In such case, there would result a correspondingnumber of spheroids; but these would sooner or later co-alesce in one. No two bodiescould continue permanentlyto revolve in one orbit. C. S. Cornelius, in an essayof much originality, has ad-vanced the opinion that theseparated ring would attractto itself some neighboring por-tions of the abandoned nebu-lous spheroid. These portions,he assumes, would join thering- with a smaller rotationalmomentum, and the union of parts thus differing in energyof rotation would strain the ring to such an extent as torupture its continuity. Each of the resulting partial sphe-roids would rotate in the original direction. But the largerof these would eventuallv unite all the others in itself.*.

By some such means repeated a number of times, theentire nebula would be reduced to an assemblage of par-tial nebulous masses, all revolving in orbits about theoriginal centre of gravity.* 2. Rotation of Resulting Mass.—It may be set downas a necessary result that the mass derived from a ring-would possess a rotary motion about some axis. By aninfinity of chances to one, the resultant of all the externalforces acting upon it would not pass through the centre ofgravity. But the mode of connection between the derivedspheroid and the parent mass would be the principal de-terminat
