Of the Sound of Water, Air, and Flame.

VVhen Crowds of Atomes meet, not joyned close,
By Motion quick they give each other blows ;
When they do strike, do make the greatest Sound;
Not that there's any thing that moves therein,
To make Rebounds, but that their Form's more thin ;
For being thin, they larger are and wide,
Which makes them apt to strike each others side.
In larger Bulks encounters are more fierce,
When they do strike, though not so quick to peirce:
This is the reason, Water, Air, and Flame,
Do make most noise when Motions move the same;
For Atomes loose are like to People rude,
And make great Noise, when in a Multitude.
 

The encounters of Bodies make all Sound.

Long and Round Atomes are more Thin, than Flat, or Sharp, by reason they are more Hollow, and their Hollowness makes their Bulk bigger, though not their Weight heavier.
