Maxon listened to the narration in silence. When von Horn had finished, he cautioned him against divulging to Virginia anything that took place within the inner campong. “She is only a child,” he said, “and would not understand the importance of the work we are doing. All that she would be able to see is the immediate moral effect of these experiments upon the subjects themselves—she would not look into the future and appreciate the immense advantage to mankind that must accrue from a successful termination of our research. The future of the world will be assured when once we have demonstrated the possibility of the chemical production of a perfect race.” “Number One, for example,” suggested von Horn.

To one another we may say what we would not think of suggesting to outsiders.” Professor Maxon was mollified by this apology, and turned to resume his watch beside a large, coffin-shaped vat.
