Note 917 — Chapter VI · SCIENCE AND COMMUNAL POETRY

See Lloyd Morgan, Habit and Instinct, Chap. II. Solitary chicks hatched in an incubator can be heard chirping, all in the same way, before they break the shell, and with no chance of imitation in the case. Weismann, “Gedanken über Musik,” Rundschau, LXI. (1889), 63, remarks that a young finch brought up alone will sing the song of its kind, “but never so beautifully as when a good singer is put with him as teacher.” The concession is enough.
