"Fabricius, says Buhle, judges rightly of this edition, when he pronounces it to be more excellent and complete than any that had been before published…Besides containing the correctikons of former publications, and an improved text, there are three indexes to each volume: the first is a short synopsis of the heads of each tract or book; the second an Index 'Verborum Graecorum;' and the third a Latin Index 'Rerum Memorabilium.' In addition to Aristotle's works, it comprehends some tracts of Theophrastus" (Dibdin, Introduction to the Greek and Latin Classics, 4th Edition, I, p. 314).
