Water level
This is a detail of a water level made in 1774, probably by Louis-Pierre-Florimond Lennel, a scientific instrument maker based in Paris.
The detail shows the inscription on the centre of the level. It reads 'Lennel a la Sphere a Paris 1774'.
The water level may well have been used in the French National Survey, as its leather case carries the official fleur-de-lys stamp. This survey took place throughout the 18th century, but never received sufficient state backing: triangulation work began in 1747, with funding withdrawn in 1756. By 1784 only Brittany was unsurveyed, and this was not completed until well after the French Revolution, in 1818.
