Spectrum \Spec"trum\, n.; pl. {Spectra}. [L. See {Specter}.]
      1. An apparition; a specter. [Obs.]
  
      2. (Opt.)
            (a) The several colored and other rays of which light is
                  composed, separated by the refraction of a prism or
                  other means, and observed or studied either as spread
                  out on a screen, by direct vision, by photography, or
                  otherwise. See Illust. of {Light}, and {Spectroscope}.
            (b) A luminous appearance, or an image seen after the eye
                  has been exposed to an intense light or a strongly
                  illuminated object. When the object is colored, the
                  image appears of the complementary color, as a green
                  image seen after viewing a red wafer lying on white
                  paper. Called also {ocular spectrum}.
  
      {Absorption spectrum}, the spectrum of light which has passed
            through a medium capable of absorbing a portion of the
            rays. It is characterized by dark spaces, bands, or lines.
           
  
      {Chemical spectrum}, a spectrum of rays considered solely
            with reference to their chemical effects, as in
            photography. These, in the usual photogrophic methods,
            have their maximum influence at and beyond the violet
            rays, but are not limited to this region.
  
      {Chromatic spectrum}, the visible colored rays of the solar
            spectrum, exhibiting the seven principal colors in their
            order, and covering the central and larger portion of the
            space of the whole spectrum.
  
      {Continous spectrum}, a spectrum not broken by bands or
            lines, but having the colors shaded into each other
            continously, as that from an incandescent solid or liquid,
            or a gas under high pressure.
  
      {Diffraction spectrum}, a spectrum produced by diffraction,
            as by a grating.
  
      {Gaseous spectrum}, the spectrum of an incandesoent gas or
            vapor, under moderate, or especially under very low,
            pressure. It is characterized by bright bands or lines.
  
      {Normal spectrum}, a representation of a spectrum arranged
            upon conventional plan adopted as standard, especially a
            spectrum in which the colors are spaced proportionally to
            their wave lengths, as when formed by a diffraction
            grating.
  
      {Ocular spectrum}. See {Spectrum}, 2
            (b), above.
  
      {Prismatic spectrum}, a spectrum produced by means of a
            prism.
  
      {Solar spectrum}, the spectrum of solar light, especially as
            thrown upon a screen in a darkened room. It is
            characterized by numerous dark lines called Fraunhofer
            lines.
  
      {Spectrum analysis}, chemical analysis effected by comparison
            of the different relative positions and qualities of the
            fixed lines of spectra produced by flames in which
            different substances are burned or evaporated, each
            substance having its own characteristic system of lines.
           
  
      {Thermal spectrum}, a spectrum of rays considered solely with
            reference to their heating effect, especially of those
            rays which produce no luminous phenomena.

Gasoscope \Gas"o*scope\, n. [Gas + -scope.]       An apparatus for detecting the presence of any dangerous gas,       from a gas leak in a coal mine or a dwelling house.

Goose \Goose\ (g[oomac]s), n.; pl. {Geese} (g[emac]s). [OE. gos,       AS. g[omac]s, pl. g[emac]s; akin to D. & G. gans, Icel.       g[be]s, Dan. gaas, Sw. g[aring]s, Russ. guse. OIr. geiss, L.       anser, for hanser, Gr. chh`n, Skr. ha[msdot]sa. [root]233.       Cf. {Gander}, {Gannet}, {Ganza}, {Gosling}.] (Zo[94]l.)       1. Any large web-footen bird of the subfamily {Anserin[91]},             and belonging to {Anser}, {Branta}, {Chen}, and several             allied genera. See {Anseres}.          Note: The common domestic goose is believed to have been                derived from the European graylag goose ({Anser                anser}). The bean goose ({A. segetum}), the American                wild or Canada goose ({Branta Canadensis}), and the                bernicle goose ({Branta leucopsis}) are well known                species. The American white or snow geese and the blue                goose belong to the genus {Chen}. See {Bernicle},                {Emperor goose}, under {Emperor}, {Snow goose}, {Wild                goose}, {Brant}.          2. Any large bird of other related families, resembling the             common goose.          Note: The Egyptian or fox goose ({Alopochen [92]gyptiaca})                and the African spur-winged geese ({Plectropterus})                belong to the family {Plectropterid[91]}. The                Australian semipalmated goose ({Anseranas semipalmata})                and Cape Barren goose ({Cereopsis                Nov[91]-Hollandi[91]}) are very different from northern                geese, and each is made the type of a distinct family.                Both are domesticated in Australia.          3. A tailor's smoothing iron, so called from its handle,             which resembles the neck of a goose.          4. A silly creature; a simpleton.          5. A game played with counters on a board divided into             compartments, in some of which a goose was depicted.                         The pictures placed for ornament and use, The twelve                      good rules, the royal game of goose.   --Goldsmith.          {A wild goose chase}, an attempt to accomplish something             impossible or unlikely of attainment.          {Fen goose}. See under {Fen}.          {Goose barnacle} (Zo[94]l.), any pedunculated barnacle of the             genus {Anatifa} or {Lepas}; -- called also {duck             barnacle}.
