Measuring atmospheric pressure by averaging over an ensemble of leeches

Wikipedia:

The Tempest Prognosticator, also known as the Leech Barometer, is a 19th century invention by George Merryweather in which leeches are used in a barometer. The twelve leeches are kept in small bottles inside the device; when they become agitated by an approaching storm they attempt to climb out of the bottles and trigger a small hammer which strikes a bell. The likelihood of a storm is indicated by the number of times the bell is struck.
