Paper, 'An account of experiments touching the keeping of fishes in water under different circumstances' by Francis Hauksbee Hauksbee writes: 'The fishes made use of in the following Experiments were Gudgeons; which are a sort of Fish very brisk and lively in the Water, and will live a pretty considerable time out of it. Three of them I put into a Glass Vessel, to about three Pints of common Water (which fishes were to be a standard to compare the others by.) Into another Glass, to a like quantity of Water, I put three more of them, which quantity of Water fill’d this Glass to the very Brim and upon which I screw'd down a Brass Plate with a Leather between, to prevent a Communication with the Water in the Glass and the External Air: And that it might the better resemble a Pond of of Water frozen over (on which account this Experiment was made) I suffer’d as little Air as possible to remain on the Surface of the included Water. The third Glass had a like quantity of Water put into it as the former; which Water, first by boyling, then by continuing it a whole Night in Vacuo on the Air Pump, was purg’d of its Air to the greatest nicety: Into this Water also, I put a like number of Gudgeons as into the other.'
