Since − Ux is the velocity function for the liquid W′ filling the ellipsoid λ = 0, and moving bodily with it, the effective inertia of the liquid in the interspace is
| A0 + B1 + C1 | W′. |
| B0 + C0 − B1 − C1 |
(2)
If the ellipsoid is of revolution, with b = c,
| φ = ½Ux | A + 2B1 | , |
| B0 − B1 |
(3)
and the Stokes’ current function ψ can be written down
| ψ = − ½ Uy2 | B − B1 | ; |
| B0 − B1 |

reducing, when the liquid extends to infinity and B1 = 0, to
