One of two boxed sets of Genaille's rods, 1885: "reglettes multisectrices" and "reglettes multiplicatrices"

Boxed set of 'reglettes multiplicatrices' by Henri Genailles, 1885.There was a revival of interest in Napier's bones in France in the late 19th century when Henri Genaille simplified their use. Instead of having to add the components in a given area, the user simply follows the pointers to multiply or divide. These sets of cards are known as 'Genaille's rods'.
