Having seen all the high society the night before, I resolved to see all the low to-night, and went to Musard’s ball—a most curious scene; two large rooms in the rue St. Honoré almost thrown into one, a numerous and excellent orchestra, a prodigious crowd of people, most of them in costume, and all the women masked. There was every description of costume, but that which was the most general was the dress of a French post-boy, in which both males and females seemed to delight. It was well-regulated uproar and orderly confusion. When the music struck up they began dancing all over the rooms; the whole mass was in motion, but though with gestures the most vehement and grotesque, and a licence almost unbounded, the figure of the dance never seemed to be confused, and the dancers were both expert in their capers and perfect in their evolutions.
