Of Aire

THE reason, why Aire doth so equall spred,
Is Atomes long, at each end ballanced.
For being long, and each end both alike,
Are like to Weights, which keep it steddy, right:
For howsoere it moves, to what Forme joyne,
Yet still that Figure lies in every line.
For Atomes long, their Formes are like a Thread,
Which interveaves like to a Spiders Web:
And thus being thin, it so subtle growes,
That into every empty place it goes.
