49. The mean longitudes of the planets, being 

 determined as by observation at the instant of the 

 commencement of the year, and their mean annual 

 motions, &c. thence deduced, as already explained 

 (§ 12, 13, 14, 15, 16,) we obtain from thence the 

 following revolutions in the cycle of 1080000 years. 



Sun - - - 1080000 



Moon - - 14438323 



Mercury 4484258 



Venus 1755589 



Mars - - - 574209 



Jupiter - - 91053 



Saturn 36646 



Days 394479135 



And, the revolutions of the apsides and nodes in a 

 Calpa, or 4320000000 years, will be as follows:-^ 



Apsides. 

 Sun - - 11985 direct 



Moon - 488114797 ditto 232:^08827 



Mercury - 8014 retro. 340671 



Venus - - 33076 ditto 299081 



Mars - - 28977 direct 286659 



Jupiter - 6751 retro. 315916. 



Saturn - - 24642 direct 297301 



Nodes — retrograde. 



50. The revolutions of the Sun in the cycle = 

 1080000 subtracted from the revolutions of the 

 Moon in the same period = 14438323 leave the 

 number of mean lunations= 13358323, which be- 

 ing multiplied by 30, gives the number of tithis 

 or lunar days =' 400749690 : and 4007496SO — 

 394479135 =6270555, the intercalary lunar days in 

 the cycle. The number of sidereal days, or appar- 

 rent revolutions of the fixed Sars = 394479135 + 

 1080000 = 395559135. The Moon's periodical 

 revolution, or the time in which she goes from the 



first
