Dyslogistic \Dys`lo*gis"tic\, a. [Gr. ? ill, bad, + ? discourse,
   fr. ? to speak.]
   Unfavorable; not commendatory; -- opposed to {eulogistic}.

         There is no course of conduct for which dyslogistic or
         eulogistic epithets may be found.        --J. F.
                                                  Stephen.

         The paternity of dyslogistic -- no bantling, but now
         almost a centenarian -- is adjudged to that genius of
         common sense, Jeremy Bentham.            --Fitzed.
                                                  Hall.
