Plates and illustrations: the spelling and/or language of the captions may differ significantly from those in the body of the text and the Index to Illustrations. Some captions were largely illegible, and have been reconstructed based on the Index of Illustrations or on the main text where possible. Underneath each plate in the end of the book are the (usually enlarged) individual illustrations from the plate. Several of the illustrations were of rather poor quality, and it may not always be possible to read measurements or texts inside illustrations, nor has it always been possible to transcribe them. Where possible and necessary to see all details, hyperlinks to even larger illustrations have been provided (available in the on-line html format, but not necessarily in other formats). Several of the individual illustrations lack a caption; only when it is clear what the caption should be (i.e., a clear, unambiguous illustration that is listed in the Index of Illustrations) has a caption been inserted, as listed below. Some illustrations have been rotated or otherwise re-arranged for better readability or visibility
Changes made
Several obvious typographical and punctuation errors have been corrected silently.
Ditto characters have in several cases been replaced by the dittoed text.
Footnotes have been moved to directly under the paragraph to which they belong.
Some tables and mathematical formulas have been re-arranged or re-aligned for better readability.
