Reading edition
Wallace has added the following note to the reprint in “Natural Selection and Tropical Nature,” London, 1891, p. 31: “That is, they will vary, and the variations which tend to adapt them to the wild state, and therefore approximate them to wild animals, will be preserved. Those individuals which do not vary sufficiently will perish.”
