Luck or Cunning

This book, as I have said in my concluding chapter, has turned out very different from the one I had it in my mind to write when I began it.  It arose out of a conversation with the late Mr. Alfred Tylor soon after his paper on the growth of trees and protoplasmic continuity was read before the Linnean Society—that is to say, in December, 1884—and I proposed to make the theory concerning the subdivision of organic life into animal and vegetable, which I have broached in my concluding chapter, the main feature of the book.
