SP Bel-Art, H-B DURAC Fitzroy Storm Glass, 11" Height (B62000-1400);

Admiral Fitzroy (1805-1865), commander of the HMS Beagle and participant in the Darwin Expedition from 1834-1836, was a pioneer in the field of meteorology. Fitzroy used a storm glass barometer which allowed him to forecast the weather based on changes in the liquid inside the column. If the liquid in the glass was clear, the weather would also be clear. If the liquid was cloudy, the weather would also be cloudy, with the possibility of precipitation. Small dots in the liquid indicated humid or foggy weather conditions. A cloudy glass with small stars indicated thunderstorms. If the liquid contained small stars on sunny winter days, then snow was approaching. If there were large flakes throughout the liquid, it would be overcast in temperate seasons or snowy in the winter. Crystals at the bottom indicated frost. Threads near the top forecasted wind.
