J. Green Mercury Thermometer

Description
This mercury-in-glass thermometer has a cylindrical bulb, mounted on a flat brass plate that is marked "J. GREEN N.Y." and "SIG. SER. U.S.A." and "S 184" and graduated every degree Fahrenheit from -10 to +125. There are no graduations or marks on the stem. It was made between 1870 (when the Signal Service established a national weather service) and 1879 (when James Green took his nephew into partnership and began trading as J. & H. J. Green). It came to the Smithsonian from the U.S. Weather Bureau.
