeniously contriyed systems of
indexIng, rendered iHvainable for PurPose-
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
slOO 900: that IL treats of 20,ooO subjects; con-
tains Z 400 engravings; and that its three vol
umeS include . 500 pages. 1t is more an en-
cycIopnedia than dictionary; il is, in fact a
mechanical and scientific library, carried mp
TO the latest dates. A just estimate of the
comprehensive nature OF the work, and its
Importance to inventors, engineers, and ar
tisaus of every class and in all libraries, can
OHly be gained by careful examination Oithe
YoIumes themselves.

its values even If there were in print others
of a similar nature, would be very great on
account of IFS scope. Its great number OF IL
Illustrations, and the trustworthiness OF its
author; but at present its value Is enhanced

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.
