Removed extra comma on page 153: of the present, epoch.

Left the list numbering as is at the beginning of Chapter II of Part IV, even though the list begins at item c, as if it continues the list which began in the previous chapter.

Footnotes were collected at the end of each chapter, and text was flowed to move illustrations between paragraphs. This has some effect on the index, since the referred-to text may have been moved to a different page.
