"Yes," he said, "I did."

"You were going down town, weren't you?"

"Yes."

"On business?"

"Yes," he said, bewildered.

"My business down town," he said very slowly, "was with an officer of the Smithsonian Institution who had come on from Washington to see something which I had brought with me from Florida."

"Would you mind telling me what it was you brought with you from Florida?" she asked wistfully.

"No. It was malaria."
