“Yes, in a sort of lethargy. That’s what makes the case a puzzle. Won’t you order a hot-water bottle, somebody?”

Hetzel left the room. In a moment he brought the bottle of hot water. The doctor applied it to Arthur’s feet.

“And the chopped ice?” Hetzel inquired.

The doctor placed his hand upon Arthur’s brow.

“N—no; we won’t use the chopped ice yet a while,” he answered.

By and by a bell rang down-stairs. A little later Mrs. Hart came in.

“Our doctor—Dr. Letzup—is here,” she announced.

Dr. Letzup entered.

“I suppose you medical men would like to be left alone?” said Mr. Flint.

“Yes, I guess so,” said the hospital-doctor.
