What is a prognosticator?

A prognosticator is a person who prognosticates or forecasts future events and it is basically just another term for psychics, oracles, sibyls, mystics, crystal gazers and palmists.

Tempest prognosticator

A tempest prognosticator is a 19th century innovation where leeches are stores in a barometer to indicate an upcoming storm. It was invented by George Merryweather in 1851. As to how it works, the leeches inside the barometer will feel agitated when there is an imminent storm and they will climb out of the bottles and trigger a tiny hammer that would strike the bell.

A direct quote from George Merryweather on how his invention works:

“After having arranged this mouse trap contrivance, into each bottle was poured rain water, to the height of an inch and a half; and a leech placed in every bottle, which was to be its future residence; and when influenced by the electromagnetic state of the atmosphere a number of leeches ascended into the tubes; in doing which they dislodged the whalebone and caused the bell to ring.”, George Merryweather.

It was said that it would be hard for the leeches to actually climb out the bottles but it the probability of them getting out is high if they are really motivated by the anticipated storm. The more leeches to have rung the bell, the possibility of an upcoming storm is higher.

It was believed that he tried to convince the government into using his device to predict upcoming storms and use it at the British coastlines, but they said it would be better if they chose Robert FitzRoy’s invention which was called the Storm Glass.
