He listened attentively to the account of his years of illness, inquired of others in the house with him, and then went to bed and to sleep.

In the morning he woke with a sense of unexplained depression.

In searching about for the cause he went over his interviews of the day before and found a doubt in his mind which he would hardly acknowledge; but by the end of the next day he said to himself: "What a fool I was to come so far without a more complete knowledge of what I was coming to! This man has been well for years and does not know it.

It is the old habit of his illness that is on him; the illness itself must have left him ten years ago." The next day--the first thing after breakfast--he took a long walk in order to make up his mind what to do, and finally decided that he had engaged to stay one month and must keep to his promise.

It would not do to tell the invalid the truth--the poor man would not believe it.
