Footnote Issues

In these notes, "anchor" means the reference to a footnote, and "footnote" means the information to which the anchor refers. Anchors occur within the main text, while footnotes are grouped in sequence at the end of this eBook. The structure of the original book required some exceptions to this, as explained below.

The original text used chapter endnotes. In this eBook, they have been combined into a single, ascending sequence based on the sequence in which the footnotes (not the anchors) occurred in the original book, and placed at the end of the eBook.

Three kinds of irregularities occurred in the footnotes:

1. Some footnotes are referenced by more than one anchor, so two or more anchors may refer to the same footnote.
2. Some anchors were out of sequence, apparently because they were added afterwards or because they are share a footnote with another anchor. They have been renumbered to match the numbers of the footnotes to which they refer.
3. Some footnotes have no anchors. These are noted below.
