Transcriber’s Notes:

The cover image is in the public domain.

Antiquated spellings were retained.

The illustrations have been moved so that they do not break up paragraphs and so that they are next to the text they illustrate.

Typographical errors have been silently corrected but other variations in spelling and punctuation remain unaltered.

Added “Spodumene 96” to TOC, as it was missing.
