Webster's 1913 Dictionary
  1. \Brain\, n. [OE. brain, brein, AS. bragen, br[ae]gen; akin
    to LG. br["a]gen, bregen, D. brein, and perh. to Gr. ?, the
    upper part of head, if ? =?. [root]95.]
    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.
    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.
    2. (Zo["o]l.) The anterior or cephalic ganglion in insects
       and other invertebrates.
    3. The organ or seat of intellect; hence, the understanding.

    {Brain box} or {case}, the bony on cartilaginous case
       inclosing the brain.
    {Brain coral}, {Brain stone coral} (Zo["o]l), a massive
       reef-building coral having the surface covered by ridges
       separated by furrows so as to resemble somewhat the
       surface of the brain, esp. such corals of the genera
       {M[ae]andrina} and {Diploria}.
    {Brain fag} (Med.), brain weariness. See {Cerebropathy}.
    {Brain fever} (Med.), fever in which the brain is specially
       affected; any acute cerebral affection attended by fever.
    {Brain sand}, calcareous matter found in the pineal gland.
  2. \Brain\, v. t. [imp. & p. p. {Brained}; p. pr. & vb. n.
    1. To dash out the brains of; to kill by beating out the
       brains. Hence, Fig.: To destroy; to put an end to; to
