Raeburn, seeing that she was not in the least interested in the discussion of the future of electricity, left the professor to continue it with Tom, and began to talk to her about the loss of her purse, and to tell her of various losses which he had had. But Rose had the mortifying consciousness that all the time he talked he was listening to the conversation between Erica and M. Noirol. As far as Rose could make out it was on French politics; but they spoke so fast that her indifferent school French was of very little service to her. By and by Raeburn was drawn into the discussion and Rose was left to amuse herself as well as she could by listening to a rapid flow of unintelligible French on one side, and to equally unintelligible scientific talk on the other. By and by this was merged into a discussion some recent book. They seemed to get deeply interested in a dispute as to whether Spinoza was or was not at any time in his life a Cartesian. Rose really listened to this for want of something better to do, and Raeburn, thinking that he had been neglecting her, and much relieved at the thought that he had at length found some point of mutual interest, asked her whether she had read the book in question. “Oh, I have no time for reading,” said Rose. He looked a little amused at this statement. Rose continued: “Who was Spinoza? I never heard any of his music.” “He was a philosopher, not a composer,” said Raeburn, keeping his countenance with difficulty. “What dreadfully learned people you are!” said Rose with one of her arch smiles. “But do tell me, how can a man be a Cartesian? I've heard of Cartesian wells, but never--” She broke off for this was quite too much for Raeburn's gravity; he laughed, but so pleasantly that she laughed too. “You are thinking of artesian wells, I fancy,” he said in his kindly voice; and he began to give her a brief outline of Descartes' philosophy, which it is to be feared she did not at all appreciate. She was not sorry when Erica appealed to him for some disputed fact, in which they all seemed most extraordinarily interested, for when the discussion had lasted some minutes, Tom went off in the middle of dinner and fetched in two or three bulky books of reference; these were eagerly seized upon, to the entire disregard of the pudding which was allowed to get cold. Presently the very informal meal was ended by some excellent coffee in the place of the conventional dessert, after which came a hurried dispersion as they were all going to some political meeting at the East End. Cabs were unattainable and, having secured a couple of link-boys, they set off, apparently in excellent spirits. “Fancy turning out on such a night as this!” said Rose, putting her arm within Erica's. “I am so glad you are not going for now we can really have a cozy talk. I've ever so much to tell you.”
