2. Obvious typographical errors have been corrected. Other than these and particular changes noted below, inconsistencies in spelling have been retained as printed.

Where a word is used repeatedly in the same way, hyphenation has been made consistent, preferring the form most often used in the printed work, or failing that the more usual form in general use at the time of publication.
