This mercury-in-glass thermometer has a cylindrical bulb. A milk white plate carries a scale that ranges from -20 to +360 degrees Centigrade graduated every degree. The back of the plate is marked “72.” The thermometer tube is joined to the plate only at the top. The whole is enclosed in a glass tube. It came to the Smithsonian from the Johns Hopkins University.
