It is shown that contrary to former belief an unrelaxed spherical cluster of mass points may rotate without becoming oblate. When used of an unrelaxed system the argument that spherical objects do not rotate is thus false. Some present estimates of the Sun's circular velocity round the galaxy rest on this argument applied to the system of globular clusters.
