had an effect of which I have little reason to complain, for I was allowed almost to call them life-long self-deceivers to their faces, and they said it was quite true, but that it did not matter. I must not conclude without expressing my most sincere thanks to my critics and to the public for the leniency and consideration with which they have treated my adventures. June 9, 1872.   Preface to the Revised Edition My publisher wishes me to say a few words about the genesis of the work, a revised and enlarged edition of which he is herewith laying before the public. I therefore place on record as much as I can remember on this head after a lapse of more than thirty years. The first part of »Erewhon« written was an article headed »Darwin among the Machines,« and signed Cellarius. It was written in the Upper Rangitata district of the Canterbury Province (as it then was) of New Zealand, and appeared at Christchurch in the Press newspaper, June 13, 1863. A copy of this article is indexed under my books in the British Museum catalogue. In passing, I may say that the opening chapters of »Erewhon« were also drawn from the Upper Rangitata district, with such modifications as I found convenient. A second article on the same subject as the one just referred to appeared in the Press shortly after the first, but I have no copy. It treated Machines from a different point of view, and was the basis of pp. 266-270 of the present edition of »Erewhon.« This view ultimately led me to the theory I put forward in »Life and Habit,« published in November 1877. I have put a bare outline of this theory (which I believe to be quite sound) into the mouth of an Erewhonian philosopher in chapter XXVII of this book. In 1865 I rewrote and enlarged »Darwin among the Machines« for the Reasoner, a paper published in London by Mr. G. J. Holyoake. It appeared July 1, 1865, under the heading, »The Mechanical Creation,« and can be seen in the British Museum. I again rewrote and enlarged it, till it assumed the form in which it appeared in the first edition of »Erewhon.« The next part of »Erewhon« that I wrote was »The World of the Unborn,« a preliminary form of which was sent to Mr. Holyoake's paper, but as I cannot find it among those copies of the Reasoner that are in the British Museum, I conclude that it was not accepted.
