[79]. When the Sun’s Anomaly is 0 signs 0 degrees, or 6 signs 0 degrees, neither the Sun nor the Moon’s Anomaly have any Equation; which is the case in this Example.

[81]. Babylon is 42 deg. 46 min. east from the Meridian of London, which is equal to 2 hours 51 min. of time nearly. See § [220].
[82]. Our Saviour was born in a leap-year, and therefore every fourth year both before and after is a leap-year in the Old Stile: but the Tables begin with the year next after that of his birth.
[83]. When only one of the Nodes is mentioned, it is the Ascending Node that is meant, to which the Descending Node is exactly opposite.
[84]. When the Moon is North of the Ecliptic and going farther from it, her Latitude or Declination from the Ecliptic is called North Ascending: when she is North of the Ecliptic and going toward it, her Latitude is North Descending: when she is South of the Ecliptic and going farther from it, her Latitude is South Descending: and lastly, when she is South of the Ecliptic and going toward it, her Latitude is South Ascending.

[86]. M. Maupertuis, in his dissertation on the figures of the Celestial Bodies (p. 61-63) is of opinion that some Stars, by their prodigious quick rotations on their Axes, may not only assume the figures of oblate spheroids, but that by the great centrifugal force, arising from such rotations, they may become of the figures of mill-stones; or be reduced to flat circular planes, so thin as to be quite invisible when their edges are turned towards us; as Saturn’s Ring is in such positions. But when very excentric Planets or Comets go round any flat Star, in Orbits much inclined to it’s Equator, the attraction of the Planets or Comets in their perihelions must alter the inclination of the Star; on which account it will appear more or less large and luminous as it’s broad side is more or less turned towards us. And thus he imagines we may account for the apparent changes of magnitude and lustre in those Stars, and likewise for their appearing and disappearing.
