Brown eyes express animal passions rather than intellect, and the higher moral feelings. They are frequently equalled in their own peculiar kind of eloquence by the brown or dark eyes in civilised dogs. In animals there is, in fact, often an exaggerated eloquence of expression. To judge from their eyes, caged cats and eagles in the Zoological Gardens are all furred and feathered Bonnivards. Even in the most intellectual of men the brown eye speaks more of the heart than of the head. In the inferior creatures the black eye is always keen and cunning or else soft and mild, as in fawns, doves, aquatic birds, etc.; and it is remarkable that in man also the black eye—dark brown iris with large pupil—generally has one or the other of these predominant expressions. Of course, in highly-civilised communities, individual exceptions are extremely numerous. Spanish and negro women have wonderfully soft and loving eyes, while the cunning weasel-like eye is common everywhere, especially amongst Asiatics. In high-caste Orientals the keen, cunning look has been refined and exalted to an expression of marvellous subtlety—the finest expression of which the black eye is capable. The blue eye—all blues and greys being here included—is, _par excellence_, the eye of intellectual man; that outer warm-colored pigment hanging like a cloud, as it were, over the brain absorbs its most spiritual emanations, so that only when it is quite blown away are we able to look into the soul, forgetting man’s kinship with the brutes. When one is unaccustomed to it from always living with dark-eyed races, the blue eye seems like an anomaly in nature, if not a positive blunder; for its power of expressing the lower and commonest instincts and passions of our race is comparatively limited; and in cases where the higher faculties are undeveloped it seems vacant and meaningless. Add to this that the ethereal blue color is associated in the mind with atmospheric phenomena rather than with solid matter, inorganic or animal. It is the hue of the void, expressionless sky; of shadows on far-off hill and cloud; of water under certain conditions of the atmosphere, and of the unsubstantial summer haze, Whose margin fades Forever and forever as I move.
