<hw>Cal"cite</hw> <tt>(?)</tt>, <tt>n.</tt> <ety>[L. <ets>calx</ets>, <ets>calcis</ets>, lime.]</ety> <fld>(Min.)</fld> <def>Calcium carbonate, or carbonate of lime. It is rhombohedral in its crystallization, and thus distinguished from aragonite. It includes common limestone, chalk, and marble. Called also <altname>calc-spar</altname> and <altname>calcareous spar</altname>.</def>

<note>&hand; <i>Argentine</i> is a pearly lamellar variety; <i>aphrite</i> is foliated or chalklike; <i>dogtooth spar</i>, a form in acute rhombohedral or scalenohedral crystals; <i>calc-sinter</i> and <i>calc-tufa</i> are lose or porous varieties formed in caverns or wet grounds from calcareous deposits; <i>agaric mineral</i> is a soft, white friable variety of similar origin; <i>stalaclite</i> and <i>stalagmite</i> are varieties formed from the drillings in caverns. <i>Iceland spar</i> is a transparent variety, exhibiting the strong double refraction of the species, and hence is called <i>doubly refracting spar</i>.</note>

It is a member of the alkaline earth group of elements. Atomic weight 40. Symbol Ca.</def>

<note>&hand; <i>Calcium</i> is widely and abundantly disseminated, as in its compounds <i>calcium carbonate</i> or limestone, <i>calcium sulphate</i> or gypsum, <i>calcium fluoride</i> or fluor spar, <i>calcium phosphate</i> or apatite.</note>

<cs><col>Calcium light</col>, <cd>an intense light produced by the incandescence of a stick or ball of lime in the flame of a combination of oxygen and hydrogen gases, or of oxygen and coal gas; -- called also <altname>Drummond light</altname>.</cd></cs>
