Charles V. De Vet, Death of a mutant (1956)

"I suppose if the profs and psychiatrists at the U couldn't find a way to talk with you, I can't. I understand when they couldn't learn how you mutants read minds—or even if you did—they tried to teach you to speak, and to live like human beings. You couldn't, or wouldn't, learn either. You wouldn't work, and nothing seemed to interest you. Until toward the end you turned surly, and scratched and even bit people who annoyed you." ”
