Tables: Where necessary, the widths of columns have been adjusted, and some tables have been split to accommodate the width restrictions on this text format. Split tables have had blank lines inserted in order to maintain the alignment between the two parts should they be rejoined at a future date. In the original text, Table VI was split over two pages but has been rejoined in this version. References: For ease of searching, references in the text, as well as those in the list of references, have been enclosed in square brackets, e.g. [ref.3]. UTF-8 characters: This version contains UTF-8 characters to represent Greek letters, subscripts, superscripts and some punctuation. If these characters do not appear correctly, you may need to select a different font. In order for the table columns to line up correctly, this will need to be a monospaced, or fixed-width, font.
