Thermometer

Description
This mercury-in-glass thermometer has a bend in the stem that accommodates a rolled piece of paper on which is written, in ink: “Thermometer nach Réaumur & Fahrenheit.” The left side of the scale extends from -32 to +55, graduated by degrees Réaumur, with “E.P.” (German for ice point) at zero; the right side extends from -40 to +150, graduated every two degrees Fahrenheit. The whole is enclosed in an outer glass casing. It came to the Smithsonian from the U.S. Military Academy.
