Weems & Plath Stormglass Barometer

This is the stormglass, a mysterious device used to predict weather since 1750, employed by Admiral FitzRoy, captain of the H.M.S. Beagle, when he and his lieutenant, Charles Darwin, voyaged to the coast of South America and the Galapagos Islands in 1831 to conduct a hydrographic survey for commerce and naval expeditions for the British Royal Navy.

Although how it functions remains a mystery, the stormglass' ability to predict atmospheric change is well documented. One theory states that the stormglass responds to electromagnetic fluctuations caused by weather and solar storms.

The contained liquid, a mixture of distilled water, potassium nitrate, ammonium chloride, alcohol, and camphor, appears cloudy when precipitation is approaching; when crystals are visible in the liquid, humid or foggy weather can be expected; a cloudy glass with small stars indicates thunderstorms. The hermetically-sealed glass chamber is housed in a handcrafted brass cylinder.
