“You say ‘Well!’ as if you did not know!” I exclaimed half-angrily, half-laughingly.  “These fish have helped me to understand a great deal, I assure you.  Your brother must have discovered the seed or commencement of electrical organs like those described, in the human body; and he has cultivated them in you and in himself, and has brought them to a high state of perfection.  He has cultivated them in Raffaello Cellini, and he is beginning to cultivate them in me, and I hope most sincerely he will succeed.  I think his theory is a magnificent one!”

Zara gazed seriously at me, and her large eyes seemed to grow darker with the intensity of her thought.

“Supposing you had reasoned out the matter correctly,” she said—­ “and I will not deny that you have done a great deal towards the comprehension of it—­have you no fear? do you not include some drawbacks in even Casimir’s learning such a secret, and being able to cultivate and educate such a deadly force as that of electricity in the human being?”

“If it is deadly, it is also life-giving,” I answered.  “Remedies are also poisons.  You laid the Prince senseless at your feet, but your brother raised him up again.  Both these things were done by electricity.  I can understand it all now; I see no obscurity, no mystery.  And oh, what a superb discovery it is!”

Zara smiled.

“You enthusiast!” she said, “it is nothing new.  It was well known to the ancient Chaldeans.  It was known to Moses and his followers; it was practised in perfection by Christ and His disciples.  To modern civilization it may seem a discovery, because the tendency Of all so-called progress is to forget the past.  The scent of the human savage is extraordinarily keen—­keener than that of any animal—­he can follow a track unerringly by some odour he is able to detect in the air.  Again, he can lay back his ears to the wind and catch a faint, far-off sound with, certainty and precision, and tell you what it is.  Civilized beings have forgotten all this; they can neither smell nor hear with actual keenness.  Just in the same way, they have forgotten the use of the electrical organs they all indubitably possess in large or minute degree.  As the muscles of the arm are developed by practice, so can the wonderful internal electrical apparatus of man be strengthened and enlarged by use.  The world in its youth knew this; the world in its age forgets, as an old man forgets or smiles disdainfully at the past sports of his childhood.  But do not let us talk any more to-night.  If you think your ideas of me are correct—–­”

“I am sure they are!” I cried triumphantly.

Zara held out her arms to me.

“And you are sure you love me?” she asked.

I nestled into her embrace and kissed her.

“Sure!” I answered.  “Zara, I love and honour you more than any woman I ever met or ever shall meet.  And you love me—­I know you do!”

“How can I help it?” she said.  “Are you not one of us?  Good-night, dearest!  Sleep well!”
