...in consequence of the air being rarefied or driven out by the burning paper, and in consequence of the pressure of the atmosphere upon the surface of the water in the saucer. These experiments show that the atmosphere presses in all directions, upwards, downwards, and... | |

...reservoir at length begins to flow through this duct, and expels the air from it. As soon as this happens, the pressure of the atmosphere upon the surface of the water in the reservoir forces it through the duct, and continues to do so, till the supply being exhausted, and... | |

...sent down by raising the handle of the pump, a quantity of air is removed from the bore or barrel, and the pressure of the atmosphere upon the surface of the water in the well or cistern, into which the lower or open end of the pump is inserted, forces up as much water as supplies... | |

...the suction pipe, and which being removed, the water supplies its place, being impelled thereto by the pressure of the atmosphere upon the surface of the water in the well, until it has attained to the height of about 34 feet. [For further information see article " Pump."]... | |

...between the pump barrel and condenser ; the mode of action is very simple : when the plunger is drawn up, the pressure of the atmosphere upon the surface of the water in the well, forces it up the pipe, A, through the box and valve, H, filling the space below the piston or plunger... | |

...the steam which fills the receiver, so as to cool and condense the steam, and make a vacuum therein. The pressure of the atmosphere upon the surface of the water in the cistern H then causes the water to mount up the perpendicular suction-pipe, through the valve G, towards... | |
