The text is intended to reproduce the layout of the original as closely as possible. If you see a horizontal scroll bar, it may help to make your browser window narrower (not wider).
Headnotes were printed at the top of alternate pages, like subsidiary chapter headings. They have been retained in the introductory section but were omitted from the main text to reduce visual clutter.
Text-Critical Notes and variant readings have been handled differently than in the printed book, where they appeared either as footnotes (numbered) or sidenotes (sometimes but not always marked). Here, the word they refer to is underlined if necessary, and the note itself will generally have this form:
leak] the t of the MS. has a k over it.
The title page was printed again [before the General Preface]. In the e-text it will there be shown as plain text.
Typography of the table of contents is as close as possible to the original. Titles shown in small capitals generally represent longer selections.
