TRANSCRIBER’S NOTE

These lectures each had a set of associated slides, a completelist of which can be found on pages 143–152 at the end of thebook. These slide sets were sold separately and are not part ofthe book. Some of the slides (those highlighted in bold in theslide list) were inserted as illustrations in the original book,and these are reproduced in this etext.

The numbers in the right margin of the etext are the numbers ofthe associated slides. Several of these margin slide numbers arein parentheses ( ) to indicate that this particular slide is beingshown for a second time at this point in the lecture. These margin slide numbers,like the page numbers, are only displayedon browsers; they are not displayed on handheld ereader devices.

If the window viewing size is made very wide, some slide numbersmight be overlaid on the next one; keeping the text width less than 120 charactersshould avoid this.

The original book showed all the slide numbers as sidenotes in the outermargin of the text. These are not displayed on ereaders, but can be viewed in the .htm and .txtversions of the etext.

There are no Footnotes in this book.

The original cover image has been slightly modified. It had damage in the top leftcorner. This section of the cover image has been overlaid with a rotated version ofthe top right corner section. This modified cover image was created by the transcriberand is placed in the public domain.

Some minor changes to the text are noted at the end of the book.
