teal use in this country, and have procured almost
every work on tile subject, whether published in
England, France or Germany, the most essential
parts of which being comprised in this Dictionary,
render perfect and comprehensive as possible.
The Publishers have endeavored to use great
economy in type, so that each page of the work
contains at least four times the number of words
found in ordinary pages of the same size. This

Of ample size and clearness, so that mechanic
may construct accurately any machine described.
