I can not at all describe the effect that these extraordinary
communications had upon me. I felt completely bewildered. No biological
theory could account for the _discovery_ of the lens. The medium might,
by means of biological _rapport_ with my mind, have gone so far as to
read my questions and reply to them coherently. But biology could
not enable her to discover that magnetic currents would so alter the
crystals of the diamond as to remedy its previous defects and admit of
its being polished into a perfect lens. Some such theory may have
passed through my head, it is true; but if so, I had forgotten it. In
my excited condition of mind there was no course left but to become a
convert, and it was in a state of the most painful nervous exaltation
that I left the medium's house that evening. She accompanied me to
the door, hoping that I was satisfied. The raps followed us as we went
through the hall, sounding on the balusters, the flooring, and even the
lintels of the door. I hastily expressed my satisfaction, and escaped
hurriedly into the cool night air. I walked home with but one thought
possessing me--how to obtain a diamond of the immense size required. My
entire means multiplied a hundred times over would have been inadequate
to its purchase. Besides, such stones are rare, and become historical. I
could find such only in the regalia of Eastern or European monarchs.

There was a light in Simon's room as I entered my house. A vague
impulse urged me to visit him. As I opened the door of his sitting-room
unannounced, he was bending, with his back toward me, over a Carcel
lamp, apparently engaged in minutely examining some object which he held
in his hands. As I entered, he started suddenly, thrust his hand into
his breast pocket, and turned to me with a face crimson with confusion.

"What!" I cried, "poring over the miniature of some fair lady? Well,
don't blush so much; I won't ask to see it."

Simon laughed awkwardly enough, but made none of the negative
protestations usual on such occasions. He asked me to take a seat.

"Simon," said I, "I have just come from Madame Vulpes."

This time Simon turned as white as a sheet, and seemed stupefied, as
if a sudden electric shock had smitten him. He babbled some incoherent
words, and went hastily to a small closet where he usually kept his
liquors. Although astonished at his emotion, I was too preoccupied with
my own idea to pay much attention to anything els
