What type of dance does Scrooge dance to at his nephew's house?

Gnomon

I've checked the text of where Scrooge goes to his nephew's house and there is no mention of him dancing: ' He turned it gently, and sidled his face in, round the door. They were looking at the table (which was spread out in great {array);} for these young housekeepers are always nervous on such points, and like to see that everything is right. 'Fred.' said Scrooge. Dear heart alive, how his niece by marriage started. Scrooge had forgotten, for the moment, about her sitting in the corner with the footstool, or he wouldn't have done it, on any account. 'Why bless my soul.' cried Fred,' who's that.' 'It's I. Your uncle Scrooge. I have come to dinner. Will you let me in, Fred.' Let him in. It is a mercy he didn't shake his arm off. He was at home in five minutes. Nothing could be heartier. His niece looked just the same. So did Topper when he came. So did the plump sister when she came. So did every one when they came. Wonderful party, wonderful games, wonderful unanimity, wonderful happiness.' Dec 11 02, 2:39 PM
