In a revolution without rotation, every part of the body moves by an equal amount, while in rotation the motions of the different parts are proportional to their distances from the axis. But revolutions and rotations may be combined. Thus, the planets perform revolutions round the sun, and at the same time rotations about their own axes. es. The moon performs a rotation on its axis in precisely the same time in which it performs a revolution round the earth, to which it consequently always turns the same side. So many nobler bodies to create, Greater so manifold, and on their orbs impose Such restle revolution day by day. Milton , P. L., viii. 3L 3.
