"But then, doctor, you do believe in these manifestations?"
"Not necessarily. But I believe that the minds of men are often very carefully, very deftly, poised, and that a little push can send them one way or the other. Have you ever balanced one billiard-ball on the top of another?"
"Yes."
"Then you know that a breath will upset it and send it rolling. Be careful. Your mind, your very nature, may be poised like that billiard-ball. Addison's may be the same. Indeed, I feel sure Addison's is. That curious dread of you which overcame him at your last sitting is a sign of it. The whole thing is wrong—bad for body and for mind."
"Perhaps. Well, we have definitely agreed to give it up."
"That's well. Eleven o'clock! I must be going. Are you doing anything to-morrow night?"
"No."
"I have got a box for this new play at the Duke's Theatre. Will you come?"
"With pleasure."
"I will ask Addison also."
