THE STREETS OF L ONDON, EACH so particular and unique to the terrified, benighted pedestrian, were, to a coach-passenger, as anonymous and same as waves on the sea. As Waterhouse, Newton, and Leibniz had sailed through them during the early hours of the morning, Daniel had teased himself with the phant’sy that they would settle the Calculus Dispute now, perhaps with Christian reconciliation or perhaps with a roadside duel in the dead of night. But Sir Isaac had made it plain that he had no intention of talking about anything, and had pretended to sleep, and shifted and glared when Leibniz and Waterhouse disturbed his repose with candle-light and chit-chat. This made perfect sense. Isaac held the upper hand in the dispute, and was going to triumph; why talk to Leibniz at all? Leibniz would have to make Newton want to talk.
