The term crystal is now applied to all symmetrical solid shapes a umed spontaneously by lifele matter. Huxley, Physiography, p. 59. 2. Gla . (a) Gla of a high degree of transparency and freedom from color. It is heavier than ordinary gla , because containing much oxid of lead. ( 6 ) Fine gla used for table-ve els or other table-service, or for ornamental pieces. The term is sometimes used as synonymous with cut gla . (c) The gla cover of a watch-case. 3. A substance resembling rock-crystal or gla in its properties, especially in transparency and clearne . Every man in this age has not a soul of crystal , for all men to read their actions through. Beau , and Fl . , Phil aster, i. 1. 4. In her., the color white: said of that color when described in blazoning a nobleman's escutcheon, according to the system of blazoning by precious stones; pearl, however, is more commonly used.-5. A very fine wide white durant, once used for making nuns' veils. Axis of a crystal. See axis1 and crystallography. Charcot's crystals, in pathol., colorle octahedral or rhomboidal crystals found in the sputum of asthmatic and bronchitic patients. Crystals of Venus, crystallized neutral acetate of copper. [ Venus is here used as a symbol of copper (with allusion to Cyprus).] - Distorted crystal, a crystal whose form varies more or le from the ideal geometrical solid which its symmetry requires. This is due to the extension of certain faces at the expense of others during the growth of the crystal, but in general without altering the interfacial angles. In fact, all crystals are more or le distorted. - Embedded crystals, crystals enveloped within the ma of a rock or other mineral. - Geniculated crystal, a twin or compound crystal, consisting of two or more parts bent at an angle to one another, as is common with the mineral rutile.Iceland crystal, a variety of calcite or crystallized calcium carbonate brought from Iceland, remarkable for its transparency.- Implanted crystals, crystals which pro Snow being apparently frozen cloud or vapour, aggregated by a confused action of crystalline laws. Whewell. 3. Formed by crystallization; of the nature of a crystal, especially as regards its internal structure, cleavage, etc.: opposed to am or pho us . The most definite of the properties of perfect chemical compounds is their crystalline structure. Whewell, Hist. Scientific Ideas, II. 28. It [ice] is composed of crystalline particles, which, though in contact with one another, are, however, not packed together so as to occupy the least po ible space. J. Croll , Climate and Cosmology, p. 252. 4. Resembling crystal; pure; clear; transparent; pellucid: specifically applied in anatomy to several structures, as the crystalline humor, cones, etc. See below. He on the wings of cherub rode sublime, On the crystalline sky. Milton , P. L., vi. 772. 5. In entom., reflecting light like gla : specifically applied to the ocelli or simple eyes when they are apparently colorle , resembling gla . Crystalline cones. See crystalline rods.Crystalline heavens, in the Ptolemaic system of astronomy, two spheres imagined between the primum mobile, or outer circle of the heavens, which by its motion was supposed to carry around all within it, and the firmament. Crystalline humor or lens, a lentiform pellucid body, composed of a transparent firm substance, inclosed in a membranous capsule, and situated in front of the vitreous body and behind the iris of the eye. It is doubly convex, but the posterior surface is more convex than the anterior. The central part is more dense and firm than the exterior parts, and is made up of concentric lamellsæ. It is of high refracting power, and serves to produce that refraction of the rays of light which is nece ary to cause them to meet in the retina and form a perfect image there. See cut under eye. Crystalline rods, crystalline cones, cells specially modified as refractive bodies, forming the end-organs of the nervous apparatus of vision of the Arthropod a. Each group separates off a transparent highly refractive substance, which forms the so-called crystalline cone. Gegenbaur, Comp. Anat. (trans.), p. 264. crystallize Crystalline style, a flexible, transparent body of gristly appearance and unknown function, contained in the pharyngeal cæcum of bivalve mollusks, as species of Mactra. Crystalline ware, a name given by Josiah Wedgwood to fine pottery of his manufacture veined in imitation of natural semi-precious stones, the veining generally going through the paste. Compare granite - ware, agate - ware. II. n. A crystallized rock, or one only partially crystallized, as granite. crystallinity (kris-ta-lin'i-ti), n. [ The tendency to crystallinity observable in large ma es of cast metal. Encyc . Brit ., XIII. 355. crystal lis ability, crystallisable, etc. See crystal liz ability , etc. crystallite (kris'ta-lit), n. [ -ite2 .] 1. Whinstone cooled slowly after fusion.-2. The term suggested by Vogelsang as a general name for aggregations of globulites in various forms. See cumulite, mar garite , and longulite. These terms are used exclusively in describing various groupings of minute drop-like bodies (globulites), seen under the microscope in thin sections of rocks. See globulite .
