Animalcules - The Cheese Mite - The Hydra, or Polypes.

The smallest creature in existence

Has limbs and sinews, blood, and heart, and brain,

Life and her proper functions to sustain,

Through the whole fabric, smaller than a grain !

What more can our penurious reason grant

To the large whale, or castled elephant; To those enormous terrors of the Nile,

The crested snake, and long-tail'd crocodile ;Than that all differ but in shape and name,

Each destin'd to a less or larger frame? Prior' s Solomon.
