Up-stairs Horace paced the floor of his study. From time to time he glanced toward Berkeley waiting there in suave dark-red reputability, an open book lying suggestively on his cushions. And then he found that his circuit of the floor was bringing him each time nearer to Hume. There was something about Hume that was strangely and inexpressibly different. The diaphanous form still seemed hovering near, and had Horace sat there he would have felt as if he were sitting on a lady's lap.
