Notes on the Presence and Actions of Air Bubbles in Water

Erasmus Darwin's notes on the presence and behaviour of air bubbles in water. The notes consist of observations of bubbles in freshly drawn water, and of bubble formation whilst pouring a glass of beer; and comments on Dr Benjamin Thompson's experiment into immersing silk in water, Dr Ingenhouse's [Dr Jan Ingenhousz?] experiments with vegetable leaves, and Dr Franklin's experiments with a cut cork dipped in oil.

Darwin proposes an experiment using a metallic plate cut into the form of a longitudinal section of a glass, with an insulated tail which is to be supplied with electricity. A candle would be held above the plate to see if the air bubbles would emerge from the point of the metallic device, extinguishing the flame.
