● Transcriber’s Notes: ○ Missing or obscured punctuation was silently corrected. ○ Typographical errors were silently corrected. ○ The notation “H_{2}O” uses the underscore and braces to mean a subscripted
    character. In this case the formula for water.
    ○ Inconsistent spelling and hyphenation were made consistent only when a predominant form was found in this book. ○ Text that was in italics is enclosed by underscores (italics).
