“ The Emperor wore a scarlet uniform, the evening dress of the regiment of chevaliers gardes; the Empress (led in by the Duke) a robe of crimson coloured silk, richly ornamented with diamonds and pearls. She had a necklace of diamonds, with a row across the shoulders, of superior size and beauty, most of them appearing half-an-inch in diameter, while strings of them of inferior magnitude were entwined among her hair. She looked extremely well, and, throughout the evening, was all condescension and amiableness, seeming highly to enjoy the animated scene. ”
