...of the mountains is less than that at the sea-level. To express this result in stricter language., the velocity is directly proportional to the square root of the elasticity of the air ; it is also inversely proportional to the square root of the density of the air. Consequently,... | |

...when this wave shakes the auditory nerve, it produces the sensation of sound. The velocity of sound depends on the elasticity of the air, in relation to its density. It is a mistake to suppose that a body more rapidly transmits sounds in proportion as its density is... | |

...velocity of sound to the clanticity and density of the air, or other medinm, is thus expressed : — " The velocity is directly proportional to the square root of the elasticity of the air, and intently proportional to the square root of the density of the air." The transmission... | |
