and of Life and Halit 41 They rather show the preparation of the soil in which those germs sprouted and grew ; and, remembering his last remark on the subject that " it was all very young and silly," I decided to omit them. The Dialogue is no longer lost, and the numbers of - the Press containing it and the correspondence that ensued can be seen in the British Museum. Butler's other two contributions to the Press mentioned above do contain the germs of the machine chapters in Erewhon, and led him to the theory put forward in Life and Habit. In 1901 he wrote in the preface to the new and revised edition of Erewhon : " 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 Canterbury Province (as it then was] of New Zealand, and appeared at Christ- church in the Press newspaper, June 13, 1863.

Further on in the preface to the 1901 edition of Erewhon he writes: " 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. 270-274 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.* / have put a bare outline of this theory (which I believe to be quite sound] into the mouth of an Erewhonian professor in Chapter XXVII of this book." This second article was Lucubratio Ebria, and was sent by Butler from England to the editor of the Press in 1865, with a letter from which this is an extract: " I send you an article which yo^£ can give to FitzGerald or not, just as you think it most expedient—for him. Is not the subject worked out, and are not the Canterbury people tired of Darwinism ? For me—is it an article to my credit ? I do * Life and Habit is dated 1878, but it actually appeared on Butler's birth-day, 4th December, 1877,
