[D] My friend Mr. J. J. Walker, R.N., tells me that the house in which Wallace lived in Ternate, and in which the essay was written, is still pointed out by the natives as one of the features of the place. It is, unfortunately, much dilapidated. [E] 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.” [F] Since the above paragraph was written I have again read Professor Newton’s eloquent Address to the Biological Section of the British Association at Manchester in 1887, and find that he says on the same subject--“If in future you should meet with any cynic who may point the finger of scorn at the petty quarrels in which naturalists unfortunately at times engage, particularly in regard to the priority of their discoveries, you can always refer him to this greatest of all cases, where scientific rivalry not only did not interfere with, but even strengthened, the good-feeling which existed between two of the most original investigators” (Report of Meeting, p. 731).
