Explanation of the Table.—

 

Principle.—The reason why Ferguson’s Tables will not give the true approximate time of the ☽’s Quarters, is, because the Excentricity of the lunar orbit at the Syzygies, is always greater than at the Quadratures.—This hint will be sufficient to explain the Principle, and for further improving the Table.—

 

Practice.—In finding the ☽’s Quarters, proceed as in finding the Change and Full, according to Ferguson, only the 2d Equation must be taken from this Table instead of Ferguson’s 2d Equation,—
