"Then it is time to take it again."

"I must go to the window, to see how much to pour out. How much do you usually take?"

Paul Morton took the bottle and the glass to the window. As he stood there he was out of the observation of the patient. He poured out the required quantity of the cordial into the glass; but after doing so, he slyly added a small quantity of powder from a paper which he drew from his vest pocket. He put the paper back, and reappeared at the bedside holding the glass in his hand.
"I think I have poured out the right quantity," he said; but his voice was constrained, and there was a pallor about his face.
