“Just think of an automatic executioner,” said Marat, enthusiastically, “with no need of a man to set it going; which can, if the knife is changed a couple of times, cut off three hundred heads a-day!”

“And add,” said a bland, melodious voice, behind Marat, “which can cut off these heads without other sensation than a slight coolness around the neck.”

“Oh, is this you, doctor?” exclaimed Marat, turning towards a dapper little man of forty or so, whose gentle demeanor and spruce dress made a marked contrast with his host: in his hand he carried a small box such as children’s toys are kept in. “What are you bringing us?”

“A model of my machine, my dear Marat. But I see Dr. Gilbert here, unless I mistake,” said the little dandy, trying to pierce the obscurity.

“The same, sir,” said the other visitor bowing.

“Enchanted to meet you, sir; you are only too welcome, and I shall be happy to have the opinion of so distinguished a man on my invention. I must tell you, my dear Marat, that I have found a skillful carpenter, named Guidon, to make my machine on the working scale. He is dear, though, wanting five thousand five hundred francs; but no sacrifice is too great for me to make for humanity. In two months it will be built, and we can try it: I shall propose it to the Assembly. I hope you will approve of it in your excellent new paper, though, in sober earnest, the machine recommends itself, as you will see with your own eyes, Dr. Gilbert. But a few lines in the People’s Friend will do no harm.”

“Be easy on that score; it is not a few lines but a whole number that I shall dedicate to it.”

“You are too good, Marat; but I am not going to let you puff a pig in a poke.”

He took out of his pocket a much smaller box, in which a sound indicated that some little live thing or several such were fidgeting in their prison. This noise did not escape Marat’s subtle hearing.

“What have you got there?” he asked, putting out his hand towards the box.
