"After all, my nephew will be much better cared for there," he said to himself, "and I shall be much easier in mind. Every one admits that the best way to divert a lunatic's mind is to give him a change of scene, so I am only doing my duty."

It was with this very thought in his mind that he fell asleep just before Francis bound his hands. What an awakening was his!

The doctor entered with a smiling excuse for his long delay. Francis rose, laid his book on the table, and proceeded with volubility to explain the business that had brought him there.

"It is my uncle on my mother's side that I desire to intrust to your care," he began. "He is, as you see, a man between forty-five and fifty years of age, accustomed to manual labor and the economy and privations of a humble and busy life; moreover, he was born of healthy, hard-working parents, in a family where no case of mental aberration was ever before known. You will not, therefore, be obliged to contend with a hereditary malady. His is probably one of the most peculiar cases of monomania that has ever come under your observation. His mood changes almost instantaneously from one of extreme gaiety to profound melancholy. In fact, it is a strange compound of monomania and melancholy."

"He has not lost his reason entirely?"

"Oh, no; he is never violent; in fact, he is insane upon one subject only."

"What is the nature of his malady?"

"Alas! the besetting sin of the age, sir; cupidity. He has become deeply imbued with the spirit of our times. After working hard from childhood, he finds himself still comparatively poor, while my father, who began life under like circumstances, was able to leave me a snug little fortune. My uncle began by being envious of me; then the thought occurred to him that, being my only relative, he would become my heir in case of my death, and my guardian in case I became insane; and as it is very easy for a weak-minded person to believe whatever he desires to believe, the unfortunate man soon persuaded himself that I had lost my reason. He has told everybody that this is the case; and he will soon tell you so. In the carriage, though his hands were tied, he really believed that it was he who was bringing me here."

"When did this malady first show itself?"

"About three months ago. He came to my concierge and said to him, in the wildest manner: 'Monsieur Emmanuel, you have a daughter. Let me in, and then come and assist me in binding my nephew.'"
