I have this as a e-book as it's a public domain, but I wanted to have a hard copy, so I can ubderline some passages and such.
The paper is nice. It contains editor's preface dating 1847. It also has comments from this editor throughout the text explaining things to the readers of his time. The text is on a small side and the side borders are1,5 cm wide which makes for a smaller book than it could have been. I'd personaly prefer a thicker book.
