Description
This mercury-in-glass thermometer has a bend in the stem that accommodates a white porcelain plate. This plate carries a scale that extends from -23 to +50 degrees, graduated in fifths; it is marked “Celsius” and, at zero degrees, “E.P.” (German for ice point). The whole is enclosed in an outer glass casing with a brass cap. It came to the Smithsonian from the U.S. Military Academy.
