Short & Mason Aneroid Barometer

This is a hefty instrument, 5 inches in diameter and 2 inches deep. The face reads: “Surveying Aneroid / COMPENSATED FOR TEMPERATURE / Short & Mason / London / Tycos / Made in England.” The altitude scale around the circumference of the face reads in from sea level to 6000 feet. An inner pressure scale reads from 24.8 to 31 inches of mercury. Both scales can be read by a magnifying lens.
The Taylor Instrument Companies began operating, as such, 1904, introduced the Tycos trade mark in 1908, and gave this instrument to the Smithsonian in 1923.
