The original pageheadings have been retained, and moved to appropriate positions in the right-hand margin close to the text to which they refer, so as not to interrupt the flow of the text.

Likewise, footnotes have been moved to the end of the appropriate letter, or the appropriate paragraph in the case of longer passages of text.

Only footnotes in longer letters or passages of text, or those that refer to earlier or later letters etc., are linked.

Initial letters are spaced as in the original, i.e., personal initials: spaced; academic initials: unspaced.

Index: Page numbers have been adjusted to allow for the re-positioning of footnotes. Other obvious page numbering errors have been repaired.

The index of this three-volume work is in this volume, with links to all three volumes; and some footnotes are linked between volumes. These links are designed to work when the book is read on line. For information on the downloading of all three interlinked volumes so that the links work on your own computer, see the Transcriber's Note at the end of this book. The Transcriber's note also contains additional information on corrections made.
