Catalogue Note

A VERY GOOD COPY. The work contains the first description of a mechanical calculating device other than the abacus. In addition to describing the construction and use of Napier's "bones" or rods, it includes two other calculators of his invention: the Promptuary, an example of which was recently identified in the collections of a Madrid museum, and the "chessboard abacus" which, like modern computing machines, is based on the binary number system.
