This text uses utf-8 (unicode) file encoding. If the apostrophes and quotation marks in this paragraph appear as garbage, you may have an incompatible browser or unavailable fonts. First, make sure that the browser’s “character set” or “file encoding” is set to Unicode (UTF-8). You may also need to change your browser’s default font.

Page numbers in italics show the original location of illustrations. Those in bold italics were full-page illustrations. In the body text and the List of Illustrations, links lead to the specific illustration, not to its original location.

Inconsistent capitalization of “mark” is as in the original. Other typographical errors are shown with mouse-hover popups.

The texts of most pictured Marks will appear in plain type if you hover your mouse over the picture. Expanded abbreviations are shown in [brackets]. Words split across line breaks are shown with or without hyphens, as originally printed. Texts that were too long or complicated to display in this way are collected at the end of the e-text.

Technical Note: The illustrations were scanned at 400ppi and scaled to 25% by pixel count. In most browsers they will therefore appear a little larger than originally printed.
