Let az now imagine an immense Nebular maas

Thus the great fact Of the Suns rotation b necss-

ed ON by two tendencies precisely similar 20 those
which regulate the motions OF the planets round the
sun; first, it's tendency to ay away in consequence
of its motion and secondly, the attraction exerted
over il by the whole mass which counterscts this
