Because there are so many Footnotes, these have been moved to the end
of the Introduction and renumbered in sequence from #1.
Variant spelling of Scots words have been left as printed.
When the caret ^ mark has been used within a word, this indicates that
the letter to the right of the mark will be raised in the original.
The equals sign (=) around a word or numbers (e.g. =162=) indicates
that they will show as bold in the final project.
Changes made are noted at the end of the book.
