Description:

This instrument consists of two mercury-in-glass thermometers mounted on an aluminum frame that is marked "H. J. GREEN B'KLYN N.Y." and "No. 147 SIGNAL CORPS. U.S. ARMY" and equipped with a wooden handle. Each thermometer has a milk white back and a clear front that is graduated every degree Fahrenheit. On one the scale runs from -40 to +137; on the other, it runs from -38 to +122. This was made between 1890 (when Green moved his business to Brooklyn) and 1923 (when the instrument came to the Smithsonian).
