![б DARWINISM AND HUMAN LIFE were punctuated by the completion of book after book—the milestones of my life, as he called them ; and it may be useful to note that Darwin recognised three stages in his career as a biologist : (1) the mere collector at Cambridge ; (2) the collector and observer on the Beagle voyage (to which he thought he owed the first real training and education of his mind) ; and (3) the trained naturahst after his eight years' work on barnacles. His books may be arranged in three groups : [а] The early zoological and geological studies, e.g. Zoology and Geology of the Beagle (1840- 46), Coral Reefs (1842), Monograph on the Cirripedia (1846-54). Although the book on Earthworms was not published till 1881, it was begun more than forty years before, and may be included in the first series. (б) The series of evolutionary volumes : The Origin of Species (1859) ; Variation of Ani¬ mals and Plants under Domestication (1868) ; Descent of Man (1871) ; Expression of the Emotions (1872). (c) The botanical books—largely influenced by evolutionary ideas : Fertilisation of Orchids (1862) ; Movements and Habits of Chmbing Plants (1875) ; Insectivorous Plants (1875) ; Cross and Self-fertilisation in Plants (1876) ; The Different Forms of Flowers in Plants of the same Species (1877) ; The Power of Movement in Plants (1880).
