Of Fire and Flame


Although we at a distance stand, if great
A fire be, the body through1 will heat.
Yet those sharp atomes we do not perceive,
How they fly out, nor how to us they cleave.2
Nor do they3 flame, nor shine they clear and bright       5
When they fly out and on our bodies strike.4
The reason is they loose and scattered fly,
And not in troops, nor do they on heaps lie.
Like small dust rais’d, which,5 scatter’d all about,
We see it not, nor doth it light keep6 out.                         10
But gathered up thick7 to a mountain high,
We then see they in solid earth do8 lie.
Just so do atoms sharp look, clear and bright,
When in heaps lie,9 or in a streaming flight.

Of Fire in the Flint

The reason fire lies1 in flint unseen
Is other figured atoms lie2 between.
For being bound and overpowered by
A multitude, they do in prison lie.
Unless motion do come and let3 them out                           5
With a strong power, which make them4 fly about.
But if that flint be beat to powder small,
To separate the grossest,5 released are all.
And6 when they once are out, they ne’er come back,7
But seek about another form to make.8                               10

What Atoms Make Fire Burn, and What Flame


What makes a spark of fire to burn more quick
Than a great flame? Because ’tis small to stick.
For fire itself is in its nature dry,2
Falls into parts as crowds of atoms lie.
The sharpest atoms keep the body hot;                                 5
To give out heat some atoms forth are shot.
Sometimes the sparks for anger fly about,3
Or, wanting room, do thrust the weakest4out.
They are so sharp, that what they meet, devour56
If other atoms them not overpower:7                                    10
As ants, though8 small, will eat up a dead horse,
So atoms sharp use9 bodies of less force.
Thus atoms sharp grow10 sharper by degrees,
As stings in flies are not so sharp as bees’.
And when they meet a body solid, flat,                                 15
The weakest fly; the sharpest work on that.
Those that are not so sharp do fly about
To seek some lighter matter to eat11 out.
Thus12 lighter atoms do turn air13 to flame,
Because more thin and porous is the same.                         20
Thus flame is not so hot as burning coal:14
The atoms are too weak to take fast hold.15
The sharpest into firmest bodies fly,
But if their strength be small, they quickly die.
Or if their number be not great, but small,                          25
The blunter atoms beat and quench out all.

Of the Sound of Water, Air and Flame


When crowds of atoms meet, not joinèd close,
By Motion quick they2 give each other blows.3
So atoms hollow, which are long and round,
When they do strike, do make the greatest sound.
Not that there’s anything that moves therein                      5
To make rebounds, but that their form’s more thin.4
For being thin, they larger are, and wide,
Which make them apt to strike each other’s side.
In larger bulks, encounters are more fierce
When they do5 strike, though not so quick to pierce.       10
This is the reason water, air, and flame
Do make most noise when motions move the same.
For atoms loose are like to people rude,
And make great6 noise when in a multitude.

Flame Compared to the Tide of the Sea



Like as the tide, so flame doth2 ebb and flow,
For it will sink3 and then straight higher grow.
And if suppressed, it in a rage breaks4 out,
Spreading5 itself in several parts about.
Some think the salt doth make6 the sea to move,7              5
If so, then salt in flame the like may prove.
And if it be that8 salt all motions makes,
Then life, the chief, from salt its motion9 takes.
