...The air thus expanding, according to a well known law of caloric, will grow colder, at the rate of about one degree and a quarter for every hundred yards of its ascent. This decline in its temperature will necessarily be attended with the condensation of its aqueous vapor,... | |

When the air near the surface of the earth becomes more heated or more highly charged with aqueous vapor, which is only fiveeighths of the specific gravity of atmospheric air, its equilibrium is unstable, and up-moving columns or streams will be formed....
