A brass plate on the frame is marked "H. J. GREEN B'KLYN N.Y." and "No. 8 U.S. WEATHER BUREAU" and graduated every 5 degrees Fahrenheit from -20 to +170. The glass thermometer inside the frame is filled with mercury and alcohol. The back of the stem is milk glass. The clear front is marked "U.S. 8" and graduated every degree Fahrenheit from -20 to +180. The Weather Bureau transferred it to the Smithsonian in 1954.
