notes: label: Description
content: The sextant belonged to the University of Pittsburgh, a school that began as the Pittsburgh Academy in 1787. The frame is brass. The silvered scale is graduated every 15 minutes from -3° to +143° and read by vernier with tangent screw and swinging magnifier to 15 seconds of arc. The inscription on the arc reads "Chapman London." There were several instrument makers and dealers named Chapman working in London during the middle decades of the 19th century. The trade card in the wooden box is that of Benjamin Pike, Jr., who was in business as an instrument dealer in New York from 1843 to 1864 and who probably imported this sextant into the U.S.
