    CD sent Pictet de la Rive a presentation copy of Origin (see Appendix III). CD had been impressed by the discussion of the species question in Pictet de la Rive 1853--7 and thought that Pictet might be swayed by his theory. See Correspondence vol. 7, letters to F. J. Pictet de la Rive, 11 November [1859], and 24 December [1859].
