TRANSCRIBER'S NOTE Italic text is denoted by _underscores_. Exponents are denoted by ^ so for example 4^2 indicates 4 squared. For consistency and clarity, a space (when absent) has been placed between the number and the unit of weight lb. and lbs. giving for example '21 lbs.' in place of '21lbs.' Fractions, usually in the form '14 3-4' in the original text, have been converted to the form '14-3/4' in this etext. Fractions in all tables have been converted to Unicode ½ ¼ ¾ ⅓ etc., for clarity and to conserve space in larger tables. A few tables have non-Unicode fractions which remain in the form 1-7/12. Also, in a few larger tables with italic styling on some text, this italic styling has been removed, for clarity and to conserve space. In a few cases a word has been abbreviated to conserve table space: cal. = caliber; diam. = diameter. Some instances of _Tome_ in French citations have been changed to Tome (no italic), for consistency. Some accents and spelling in French citations have been corrected. For consistency, instances of 'fireworks' and 'fire works' have been changed to the predominant form 'fire-works'. Obvious typographical errors and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources. More detail can be found at the end of the book.
