[DESCRIPTION: Gauge to delineate the path of the sun, possibly for use with a globe(?). Lines drawn along the edge of a roughly elliptical quadrant. Not by Thomas Jefferson. Nichols gave the same number (N552) to two different drawings, each of which has its own "M" number (N552/M20 and N552/M25). See N552/M25.]
