"With beat of systole and of diastole
One grand great life throbs through earth's giant heart,
And mighty waves of single Being roll
From nerveless germ to man, for we are part
Of every rock and bird and beast and hill,
One with the things that prey on us, and one with what we kill."
And:—
"From lower cells of waking life we pass
To full perfection; thus the world grows old:"
