his Didot edition he gives a Latin translation that is more original than the translation of Schneider, which largely follows the earlier version of Turnebus. In 1902, a French translation of the treatise was published by Mély13 in a collection of texts and translations of early works on precious stones. In the same year Stephanides published a valuable list of emendations in the Greek periodical Athena.14, These have been added to the list of variant readings in this book. Finally, in 1922, Mieleitner15 published a German translation, based on Wimmer's text, in an article on the history of mineralogy in ancient and medieval times.
In addition to these complete publications of the treatise in one form or another, excerpts of various parts of it have been published from time to time in various languages in a number of scattered works. The most extensive publication of such excerpts is that of Lenz,16 who made German translations of many parts of Hill's English translation and added numerous short notes, most of them original, on the significance of the various passages and on the identification of the minerals and localities mentioned by Theophrastus. The most recent is that of Drabkin,17 who gives an English translation of 17 sections of the treatise. Aside from these partial translations, only a few other studies of parts of the treatise have appeared. Schwarze18 began a Latin commentary in 1801, and had published seven parts by 1807. In 1896, Stephanides19 published an important study of the treatise. Ruska's work, Das Steinbuch des Aristoteles?0 deals with a much later treatise on stones incorrectly attributed to Aristotle, but he refers to the treatise of Theophrastus in his introduction. Reference is made in the Commentary to some of these translated excerpts and special studies, particularly to the interpretations advanced by their audiors.
