"'That is very natural; no one lightly undertakes such a thing,' continued the other. 'So much greater will be our triumph if the operation succeeds. I hope to show you, dear colleague, that although we are thinking of taking that man's blood, even to the last drop, in a few hours we shall set him on his feet again.'
"'Just so! I do not see why we should not succeed. At any rate, in the interests of science we should prove in a practical manner the correctness of our theory.'
"'And this proof, dear friend, we will undertake without delay. Let me just repeat my instructions, for we cannot go to work too carefully to preserve the life of this man. I will open a vein in his thigh, and measure exactly the quantity of blood which flows out, at the same time watching the beating of the heart. Under ordinary circumstances nothing could possibly save him; but just before the extinction of the last spark of life, we will insert the warm blood of a living rabbit into his veins, as we have already arranged. If my theory is right, the pulsation of the heart will then gradually increase in strength and rapidity. At the same time, it is important to protect his limbs from cold and stiffness, which will naturally take place with the loss of all arterial blood.'
"The conversation of the two doctors overwhelmed me with deadly terror. I could scarcely believe I was really awake, and not the victim of some cruel nightmare.
"The fact remained, however, that I lay helpless on the dissecting-table, that a threatening skeleton stood in the corner of the room, and, above all, that terrible conversation which I had to listen to in silence filled me with a fear such as I had never before experienced. Involuntarily the thought forced itself upon me that I was at the mercy of two infatuated doctors, to whose mad theory I should here fall the victim.
"I said to myself that no doctor with a sound mind would propose such a frightful and murderous experiment upon a living man.
"I struggled to get free."
"The two doctors now approached the dissecting-table, and looked calmly into my face; then, smiling, took off their coats, and tucked up their sleeves. I struggled to get free, as only a desperate man under such extraordinary circumstances could have struggled. In vain. Their long-acquired experience knew how to render me completely helpless, and, to their satisfaction, I could not even make a sound.
"Dr. Engler now turned to a side-table, and I saw him open a chest of surgical instruments and take out a lancet, with which he returned to me. He at once removed the covering from my right thigh, and although I lay bound to the table in such a way that I could not see my limbs, I was able to watch the doctor busied with his preparations.
"Directly after removing the cloth I felt a prick in the side of my leg, and at once felt the warm blood rush forth and trickle down my leg. The conviction that he had opened the principal vein in the thigh would have sufficed to shake the strongest nerves.
"'There is no danger,' said Dr. Engler, looking into my staring, protruding eyes with terrible calmness. 'You will not die, my good man. I have only opened an artery in your thigh, and you will experience all the sensations of bleeding to death. You will get weaker and weaker, and finally, perhaps, lose all consciousness, but we shall not let you die. No, no!
