Pocket Aneroid Barometer

The inscriptions on the face of this barometer read “J.W. Queen & Co. PHILADELPHIA” and U.S.G.S. No 197.” The U.S. Geological Survey was established in 1879.
The pressure scale around the circumference of the face of this barometer reads from 17.5 to 31 inches of mercury; the altitude scale reads from zero to 3,000 feet. Despite the inscription, this instrument was probably made in London. James W. Queen & Co., the Philadelphia firm that sold it, referred to it as a Pocket Mountain Aneroid compensated for temperature, with altitude scale to 3000 feet.
