"She went to Colnaghi’s and ordered the finest portrait of him that art had produced, and credit could supply. She chose that famous one in which the best of monarchs is represented in a frockcoat with a fur collar, and breeches and silk stockings, simpering on a sofa from under his curly brown wig. She had him painted in a brooch and wore it—indeed she amused and somewhat pestered her acquaintance with her perpetual talk about his urbanity and beauty. "
