- Transcriber’s Notes:
- The raised dot (·), used to indicate multiplication, was confused with the decimal point in several numbers. The raised dot has been changed to the decimal point in numbers and the raised dot used only for multiplication.
- In places where “×” was used for multiplication, it was left as the author wrote it.
- Missing or obscured punctuation was silently corrected.
- Typographical errors were silently corrected.
- Inconsistent spelling and hyphenation were made consistent only when a predominant form was found in this book.
