These English barometers are all known as Coastal Barometers. They were made by several British makers, based upon the weather predicting "Rules for Foretelling The Weather" devised by Admiral Fitzroy, known for his association with Charles Darwin, and his surveys aboard HMS Beagle.

These particular barometers are becoming increasingly scarce, in common with barometers of all types.

ADMIRAL FITZROY'S RULES FOR FORETELLING THE WEATHER. Rising Barometer "Rapid" rise indicates unsettled weather. "Gradual" rise indicates settled weather. "Rise", with dry air, and cold increasing in summer, indicates wind from northward, and if rain has fallen, better weather is to be expected. "Rise", with moist air and low temperature, indicates wind and rain from northward. "Rise", with southerly wind, indicates fine weather. Steady Barometer With dry air and a seasonable temperature, indicates a continuance of very fine weather. Falling Barometer "Rapid" fall indicates stormy weather. "Rapid" fall, with westerly wind, indicates stormy weather from northward. "Fall", with a northerly wind, indicates storm, with rain and hail in summer, and snow in winter. "Fall", with increased moisture in the air, and the heat increasing, indicates wind and rain from southward. "Fall", with dry air, and cold increasing (in winter), indicates snow. "Fall", after very calm and warm weather, indicates rain with squally weather. LONDON, 1854
