for the anthropologists, it doesn’t. It only gives in some cases the greenish variable tinge I have mentioned, but nothing approaching to the decided greens of Broca’s tables. Given an eye with the right degree of translucency in the membrane and a very thin deposit of yellow pigment spread equally over the surface; the result would be a perfectly green iris. Nature, however, does not proceed quite in this way. The yellow pigment varies greatly in hue; it is muddy yellow, brown, or earthy color, and it never spreads itself uniformly over the surface, but occurs in patches grouped about the pupil and spreads in dull rays or lines and spots, so that the eye which science says “ought to be called green” is usually a very dull blue-grey or brownish-blue, or clay color, and in some rare instances shows a changeable greenish hue. In the remarks accompanying the report of the Anthropomentric Committee of the British Association for 1881 and 1883, it is said that green eyes are more common than the tables indicate, and that eyes that should properly be called green, owing to the popular prejudice against that term, have been recorded as grey or some other color. Does any such prejudice exist? or is it necessary to go about with the open manual in our hands to know a green eye when we see one? No doubt the “popular prejudice” is supposed to have its origin in Shakespeare’s description of jealousy as a green-eyed monster; but if Shakespeare has any great weight with the popular mind the prejudice ought to be the other way, since he is one of those who sing the splendors of the green eye. Thus, in Romeo and Juliet:— The eagle, madam, Hath not so green, so quick, so fair an eye As Paris hath. The lines are, however, nonsense, as green-eyed eagles have no existence; and perhaps the question of the popular prejudice is not worth arguing about. If we could leave out the mixed or neutral eyes, which are in a transitional state—blue eyes with some dark pigment obscuring their blueness, and making them quite unclassifiable, as no two pairs of eyes are found alike—then all eyes might be divided into two great natural orders, those with and those without pigment on the outer surface of the membrane. They could not be called light and dark eyes, since many hazel eyes are really lighter than purple and dark grey eyes. They might, however, be simply called brown and blue eyes, for in all eyes with the outer pigment there is brown, or something scarcely distinguishable from brown; and all eyes without pigment, even the purest greys, have some blueness.
