For weeks I have not added a word to this record. But now I have looked upon death, and I must write. There is no one to confide in but this little book, stained by so many tears, confident of so many sorrows, so many disappointments. Prof. Darmstetter is dead. Dead, but not by my fault. I was not the thousandth part to blame. Yet I tremble like a leaf to think of it. I shall get no sleep to-night and to-morrow look like a fright to pay for it--no! I can never do that now, thank God! Thank God for that! Yes, I'm glad; when I try to be calm, I am glad he's dead--no, not that--sorry he's dead, of course, but glad that my rights are safe--when I am calm. But I can't be calm; it was too horrible! It happened yesterday in the laboratory; we were alone together. I have seldom been to the laboratory of late, but I had begun to suspect that the Professor was planning treachery, preparing to try the Bacillus upon other women. He had been so impatient because I had not gone often enough, that he might make his records, his comparisons, his tests--I don't know what flummery. All at once he ceased his importunities; some instinct taught me that he was about to seek a more tractable subject. I was resolved that if he did contemplate such injustice, I should put a stop to it. And I went to watch him. Was that wrong? Why, he had promised me that I should have pioneer's rights in the realm of beauty. Sole possession was to be my reward? I had the right to hold him to his promise. But I didn't think-- Yesterday I spoke to Prof. Darmstetter. That was how it came about. He had looked disconcerted at my appearance in the laboratory, and my suspicions had suddenly grown to certainty. I said to him:-- "I wish to see you alone." A guilty look came to his face. I was watching him as he had watched me before the great change, and when he started at my words I knew he was thinking of playing me false; his conscience must have warned him that I had read his thoughts. But he knew that my strength was greater than his and he bowed assent. When the other girls had gone--some of them with frightened looks at me, as if mine were the devil's beauty they tell about--and when Prof. Darmstetter was ready to begin his own work, I faced him with a challenge:-- "Prof. Darmstetter, you are about to break your word." "You are mistaken," he said; but he could not face my look. "I am not mistaken; you are planning to try the Bacillus upon other women, and you promised that I should be first."
