(5) in borax. Dissolves with effervescence. In large quantities gives a semi-crystalline bead. (6) in mic. salt. As in borax, but the saturated bead is milk-white. (7) with carb. soda. Fuses, and is partially absorbed leaving the lime on the surface. (8) Special reactions. As witherite. * * * * * LIME. * * * * * Mineral. Gypsum Formula. [.Ca][...S] + 2[.H]. Behavior (1) in glass-bulb. Turns white, giving off water and being converted into plaster of Paris. (2) in open tube. -- (3) on charcoal. In the reducing flame forms CaS, which has an alkaline reaction on test paper, and gives a sulphur-reaction when laid on silver and moistened. (4) in forceps. Fuses with difficulty to a bead, coloring the flame red. (5) in borax. Dissolves to a clear bead, which gives the lime- reaction. (6) in mic. salt. As in borax. (7) with carb. soda. Behaves as lime. The alkaline mass laid on silver and moistened gives the sulphur-reaction. (8) Special reactions. Gives the sulphuric-acid reaction. * * * * * Mineral. Apatite { Cl Formula.

Previously dipped in SO^{3} colors the flame green, afterwards red. (5) in borax. Dissolves easily and when in some quantity gives an opaline bead. (6) in mic. salt. Gives the lime-reaction. (7) with carb. soda. Is infusible. The alkali is absorbed, leaving the lime on the on the surface of the charcoal. (8) Special reactions. With microcosmic salt and oxide of copper, gives the chlorine-reaction. With microcosmic salt in the open tube evolves fluorine. * * * * * Mineral. Pharmacolite Formula. [.Ca]^{2}[.....As] + 6[.H].
