In publishing a Second Edition (1875) of the Dialogues of Plato in English, I had to acknowledge the assistance of several friends: of the Rev. G.G. Bradley, Master of University College, now Dean of Westminster, who sent me some valuable remarks on the Phaedo; of Dr. Greenhill, who had again revised a portion of the Timaeus; of Mr. R.L. Nettleship, Fellow and Tutor of Balliol College, to whom I was indebted for an excellent criticism of the Parmenides; and, above all, of the Rev. Professor Campbell of St. Andrews, and Mr. Paravicini, late Student of Christ Church and Tutor of Balliol College, with whom I had read over the greater part of the translation. I was also indebted to Mr. Evelyn Abbott, Fellow and Tutor of Balliol College, for a complete and accurate index.
