Among the many important entertainments given by members of the English aristocracy in honour of the sixtieth year of the reign of Queen Victoria, was a Costume Ball at Devonshire House, Piccadilly, on July 2nd, 1897, when the Duke and Duchess of Devonshire received nearly all the members of the Royal Family, many distinguished guests from the Colonies, and members of the Corps Diplomatique. This historic mansion was built for the third Duke of Devonshire, and it was here that Georgiana, the beautiful Duchess of Devonshire, held her Court. It contains a fine suite of reception rooms on the first floor; a gallery of pictures, in which the old masters are well represented; and extensive grounds in the rear, which on this occasion were decorated with thousands of Chinese lanterns and fairy lamps. The principal feature of the ball was a grand procession of the guests, headed by the Duke and Duchess of Devonshire, the former personating Charles V. of Germany, and the latter attired with Oriental magnificence as Zenobia, Queen of Palmyra, in a robe of silver tissue wrought with jewels.
