Let T, as before, reprefent the Earth ; T S 

 a Right Line, conjoining the Earth and Sun : 

 Let aho the Line T ACB, be drawn to the 

 Place of the amending Node of the Moon, as 

 kbove equated; and let ST A be the Annual 

 Argument of the Node. Take T A from a 

 Scale, and let it be to A B :: as 56 to 3, or 

 as 11 \ to r. Then bhTecl: B A in C, and on 

 C as a Centre, with the Diftance C A, de- 

 fer ibe a Circle, as A F B, and make the Angle 

 B C F, equal to double the Annual Argument 

 of the Node before-found : So fhall the Angle 

 B T F, be the fecond Equation of the afcen 

 ding Node ; which muft be added, when the 

 Node is palling from the Quadrature to a Syzy- 

 gy with the Sun ; and fubdu£ted, when the Node 

 moves from a Syzygy towards a Quadrature. 

 By which means, the true Place of the Node of 

 the Lunar Orbit will be gained : Whence from 

 Tables made afrer the common way, the Moons 

 Latstude, and the J{eduBion of her Orbit to the 

 Ecliptkkj may be computed, fuppoGng the In- 

 clination of the Moon's Orbit to the Ecliprick, 

 to be 4 degrees, 5*9 minutes, 35- feconds, when 

 the Nodes are in Quadrature with the Sun ; and 

 £ degrees, 17 minutes, zo feconds, when they 

 are in the Syzygys. 



And from the Longitude and Latitude thus 

 found, and the given Obliquity of the Eciiptick, 

 degrees , ^9 minutes , the Right Alcen- 

 fion and Declination of the Moon will be 

 found. 



The Horizontal Parallax of the Moon, when 

 fhe is in the Syzygys, at a mean diftance from 

 the Earth, I make to be 57 minutes, go fe- 

 conds, and her Horary Motion, 33 minutes, 3%
