Detailed Transcriber's Notes

Obvious misprints have been fixed. Archaic and unusual words, spellings and styling have been maintained when they are used consistently. Spelling has been standardized within the book where one spelling was predominant, even if it is not in common usage. Inconsistent spelling and hyphenation has been maintained when there was not a predominant spelling. Details of the changes follow.

No attempt has been made to correct the capitalization or standardize the italicization of biological names—they are left as in the original.

Hovering over a Greek word will display its transliteration.

All of Darwin's errata have been applied to the text, except the one on page 255. It was not applied because the wording is not obvious.
