was resident in Köthen (Anhalt) in Germany. It contained 317 aphorisms. Though French and Italian translations exist, this edition has never been translated into English. On page 3 of the Italian translation of Organon 3, the following quotation from Seneca the Younger appears: "Non enim cuiquam mancipavi, nullius nomen fero: multum magnorum judicio credo, aliquid et meo vindico." (Seneca the Younger, Epistulae Morales ad Lucilium – Epistle 45.4, Moral Letters to Lucilius) "For I have sold myself to no-one; I bear the name of no master. I give much credit to the judgment of great men; but I claim something for myself." This quotation does not appear in any of the other Organon editions or translations, and was probably therefore added by the translator of the Italian edition. Fourth edition The fourth edition of the Organon was published in the year 1829 when Hahnemann was living in Köthen. It contained 292 aphorisms. An English translation by Charles H. Devrient was published in Dublin in 1833. Hahnemann's miasm theory, deriving from his two volume work, The Chronic Diseases published the previous year (1828), was first alluded to in this edition. Likewise, the 'vital force' theory makes its first significant appearance in this edition. Fifth edition The fifth edition of the Organon was published in the year 1833 when Hahnemann was living in Köthen. It contained 294 aphorisms. It was later twice translated into English by Robert Ellis Dudgeon, first in 1849 and again in 1893. The fifth edition of the book was also translated to English by C. Wesselehoft. This fifth Organon departed significantly in style and content from the four previous editions by making numerous references to metaphysical notions like the vital force, miasms and potency energy. Sixth edition The sixth edition of the Organon was not a full edition in the usual sense but merely a copy of the 5th Organon which Hahnemann had annotated in February 1842 with numerous revisions before his death in 1843 in Paris. In a letter from Paris dated June 1, 1841 he states, "I am preparing the sixth edition of the Organon, to which I can only devote a few hours on Thursdays and Sundays." However, in a letter to his publisher in Düsseldorf, dated 20 Feb 1842, he wrote, "I have now, after eighteen months of work, finished my sixth edition of my Organon, the most nearly perfect of all."
