Of Many Worlds in this World

Just like as in a nest of boxes round,
Degrees of sizes in each box are found:
So, in this world, may many others be,
Thinner and less, and less still by degree:
Although they are not subject to our sense,
A world may be no bigger than two-pence.
Nature is curious, and such works may shape,
Which our dull senses easily escape:
For creatures, small as atoms, may be there,
If every one a creature’s figure bear.
If atoms four, a world can make, then see
What several worlds might in an ear-ring be:
For millions of those atoms may be in
The head of one small, little, single pin.
And if thus small, then ladies may well wear
A world of worlds, as pendants in each ear.
