The two editions are combined because of missing pages in one and missing images in the other.
Page numbers in this book are indicated by numbers enclosed in curly braces, e.g. {99}. They have been located where page breaks occurred in the original book.
Obvious spelling errors have been corrected but "inventive" and inconsistent spelling is left unchanged.
