In an air-bubble of moderate dimensions the pressure is very little greater than that of the atmosphere; but, as the difference of pressures within and without a bubble is proportional to its curvature, it appeared to me possible that the so-called solution of air in water might be due in some degree to the extreme compression of the air when divided into small bubbles invisible perhaps even under the microscope.
