“Oh, yes, sir, a great deal too much—and alone.”

“Good. I thought so. What do you wear on your head at night?”

“An embroidered night-cap, and sometimes a handkerchief over it.”

“Don’t you feel a heat there, a slight perspiration?”

“How can I, when I’m asleep?”

“Don’t you find your night-cap moist on your forehead, when you wake up?”

“Sometimes.”

“Capital. Give me your hand.”

The doctor takes out his watch.

“Did I tell you that I have a vertigo?” asks Caroline.
