Transcriber’s Notes
Obvious typographical errors have been silently corrected. Variations in hyphenation and ligatures have been standardised but all other spelling and punctuation remains unchanged.
Chapter and some section headings, together with dropped capitals are printed in a black-letter font in the original. This has not been replicated.
Huntilite, in the index, possibly refers to Heliolite in the text, but it is not clear which is intended.
