The following account of the structure of the  book makes no pretense
to be complete; nor is it in every respect completely accurate. It is
a naive account, along taxonomic lines, which it is hoped will  be of
use to  the reader.   The  book is divided  into chapters,  which are
divided  into sections, which are divided  into paragraphs, which are
divided into  sentences,  which are  divided  into words,  which  are
divided  into letters. For  reference purposes,  each letter  in this
book has  a unique  number (actually  a finite  sequence of  positive
integers) attached to it.  The first  sequence has exactly six terms,
so  that the  book, considered  as a finite  sequence of  letters, is
mapped into N⊗Bo⊗*⊗A6⊗*.  It has been found very convenient  for both
the author and reader to do this abstractly, rather than concretely.
