Transcriber’s Notes
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; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced.
Illustrations in this eBook have been positioned between paragraphs and outside quotations.
Each Plate in the original book contained two or three photographs and one shared caption. In this eBook, each photograph has its own caption.
This book uses endnotes following each chapter. In the original book, the endnote numbers began at “1” for each chapter. In this eBook, those numbers are retained, but are preceded by the chapter number and a hyphen to make them unique.
A few endnotes include an “a” suffix.
Many references to endnotes that reference another book are followed by a pair of square brackets containing the page number in that other book.
The book also has four footnotes that originally were at the bottoms of pages, but have been moved here to follow the paragraphs that reference them. They use simple “abcd” references.
Three endnotes are unreferenced (XII-14, XIII-2 and XIII-6); several are referenced more than once.
The index was not systematically checked for proper alphabetization or correct page references.
