Note 29 — PART I PLAYFUL EXPERIMENTATION

Miss Romanes’s account of the capuchin ape perhaps furnishes an example from the animal world: “He pulls out hot cinders from the grate, and passes them over his head and chest, evidently enjoying the warmth, but never burning himself. He also puts hot ashes on his head” (Animal Intelligence, fifth edition, London, 1892, p. 493). The context favours the supposition of playful experimentation.
