Summary A purely numerical method has been devised for the treatment of Darwin and de Sitter's theory of the figure of a rotating earth in hydrostatic equilibrium. This has been applied to the density distribution suggested by Bullen. De Sitter's numerical constants λ 1 , and K 1 are found to have the values λ 1 =0.00016±0.00018, K 1 = 68 × 10 ‐8 . The ellipticity, on the assumption of hydrostatic equilibrium, is found to be ∈ –1 =297.338 ± 0.050.
