have been examined and the latest ih prove
ments therein noted. Engineering works,
scientific discoveries, and tools OF every craft
have been studied; and finally, all this Inn
mense collection, gathered from the whole
field of applied science, has been subjected
to careful revision and condensation, and, by
indexing, rendered invaluable for purposes
Of reference and research. Add TO this the
