J. Green Thermometer

This small mercury-in-glass thermometer is mounted on a flat ivory plate that is marked "J. GREEN N.Y." and graduated every degree [Fahrenheit?] from +185 to +245. There are no graduations or marks on the stem. It was made between 1849 (when James Green began in business in New York) and 1879 (when he took his nephew into partnership and began trading as J. & H. J. Green). It came to the Smithsonian from the U.S. Military Academy.
