Transcriber’s Notes

Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.

Simple typographical errors were corrected; occasional unbalanced quotation marks were remedied when the correction was apparent, and otherwise left unresolved.

Index not checked for proper alphabetization or correct page references.

Some images have been rotated 90° to make them easier to read.

In the original book, two or three images often were placed on the same page and sometimes overlapped each other to save space. In this eBook, they are shown separately, in Figure-number sequence.

Images have been moved, when necessary, between paragraphs, so the page numbers in the List of Illustrations do not always match the actual positions of the images in this eBook.

Images were of various sizes in the original book. Here, most are shown at a uniformly-large size, while a few are shown even larger to make details and text identifications readable.

Fig. 2.9 was printed as shown, apparently mirror-image, perhaps as a rubbed impression.

Fig. 7.4 had no caption; the one shown in this eBook was copied from the List of Illustrations.

Fig. 8.7’s “Legend” was difficult to read and has not been transcribed.

Page 301: “CXX” was enclosed in a rectangular medallion.
