Spectrometer

Description
This is a substantial brass instrument on a sturdy black iron base that could be used as a spectrometer or a goniometer. The horizontal circle is 15 cm diameter, graduated on silver to 1’ and read by verniers and microscopes to 20” of arc. The heavy flint glass prism has been lost.
