Transcriber's note

• Original spelling, hyphenation and punctuation have been kept, but variant spellings were made consistent when a predominant usage was found.
• Footnotes have been renumbered and moved to the end of the book.
• Blank pages have been skipped.
• Obvious printer errors have been silently corrected, after comparison with a later edition of this work. Greek text has also been corrected after checking with this later edition and with Perseus, when the reference was found.
• Some inconsistencies in the use of accents over proper nouns (like “Alkibiades” and “Alkibiadês”) have been retained.
• The following changes were also made, after checking with Perseus and other editions:

  note 337:	“Thucyd. vi, 69”	→	“Thucyd, i, 69”
  note 573:	“vii, 73”	→	“viii, 73”

• The book cover image was created by the transcriber and is placed in the public domain.
