The late speech and testimony of William Gogor, one of three desperate and incorrigible traytors, execute at the Grass Mercat in Edinburgh, the eleventh day of March, 1681. For disowning his sacred Majesties authority; and owning and adhering to these bloody and murdering principles, contained in that execrable declaration at Sanquhar, Cargils traiterous covenant, and sacrilegious excommunicating of the King, by that arch-traitor Cargil, and avowing of themselves to be bound in conscience, and by their covenant, to murder the King, and all that serve under him; being armed (the time they were apprehended) for that purpose.
