The face is all but a blank without the eye; the eye seems to concentrate every feature in itself.

It is the eye that smiles, not the lips; it is the eye that listens, not the ear; it is the eye that frowns, not the brow; it is the eye that mourns, not the voice.

The eye sees what it brings the power to see.

How true is this! The sailor on the look-out can see a ship where the landsman can see nothing.

The Esquimaux can distinguish a white fox among the white snow.
