Aneroid Barometer


This is a small brass instrument with two scales around the circumference of its silvered dial. One extends from 18 to 31 inches of mercury, with subdivisions to 20th of an inch; the other extends from zero to 15,000 feet elevation. The back is engraved “No 24 U.S.G.S.”

The mahogany box holding the barometer has two labels. One reads “H.W. Turner, U.S. Geol. Survey, San Francisco” and the other reads “A. LIETZ & CO. OPTICIANS, SAN FRANCISCO.” The former refers to Henry Ward Turner, a mining engineer and geologist who worked for the U.S. Geological Survey from 1882-1901. The latter refers to the California firm that sold a wide range of mathematical and optical instruments. The barometer was probably made in England. The Geological Survey transferred it to the Smithsonian in 1907.
