points to the Star _R_ at midnight, being then directly opposite to the Sun; and therefore, by the Earth’s diurnal motion the Star comes to the Meridian 12 hours before the Sun. When the Earth is at _H_, the Star comes to the Meridian at 10 in the evening; at _I_ it comes to the Meridian at 8, that is, 16 hours before the Sun; at _K_ 18 hours before him; at _L_ 20 hours; at _M_ 22; and at _A_ equally with the Sun again. A TABLE, shewing how much of the Celestial Equator passes over the Meridian in any part of a mean SOLAR DAY; and how much the FIXED STARS gain upon the mean SOLAR TIME every Day, for a Month. +-----+-----------+-----+------------+-----+------------+ | Time| Motion. | Time| Motion. |Time | Motion. | | | | | | | | +-----+-----------+-----+------------+-----+------------+ |Hours| D.
