Republication \Re*pub`li*ca"tion\ (r?-p?b`l?-k?"sh?n), n.
   A second publication, or a new publication of something
   before published, as of a former will, of a volume already
   published, or the like; specifically, the publication in one
   country of a work first issued in another; a reprint.
   [1913 Webster]

         If there be many testaments, the last overthrows all
         the former; but the republication of a former will
         revokes one of a later date, and establishes the first.
