Hence this revolution is called the earth's diurnal or daily motion ; and it is this revolution of the earth from west to east which produces an apparent motion of the sun, moon, and stars, in a contrary direction. Let us now suppose ourselves to be beings, independent of any planet, travelling in the skies, and looking upon the earth in...
