. Bulletin - New York State Museum. Science. GUIE>E TO THE MIXEUALOGIC COLLECTIONS 85 Witherite is mined at Fallowfield Eng. Small deposits of the mineral occur near Lexington Ivy. and at Thunder bay, Lake Superior. It is used as an adulterant of white lead and in the refining of beet sugar molasses. Strontianite SrC03 Strontianite, the carbonate of strontium, contains $ carbon dioxid and $ strontia. Distinct orthorhombic crystals are quite rare. Eadiated, spear-shaped or acicular crystalline aggregates are common; also columnar, fibrous and granular masses. The luster of strontianite is vitreous and the color is white, pinkish or greenish. Strontianite is found in New York at or near Schoharie, Scho- harie co., Clinton, Oneida co. and in several localities in Jeffer- son county. It is an important source of strontium compounds used in the manufacture of fireworks. Cerussite (white lead ore) PbCO., Cerussite, the carbonate of lead, contains $ carbon dioxid and $ lead oxid. It sometimes carries a little silver. The crystals of cerussite are orthorhombic, often of tabular.
