One stormy night, when the rain was descending in torrents, the doctor heard a rap at his door.

It was customary with him, when called up at night to visit a patient, to ring for Sam.

But this time, the servant was nowhere to be found.

The doctor struck a light and looked for clothes; they too, were gone .-- It was twelve o'clock, and the doctor's clothes, hat, boots, and even his watch, were nowhere to be found.

Here was a pretty dilemma for a doctor to be in.
It was some time before the physician could fit himself out so as to mike the visit.
