From the Scientific Americana
The completion of Knights american
Mechanical Dictionary" is an event in the
annals OF literature N this country, as ID
marks the substantial completion OF a great
and elaborate undertaking, the labor on
which has extended over period oil elght
years. IL Is difficult to realize how eolossaI
is the task involved in the Preparation OF a
work of this description. Thousands OF pat
ents, American and foreign, have been d.
gested, industrial processes of every nature
have been examined, and the latest Ia prove
ments therein noted. Engineering works,
scientific discoveries and tools OF every craft
have been studied; and finally, all TINS I'M
mense collection, gathered from the whole
| field of applied science, has been sunJecled
| to careful revision and condensation. and by
means Of ingeniously contrived systems OF
| indexing, rendered inTa liable for purposes
| of reference and research. Add to this the
| iaDors of artist and engrayer. and there is
| little food for marvel that the Work has cost
SlOO 000 that IL treats of ~ O0O sulgectsI con
umes Include 2 500 pages. 1t is more an en-
cyclopoedia than dictionary; II Is, In fact,a
mechanical and scientific library, carried up
10 the lstest dates, A Just estimate OF tne
| com mprehensive nature Of the work, aud its
importance to inventors, engineers, and ar
tisans of every class and in all Libraries, ca u
only be gained by careful examination ofthe
volnmes themselves.

Gas Engines and other Motors: Lighting.

Its value even If there were in print Others
OF similar nature, would be very great on
account OF its SCOPE, its great number OF IL
lustrations, and the rustworthiness OF It's
author: but at present its value Is enhanced
by the TACT that IL has. properly speaking, no
competitor. There is published no book ,ol
