"Pray, tell me," I said to him, "what relation there is between this collection and natural history? I see nothing here representing the three kingdoms."

"What! You do not see the antediluvian kingdom, that of Sesostris and that of Semiramis? Are not those the three kingdoms?"

When I heard that answer I embraced him with an exclamation of delight, which was sarcastic in its intent, but which he took for admiration, and he at once unfolded all the treasures of his whimsical knowledge respecting his possessions, ending with the rusty blade which he said was the very knife with which Saint Peter cut off the ear of Malek.

"What!" I exclaimed, "you are the possessor of this knife, and you are not as rich as Croesus?"

"How could I be so through the possession of the knife?"

"In two ways. In the first place, you could obtain possession of all the treasures hidden under ground in the States of the Church."

"Yes, that is a natural consequence, because St. Peter has the keys."

"In the second place, you might sell the knife to the Pope, if you happen to possess proof of its authenticity."

"You mean the parchment. Of course I have it; do you think I would have bought one without the other?"

"All right, then. In order to get possession of that knife, the Pope would, I have no doubt, make a cardinal of your son, but you must have the sheath too."
