Transcriber’s Notes

Inconsistent and unusual spelling, hyphenation, use of accents and lay-out have been retained, except as mentioned below.

Plates at the end of the text are linked to larger versions (not available in all formats).

There are two sets of numbered illustrations: numbered illustrations in the text, and numbered illustrations in the plates in the back of the book. Hyperlinks have been provided to the proper plate or illustration.

Calculations and tables have been copied verbatim although some contain calculation errors.

Some reference letters in the text are missing from the illustrations.

Changes made:

Tables and illustrations have been moved to between paragraphs; some of the plates have been rotated.

Some minor typographic errors have been corrected and some missing punctuation has been added silently.
