All the ingenious men, and all the scientific men, and all the
fanciful men, in the world, with all the old German bogypainters into
the bargain, could never invent ... anything so curious, and so
ridiculous, as a lobster.

CHARLES KINGSLEY, _The Water-Babies_.

For, Spider, thou art like the poet poor,
Whom thou hast help’d in song.
Both busily, our needful food to win,
We work, as Nature taught, with ceaseless pains,
Thy bowels thou dost spin,
I spin my brains.
SOUTHEY, _To a Spider_.

Last o’er the field the Mite enormous swims,
Swells his red heart, and writhes his giant limbs.
ERASMUS DARWIN, _The Temple of Nature_.
