@rahmstorf I wanna know about the bucket sea-gauge

@davidho @rahmstorf

Stephen Hales (1677–1761) June 8, 1751, Philosophical Transactions

The sea-gage β€œwas a common household pail or bucket, with two heads in it; which heads had each a round hole in the middle, near four inches diameter, which were cover'd with valves which open'd upwards; and that they might both open and shut together.” The water temperature was measured on board with a mercury thermometer.
