    4. Relevant Information:
       -- A simple database containing 17 Boolean-valued attributes.  The "type"
          attribute appears to be the class attribute.  Here is a breakdown of
          which animals are in which type: (I find it unusual that there are
          2 instances of "frog" and one of "girl"!)
