"About a milligram. Some individuals might take up to five or six, and recover. More than six milligrams would likely finish anyone, unless there was immediate medical attention—you understand, those figures refer to a pure concentration of the drug."

Callista's lips were moving also. As Edith looked to her again, she saw them shape unmistakable words: "Go away!" There would be no sound, Edith thought, even for Cecil Warner, who had taken hold of her hand and was showing the beginning of alarm. "Go away!"

"Is the drug readily soluble in alcohol?"

"Yes, Mr. Hunter."

Callista, be quiet! He can't hear you. He can't hear anyone.

"Assuming a person had taken four to five milligrams of the poison, Dr. Devens, he could still be saved by immediate medical attention?"

Stomach pump. Tannic acid I imagine, to render the poison inert. You'd give heart stimulants, say digitalis. A healthy patient would have a pretty good chance."

"Thank you, Dr. Devens. Cross examination, Mr. Warner?"

"No cross examination." But Warner was up, for once urgently quick-spoken. "Your Honor, in view of my client's exhaustion, may we have adjournment at this time?"
