me to use! How I longed to discover the secret of some perfect lens whose magnifying power should be limited only by the resolvability of the object, and which at the same time should be free from spherical and chromatic aberrations, in short from all the obstacles over which the poor microscopist finds himself continually stumbling! I felt convinced that the simple microscope, composed of a single lens of such vast yet perfect power, was possible of construction. To attempt to bring the compound microscope up to such a pitch would have been commencing at the wrong end; this latter being simply a partially successful endeavor to remedy those very defects of the simple instrument, which, if conquered, would leave nothing to be desired.
It was in this mood of mind that I became a constructive microscopist. After another year passed in this new pursuit, experimenting on every imaginable substance, glass, gems, flints, crystals, artificial crystals formed of the alloy of various vitreous materials, in short, having constructed as many varieties of lenses as Argus had eyes, I found myself precisely where I started, with nothing gained save an extensive knowledge of glass-making. I was almost dead with despair. My parents were surprised at my apparent want of progress in my medical studies, (I had not attended one lecture since my arrival in the city,) and the expenses of my mad pursuit had been so great as to embarrass me very seriously.
I was in this frame of mind one day, experimenting in my laboratory on a small diamond, that stone, from its great refracting power, having always occupied my attention more than any other, when a young Frenchman, who lived on the floor above me, and who was in the habit of occasionally visiting me, entered the room.
I think that Jules Simon was a Jew. He had many traits of the Hebrew character: a love of jewelry, of dress, and of good living. There was something mysterious about him. He always had something to sell, and yet went into excellent society. When I say sell, I should perhaps have said peddle; for his operations were generally confined to the disposal of single articles,—a picture, for instance, or a rare carving in ivory, or a pair of duelling-pistols, or the dress of a Mexican caballero. When I was first furnishing my rooms, he paid me a visit, which ended in my purchasing an antique silver lamp, which he assured me was a Cellini,—it was handsome enough even for that,—and some other knick-knacks for my sitting-room. Why Simon should pursue this petty trade I never could imagine. He apparently had plenty of money, and had the entrée of the best houses in the city,—taking care, however, I suppose, to drive no bargains within the enchanted circle of the Upper Ten. I came at length to the conclusion that this peddling was but a mask to cover some greater object, and even went so far as to believe my young acquaintance to be implicated in the slave-trade. That, however, was none of my affair.
On the present occasion, Simon entered my room in a state of considerable excitement.
"Ah! mon ami!" he cried, before I could even offer him the ordinary salutation, "it has occurred to me to be the witness of the most astonishing things in the world. I promenade myself to the house of Madame ——— How does the little animal—le renard—name himself in the Latin?"
" Vulpes," I answered.
"Ah! yes,—Vulpes. I promenade myself to the house of Madame Vulpes."
"The spirit medium?"
"Yes, the great medium. Great Heavens! what a woman! I write on a slip of paper many of questions concerning affairs the most secret, affairs that conceal themselves in the abysses of my heart the most profound; and behold! by example! what occurs? This devil of a woman makes me replies the most truthful to all of them. She talks to me of things that I do not love to talk of to
