1. Illustrations in the middle of a paragraph are moved to a paragraph break above or below the paragraph. Where there is no paragraph break on the page, the illustration is moved to the nearest paragraph break in the pages before or after. For smaller half-width illustrations with text wrapping down one side, the image is floated left or right at a suitable paragraph break to resemble the appearance in the original text. The positioning of illustrations may cause the amount of text between page number anchors to be smaller than usual.
2. Full page illustrations. With the exception of the illustration on Page 10, full page illustrations in the original text had blank reverse sides which were included in the page number count. In the html, such illustrations carry a two-number page anchor e.g. [53-4]. Where full page illustrations occur in the middle of a paragraph, they and their page anchors are moved upwards to the nearest paragraph break. The page anchors remain in sequence but some text in the page before the illustration will have been displaced from its page anchor and will appear below the illustration.
3. Original page numbers in the list of illustrations have been retained, however the underlying links have been edited to navigate directly to the illustrations since they may have been repositioned.
Original page numbers in the index have been retained (except for the typo correction on page 266 ("Ostrich", see above). Html links navigate to a page anchor for the given page number unless the indexed content has been displaced by the repositioning of illustrations. In such cases, the links have been edited to navigate directly to the indexed content.
