This sextant belonged to Bowdoin College in Brunswick, Maine. The frame is brass. The silvered scale is graduated every 10 minutes from -5° to +160° and read by vernier with tangent screw and swinging magnifier to 10 seconds of arc. The serial number is 1170. The "A. Cairns, 12 Waterloo Rd Liverpool" inscription probably refers to Alexander Cairns, an instrument dealer working in Liverpool, England during the third quarter of the 19th century.
