“When you pay me a visit in my cell, my young friend,” said he, “I will show you an entire work, the fruits of the thoughts and reflections of my whole life; many of them meditated over in the shades of the Colosseum at Rome, at the foot of St. Mark’s column at Venice, and on the borders of the Arno at Florence, little imagining at the time that they would be arranged in order within the walls of the Château d’If. The work I speak of is called A Treatise on the Possibility of a General Monarchy in Italy , and will make one large quarto volume.”

“And on what have you written all this?”

“On two of my shirts. I invented a preparation that makes linen as smooth and as easy to write on as parchment.”

“You are, then, a chemist?”

“Somewhat; I know Lavoisier, and was the intimate friend of Cabanis.”
