Everyone’s favorite Leech Blog, BdellaNea, discusses a leach-powered storm-stracking system on display at the Great Exhibition at London’s Crystal Palace in 1851. “The device required a leech in each of 12 jars. The glass was to be transparent so that the leeches could “see each other” and so agree amongst themselves as to their prognostication. If any leech climbed up and into the escape tube, its weight would dislodge a piece of whalebone, releasing a hammer that would ring the bell thus announcing the onset of inclement weather.”
