Chance’s beard was darker than his scalp hair and he enclosed these samples to prove it. He also included a meticulous self-description of his body hair and ideas about how he might have inherited it from the maternal and paternal sides of his family. Darwin annotated the letter with a summary and incorporated Chance’s observation into the second edition of <i>Descent</i> as a rare exception to the rule.</p>
