Those who are short-sighted labour under a particular disadvantage in this respect, being in a manner deprived of the intelligent expression of the eye; and which frequently gives an air of stupidity to the finest face. It is strong and violent passions alone that we ever see marked on such countenances, and which often produce very unfavourable prepossessions. However intelligent we may afterwards find such persons, it is with difficulty we renounce our former prejudices. We are so habituated to judge by external appearances that we too often decide on men's talents by their physiognomy; and having perhaps at first, caught up our judgments prematurely, they mechanically influence us all our lives after; nay the colour, or cut of the clothes will sometimes influence conclusions as to their abilities; and that not always without reason: therefore since strangers may decide upon understanding by so trifling an article as dress, we ought not to be totally inattentive to it, trifling as it may appear. The vivacity, or the languid motion of the eyes, gives the strongest marks to the countenance; and their colour contributes still more to enforce the expression. The different colours of the eyes are dark-hazle, light-hazle, green, blue, grey, and whitish grey. These different colours arise from the different colours of the little muscles, that serve to contract the pupil, and they very often change colour with disorder, and with age. Those most frequent are, the hazle and the blue, and very often both these colours are found in the same eye. Those eyes which are called black are only dark-hazle, which may be easily seen upon close inspection, and only appear black from the contrast with the white of the eye; in all those which have a blue shade that colour becomes the most predominant. Those eyes are reckoned the most beautiful where the shade is the deepest; and either in the black or the blue, the fire, which gives to the eye its finest expression, is most distinguishable. For this reason, the black eyes, as they are called, have the greatest force and vivacity; but the blue are the most delicate, and have the most powerful effect in beauty, as they reflect a greater variety of rays from the tints of which they are composed. This variety in the colour of the eyes, is peculiar to man, and one or two of the brute-creation; in other animals, the colour in any one individual is the same in all the rest. The eyes of the ox are brown; those of sheep of a watery colour; those of goats are grey, &c. and it may also be remarked, that the eyes of most white animals are red; as the rabbit, ferret, &c. "According to Aristotle, in the human species grey eyes are the strongest; blues eyes are weak; full eyes are near sighted, and brown ones require a good light."
