We have dwelt thus at length upon the history of this eventful voyage, not only because it filled an important space in Darwin's life, but also because it undoubtedly gave rise to the thoughts and speculations which impelled him to devote his life to the study of problems of evolution. It has been shown to some extent, how he saw, without pre-arrangement, just those phenomena which could stimulate his mind, already fit, to its highest flights. We have seen, too, how universal was Darwin's interest in nature, and how sympathetic a heart went with his scientific insight. He had yet to show how masterly was his patience, to work for yet twenty years, in order that he might not by premature publication of a crude theory risk defeat and throw science backward rather than forward. This long patient work was to be the triumph of his genius. FOOTNOTES: [3: This statement by Darwin disposes of Mr. Grant Allen's assertion that geology was Darwin's "first love" (p. 36). He reckoned himself an entomologist when he went to Cambridge, and certainly Mr. Ainsworth's statement shows that he was a naturalist in a wide sense while at Edinburgh. C. V. Riley, the well-known American entomologist, says (Proceedings of the Biological Society of Washington, U.S., vol. i., 1882, p. 70) "I have the authority of my late associate editor of _The American Entomologist_, Benjamin Dann Walsh, who was a class-mate of Darwin's at Cambridge, that the latter's love of natural history was chiefly manifested, while there, in a fine collection of insects." Indeed, he was one of the original members of the Entomological Society of London, founded in 1833, and showed an active interest in its affairs throughout life, being elected a member of its council in 1838. As early as January 4, 1836, a memoir based on insects sent home by Darwin from Chiloe, was read before the Society by Charles Babington, now Professor of Botany at Cambridge.] [4: Mr. Grant Allen ("Darwin," p. 42) states that Darwin observed sixty-seven distinct organic forms in the fine dust which fell on deck. It was Ehrenberg who determined these organisms in dust sent to him by Darwin, and four out of five of the packets of dust sent to Ehrenberg were given to Darwin by Lyell (Darwin's Journal, second edition, p. 5).] CHAPTER III.
