clothed with many plants of many kinds,
with birds singing on the bushes,
insects flitting about and worms crawling
through the damp earth,
and to reflect that these forms, so different
yet so dependent on each other in so complex a manner,
have all been produced by simple laws.There is grandeur in this
view of life, with its several powers, having been originally breathed
by the Creator into a few forms or into one; and that,
whilst this planet has gone circling on according to the fixed law of gravity,
from so simple a beginning endless forms most beautiful
and most wonderful have been, and are being evolved.
