REQUEST INFORMATION
Barometer-thermometer of vertical form, made of lime wood lacquered and gilded with burnished and amatized leaf. Elegant carvings with purely neoclassical symmetrical decoration such as a waving ribbon knot, laurel leaves, pearl stripes and flowers. A thermometer calibrated according to René Antoine Ferchault de Réamur (1683 - 1757) decorates the upper part in a linear cartouche of pearl stripes. This one is annotated with personal mentions such as references, dated from 1744 to 1765 without forgetting the notation in centigrade of Réaumur. The main part housing the barometer with atmospheric pressure graduated according to Torricelli (1643) and Pascal (1647) is provided with a circular oculi. The latter is decorated with a central wind rose, polychrome flowers and annotated on the periphery with atmospheric variations, such as great rain, variable rain or vt, good weather, fixed weather and very dry. It should be noted that the name and quality of the optician of the time has been partially erased, probably by one of its former owners. On the back, in a cavity provided for this purpose, the mercury bent tube, due to the English physicist S Morland is present and in good condition as well as its pulleys.
