Piety towards Dr. Jowett, whose munificence has made possible the production of this translation of Aristotle, suggested that no new rendering of the Politics should be attempted, but that his translation should be re-issued. Much valuable work has been done, however, on the Politics since his translation was published in 1885, and of this I have endeavoured, in revising his translation, to take account, while preserving as far as possible the ease and grace of the original rendering. The revised translation is based on Immisch's edition in the Teubner series (1909), but I have not hesitated to depart from his text where he deserts the MSS. unnecessarily, or where a better emendation seemed possible ; all such departures have been indicated in the notes. In particular, I have added one more to the many attempts that have been made to emend the corrupt passage iv. i30oa 23~b 5.
