The completion OF Knights American
Mechanical Dictionary" is an event in the
annals OF literature IN thls country, as IL
marks the substantial completion of great
and elaborate undertaking, the labor on
which has extended over period OF eight
years. 1t is difficult 10 realize how colossal
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 in prove
ments therein noted. Engineering works,
sciontific 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
indexing, 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 O0O that il treats of 70, 600 subjects; con-
tains 400 engravings; and that its three vol
umes include 800 pages 1t is more an en-
cyclopuedia thar a dictionary; 1t 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 to inventors, engineers, and ar
tisans of every class and in all libraries, can
only be gained by careful examination of the
voIumes themselves.
The scope ofthis work concerns Agricultural
Machinery Wood, Meta, Glass, Stone. Clay
Cement, and Leather Working; Mlning, ,Hy-
draulic, Railway, Marine, and Military En-
gineering; Working in Cotton, Wool, Silk.

Gas Engines, and other Motors; Lighting.
Heating, Drying and Ventilating; Fine Arts;
Photographic, Electric, Telegraphic, Optical,
Neurological, Calculating, urgical, and Den
tai Instruments, etc.
| Itsvalue, 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 ii 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 ofillustratiOns.
Dentists, surgeons, philosophers. chemists,
| engineers, mechanics and scientific men and
| students ofevery grade, will find here des-
lcribed 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
find constant supplementary course of in.
| struction SO arranged as to be available for
| instant reference. The work consists of three
| 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 Ii is to awaken a
| latent taste which may have an important
bearing on their life career.
