This is a note on the differences between editions.   There was next to no difference in font between the 1597, 1633 and 1636 editions of the Herball, with the exception of the use of black letter fonts, which were used more in the indexes of the 1597 edition, and more in the text of the 1633 and 1636 edition when indicating names in other languages.  The 1633 edition (edited by Jacob Thompson) is much longer than the 1597 edition; the 1597 edition consists of 1,392 pages, while the 1633 and 1636 editions total 1,598 pages (excluding the indexes and additional front matter in both cases; the 1633 edition had much more front and back matter than the 1597 edition; the 1636 edition was the same as the 1636 edition).

The woodblock illustrations ornamenting the pages in the 1633 edition (and thus also the 1636 edition) were much more elaborate than the 1597 edition.  For comparison, the chapter title pages and last page of Book 3 are included in the gallery below:
