Transcriber’s notes:

The text of this e-book has largely been preserved in its original form. However, some [spelling errors] have been corrected and some missing punctuation items inserted (hyphen, space, parenthesis, quotation mark). [Inconsistent spellings] have not been changed. Missing footnote markers on pages 96 and 136 have been inserted at what seemed to be likely locations. A few long paragraphs have been split to allow repositioning of diagrams closer to the relevant text. Two diagrams have the same number (Fig. 24.).

Hyperlinks are indicated by a black underline and coloured highlighting when the mouse pointer hovers over them. Page numbers are shown in the right margin. Footnotes have been numbered consecutively and are located at the end. Footnotes have been numbered consecutively and are listed at the end.

The cover image of the book was created by the transcriber and is placed in the public domain.
