...cistern; because the weight of a column of water, about thirty-two or thirty-three feet high, is equal to the weight of a column of air reaching from the surface of the earth to the top of the atmosphere. The pressure of the atmosphere upon the water of the vessel, or cistern, produces this effect. It might... | |

...the Syphon quite emptied of air ; because the weight of a column o£ water 33 feet high is equal to the weight of a column of air reaching from the surface of the earth to the top of the atmosphere. Mercury may be drawn through a Syphon in the same manner as water ; but then the utmost height of the... | |
