This rare Bourdon barometer, crafted by E.H. Paris in the late 19th century, is set within a mahogany case, whose deep, rich wood — measuring 18 centimeters in diameter — creates an exceptional contrast with the instrument’s golden-gleaming mechanism. At the heart of this mechanism is a gracefully curved Bourdon tube, crafted from brass with an oval cross-section. Evacuated of air, this tube expands and contracts in response to atmospheric pressure, beating with the pulse of the device like a living heart.

Through a system of levers, the movement of the tube is transmitted to a finely crafted toothed linkage, elegantly connecting with a gear that drives a blued steel pointer. Encased within a brass niche, the entire mechanism radiates a golden glow, creating an immersive effect of depth and intricacy.

This barometer forgoes a traditional dial, opting instead for a flat glass set into a slender brass bezel. On this glass, a scale in centimeters of mercury, along with standard weather indications in French, has been meticulously reverse-painted, transforming the glass itself into an indicator. The barometer is signed with the name of the French optics brand "Verchaly" from Angers, further underscoring its unique heritage and fine craftsmanship.
