On page 86, middle column, lines 9–12 under the subheading Ellipsoid Theoretical Gravity, the wrong values appear. “k = 0.001931851353 (a dimensionless coefficient), and e2 = 0.0066938002290 (a dimensionless coefficient).” should be “k = 0.00193185138639 (a dimensionless coefficient) and e2 = 0.00669437999013 (a dimensionless coefficient).”
