From the Scientific Americana
The completion of Knights American
Mechanical Dictionary" is an event in the
annals OF literature n this 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 TO realize how colossal
Is the task involved in the preparation of a
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 latesti; prove
mentG 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
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
lanoTs of artist and engraver. and there is
little food for marvel that the work has cost
sl0O 900: that 1t treats of 1900 subjects; con-
umes include 2 500 pages. 1t is more all en-
cyclopoedia than a 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
