Frau Schimmel made an end of his doubt, for she could not bring herself to stand by patiently and have the child confused by such extraordinary sentiments. She interrupted the doctor: "Little Zeno finds his pleasure in very different ways, don't you, my lamb? You would rather have your father send you to market with Frau Schimmel who buys cherries for you, wouldn't you? Cherries are better for children than 'true love,' and all the other nonsense that men worry themselves about." The doctor only laughed and said "One day he will learn for himself what his father meant, and if you wish to buy him cherries, you good old soul, take him along with you and pick out the finest. You might also go to the Nuremberg shop and let him choose the most beautiful horse, and whatever else among the toys that he wishes for, no matter how expensive it may be; for I owe it in part to my boy that I have attained my object, and I must hurt him a bit more. But don't be afraid! He will hardly feel it." What did that remarkable man have in mind? Certainly, no good! As Frau Schimmel felt that she stood in the place of a mother to her darling, she demanded respectfully what the doctor meant to do to the child. He answered in some embarrassment, and without looking at the old lady; "It is because I have need of a larger quantity of the elixir. If I were to bleed another child--and bleeding is good for every one, big or little--they would accuse me of practising the black arts and perhaps, after their fashion of making a mountain out of a molehill, would denounce me as an infanticide. Therefore the boy must spare a few more drops of his blood, and he will do so gladly if he receives something pretty as a reward. I am very skilful and can draw the blood without hurting him." When, however, Frau Schimmel clasped her hands, and Zeno, whimpering, hid his face in her skirts, the doctor hastened to add: "There, there, I am not going to do it at once, and perhaps it is just as well that I should experiment with my own blood first. So take the boy out and buy him the finest plaything you can find, and leave a message at Herr Winckler's; he is to come to-day to The Three Kings, for I have something very important to communicate to him." The old lady was very glad to get the child beyond the reach of his father. His happiness was as incomprehensible to her, as his design on the blood of his child was dreadful, and she led the boy forth quickly. The doctor, however, went into the laboratory with wavering steps, and in the next half hour prepared more of the elixir into which he mixed some of his own blood. The effect was the same as if he had used the blood of his child. This delighted him so much that he fairly beamed with pleasure. But even then he gave himself no rest. He took the elixir which he had made the day before into the library, and there he wrote and wrote.
