...requires the same time to arrive at it ; and that time bears the same proportion to a sidereal day that the arc of the equator, intercepted between the meridian of the place and the meridian in question, bears to the whole circumference of the equator. And conversely, if we observe... | |

...At the earth's equator the pole is, therefore, in the horizon ; at the pole it is in the zenith. The longitude of a place on the earth is the arc of the equator intercepted between the meridian of that place and that of another place taken as a standard. The observatory of Greenwich is the standard... | |
