But in his own lifetime--nay, within fifteen years--he witnessed a sufficiently satisfying revolution. "I formerly spoke to very many naturalists on the subject of evolution, and never once met with any sympathetic agreement. It is probable that some did then believe in evolution, but they were either silent or expressed themselves so ambiguously, that it was not easy to understand their meaning. Now things are wholly changed, and almost every naturalist admits the great principle of evolution" ("Origin," sixth edition, p. 424). At present the sale of the book in this country approaches forty thousand copies. Its sale in America has been very large; and numerous translations into German, French, Italian, Russian, Dutch, and Swedish, and even into Japanese and Hindustani, have been largely sold. It must always be one of the most valued of all English classics. FOOTNOTES: [9: Mr. Romanes, in his paper on "Physiological Selection" (Journal of the Linnean Society, Zoology, xix. 337-411), has entered upon a most important discussion of this question.] [10: The full text of a large part of Darwin's original chapter on Instinct, which was omitted from the "Origin of Species" for the sake of condensation, is published in Mr. Romanes' "Mental Evolution in Animals," 1883, which also contains many other observations by Darwin.] [11: The reader will thus be able to judge for himself how far Darwin's "Origin of Species" gained, "from the very first outset, universal respect and a fair hearing," as Mr. Grant Allen, with singular forgetfulness, states ("Darwin," p. 112). The violence of the attacks made upon Darwin by the majority of religious and orthodox journals is well known.] CHAPTER VI.
