Excerpt from Buffon's Natural History of Man, the Globe, and of Quadrupeds, Vol. 1 When the tessute of the atmosphere is removed from the mouth 0 a pipe or tube, water will rise in it to the height of thirty-three feet above the height of its source. This is owing to the pressure of the atmosphere upon the source of the water; and on this principle the common pumps are constructed, a vacuum being created by the raising of the piston of the pump.
