Transcriber’s Notes:

Footnotes have been moved to the end of the text and relabeled consecutively through the document.

Illustrations have been moved to paragraph breaks near where they are mentioned.

Punctuation has been made consistent.

Variations in spelling and hyphenation were retained as they appear in the original publication, except that obvious typos have been corrected.

Abbreviations for references have inconsistent spacing, such as c1 versus c 1, and these have been left as they appear in the original publication.

Changes have been made as follows:

Footnote 86: Struycken changed to Struyken (A; Struyken; Davignon)

Footnote 139: Reference letter is missing and is probably d (d 94).
