A piece of glass, or other transparent substance, ground with
two opposite regular surfaces, either both curved, or one
curved and the other plane, and commonly used, either singly

otherwise modifying vision. In practice, the curved surfaces
are usually spherical, though rarely cylindrical, or of some
other figure. Lenses

in section in the figures herewith given: viz., a
plano-concave; b double-concave; c plano-convex; d

(Min.)
A minute mineral form like those common in glassy volcanic
rocks and some slags, not having a definite crystalline
outline and not referable to any mineral species, but marking
the first step in the crystallization process. According to
their form crystallites are called trichites, belonites,
globulites, etc. CrystallizationCrystallization Crys`tal*li*za"tion
(kr[i^]s`tal*l[i^]*z[=a]"sh[u^]n), n. [Cf. F.
cristallization.]
1. (Chem. & Min.) The act or process by which a substance in
solidifying assumes the form and structure of a crystal,
or becomes crystallized.
2. The body formed by crystallizing; as, silver on
precipitation forms arborescent crystallizations.
Note: The systems of crystallization are the several classes
to which the forms are mathematically referable. They
are most simply described according to the relative
lengths and inclinations of certain assumed lines
called axes; but the real distinction is the degree of
symmetry characterizing them. 1. The Isometric, or
Monometric, system has the axes all equal, as in the
cube, octahedron, etc. 2. The Tetragonal, or Dimetric,
system has a varying vertical axis, while the lateral
are equal, as in the right square prism. 3. The
Orthorhombic, or Trimetric, system has the three axes
unequal, as in the rectangular and rhombic prism. In
this system, the lateral axes are called, respectively,
macrodiagonal and brachydiagonal. -- The preceding are
erect forms, the axes intersecting at right angles. The
following are oblique. 4. The Monoclinic system,
having one of the intersections oblique, as in the
oblique rhombic prism. In this system, the lateral axes
are called respectively, clinodiagonal and
orthodiagonal. 5. The Triclinic system, having all
the three intersections oblique, as in the oblique
rhomboidal prism. There is also: 6. The Hexagonal
system (one division of which is called Rhombohedral),
in which there are three equal lateral axes, and a
vertical axis of variable length, as in the hexagonal
prism and the rhombohedron.
Note: The Diclinic system, sometimes recognized, with two
oblique intersections, is only a variety of the
Triclinic. CrystallizeCrystallize Crys"tal*lize (kr[i^]s"tal*l[imac]z), v. t. [imp.
