You may perceive, my Lord, by infpeding the 
Tables which contain the Obfervations of a. Cafflo - 
pe<c and n Ur fa Major is; that the greateft Differences 
that occur therein may be diminifhed, by fuppoftng 
the true Pole of the Equator to move round the 
Point c P t in an Ellipjis, inftead of a Circle. For if 
the tranfverfe Axis, lying in the Diredion AC , be 
1 8", and the Conjugate, as DB , be about 16"; the 
Equations, refulting from fuch an Hypothecs, will 
make the Numbers in the laft Columns agree with 
each other, nearer than as they now ftand. But 
fince this would = not entirely remove the Inequa- 
lities, in all the Portions of the Moon’s Nodes ; I 
fhall refer the more accurate Determination of the 
Locus of the true Pole to Theory ; and at prefent 
only give the Equations for the Prcceilion of the 
Equinoctial Points, and the Obliquity of the Eclip- 
tic, as alfo the real Quantity of the annual Precef- 
fion, to every 5 th Degree of the Place of the Moon's 
Afcending Node, in the following Tables > juft as
