Lost and found: The Nooth apparatus.

John Mervin Nooth, military surgeon, correspondent of Joseph Priestly and Benjamin Franklin, and noted inventor and scientist has been lost and found several times, through his eponymous invention: the Nooth apparatus. A large glass apparatus superficially resembling a Kipp's gas generator was used originally for carbonating water during the "fizzy water" craze in the eighteenth century, only to be outdone by one Mr. Schweppes.
