Man cannot fix his eye on the sun, and so far seems imperfect. In Siberia, a late traveller found men who could see the satellites of Jupiter with their unarmed eye. In some respects the animals excel us. The birds have a longer sight, beside the advantage by their wings of a higher observatory. A cow can bid her calf, by secret signal, probably of the eye, to run away, or to lie down and hide itself. The jockeys say of certain horses, that "they look over the whole ground." The outdoor life, and hunting, and labor, give equal vigor to the human eye. A farmer looks out at you as strong as the horse; his eye-beam is like the stroke of a staff. An eye can threaten like a loaded and levelled gun, or can insult like hissing or kicking; or, in its altered mood, by beams of kindness, it can make the heart dance with joy. The eye obeys exactly the action of the mind. When a thought strikes us, the eyes fix, and remain gazing at a distance; in enumerating the names of persons or of countries, as France, Germany, Spain, Turkey, the eyes wink at each new name. There is no nicety of learning sought by the mind, which the eyes do not vie in acquiring. "An artist," said Michael Angelo, "must have his measuring tools not in the hand, but in the eye;" and there is no end to the catalogue of its performances, whether in indolent vision (that of health and beauty) or in strained vision (that of art and labor). Eyes are bold as lions,--roving, running, leaping, here and there, far and near. They speak all languages. They wait for no introduction; they are no Englishmen; ask no leave of age or rank; they respect neither poverty nor riches, neither learning nor power, nor virtue, nor sex, but intrude, and come again, and go through and through you, in a moment of time. What inundation of life and thought is discharged from one soul into another through them! The glance is natural magic. The mysterious communication established across a house between two entire strangers moves all the springs of wonder. The communication by the glance is in the greatest part not subject to the control of the will. It is the bodily symbol of identity of nature. We look into the eyes to know if this other form is another self, and the eyes will not lie, but make a faithful confession what inhabitant is there. The revelations are sometimes terrific. The confession of a low, usurping devil is there made, and the observer shall seem to feel the stirring of owls, and bats, and horned hoofs, where he looked for innocence and simplicity. 'Tis remarkable, too, that the spirit that appears at the windows of the house does at once invest himself in a new form of his own to the mind of the beholder.
