In this transcription a black dotted underline indicates the presence of a hyperlink to a specific page or illustration; hyperlinks are also indicated by teal highlighting when the mouse pointer hovers over them. A red dashed underline indicates the presence of a transcriber’s comment; hovering the mouse pointer over such underlined text will reveal the comment. Page numbers are shown in the right margin.

The text contains numerous inconsistencies involving spelling, hyphenation, punctuation, and other aspects. Some of the spelling variations possibly represent authentic contemporary alternatives while others may be attributable to the variety of languages occurring in the book – English, Italian, German, Spanish, Danish, Swedish, Dutch, French, Portuguese and possibly others.

Spelling inconsistencies that are clearly typos have been corrected where appropriate but those representing alternative spellings have been left unchanged. A list of corrections and common inconsistencies is appended at the end of the book.

Punctuation anomalies have been corrected silently (e.g. missing periods, commas and semicolons, incorrect or missing quotation marks, unpaired parentheses), particularly in the extensive bibliographic lists, in the index and in the Figure captions.

There is significant inconsistency between the headings displayed in the Table of Contents (TOC) and those in the text, most noticeably in Book II where the last four entries in the TOC are appropriately identified as Sections II, III, IV, and V but the corresponding headings in the text are incorrectly named as Section II Part I, Part II, Part III and Part IV. TOC headings and text headings also vary in their specific wording and the presence or absence of parentheses and dashes.

Inconsistent ways of expressing measurements are as in the original, for example, one fifth of an inch, 1/5th of an inch, 1/5 of an inch, 1/5″ of an inch, 1/5″.

The dimensions of many organisms are described using an archaic unit of length: the ‘line’ which was equivalent to 1/12 of an inch. However, as the inch itself varied, both within and between countries, it was a non-standard measurement, e.g. in England one line was equivalent to 2.117 mm but the French (Paris) ligne was equal to 2.256 mm. The triple prime symbol ‴ was used to represent the unit and occasionally appears in this text (along with the more common ′ and ″ symbols representing feet and inches). The ligne unit is still used by watchmakers.

The closing pages of the book contain advertising material about other works from the same publisher. In some cases the date of publication could not be determined with certainty because of the inferior quality of the page scans.
