are shown in the nativity or map of the heavens at a person’s birth. An effective talisman for the protection of horses and their riders was a winged horse cut on an amethyst. The ancients connected the amethyst with the ninth celestial mansion—the mansion of Sagittarius—and there is no reason for allotting it to any other. ANATASE. The name is derived from the Latin ANATASES, elevation. It was so named from the length of its chief axis. This mineral is composed of Titanic acid which crystallizes in fine, transparent stones of brown, dark blue or black, of adamantine lustre. The anatase, which equals the opal in hardness, cannot be traced in ancient writings. It is rarely used in jewellery. In harmony with the philosophy of gem influence it is connected with the sign Sagittarius. ANDALUSITE. This stone, first discovered in Andalusia, derives its name from that rich mineral province of Spain—the Tarshish of the Bible, the Tartessus of ancient geography, the Bætica of the Romans. Its colours are light bottle-green, pearl grey, flesh and pink. It is extremely dichroic, showing the twin colours red and leaf-green—the red gleaming from the stone in antithesis to its common hue. The Andalusite is as hard as the garnet or zircon. Professor Dana moistened specimens with nitrate of cobalt, after which they assumed a blue colour. This mineral may have been known to the ancients, but identification is difficult. Ancient philosophy would connect it with the zodiacal Aquarius. APATITE. Apatite is a mineral which obtained its name from the Greek word APATAO, to deceive, because it deceived old students who confounded it with aquamarine, chrysolite, tourmaline, etc. Abraham Werner (the author of the Neptunian theory that all mineral substances were once contained in watery solution), first demonstrated in the 18th century the true nature of apatite which is a phosphate of lime with fluorite and chloride of calcium. The lustre varies from transparent to opaque, and is vitreous to sub-resinous. It is much softer than tourmaline, its degree of hardness being but 5; for this reason it is but little used in the manufacture of jewellery. Its colours are pale sea-green, blue-green (in which colouring it is sometimes called Moroxite), yellowish-green (in which colouring it is often called Asparagus stone), yellow, violet, white, grey, brown, red, colourless, and transparent. Professor Judd, F.R.S., found a concretion specimen of apatite when cutting a mass of teak wood—a particularly rare find. In agreement with the ancient system the apatite is astrologically under the zodiacal Pisces.
