   inorganique.]

   an organized structure; unorganized; lifeness; inanimate; as,

         series of substances (as minerals, metals, etc.), which
         are not directly connected with vital processes, either
         in origin or nature, and which are broadly and
         relatively contrasted with organic subscances. See
