notes: label: Description
content: This graphometer has telescopic rather than open sights. Its semicircle is graduated to 30 minutes, numbered clockwise and counterclockwise, and read by verniers at either end of the alidade to single minutes. The "LeRebours à Paris" signature refers to Nöel–Jean Lerebours (1761–1840) or his son, Nöel–Marie Paymal Lerebours (1794–1855). Both were prominent instrument makers in Paris. The firm became Lerebours et Secretan in 1845.
