This is 
          the fullest version of the book when it reached its maximum length, 
          by 18th July 1995. It was then cut back and a good deal omitted in the 
          final, published version. Please note that this is a very rough draft, 
          with references, grammar etc. largely unchecked. As well as the texts, 
          there are 36 appendices, 
          referred to in these chapters, which provide detailed discussions of 
          specific topics.
