- This tiny mercury-in-glass thermometer is mounted on a silver scale that extends from -20 to +40 degrees, and that is marked "Reaur." The reference is to René Antoine Ferchault de Réaumur, a French scientist who, in 1730, proposed a temperature scale according to which water froze at 0 degrees and boiled at 80 degrees. The thermometer is protected by a black leather case, and was probably designed for a traveler.
