Description
This sextant, which probably dates from the third quarter of the 19th century, has a brass frame. The inscription on the arc reads "J. & A. Molteni à Paris." The silvered scale is graduated every 10 minutes from -5° to +168° and read by vernier with tangent screw and magnifier to 10 seconds of arc. The Molteni family was in business in Paris from 1782 to about 1900, making a wide variety of mathematical instruments.
