Viscountess Folkestone gave a concert yesterday week in aid of the funds of the Royal College of Music. The picture gallery of Stafford House, where the concert was given by permission of the Duke and Duchess of Sutherland, presented a brilliant appearance, being lighted by electric light and thronged by a large audience, which included the Prince and Princess of Wales and other distinguished persons. Upwards of 900 tickets at a guinea each were sold.
