210. The above theory of anomalies and equations is subject to an important variation in practice, which we alluded to briefly in Sec. 208, but which it is now necessary to dwell on specially. Supposing a mean tithi is accomplished at A days of the solar year, when the Moon's anomaly is B days, then, if the ☉'s equation for A days is —a, this means that the tithi would be accomplished (supposing for the moment that the ☾'s anomaly had no influence) in A—a days of the solar year, at a moment when the moon's anomaly would be B—a. Now we proceed to determine the influence of this moon's anomaly B—a and find the moon's equation to be, let us suppose, —b. We then put down, as the actual ending moment of the tithi, A—a—b days of the solar year.
