DUll Atomes flat, when they together joyne,
And with each other in a heape combine;
This Body thicke doth stop all passage so,
Keeps Motion out, so num'd the Body grow.
Atomes that are sharpe, in which Heate dothlive,
Being smothered close, no heate can give:
But if those Atomes flat meet in the Braine,
They choake the Spirits, can no heate obtaine.
