Changes made
Some obvious minor typographical and punctuation errors and misprints have been corrected silently.
Some minor lay-out inconsistencies have been standardised without further remarks; where necessary, table and text-elements have been re-arranged and aligned in accordance with the description given.
The part numbers have been inserted on the blank pages preceding each part.
Throughout the book, items from one category (preceded by an Arabic number) are occasionally printed split over two pages, with one or more items from other categories (often preceded by a Roman numeral) between the several parts. For this text, these split items have been recombined on the page where they originally started, and references to their respective parts have been deleted.
The part numbers (I, II and III) have been added to the page numbers for easier reference.
Items in dotted boxes do not occur as such in the original book but have been transcribed schematically from the illustration.
