"My dear child," said the doctor, looking down at Marion, "how can I tell until I've seen her? But good heavens! what's the matter with you?"

Marion had burst into a fit of laughter, and the doctor sat and looked at her in perfect amazement.

"What is the matter, child? What are you laughing at?"

But Marion laughed and laughed; throwing her head down into her muff as if to control herself, and then looking up at the doctor, and laughing harder than before.

"What's the matter with you, child?" cried the poor man, really growing uneasy. "Have you gone crazy, or was the wine too much for you?"

"It isn't that, doctor, but you—you—"

"What in the devil's the matter with me, I should like to know!"

"You've—you've—got on your nightcap!" cried Marion, as well as she could speak.

The doctor dropped the reins, and put both hands to his head. Sure enough, in the hurry of dressing he had forgotten to take off the immense bandanna handkerchief he wore tied round his head every night; and over it he had put his cloth cap, which, fitting tight to his head, left the ends of the handkerchief sticking out each side like great horns, giving an indescribably funny appearance to the doctor's jolly round face.

Now Dr. Brown, although he always considered himself privileged to say and do anything he had a mind to, was excessively particular about his toilet, and to take a moonlight drive with a young lady, with his nightcap on, was quite contrary to his usual habits. However, it was altogether too ridiculous a situation to do anything but laugh, and the doctor could enjoy a joke even against himself.
