"With what sort of poison?"

"With mineral poison, I think."

"Can you ascertain positively that he has been poisoned?"

"Yes, certainly, by opening and examining the stomach."

"Open it. I wish there to be no doubt."

"I must call some one to a.s.sist me."

"I will help you," said Charles.

"You, sire!"

"Yes. If he has been poisoned, what symptoms shall we find?"

"Red blotches and herborizations in the stomach."

"Come, then," said Charles, "begin."

With a stroke of the scalpel Rene opened the hound's body and with his two hands removed the stomach, while Charles, one knee on the floor, held the light with clenched and trembling hand.

"See, sire," said Rene; "here are evident marks. These are the red spots I spoke of; as to these b.l.o.o.d.y veins, which seem like the roots of a plant, they are what I meant by herborizations. I find here everything I looked for."

"So the dog was poisoned?"

"Yes, sire."

"With mineral poison?"

"In all probability."

"And what symptoms would a man have who had inadvertently swallowed some of the same poison?"

"Great pain in the head, internal burning as if he had swallowed hot coals, pains in the bowels, and vomiting."

"Would he be thirsty?" asked Charles.

"Intensely thirsty."

"That is it! that is it!" murmured the King.

"Sire, I seek in vain for the motive for all these questions."

"Of what use to seek it? You need not know it. Answer my questions, that is all."

"Yes, sire."

"What is the antidote to give a man who may have swallowed the same substance as my dog?"

Rene reflected an instant.

"There are several mineral poisons," said he; "and before answering I should like to know what you mean. Has your Majesty any idea of the way in which your dog was poisoned?"

"Yes," said Charles; "he chewed the leaf of a book."

"The leaf of a book?"

"Yes."

"Has your Majesty this book?"

"Here it is," said Charles, and, taking the volume from the shelf where he had placed it, he handed it to Rene.

The latter gave a start of surprise which did not escape the King.

"He ate a leaf of this book?" stammered Rene.

"Yes, this one," and Charles pointed to the torn page.

"Will you allow me to tear out another, sire?"

"Do so."

Rene tore out a leaf and held it over the candle. The paper caught fire, filling the room with a strong smell of garlic.

"He has been poisoned with a preparation of a.r.s.enic," said he.

"You are sure?"

"As sure as if I had prepared it myself."

"And the antidote?"

Rene shook his head.

"What!" said Charles in a hoa.r.s.e voice, "you know no remedy?"

"The best and most efficacious is the white of eggs beaten in milk; but"--

"But what?"

"It must be administered at once; otherwise"--

"Otherwise?"

"Sire, it is a terrible poison," said Rene, again.
