Le régulateur universel is a set of tables for calculating the metric equivalents of old units of length, weight, area, capacity and currency, and for calculating interest, accompanied by small rectangles of card. When a card is laid over the table, the conversion is read through the aperture. The first edition appears to be the one printed in 1807 as Le parfait régulateur of which a copy was sold in these rooms on 13 May 1980 (Honeyman Collection, lot 2163, with a regulator made of brass; see lot 549/iv).
