The young man who presented himself on the morning just mentioned was a handsome fellow, yet of evident weak character and unhealthy temperament—sensitive, and easily exalted or depressed. A single glance convinced the surgeon that his visitor was seriously affected in mind, for there was never bolder skull-grin of melancholia, fixed and irremediable.

A stranger would not have suspected any occupancy of the house. The street door—old, warped, and blistered by the sun—was locked, and the small, faded-green window-blinds were closed. The young man rapped at the door. No answer. He rapped again. Still no sign. He examined a slip of paper, glanced at the number on the house, and then, with the impatience of a child, he furiously kicked the door. There were signs of numerous other such kicks. A response came in the shape of a shuffling footstep in the hall, a turning of the rusty key, and a sharp face that peered through a cautious opening in the door.

"Are you the doctor?" asked the young man.

"Yes, yes! Come in," briskly replied the master of the house.

The young man entered. The old surgeon closed the door and carefully locked it. "This way," he said, advancing to a rickety flight of stairs. The young man followed. The surgeon led the way up the stairs, turned into a narrow, musty-smelling corridor at the left, traversed it, rattling the loose boards under his feet, at the farther end opened a door at the right, and beckoned his visitor to enter. The young man found himself in a pleasant room, furnished in antique fashion and with hard simplicity.

"Sit down," said the old man, placing a chair so that its occupant should face a window that looked out upon a dead wall about six feet from the house. He threw open the blind, and a pale light entered. He then seated himself near his visitor and directly facing him, and with a searching look, that had all the power of a microscope, he proceeded to diagnosticate the case.

"Well?" he presently asked.

The young man shifted uneasily in his seat.

"I—I have come to see you," he finally stammered, "because I'm in trouble."

"Ah!"
