"I suppose you consider him quite out of danger now?"

"Oh, not at all. I think we can pull him round if we persevere, but he must not be allowed to sink back into a state of coma. We must keep him on the move until the effects of the drug have really passed off. If you will put him into his dressing-gown we will walk him up and down the room for a while."

"But is that safe?" Mr. Weiss asked anxiously.

"Quite safe," I answered. "I will watch his pulse carefully. The danger is in the possibility, or rather certainty, of a relapse if he is not kept moving."

With obvious unwillingness and disapproval, Mr. Weiss produced a dressing-gown and together we invested the patient in it. Then we dragged him, very limp, but not entirely unresisting, out of bed and stood him on his feet. He opened his eyes and blinked owlishly first at one and then at the other of us, and mumbled a few unintelligible words of protest; regardless of which, we thrust his feet into slippers and endeavoured to make him walk. At first he seemed unable to stand, and we had to support him by his arms as we urged him forward; but presently his trailing legs began to make definite walking movements, and, after one or two turns up and down the room, he was not only able partly to support his weight, but showed evidence of reviving consciousness in more energetic protests.

At this point Mr. Weiss astonished me by transferring the arm that he held to the housekeeper.

"If you will excuse me, doctor," said he, "I will go now and attend to some rather important business that I have had to leave unfinished. Mrs. Schallibaum will be able to give you all the assistance that you require, and will order the carriage when you think it safe to leave the patient.
