From out the iron collect in larger throng
And be into the vacuum borne along,
Without the ring itself do follow after.
And this it does, and followeth on until
'Thath reached the stone itself and cleaved to it
By links invisible. Moreover, likewise,
The motion's assisted by a thing of aid
(Whereby the process easier becomes),--
Namely, by this: as soon as rarer grows
That air in front of the ring, and space between
Is emptied more and made a void, forthwith
It happens all the air that lies behind
Conveys it onward, pushing from the rear.
For ever doth the circumambient air
Drub things unmoved, but here it pushes forth
The iron, because upon one side the space
Lies void and thus receives the iron in.
This air, whereof I am reminding thee,
Winding athrough the iron's abundant pores
So subtly into the tiny parts thereof,
Shoves it and pushes, as wind the ship and sails.
The same doth happen in all directions forth:
From whatso side a space is made a void,
Whether from crosswise or above, forthwith
The neighbour particles are borne along
