of Andalusite was called Chiastolite, and was valued as a sacred charm.
Its principal occurrences are in Andalusia, Spain (from which it takes its name), Saxony, Brazil, and in the United States, in Maine, Massachusetts and Connecticut.
Andesine: Soda-Lime Feldspar. It occurs usually massive, is white, gray, greenish or flesh-red in color, and is used commercially in making porcelains.
Andradite: Calcium-Iron Garnet. Common or black garnet, by some called Melanite. It is black, brown, green, brownish-yellow or topaz-yellow. The purest varie­ties are topaz-yellow or light green and transparent. When topaz-yellow they are called Topazolite. It occurs in limestone at Frank­lin, N. J.; in quartz veins in New Hampshire; also in California and Arizona.
Anglesite: Sulphate of Lead. Sulphur Trioxide 26.4%, Lead Oxide 73.6%. It occurs principally as crystals asso­ciated with Galena and other lead ores and is white,
gray or colorless, and transparent. It is mined as an ore of lead in
England, Prussia, Australia, Mexico, and in the Rocky Mountain
States.
Anhydrite: Calcium Sulphate. This mineral belongs to the Barite groups of sulphates and occurs generally in fibrous granular or massive forms, but not often in crystals. It is white in color with often a distinct tinge of blue, red or gray. Fine granular forms are used for ornamental purposes, and as a medium for the use of sculptors. The massive variety is occasionally employed as a land plaster to enrich cultivated soils.
It is found at Stassfurt, Germany; in the Tyrol; in Switzerland and Nova Scotia; also in the United States, in New York and Ten­nessee.
Ankerite: This mineral is a ferruginous Dolomite. Occurs usually in rhombohedral crystals, of white, red or gray color, though it also occurs in fine and coarse granular masses.
It is found at Antwerp, and other places in Northern New York, and
is used in the manufacture of cements.
Annabergite: Hydrous Nickel Arsenate, sometimes called
"Nickel Bloom." Arsenic Pentoxide 38.5%, Nickel
Protoxide 37.4%. It occurs on Smaltite and is
supposed to be a decomposition of this mineral, is apple-green in
