   {Catarrhal pneumonia}, or {Broncho-pneumonia}, is
      inflammation of the lung tissue, associated with catarrh
      and with marked evidences of inflammation of bronchial
      membranes, often chronic; -- also called {lobular
      pneumonia}, from its affecting single lobules at a time.
      

   {Croupous pneumonia}, or ordinary pneumonia, is an acute
      affection characterized by sudden onset with a chill, high
      fever, rapid course, and sudden decline; -- also called
      {lobar pneumonia}, from its affecting a whole lobe of the
      lung at once. See under {Croupous}.

   {Fibroid pneumonia} is an inflammation of the interstitial
      connective tissue lying between the lobules of the lungs,
      and is very slow in its course, producing shrinking and
      atrophy of the lungs.
