`One may recommend this book as a happy illustration of how much useful and interesting information a diligent editor may prize from an apparently unpromising source...The general editors have clearly given much thought to the system of textual and editorial conventions, which are in every case clear and readily intelligible, The introduction is provided with many cross references. The book has been beautifully printed and scrupulously proof-read. If the forthcoming volumes maintain the standard of this one, the series deserves to succeed. D.R.
