Of Cold Winds

As water rarified doth make1 winds blow,
So winds when rarified2 do colder grow.
For if they thin are3 rarified, then they
Do further blow, and spread out every way.
So cold they are, and sharp as needle points,4                          5
For by the thinness breaks and disunites,5
Into such6 atoms fall, sharp figures be,7
Which porous bodies pierce, if we could8 see.
Yet some will think, if air were parted so
The winds could not have such strong force to blow.             10
’Tis true, if atoms all were blunt and flat,9
Or round like rings, they could not pierce, but pat.10
But by dividing, they so sharp do grow,11
That12 through all porous bodies they do go.13
But when the winds are soft, they intermix,                             15
As water doth, and in one body fix.
They rather14 wave than blow as fans are spread,
Which ladies use to cool their cheeks when red,
Or like as water drops that disunite15
Feel harder than when mixed they16 on us light,                     20
Unless such streams upon our heads do17 run,
As we a shelter seek, the wet to shun.
But when a drop congealèd is with cold,
As hailstones are, then it more strength18 doth hold.
For19 flakes of snow may have more quantity                          25
Than hailstones, yet not have more20 force thereby.
They fall so soft that they scarce21 strike our touch;
Hailstones we feel and know their weight too much.
But figures that are flat are dull and slow,
Make weak impressions22 wheresoe’er they go.                      30
For let ten times the quantity of steel
Be beaten thin,23 no hurt by that you’ll feel.
But if that one will take a needle small,
Whose point is sharp, and prick24 the flesh withal,
Straight it shall hurt, and put the flesh to pain,                        35
Which greater strength doth not of what is25 plain.
For though26 you press it hard against the skin,
’T may27 heavy feel, but cannot28 enter in.
And so29 the wind that’s thin and30 rarified
May press31 us down, but never32 pierce the side.                   40
Or take a blade that’s flat, though strong and great,
And with great strength upon one’s head it33 beat:
You’ll break the skull, but not knock out his34 brains,
Which arrows sharp soon do, and with less pains.
Thus what is small is subtler and more35 quick,                       45
For all small points36 in porous bodies stick.
Winds broken small to atoms, when they37 blow,
Are colder much than when they38 streaming flow,
For all which knit39 and united close40
Much stronger are, and give41 the harder blows.                     50
This shows what’s closest in itself42 to be,
Although an atom in43 its small degree.
Take quantity, for quantity alike,
Union44 more than mixture hard shall strike.

What Makes Echo

The same motion which from the mouth doth move1
Runs through the air, which we by echo prove.2
As several letters in one word do join,3
So several figures through the air combine.
The air is wax, words seal, and give the print,           5
And so4 an echo in the air do mint.
And while those figures last, they life5 maintain;
When motion wears them out, echo is6 slain.
As sugar in the mouth doth melt with7 taste,
So echo in the air itself doth waste.                             10

The Circle of the Brain Cannot Be Squared.

A circle round divided in four parts
Hath been great1 study amongst2 men of arts;
Since Archimede’s or Euclid’s time, each brain3
Hath on a line been stretched, yet all in vain,4
And every thought hath been a figure set;                           5
Doubts cyphers were, hopes as triangles met;5
There was6 division and subtraction made,
And lines drawn out, and points exactly laid.
But none hath yet by demonstration found7
The way by which to square a circle round.8                      10
Thus9 while the brain is round, no squares10 will be:
While thoughts are in divisions,11 no figures will agree.
