[0] The pagination of the printed book could not be totally reproduced in this eText. The illustrations, which don’t carry a page number, take up two page numbers—hence the “gaps” in the page numbering you see in this eText. Similarly, as the illustrations are inserted somewhat randomly and with no reference to the text, they often appear in the middle of paragraphs which have nothing to do with them.

Most page numbers related to the illustrations have been removed in this etext, and the list of illustrations has had the page numbers adjusted to those pages which carry page numbers in the printed book.

Lastly, the filenames of the illustrations are based on their original but unprinted page numbering in the book. E.g. an illustration named “p47.jpg” would be where page 47 of the printed book should be.—DP.
