Transcriber’s Note
Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in the original book; otherwise they were not changed.
Simple typographical errors were corrected; unpaired quotation marks were remedied when the change was obvious, and otherwise left unpaired.
A Table of Contents was added by the Transcriber.
The book cover image was created by the transcriber and is placed in the public domain.
Page [28]: “the races of hands” probably should be “the races or hands”.
Page [32]: “musterial” probably should be “material” or “materials”.
