The Solar Microscope

You want a powerful lens to see
What animalcules those may be,
Which float about the smallest drop
Of water, and which never stop,
Pursuing each that goes before,
And rolling in unrest for more.
Poets! a watery world is ours,
Where each floats after, each devours,
Its little unsubstantial prey . .
Strange animalcules . . we and they!
