I had been waiting a long time without a patient, when a shuffling sound was heard on the stairs, and a heavy step approaching the door.
Next came a knock.
Instead of calling out, "Come in!" I was so pleased at the prospect of a patient, that I rose from my seat and opened the door, myself.
I started back in surprise. For in the heavy, lumbering figure of the new arrival I recognized Prof. Poppendorf.
"Prof. Poppendorf!" I exclaimed.
"Ja, doctor, it is I. May I come in?"
"Certainly."
Supposing that he had come to consult me on the subject of his health, I began to wonder from what disease he was suffering. Remembering his achievements at the table I fancied it might be dyspepsia.
The Professor entered the room, and sank into an armchair, which he quite filled from side to side.
"I suppose you are surprised to see me, Herr Doctor," began the Professor.
