The next witness examined was Sir Frederick Johnstone, who testified that he had gone to dine with Lady Mordaunt at the Alexandra Hotel, in obedience to a request which she made by letter, to that effect. The dinner was a tete-a-tete one, (no one being present but Sir Frederick and Lady Mordaunt) in a private room, and it lasted from four o'clock in the afternoon until twelve o'clock at night. Sir Frederick acknowledged that the dinner took place without the knowledge of Sir Charles Mordaunt, and that he never told the latter of the circumstance afterward, although a visitor at Walton Hall.
