Amelius told Sally to wait in the cab. She saw his altered looks, and entreated him not to leave her. He promised to keep the house door open so that she could see him while he was away from her, and hastened into the hall.

“I am sorry to say I have bad, very bad, news for you,” the doctor began. “Time is of serious importance—I must speak plainly. You have heard of mistakes made by taking the wrong bottle of medicine? The poor lady upstairs is, I fear, in a dying state, from an accident of that sort. Try to compose yourself. You may really be of use to me, if you are firm enough to take my place while I am away.”

Amelius steadied himself instantly. “What I can do, I will do,” he answered.

The doctor looked at him. “I believe you,” he said. “Now listen. In this case, a dose limited to fifteen drops has been confounded with a dose of two table-spoonsful; and the drug taken by mistake is strychnine. One grain of the poison has been known to prove fatal—she has taken three. The convulsion fits have begun. Antidotes are out of the question—the poor creature can swallow nothing. I have heard of opium as a possible means of relief; and I am going to get the instrument for injecting it under the skin. Not that I have much belief in the remedy; but I must try something. Have you courage enough to hold her, if another of the convulsions comes on in my absence?”

“Will it relieve her, if I hold her?” Amelius, asked.

“Certainly.”

“Then I promise to do it.”

“Mind! you must do it thoroughly. There are only two women upstairs; both perfectly useless in this emergency. If she shrieks to you to be held, exert your strength—take her with a firm grasp. If you only touch her (I can’t explain it, but it is so), you will make matters worse.”

The servant ran downstairs, while he was speaking. “Don’t leave us, sir—I’m afraid it’s coming on again.”

“This gentleman will help you, while I am away,” said the doctor. “One word more,” he went on, addressing Amelius. “In the intervals between the fits, she is perfectly conscious; able to listen, and even to speak. If she has any last wishes to communicate, make good use of the time. She may die of exhaustion, at any moment. I will be back directly.”
