As seen on Ebay
The blurb reads:
Don't get TOO excited, this is a nicely bound copy of a photocopy (of a photocopy) of the original 1880 volume. Check the photographs carefully. Someone had a photocopy of the book (two pages to a sheet) and it was heavily underlined. The photocopies were all then folded in two and "perfect bound" together. It means that you have two pages of text, and then two blank pages throughout the book, so the width of the volume is twice the normal size. What you are buying here is basically a nicely bound volume to go in the bookcase; something that LOOKS good, but ultimately is just a so-so copy of J H Paton's work.
