Spelling and punctuation are as in the original, including the consistently "modern" use of V and U. Italic capital V has two forms, used interchangeably. Since italic capital U does not occur, the rounded V-form has been transcribed as U.
Greek words and phrases have been transliterated and shown between +marks+. Hebrew is shown between #marks#.
Latin quotations were given in italics; the translation was usually printed with marginal quotation marks. In this e-text, Latin passages are shown as block quotes (indented) _without_ quotation marks, while passages with marginal quotes are shown as block quotes _with_ quotation marks.
The six Sidenotes shown with an asterisk alongside their number were printed with an asterisk in the original text; all other notes were unmarked.
References from the Sidenotes are identified at the end of the text, followed by a complete list of errata.]
