PREFACE TO THE PARVA NATURALIA

each translation to its author, whose name will in all cases be given.

Translators have been found for the Organon Aristotle's logical works, Physics, De Caelo On the Heavens, De Anima On the Soul, Historia Animalium History of Animals, De Animalium Generatione On the Generation of Animals, De Insecabilibus Lineis On Indivisible Lines, Metaphysics, Eudemian Ethics, Rhetoric, and Poetics, and it is hoped that the series may in course of time include translations of all the extant works of Aristotle. The editors would be glad to hear of scholars who are willing to undertake the translation of such treatises as have not already been provided for, and invite communications to this end.

The editors desire to acknowledge their obligation to Mr. Charles Cannan for valuable aid in the revision of the present volume, and to Mr. G. R. T. Ross for the preparation of the Index.
