to be 140', if the equation of the centre is computed for these anomalies, and the intervals tabulated,
we get – 12.9, – 45.6, – 67.7, – 71.6, – 56.3, – 26.0, + 12.9, + 45.6, +67.7, + 71.6, + 56.3,

• 26.0, in minutes. As these are not much different from the series – 11, – 48, – 69 etc., we see
  that our assumption about the apsis is correct and the series – 11, –48, are derivable from it. In the
  two series, the constants are the same in some places, differ by 1' in some, by 2' in some, the differ-
  ence being 3' only in one place. Even this small difference may be due to the constants of the given
  series being empirical, the values having been discovered by repeated observations only. In this
  connection it may be mentioned that the tabular values of the Romaka differ far more than this does
  from the same values obtained
