Although there are some, indeed, who deny that there are reservoirs of water lying ready provided out of sight, in the places from whence springs flow, and that when they appear, they merely issue and run out; on the contrary, they say, they are then formed and come into existence for the first time, by the liquefaction of the surrounding matter; and that this change is caused by density and cold, when the moist vapor, by being closely pressed together, becomes fluid.
