Page proofs of the volume which have been bound in a temporary soft jacket. This has been marked as the index copy. It is an uncorrected version of the text, in which different layers of correction have been made - in blue, red and black ink (including some apparently by a proof reader and some probably by Hamburger himself). The proofs have been used for compiling the index of the volume: every proper name in the book has been underlined in blue ink. A section of galley proof has been inserted at p. 81 containing a part of the text which was substantially revised for publication; this has also been used as index copy. Consequently pages following p. 81 have been renumbered by hand, so that there are no pp. 82-83.
