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!

At different seasons of the year, different colors are appropriate in
dress. Light green is the color of freshness, youth, and spring, and
more suitable to be worn in the spring of the year and by young persons,
than later in the season or by mature women. Dark green, like crimson
and orange, is a warmer, more intensified color, with less of liveliness
and freshness.

PURPLE.

Is the type of monarchical enlightenment. With Caucasian nations it has
been the symbolic color of royalty, unt
