Instruction sur les mesures déduites de la grandeur de la terre : uniformes pour toute la République, et sur les calculs relatifs a leur division décimale
A 1793 French government instruction printed at Mâcon by the Commission temporaire des poids et mesures républicaines, setting out the metric weights and measures derived from the earth's size for the whole Republic, with decimal calculation tables. The pictures are plain engraved diagrams: a graduated quadrant, a column of unit conversions, and a circular weight chart with a decorative title page. A designer could take the radiating dial layouts and tidy typeset tables as models for diagrammatic information graphics.
