    Notes to pp. i8^-g4 IO.2:MS p. 77 ['58' deleted]). My guess is that p. 58 was the next to the last page of the original draft of Chapter VI. This sentence was canceled and p. 59 discarded when the section on the principle of divergence was added. 61 Natural Selection, pp. 174, 219. 62 Ibid., pp. 280-1 (this appears to be part of the original draft). 63 LLD, 1:461-2. The difference between the pre- and post-Lubbock methods is discussed in Browne, Darwin's Botanical Arithmetic, pp. 78-9. The pre-Lubbock method is that used in the calculation based on Boreau given in n. 39, above: The post-Lubbock method is that displayed in Natural Selection, pp. 148-55. Karen H. Parshall has shown that even after the Lubbock episode Darwin's procedure was faulty, so that the figures as given in Natural Selection do not logically bear on the question Darwin was addressing. Furthermore, she shows that the results given in Natural Selection are not statistically significant; Varieties are Incipient Species: Darwin's Numerical Analysis (unpublished essay; I am grateful to its author for permission to refer to it). 64 Natural Selection, pp. 145-6. 65 Ibid., pp. 243-4. 66 Ibid., p. 165. The same idea is expressed in a letter to Hooker in 1853 {LLD, 1:400). 67 Natural Selection, p. 249. 68 LLD, 1:462-3, 481; MLD, 1:99. 69 MLD, 1:105-8; DAR 114:227, 228. Darwin discussed Hooker's chief objection in Natural Selection, pp. 155-9. 70 MLD,i:iog. 71 Darwin, Autobiography, p. 120. 72 On the debate between proponents of ecological and geographical speciation, see Ernst Mayr, Evolution and the Diversity of Life, pp. 117-217. See also Sulloway, Geographic Isolation in Darwin's Thinking, pp. 23-65- 73 Darwin wrote Hooker in 1862 that the principle of divergence was the best point which, according to my notions, I made out, and it has always pleased me {MLD, 1:199). 8.
