hostile orator
Note from 'Justification' chapter from 'Memoirs Of My Life And Writing' by Gibbon

I can never forget the delight with which that diffusive and ingenious orator, Mr. Burke, was heard by all sides of the house, and even by those whose existence he proscribed. (See Mr. Burke's speech on the Bill of Reform, pp. 72-80.) The Lords of Trade blushed at their insignificancy, and Mr. Eden's appeal to the two thousand five hundred volumes of our Reports served only to excite a general laugh. I take this opportunity of certifying the correctness of Mr. Burke's printed speeches, which I have heard and read.
