General Notes.
The relative size of items noted in the captions of the Plates relates to the original book, not to this document. Scaling of the images in preparation of this ebook and the size and resolution of the media on which the ebook is read make general statements about relative size of the pictured items impossible.
The "Index" was completely reworked so that it reflects the titles and captions within the body of the book. The original style was maintained. Details of changes to the "Index" are omitted. Links in the "Index" point to the text preceding a Plate, not the Plate itself, whereas the page number indicates the Plate.
When opening the original book to any of the Plate pages, the associated text appeared on the left hand page and the Plate appeared on the right hand page. Therefore, in this ebook, the text associated with a Plate always precedes the Plate.
The text of the book varies from the original in that obvious misprints have been fixed. Where the intent of the misprint was not obvious, it has been left in place and noted below. Use of archaic and unusual words, spelling and styling has been maintained. Inconsistent hyphenation has been retained. Capitalization of botanical names is maintained as in the original. Details of the changes follow.
