James Green Pocket Aneroid Barometer

The inscription on this barometer reads “James Green / New York / Compensated” and “U.S.G.S. No 60.” It indicates a date of 1879, after the establishment of the U.S. Geological Survey, and before Green took his nephew into partnership and began trading as J. & H. J. Green.
The pressure scale around the circumference of the face reads from 15 to 31 inches of mercury, and the altitude scale reads from zero to 20,000 feet.
