Siphon barometer mounted on a green-varnished wooden board adorned with gilt wood carvings. The instrument is protected by two doors. The upper (and larger) door is fitted with a glass window; the lower (and smaller) door hides the tube bulbs. The barometric tube is slightly tilted. The barometric scales, the captions in various languages, and the elegant zodiac signs are printed on paper. Next to the barometer is an alcohol thermometer surmounted by the inscription "Thermometrum Academiae Florentinae." Two recording pointers slide along a pair of vertical metal wires. The instrument, similar to barometers inv. 1142 and inv. 1141, is signed by Giovanni Domenico Tamburini, about whom we have no information.
