Octant
notes: label: Description
content: Octant with an ebony frame and reinforced brass index arm. The ivory scale is graduated every 20 minutes from -2° to +104° and read by vernier (without tangent screw) to single minutes of arc. A note written by Capt. H. Flynn of Lowell, Ma. in 1891 traces the history of this octant back to 1772. Stylistic concerns suggest that the instrument was made somewhat later.
