     fr. Gr. kora`llion.]
     1. (Zool.) The hard parts or skeleton of various Anthozoa,
        and of a few Hydrozoa. Similar structures are also formed
        by some Bryozoa.

     Note: The large stony corals forming coral reefs belong to
           various genera of Madreporaria, and to the hydroid
           genus, Millepora. The red coral, used in jewelry, is
           the stony axis of the stem of a gorgonian ({Corallium
           rubrum) found chiefly in the Mediterranean. The fan
           corals, plume corals, and sea feathers are species
           of Gorgoniacea, in which the axis is horny.
           Organ-pipe coral is formed by the genus Tubipora, an
           Alcyonarian, and black coral is in part the axis of
           species of the genus Antipathes. See Anthozoa,
           Madrepora.

From The Collaborative International Dictionary of English v.0.48 :

  Brain \Brain\ (br[=a]n), n. [OE. brain, brein, AS. bragen,
     br[ae]gen; akin to LG. br[aum]gen, bregen, D. brein, and
     perh. to Gr. bre`gma, brechmo`s, the upper part of head, if
     [beta] = [phi]. [root]95.]
     [1913 Webster]
     1. (Anat.) The whitish mass of soft matter (the center of the
        nervous system, and the seat of consciousness and
        volition) which is inclosed in the cartilaginous or bony
        cranium of vertebrate animals. It is simply the anterior
        termination of the spinal cord, and is developed from
        three embryonic vesicles, whose cavities are connected
        with the central canal of the cord; the cavities of the
        vesicles become the central cavities, or ventricles, and
        the walls thicken unequally and become the three segments,
        the fore-, mid-, and hind-brain.
        [1913 Webster]
  
     Note: In the brain of man the cerebral lobes, or largest part
           of the forebrain, are enormously developed so as to
           overhang the cerebellum, the great lobe of the
           hindbrain, and completely cover the lobes of the
           midbrain. The surface of the cerebrum is divided into
           irregular ridges, or convolutions, separated by grooves
           (the so-called fissures and sulci), and the two
           hemispheres are connected at the bottom of the
           longitudinal fissure by a great transverse band of
           nervous matter, the corpus callosum, while the two
           halves of the cerebellum are connected on the under
           side of the brain by the bridge, or pons Varolii.
           [1913 Webster]
  
     2. (Zool.) The anterior or cephalic ganglion in insects and
        other invertebrates.
