The mean diurnal motion

From the above mean motions are deduced the following 

 revolutions :

 mean astronomical, solar, or tro- 

 pical year - - - . 365 5 48 51*58732 



The sun's mean revolution in 

 respect to the fixed stars, or the 

 mean sidereal year ; (supposing 

 the mean annual precession 50'* 1) 365 6 9 11*49648 



The sun's mean revolution in 

 respect to the perigee, or the 

 mean anomalistic year - - 365 6 13 58*074 



The entire revolution of the sun's perigee, in 

 respect to the equinox, is therefore 7645793 

 days, nearly, or 209 Gregorian centuries and 

 about 33 years. 



Since the progressive mean motion of the 

 perigee in one year, in respect to the fixed 

 stars, is only U"*7693188, the sidereal revo-
