The completion of Knights American
Mechanical Dictionary" is an event in the
annals OF Literature II tins country, as II
marks the substantial completion OF great
and elaborate undertaking, the labor or
which has extended over a period of eight
years. II is difficult TO realize how colossal
is the task involved in the preparation of q
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 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
dold of applied science. has been subjected
to careful revision and condensation. and by
means Of ingeniously contriyed systems of
indexing, rendered invaluable for purposes
of reference and research. Add to this the
laDors of artist and engraver. and there j.
little food for marvel that the work has cost
500 900: that II treats OF 20 600 subjects; con-
tains 400 engravings; and that Ills three vol
umes include 800 pages 1t Is more an en-
cyclopoedia thar dictionary; it 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 itr
importance to inventors. engineers, and ar
tisans of every class and in all Libraries, can
only be gained by careful examination OF The
voaumes themselves

Its value even ifthere were In print others |
OF similar nature, would be very great on |
account of its scope. its great number of Il. /
lustrations. and the trusiworthiness OF its /
author; but at present its value is enhanced /
by the fact that IL has. properly speat ing no /
competitor. There is published no book of |
similar intent which is at once so large. so |
well illustrated, SO closely brought down % |
the present time. and so full ofIllustrations. |
Dentists, surgeons, philosophers. chemists. |
engineers mechanics ard sciv ntific men and |
students ofevery grade, will find here des- |
cribed and Illustrated more Of the inStru- |
ments and machines peculiar to their pro-
