Pocket Compass

Description:

The cardinal points of this compass are lettered N, W, S, and O, probably indicating that it was made in Germany. The raised rim is graduated to 15 minutes of time, and numbered counterclockwise, twice, in hours from 1 to 12. One side of the face is graduated to degrees, numbered every 20 degrees from O to N and from O to S. A pendulum clinometer is pivoted at the center. The "Dr F. M. Endlich" inscriptiion is that of Frederic Miller Endlich (1851–1899), a mineralogist at the Smithsonian Institution who served as an assistant on the Hayden geological surveys in the American West in the 1870s.
