   Admiral Fitzroy (1805-1865), as commander of HMS Beagle, participated in the Darwin Expedition from 1834-1836. In addition to his naval career, Fitzroy did pioneer work in the field of meteorology. The Beagle's instrumentation for the Darwin Expedition included several chronometers as well as barometers, which Fitzroy used for weather forecasting. The Darwin Expedition also was the first voyage under sailing orders that the Beaufort wind scale be used for wind observations. 

   It consists of a sealed glass bottle containing a mixture of chemicals that undergo interesting and unusual crystal growth in response to changing weather conditions.

  How to Predict the Weather:

• If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter
• If there are threads near the top, it will be warm or windy
• If the liquid contains small stars on a sunny winter day, then snow is coming
• If there are crystals at the bottom, this indicates frost
• A cloudy glass with small stars indicates thunderstorms
• If the liquid is clear, the weather will be bright and clear
