Also articles on Socrates in Smiths Dictionary of Greek and Roman Biography and Mythology (by John Calrow Means) and Smith & Wace: Dictionary of Christian Biography (William Milligan), as well as passing notices in standard ecclesiastical histories such as Neander, Hase, Killen, Schaff, &c., and Introductory notices of Valesius (Hussey), Parker, Bright, &c.
All works marked with a star in Chevaliers list were used in the present edition, and all but two or three of those added to the list of Chevalier.ix:2
Noltes article is on the textual emendations needed in the edition of Socrates. The text of our historian has not been as thoroughly and completely examined and corrected as other writings. Valesius edition (Hussey) gives an account of a few mss. examined by himself; nothing further has been done of any importance. It is to be hoped that Gebhardt and Harnack may find it convenient to incorporate a new collation and revision in their Texte und Untersuchungen.ix:3

E. Walford, A.M., appears as the translator of Sozomen, not of Socrates. See IV. of Introduction, note 6.
