A review of Her Royal Highness the Princess Sophia's letter to the Lord Archbishop of Canterbury, and that of Sir Rowland Gwynne to the Right Honourable the Earl of Stamford : Or, A jacobite plot against the Protestant succession discover'd: Occasion'd by a scurrilous and factious libel, lately printed against the most serene House of Hannover. With invincible reasons for an humble adress to Her Most Sacred Majesty to invite over the presumptive heir of the crown, by that means infallibly to secure the Protestant succession, and in that our laws, religion and constitution against the power and intrigues of the French King, in conjunction with the jacobites, and others of this nation.
