An image formed in his mind, the small sickly creature, all curled up, all its inward motion suddenly stopped.

To control this aberrant inward motion, the leg muscles have to contract but also stretch at the same time.

No surprise there, considering the resemblance between clouds and inward motions of the spirit.

The technique to do this is to lift the leg with the knee going up in an inward motion towards the push leg.

I found what I was feeling about this inward motion to be fascinating.

Meteorologists also hope to be able to "fingerprint" distinctive circulation patterns - like the tightly inward motion of a tornado - to predict the arrival of severe storms.

Firstly the machine was constructed in iron, power was applied to assist the inward motion in 1790 and by 1834 it was fully automatic or self-acting.

The spiral can exhibit outward or inward motion.

This inward (centripetal) motion, however, does not follow a straight (radial) path to the centre; it follows a spiralling, whirling path.

Furthermore, he argues that a man is only moved "by the inward perswasive motions of his spirit".
