to me twenty years ago,
you will see that my claim that I am twenty years in advance of my
generation is well founded. I shall not enter into the many theories
advanced to explain the phenomenon of acquired immunity from disease,
because it would be unprofitable to take up such a discussion, while
you are waiting to hear what concerns you more closely. Suffice it to
say, that various scientists have learned that immunity may be
produced in a previously susceptible animal by the injection of
various preparations. But in each instance, the injection is expected
to produce immunity from only one disease. My own studies were at
first in this direction, and I have succeeded not only in learning how
to prevent each malady separately, but what is far better, I have
discovered a method by which I can render an individual immune to all
zymotic diseases."

"Then, indeed, are you a wizard!"

"Yes, because I do that which transcends the powers and knowledge of
my fellows! But mark my prophecy! Just so surely as the scientific
investigators of to-day have learned what I knew twenty years ago, so
will the investigators of the future master the secrets which now are
known only to myself. I am a wizard, perhaps, but I am a modern
wizard. There is nothing of the supernatural about my methods. But now
let me be more explicit. What Chauvau did with sheep, I have done with
the human being."

"What! You have dared to make such an experiment?"

"Dared? Emanuel Medjora dares all things, in the pursuit of
knowledge!"

The man had arisen as he warmed to his subject, and now, as he drew
himself up erect, he towered over the Judge as a giant might.

"Listen, and be convinced. I discovered a precious preparation, which,
if injected at the proper time would, in my opinion, bring me the
consummation of my dreams. A single fluid, which would produce
immunity from all diseases. Just after you had procured my acquittal,
and thus saved me and my learning for the benefit of the world, you
were kind enough to intrust me with the care of your wife's health."

"I had no hesitation in doing so. I had faith in you."

"The result has shown that your faith was well founded. At the proper
time, I injected the preparation which I had formulated, into the arm
of your wife."

"You did that?"

"I did. You will recall the fact that from being feeble she began to
gain strength. Periodically I repeated my injections, and renewed
vigor coursed through her
