At Snowbell's suggestion, I've added a table of contents to the start of this document, to make it easier to find things. I've also added captions to the figures, and included them in the table of contents.
The updated document is available by following the links I gave in my first posting. In addition, I've made the Word version available directly, without needing to use WinZip. The link for this is:

You will find that this document opens in the browser (if you are using Internet Explorer), rather than automatically coming through as a download. To save it as a Word document on your PC, use the Save As option from the File menu in the browser. (Netscape users don't have this difficulty, as it asks you whether to open the document in Word or save the file to your disk.)
