The mixture immediately foamed up.

"Doctor, do you know the drug which has been used on my partner?" asked Old King Brady.

"Perfectly well," replied the doctor.

"Does it act on the heart?" demanded the surgeon.

"Both on the heart and lungs," was the reply, and this was all they could get out of High Lung, who now proceeded to administer the mixture to Harry.

It promptly did its work. Within ten minutes Young King Brady opened his eyes.

"Oh! I have had such queer dreams!" he muttered.

"Dream some more," said High Lung; and taking Old King Brady aside he said:

"They gave him an overdose. He was almost gone. He must not be moved out of here under two days. I shall want to see him twice again."

"The case is yours," said Old King Brady. "I shall stay right here with him."
