"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 Réné.

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

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