of one of those incoherent verses, and, fixing my eyes on him with a quiet smile, said, “Simon, I have deceived you. I learned your secret this evening. You may as well be frank with me. Mrs. Vulpes—or rather, one of her spirits—told me all.”

He started with horror. His intoxication seemed for the moment to fade away, and he made a movement toward the weapon that he had a short time before laid down. I stopped him with my hand.

“Monster!” he cried passionately, “I am ruined! What shall I do? You shall never have it! I swear by my mother!”

“I don’t want it,” I said; “rest secure, but be frank with me. Tell me all about it.”

The drunkenness began to return. He protested with maudlin earnestness that I was entirely mistaken—that I was intoxicated; then asked me to swear eternal secrecy, and promised to disclose the mystery to me. I pledged myself, of course, to all. With an uneasy look in his eyes, and hands unsteady with drink and nervousness, he drew a small case from his breast and opened it. Heavens! How the mild lamplight was shivered into a thousand prismatic arrows as it fell upon a vast rose-diamond that glittered in the case! I was no judge of diamonds, but I saw at a glance that this was a gem of rare size and purity. I looked at Simon with wonder and—must I confess it?—with envy. How could he have obtained this treasure? In reply to my questions, I could just gather from his drunken statements (of which, I fancy, half the incoherence was affected) that he had been superintending a gang of slaves engaged in diamond- washing in Brazil; that he had seen one of them secrete a diamond, but, instead of informing his employers, had quietly watched the negro until he saw him bury his treasure; that he had dug it up and fled with it, but that as yet he was afraid to attempt to dispose of it publicly—so valuable a gem being almost certain to attract too much attention to its owner’s antecedents—and he had not been able to discover any of those obscure channels by which such matters are conveyed away safely. He added that, in accordance with oriental practice, he had named his diamond with the fanciful title of “The Eye of Morning.”

While Simon was relating this to me, I regarded the great diamond attentively. Never had I beheld anything so beautiful. All the glories of light ever imagined or described seemed to pulsate in its crystalline chambers. Its weight, as I learned from Simon, was exactly one hundred and forty carats. Here was an amazing coincidence. The hand of destiny seemed in it. On the very evening when the spirit of Leeuwenhoek communicates to me the great secret of the microscope, the priceless means which he directs me to employ start up within my easy reach! I determined, with the most perfect deliberation, to possess myself of Simon’s diamond.

I sat opposite to him while he nodded over his glass and calmly revolved the whole affair. I did not for an instant contemplate so foolish an act as a common theft, which would of course be discovered, or at least necessitate flight and concealment, all of which must interfere with my scientific plans. There was but one step to be taken—to kill Simon. After all, what was the life of a little peddling Jew in comparison with the interests of science? Human beings are taken every day from the condemned prisons to be experimented on by surgeons. This man, Simon, was by his own confession a criminal, a robber, and I believed on my soul a murderer. He deserved death quite as much as any felon condemned by the laws: why should I not, like government, contrive that his punishment should contribute to the progress of human knowledge?

The means for accomplishing everything I desired lay within my reach. There stood upon the mantelpiece a bottle half full of French laudanum. Simon was so occupied with his diamond, which I had just restored to him, that it was an affair of no difficulty to drug his glass. In a quarter of an hour he was in a profound sleep.

I now opened is waistcoat, took the diamond from the inner pocket in which he had placed it, and removed him to the bed, on which I laid him so that his feet hung down over the edge. I had possessed myself of the Malay creese, which I held in my right hand, while with the other I discovered as accurately as I could by pulsation the exact locality of the heart. It was essential that all the aspects of his death should
