RUBBING OFF STONES PERFECTLY LEVEL,

AND

Equally adapted for every other Material requiring a mathematically level surface,

AT A

Saving of one-third the usual Labour and Time.

This important invention consists of a Metal Disc, mathematically levelled on itsunder surface, on the upper parts of which are quadrangular -perforations, ending in atubular form, which are supplied with sand and water, the same being subjected to arotary motion by the handle, the continuous supply of the sand readily and effectuallyeffaces the subject to be removed.

The Bkeakage op Stoh es so frequently arising, as it does, from the uneven per-formance of the ordinary method of grinding, being for the future avoided by the appli-cation of the Levigator, it is confidently introduced to the Trade as the most importantmachine yet invented ; while, at the same time, it effects a great saving, op time andLaboub, it produces a mathematically level surface, with that ease, that it may he workedreadily by a lad. .

These Machines, the most useful invention yet introduced, have met with the universalapproval of the Lithographic Trade, and have become generally adopted.

Prices—small size, 12in. diameter, 40s. ; large ditto, 15in. diameter, 50s.
