Choledology \Chol`e*dol"o*gy\, n. [Gr. cholh` bile + -logy. Cf.
   F. chol['e]dologie.] (Med.)
   A treatise on the bile and bilary organs. --Dunglison.
   [1913 Webster]

   Note: Littr['e] says that the word chol['e]dologie is
         absolutely barbarous, there being no Greek word ?. A
         proper form would be cholology.
         [1913 Webster]
