The family insanity, shown in the case of George II. by his persistence in wearing his Dettingen old clothes; more notorious and less possible of concealment in that of George III.; well known to all but the people as to George IV., who actually tried to persuade the Duke of Wellington that he (George) had led a regiment at Waterloo, was also marked in William IV. In April, 1832, the King's own secretary admits "distressing symptoms" and "nervous excitement," but says that the attack "is now subsiding." Raikes, a Tory, and also a king-worshipper, in his, "Diary," under date May the 27th, 1834, says, after speaking of the King's "excitement" and "rather extraordinary" conduct, that "at the levee a considerable sensation was created the other day by his insisting that an unfortunate wooden-legged lieutenant should kneel down." On June 11th, visiting the Royal Academy, the President showed the King, amongst others, the portrait of Admiral Napier, and was astonished to hear his Majesty at once cry out: "Captain Napier may be damned, sir, and you may be damned, sir; and if the Queen was not here, sir, I would kick you downstairs, sir." The King's brother, his Royal Highness the Duke of Gloucester, died November 20th, 1834. Raikes says of him: "He was not a man of talent, as may be inferred from his nickname of Silly Billy." This is the Royal Family, the head of which, according to Mr. Disraeli, was "physically and mentally incapable of performing the regal functions," and which yet, according to the brilliant statesman, so fitly represents the intelligence and honor of Great Britain! In 1836, Sir William Knighton died. He had been made private secretary to the late King, and had made his fortune by means of some papers which Colonel Macmahon, confidant of George IV., had when dying, and which came into Knighton's hands as medical attendant of the dying man. Sir W. Knighton was made a "Grand Cross," not for his bravery in war, or intelligence in the State, but for his adroit manipulation of secrets relating to Lady Jersey, Mrs. Fitzherbert, and the Marchioness of Conyngham. Sir William Knighton and the latter lady were supposed to have made free with £300,000; but great larcenies win honor, and Sir W. Knighton died respected. In August, 1836, William--hearing that the Duke of Bedford had helped O'Connell with money--ordered the Duke's bust, then in the Gallery at Windsor, to be taken down, and thrown in the lime-kilns. On June 20th, 1837, William IV. died. Ernest, Duke of Cumberland, by William's death, became King of Hanover, and was on the same day publicly hissed in the Green Park. Naturally, in this loving family there was considerable disagreement for some time previous to the King's death between his Majesty and the Duchess of Kent.
