Try this link Rhiannon - https://archive.org/stream/anewandcomplete00hollgoog#page/n139/ The 9/ at the end should take you to page 90 which is the page following the illustration. I thought the book was A new and complete history of the county of York' by Thomas Allen, v4, 1831 but maybe I’m getting mixed up.
