"I'm not going to deny anything of the sort," said I; "she did sell me glass, and of the commonest kind. I am now seeking an undiscovered superlative. The biggest fool in London is no designation for me."

"Ah," said he, "you should take it quietly. She's done a complete dozen of us at the game. That paraphernalia which Jack Lucas rigged up in her conservatory for her is the medium, I fancy. Lucas, you know, is a professor or something at Emmanuel, Cambridge. He taught her all that jargon about crystals."

"But," said I, as I pitched her glass into the fireplace, "what I want to know is, how did I come to think that the stuff was real? I could have sworn to it."

"So could we all," he replied, with a great burst of laughter; "but I'll tell you in a word—she hypnotized you. I always said you were a grand subject."

I looked him in the face for a minute, during which he made an heroic attempt to be serious. But it was too much for him. Presently he gave one great shout of hilarity which you could have heard half-way down the street, and then rolled about in his chair uncontrollably.

"You seem to find it amusing," said I, "but I fail to catch the point."

"You'll be seeing it by-and-by," said he, and at that he went off to the club to be first with it.

THE END.
