8,000 martyrs

In response to my mention in the previous post of 8,000 Dissenters dying in prisons during the reign of Charles II and James II, a dear friend, Ron Miller, made this extremely helpful comment: "The 8000 number is found in De Foe's preface to De Laune's A Plea for the Non-Conformists, p 4 in the 1720 edition I have, the seventh paragraph from the start. De Foe says this, 'I am sorry to say, he is one of near eight thousand Protestant Dissenters that perish'd in prison in the days of that merciful [sarcasm?!] prince, King Charles the Second'."
