High Lung then ordered Alice from the room and Harry was stripped.
The Chinese doctor's treatment certainly was peculiar at the start.
He climbed in the bed and lay down flat on top of Harry, breathing in his mouth and at the same time kneading his back with his hands.
The ambulance surgeon looked on with no attempt to conceal his disgust.
At last the Chinaman got off the bed and began opening a bag which he had brought along.
"Examine him now, Doctor," he said.
The surgeon did so.
"Upon my word it is a fact that he is breathing," he admitted. "I wouldn't have believed it."
The Chinese doctor then produced just such another box and vial as the old detective had seen the Chinamen handling in the secret den.
Calling for a cup he put into it a portion of a grayish powder out of the box and poured a bright blue liquid upon it out of the vial.
