first
acquaintance; a good fellow, with a brisk voice, and an amazingly light
tread.

He began by sending Wardrop into a sort of examining room in the rear of
the suite somewhere, to take off his coat and collar. When he had gone
the doctor looked at a slip of paper in his hand.

"I think I've got it all from Mr. Burton," he said. "Of course, Mr.
Knox, this is a little out of my line; a nerve specialist has as much
business with psychotherapy as a piano tuner has with musical technique.
But the idea is Munsterburg's, and I've had some good results. I'll give
him a short physical examination, and when I ring the bell one of you
may come in. Are you a newspaper man, Mr. Knox?"

"An attorney," I said briefly.

"Press man, lawyer, or doctor," Burton broke in, "we all fatten on the
other fellow's troubles, don't we?"

"We don't fatten very much," I corrected "We live."

The doctor blinked behind his glasses.

"I never saw a lawyer yet who would admit he was making money," he said.
"Look at the way a doctor grinds for a pittance! He's just as capable as
the lawyer; he works a damn sight harder, and he makes a tenth the
income. A man will pay his lawyer ten thousand dollars for keeping him
out of jail for six months, and he'll kick like a steer if his doctor
charges him a hundred to keep him out of hell for life! Which of you
will come in? I'm afraid two would distract him."

"I guess it is Knox's butt-in," Burton conceded, "but I get it later,
Doctor; you promised."

The physical examination was very brief; when I was called in Wardrop
was standing at the window looking down into the street below, and the
doctor was writing at his desk. Behind Wardrop's back he gave me the
slip he had written.

"Test is for association of ideas. Watch length of time between
word I give and his reply. I often get hold of facts forgotten
by the patient. A wait before the answering word is given shows
an attempt at concealment."

"Now, Mr. Wardrop," he said, "will you sit here, please?"

He drew a chair to the center-table for Wardrop, and another, just
across for himself. I sat back and to one side of the patient, where I
could see Wardrop's haggard profile and every movement of the
specialist.

On the table was an electric instrument like a small clock, and the
doctor's first action was to attach to it two wires with small, black
rubber mouthpieces.

"Now, Mr. Wardrop," he said, "we will go on with the te
