Transcriber's note

In the HTML version some of the illustrations have been moved beside the relevant section of the text. Page numbers in the List of Illustrations reflect the position of the illustration in the original text, but links link to current position of illustrations.
Minor punctuation errors have been corrected without notice.
An obvious printer error has been corrected, and it is listed below.
All other inconsistencies are as in the original. The author's spelling has been maintained.
Page 36: "a Saxon ex-example" changed to "a Saxon [example]".
