   A message sent by telegraph; a telegraphic dispatch.

   Note: ``A friend desires us to give notice that he will ask
         leave, at some convenient time, to introduce a new word
         into the vocabulary. It is telegram, instead of
         telegraphic dispatch, or telegraphic communication.''
