The West End squares are pleasant spots for our purpose, and at many doors we shall have to make a call. In Landsdowne House (in Berkeley Square) it is supposed by many that Lord Shelburne, Colonel Barre, and Dunning wrote "Junius"; certain it is that the Marquis of Landsdowne, in 1809, acknowledged the possession of the secret, but died the following week, before he could disclose it. Here, in 1774, that persecuted philosopher, Dr. Priestley, the librarian to Lord Shelburne, discovered oxygen. In this square Horace Walpole (that delightful letter-writer) died and Lord Clive destroyed himself. Then there is Grosvenor Square, where that fat, easy-going Minister, Lord North, lived, where Wilkes the notorious resided, and where the Cato-Street conspirators planned to kill all the Cabinet Ministers, who had been invited to dinner by the Earl of Harrowby. In Hanover Square we visit Lord Rodney, &c. In St. James's Square we recall William III. coming to the Earl of Romney's to see fireworks let off and, later, the Prince Regent, from a balcony, displaying to the people the Eagles captured at Waterloo. Queen Caroline resided here during her trial, and many of Charles II.'s frail beauties also resided in the same spot. In Cavendish Square we stop to describe the splendid projects of that great Duke of Chandos whom Pope ridiculed. Nor are the lesser squares by any means devoid of interest. In Pall Mall the laziest gleaner of London traditions might find a harvest. On the site of Carlton House--the Prince Regent's palace--were, in the reign of Henry VI., monastic buildings, in which (reign of Henry VIII.) Erasmus afterwards resided. They were pulled down at the Reformation. Nell Gwynn lived here, and so did Sir William Temple, Swift's early patron, the pious Boyle, and that poor puff-ball of vanity and pretence--Bubb Doddington. Here we have to record the unhappy duel at the "Star and Garter" tavern between Lord Byron and Mr. Chaworth, and the murder of Mr. Thynne by his rival, Count Koeningsmark. There is Boydell's Shakespeare Gallery to notice, and Dodsley's shop, which Burke, Johnson, and Garrick so often visited. There is also the origin of the Royal Academy, at a house opposite Market Lane, to chronicle, many club-houses to visit, and curious memorabilia of all kinds to be sifted, selected, contrasted, mounted, and placed in sequence for view. Then comes Marylebone, formerly a suburb, famous only for its hunting park (now Regent's Park), its gardens, and its bowling-greens. In Queen Elizabeth's time the Russian ambassadors were sent to hunt in Marylebone Park; Cromwell sold it--deer, timber, and all--for L13,000. The Marylebone Bowling Greens, which preceded the gardens, were at first the resort of noblemen and gentlemen, but eventually highwaymen began to frequent them. The Duke of Buckingham (whom Lady Mary Wortley Montagu glances at in the line, "Some dukes at Marybone bowl time away")
