Far as Creation's ample range extends,
The scale of sensual, mental pow'rs ascends:
Mark how it mounts, to Man's imperial race,
From the green myriads in the peopled grass: 210
What modes of sight betwixt each wide extreme,
The mole's dim curtain, and the lynx's beam:
Of smell, the headlong lioness between,
And hound sagacious on the tainted green:
Of hearing, from the life that fills the Flood, 215
To that which warbles thro' the vernal wood:
The spider's touch, how           fine!
