Atop the scroll pediment sits a resplendent brass medallion finial, intricately adorned with the commanding visage of a lion’s head — a symbol of strength and nobility.

Enhancing its utility and allure, the barometer case hosts an array of additional instruments. A hygrometer, poised to measure atmospheric moisture, balances the composition alongside a spirit level for precise alignment. The alcohol thermometer, with its dual scales in Fahrenheit and Réaumur, is accompanied by finely inscribed textual heat indicators, adding a layer of functional elegance. Each of these elements seamlessly integrates into the overall design, showcasing both beauty and practicality.

A polished brass knob on the front invites interaction, allowing the user to adjust the brass trend pointer with a sense of tactile satisfaction. Meanwhile, the steel indicating hand, dramatically blackened and adorned with a bold crescent-shaped fletching, commands attention as it glides across the dial. Encased under a convex glass lens, the dial is further framed by a gleaming brass bezel, completing this masterpiece with a final touch of refinement.
