Edmund Beckett, Encyclopædia Britannica, Ninth Edition (1878)
“ A sidereal day is the interval between two successive transits over the meridian of a place by that imagin ary point in the heavens called T, the first point of Aries, at the intersection of the equator and the ecliptic ; and there is one more sidereal day than there are solar days in a year, since the earth has to turn more than once round iii space before the sun can coma a second time to the meridian, on account of the earth s own motion in its orbit during the day. ”
