That gentleman smiled and shook his head.
"It is a desperate chance," continued Entrefort, "and is a novel case in surgery; but it is the only chance. The fact that the weapon is a stiletto is the important point--a stupid weapon, but a blessing to us now. If the assassin had known more she would have used----"
Upon his employment of the noun "assassin" and the feminine pronoun "she," both Arnold and I started violently, and I cried out to the man to stop.
"Let him proceed," said Arnold, who, by a remarkable effort, had calmed himself.
"Not if the subject is painful," Entrefort said.
"It is not," protested Arnold; "why do you think the blow was struck by a woman?"
"Because, first, no man capable of being an assassin would use so gaudy and valuable a weapon; second, no man would be so stupid as to carry so antiquated and inadequate a thing as a stiletto, when that most murderous and satisfactory of all penetrating and cutting weapons, the bowie-knife, is available. She was a strong woman, too, for it requires a good hand to drive a stiletto to the guard, even though it miss the sternum by a hair's breadth and slip between the ribs, for the muscles here are hard and the intercostal spaces narrow. She was not only a strong woman, but a desperate one also."
"That will do," said Arnold. He beckoned me to bend closer. "You must watch this man; he is too sharp; he is dangerous."
"Then," resumed Entrefort, "I shall tell you what I intend to do. There will undoubtedly be inflammation of the aorta, which, if it persist, will cause a fatal aneurism by a breaking down of the aortal walls; but we hope, with the help of your youth and health, to check it.
"Another serious difficulty is this: With every inhalation, the entire thorax (or bony structure of the chest) considerably expands. The aorta remains stationary. You will see, therefore, that as your aorta and your breast are now held in rigid relation to each other by the stiletto, the chest, with every inhalation, pulls the aorta forward out of place about half an inch. I am certain that it is doing this, because there is no indication of an escape of arterial blood into the thoracic cavity; in other words, the mouths of the two aortal wounds have seized upon the blade with a firm hold and thus prevent it from slipping in and out. This is a very fortunate occurrence, but one which will cause pain for some time. The aorta, you may understand, being made by the stiletto to move with the breathing, pulls the heart backward and forward with every breath you take; but that organ, though now undoubtedly much surprised, will accustom itself to its new condition.
