Although among Caucasian nations, and especially in cosmopolitan America, we do not adduce intellectual superiority from the shades or degrees of whiteness, yet it is said of the Moors that the more the color approaches the _black_, the handsomer and of more decisive character are the men. It is a physiological fact brought to light partially through the census, that black-eyed races and black-eyed people are more subject to blindness than others. It has also been shown that black-eyed men are not as good marksmen as blue-eyed or light-eyed men. Not only are different races of men subject to different diseases, but statistics prove that among Caucasian nations, complexion and disease are in some way connected, as for instance, consumption is more rife among dark-haired and dark-eyed people than others, and more rapid with those dark-haired and dark-eyed people who have very fair complexion. As the difference between golden and black hair lies in that there is in the one case an excess of sulphur and oxygen with a deficiency of carbon, and in the other an excess of carbon and a deficiency of sulphur and oxygen, it can easily be seen why such deficiency or excess, if arising from idiosyncrasy of the system, should predispose to dissimilar diseases. But here a wide field yet lies open for experimental and physiological research. GREEN. There is scarcely a color but has been or is held sacred by some nation or religion. With Mahommedans green is the sacred hue. The prophet originally wore a turban of that dye, and the sultan shows due preference for that color. The tomb of David, which is in possession of the Mahommedans, and which was at great hazard visited by a lady within the past few years, is covered by a green satin tapestry, and over it hangs a satin canopy of red, blue, yellow, and green stripes, the three primitive and the sacred, compound color. Green also seems to have been the sacred color in ancient Peru, virgins of the sun wearing robes of that hue. The ancient Mexican priests also, in the performance of their functions, wore crowns of green and yellow feathers, and at their ears hung green jewels. Precious stones of a green color were held in higher estimation by the Aztecs than any other. When the Spaniards were first admitted to an audience with Montezuma, he wore no other ornament on his head than a _panache_ of plumes of royal green. Green comes in the class of secondary colors, being a compound of yellow and blue, and signifies pale, new, fresh, growing, flourishing (like a green bay tree); and also unripe, when applied to either fruits or men, which, as far as the human is concerned, is a term of reproach. A person without experience, either in position, behavior, or use of anything, is termed green, and laughed at. They are fresh, new, and, instead of the admiring exclamation, How green it is! as applied to a plant, is the reproachful one, How green he is!
