Bath Thermometer

<< >>
This glass thermometer has a red liquid (probably alcohol), a cylindrical bulb, and a bend in the tube above the bulb. A paper marked “Thermomètre de Bains” carries a scale that extends from -35 to +80 Réaumur graduated in degrees, with indications for such things as “Eau Bou” (boiling water) and the coldest temperature at Paris in 1740, 1777, and 1788. The whole is encased in a glass tube. It came to the Smithsonian from the U.S. Military Academy.
