Wall barometer-thermometer ca. 1760 Clockmaker: Lange de Bourbon The dial of the thermometer is signed by the barometer maker Lange de Bourbon, about whom little is known. He signed other barometers of the period, including one of about 1770 in the Metropolitan Museum, where the dial reads: LANGE DE BOURBON, FAISEUR DE BAROMETRE DU ROY.1The thermometer is on the Réaumer scale (where water freezes at 0° and boils at 80°), which prevailed in France in the second half of the eighteenth century. The dates on the dial record several extremes of temperature in Paris, from a high of 32° Re in 1753 to a low of -15° Re in 1709. Three other cities are included for their low temperatures: Astrakhan, "Petersbour" (modern day Saint Petersburg), and "Kebec" (Quebec), which reached -33 Re in 1743. The latest date on the dial is 1754. Among other such inscriptions are "Chaleur d'un Malade" and "Chaleur de Versoies" (indicating the temperature at which silkworms were raised).
